Engine failure 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: 2014, 2015, 2016, 2017, 2018.
What this problem usually is
These are the reports nobody wants to file. The engine started knocking or ticking, the oil light came on, and then it seized or had to be replaced. Some owners had the replacement covered under warranty or an extension, and plenty were told they'd pay. Several narrower sheets split this group into knocking, seized engines and rod bearing failure.
What got replaced
Owners who name the part that was replaced mention the engine (110 reports).
Recalls and investigations
One recall on the engine covers the 2023 model year. A recall on the same system isn't always the same failure, so read the defect text.
The connecting rod and/or crankshaft engine components may have manufacturing defects that can lead to engine damage and engine failure.

“Start engine light came on while driving. The truck did a dead stop in the middle of the road. Tried to restart but nothing. A tow truck was called and the truck was dropped off at the local GMC dealer. The next day the dealer called me and told me I need a new engine.39,000 miles”

“Our truck had just passed 60,000 miles when the engine seized. The recall procedure was completed in January, and the engine passed the test at that time. We were also using the recommended 0Wâ40 oil. Despite following all guidelines, the engine still failed. This shows that the procedure GM has outlined is not sufficient to determine whether an engine is actually in good condition.”

“Based on the critical recall and safety concerns for this known issue for the 6.2 L87 Engine failure I am highly concerned that it takes over 171 days to just get an appointment to look at this issue. This is further compounded by the fact I put approx 800-1000 miles a week on my truck and now am worried about having an accident or blowing my truck up.”

Should you keep driving it?
This page can't tell you that. 1 of 114 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.
