SEATS — Filed 07/27/2026

I was rear-ended by a truck in my prius and my seat laid back on impact. I'm unaware if that was an intended thing or not but it potentially could have injured my neck. My car is currently in a storage lot awaiting the adjustor's inspection so it is available for inspection if needed. No warning lights were available and it hasn't been recreated by the dealer

SERVICE BRAKES — Filed 12/11/2024

On the morning of December 11th, 2024, the brake system warning light (ABS, yellow) illuminated on the dashboard along with the red BRAKE indicator and the yellow Vehicle Stability Control (VSC) system light. I consulted a mechanic who performed a computer diagnostic and informed me that the ABS module booster had failed. He said that will order the part to change it but meanwhile he advised me to drive more cautiously and maintain a greater distance from the vehicle ahead, allowing extra space for my car to stop due to the increased braking distance caused by the failed ABS module booster. Later that day, at approximately 5:30 PM, I was driving home in heavy traffic, with speeds not exceeding 40 miles per hour. The vehicle in front of me began to decelerate abruptly. When I applied firm pressure to the brake pedal to slow down my car, it lost all control. The vehicle began to skid, with the amplitude of the skid increasing progressively. It struck the highway guardrail on the left, changed trajectory, crossed all four lanes to the right uncontrollably, and ultimately collided with the highway guardrail on the right side.

EXTERIOR LIGHTING — Filed 05/01/2024

My vehicle has an ongoing issue with the headlights not being bright enough to drive at night with. I have replaced the headlights more than 5 times now over the course of a year, each time with different brands including Toyota OEM headlights. Each time, they are still not sufficiently bright enough to see with at night. This has led to 3 collisions with curbs and objects which caused damage to my vehicle, because I could not see the objects while having to drive at night. I have brought the issue up to Toyota and they said they would not do anything about it. I brought it in for service to Toyota and they tried to charge me $200 to even look at it, money which I do not have. I am forced to continue driving at night for work and fear I will get into a more serious crash or hit a pedestrian as the headlights aren't bright enough to see safely at night. The photo I have included shows a gash in the tire and dent in the rim where it hit the curb. The issue seems to be the headlight wiring or connectors. When I replace the headlight bulbs, they are a bit brighter initially. Thus initial brightness only lasts about a week, and it's still not sufficiently bright to drive safely. They then dim even further to the point where it's like driving without headlights at all. Again this has led to 3 collisions at this point since I'm required to drive at night and don't have the money to fix it. Toyota refused a good faith repair and did not acknowledge there was an issue, however if you do a web search for "Prius headlights too dim" it seems to be a major issue with many other Prius owners. It should be noted that even the high beam headlights are not bright enough to sufficiently see with at night.

The contact owns a 2015 Toyota Prius. The contact stated that as he approached a stop light at 25 MPH, the brake pedal was depressed and traveled to the floorboard as he attempted to stop the vehicle. The brakes failed to operate without warning as he hit the vehicle in front of him. The air bags did not deploy upon impact. A police report was filed and both the contact and the other driver were able to drive away from the scene. No injuries were reported. Prior to this failure, the contact stated that the same failure occurred months prior while traveling at 20 MPH in the rain. The contact stated that the brakes failed to operate without warning as he depressed the brake pedal to the floorboard; he hit an unknown object on the road due to the failure. The contact initially thought that the failure was related to slippery roadways; however, after the most recent failure, he related the prior incident with his most recent failure. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle had yet to be serviced or diagnosed. The failure mileage was approximately 80,000.

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.

During routine low speed suburban driving, a fire started under the hood in the right front of the car. The smoke was first noticed by a pedestrian so I pulled over, got out of the car, and called 911. I had no prior warning of any sort. The fire completely destroyed the car. This is being investigated by Toyota. I have photos and would be happy to provide more details.

POWER TRAIN — Filed 01/26/2020

THE PRIUS WAS STATIONARY, PARKED IN THE DRIVEWAY OF OUR HOUSE. MY TEENAGE DAUGHTER WAS IN THE CAR WASHING THE WINDSHIELD AND WINDOWS ON THE INSIDE AND ACCIDENTALLY BUMPED THE GEARBOX (SHIFTER). THE CAR WENT OUT OF PARK AND INTO NEUTRAL AND ROLLED BACKWARD. THE ENGINE WAS NOT ON. THE CAR QUICKLY ROLLED 20 FEET INTO A TREE AND CAUSED 6200$ DAMAGES TO THE REAR OF THE CAR. LUCKILY NO ONE WAS BEHIND THE CAR. I BELIEVE THAT THE PRIUS CAN BE ACCIDENTALLY PLACED IN NEUTRAL IF ELECTRICAL IS ON IN THE CAR (IE RADIO) AND SOMEONE HAS THEIR FOOT ON THE BRAKE AND HITS THE GEARBOX BY ACCIDENT. THERE IS NO SAFETY ON THE SHIFTER TO PREVENT UNINTENTIONAL SHIFTING. MANY OTHER CARS REQUIRE A MANUAL BUTTON ON THE SHIFTER TO BE DEPRESSED PRIOR TO SHIFTING. THIS IS NOT THE CASE ON THE PRIUS. WITHOUT THAT SAFETY FEATURE, ACCIDENTS LIKE THIS ONE CAN HAPPEN AND POTENTIALLY KILL SOMEONE. THE CAR CAN BE MADE TO BE IN NEUTRAL BY ACCIDENT RATHER EASILY.

I WAS SITTING IN THE PASSENGER SEAT OF THE CAR WHILE IT WAS PARALLEL PARKED. I PRESSED THE PUSH TO START BUTTON TO TURN ON THE BATTERY SO I COULD CHARGE MY PHONE. THERE WAS NO ONE IN THE DRIVER SEAT. THE CAR TURNED COMPLETELY ON WHEN I REACHED OVER TO PRESS THE BUTTON. NOT ONLY DID THE ENGINE START, BUT WITHOUT ANYONE PRESSING ON THE BREAKS THE CAR RELEASED ITSELF FROM BEING PARKED. THE CAR STARTED ROLLING BACKWARDS INTO THE CAR PARKED BEHIND ME. I HAVE NO EXPLANATION ABOUT HOW THIS HAPPENED. I HAVE BEEN READING INTO IT AND APPARENTLY IT'S A DEFECT OF THE 2015 AND OLDER MODELS. WHEN THE CAR STARTED ROLLING BACK I ALSO STARTED PRESSING BOTH THE PARK AND PUSH TO START BUTTONS TO TURN IT OFF AGAIN. I'VE NEVER FELT SO UNSAFE IN A VEHICLE AND GOES TO CONFIRM THAT PARK AND PUSH TO START SHOULD NOT BE BUTTONS!!! IT MAKES THE VEHICLE MUCH MORE DANGEROUS NOT BEING ABLE TO OVERRIDE THOSE COMMANDS WHEN IT CHOOSES TO GO ON ITS OWN.

SERVICE BRAKES — Filed 10/16/2015

I HAVE NOTICED THAT THE BRAKES SOMETIMES DO NOT APPEAR TO WORK PROPERLY, AND ONCE I WAS INVOLVED IN AN ACCIDENT DUE TO THE POOR BRAKING PERFORMANCE. ONCE I QUICKLY TRANSITIONED FROM THROTTLE TO FULL BRAKING AND THE CAR DIDN'T SEEM LIKE IT WAS APPLYING FULL BRAKING. IT DIDN'T SEEM TO DECELERATE LIKE IT SHOULD HAVE. I REAR ENDED A VEHICLE BECAUSE OF THE BRAKING PERFORMANCE. ANOTHER TIME I HAD TO SLAM ON THE BRAKES COMING OFF AN INTERSTATE AND THE BRAKES ALSO DIDN'T SEEM POWERFUL ENOUGH. IT'S AS IF THE BRAKES DON'T FULLY "CATCH" UNTIL THE LAST MINUTE. BOTH TIMES WEATHER CONDITIONS WERE DRY.
