One problem related to brake disc pads has been reported for the 2008 Hyundai Elantra. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2008 Hyundai Elantra based on all problems reported for the 2008 Elantra.
The rear rotors on my 2008 Hyundai Elantra had grooves worn in with only a little over 37,000 miles on the car. The brake pads on the right rear were worn almost completely while the brake pads on the left rear had enough material left on them to drive another 15,000 miles. I took the car to a nationally recognized repair center for new pads because my brakes started to squeak. . The certified mechanic showed me the pads and the rotors and stated that it is odd for the pads on one side to be worn out and the pads on the other side to have about a year's worth of pad left. The side where the pads that had a year left on them the rotor had substantial groves. The rotor on the side with the worn pads had less damage. He stated the rotors were probably substandard and they were probably made in a foreign country with substandard materiel. I took the car to the Hyundai dealer where I bought the car for their perusal. The supervisor stated that the rotors were worn and the cause was likely a maintenance issue and is not covered under the car's warranty. I contend the problem is defective material and or poor workmenship. I contacted Hyundai customer assistance for help. They also stated this is not covered under the warranty. I believe there might be an issue with the rotors on other Elantra's on the road today and this issue could cause serious injury or worse if it is not addressed.
