UGH .... some definite troubles right out of the gate. GM Quality Control should have caught the windshield issue. The power tonneau cover most likely is temp issue; ice perhaps in the actual enclosure or a motor adjustment issue. I am now second guessing the power cover. Maybe the manual trifold BAK Flip MX4 hard tonneau would be best. Anyone else having issues with the tonneau?? Hang in there Dark-fx..... hopefully the issues are resolved quickly.Last night I went out to test fit some stuff in the bed and the powered cover wasn't cooperating. Didn't think to record a video last night, but it was still doing it this morning, so this time I did.
Took the Hummer back to the dealer this morning to have them address the whistling noise and the cover. They said they would have to get GM involved in fixing it, and GM might decide to send out the tonneau manufacturer for that part. I opted to have them figure out what needs to get done, and drop the truck off once they have a plan in place. If it's just going to sit, I'd rather it sit in my driveway.
