In owners' own words
While I was driving vehicle it failed to accelerate as necessary between the speeds of 35-50 mph. It has continued to do this .I'm sure it is because of the transmission.
While on an on-ramp to an interstate, my wife was merging into fast moving traffic. As she accelerated and merged into traffic, the vehicle lost the ability to accelerate causing the engine to rev and the vehicle to lose speed.
Transmission has become defective on the vehicle, not sure of the extent because it is currently in the shop.

Recalls for the 2008 Buick Enclave: 6
The driver's air bag inflator may explode during deployment, due to a manufacturing defect. An inflator explosion may result in sharp metal fragments striking the driver or other occupants, resulting in serious injury or death.
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.
