“Was commuting back to work from lunch break when out of nowhere I lost control of steering and braking of my vehicle crashing into a stone wall before I could pull my emergency break after the vehicle could not slow down on a city street in motion”

NHTSA complaint #11162878, filed 2018-12, 45,000 miles

“After having the vehicle for about 6 months, first, the passenger door began to intermittently respond to locking/unlocking commands. Neither the key fob nor the switch in the vehicle would work, and eventually the door lock had to be manually operated. A few weeks later, the driver side door began having the same issues. The vehicle has not been involved in any crashes according to online databases. No damage to either door has occurred that could compromise any electrical mechanism with exposure to the elements. …”

“The contact owns a 2014 Scion TC. While driving various speeds, the maintenance required and engine warning indicators illuminated without warning. The vehicle was taken to toyota momentum in fairfield, california where it was determined that rodents had destroyed the wiring harness in the vehicle due to the soy based construction of the wires. The wiring harness was replaced. The manufacturer was made aware of the issue and stated that there was no recall on the vehicle. The failure mileage was approximately 51,000. The VIN was not available.”
