My vehicle experienced a loss of oil pressure and massive oil loss while being driven due to the failure of the oil cooler line while driving on PA 291 in philadelphia. It had to be towed. This is apparently a common problem for the Highlander and the Lexus rx350.

4 Engine And Engine Cooling problem

Failure Date: 12/16/2018

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. Prior to the fire, there were no issues with the vehicle. The Highlander was stationary, with the ignition off and parked in the garage. 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. All three sources of ignition remain energized with the ignition off. 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. The ends of the receivers had alloying on the receivers, but no failures were noted on fuse panel or battery. Extreme thermal damage was observed on the connector end of the solenoid where most of the facing had melted or was consumed. Lines of demarcation from extreme heat was observed on the remaining section of the solenoid facing. The cable connecting the battery to the solenoid was not connected to the solenoid due to the extreme damaged to the solenoid. The terminal connector on the cable sustained arcing and/or melting of the metal terminal. The conclusions were that the fire was caused by a failed solenoid attached to the starter on the 2010 Toyota Highlander. Lab analysis of the starter/solenoid revealed failure at the connection end of the solenoid with beading and arcing on contacts inside the solenoid.

5 Engine And Engine Cooling problem

Failure Date: 02/20/2018

Stopped at a traffic light with the brake applied, the engine began to rev uncontrolled and began to move forward towards the car ahead of us, even with the brake fully applied. To stop the problem, the transmission was shifted to park and ignition turned off.

6 Engine And Engine Cooling problem

Failure Date: 09/01/2014

Twice in September 2014, as I was approaching a stop light, I pressed the brakes and slowed to nearly a stop. 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. The engine was running so high that it was difficult to keep it from moving. 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 immediately returned to normal idle. This same sequence happened both times. This has happened twice this month, but these are the first occurrences since I purchased the vehicle new. 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. They indicated that the vehicle data recorder would not record such an event. 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). I have already decided that should it happen again, I will trade the vehicle. I don't like having to keep my hand on the gearshift, ready to shift into neutral. I saw a report in usatoday that sudden acceleration in Toyotas is being investigated again. I wanted to add my experience to the mix.

7 Engine And Engine Cooling problem

Failure Date: 02/22/2014

While driving on the interstate at 70 mph, a deer hit my car. Airbags did not deploy, damaged front end, minor damage to the bumper, major damage to engine compartment and windshield was cracked why did the airbag not deploy our major oncern concern that will the airbag work after repairs??.
