“2006 Highlander Hybrid, check hybrid system, check vsc light, brake and ABS light all on permanently and my brakes aren't working. I was fortunate noone got hurt.. It was really dangerous when you press the brake and it doesn't stop. ... From what I read ABS accumulator which cost 3k+ to replace and the hybrid inverter which cost 5k+ to replace. Nhtsa please issue a recall on this issues.”
NHTSA complaint #11073977, filed 2018-02, 149,500 miles“Abs system failed at 137,000 miles , mechanics stated this should never happen,I was driving when ABS brake light came on and continues to stay on, and on 09/17 my ABS and brake light is on,and when I push brake petal down , my car does not stop. Unable to get car to come to a stop. I recently change my brake pads in august and everything was working perfectly untill septamber 20th 2017”
NHTSA complaint #11032272, filed 2017-10, 138,000 miles“While driving through virginia foothills, the entire electrical system on my hybrid stopped working. I had significantly reduced braking ability, no power steering and was in heavy traffic. This could have been a very serious incident if I had to stop for an emergency. I slowly pulled over shut the system down and after a while the warning lights and warning buzzer went off.”
NHTSA complaint #10416587, filed 2011-08, 79,950 miles“I was driving the vehicle and heard a loud popping noise on the way to the dealership for recall work. Once the technician opened the inverter case we found the wiring harness for both the inverter and transmission were completely melted and cooked due to a fire inside the inverter. I am now looking at a $15000 repair bill with Toyota and luckily my family and I were not burned alive or in an accident resulting in fatalities.”
NHTSA complaint #10593095, filed 2014-05, 107,500 miles“I was pregnant and driving with 2 small children when the lights on my dashboard came on about vsc and a loud ringing happened and then I tried to brake at the stop light and they were so difficult to push I barely stopped in time to avoid an accident. Was told it was the ABS system and that Toyota is aware of this but put stipulations on an extended warranty rather than recall so it's too late for most to get fixed and be covered. This is a huge safety issue and expensive fix Toyota needs to stand behind.”
