Consumer Description

THE VEHICLE 4WD SYSTEM REMAINS ENGAGED AND WILL NOT DISENGAGE. UPON FURTHER INVESTIGATION THE SYSTEM EFFECTS STEERING AND DRIVABILITY. ALSO EFFECTS SPEED OF THE VEHICLE. THE VEHICLE UTILIZES A CODE C0398 AND SHOW A MESSAGE OF THE DASH SERVICE 4WD. THIS IS DUE TO FAULTY SOFTWARE INSTALLED BY THE MANUFACTURER. WILL CAUSE DAMAGE TO MECHANICAL PARTS IF DRIVEN ON THE VEHICLE AND IS A SAFETY HAZARD. GM REFERENCE # ISSUED TO ME WHEN ISSUE COMPLAINT OF THE OUT OF POCKET COST TO UPDATE THE SOFTWARE AS REQUIRED BY GM TO FIX THEIR OPERATING SYSTEM. MY REFERENCE NUMBER IS 9-5058496526. SAME ISSUE RESULTED IN 2015 GMC SIERRAS THAT CAUSED GM TO ISSUE A SERVICE BULLETIN #28770. SOFTWARE ISSUES ARE NOT WEAR AND TEAR COMPONENTS. GM FAULTY SOFTWARE IS THE RESPONSIBILITY OF THE GM AS THEY CAN CAUSE SAFETY AND DAMAGE TO THE MECHANICAL PARTS OF THE VEHICLE.
