The front brakes on our Hyundai Sonata failed 9/17/15 forcing my daughter off the road using the emergency brake. This is a result of on-going brake problems dating back to when we purchased this certified pre-owned car 11/25/13. Hyundai refused to cover the repair, so we paid to have brake pads, rotors and calipers replaced. This is the 3rd set of brakes we've paid to replace in less than 12,000 miles. After numerous calls and correspondence with Hyundai consumer affairs explaining this is a life threatening problem caused by defective brake system, they did pay for the calipers but refused to pay for the other components. The front brakes had grinding noise since we bought the car and only lasted 2,743 miles (dealer told us this cpo car had brand new brakes), the second set only lasted 9,856 miles. Since the caliper was replaced 9/21/15, there is no more grinding. It seems clear that the defective caliper caused the pad and rotor failure, but Hyundai denies this. When speaking with Hyundai consumer affairs, they said 1)they had no record of us owning the car, 2) had no recalls for this problem, and 3) we did not purchase an extended warranty (we did). I subsequently found on the hntsb website that there is a recall for the 2011 Hyundai Sonata brakes (attached) involving the brake calipers. Hyundai has been dishonest and deceitful during this ordeal. I would to file an official nhstb complaint against Hyundai to 1) prevent other catastrophic brake failures and potential fatalies, 2) obtain reimbursement from Hyundai for the cost of repairs ($1,085. 68, receipts attached) + inconvenience/time/punitive damages. Attached are copies of correspondence, repair orders, nhtsb recall, etc. Thank you for any help you can provide. Ron corsello 412-427-1113 (mobile).
