Stalling on other Sierra 1500 years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2016, 2018, 2025.
What this problem usually is
Stalling reports are some of the most alarming on the site. The engine quits while the car is moving, sometimes on a highway and sometimes at a stop. Many owners say it restarted right away and the dealer found no stored code, which is part of why these complaints pile up before anything gets fixed.
What got replaced
Owners who name the part that was replaced mention the engine (15 reports), the battery (6 reports) and the fuel pump (3 reports).
Recalls and investigations
2 recalls on the engine cover the 2019 model year. A recall on the same system isn't always the same failure, so read the defect text.
One of the driveshaft joints may not have been properly welded, causing the driveshaft to separate while the vehicle is moving.
The battery positive (B+) cable rings may have been manufactured with excessive glue, potentially causing an intermittent electrical connection between the B+ cable and alternator.

“I was coming to a stop at a stop a 3 way stop intersection. I parked completely and when I stopped the vehicle just shut down I did not have any warning signs come on prior as I looked at the dash it said place vehicle into park and start. I tried that but truck did not start. Call my friends we towed the truck on a trailer to my house and set up an appointment with gmc here in Tucson az”

“GM installed a 2023 6.2L engine in my 2019 GMC. The engine locked up while I was driving it. It had about 54,000 miles on it. There is a recall on the vehicles with the 6.2 GM engines that were made between 2021 and 2024. However since they installed it in my 2019 they are telling me they won't warrant it because the recall just list the vehicle year and not the motor year. This is not right.”

“Transmission has been failing for the life of this vehicle. Shuttered shifting and hard shifting are the norm. It is available for inspection. Vehicle does not shift properly when vehicle is in motion. Shifting is often delayed resulting in temporary loss of power. I have had the vehicle in to a transmission shop they have been able to reproduce the events. There are no warning lights visible to indicate an issue.”

Should you keep driving it?
This page can't tell you that. 2 of 105 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.
