2008 GMC Acadia Problems

Vehicles with a 6speed automatic transmission may develop one or more of the following faults related to a broken 35R clutch wave plate inside the transmission: Illumination of the Check Engine Light with code P0716, P0776, P0717, P0777, P2714, P2715, and/or P02723, loss of reverse gear, slipping or harsh 3rd or 5th gear shift. Removal and dis-assembly of the transmission will be required to replace the broken 35R wave plate. It is also extremely important that all debris from the failed part be cleaned from the transmission while it is disassembled in order to try and prevent future problems.

Service brake system message, sometimes Service Stability, red brake light and TRAC OFF message.
These are sometimes the result of low brake fluid, but no obvious leaks are noted. Due to the design of the master cylinder and brake booster, the master cylinder can leak from the rear seal and collect inside the booster, leaving no drops on the ground or obvious signs.

You will need to replace the master cylinder and booster to correct.

A Loose or worn gas cap may cause Check Engine Light to illuminate.

2008 GMC Acadia Questions

Our seat won't move anymore. GMC thinks motor is shot, but whole seat track and motor must be replaced for $900. That seems crazy. Can I get a used motor and track?

2008 GMC Acadia Recalls

Increased resistance in the front seat mounted side impact air bag (SIAB) wiring harness can result in the SIAB and seat belt pretensioners not deploying as expected in the event of a crash, increasing the risk of personal injury. Dealers will replace the affected harness connections with soldered connections to correct this concern.

The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.

If a buildup of snow were to occur on the windshield, the movement of the wipers may be restricted. This could result in the wiper linkage becoming detached from the wiper motor, rendering the wipers inoperable. Visibility could be reduced, increasing the risk of a crash. Dealers will install a new wiper crank arm, driver's side link, and crank arm nut to correct this problem. This recall is expected to begin on October 13, 2008. The General Motors recall number is 08091.

The car had been driven less than 10k miles a year for 5.5 years. It is just 6 months out of warranty and GM is not honoring it. I would not recommend this car to anyone. THIS SEEMS TO BE A COMMON PROBLEM WITH...
