Had a new catalytic installed in a 2003 Elantra under warranty at 70, 000 miles. At 90, 000 miles I was told I needed a new catalytic converter at a cost of 1400.00. I contacted Hyundai and was told that the warranty ended at 80, 000 miles even though it was supposedly a brand new catalytic converter. If I had it installed at 79, 999 miles and it malfunctioned at 80, 001 I would be out of luck. read full review »
