Models:
2008 Buick Enclave
2007-08 GMC Acadia
2007-08 Saturn Outlook
2008 Saturn Aura
Condition
Certain 2007-08 model year GMC Acadia; Saturn Outlook; and 2008 model year Buick Enclave; Saturn Aura model vehicles were incorrectly
reprogrammed by dealers/retailers in normal service and under Customer Satisfaction Program 07217A and Service Update 07235A. The TCM
(Transmission Control Module) and ECM (Engine Control Module) both must be reprogrammed with the updated software for correct odometer
operation. GM TIS2Web Service Programming System records indicate some vehicles have had only one of the modules reprogrammed, causing
incorrect odometer function if the vehicle is driven. Attached to the Administrative Message (US) / Dealer Communication (Canada), used to release this
bulletin, is a list, in BAC (US) / Dealer Code (Canada) sequence, of those vehicles which only had one module reprogrammed and which our records
indicate are still in your inventory.
Correction
Dealers/Retailers are to reprogram the stock vehicles listed using the Programming Sequence procedure to assure that both the ECM and TCM have the
updated software. Vehicles which have accumulated mileage with only one of the modules updated must be programmed using the Programming
Sequence and must also have the vehicle odometer reading corrected using the service procedure detailed in this bulletin.
