The Problem: According to GM, the transfer case may electronically switch to Neutral without input from the driver. If this happens while a vehicle is in motion, no power will go to the wheels. If the vehicle is stopped or parked, it may roll away if the parking brake is not set. The automaker said it is not aware of any crashes or injuries related to this issue.
The Fix: GM will notify owners and dealers will recalibrate transfer case module software. No notification schedule has been announced.
What Owners Should Do: Owners can call Chevrolet at 866-694-6546 and GMC at 866-996-9463 for more info.
