general problems of the 2009 GMC Sierra 1500

Door panel gets loose over time catching on inside of door frame making it difficult to open a door. This is a safety hazard in the case of an emergency so I removed my door panel completely.

Dash cracked. A known problem for these vehicles.

Transmission control module since the summer of 2020 the vehicle has at least half a dozen times, without warning, experienced the following symptoms (most recently July 27, 2021 when I captured it on video). 1. Power door locks begin cycling open and closed 2. Intermittent chime operation 3. Transmission locks into a single gear and won't shift or will shift harshly 4. Gauges fluctuate 5. Traction control and stabilitrak turn off 6. Service traction control and service stabilitrak messages appear 7. Transmission position indicator disappears.

Train horn at hwy us 1 in bunnell at belle terre is tooo loud daily. This is is between 2200hrs and 0400 hrs daily its too much. It wakes family, baby, wife.

Back up sensors for park assist do not work when a hitch is in the receiver.

I'm having electrical/computer problems that started over a year ago and continue to increase. First, my speakers go off and on as they please. The driver side door speaker is the only one that stays on consistently, and it has nothing to do with hitting bumps or anything else. Second, my power looks have gone out. My key fob will still work them and they still lock and unlock when truck is moved between park and drive. But the buttons on the door do not work. I've replaced all the fuses, and still, nothing. Third, my cruise control is going out. On a long drive I used it for half and then the other half it wouldn't even try to come back on. A few days later it worked again.
