2019 Chevrolet Blazer: Recalls, Complaints & California Lemon Law

I was driving into a parking lot when my back passenger side window imploded like a rock was thrown at it, but no rock and nobody in sight. I looked all around for a cause but believe it somehow spontaneous shattered. Thankfully 3 minutes prior I had dropped my kids at school otherwise there would have been injury I am sure.

I believe my thermostat is a problem. I keep getting "P012B" "coolant under operating temperature" codes on my obd2 meter. This seems to coincide with "driver assist reduced" on my instrument cluster on my dash board. I researched it and on a forum it sounds to be a very common problem. Someone said to report it on here. I can clear the "p012b" error code with my obd2 and my thermostat instantly becomes responsive however it comes back within 2 days or so.

I am currently receiving a shift to park message displayed while my vehicle has been put in park and after I turn the vehicle off. While the message is displayed, the doors will not lock and a bell will not stop dinging, notifying me of the error. I have to start the vehicle, shift into gear, shift into park, and turn off several times before the error disappears. I have an appointment to have the dealer look at it this week.

NHTSA #11681906

The well known Shift to Park issue where the park sensor is off and my vehicle won’t shut off without being able to register it’s in park. Auto garage quoted $600+ to replace the entire shift assembly. There’s a service bulletin out for this issue and the specific 2019 blazer but no recall

I keep getting a message "Action Required. Steering assist is reduced. Drive with care." The code I get is P0128. I hear this is a common problem and I think GM needs to recall this problem.

NHTSA #11653713

Shift to Park issue: Known issue where the car fails to recognize it is in Park, preventing it from shutting off. Electronics: Potential blanked-out display screens, USB port issues, and malfunctioning cameras. Steering Assist: Restricted, temperature gauge goes to cold and radiator fan blows hard. I have to unplug negative cable to battery and reconnect and everything goes back to normal.

NHTSA #11729329

The shift-to-park sensor in my 2019 Chevy Blazer RS is malfunctioning. After shifting into park, the vehicle does not detect that it is in park and displays a “Shift to Park” message. The issue is/has been ongoing and now it is almost impossible to bypass with wiggling the shifter. Safety Risk: The vehicle cannot be fully shut off or locked, increasing the risk of battery drain or unintended movement. This poses a safety risk if the vehicle is left in public or on an incline. Inspection History: The vehicle was taken in to the dealership in November/December 2025 due to MULTIPLE Warning Lights: “Shift to Park”, "Steering Assist", "Stabilink" and the usb-C charging port under the radio screen will stop working all together when this happens as well. This started around September 2025 and has occurred regularly since.

NHTSA #11716876

Steering assist reduction from coolant temperature reading malfunction. Power steering reduction risking potential loss of control of vehicle. Code confirmed by Chevy dealer.

NHTSA #11651947

2019 Chevy Blazer. Car would not turn off the electrical components when parked. Put car in park and walked away and there is a warning note that says, "Shift to Park." But the car was in park. Called Chevy and they know about the issue on the 2019-2023 vehicles. They sent me the Technical Service Bulletin. Back in 2020, the car had the shifting harness and button replaced and we just had to have it replaced again because it is a consistent issue with the vehicle. Except this time, the dealer charged us $668.40 to fix it! It is a known issue by the company and THEY sent me the service bulletin to get it fixed. It should have been covered by Chevy, or, at least a recall should be instituted. The power to the car wouldn't shut off. We were able to jump the car to get it started again.

NHTSA #11726346

coolant temp gauge stuck on cold, AC quits blowing cold air, reads the thermostat code when check engine light comes on. Was told my car needs a new thermostat and a coolant temp sensor. This has proven to be a common issue among Blazers. there is no rhyme or reason when this happens and will fix itself after a while, but then happens again.

NHTSA #11665803

I leased this car October 2019 and I had to tow the car to the dealership on December 12, 2019 for an electrical issue, as the car would not start. In June 2023 with 35,700 miles, I was driving the car when an error messages flashed on the dashboard. First message was to put the car in shift/neutral and immediately I was unable to move the shifter, the break got hard under my foot and the car "STOPPED IN THE MIDDLE OF THE ROAD". Then it kept flashing the following messages "SERVICE ESC" and "INFORMATION - ALL WHEEL DRIVE OFF" and the starter light remained "GREEN". I towed the car to the dealership, however, it took them a week to check the car and as a result the battery died and they missed the "Error Messages and CODES". Without the accurate codes, I was told I had to replace the battery and starter. When I picked up the car the air condition wasn't working, so I had to replace the compressor!!! I was very afraid to drive the car and I had it parked at home for some time. My husband and friends kept encouraging me to drive it etc. Eventually, I gave in and I started to drive the car, but still stressed and afraid and praying the car will not shut off again. The trauma of the car stopping so suddenly in the middle of the road and there was nothing I could have done - is very SCARY. I am just thankful that I was not on a highway when this happened - I could have been killed. However, I decided to drive the car and I now have 38,119 miles on the car. I had to take it to the dealership again on October 24, 2023, as when I park the car, although the shifter is in Park, the dashboard is telling me to put in in park and the Starter button will not turn off. I was advised by the dealership that I need to change the "Shifter Assembly" No one can tell me why the car stopped while driving in the middle of the road and I do not feel safe in this car anymore. I am just changing all the parts in this car one by one!!!

NHTSA #11552586

Electronically controlled thermostat and sensor fail or get stuck at a much lower coolant temperature causing the dash to display the “steering assist is reduced drive with care.” It isn’t just a message, the steering is much harder to use potentially causing an accident. The ac completely doesn’t work causing potential for sensitive, elderly, or young children and pets to overheat inside, it’s significant risk of injury or death from the hot summer temperatures. The engine coolant temperature gauge is all the way down on C position which isn’t registering how hot/cold the engine gets potentially causing damage to the vehicle and a total loss of the vehicle entirely due to damage from the engine overheating. GM sent out letters to 2021 blazer owners which included a special coverage number N252508350 applying to people with this year having this problem and they have until 2036 or 150,009 mi to get the repairs made free of charge, they just bring the document with the special repair codes to the dealer and they fix it free of charge. After doing research online, this problem is affecting all years of the 2019+ blazers with the 3.6L V6 engine AND other known problems with other models and years of their other lineup of cars, it’s very widespread across their platforms. So what are people supposed to do when it isn’t the 2021 year? Pay an $800+ repair bill to GM when they KNOW it’s more widespread than just this year/make? This is a scam. I can’t even do the repair myself because I’m having trouble finding the correct parts online and not only that the repair is extensive, the whole top half of the engine needs to be taken apart just to get to the thermostat, we’re talking the airbox and intake manifold, all the plastic parts and shrouds and sensors covering engine, the fuel rail and injectors, pipes and clamps, engine coolant needs drained and refilled. It’s a major fix. I’m reporting this complaint to raise awareness and hopefully GM will do the right thing.

NHTSA #11739939

I keep getting this message that pops up, "Steering Assist reduced Drive with Care". At the same time this happens the temp gauge stays on cold, the ac quits working, the engine fan is on high, and most of the time I get code PO128. We have had it in to the dealer and they said the its the thermostat or the temp sensor. From what I am reading it could be a factory issue with the EMI issue from sensitive ECT circuitry. This has been an ongoing issue for us for over a year.

NHTSA #11683213

My vehicle was diagnosed with a faulty thermostat, specifically that the thermostat was sticking and needs replaced. My vehicle is at approximately 59,150 miles as of 12/27/2023. Prior to the diagnosis of the faulty thermostat, I intermittently received a warning message "Steering assist reduced - drive with caution", the thermostatic fan would run at full speed, and the P0128 check engine code was illuminated. These symptoms began approximately at the beginning of December 2023. The problem was confirmed by a certified GM dealership service department.

NHTSA #11562064

Engine temperature gauge is not working. Dash is displaying driver assist issue and steering intermittently locks up while moving. Air conditioning does not work and cooling fan is running at high speed. Thermostat and coolant temperature sensor need to be replaced. Such a high number of these vehicles are failing that i can’t even get factory parts

NHTSA #11694417

Was getting a steering assist reduced error code. Auto stop quit functioning and air conditioning stopped cooling. Engine sounded like a jet. P 0128 thermostat error code came up and had to be replaced. I see lots of similar complaints. Cost me $700.

NHTSA #11711579

Temp gauge intermittently reads cold, no ac and engine cooling fan constantly blowing, dash warning re power steering, 40,000 miles, code po128, review of google indicates this is a common problem and likely needs a new thermostat and ect

Dashboard goes on like a Christmas tree (almost all lights turn on ABS GAS LIGHT TRACTION CONTROL PARKING SERVICE LIGHT) check engine stays on then disappears after a few days. Transmission won’t gear into shifts only stays in one shift.

NHTSA #11690844

At startup, I would receive a message that said, steering assist reduced. There were no check engine lights or warning lights. My air conditioning stopped working, and my temperature gauge on the dash remained at cold. I also noticed the radiator fans were on full blast, continuously. I called the dealer, and they weren't sure what was causing that. I told them I was getting codes #U0401 & P0128. They asked me to clear the codes to see if they returned. I cleared the codes, but they returned immediately on restart of the engine. I'm going to replace the thermostat but i didn't understand the #U0401 code, so did further research. I found 2017 Bulletin #17-NA-158 which seamed relevent to my issues, and Vehicle Fitment that confirmed my 2019 Chevy Blazer is included. I then came to find that the un-shielded low voltage wires for the coolant temperature sensor are routed through the same harness as high voltage coil wiring. Some of us know that EMI will affect low voltage signals. As an HVAC system designer, I know that un-shielded low voltage communication wiring cannot run parallel two line voltage power wiring. The effects are not continuous, but definitely reoccurring. I also understand there has not been a recall for this issue which surprises me. I can replace the thermostat even in its difficult position, but I don't feel comfortable in separating the low voltage wiring from the harness. I understand that dealers who are aware of this issue, charge a hefty fee to do so. It's definitely one that I can't afford.

NHTSA #11666997

I cannot shut off my vehicle. When I turn off engine warning message and alert binging tells me to shift to park. The vehicle is in park but vehicle does not register that it’s in park. I’m stuck in vehicle which will not stop alerts and runs down battery. This is a hazardous situation. I can’t tell if car is actually engaged in park or not. This started happening intermittently over the last month but now it happens 8 times out of 10 when I try to shut off the vehicle.

The Blazer is having a recurring P0128 code. We have informed the dealership. This has been going on for 2 years or so. I reset the code with a code reader and it stays off for a few months usually. Tried to have the dealership look at it one of the last times it happened but they wouldn't just look at it...they wanted to set up an appointment. We needed the car so I reset the code again. Now it is time to get it fixed. I know it needs a thermostat and temperature sensor. The cost to install it will be close to $1000. This should not be at my cost. This is a know issue with the 3.6L engine and it affects the emissions of the vehicle along with many other parts of the engine. I am reaching out to see what can be done.

NHTSA #11657094

Received repeated message on display " steering assist reduced, drive with care" Engine races at times and Auto Stop quicks working. Could lead to a crash if steering is restricted due to P0128 code was repeatedly triggered as a fault code. Turned out to be thermostat which is being replaced on thousands of these vehicles. You can search for the message. GM is replacing under powertrain warranty however many vehicles are beyond warranty. This is approximately a $1000 repair.

Hi My wife arrived home from work and put the truck in park. A message came up on the instrument panel saying shift to park and would not let her shut the vehicle off. I went out could not figure out what was going on because the truck was clearly in park. After moving the gear shift around the message went away and I was able to shut off the truck. A couple of days later when she got to work, it did it again. Moving the gear shift around turned it off. I took the truck to the dealer 10/18/23 and inquired about a recall for this because so many people are having the same issue, on several GM makes. No recall and I had to pay close to $572.99 for them to replace the gear shift assembly. We just bought the truck in Feb of 23 and paid cash. $30.000. At time of purchase the truck had 21000 miles. Today it has only 24000.

When Driving the vehicle, usually around 1500 rpm, you feel the transmission start to stutter, and during this stuttering, the whole car shakes violently. this violent shaking occurs on the highway with speeds of 70mph and over. the shaking causes the steering wheel and lane centering function to become disoriented, hence almost causing me to get into an accident on the highway. This is not an isolated incident for my vehicle only. I am in a chevy 2019 blazer group on facebook and dozens of members have experienced this same exact issue. the members that got it repaired had to have the entire transmission replaced. apparently it is an issue with the gears not fitting properly and grinding causing shavings to get into the the transmission fluid causing the danger. I have addressed this issue with the chevy dealership i bought it from but the refused to document it or take accountability for the issue.

NHTSA #11510721

The vehicle will not shut off when you shift to park. You are forced to sit in the vehicle for extended periods of time attempting to get the vehicle turned off. Apparently Chevy is familiar with eat problem and there are pending class action law suits in Ohio. According to the dealership Chevy has acknowledged there is a defect but no recall has been issued. We have had this issue for about two months and it is getting worse.

NHTSA #11730819

"shift to park" message appears when parked (even if safety brake is engaged) and attempting to turn off the vehicle. The vehicle does not turn off and remains running for various periods of time. Unable to turn the vehicle off, leaving it unsecure and drains the battery. This happens consistently. I contacted my local dealership and they confirmed getting several of these reports through their shop, but no recall has been made.

My 2019 Blazer gave a Steering Assist warning on 2 Nov 2024. I was aware of a recall for other Blazers but for some reason my VIN was not among those recalled. I took it to the dealership on 6 Nov 2024. The dealership has determined that the issue is indeed the same issue with those other Blazers that have been recalled but refuses to include my car in the recall because the VIN number wasn't originally among that recall. I was told that the car needed anew temperature gage and that they would have to order it, however, the component was available outside of the dealership. I paid for the diagnostics and the part, being told that the light(s) would stay on, I would still be able to drive it and that I would receive a call when the part came in. It is my understanding that the steering assist reduced can affect the power steering and essentially revert back to manual power steering, potentially causing a loss of control while driving and increasing the risk of accidents. There were no warnings of the steering failure assist warning. It just appeared on Nov 2, 2024 at 1130am. About 1240pm I noticed that the temp gage was inop and the check engine light was now illuminated. I contend that because GM has already identified the thermostat issue serious enough to do a recall, then all Blazers with that recall issue, VIN number aside, should be given the same consideration and not have to pay for something that GM has already taken responsibility for. The dealership however does not agree for the simple fact that the VIN was not identified in the original recall.

NHTSA #11623882

When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of ‘Shift to Park’ appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. This currently is forcing me to restart the engine, put my car in reverse, shift back in drive, try re-parking and turning it off again, repeating the process until it eventually turns off. I do not know if my car is truly in gear or not. I’m afraid that it might cause a dangerous situation. GM has already identified this recall for other VINs of 2019 Chevy Blazers I believe it should be extended to additional VINs.

NHTSA #11630498

Shift to park has came on the dash. Can not shut the car off. This will mean I will have to unplug the battery and not be able to lock the car. This is the first that it has occurred. Will have to schedule an appointment with the dealership on Monday.

I bought a 2019 Chevy Blazer in February 2023 . The vehicle has issues when I fill it with gas. As soon as I gas up to full it starts jerking immediately afterwards. It makes loud popping sounds. The engine dies completely. It starts to tremble and will not go. When I try to turn in back on , the starter works very hard before it will turn back on. It does turn back on eventually but I have to pull over to the side and accelerate the engine until it finally stays on. I drives that way turning off at lights and stops. After about 10-15 minutes of this , it finally stays on long enough to drive another 20 minutes or so to get home. After it rests for a few hours, it goes like normal. This is a big safety concern for me since these episodes happen every week when I fill up my car with gas. I have almost been hit from behind during these episodes and it is very scary and such a hassle to have to deal with this every week. I have already had several Chevy dealers and mechanics work on this problem and it continues to act up like this. I have all the paperwork for the work that has been done. $15, 000 have already been spent on this problem and the problem still continues. Please help me. I like chevy vehicles and have always bought chevy but this is the second chevy vehicle that has given me problems when I gas up. Please look into this problem.

engine - code p0128 engine coolant thermostat. This is a safety issue because it reduces the power steering on vehicle, auto stop stopped working, unable to remote start vehicle. Issue has been confirmed at an independent service center (I work at an auto collision center). Warning lamp - check engine light. Message on dash - power steering reduced. Appears everything came on at the same time. Per dealership items most likely needing replacement are engine coolant thermostat and engine coolant temperature sensor but ecm module could also need replacement. Advised common problem but no recall power train - transmission shutters when accelerating. Safety is at risk because vehicle will not accelerate or accelerate too quickly. Called to dealership advise flush transmission fluid twice to fix issue. We have done this 4 times in the past year. Shutter temporarily reduces but does not go away. Per service advisor it is a "function design" and if flushing transmission fluid does not fix issue then transmission will need to be replaced. There are no warning lights or messages on dash electrical - vehicle says shift to park when vehicle is in park and will not allow vehicle to turn off. It is a safety issue because vehicle will not shut off. Problem confirmed by an independent service center we have already replaced the in-line wire harness jumper. This did not fix the issue. Advised from service center that entire shifter would need to be replaced.

NHTSA #11656851

Consistent Blazer issue. Error coded “steering assist reduced. Please drive with care”. There is a thermostat issue. Causing the car to sputter and not run properly. This a common issue with Blazers and a manufacturer default. Should be recalled and covered. It is a safety issue.

NHTSA #11649173

Nothing necessarily happened, but I've been getting the "steering assist reduced, drive with care" pop up, which assist I've been reading might mean a faulty thermostat. Sounds like a common issue and may e time for a recall? Only 60k miles on my blazer.

NHTSA #11693730

When attempting to put my car in PARK, the car issues a warning stating the car is not in PARK, it doesn't recognize the gear shift being in park, therefore, I am unable to shut my car off or lock it up. It is a known manufacturing defect and GM refuses to cover the cost to add a bandaid to it as there is no permanent fix. This is a safety issue, and now my car is not reliable, nor safe. GM refuses to issue a recall on this.

NHTSA #11640686

When placing the vehicle into park there is often a issue with the sensor recognizing that the vehicle stating that it is not when attempting to power off the vehicle. When stopping there are times that the vehicle is difficult to stop and there is not fault code as to what may be occurring.

NHTSA #11629234

1. Wire harness with coil wires is the problem. It was fixed by a local shop and the vehicle can be inspected if needed. 2. The car throws a code for a faulty thermostat/coolant temp sensor. This will not allow the car get to oporating temp and could cause engine damage or not perform properly causing risk of an accident. Also this will reduce the driver assist features such as lane assist and adaptive cruise/braking. 3. Yes. 4. A local shop inspected the thermostat and coolant temp sensor and they oporated as they should. 5. The engine light comes on for the reasons mentioned above. It also has a "driver assist reduced" message. It appeared randomly while driving and stayed on for multiple days. Vehicle had a code for a bad thermostat/coolant temp sensor and "driver assist reduced" message. The cause is NOT the temp sensor or thermostat and is actually a wiring harness that two wires need to be separated from the bunch. The frequency from one wire interferes with the coolant temp sensor wires. I am on several forums for chevy blazers and there are TONS of posts about this issue with the 3.6 V6. Most people will go in and have these expensice parts replaced. It is not acceptable to have people get charged for a $800+ job when the part is not faulty.

NHTSA #11654938

When I am shifting my vehicle to park (gear shift in console area) and turn my vehicle off I will get an error code in my dashboard that I need to shift to park. My gear shift in the console is lite up P and my dashboard electronic system says P; but when I try to turn my car off it won't turn off and stays on again giving me the error code that need to shift to park. I then have to turn my car back on to then try and turn it off with the same error code coming on. I can try pushing the gear shift further with no success, shift to different gears back to park, and try waiting a few minutes after shifting to park before turning it off and still no success. This is a safety issue that my car is not really in park and will take off if I take my foot off the brake when this is all occurring. I at one point had to turn my vehicle on and back off with no success at least 5 times before I can finally get it to turn off. This problem has been confirmed by multiple Chevrolet dealerships with all of them saying they have seen many vehicles (same make and model with other models included) with this issue. Manufacturer knows about it.

Receiving shift to park error when attempting to shut off my vehicle. In December 2021 I had the parts replaced at the dealership, and as of a week ago the issue has started back. I am concerned that I will be stucked somewhere unable to shut off my vehicle or worst-case it doesn't actually stay in park.

Without warning, the brake pedal on my 2019 Chevy Blazer became hard, almost as if the car was turned off. I was unable to stop and slowly rolled into the back of a semi stopped at a stoplight. This was moments after exiting off of a major highway and could have been much worse. The car was taken to a mechanic and it was determined to be a failure with the brake booster. GM has issued recalls for this problem in several other models but the Blazer has been excluded. Based on online forums and complaints of multiple other Blazer owners, it seems obvious that Blazers should have been included in the recall.

The contact owns a 2019 Chevrolet Blazer. The contact stated that they began to notice the grill at the front of their vehicle begin to flake slowly over time. The flakes had grown to the size of a dime. The vehicle was taken to the local dealer, where the contact was advised that the dealer would cover half of the cost to replace the grill. The vehicle was not repaired. The manufacturer was notified of the issue.

I took my vehicle to the dealership for the recommended oil change on 09/15/2023. I am extremely good about keeping up on the routine maintenance. Upon arrival, the technician asked if I knew that my check engine light was on. I stated no, it was not on during my drive in and has not been on previously whatsoever. I scheduled a diagnostic for 09/20/2023 and brought it back to the dealership with 68,191 being the mileage. It was determined that my thermostat needs to be replaced. I then began receiving the message Steering Assist is Reduced" which is very unsettling. I am finding that a lot of newer model 2019+ Chevy Blazer owners are struggling with the exact same temperature issue, even those with way fewer mileage than mine for example a person who just had 25K on theirs. This needs to be taken more seriously / addressed further by the manufacturer.

My complaint is with the standard HID headlights in the 2019 Blazer and the very poor mounting system. The headlights are mounted TOO LOW to be effective in lighting the roadway, particularly where no shoulder stripping is on the roadway. Too, at unlighted intersections the lighting so poor that safe left or right turns cannot be accomplished. The HID lights themselves are a poor design in that they do not offer any useable peripheral lighting to add vision to the road shoulders. Due to the low mounting, the HID do not adequately shine light onto the road surface. Rather the available light shines across the surface and not down on it had the lights been mounted at the top of the fenders as most lights are mounted and designed. This has been an ongoing issue with the vehicle since purchasing the car new in November of 2018.

The front passenger seat belt was not clicking in. There was no damage done to the seat belt it just stopped working. The car is only 3 years old the seatbelt should not fail this is a safety issue. I had to pay $366 to fix it at the dealer. They said it was no longer under warranty and since there was not a recall they would not pay for it.

Initially received Stabilitrak dash warning when brakes were applied for longer than 30 seconds (ie., stop light) for several days with no SEL. Then, while driving along a secondary highway at approximately 60mph, all dash lights lit up, power steering failed, power brake assist failed, and vehicle started stumbling. Pulled to side of road and vehicle shut off. Performed restart and was able to complete drive home (approx 3 miles). Upon arrival and shutting off vehicle, all dash lights illuminated then shut off. Vehicle would not start after (no click, no turnover, indicating failed battery). Attempted to charge/maintain battery but battery charger indicated sulfated battery. Multimeter showd 7.5V. Replaced battery and car started normally but all computer functions were reset to factory defaults. The failure of the power steering and brakes due to a faulty battery is an extreme safety issue. The fact that the battery is only 3 years old and internally corroded to the point it can't be charged is both disappointing and an additional safety hazard.
