Summary

16186 - Emission Recall. General Motors has decided to conduct a Voluntary Emission Recall on certain vehicles equipped with a 1.8L engine. On some vehicles, cracking of ceramic components internal to the catalytic converter may occur as a result of higher than anticipated exhaust temperatures. If this occurs, the catalytic converter low efficiency diagnostic will set and the malfunction indicator lamp will illuminate. Dealers are to reprogram the engine control module with calibrations that prevent higher than expected exhaust temperatures.

Owners of these vehicles have filed 171 complaints in the electrical category.
