2020 Toyota Corolla: Recalls, Complaints & California Lemon Law

Coolant Bypass Valve

NHTSA #11673798

On June 19, 2025, I was driving and out of nowhere, there was a warning notification that said "A warning light was turned on. Would you like to call an operator?" On the digital cluster, there was a message that said "Engine Maintenance Required - Visit Your Dealer. Mileage noted down was 79,632. I asked around for some insight and people are telling me it's the water/coolant bypass valve that's leaking and the Op code is 24TE04R1. Will this be a covered service?

NHTSA #11668609

The engine maintenance required message appeared on the dash. I was travel from work to home (about 40 miles). I pulled over immediately at a store, left my car and walked over a mile to the mechanic shop down the road (in 95° weather with a knee that has been through 3 surgeries in less than 5 years). The gentleman took me back to my car. Followed me as i took my car back to the repair shop since it was close and did not have any lights on the dash and I was not overheating. He plugged a reader in it and the error was a coolant bypass valve issue (i can't remember the exact verbage). I purchased a replacement valve 6-17-25, along with toyota coolant. I am having to wait and save up the money to have the valve replaced at the shop got the message code from. I can not afford the dealerships cost to replace the valve. The valve and coolant was expensive in itself. I have read many forums and blogs. Toyota knew there was an issue and I am requesting my reimbursement for the cost of replacing a part you knew was faulty.

Flow Shut-off Valve Coolant Leak

NHTSA #11665916

I have an error that appeared displaying “Engine Maintenance Required” after some investigation snd research, I have noticed that this is a common issue associated with the OEM Engine Coolant Bypass Valve. This occurred as I was driving home from work when I was driving down the freeway, I did not run into any obstacles or have an accident, it appeared out of thin air.

NHTSA #11662682

unknown. i know that my car was doing fine and then randomly the coolant was low and my car was overheating on my way to work. i have yet to get it fixed, as i dont know how much it could cost me. but i read that 2020-2021 toyota makes were having issues with their coolant.

NHTSA #11661991

Car is currently at 56k miles and the "Engine maintenance required" popped up on my dashboard I'm pretty sure this is the engine coolant bypass valve which I read is a constant problem for new toyotas like mine

NHTSA #11656924

I received a "voluntary Customer Support Program" letter from Toyota saying that a small engine coolant leak can occur that "can allow coolant to drip on other parts of the vehicle. This can cause 'Engine Maintenance Required' to be displayed or cause the A/C not to function normally." Then it concludes that repair with a new "flow shut-off valve" will fix the problem, "under the terms of this Customer Support Program." I thought this was a recall and took my car in only to find that they wanted nearly $700 for the repair, because I did not have an extended warranty. When asked whether this could cause a safety problem if unfixed the reply from the Service Advisor was yes -- the coolant leak could potentially cause the engine to seize up on the highway. I was shocked that a defective part in the car I purchased new for $20,000 plus would not be replaced free of charge. I have put less than 16,000 miles on the car and now I find the resale value is essentially zero. And I now may be driving a potentially risky vehicle that could crash or leave me stranded somewhere. I feel there should be a repair at no charge.

NHTSA #11659283

I own a 2020 Toyota Corolla, and without any prior warning, the “Engine Maintenance Required” message appeared on my dashboard at approximately 79,575 miles. There were no unusual symptoms—no overheating, strange noises, or performance issues—before the light turned on. I had my vehicle inspected by Golling Toyota of Warren, where they diagnosed the issue as a faulty Engine Coolant Bypass Valve. I was informed that the valve needed to be replaced and flushed. The total cost of the repair was $932.21, which I had to pay out of pocket. Because the message specifically said “Engine Maintenance Required,” I was concerned that it could be a serious engine issue. Out of caution, I avoided driving the vehicle until it was inspected, as I didn’t know whether it could result in engine damage, performance failure, or a sudden breakdown while on the road. The fear of an unknown engine-related malfunction created a genuine safety concern for me and others —especially since the warning came without any prior symptoms. I later learned that the problem was tied to the Engine Coolant Bypass Valve, which is known to fail prematurely in Toyota vehicles. This failure can affect engine performance and temperature regulation, increasing the risk of engine damage or failure while driving. There is already a class-action lawsuit concerning this issue, yet Toyota has not issued a recall. Owners like myself are being left to pay out of pocket for a known defect that poses real safety risks. I’m submitting this complaint in hopes that Toyota will be held accountable and that the NHTSA will take appropriate action to protect consumers from this recurring and potentially dangerous defect.

NHTSA #11652732

“Engine maintenance required” alert received, related to a faulty coolant bypass valve which will need replacement. Vehicle is currently at 51,049 miles. Alert message can’t be dismissed from the dashboard. It obstructs a significant portion of the speedometer.

NHTSA #11638624

There was a maintenance required notice on my dashboard and I searched up that it was my coolant bypass valve having an issue. Apparently it’s a defective part in Toyota Corolla and rav4 models from 2019-2023 I believe. The notice would come on and off each time I would start the vehicle. The dealership has confirmed this issue is common and after having it inspected and diagnosed, it was indeed the coolant bypass valve. My safety and the safety of others were fine, my engine would’ve been the unfortunate casualty if I did not take care of this.

NHTSA #11631190

Vehicle was brought to Toyota because of "Engine Maintenance Required" message. We initially thought it was "Maintenance Required" so husband said we may need to change the oil, but it was only a few thousand miles since last oil change. I tried to remove the message but the Toyota Manual did not have any instructions on the "Engine Maintenance Required" message removal. When he left Toyota after changing oil, same message was on dashboard. Husband went back to Toyota and asked them to remove the "Engine Maintenance Required" and was told that there is a coolant bypass valve that must be changed in order for the message to go away. The cost should be around $1,000 and then proceeded to tell him he needed to buy new tires as well. All would total about $2,800. Vehicle has 58K miles and we are afraid to drive the vehicle now until we know what is actually wrong with it. It's suspicious to read all the complaints describing the same situation we have with Toyota. By the way, after we were told about the needed repair, I started getting emails from Toyota about purchasing a Toyota warranty, advertisements in the mail from car warranty companies and phone calls from Toyota salespeople to come and buy/lease a new Corolla and I would get a "great deal"! Is this some scam to generate business? Are Toyota owners being subjected to a "bait and switch" scam? I would like an investigation initiated by your agency. My vehicle is available upon request and our safety is at risk because we truly don't know what is wrong with it and afraid to drive it any longer. If your agency wants to read complaints from other owners, I direct you to read the complaints on [XXX] or Google "Toyota Engine Maintenance Repair" message. It's very much an eye-opener about fraud being perpetrated by Toyota. I can provide any documentation needed when I am personally contacted and requested to furnish them.

My 2020 toyota corolla's warning light which stated "engine maintenance required visit your dealer" came on. When I called the dealership they stated I would need to come in and hook it up to diagnose the problem which would cose me $185 + taxes and fees. Then once diagnosed they would be able to fix the problem. I checked with O'Reilly's autopart store and Autozone which both of their scanners found nothing wrong. So I informed Toyota and they stated they I need to bring it to them because their scanner/tool is the one which will tell us what the problem is specific to my car. But they stated they think it could be a hose related to my coolant system to prevent my car from overheating. They stated to watch the temperature gauge while driving as it may overheat and become dangerous to drive. If this happens or I see any smoke pull over and get out if the car. However they haven't seen anyone have to do this so they think I should be fine but I should fix this problem soon. I asked if that is the problem would it fall under my mechanical breakdown insurance coverage and the dealership stated that if that's the problem yes but if I go through the insurance it will take a really long time to fix because they'd have to file a claim and get paid before doing any repairs. Then they said I'd have to pay the copay and any difference. I was confused as my insurance states I only have to pay my copay. However, I had someone else with a scanner/tool hook theirs up and to see if we could check the actual problem and it did say the error code P268115 engine bypass coolant valve. So, this was the issue. I viewed online that there is a class action lawsuit going on right now for this same problem with 2019-2023 Toyota Rav 4 and Corolla's. Toyota failed to disclose this information to it's consumers and it is not being covered under the power train warranty either. This safety issue with cars overheating is dangerous and costly.

Engine coolant Bypass Valve issue

NHTSA #11609057

Faulty coolant bypass valve needing repair. Manufacturer has open class action lawsuit. My car is also impacted.

NHTSA #11608710

coolant bypass valve is defective and failed prematurely. coolant bypass valve cracks and leaks coolant. Once coolant beings leaking, it comes into contact with the electrical connector located near the valve. The coolant corrodes and damages the connector, which eventually causes connector to malfunction. This causes the coolant bypass valve to be stuck in the “open” or “closed” position (i.e. it no longer responds to the needs of the engine), restricting coolant flow and allowing the engine to overheat. I had to repair the vehicle at Harvey's Autotech 521 West Sixth Street Corona, CA 92882 (951) 737-9878 at the cost of $643.91and loss of a work day.

"Engine Maintenance Required See Dealer" Message on Dash Display Engine Coolant Bypass Valve I see this incident repeated for the recent Corolla SE and RAV 4 multiple times with no recall/resolution other than Toyota customers should be prepared to spend close to $750 to fix and replace this part that only takes about 20 minutes to be replaced. This is not new to Toyota. This a rip off. A lot money was paid for the car. Went to dealer less than a year ago and purchased a 2020 SE with a $23,323 price tag. Including dealer fees, finance charges and extended warranties the total price comes to $39,000+. I feel cheated as a customer. A practically new car comes with a defective part and it is not covered by warranty?? Come on. I've trusted and recommended Toyota for years. Do you no longer stand by your company name? Need a better resolution. Please.

Coolant bypass valve malfunction, leaking coolant, engine maintenance required sign pops up on dash around 60k miles

NHTSA #11603302

I keep getting a warning sign on my dashboard stating that "Engine maintenance required. Call your dealership". After scanning for codes, I get the code P2681, or that the Engine coolant bypass valve is faulty. After looking online it appears that this is a common issue with this car model. There is a class action lawsuit for this right now since the part is known to be faulty and can crack and leak engine coolant. Toyota has refused to issue a recall for this and will charge you to replace this faulty hardware. I also am not able to clear the message while driving and it will constantly pop back up distracting me while driving and making me unable to see any important warning on my dashboard. This is endangering my ability to safely drive my vehicle.

There is a problem with the bypass control heater valve of my car Corolla Toyota 2020 It says i have to replace it but it's still running good. I research what this part is about and it says that this is a malfunction in all the Toyota Corollas and RAV4 2019-2021. The message "engine maintenance required" doesn't go away and it doesn't let me see the mile percentage when driving. This problem has been confirmed by a mechanic who installed the tablet and run a test to see what's wrong with it. The car has not been checked by insurance because of this manufacturer malfunction. This all started happening 6 months ago and haven't found a way to replace it and dealership charges over 800 dollars for a mistake Toyota made on all Corollas line. Please help me find a solution. Thank you!

NHTSA #11625521

"Engine Maintenance Required - Visit Your Dealer" message popped up on my car's (Toyota Corolla 2020) dashboard all of a sudden and I didn't have any issues with engine before. I brought up my card to Toyota Service Center in Sunnyvale, CA and they told me that my car's coolant bypass valve has to be replaced and re-check if it's needed which is an uncertain thing and advised me not driving the car as it may damage the cooling system components or even the engine itself. All of these will cost me 911.58$ which is too much but it's not all yet. I was researching this issue on the Internet and figured out that many people who has the Corolla 2020 and 2021 had the exact same issue. I don't think it's a coincidence. People also complaining about the same issue for Toyota Rav4 and Toyota Camry. I don't want to pay so much money which is almost 1k. I never had any accidents and or crashes.

Service professional at the dealership stated that this is a common issue and most of the time Toyota warranty doesn’t want to repair it, also said that it should be recalled. I have also seen hundreds of people complain about this on Rav4 forums.

NHTSA #11626281

I have a 2020 Toyota Corolla. "Engine Maintenance Required; Visit Your Dealer" came on the display after I brought my car to the dealership. I returned to the dealership and was told it was $250 to diagnose the problem. I waited a month later and brought my car back for an 80,000 inspection at the Longo Toyota in Prosper Texas. They diagnosed the problem this time and said they would have to replace the Coolant Bypass Valve and Hose for ~$800 plus labor costs. The risk of not repairing these parts is possible engine failure or fire. I've seen many other discussion forums where people are experiencing the same problem with Rav4, Corolla, and Camry models 2020-2023. These parts are not covered under warranty and would have to pay out of pocket for the repairs. Toyota should issue a recall since many people are reporting these same issues, creating out-of-pocket costs for the repairs for >$800.

My son and daughter in law moved from California to Georgia due to military duties in Hinesville Georgia. They drove their 2020 Toyota Corolla from California to Georgia. They paid the fee to obtain their 2024 registration sticker but got denied by the DMV in California due to a recall on this vehicle. My son took the vehicle to Chatham Parkway Toyota in Savannah Georgia to fix the recall. He received documentation that the recall has been fixed. My daughter in law took this documentation to the DMV and they said it was not sufficient, we needed to provide the original pink copy of the recall. Chatman Parkway Toyota never gave my son the original copy. Where can we obtain this so we can receive our registration sticker? Can you please help us out and contact Chatham Parkway Toyota to see if they even fixed the recall problem or not and why they did not give my son an original copy of the fixed recall situation. It has been a struggle to obtain the registration sticker when the recall was a problem. This situation has been very stressful due to an expired registration and not being able to drive u til we receive the correct sticker. Please help if you can. Thank you, [XXX] . [XXX] .

The "Engine Maintenance Required" message on a 2020 Toyota Corolla SE keep coming on after I have reset numerous time. The "Engine Maintenance Required" message on a 2020 Toyota Corolla SE typically indicates a problem with the coolant bypass valve, not the regular maintenance schedule. This message is distinct from the "Maintenance Required" light that usually prompts oil changes. The coolant bypass valve issue often results in a DTC code and may require replacement.

Approximately one month ago the clutch pedal on my manual 2020 Corolla went all the way to the floor and stuck in place. Had it towed to my mechanics shop and it took them nearly 2 weeks just to get a slave cylinder to replace the defective part with. Fast-forward a week later and exactly the same thing happened. According to several different threads I have read online, this seems to be a problematic situation with the manual Corollas. Hopefully I will not experience any further problems however it appears that the defective slave cylinder part is to blame.

I am experiencing a recurring issue with the Data Communication Module (DCM) in my 2020 Toyota Corolla. This component was previously subject to a recall, which I addressed at a dealership. However, the problem persists, and many other Toyota owners, including those with RAV4 models, are reporting similar issues. Discussions on forums such as Toyota Nation and Toyota Owners Club highlight these ongoing concerns. My vehicle is out of warranty, and replacing the DCM is estimated to cost over $800. I have confirmed that the issue lies with the DCM system, as removing the corresponding fuse eliminates the error message on the multimedia system. However, this circuit also powers the right speaker and microphone, making it impractical to simply disconnect the module. The local dealership has quoted $205 for diagnostics, despite my prior identification of the problem. Revisiting the original dealership where the recall work was performed is not feasible, as it is located across the country. Toyota has not offered a remedy, leaving me without an affordable or practical solution to address what appears to be a manufacturer fault. I am seeking assistance and accountability for this persistent and widespread issue. Please look at the corresponding links detailing the systemic problem with the system, that other owners have experienced [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle flashes ‘connected device is not compatible’ with the ‘SOS button flashing continuously red then green.’ This message causes the microphone to remove 1 to 3 seconds of sound every 5 to 15 seconds making a clicking noise when speaking on vehicles Bluetooth. This is typically corrected by a DCM reset and firmware update. Not only is this incredibly inconvenient during normal conversation but having to repeat random portions of the conversation is irritating at best. Recently I had to make a 911 call and had to repeat myself several times to request emergency services. This glitch caused the emergency 30 second call to be extended roughly 1 1/2 to 3 minutes delaying response time. If the clicking occurs while the other person is speaking this is not noticeable. This is an identified issue only covered under basic warranty with specific TSB correction. This defect causes portions of vehicle occupants conversation to be removed and replaced with a clicking noise.

Vehicle would not start. After the vehicle's battery was jumped, the vehicle would start, but upon moving the vehicle, the dashboard message read, "Engine Stopped - Steering Power Low." There are numerous entries in online forums of others looking for solution for the same issue. Sometimes others have said that this occurred while in stop-and-go traffic on the highway or idling at a red light. Clearly, if a vehicle becomes disabled on a roadway with no prior warning of a failing battery, that is a safety issue. There was no warning of a failing battery. Battery was replaced, which was a surprise for a 2020 vehicle. However, this issue has occurred in newer vehicles as well if you review the comments in the online forums. Failed battery was tested and measured 67CCA/295CCA @11.44V. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Once I parked my car and turned on the A/C a couple mins later I received a warning message on my car screen saying “ Engine Maintenance Required Visit Your Dealer”. After having my car for 4 years I’ve never received this message till now (04/22/25). I thought it was because I needed an oil change but I was wrong because my oil is good. I checked my car and saw that the issue is the “coolant bypass valve”. I don’t even use my car that much for this to happen. I saw this is a common issue with a Toyota Corolla 2020 but the dealership does not want to fix this issue for free.

Coolant bypass valve. Becoming persistent in several models of Toyota 2019-2021. Dealerships claim it’s not covered under powertrain warranty because it’s part of the coolant system. Should be covered and customer should be compensated or reimbursed.

My airbag sensory notifications keeps coming on. When I start my car normally it isn’t on but once I start driving the notification will come on along with the ding noise it makes when you don’t have on a seat belt. I notice there was a recall on this issue for the later model Corolla and wanted to see if possibly this could be considered for the 2020 Corolla’s.

NHTSA #11674399

I contacted my local Toyota dealership a couple months ago about air bag recall situation and they’ve told me the parts are not ready yet. Then I called just a couple days ago and they said that the wait time will be next year in 2025 about march or may and I asked the person working there if I would to get in a crash and the air bags don’t deploy what would I be able to do and they said you can sue Toyota. I just think next year by March or May is along time especially if I have my wife in the car too.

The windshield wipers stop in the middle of the windshield at times when set to intermittent. Sometimes they will not shut off when they are turned off. This can be a hazard while you are driving and you never know when it will happen.

While driving with the windshield wipers on during a rain storm , the wipers would stop working suddenly. The Car was taken to dealer and windshield motor was replaced. Without working wipers, it was dangerous to drive.

NHTSA #11663778

The windshield wipers seize up. On the intermittent setting, instead of wiping every few seconds they sometimes wipe 3 times in a row and then stop in the middle of the windshield sometimes obstructing my view. They sometimes start back up on their own and sometimes are stuck there until I switch to a higher speed and lower speed for the windshield wipers. It becomes a game of trying to restart them while driving while it's raining. It's dangerous.
