“The contact owns a 2006 Toyota Highlander Hybrid. The contact stated while driving 65 MPH, the vehicle stalled with the check hybrid system and two other unknown warning lights illuminated. The contact managed to coast the vehicle to the side of the highway; however, the vehicle failed to restart. Due to the failure, the vehicle was towed to an independent mechanic where a diagnostic test was performed. The mechanic discovered that there was a leak in the inverter cooling system. Upon investigation, the contact discovered an unknown recall that was related to the failure. The manufacturer was notified of the failure but informed her that the vehicle was not included in the unknown recall. The vehicle was not repaired. The failure mileage was approximately 280,000.”

“I can see many complaints similar to mine on line since the car was built in 2006. Driving on a 7hr trip when engine light came on and car overheated. We had to pull over on a busy highway and wait for car to cool down and light to go off. It was scary since I had my child in the car and traffic was moving at 60 mph. The next day I had the Toyota dealer charge me $160.00 to tell me coolant and oil were leaking from the head gasket and the bolt corroded and listed out causing a sealing issue. We just had the car in their shop doing thousands of dollars of maintenance and had a full inspection done in preparation for this trip. We also had fluid leaks from the engine twice before at 65819 miles and again at 84458 miles. No mention of this issue was ever brought up by dealer. I have full records and always did maint as suggested. so now the dealer says it will need a used engine at a cost of $9,000+. I am now without a car. This car should have been recalled and repaired, now it is totaled it. Thank goodness we were not injured or hit by another car on the interstate. sorry unable to send a copy of repair estimate done at Daytona Toyota 386-255-7475”
