Summary

14306 - customer satisfaction. We have learned that certain vehicles equipped with a twin turbo engine (lf3) may have been built with front fascia lower grillettes that do not have air vents. Without air vents, under certain high performance driving conditions, such as race track driving, the engine could exceed 258°f and enter the over-temperature algorithm which will shut off the air conditioning system and begin to reduce engine power. Dealers are to replace the non-vented grillettes with vented grillettes.

Owners of these vehicles have filed 4 complaints in the body category.
