Three problems related to brake disc pads have been reported for the 2012 Toyota Prius. The most recently reported issues are listed below.
Various alerts lighted, brakes, abs, anti skid. Lost some braking. . . Too soft and funny like. . . Needed pumping. Cost of repair to replace brake pump system including tha actuator(buster). Brake pads for $3,700 +. At Toyota calesa in puerto rico.
Took car in for service at 40,251. Was told brake pads are at 1mm for both rear brake pads, and that rotors were rusted. Told for safety it should be replaced at this time. There had been no indication that brakes were faulty. No warning lights, no noise, no change in braking sensation. Prior service at 35,397 indicates brakes in good condition with both rear pads at 7mm. Also, no mention of rotor rust. Service done at 30,109 also indicates brakes in good condition with rear pads at 7mm. Multipoint inspection paper for 40k service was not attached to bill. Requested inspection paper for 40,251 service, and all other inspection papers. Car was bought at warren ohio Toyota, and was always taken there for service. Was told no inspection papers are kept longer than 6 months, and they could not provide any information about this cars previous inspections results. The most recent inspection paper was mailed to me. It indicates the rear brake pads were at 0mm and 1mm. A 0mm pad. There was nothing that occurred during driving to indicate the pad was down to metal. I have contacted the warren ohio Toyota general manager and service manager with my concerns over this rapid decline in the braking system with no warning in less than 5,000 miles of driving. Most of the driving I do weekly is highway miles. I have not received any response from the general manager or service manger despite repeated calls and emails. This rapid decline in my braking system with no warning is a serious safety concern. Either my 2012 Prius v has a faulty braking system, or the brakes were fine and Toyota of warren ohio lied about the condition of the brakes.
Purchased Prius v in March 2012, June 2012 took vehicle in for service and to have dealer look into noise coming from rear brakes. Dealer stated they could not hear the noise and saw nothing upon inspection. Noise became more frequent and louder, took vehicle back to dealer and they could hear the noise. Upon inspecting the rear brakes they found rear rotors had abnormal markings in them from improper machining. Brake pad friction material glazed. Rotors and pads replaced. After a week the noise returned. Took vehicle back to dealer and was told this was a problem which Toyota has been experiencing for months but has found no solution too. Was told I would be informed when a solution was found and I could bring the vehicle back then. I feel this is a safety concern which needs to be looked into.
