2007-2009 Acadia Transmission Failure

Acadia owners are tired of seeing a shift to park message when their gear shift lever is already in PARK.
A new lawsuit says the problem prevents owners from shutting off or locking their vehicles.
In addition to losing the ability to shut off and lock the SUVs, owners claim they must resort to all kinds of theatrics to get the SUVs to recognize they are in PARK. Drivers also say the batteries drain and GM has no clue how to fix the issues.

On September 13, 2015, Rayven Barfield parked her 2001 GMC Yukon in a driveway. She turned the ignition switch off, but left the keys in the ignition.
Later she heard someone screaming as the the SUV rolled away with a child in the driver's seat. What happens next is unimaginable.
