2021 Hyundai Elantra: Recalls, Complaints & California Lemon Law

NHTSA Recall Number 22V354000 has been active since May 18, 2022. The dealership says no dealers in the area have received the part to fix it. The recall itself carries serious safety concerns as the seatbelt will explode metal fragments in an accident. The dealer has also told me that 35 other people are waiting for the recall to be fixed as well. This is ridiculous, Hyundai needs to get these parts to the dealers.

Description of the Safety Problem: In the early morning hours of January 8, while driving my Hyundai vehicle, I ran off the road into a ditch. I was extremely disoriented and activated the vehicle’s built-in Blue Link SOS emergency assistance system for help. I successfully connected with a Blue Link operator and repeatedly told her that I did not know where I was and that I was scared and needed assistance. While I was actively requesting help, the SOS call was disconnected. After the disconnection, I attempted to reconnect using the SOS system but was unable to do so, despite the vehicle having power and an active, paid telematics subscription. The system did not reconnect or provide further assistance. I was forced to call 911 from my personal cell phone to obtain emergency help. This resulted in a delayed response and a $1,300 towing expense that I would not have incurred if the SOS system had functioned as marketed. This incident raises serious safety concerns. The vehicle’s emergency SOS system failed during an active emergency, disconnected while the driver was disoriented and requesting help, and provided no ability to reconnect. This defeats the purpose of an integrated emergency safety feature and could place drivers at risk of serious injury or death. I am reporting this incident so NHTSA can evaluate the reliability and safety of Hyundai’s Blue Link SOS emergency system during real-world emergencies.

Allegedly reported: 1 injury (as reported to NHTSA). NHTSA #11710172

Subject: Vehicle Safety Complaint – Engine Failure – Hyundai To Whom It May Concern, I am submitting a vehicle safety complaint regarding a serious engine failure involving my Hyundai vehicle. The engine experienced a failure significant enough to require replacement. This raises serious safety concerns, as sudden engine failure can result in loss of power while driving, increasing the risk of an accident. In addition: •Hyundai Motor America has not adequately addressed the issue •My case (#xxxx) remains unresolved despite escalation •I have experienced delays, lack of transparency, and no meaningful resolution Given Hyundai’s known history of engine-related issues, I believe this may represent a broader safety concern affecting other drivers. I respectfully request that NHTSA: 1.Review this incident as a potential safety defect 2.Investigate whether this issue is part of a larger pattern 3.Take appropriate action to ensure consumer safety I am available to provide documentation and further details if needed.

I was driving on a 40mph speed road at 45 mph and the car stopped accelerating abruptly and remained stuck at 20 mph even thou my foot was on the gas pedal. I had to put the caution lights on and get to the side of the road. I had every car behind me honk and yell when passing by. This could have been a big crash. I have the video of this when I was driving. This happened various times, in December, Feb and last week.

One day I was on the highway driving and the front collusion safety warning appeared. I thought the warning went off because the sensor was dirty due to dead bugs. However, I pulled over and the sensor did not appear dirty. After awhile the sensor went off on its own. Then a few weeks late the front collusion safety warning appeared again while I was driving on the highway. The warning has not fixed itself. I cannot use my cruise control. I took it to the Hyundai dealership and they told the me senor is off alignment and it will cost $500 to repair because they have to remove the entire bumper. I have seen on Hyundai forums this is a common problem.

NHTSA #11603543

Driving on highway, dashboard reported "Check Forward Safety System" and "Check Smart Cruise Control System". The car then disabled both while I was driving. This has happened 6 times to me. The first time I brought it to dealer and they stated it was a calibration problem. They reset it and I had no problems for a while. The problem has occurred 5 times more and will stay on for about a week or so and then just go away. It works again and then occurs again. So, it is intermittent and recurring. Each time the diagnostic code reported by the software to my phone is C162078. I see the 2018 Kona had the same exact problem and a software update TSB was put out there.

car problems started with back up camera not working, it has caused dash lights to go out, headlights to go out while driving safety sensors to sound for no reason. I have also started having problems with radio flashing and going blank. The vehicle has been checked by Hyundai dealer they did say back up camera bad but no answers for rest of issues.there were no warning lights prior to any of these problems. I still do not know what is really wrong and cannot drive vehicle at night or bad weather for fear of losing headlights. Vehicle is 2021 hyundai elantra with 10,500 miles on it.

I am writing to report a serious and ongoing safety issue with my 2021 Hyundai Elantra Hybrid that remains unresolved despite multiple visits to Hyundai service centers and independent repair shops. I’ve also found numerous consumer discussions online describing nearly identical issues with the same model and newer Elantra Hybrid models, suggesting this may be part of a wider systemic defect. The core issue lies within the vehicle’s hybrid system. Shortly after a recent system/software update performed at a Hyundai dealership, a warning message began appearing at random intervals stating: “Check Hybrid System.” This typically first appears after extended driving — often around 3 hours — but once it occurs, the issue worsens if I continue to drive. Each time the warning appears, the vehicle suddenly and drastically decelerates without driver input, becoming dangerously slow and unresponsive, even while traveling at highway speeds. This creates an urgent safety risk, as I have had to maneuver off the road quickly to avoid collisions. After the initial warning, if I attempt to drive the vehicle again without sufficient downtime, the warning reappears much more frequently — sometimes within minutes. The only temporary relief is to stop using the vehicle and allow it to rest for at least six hours, after which the issue may temporarily subside. In every case, I must use the 12V battery reset button to restart the car, which I suspect may be clearing diagnostic codes before they can be properly recorded. Notably, the check engine light disappears after this reset, even if it was previously displayed. Given that the hybrid battery is located beneath the rear passenger seat, I am deeply concerned that if there is an underlying thermal or electrical issue, it could pose a serious or life-threatening risk to passengers. To date, no dealership or technician has been able to duplicate or permanently resolve the problem.

The windshield is damaged very easily when a small rock hits it on the road. It's been hit before the recall and the new windshield is damaged. It's a hazard especially if it can be easily cracked. I've had other vehicles that can handle small rocks on road ways. These are damages from tiny rocks. This windshield is very weak, the Crack continues to spread all over day to day.

Driving headlight output is so diminished that it is very difficult to safely drive in adverse conditions, ie., darkness, rain and oncoming vehicles. The projector lamp assembly used in this vehicle is old technology and is somewhat compounded by the use of a smoked acrylic outer lens cover assembly. I feel that safety was compromised for style and this is not acceptable. I have sent a letter to Hyundai Motors Customer Care dated Sept. 7th in this regard asking for a Hyundai sanctioned solution and authorization for selling dealer to correct situation

Car will accelerate when pressing on brakes. Once car is able to turn off, the problem does not repeat. This has occurred at least 3 times with the same car and random times while on the road. Dealership is unable to replicate the brake issue every time the car is brought in.

NHTSA #11516987

Our problem started a few months ago. At first, we thought it was just a fluke, but this issue has happened too many times to be so. The issues are, the car does not accelerate when we depress the accelerator, we see the tachometer move, but the engine is not actually accelerating. Then at times it will accelerate on it's own, while sitting at a red light, the car tries to move forward despite having our foot on the brake, it acts like we are trying to push the accelerator and the brake at the same time. Even worse, while driving, the car will go into accident-avoidance mode, even though there is nothing in front of us. There are no errors or codes populating on the dash.

While driving in stop and go traffic this morning (02/06/2023), at approximately 8:45 am, my Hyundai Elantra began accelerating on it's own. I applied the brakes and the car behaved as though I slammed on the brakes. The acceleration and braking issues happened multiple times during this drive. After the first incident, I shifted the car into neutral, (when it happened subsequently) until it quit accelerating, which was a couple of seconds. I have scheduled service at the Hyundai dealer for tomorrow morning (02/27/2023)

My vehicle was slowing down and was halfway into a parking spot. Then, it suddenly accelerated, jumped over commercial parking blocks, and ended up stopping after hitting a wall. My brake was not working at that moment. I initially reported it to Hyundai USA (as a dealership doesn't seem to consider this a serious issue at all), but decided not to let them investigate on their end based on their slow and unprofessional responses.

I am filing a complaint regarding a safety recall repair for my vehicle that is not being handled in a timely or reasonable manner by an authorized dealership Delray Hyundai 655 NE Sixth Ave, Delray Beach. Vehicle Information: 2021 Hyundai Elantra SE VIN: [XXX] Recall Information: NHTSA Recall #24V879000 Recall #271 – Backup Camera Inspection/Replacement This recall involves a failure of the backup camera system, which directly impacts visibility while reversing and poses a safety risk. The manufacturer has indicated that a remedy is available; however, the dealership I contacted is refusing to perform recall repairs on weekends and is only offering an appointment more than a month out (scheduled for May 4th). Given that this is a safety-related recall affecting rear visibility, this delay is unreasonable and places me at continued risk while operating the vehicle. I rely on my vehicle daily and should not be required to wait an extended period for a safety recall repair that is already available. Additionally, limiting recall repairs to weekday-only appointments creates an unnecessary barrier for consumers who work standard business hours. I am requesting that this issue be reviewed, and that appropriate action be taken to ensure dealerships are providing timely access to safety recall repairs, especially when the defect impacts vehicle safety.

My vehicle has been in the shop here at McGrath Hyundai in Chicago, IL 30+ times since I bought it 5/21. Electrical, (rear), 6 horns, 6 blower motors, multiple warranty and recalls and now my front driver seat belt. They’re refusing to fix it even though I have reported it before. They’re saying over 60,000 miles makes it no longer under warranty. I reported it before and they said that it was okay. It was not okay and still isn’t okay and they think I’m going to pay $1500 to get it fixed now as well as re wiring the back of the vehicle for $600, which I have been reporting issues with for years.

NHTSA #11717820

I bought my car at McGrath Hyundai in chicago in May 2021. It’s been in their shop 30 plus times for various and repeated issues. As of late, over the last 6 months, I have reported to them and to Hyundai, my drivers side seat belt won’t retract properly and the high mounted brake light warning continuously goes off, a dinging, stating that there is an issue. Hyundai and McGrath repeatedly misdiagnosed and refused to fix these issues when they were first brought to their attention when under 60,000 miles. NOW that the car is over 60,000 miles, conveniently they’re stating that it’s out of warranty and will cost $2k. The technicians and service advisor Christine Tonelli at McGrath, knowingly and willfully misdiagnosed my car, attempting to cover up the issues stating that there was no issue. They said the seat belt was fine and the wiring wasn’t the issue for the high mount d brake light and kept changing the bulb. They knew it should have known there was a seat belt issue with it not retracting and the same with the high mount d brake light. Suddenly after 60,000 miles, they now state I was right the whole time by telling me it will be $2000 to fix it. I have all service records and emails.

The Horn never worked since I bought it in August 2023, i’ve been in a countless near accident situations where I was rendered helpless. I’ve had several instances where I get locked out of my car because the vehicle would not read the key. I tried fix the issue because I assumed it was a dead car or key battery but the same problems kept happening shortly after. I became aware of the issue with the horn not working, when I recently purchased the vehicle. I tried to contact the ALM dealership salesman to report the issue and they told me he had recently quit. They mentioned bringing it back to the shop but it wasn’t guaranteed that the issue would be fixed.

Check Hybrid System alarmed in heavy traffic and derated my car and put me in a very dangerous situation.

NHTSA #11671060

How are you? The problem with our Hyundai involves the engine and engine control system. My vehicle is equipped with the same 2.0-liter Nu GDI engine that Hyundai recalled in other 2021 and 2022 vehicles for engine stalling, internal engine damage, and fire risk. Although my VIN is not currently listed, the engine itself is identical to the recalled engines and is available for inspection. Since early ownership, the vehicle has repeatedly hesitated, surged, and jumped when accelerating from a stop, especially at stoplights and intersections. This unpredictable behavior creates a clear safety risk because the vehicle does not respond consistently in traffic and increases the risk of a collision. These issues are ongoing and reproducible under normal driving conditions. The symptoms have occurred many times and were not isolated events. The vehicle has been presented for service and the issues described. No misuse or maintenance-related cause has been identified. Prior to and during these events, the vehicle has shown reduced power, inconsistent throttle response, and hesitation. At times, warning lights and engine behavior consistent with internal engine distress have appeared. These symptoms match those described by Hyundai, Consumer Reports, and NHTSA in recalls involving this same engine. Hyundai has already acknowledged that this engine defect can lead to stalling, seizure, oil leaks, and fire, and that warning systems may not fully detect the problem until damage has already begun. Because my vehicle uses the same recalled engine and exhibits the same failure characteristics, I believe it should be reviewed as part of a recall expansion or defect investigation.

High Beam Assist, Check Rear Cross-Traffic Safety System, Check Blind-spot safety system, Check forward safety system, Check Lane Keep Assist System, Traction Control disabled.

Unintended acceleration is happening. After about 15-30 minutes of driving, accelerating from a stopped position becomes very difficult in the sense that the vehicle does NOT accelerate when gas pedal is pressed. This can be extremely dangerous as you do not know when the vehicle will no longer accelerate and could get hit when crossing an intersection or turning onto any road at all. ESC warning light came on today and vehicle will no longer start but goes into auxiliary mode. This is not the first time, second, third, nor even 5th time a report on this vehicle has been made and with each report more issues are arising with seemingly NO fix in sight.

Rear backup camera suddenly stopped working and when in reverse the sensors kick in and breaks the vehicle when there's no object or vehicle behind. Also the code for the backup sensor came up but dealer didn't do anything.

NHTSA #11604198

I owned a 2021 Hyundai Elantra N Line that experienced a recurring transmission issue. In warm weather conditions the transmission would intermittently slip and stutter, causing a jerky engagement when attempting to accelerate. In cold weather the vehicle operated normally without these symptoms. When the issue occurred, the vehicle would sometimes hesitate or fail to move forward smoothly when pressing the accelerator. This created unsafe driving situations, particularly when pulling into traffic or accelerating from a stop. On multiple occasions this behavior nearly resulted in rear-end collisions because the vehicle did not respond reliably to throttle input. The issue appeared to be temperature related, as the problem consistently occurred during warmer weather while the vehicle operated normally in colder conditions. Because the vehicle could fail to accelerate predictably, this created a safety hazard for myself and other drivers. I believe this may indicate a potential defect in the transmission system.

My car has two warning lights on my dashboard. First one is Check Foward Safety system. Second one is Check Smart Cruise Control System. Both of them turned on when I was driving in the middle of a highway. These warning lights activated out of the blue, without any unusual circumstances.I cannot use my smart cruise control system and the car is not able to alert me about forward collision. This issue has already been addressed through a recall for my vehicle's model and year in Korea. My vehicle was produced in Korea and was imported to the United States; however, Hyundai has not issued a recall regarding the same problem in the United States. This is a safety concern, and Hyundai should repair it free of charge, and the company should compensate customers who have already undergone repairs for the repair costs.

NHTSA #11596221

I was driving on the Highway at the posted speed limit when the warning "Check Forward Safety System" came up and remained on my dashboard. The cruise control stopped working also. The light remained on even after stopping and starting the car and has remained on ever since. I have never been in an accident nor has my computer system reported any collision. My Hyundai Blue Link app gives me the following DTC: C162078. It started on [XXX]. My collision detection system does not appear to be working at all and my cruise control no longer works. I'm very concerned about it malfunctioning based on other entries on the nhtsa.gov website. I took the car to Hyundai Service Center and they are trying to convince me this is due to a collision and warranty will not be covering it. They tried to charge me for diagnostic even though I already had the error code on the Hyundai BlueLink App. They confirmed that my computer has zero reports of any collisions. The service tech said, and I'm quoting, "The system is very sensitive and a swift kick could cause it to malfunction." That sounds like a manufacturing defect to me. I have never been in an accident with this car, there is zero visible damage to the front bumper, and my computer has no report of an accident. The dealership urged me to contact insurance. My Major Insurance Company told me this was absurd, would never be approved, and is clearly mechanical. They also mentioned anecdotally that this problem has been coming up a lot for them with modern Hyundai models. Then I called Hyundai Corporate and they have escalated the issue, agree it sounds mechanical, and will be contacting me in 3-5 business days. They apologized profusely so I am still holding out hope for warranty coverage. I believe the dealership is trying to blame me for this mechanical failure to avoid expense on their end.

When driving at 55MPH with cruise control on, the car suddenly accelerated to 75MPH, this happened on the open road and was able to keep under control. Auto has less than 10,000 miles. I will be contacting Hyundai customer service for a case number on this incident. First indication of a problem was cruise control, auto braking failed iin June of 2023. This follows a replacement of defective front radar unit by Hyundai which was replaced at 8295 miles on July 26, 2023. This problem first occurred in late June/early July of 2023. There was no warning.

I keep getting intermittent HEV warnings and 12-volt light. The engine then shuts down and I have no power. This has occurred several times while on the highway and this creates a safety hazard. I have been fortunate enough that this happened while I was close to the shoulder, otherwise, it could have been critical. - The failed component(s) are the 12 volt battery and engine shutdown - With the vehicle being without power while on the highway puts other drivers and myself at risk of an accident - I have taken the vehicle to two different Hyundai dealers and they have not resolved the problem - The issue was escalated to the manufacturer Hyundai Motors and they have not resolved this issue. - The 12v battery light and an HEV warning light comes on and then the engine shuts off - This issue has been happening intermittently for the past year and I first notice it on October of 2022

The horn stops working. It is not a fuse related issue. It is the horn itself. There are multiple reports of horn failure in this model, 2021 and 2022, on the internet and social media. There are people reporting that dealerships are also seeing a lot of cars with horn failure. This is a serious safety issue. Someone could go off the road into the woods and crash, unable to signal with a horn that they’re there. Unable to beep their horn to get the attention of a child or animal that is about to run into the road. There are countless scenarios where the horn is important. Cellphones don’t work everywhere… a horn should always work. There are far too many reports of the horn issue for it to not be a manufacture related issue. Please look into this. This could have pretty tragic implications that could otherwise be avoided. I will attach a screenshot from a social media Hyundai group of the 2022 model. I need to get into the dealership to have mine repaired and will do so asap. I’m just very concerned about the safety of everyone. Some are reporting dealerships are not clear about if the horn issue, which involves replacement of the steering assembly, is covered, while others are saying it is.

On three occasions while turning out into an intersection my steering wheel will lock up and my forward collision warning system will engage and my just stop in the road. Out of those three times, my car has been towed to the dealership twice. The dealer has been working very hard to identify the issue while working with Hyundai tech services. They have poured countless hours and money into this car and still have not been able to identify and correct it. My vehicle has become a deathtrap waiting to happen.

So the car will come to a dead stop. Then when I give gas, it will not go for 1-2 sec, then all of a sudden it go at high speed by itself. Even when I brake, it will feel like as if I have stepped onto gas. Very dangerous

On a few occasions (3?) the cars’ automatic emergency braking feature activated while driving at both highway and normal speeds. On none of the occasions was there inclement weather or a “slick” condition on the road. The feature would activate, give a visual and audible warning, and then de-activate within a few seconds. When the feature activated, I felt the car jerk a bit to slow down, and sort of swerve in one direction before righting itself. There is a possibility that the feature activated because I had manually enabled the Auto Hold feature as well which I usually do.

Significant water leak which I believe is due to a failure in the door seals. My personal safety is at risk due to a mold issue. The problem has been reproduced and confirmed by the Hyundai dealership’s service department (multiple visits). This problem is well documented by many individuals in the Hyundai Forums site. The results were the dealership pushes the vehicle back at the consumer without it being corrected. Problem has been occurring since purchased. I recognized the issue in early 2023

I completed an oil change at Greggs oil express in Porterville California on 02-11-2023. I have the invoice. On 02-24-2023, I went out of town. At approximately, 5:00 pm, I heard a loud bang, large amount of oil pouring out of the bottom of the car, the car became disabled and I pulled over to the side of the road. I had it towed to the closest Hyundai dealership in Victorville Ca. They provided me with a report that stated when receiving my oil change stating due to the drain plug issue is a direct result of a third party and was not covered under warranty. I then made contact with my insurance, an investigator also reported the same. I have both reports. I have made contact with Greggs Express where I received the oil change and it was suggested to report the incident as they have come across situations like this with the particular vehicle. Therefore, I am now stuck. It is not covered under warranty, not covered under insurance, and the cost is 10,000. Besides the fact that I could have been injured.

I picked up my Hyundai Elantra n-line today 12/1/22. My car was at the dealership for almost 3 weeks for transmission judder (shudder?) issues and they claim to have fixed the issue with a TSB (Technical Service Bulletin) from Hyundai with some snap and cable and additional work that was not disclosed. After picking it up and driving only 3 blocks my car went berserk where all dummy lights went on, the car's engine revved to redline, took off and suddenly the front wheels turned left (due to the avoidance features of the car perhaps) and I was able to pull the emergency break and stop the car. The car stopped luckily and if the e-brake did not work I would have ended up hitting the rear corner of a car and into a house. While the car was stopped, it was still on (unable to be turned off), all lights blinking including dummy lights and the car was showing still in DRIVE mode even though the revving stopped and the car was dead stop. After 10 minutes I was able to turn the car off (push button). Dealership dispatched a tow truck and now my car is back at the dealership for investigation. NOTE: TSB is something that is a known issue from Hyundai but not yet to the level of an official recall is what I was told by the dealership.

Hello everyone. I NEED HELP i have a 2021 hyundai elantra and i have had the same issue for over 10k+ miles and 6 months. My traction control light, (no matter what speed or acceleration/deceleration.) will flicker on and off, make a horrible noise almost as if the ABS is applying but no ABS light comes on, and the pedals will go stiff and the whole car jerks. My 2021 elantra has had a new transmission put into it AND when that didn’t fix the issue, the wheel speed sensor was replace… well if that had fixed the issue, i wouldn’t be writing this post. after a new transmission, and wheel speed sensors, didn’t fix the issue the dealership themselves advised me to look into the lemon law being they had no idea at this point what was going on with my car. i have attempted getting my car bought back under the lemon law (Ohio) which my car meets the qualifications being that the issue was brought the the dealerships attention, before the 12 month or 18k (whichever came first) which in this case was taken to them before both. and that my car had been in the shop more then 30 days cumulative (it’s been 41) and hyundai has denied my request for a buy back, and has told me i need to do more research or get an exterior 2nd opinion. (pretty much a lawyer). they’ve advised me to “just keep taking it to the shop and get it fixed”. the issue is, this does not occur all the time. it is completely random and will do it once in a week and then not again for another 3. but when this happens, it’s scary. it’s loud, the pedals go stiff and the whole car jerks. accelerating or decelerating. the dealership will not replace something if they cannot duplicate the issue which is also a reason it’s taken so long to get any sort of answers. i have multiple videos, the service MANAGER, has rode in my car with me while this issue has occurred and stated himself my vehicle is unsafe, and i should not be driving it. i need help!

Ongoing issues whereby when accelerating the car jerks due to the transmission shuddering. There are many times when acceleration is very slow and the gears slowly shift. Brought this up to the dealership where I bought the car and they keep giving me the run around.

The car was brought back to the dealership after a few months after noticing that the steering wheel would shake and the car would jerk when brake was applied to slow down. In normal street driving as well as during highway driving. The dealership since it was under the warranty replaced the front rotors and the brake pads to solve the issue. Within the one year of purchase of the car, it was once again having the same issues of steering wheel shaking and the car jerking motion back and forth. When he car was brought back to the dealership they said that it was not under the warranty and that they would not address the issue And that if i wanted it to be fixed i would have to pay out of pocket I think that there is something wrong with either the rotors or the braking system that is casing this shaking and the car jerking when trying to slow down, and it should be addressed and investigated further.

On February 23, 2022, I was involved in an accident with the Hyundai Elantra, Vin# [XXX]. The vehicle’s brakes failed, and I struck a Blue Ford Escape from behind with a speed of approximately 37 mph. On January 13th, I made an appointment with the Napleton Valley Dealership in Aurora, IL. where the vehicle was purchased complaining about the brakes and drifting into an intersection on Route 83 and Sycamore Rd. for 20 feet. The mechanic checked the brake pads, drove it for 3 miles and deemed that the vehicle’s pads were adequate. It was determined that no problem was found, brakes checked good, all within specs. (12,818 miles). The vehicle was towed from Hinsdale, IL. to Dekalb, IL., approximately 85 miles to my residence at 612 Magnolia St. Dekalb, IL. 60115. It was then towed a distance 3.2 mile to Dekalb Body and Collision, 116 Industrial Dr., Dekalb, IL. 60115. Since then, it has been back in the dealership for issues related to the engine, taillight, and a series of additional Inspections verifying that the codes were working. On March 8th when I visited the Body Shop & Collision I was told to “hire an attorney”. The vehicle was defective and should have never been on the streets. Preliminary findings on vehicle were concerning as far as airbag sensor was impacted but no airbags deployed at the time of impact. Upon vehicle arriving at our repair facility, we conducted pre-repair scan vehicle codes read as followed (see picture). Impact sensor was highly damaged, expected to have had airbags deployed at the time vehicle was impacted. Vehicle received front-end damages which resulted in needing the following parts replaced, front bumper and grille. Crash impacted the front bumper reinforcement resulting in some hours needed on frame machine to align front-end. Engine cooling system was impacted resulting in the need to replace radiator assembly and A/C condenser assembly. Hood and both front lamps are needed to be replaced as well.

The headlights and back lights turn off at random times when the headlights are on the automatic setting. This problem happens very frequently at night, putting my family at risk when the lights go off and cannot see what is ahead of us. In addition to a cop pulling me over for not having my lights on and he asked me if I was playing with the lights since they were going on and off and luckily the cop did not give me a ticket when I explained and he saw the problem (he advised me to get on this website and to make a report). I have reported this problem to the Hyundai dealership for the past 3 years and I don’t even think they take the time to investigate. The dealership just keeps telling me that with another update in the software is going to get fixed. But that is not the case. This is a very dangerous problem that is going to get someone killed. Need to be fixed

A bunch of warning signs will go off and the wheel locks. The brake system has also locked up. I captured it on video, but it won’t let me upload it here.

In the middle of crossing the Verrazzano Narrows Bridge in New York City, the forward collision warning came on and the braking system automatically engaged REPEATEDLY. I was traveling about 30 MPH and had about 4 car lengths between my car and the one in front. The system kept engaging no matter how much room I put between myself and the car in front of me, and as I was in the middle lane of a bridge in heavy traffic I could not pull over. I always keep a good distance in front when driving, but because of the system inappropriately engaging I almost got rear-ended about four times. I was terrified and this continued to happen until I got off the bridge. I use my car mainly on the weekend, and also travel this bridge almost every weekend and this was the first time this happened but it was terrifying and EXTREMELY DANGEROUS!!!!
