I wanted to add my experience to the mix.Ĭ ® is an online automotive complaint resource that uses graphs to show automotive defect patterns, based on complaint data submitted by visitors to the site. I saw a report in usatoday that sudden acceleration in Toyota is being investigated again. I don't like having to keep my hand on the gearshift, ready to shift into neutral. I have already decided that should it happen again, I will trade the vehicle. They said they would add a note about this to the record they have on this vehicle (they have done all the service since I purchased it from them). They indicated that the vehicle data recorder would not record such an event. I called the Toyota dealer, and the service person said that if the vehicle isn't demonstrating that behavior when I bring it in, they would not be able to find what caused it. This has happened twice this month, but these are the first occurrences since I purchased the vehicle new. The engine immediately returned to normal idle. I shifted into neutral, came to a complete stop, and while the transmission was in neutral, took my foot off the brake pedal. The engine was running so high that it was difficult to keep it from moving. The engine suddenly accelerated very high, and if I had not already had a foot on the brakes, I would have gone into an intersection. Twice in September 2014, as I was approaching a stop light, I pressed the brakes and slowed to nearly a stop. Lab analysis of the starter/solenoid revealed failure at the connection end of the solenoid with beading and arcing on contacts inside the solenoid. The conclusions were that the fire was caused by a failed solenoid attached to the starter on the 2010 Toyota Highlander. The terminal connector on the cable sustained arcing and/or melting of the metal terminal.

The cable connecting the battery to the solenoid was not connected to the solenoid due to the extreme damaged to the solenoid. Lines of demarcation from extreme heat was observed on the remaining section of the solenoid facing. Extreme thermal damage was observed on the connector end of the solenoid where most of the facing had melted or was consumed. The ends of the receivers had alloying on the receivers, but no failures were noted on fuse panel or battery. The upper portion of the plastic housing on the fuse panel and battery had melted exposing the receivers for the fuses and plates inside the battery. All three sources of ignition remain energized with the ignition off. A subsequent investigation including inspecting burn patterns and thermal damage indicated the fire originated at the front of the Toyota Highlander on the driver's side where the fuse panel, battery and starter/solenoid were located. The Highlander was stationary, with the ignition off and parked in the garage. Prior to the fire, there were no issues with the vehicle.

2010 Toyota Highlander caught on fire while parked in garage of residence, destroying the Highlander and the car parked adjacent to it, along with most of the house.
