Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Squirrels keep eating my electrical wiring and the wiring harness. They access the engine bay through the openings in the wheel wells after jumping on top of the tires. The results have disabled my ABS, 4wd, limited slip, etc. I've tried rodent repellent, fox urine, and parking in the garage. Nothing helps. Toyota needs to stop using soy based wiring, and they need to close the holes in the wheel wells.”
NHTSA complaint #10859964, filed 2016-04, 63,000 miles“I was involved in a crash. I checked the rear view mirror preparing to brake in traffic. Before my eyes returned to the front I was crashing into the back of the vehicle in front of me pushing him into the car in front of him according to the driver in front of me. I have no idea how I got so close so fast I believe when I went to break the gas peddle was too close to the brake peddle also above the brake peddle. At the time of the crash I was in shock.and I couldn't explain what happened. …”
