In owners' own words
Driving on interstate at 75 mph. Car suddenly lost power and slowed immediately. Had to cross lane in heavy traffic to get to side of road.
In february of this year (2013) the transmission in our 2008 GMC acadia failed while I was driving my two small children home from preschool.
My acadia (Which I just bought in march) began shifting harshly between the 3rd and 5th gears and my check engine light came on.

Recalls for the 2008 GMC Acadia: 5
The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury.
In the affected vehicles, increased resistance in the driver and passenger seat mounted side impact air bag (SIAB) wiring harnesses may result in the SIAB and seat belt pretensioners not deploying in the event of a crash. Failure of the side impact air bags and seat belt pretensioners to deploy in a crash increase the risk of injury to the driver and front seat occupant.
However, there have been new reports of thermal incidents on hwfs modules after this improvement was installed. These incidents resulted from a new failure mode attributed to the device's thermal protection feature. It is possible for the heated washer module to ignite and a fire may occur.
A short circuit on the printed circuit board for the washer fluid heater may overheat the control-circuit ground wire. This may cause other electrical features to malfunction, create an odor, or cause smoke increasing the risk of a fire.
If a buildup of snow or ice on the windshield or on the wipers restricts the movement of the wiper arm, the windshield wiper linkage may become detached from the motor shaft and the wipers may become inoperative. If this were to occur, driver visibility could be reduced, which could result in a vehicle crash.
