Engine rattle 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, 2020, 2022, 2023, 2024, 2025, 2026.

What this problem usually is

Owners in this group hear something before anything breaks. Most describe a ticking or tapping at idle, a rattle that's worse on a cold start and fades as the engine warms, or a noise that comes and goes over weeks. Some report the check engine light following a while later. It's the early-warning end of the engine complaints, and the reports that end in a named part are useful to anyone hearing the same sound.

What owners wrote

“Lifters (the part that opens and closes engine valves) fail prematurely. There was a loud ticking noises, rough idling. Took to dealership and they advise that yes the lifters are failing and not drivable at this time.”

Filed Jun 30, 2026

“My engine has a loud knocking/ticking noise. I have had one mechanic look at it. He has me taking my truck to a dealership this week. He believes the known issue with GMC's 6.2 engine is taking place in the engine in my 2019. From a verbal conversation with the dealership, they believe the same. I was advised to complete this form ASAP.”

Filed Oct 28, 2025

“Engine has a bearing failure. Just purchased the truck it started to tick so I was being proactive stopped driving the the truck to prevent lock up.”

Filed Jan 19, 2025

“Every time I start the engine I get loud ticking noises. This is Lifter noise! I took it into the Dealership and they said the noise was normal. GM is known for having this Lifter problem in the heads. This can destroy my engine, causing premature wear on the lifters themselves.”

Should you keep driving it?

This page can't tell you that. 0 of 30 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.
