Consumer Description

Shift to park issue. Vehicle appears to be in park but message appears. You have to continuously wiggle shifter and shut car off and off until it registers it is in park. I have no way of knowing if vehicle is truly in park or not. For safety reasons I cannot park in an incline due to concerns the vehicle will roll backwards. Several TBS bulletins have been issued by GMC on this known issue and they deny any responsibility of fixing the situation with a recall. The NHTSA needs to step in and investigate and require GMC to remedy this dangerous defect
