2010 TOYOTA PRIUS Complaints

Driving when I had to stop because of traffic light. Almost ran into a car because my brakes did not function correctly. ABS light and brake lights in dashboard came on. Pulled over. Called Tow truck. Had it towed to dealer. Brake Booster and master cylinder were replaced.

Own a 2010 prius w 110k miles on it and now hearing brake booster buzzing every minute when car is on when im sure its not suppose to be going off that frequently. And of course I missed the recall date.

I was driving my 2010 Toyota Prius and my car started beeping when I was driving when I tried to slow down the car was not able to stop the breaking system ABS started displaying and my car started to beep and it won’t stop beeping. I did take my car to the dealer for a recalled inspection after my car broke down and I was no longer able to drive for my own safety. After I took the car to Downey Toyota for hybrid recall they didn’t tell me anything but on the document they gave me it did state that the ABS was a problem. Now my car is still not able to be used because of my own safety concerns since the vehicle won’t break when I put the brake pedal and a none stop beeping sound that won’t stop at all.

The brake booster assembly and pump failed in my Prius. This causes the brakes to barely function. It disables both ABS and traction control. I nearly ended up running a red light and getting into a major collision with my three children in the car. The ABS, traction control, and BRAKE lights are all illuminated. Toyota advised they are aware this is a common failure but refuse to fix it. A dealership inspected it to confirm the flaw. Toyota will not fix it so I am forced to drive this vehicle with barely functioning brakes with my 3 children in the car still as I have no choice.

There is a long-standing problem with the instrument panel being very difficult to see when operating the vehicle on a very sunny day. It is very dim even when the "instrument panel light control" is adjusted, especially when wearing sunglasses. No response by dealer.

Brake booster actuator internal leak. Toyota refuses to cover the repair for the known defective and previously recalled part. See recall "D0H" and "customer support" campaign "ZJB" from Toyota. These are critical braking parts that control ABS, traction control, stability control, front/rear brake bias, regenerative braking and brake pedal feel and pressure. Loss of braking and all previously mentioned safety features occurs when the car sets the error codes, disabling and crippling the braking system. Longer stopping distances and much less responsive brake pedal is immediate. This part costs $700 from the dealer and they want over 2000 to fix the car due to the known defective, recalled part. This affects most Toyota hybrids of this era. The Prius is especially important to get recalled IMMEDIATELY, due to this being a common taxi and rideshare car, carrying multiple lives and heavier loads, in more severe operating conditions. Please look into this!! Toyota corporate has been called and they refuse to help or acknowledge the problem.

Brake, ABS and traction control warning lights went on when I was driving. I was able to brake but it was not functioning at 100%. The local mechanic was able to scan the code to get the C1391: Abnormal Leak of ACC PRESS error. The warning lights remain when I drive or parked. I no longer feel safe driving my vehicle. I plan to take my car to the Toyota dealer for further diagnosis and repair. I was informed that this is a very costly repair.

The contact owns a 2010 Toyota Prius. The contact stated while driving approximately 70 MPH, the vehicle suddenly stalled. The contact stated that the power steering and power brakes failed. The contact stated that the "check hybrid system" and "check battery" warning lights were illuminated. The contact steered off the roadway safely; however, he was unable to restart the vehicle. The contact had the vehicle towed to an independent mechanic, who diagnosed the vehicle and determined that the inverter needed to be replaced. The vehicle had not been repaired. The contact researched online and related the failure to NHTSA Campaign Number: 18V684000 (Hybrid Propulsion System). The manufacturer had not been informed of the failure. The failure mileage was approximately 387,000.

Brakes became soft the stopping distance grew.All my dash warning signs lit up. Why was my car to repaired in warranty or recalled when the problem was a manufacturer error? Toyota can't pick and chose which cars they will fix when they all have the same problem. I am attaching a 'Customer Support Program' sample and my car falls under the Primary Coverage section. My car was diagnosed at a dealership on 5/14/2021. But not fixed under warranty or recall. Toyota has recall on brakes for many of the newer cars too. Same issue.

My brakes are failing. The brake booster leaks. The stopping distance is greater. All the warning lights are on on the dash. Error code C1391 on the unit. Two dealers would not repair it under warranty or recall. They gave me a price of $2600-$2800.The situation still exists. The car has had the engine replaced out of warranty but by the dealer but the brakes were not replaced as a preventive measure.
