2019 Toyota Corolla: sudden loss of power

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.

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.

I have been losing power on my 2019 Toyota corolla hatchback since I purchased this new vehicle I have taken it to the dealer many times and they have been unable to fix it, lately in the past 6 months I have been getting a sign that only stays on for a few seconds when I lose power and I have been unable to read it so I purchased a dash camera and I mounted it in front of the vehicle screen and today I was able to capture and it said Accelerator and Brake Pedals Pressed Simultaneously. This is incorrect I only drive with one foot; I know my vehicle is now out of warranty but I have had this same problem since I purchased the vehicle.

On march 2, 2019 I purchased a brand new 2019 toyota hatchback from toyota of richardson. After only owning the car for 3 weeks I received a notice from my vehicle's alert system that there was a safety recall on it. I was never told this by the auto dealer or by toyota. The recall was due to an error with the manufacturing of the vehicle. In researching this, I found that in december of 2018 this recall was publicized on the world wide web and with the federal safety agency. The torque converters is defective and could cause a crash when the car has rapid acceleration. The vehicle could suddenly lose power while driving. My daughter, who is the co-owner of this vehicle, is the primary driver. She has 4 children, in which one is handicapped. She and her children has been at risk when driving and/or riding in this vehicle since the purchase date. So, for 3 weeks my family was at risk of having an auto accident due to a manufacturer's default in which a recall was issued 3 month prior to the purchase of this vehicle! Yet the dealer did not take the time to fix this problem prior to our purchase. This is ridiculous!!

I received a letter from toyota stating that there is a problem with the CVT and that it could fail. Under certain conditions it could cause the vehicle to lose power, especially at higher speeds. I have contacted them and there is no resolution as yet. I feel extremely unsafe driving this vehicle, I was told it would be addressed when I took the car in for the 5000 mile service but I was given erroneous information. I don't think I should have to wait for something to happen in order to resolve this issue. If a remedy is not available then I should be afforded a loner until such time when toyota comes up with a fix.
