problem #1

Sierra 1500

The driver's side floor mat will not stay in place because the device that is supposed to hold it in place is broken. The floor mat is now able to move forward and interfere with the function of the brake and/or accelerator. Both the dealership (Castle Rock GMC, Colorado) and GMC Customer Care (Case #: 91-11325687695) have ignored all requests to address this and other issues. I have also written letters to GMC Corporate and the Castle Rock GMC General Manager, both of which were also ignored.
