I own a 2010 Toyota Prius hybrid 4 door sedan. I am the second owner of the vehicle. I purchased it in 2018 from a used car dealer. The vehicle ran well up until 2022 where a “check hybrid warning would appear on the dashboard along with a yellow triangle and service engine light would come on and the vehicle accelerator would not respond and the car would have to glide to the side of the parkway. This problem would happen when the car speed is between 60-70mph. It is very dangerous to lose power on the highway because many times there is no where to pull over. In 2024 I changed the water pump because the fault code on the cars built in diagnostic code read error “P216B” which is the cars electrical water pump signal. I researched it on google and a lot of 2010 Prius owners are complaining of the same thing. Also the changed water pump from April 2024 died again in January 2025. It is very scary that the cars accelerator pedal goes unresponsive and all the fault lights come on. My vehicle has 155,000 miles runs great and my family loves the 40mpg it gets. However, this stalling problem is being ignored by Toyota and could lead to a fatal car accident if not recalled by the manufacturer. To conclude, I would like for your office to possibly conduct an investigation with the 2010 toyota Prius hybrid for this ongoing problem that the company is ignoring. This is a serious issue and can possibly lead to a fatal accident. THANK YOU FOR HEARING MY COMPLAINT AGAINST TOYOTA.

My car accelerated significantly on its own while I was pulling into a parking stall in a private parking lot. It caused my vehicle to jump a curb and accelerate up a dirt divider and push over a bush that was planted in the dirt divider. Depressing my brakes did not Decelerate the car, so I pressed the Park button to eventually stop the vehicle. I’m not sure what speed it was traveling when it accelerated, but I could smell burning rubber at the end of the incident. I’m not sure when the smell first occurred.

I was driving in my neighboorhood and as I went up the wall bridge my acceleration stalled and my ABS light, Check engine light, and check hybrid system light came on simultaneously and started beeping. At the same time, I lost my braking ability completely. I had to swerve off to the grass in the hopes of not hitting turning traffic at the stop sign. Luckily, it stopped before doing any major damage to anything. Thankfully, I was close to home and was able to put it in my driveway safely. The check engine light then cut itself off, but my brakes remained completely nonfunctional. If this had happened on the highway or a busy road I'm sure it would’ve been much worse.

I inherited a 2010 toyota prius 3rd generation when my mother passed a few years ago. I've since had several unnecessary and costly problems with the car as well as dealership's outlook, treatment, and indifference to the danger that their customers face--as many already have. The following are situations that I'm experiencing now. First, I was recently leaving the pharmacy when all of my warning lights (ABS, brake, traction ) suddenly came on and my brakes failed as I was heading home. I'm a single mother of a special needs child and I had to get home to her. I was approximately 1 mile from my home and I was nearly in 3 accidents that could've been catastrophic. Thankfully the road was dry, clear, and with little traffic. We have been homebound for weeks, without transportation for doctors, food, etc. Our vehicle is our only means of transportation, and we must get to doctor appointments, etc. Second, the car has inexplicably stalled twice. Third, I'm constantly having to replace lights, and have been pulled over by the police for lights not working. Finally, an airbag has been recalled and once I can afford it I'll get that fixed as well. I spoke with my local toyota dealerships, and after explaining the problems, I was informed (several times as I was repeatedly transferred) that I had to pay an inspection fee that also changed with each person. Finally, I was told I had to leave my car there for days and that I was going to pay thousands of dollars to fix the car. I'm unable to pay that much money--and the amount kept changing as well. I have researched these problems and now understand the methodology and intimidation used on poor people such as myself. Toyota should be ashamed. Fix these problems that will endanger and possibly kill your customers for nothing more than their own incompetence and greed.
