Summary

35460 - customer satisfaction program. Some vehicles equipped with a duramax diesel engine (rpo lml) may have a condition in which the intake air heater’s field-effect transistor could generate excessive heat if the system voltage exceeds 13.5v. This heat can cause a short circuit in the transistor and, in rare cases, a fire in the vehicle’s engine compartment. Dealers are to reprogram and update the glow-plug control module with new software which limits the intake air heater input voltage to 13.5v.

Owners of these vehicles have filed 228 complaints in the engine category.
