  • 8,200 miles
Bolts fell out of front drive shaft causing drive shaft to become dislodged and hang down striking roadway. Would act as a vault point at highway speed. Minor damage to bottom of vehicle from rotating/ bouncing driveshaft. Dealer installed "an upgraded boltkit" this makes me think this not the first time this has happened if the bolt kit is upgraded.

To state recognition of the facts: Fwd wheel-spin was reported to achieve forward vehicle movement with the current fwd system on wet surfaces of this vehicle. The drivers correction factors to regain traction includes, de-throttle (back peddle the engine) to lower the torque level and thereby hopefully regain traction with the roadbed when the road conditions exist as reported. Reported details to GM and driving experiences driving issues include: 1.cana traction control device be added to retard the throttle and RPM to prevent wheel-spin" 2.are the correct tires / tire compounds being used? 3.will wheel-spin endanger the lifeline and longevity of this transmission or motor? 4.is damage is being introduced into the mechanical parts of the engine and transmission, what can we expect" 5.the current implementations require the driver to functionality drive regaining control of the front tires, which is considered abnormal therefore becoming a hazard to the normal traffic flow as show. 6.the current implementations require the driver to back-pedal the throttle motor and transmission; the observed conditions occur over 2000 RPM of acceleration, next the motor / fwd systems then over-spin the motor and transmission up to 3500 RPM before the driver can back-pedal the throttle, regain control, and resume acceleration while attempting to remain safe in normal traffic flow.. to summarize GM (karen) has reported in a verbal phone conversation with me, held on 12/10/08 that a stabilock transmission on a 2008 Acadia is within specifications to have fwd tire-spin and or traction loss when acceleration exceeds 2000 RPM on wet roads and surfaces and the vehicle handling conditions are normal. Karen also states she has no issues with the reported problems as described, and maybe, I (the driver lacks experience driving a front wheel drive vehicle).

1. while traveling on an interstate highway, the vehicle's "stabilitrak" control abruptly shut down, and the brakes locked with light depressions of the pedal. (stabilitrak controls the vehicle's traction control, anti-lock brakes, and roll-prevention program.) 2. the failure has occurred approximately 5 times; on one occasion, the engine stalled in addition to the above. Consequences were as described above. 3. the vehicle was taken on an urgent basis to the GMC dealer the following day. The dealer advised that the problem is due to "play in the camshaft, " which sends an erroneous signal to the stabilitrak, causing it to shut down. The dealer advised that repair will require replacement of cylinder heads and other equipment, which is a draconian procedure which will take a week or more. In addition, the dealer advised that the problem is causing permanently damage to the vehicle's drivetrain which worsens with miles driven. The dealer further advised that repair parts would not be available for at least 8 weeks because the problem is widespread in the vehicle line and GM refuses to manufacture parts in sufficient quantities to meet the national demand. Almost 8 weeks after reporting the problem, the problem remains unrepaired, and GM has refused one written request and one written demand for immediate correction of the problem, despite this being an immediate threat to occupant safety in that it shuts down the vehicle's most important electronic safety components, including traction control, anti-lock brakes, and the anti-roll-over program.
