| Description of the problem | i have owned the car since november of 2012. Beginning in q1 of 2014, i began to notice the brake pedal feeling spongy in the car. Over the next several months, the pedal became even more spongy, where the brakes would not engage sufficiently to slow the vehicle until the pedal was depressed past more than 2/3's of its full travel. Took the vehicle into the dealer for service on 6/4/2014 with 19,627 miles as vehicle is under warranty and no one else wants to work on it as it would void my warranty. I described the problem to the dealer. The dealer completed their tests and stated that brakes were operating normally. I then took the mechanic for a drive to show that the brake pedal went to almost the floor and again told this was normal by the dealer mechanic. Approximately a month later, after leaving the car parked for a week at the airport with the emergency brake engaged, the rear driver wheel began thumping and vibrating immediately upon driving out of the parking space. I stopped the car and examined the tire. No problems with the tire were detected so i drove home. The noise decreased during the drive but did not go away. The car was then taken to a tire shop where tires were swapped and problem remained with the same left rear brake. Another appointment is scheduled with hyundai dealer to re-examine brake system. The problem with the spongy pedal has increased and now the brake pedal can be depressed to the floor without much effort. Additionally, the left rear brake continues to make noise when the vehicle is in motion. The noise is more pronounced when the brakes are used, but the noise still exists even when the brakes are not in use. |
