Body problems of the 2021 GMC Sierra 1500

I have a 2021 GMC Sierra 1500 with a power 6-point tailgate. The inner tailgate has been spontaneously opening for some reason. It seems the electric lock mechanism trips. This could case the contents of my truck bed to fall out. This issue is a known issue for GMC sierras and a recall has been issued for the 2500's and 3500's but for some reason not the 1500's even though the tailgate is the exact same. I have an appointment to have the issue serviced at dealership, but since there is no current recall they will not cover the expense.

Gmc1500 sierra pick up truck. Rear tailgate dropped today, 3. 15. 2024. Weather was rainy, tailgate was up at the start of the trip. Contacted gm corp and was told this model 1500 was not part of the recall??.

Tailgate drops without warning, lower button on tailgate doesn't work.

The contact owns a 2021 GMC Sierra 1500. The contact stated while driving 20-30 mph, she heard abnormal noises coming from the trunk of the vehicle, with no warning lights illuminated. The vehicle was taken to the dealer, where it was diagnosed that the dash line had detached from its holder and was rubbing against the frame of the vehicle. The vehicle was repaired, however, the failure persisted. The vehicle was taken back to the dealer who diagnosed that the drive axle, band, and rear pinion needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 420.
