One problem related to brake disc caliper has been reported for the 2013 Toyota Prius. The most recently reported issues are listed below.
On 07/20/15 the brakes failed completely while driving. On 08/05/16 the same brakes failed again while driving. It is the same issue verified by two Toyota dealerships, (front left caliper and brake pad replacements needed). The car was bought new. The brakes have failed twice, they cite safety defects. On 08/15/16 I photographed left front brake issue. They claim they, "don't know why it's happening. " it is clear the car is unsafe and should be replaced entirely. I reported the first brake failure 07/20/15 the brakes failed while driving. The dealer stated it was a safety related defect that they could not figure out why and thus sent the original brakes to Toyota for inspection & investigation. I never heard back. On 08/05/16 (12 months 15 days later, approx. 12,000 miles driven) the same brake failure happened again. Filled it with brake fluid on 08/15/16 make it to deerfield Toyota (closest) that stated I would have to take it to the original to avoid paying. Very dangerous. Then took to same, eric jones, lipton Toyota, fort laudredale, FL, as last time. He stated the replaced calipers and brake pads were defective. The car remains there, 10 days awaiting a back order. I inquired further on 08/22/16 to which mr. Jones stated the car was bought new with defective brakes/ calipers and that they had replaced them 07/2015 but that they had replaced them with Toyota defective brakes again. (especially specifically the front left caliper and brake pads). Brakes have failed twice. It is clear the defective issue is from the car. Photos reveal that the replacements never resolved the issue as it has been occurring ever since then. To continue driving to see if a 3rd brake failure occurs is to risk mine and others on the road lives. 1st reported safety concern to NHTSA on 07/20/15, reference #10735054 : randy reid. I am scared. Help please.
