Stalling on other Silverado 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: 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 (6 reports) and the battery (5 reports).
Recalls and investigations
5 recalls on the engine cover the 2020 model year. A recall on the same system isn't always the same failure, so read the defect text.
The transmission control valve may fail and cause the rear wheels to lock up.
The transmission control valve may fail and cause the rear wheels to lock-up.
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.
The fuel pump may be missing a pressure regulator, allowing for over-pressurization of the fuel system.

Should you keep driving it?
This page can't tell you that. 0 of 80 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. How reports land on this sheet.
