Service brakes

61 reports12 crashes
“The brake booster assembly failed, as many of these models had before. A bunch of codes went off as I was driving and the brakes did not function properly. Toyota had an extended warranty for this which they discontinued last year and they would extend no good will towards the $4,000 repair”

Electrical system

24 reports4 crashes1 fire
“The headlight bulbs keep going out. I have replaced the bulbs at least 2-3 times a year for the past few years. I have asked dealers about this and they tell me there is no recall or tsb. This is a hazard to night driving because of decreased illumination, especially in dark roads with not enough lighting. Please recall/fix this issue!!”

Power train

16 reports5 crashes
“My mom was involved in an accident in her 2015 Toyota Prius on April 19, 2022, which she advised lurched forward at a stop and when applying the brakes to stop the vehicle, she said was unresponsive, causing her to clip a vehicle and sending her vehicle into a ditch totaling her car and injuring her passenger and her. I would like to have this investigated and hold Toyota responsible. This could have been much worse and lives could have been lost. She is now without means of transportation, and she is now possibly responsible for damages to property and bodily injury because of this. Through my research I have discovered multiple class action lawsuits brought against Toyota for the same exact models. I asked the police officer to run a scan on the computer, but he advised it was only for serious accidents. There was no indication of the problem or messages.”

“I am having a hybrid propulsion system issue due to a part that was recalled according to this ID number for the NHTSA 17V718000 that was posted NOV 14, 2017 and my car does seem to be affected because it is facing the same issues as other cars reported from that batch. I want to make sure that I can have it serviced properly at my dealership”

“ANYTIME I CHANGE ELEVATIONS THE ENGINE SEEMS TO REV WHEN IT IS IDLING ON CRUISE CONTROL. ON THE DOWNHILL, THE CAR WILL ACCELLERATE TO IGNORE THE SPEED ON CRUISECONTROL TO DANGEROUS HIGH VELOCITY. I REPORTED THIS TO TOYOTA OF NORTH HOLLYWOOD THREE TIMES... IT WAS NEVER ADDRESSED.”
