Model Years Affected: 2002, 2003


Front catalytic converters are prone to cracking along the seams of the converter itself. Most repair shops can successfully weld the seems to prevent exhaust leakage.

  • Check engine light came on right after picking up car from dealer for recall repairs. Looked up diagnostic code which said it needs catalytic system repairs
