| Description of the problem | Vehicle started to make a heavy grinding noise from passenger side rear wheel. Closer inspection revealed a fresh gouge in the rotor. Took the car to the dealer where the vehicle was purchased and was informed that this was a normal wear and tear item, and not covered under warranty (even though a "gold" warranty had been purchased with caliper replacement plainly included). This indianapolis dealership wanted to charge $380 to replace the rear brake pads and rotors. An independent repair shop found that the drivers side of the rear had approximately 40% of the life left on the brake pads and only normal wear to the rotor, while the passenger side was worn down to the metal on the pads and had rendered the rotor unserviceable. It was also noted that the wear indicator on the passenger side was broken, and did not give the normal audio warning of excessive wear. When asked why the rear should wear out faster than the front (which is what all local brake shops told me would happen), the hyundai service manager did not have any reply. It should be noted that there are several instances of similar failures, and even a class action lawsuit filed in new york state for the exact same issue. A sticking brake caliper is suspected, but could not be confirmed. Rear brake pads, rotors, and hardware were replaced at my expense. The brake caliper was cleaned, lubed, and reinstalled. Dealership would not honor any warranty obligation for this defect. Front brakes also showed at least 40% of their life remaining on the pads. |
