One problem related to brake disc pads has been reported for the 2012 Toyota Camry. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2012 Toyota Camry based on all problems reported for the 2012 Camry.
Our 2012 Camry se had approximately 66,000 miles when the brake problem occurred. I was the driving vehicle on the highway on 7/30/18 going 55 mph when I heard an whistling sound for 2-3 minutes. When I arrived at my destination 10 miles from my home I smelt a burning smell which seemed to come from the left rear wheel. When I touched the wheel it was very hot and would have burned my hand if I left it there. I drove home later and the same thing occurred. I threw some water on it and a cloud of steam arose. I called my mechanic who said it was most likely a stuck disc brake caliber and that he had seen the problem before on 2012 & 2013 Camrys. The mechanic diagnosed the problem as a seized caliber piston which required the replacement of the left rear caliber, pads and rotor for over $500. 00. My concern is that I have never had a safety problem like this occur in any vehicle never mind a fairly new Camry which passed a safety inspection at Toyota as part of an oil change on 2/20/18 when the vehicle had 63,253 miles. In my opinion there is a defect in the design or in the quality of the brake system which could lead to a brake system fire or brake failure.
