2022 TOYOTA COROLLA Engine Problems

Dear National Highway Traffic Safety Administration, I am submitting this email to formally report a potential vehicle safety defect involving my 2022 Toyota Corolla. Vehicle information: - Make/Model: 2022 Toyota Corolla - In-service date: 08/18/2022 My vehicle sustained significant wiring damage caused by rodents. Toyota has denied warranty and financial assistance, characterizing the issue as an “outside influence.” However, according to what I read online, modern vehicles —including Toyota models—use soy-based or bio-based wiring insulation, which is widely documented to attract rodents. The damage affected critical electrical wiring, creating potential safety hazards including loss of vehicle function and increased fire risk. This is not merely cosmetic damage but impacts essential vehicle systems. The foreseeability of rodent attraction due to wiring materials raises concerns of a design-related safety defect and failure to adequately warn consumers. Toyota has stated there are no recalls or customer support programs addressing this issue, despite recurring...

The radiator had a severe pin hole in several veins causing coolant to leak out and making the car overheat. The overheating seems to happen over a long distance drive jeopardizing my safety and family. To prevent futher damage to the car and my safety. Yes. I have to wait for hours on the side of the highway for hours-to let the car cool down and add recommended coolant for the car. The vehicle was inspected by TOYOTA of San Louis Obispo. 09/29/25. I am not certain if the vehicle was inspected by the manufacturer but the service repair was done @ Toyota dealersip. The temperature or the coolant gauge moved erratically.

Car stalled at stoplight. Loud tone sound with ‘power steering low’ indicator with check engine light on. Wheel locked. Needed to put in park and restart car. Very scary and unsafe! Multiple people on Reddit and YouTube have reported this!

There has been several instances where I’m trying to cross a divided Highway and the accelerator doesn’t respond. I’ve had three near death experiences. There’s been other times where it will just shut off and restart without a warning. It’s been in my driveway thankfully. When I pull out in front of someone, it doesn’t respond either. I have had the pedal all the way down to the floor and it wouldn’t go for about 5-6 seconds

The car had shut down on the street while driving twice.
