Then suddenly while driving at an accelerated speed, and trying to slow down, my engine turned itself off, and I was not able to re-crank my car. There is an active recall with Toyota for the fuel pump, which I was told by Toyota was the issue, but due to my VIN not being associated they would not repair as a recall

My car is at around 42,000 miles and has had an engine maintenance light on. I take it in and it’s a defective coolant bypass valve issue. The dealership tried to charge me 800 dollars to replace it. It’s an apparent fault on their part since it has been an apparent problem with other toyota corollas with a lawsuit already filed.

I purchased my vehicle new in 2020. I am currently at 74,000 miles and noticed my engine maintenance required light come on although I received an oil change service two days prior. It’s a different message from the routine maintenance. I got it checked out at Toyota today and the “engine coolant bypass valve” needed to be replaced. When I looked into it I noticed the 2020 Camry and 2020 rav 4 were recalled for the issue and repaired for free. However my model Toyota Corolla was not recalled and I had to pay $700.82 to get it replaced at Toyota today.

The fuel gauge suddenly malfunctioned giving a false reading of the amount of fuel remaining in the tank. A technician said that the problem seems to be with the sending unit in the tank. I use top tier gas and the car has only about 29,800 miles. The fuel gauge continues to malfunction and could be a generic design flaw. Safety could be put at risk if the vehicle ran out of fuel while driving in traffic. There were no warning lights, messages or other symptoms of the problem prior to the failure.

While operating our 2020 Toyota Corolla hybrid at a slow speed in a parking lot, we began to apply the brakes as we pulled into a parking stall. As the brakes were applied , the vehicle suddenly lunged forward with abrupt force. Both tires left acceleration marks on the painted concrete curb and the vehicle struck a large concrete pillar with such force that the pillar was partially dislodged from the ground. The vehicle was brought to a Toyota dealership and the sales management was notified of the incident. We also filed complaint with the Toyota Corporation. We were contacted by a Toyota Corporation representative and were told that they would conduct the vehicle inspection. Several weeks later we received a letter from the Toyota Corporation legal department which informed us of their findings. The letter conveyed that no defect was discovered and the incident had not been captured in the vehicle's computer. We informed the Toyota dealership of the results. The only assistance offered was their willingness to sell the vehicle at auction, which we adamantly declined. At this time we are making arrangements to have the vehicle towed to a recycling lot for destruction.

I have only had the car for a year and a half, and I have already had to replace the battery which was less than 2 years old, all 4 tires (2 at 40000 miles and 2 at 48000), and now the engine wiring harness somehow got severed and has to be replaced which is almost $6k repair!
