Updated November 5, 2026  |  Emich Chevrolet Service, 2033 S Wadsworth Blvd, Lakewood, CO 80227  |  Service (303) 986-2241

If you drive a 2021-2024 Chevrolet Silverado 1500, Tahoe or Suburban with the 6.2L V8, your truck may be part of one of GM’s largest recent engine recalls, and federal regulators are still looking at how well the fix is working. Here is what the recall covers, how to check your VIN in a minute, and what the free inspection at Emich Chevrolet involves.

Which Chevrolets are included

The recall also includes the GMC Sierra 1500, Yukon and Yukon XL and the Cadillac Escalade and Escalade ESV with the same engine. Trucks and SUVs with the 5.3L V8, the 2.7L TurboMax or the 3.0L Duramax diesel are not part of this recall. The fastest way to know for sure is your VIN.

How to check your VIN

What the free recall repair involves

Under the remedy GM filed with NHTSA, the dealer inspects the engine first. If the inspection finds a problem, the engine is repaired or replaced as needed. If the engine passes, the technician switches it to a higher-viscosity engine oil and installs a new oil fill cap, a new oil filter and an updated owner’s manual insert. The higher-viscosity oil matters after the visit too: use the oil GM now specifies for your truck at every future oil change.

The latest: NHTSA is reviewing the fix

An Engineering Analysis doesn’t automatically mean a new recall is coming, but it is a sign to stay current. If your truck already had the recall work, keep using the specified oil, keep your service records, and check your VIN again every few months.

What to do if your engine sounds wrong

Don’t wait for a letter if you notice warning signs such as a new knocking or ticking noise, an oil pressure warning, a check engine light, rough running or a loss of power. Stop driving when it’s safe and call us. Engine failure at highway speed raises the risk of a crash, which is why GM classified this as a safety recall.
