2019 Toyota Corolla: engine overheating

Filed Aug 17, 2025 · Engine, Fuel system · CA

I have a 2019 Toyota Corolla Hatchback. The problems started on July 21st, 2025. While driving my 2019 Toyota Corolla Hatchback, I noted white exhaust smoke, even after the engine was warm. One week prior, I had filled the coolant reservoir, but when I checked it, the coolant was almost gone again. There were no visible leaks or puddles under the car. I refilled the coolant, but within days the car began shaking severely upon startup and emitted a coolant-burning smell. 5 minutes after, multiple warning lights illuminated on the dashboard simultaneously. I replaced the car battery, and the warnings disappeared. However, while merging onto the freeway, the same warning lights came back, the car lost power, and I could not accelerate above ~25 mph. If this occurred in heavy traffic, it could lead to a serious collision. I exited the freeway and had the car towed. DTCs from the independent mechanic and the Toyota dealer included: P11ED00 P030085 P030027 P030200 (Cylinder 2 misfire) C142571 (Stop light relay actuator stuck) U1117 B2284 B15AD The Toyota dealer identified a “Port Injector #2 malfunction” and recommended replacing all four injectors (~$2,000) but could not confirm this would fix it. They noted a coolant-burning smell but advised addressing the misfire first before further diagnosis. There is an active class action lawsuit alleging that 2019–2023 Toyota Corolla and RAV4 models have defective coolant bypass valves that may cause engine issues, overheating, or coolant loss without visible leaks. This matches the coolant loss, white exhaust smoke, and eventual power loss while driving. I request that the federal safety agency investigate this issue in connection to the reported coolant bypass valve defects affecting 2019–2023 Toyota Corolla models.

While driving my 2019 Toyota Corolla Hatchback XSE, I lost almost all power to my accelerator and a check engine light appeared on my dash. I came to a stop and stalled the vehicle, once it stalled I turned the engine back on and shifted into reverse a felt and heard a loud clunk noise coming from right under my car and its not only shifting into reverse is the loud noise active but its also shifting into drive from reverse. I scanned my vehicle with a aftermarket scan tool and got 2 exact same codes for "Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance/Stuck Off" and then two more codes for "Torque Converter Clutch Pressure Control Solenoid Control Actuator Stuck On". My torque converter in my CTV transmission failed. I was not at a risk of putting other people or myself in danger but if would have if i was moving faster at the time this happened. I have done my research on the recalls that are active on this vehicle and on the Toyota OEM TIS website there is only 1 recall that was taken care of in 2021 for the fuel pump and then there is a Warranty Enhancement Program for the Flow Shut-off Valve Coolant Leak. I did not find anything on that Toyota TIS website about the CVT recall but when i search my year, make and model on the web, I see that there is a recall for about 3,400 vehicles in the USA and nearly 1,000 in Canada that have a active recall for the CTV. I also saw the recall consequence and it matches up with what happened with my Corolla. I have attempted to contact 5 difference Toyota dealerships in my state to have them help me figure out the issue I am having with my vehicle not being listed in the recall but my CTV just failed. No one has reached back out in the past two days and I am continuing to call almost 3 times a day. I would like some clarity on how I should go about handling this issue.

As I was driving my check engine light turned and also another message saying “Drive-Start control malfunction”. A few second after another light came one showing “Engine coolant Temp high. On 11/24/24 I experienced this mechanical failure as I was driving. I was driving behind another car, where my car suddenly lost power and randomly accelerated almost causing me to crash behind the car in front of me. Thankfully I had time to press on the brakes to prevent me from crashing. I also did some research to see if other drivers also experienced this fault and seems that a lot of people with these Toyota Corolla and RAV4 models. I also found that an active lawsuit is ongoing against Toyota regarding this same issue. This definitely should be something that needs to be recalled as it puts our lives at risks to either crash or even catch on fire due to overheating. My vehicle gets serviced regularly.

At around 36,500 miles, my Toyota Corolla began experiencing issues with the coolant bypass valve, leading to engine overheating. This malfunction has significantly impacted my ability to drive safely, as the vehicle displays a notification every five seconds, obstructing my view of the digital speedometer and making it difficult to accurately monitor my speed. The issue was not indicated by a check engine light but a persistent "Engine Maintenance Required" message. This defect poses a serious safety risk, and there's a potential class-action lawsuit in progress regarding this very issue, suggesting Toyota might have known about the defect but failed to disclose it. The faulty component is not available for inspection upon request. As more people began to experience similar circumstances, it could lead to fatalities. Other participants to the forums says the issues start when their covered warranty expires. Within these forums there's a inconstancy of service centers honoring fixes, with no cost, knowing that there is an issue. I took the car to both a third-party mechanic and an authorized dealership, and both confirmed the problem. I was quoted $732.85 for the parts and labor within my area. I also called Toyota Global which I was told "a low mileage car shouldn't be having this issue", however, there are countless of forums saying otherwise. **Toyota Models Affected** 2019 Toyota RAV4 2020 Toyota RAV4 2021 Toyota RAV4 2022 Toyota RAV4 2023 Toyota RAV4 2019 Toyota Corolla 2020 Toyota Corolla 2021 Toyota Corolla 2022 Toyota Corolla 2023 Toyota Corolla [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

* What failed was engine coolant bypass valve. * Safety was at risk as the failure can lead to engine overheating over time. * it has been reproduced by countless others after their vehicle hits 30k to 70k. *there was a message on the dash about “engine issues and to take to dealer”
