NHTSA complaint #11301493, filed 2020-01, 60,000 miles“After purchasing this car, we noticed that the front speakers were not working correctly. It was taken to a repair shop and the mechanic indicated that they were not installed correctly at the factory. The electrical speaker contacts were pointed upwards which effectively damaged them over time from the moisture accumulating within the front doors. Both speakers, passenger and driver sides, indicating the wiring error. Both were replaced by the shop and at their suggestion, I am alerting you to the problem.”

The car had just passed its 20,000 warranty check with no problems. I was on the way to a regularly scheduled oncology appointment. I had to cancel the appointment and drive the car to the dealer. Technicians determined a rodent had chewed through the transmission control harness. This problem is not covered by any Toyota warranty. So far, I've been forced to spend nearly $1,000 on rodent-related repairs. I have stage iv cancer. …”
