- Summary
- Isuzu Commercial Truck of America (ICTA) has been receiving warranty part returns that have aftermarket catalytic converters welded in place instead of the OEM catalytic converter. This is because vehicle owners who have had the OEM or Fleet Value catalytic converters stolen from their vehicles often replace the stolen catalytic converters aftermarket with non-Isuzu parts. When those replacement parts fail and cause the check engine light to illuminate, vehicle owners may seek to have the non-Isuzu replacement catalytic converter repaired or replaced under warranty. In fact, however, neither the new vehicle warranty nor the one-year replacement part warranty covers the failed non-Isuzu part.
