What owners wrote
“Rear tailgate does not open and sometimes will show a warning on the dash that the tailgate is open when it is not. The tailgate for the heavy duty 2500/3500 trucks were recalled for the same reason but not the 1500 trucks. This is a common issue on the truck forums and is an unsafe condition.”

“I washed my truck and now suddenly the tailgate opens and closes whenever it decides and I have paint that is bubbling and it looks as if itâs gonna all chip right off the hood”

“The tailgate on my 2021 Chevrolet Silverado 1500 opens randomly. Initially, it was not often, but progressively happening. I had to pull over in rush hour traffic this morning to shut the tailgate after it opened randomly. The only reason I knew, was checking the rear camera.”

Should you keep driving it?
This page can't tell you that. 0 of 26 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
