2022 Toyota Corolla

The component that failed is the coolant bypass valve, which is part of the engine cooling system. The vehicle is available for inspection upon request. The issue was first indicated by an "Engine Maintenance Required" warning message that appeared on the dashboard. No prior symptoms were noticeable before the warning appeared. The warning came on suddenly during normal driving conditions. This failure poses a potential safety risk because the coolant bypass valve regulates engine temperature. If it malfunctions, it may lead to improper engine cooling, overheating, reduced engine performance, or sudden breakdown while driving. This could increase the risk of being stranded in traffic or experiencing a hazardous situation on the road. The problem has been diagnosed and confirmed by an authorized Toyota dealership, which identified the coolant bypass valve as failed and in need of replacement. The dealership provided a repair estimate of $775 prior to taxes and fees. The manager shared that it would be around $890+ after it is all calculated. The vehicle has not been involved in any accident related to this issue, but the malfunction was verified through dealer inspection. No police or insurance reports were filed, as this was a mechanical failure. Based on personal research, this appears to be a widespread issue affecting similar Toyota vehicles, including other Corollas and RAV4 models, where the same component has failed under similar conditions. In some cases, repairs have been covered by the manufacturer, indicating awareness of the issue. There are many groups on Facebook and Reddit where customers with the same make and model 2022 Toyota Corolla SE have had the same issue after 3 years of having the vehicle. In summary, while driving under normal conditions, the warning message appeared without prior indication. The dealership later confirmed that the coolant bypass valve had failed and required replacement.

Hello, on October 14th 2024 I reached out to Toyota over a “engine maintenance required” message on my dash along with a check engine light. I took it to the local toyota dealership in Downey CA. After testing the Engine coolant bypass valve B Control circuit high failed. Toyota replaced the valve on October 21st 2024. Issuing me a 1year/12,000 mile warranty. On Thursday January 15th 2026 the drive start control malfunction warning light along with a P26AE error code displayed. Upon testing the engine coolant bypass valve B control circuit high failed again. Speaking with Toyota my vehicle VIN is not part of the CSP service campaign they have for 19-23 Corolla models. I spoke with Toyota Corporate and they couldn’t/wouldn’t help. This is a severe safety risk as the valve failed at a moments notice with no warning or symptoms. Additionally it can lead to engine stall and catastrophic damage, risking other drivers if engine loses power. This is an ongoing and recurring issue with RAV4/Corolla/Cross models and Toyota is facing a lawsuit here in California from other drivers with the same problem. I would like for my VIN to be added to the safety recall as Toyota Knowingly replaced the Valve with the same defective part per the technician who fixed my vehicle the first time who warned me this was going to happen again. Thank you for your time and assistance in this matter.

Dear National Highway Traffic Safety Administration, I am submitting this email to formally report a potential vehicle safety defect involving my 2022 Toyota Corolla. Vehicle information: - Make/Model: 2022 Toyota Corolla - In-service date: 08/18/2022 My vehicle sustained significant wiring damage caused by rodents. Toyota has denied warranty and financial assistance, characterizing the issue as an “outside influence.” However, according to what I read online, modern vehicles —including Toyota models—use soy-based or bio-based wiring insulation, which is widely documented to attract rodents. The damage affected critical electrical wiring, creating potential safety hazards including loss of vehicle function and increased fire risk. This is not merely cosmetic damage but impacts essential vehicle systems. The foreseeability of rodent attraction due to wiring materials raises concerns of a design-related safety defect and failure to adequately warn consumers. Toyota has stated there are no recalls or customer support programs addressing this issue, despite recurring reports from vehicle owners nationwide. I respectfully request that NHTSA review this matter as a potential safety defect and consider whether further investigation is warranted. Thank you for your attention to this safety concern. Sincerely,

Coolant bypass value change and they have put 500$ for labour total 656$ for value change

The contact owns a 2022 Toyota Corolla. The contact stated that while driving 15 MPH, while the transmission was shifting into second gear, and attempting to depress the clutch pedal, the clutch pedal depressed to the floorboard. The contact was assisted by a bystander with the failure. A dealer was contacted. The vehicle was taken to a dealer to be diagnosed. The vehicle was diagnosed with a slave cylinder failure. The slave cylinder was replaced, and the vehicle was repaired. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 110,000.

My engine stalled while driving. My low tire pressure light came on and an hour or so later I was turning left at a light. My left turn signal was on. Suddenly my car stalled and the message that stated Put in park, steering power low showed on screen. Put car in park and restarted and it started right up. Dealer said no codes and could not replicate. Only 18,000 miles on car. Huge safety issue!!!!!

2022 Toyota Corolla Hybrid Touchscreen/Infotainment Display randomly shut down while driving without warning and no longer functions. This could not be reset by holding the power button or disconnecting the vehicle battery. The backup camera still works, and the radio can be heard when the power button is pressed, but the display remains on a black screen and none of the controls on the steering wheel or headunit work. At night, the lights on the buttons for the multimedia display turn on and off every 10 seconds which is extremely distracting and has the potential to cause an accident. This defective part serves as a safety issue, as this is where critical maintenance and hybrid battery power related errors displayed. In addition there are many critical controls locked behind the screen related to door locks, hybrid battery usage, and other vehicle controls, as well as personal data that may now be at risk and unable to be able to be deleted. Vehicle was inspected by a Lia Toyota of Rockland Dealership Service department and determined to be a faulty display, requiring a compete unit replacement. The quoted cost is $2500, and despite my car having only 35500 miles, this is not covered under any warranty due to being outside the 36 month time window. The multimedia display in this car is a critical component and is just as vital to the car as the engine/transmission. It is a shame that Toyota reliability is a thing of the past.

The Slave Cylinder failed at 33,186k. So, now the car is needing a new slave cylinder and clutch because the clutch has been contaminated.

The contact owns a 2022 Toyota Corolla. The contact stated that while driving at an undisclosed speed, the clutch in the manual transmission vehicle briefly failed to engage, disabling the ability to shift gear. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 81,000.

Clutch slave cylinder failure at 26,261 miles

Mechanical failure of the headlight assembly system. Sensors for the headlight assembly is sending false failure alerts.

Exterior headlight design is a big safety issue when driving at night. The low beams do not offer enough lighting when going around turns or hills. Even on flat roads it is not enough and very dangerous. The high beams help but are also not providing the visibility needed at night . When raining and using low beams at night it’s like driving in the dark! Please redesign!

On October 1st, 2025, I was in a car accident. I was side-swiped on the highway by a truck, which led me to collide with a metal fence. My airbags did not deploy after the collision. After filing a claim with my insurance company on October 1st, I was informed the same day that my vehicle is a total loss. Prior to the accident, there were no warning lamps or messages.

The radiator had a severe pin hole in several veins causing coolant to leak out and making the car overheat. The overheating seems to happen over a long distance drive jeopardizing my safety and family. To prevent futher damage to the car and my safety. Yes. I have to wait for hours on the side of the highway for hours-to let the car cool down and add recommended coolant for the car. The vehicle was inspected by TOYOTA of San Louis Obispo. 09/29/25. I am not certain if the vehicle was inspected by the manufacturer but the service repair was done @ Toyota dealersip. The temperature or the coolant gauge moved erratically.

Internal short within headlamp assembly causing the fuse to blow. Unrepairable, requires full replacement of part. Confirmed by MyAutoImports licensed Toyota repair center. Passenger side day running light, headlight, and brights are inoperative. Turn signal and front right indication light are still functioning. No warning prior to, but system warning came up after the short first occurred telling me to take into a dealer asap.

Hi, I recently relocated from Vancouver, Canada to Seattle, Washington, and I am in the process of importing my Canadian-purchased 2022 Toyota Corolla into the United States. I have already contacted Toyota Canada, but they informed me that they do not issue compliance letters for vehicles distributed under Canadian regulations. I then contacted Toyota USA, who confirmed that this matter falls under NHTSA’s responsibility and advised me to request the compliance letter directly from you. Therefore, I respectfully request that NHTSA to solve this issue so that I may complete the import process in compliance with U.S. regulations. Please advise me on the next steps to obtain this letter, including any required forms or supporting documentation I should provide. Thank you for your prompt attention to this matter.

I was at a red light and when it turned green, I had the clutch in and was in first gear, but as soon as I barely lifted my foot, the car started moving forward on its own. I almost rolled into the car in front of me. At first, I thought maybe it was just me or the shoes but then I noticed the clutch felt like it was getting stuck while pressed. When I tried changing gears, it made a metal-on-metal scratching noise.When I was coming to a stop, the car wouldn’t slow down properly because the clutch wasn’t responding. I couldn’t press it in, and since there were pedestrians nearby, I had to slow the car down by shifting gears without using the clutch and pedestrians got anxious and mad around me because they had to speed up to the safe side, pulled to the side and checked the pedal, thinking maybe something was in the way, but when I pumped it a few times, it started working again. for a moment. Then at another red light, the clutch pedal went soft and wouldn’t engage again. I couldn’t move the car. Eventually, it turned off, and I managed to get it into first gear and restart it, but the car jumped forward as soon as it started. I kept pressing gas and going, but I couldn’t shift into second gear anymore. Traffic was building up and I barely made it to a safe spot near a crosswalk. It felt unsafe to drive. And had to be tow then I did some bleedings and changed fluids no response. After finally being seing by toyota and researching; all Toyota Corolla from 2020 and up have this problem the so called Clutch Master Cylinder it breaks so premature my car barely has 41k miles on it. Unacceptable and warranty wont cover it

Toyota defectively designed and/or manufactured coolant bypass valves ("the Defect") that prematurely fail. When the Defect manifests, coolant leaks out of the closed-loop coolant system. This adversely impacts the ability of the coolant system to properly regulate the temperature of the engine, and can lead to engine overheating, stalling, increased emissions and catastrophic engine failure. In addition, the leaking coolant can leak into the surrounding engine components, including the electrical system, and damage those components. The leaking coolant can also corrode the sensor on the coolant bypass valve, which causes it to remain stuck in the "open" or "closed" position and thus impedes its ability to properly direct coolant throughout the engine, thereby impeding the ability of the engine to operate within the appropriate parameters. When the Defect manifests, it also causes a message to appear on the dashboard over the speedometer, which states: "Engine Maintenance Required" and "Visit Your Dealer." The message cannot be dismissed or otherwise removed from the dash of the Class Vehicle by the operator of the Class vehicle, and instead must be brought to a dealership or to a mechanic. The message is distracting and obscures a significant portion of the speedometer. blocks other important, safety-related messages that are intended to display in the same area of the dash occupied by the message. Cars system reads “engine maintenance required” due to coolant bypass valve, car is only at 42,000 (6,000 miles past warranty) was told it’s not covered under powertrain warranty and was charged almost $1000 to get it fixed

The contact owns a 2022 Toyota Corolla. The contact stated that while the vehicle was stationary, the emergency button failed to respond. There were no warning lights illuminated.
