The Brake Actuator and Brake Accumulator were covered under a customer support issue until 5/18/22 On our car they are charging me $2600 to fix this issue. The car was at Toyota years earlier for a recall but Toyota never told us about this issue. That is not fair in my opinion. And now we are being charged $2600 to fix this issue Best [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The Brake Actuator and Accumulator on the car have failed Toyota had a customer support issue on these parts and fixed them for free BUT it expired 5/18/22 No Toyota dealer told me about this issue and I received no warnings Now the 2012 Prius with 78,000 miles has this issue and Toyota wants $2600 to fix it

the car was serviced regularly and for unknown reason the engine started running rough. I took it the mechanic and after completing a diagnostic test he said i have a blown had gasket in the engine. After reading online about the issue i discovered this year and model of toyota are notorious for having a blown head gasket issue. My mechanic recommended the engine be replaced. This is an expensive repair and toyota is denying any accountability about the issue

My letter to Toyota: I'm writing this in regard to an inverter issue my 2012 Prius C recently experienced. While driving last month my car completely shut down, no warning and thankfully cars avoided hitting me and I was able to get from the middle lane to be able to coast to a side street in which I had to be towed. It turned out it was an inverter issue which had to be replaced. Granted my vehicle has less than 135k even though it is a 2012. I have done research and found models of Prius had the same exact issue(s) which was part of a warranty enhancement and I truly think my vehicle should be included. I want this to be looked in to and addressed. I will be contacting NHTSA also in regard to this. I filed with Toyota and ref#230323001904

The brake had an issue while driving. It was hard to stop the car. It is probably due to the brake booster. I had this issue and I took my car to the dealership and they could not find the problem. I had the same issue again while driving. Luckily, when both problems happened, I drove slowly on the local roads. Toyota had recalled those specific models but the length of the warranty is not long enough to solve the problem. For instance, they gave a second warranty, either 10 years or 150K miles, which hits first. I got this brake problem 6 months later after the warranty expired. But my mileage is low ~118K. For drivers' safety, they should extend the length of the warranty. The two parts are expensive (~4-5K in total) and apparently, that's the problem with the design of the auto parts. Customers should not pay for them and risk their own life.

Driving on Interstate and suddenly traction control light, brake Light, and ABS light came on. After this the brakes were not as affective at stopping the vehicle and felt sluggish. Found a lot of reports online about similar issue and even some when the vehicle brakes failed. My brakes allowed me to get home without incident.

Our 2012 Toyota Prius experienced brake failure due to the Accuator and Accumulator. I contacted Toyota Corporate office, which advised it is a known problem and had a customer support program that expired last year. The Toyota rep advised me to not drive the vehicle because of the brake failure and opened a ticket advising it is a known issue. After researching online, it is a very common issue. https://www.aboutautomobile.com/Consumer-Complaint/2010/Toyota/Prius/Brake
