Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving in a parking lot, the brakes were pressed to slow down the car to turn into a parking lane. However, instead of braking the car accelerated. The brakes were pressed again, and the car continued to accelerate. The car finally stopped, approximately midway down the parking lane. As a result, my mother and I were involved in a minor car accident.”
NHTSA complaint #10872601, filed 2016-06, 12,700 miles“I received a long technical letter from Toyota with my VIN number warning me of a possible failure of the intelligent power module in my 2015 Prius. It says this is not a recall, but rather an advisement of a voluntary customer program that has been initiated for my vehicle. It says that if I have the included symptoms, to bring it in for evaluation, and a repair will be attempted, but if the problem is not the ipm, I will have to pay for the investigation. This sounds most unfair. I do not have the skills to make the necessary determination. …”
NHTSA complaint #11400147, filed 2021-03, 25,000 miles“At 41,000 the vehicle per a goodyear dealer advised that my front brakes were metal on metal. The caliber was also frozen and the brake line was leaking. The car was at the dealership on 3/7/19 with no mention of a need for repairs to the front brakes. Is there a general problem with bad brakes on Toyota vehicles?”
NHTSA complaint #11190229, filed 2019-03, 41,000 miles“My small battery died and it is located on passenger side, inside, underneath tail light. There us no key entry. One must crawl to back if car and dismantle many pieces to access release. I had heavy 5 gallon jugs of water in back. There is no trunk release and no key entry. The only way to jump car is at fuse box under hood. Car needs a button inside, ideally up front.”
NHTSA complaint #11637716, filed 2025-01“The brake booster pump and ABS actuator is beginning to fail recently. I took it to the Toyota dealership to use Customer Support Program ZJB to replace the parts, but they said my vehicle was not covered. They then quoted me $3000 to fix the issue. The brake booster pump and ABS actuator contribute to safety while driving, so why is this not recalled? We need an official recall to happen and not a simple Customer Support Program.”
