Summary

14096a - emissions recall (revised service procedure). General motors has decided to conduct a voluntary emission recall involving certain vehicles equipped with a gasoline engine. The oxygen (o2) sensor may fracture if condensation from the catalytic converter enters the o2 sensor and causes a sudden temperature change. If this occurs, the malfunction indicator lamp will illuminate. Dealers are to inspect and, if necessary, replace bank 1, sensor 2 and bank 2, sensor 2 o2 sensors and reprogram the engine control module.

Owners of these vehicles have filed 12 complaints in the engine category.
