My vehicle was not part of the fuel pump recall like the other 3.3M vehicles from Toyota. However, my vehicle exhibited the exact same symptoms as those cars and stranded me on the side of the road twice. This included pushing on the accelerator and getting no response from the car followed by numerous system warning lights including hybrid system malfunction, front collision system failure, and check engine light. Initially, the dealership could not find anything wrong when I first brought it to them. The second time it happened, I was able to bring the car in with the check engine light still on so they were able to diagnose it and are currently replacing the fuel pump. My car (and many others) should have been included in this recall, this is a huge safety issue as this had me stranded on the side of very busy highways twice plus not being able to accelerate in traffic.

I was involved in an accident that I believe was caused by sudden unintended acceleration (sua). In a very busy commercial parking lot, I was pulling into a parking space proceeding at a very slow speed, when there was a sudden surge in acceleration accompanied by a grinding/acceleration sound. I hit the brake to no effect, and the vehicle jumped the curb and hit a building shop and entered the shop. The air bags did not deploy, and I was shaken up but not injured. Thankfully, there was no one at the front desk area of the business. The car was not drivable and was towed to a body shop.
