2010 TOYOTA PRIUS Complaints

The rear axle beam broke off near the passenger side rear wheel. The wheel flops around and the vehicle is totally unsafe to drive.

In 2015 I purchased my Toyota Prius in VA. I now live in Indiana and had my car checked for a possible sensor issue because the traction, brake & abs light were coming on and off. The diagnostic showed a brake accumulator leak malfunction. I contacted Toyota dealership once I was told there was a recall. The dealership said that it was showing it was replaced in 2013 from the previous owner in VA. It was listed then as a recall. I contacted Toyota Corporate and they said that it went from a recall to customer support with a maximum of 150,000 miles. I did not have any more problems until just recent. My argument is once a recall it should still be repaired. The part appears to be the problem. It is a safety issue and I need Toyota to fix the problem. Thank you!

The car suddenly threw a C1391 code yesterday with no previous warning. The traction, parking brake, brake system, and ABS lights are all lit on the dashboard. As this vehicle is my daily commuting vehicle, I must have the costly repairs performed, which are estimated at roughly $2,400. I will ask to retain the parts for inspection. The brakes are softer, and the breaking distance required has increased by approximately fifteen feet.

The ABS Pump( Accumulator and booster) are regularly failing on all Toyota Prius( 2010-2015). When the ABS pump starts to fail, the warning lights for Traction control, Brake and ABS come on. These lights come on at all speeds and its very hard to bring the vehicle to a complete stop when this happens. The brakes completely stop working and the brakes become rock solid. The brakes become so hard that they can’t be possibly be depressed to stop in time. I nearly missed getting killed from this as I am out of country and Toyota is refusing to fix it since its not a recall and I am in Canada. Toyota is asking $3500 in parts and $1500 in labor to repair. I can not afford it and this issue is on all Prius from 2010-2015. This is a major safety hazard and can cause serious injury and damage. Toyota is refusing to repair it since they believe the cars are out of warranty. However Toyota has been notified about this safety hazard arising on all Prius(2010-2015) but decline to respond or take action. I urge NHTSA to take action and get this resolved as the ABS brakes failing on the Prius can be really dangerous and can cause life threatening accidents.

ABS Lights turned on and need replacement. This is my 3rd Prius that have the Issue.

The contact owns a 2010 Toyota Prius. The contact stated while at a complete stop and attempting to depress the accelerator pedal, there was an abnormal vibration coming from the brake pump.

Passenger side low beam headlamp has continued to need to be replaced. I was not made aware of a "customer service protection program" on this and when I contacted Toyota they said it was too late for the repair, electrical harness, to be covered by their extended warranty. I never received information regarding the extended warranty. They stated they sent it to the correct address. But just because you mail something doesn't always mean it is delivered to that address. Also, I had my car serviced many times at Toyota dealerships and they never informed me of this extended warranty. If I had been made aware of the extended warranty I would've had it repaired in a timely manner. I have spoken to two representatives of Toyota and they stated they could not help me. I'm wondering why this is not considered a recall issue as it does affect the safety of driving a vehicle and the lights stop working. This may not be the right place to ask this question but I'm hoping someone in your organization can help me.

The contact owns a 2010 Toyota Prius. The contact stated while driving at various speeds, the brake pedal would depress to the floorboard initially without warning. Over time, the brake pedal had become stiff upon depression with several warning lights illuminated on the instrument panel. The vehicle was taken to an independent mechanic where a code reader confirmed a defect with the braking system. The vehicle was then taken to another independent mechanic where the vehicle was diagnosed with a defective brake booster. The mechanic then informed the contact of NHTSA Campaign Number: 13V235000 (Service Brakes) which was linked to the failure. The dealer was notified of the failure and informed the contact that the vehicle was not included in the recall. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 153,000.

Prius Gen III has a known defect with failing Brake booster parts. In Nov 2023, while driving my 2010 Prius (~160K miles), suddenly brake, ABS, Traction control, skid indicator lights popped up on the dashboard and I have lost the ability to brake effectively. There was a brake pressure loss and I had to slam hard the brakes to slow the car. The error code was 'C1391' and the mechanic diagnosed it as failure of Brake booster parts ABS Brake booster pump (accumulator) - part#47070 47060 and Brake master cylinder (actuator), part#47050-47140 and he replaced both these parts. Toyota is aware of these failures which are very frequent and hence they issued a brake booster “customer service program” ZJB - which extended the warranty for these parts. But many of us were not covered by this warranty either because of the time or mileage restrictions. This was a costly repair and we had to fix it out of pocket at the cost of ~$3000 as this is safety hazard without proper braking. To make matters worse, 3 months after the repair, the newly installed parts failed again and I had to go through the same repair. I called to Toyota to complain about this and they cannot do anything about it and advised me to report it to NHTSA.
