after shortly pumping gas, I received a alert on my car that I needed to check my fuel cap, after checking fuel cap I proceeded to drive on the highway during this time a multitude of sensors started to go off on my car, and it started to drive weird there were light such as my interlock, being deactivated, parking, brake, deactivated, malfunction of VSC, collision deactivated. 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.

We rented a 2020 Toyota Corolla from Hertz at the McCarran Airport Las Vegas NV and almost past out while driving due to Carbon Monoxide poisonings. My wife was sick 3 out of the 4 days while this auto was being driven in our possession. At first our sickness was thought to be motion sickness or maybe from something we ate. It wasn't until we drove this car out of town when we both my wife and I started getting very sick weak dizzy and vomiting. We tried to drive out to the Hover Dam but stop about 10 miles short. After a brief rest we decided to had back to Las Vegas. Just outside of Las Vegas I could hardly breath and had all the same symptoms previously stated. Luckily I was able to get out of traffic and pulled off the high stopping at the first place I was able to pull into. I believe that If I didn't do so I would have passed out and may have caused an accident. Roadside assistance stated this is a common thing in Toyota's. My concern is how many of these cars are rentals and how many people may have been in accidents and the driver blamed? Please google 2020 Toyota Corolla Carbon monoxide poisoning for morning formation. Feel free to call me at [XXX] for more details.
