What owners report most

Verbatim excerpts from NHTSA complaints, by component

Service brakes

72 reports4 crashes
“My brake actuator assembly failed while driving. The brakes stopped working. The cost to repair is over $3,000. This is a fairly common problem in the 2006 toyota highlander hybrid. In fact, Toyota extended the car's warranty to cover this issue, but it expired in 2017. The problem usually occurs once the car has approximately 150k miles which is likely outside the warranty period. This is extremely dangerous.”

Vehicle speed control

43 reports14 crashes1 fire
“THE BRAKE ACTUATOR IS FAILING AND IS MAKING LOUD NOISES. THE CAR DOES NOT BRAKE NORMALLY. I HAVE REPORTED BRAKING PROBLEMS SINCE I BOUGHT THE VEHICLE IN 2007. WHEN IT HITS A BUMP IT ACCELERATES AND I MUST STAND ON THE BRAKES SO I DO NOT HIT SOMEONE. IT LURCHES FORWARD WHEN IT HITS A POTHOLE OR SOME KIND OF OBSTRUCTION IN THE ROAD. WHEN I WORKED DOWN NEAR THE BUS STATION I WOULD HIT THE AREAS IN THE ROAD WHERE THE BUSES CREATED BUMPS IN THE ROADWAY AND IT WOULD LURCH FORWARD. I REPORTED THIS NUMEROUS TIMES AT NORTH BAKERSFIELD TOYOTA. I RECENTLY WENT IN TO REPORT THE NOISE I WAS HEARING AND THEY FINALLY FIGURED OUT THAT THE BRAKE ACTUATOR IS FAILING. I WAS TOLD THAT IT WAS NOT A HAZARD BUT THEY COULD NOT TELL ME WHEN IT WILL TOTALLY FAIL. I BELIEVE IT IS A SAFETY HAZARD AND THERE HAS BEEN A PROBLEM FROM DAY ONE”

Electrical system

26 reports
“While normally driving on the highway and without no warning the vehicle the power steering stops working , it just dies with no power and dash lights warning start to flash and Check Hybrid System turns on. I am not a mechanic nor a technician . The mechanic disconnected the ground cable after waiting about 5 minutes and it resets the system. He told me that it has something that may be caused by some electrical problem . He thinks that it has to do with a recall about some soldering electrical part in the inverter control. This has happened in 3 more occasion and I've been lucky and i have time to let it go to side of the road and i disconnect the ground wire for 5 minutes and connect it back and it resets and then starts to work normal. Since the vehicle stalls completely i fear that this could cause an accident or lost of life due to other vehicles coming behind at high speeds . Please i need help!”
