2017 Toyota Prius V Complaints

On 10/16/23 I was turning slowly into a parking spot and my car suddenly accelerated without my pressing the accelerator. I slammed on the break and the car stopped. It was frightening because I could have hit someone or something but luckily the car stopped before that happened. I believe that this was a malfunction of the accelerator. This has not been checked or reported to anyone yet but I will be calling Toyota to have it checked. There have been no warning messages.

The contact owns a 2017 Toyota Prius. The contact stated while driving 10 MPH and pulling out of a parking lot, the vehicle lost motive power and made abnormal sounds. Several unknown warning lights were illuminated. The vehicle failed to restart, and was towed to the dealer, where it was diagnosed that the head gasket was blown, causing damage to the engine. The dealer informed the contact that the engine needed to be replaced. The vehicle was not repaired. The vehicle was taken to an independent mechanic, where the same assessment was made. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist because the vehicle was out of warranty. The failure mileage was approximately 80,000.

While filling my Prius with gas, as soon as I started pumping, it spewed gas all over my arms and shirt, as the gas would not go down the pipe into the gas tank. My mechanic explained that gasline exhaust valve was stuck causing the gas to spirt back out the intake opening. This part had to be replaced. Firestone replaced it for a total of $337.08, however, the dealer would have charged more. It was not covered as a defect issue. The experienced mechanic said that he had seen this problem on several Toyotas. This is hazardous and Toyota should repair those that exhibit this problem; also they should change their design so that the exhaust valve does not fail causing gasoline to spill on the person pumping gas and all down the side of the car onto the cement pavement.

When filling gas, a near-empty Prius overflowed almost immediately, splashing fuel over the car, the ground, tires, and my feet! Gas is flammable and not good to get on one's skin. Firestone experienced/certified repairman said that he's repaired many Toyotas with the same problem. No advanced warning was presented. Last time I filled it before this incident it worked fine. Technician said that the air-exhaust that permits air to escape while gas is being delivered to the tank had failed to work properly, causing the fuel to spew back up the gas line and on to the car/ground. He had to order a part from Toyota and replace it. This cost me $337 for part and labor. I believe this is a malfunction that Toyota should cover. This part should not fail as it could start a fire and contaminate the car, ground and put petroleum on people.
