One problem related to brake disc has been reported for the 2002 Hyundai Elantra. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2002 Hyundai Elantra based on all problems reported for the 2002 Elantra.
At less than 11,000 miles, my Elantra's front brake rotors had to be turned and machined. New brake pads were also installed. Now at 22,000 the front rotors are warped again and are too thin to machine again. They have to be replaced. We feel these are defected from the manufacturer because of the alloy used in these rotors being poor quality. If a dealership has 40 rotors sets in stock, there must be a heavy demand for these. I am in process of working w/ Hyundai on this issue. This is a huge safety concern.
