These vehicles have an issue of poor fuel pump control module moisture resistance, which, after wading, may cause moisture to intrude into the module and thereby trigger anomalies. In extreme cases, loss of power could occur when the vehicle is driving, posing a potential safety hazard. SAIC-GM will replace improved fuel pump control modules for these vehicles free of charge to eliminate the safety hazard.
