Known issues to check on the 2021 Chevrolet Suburban

One widely reported problem pattern applies to this model year. That does not mean this car has the fault — many were fixed under warranty or recall — but it is what to check, and what to ask the seller for, before you buy.

5.3L V8 (Active Fuel Management)Expensive if it bites
The Gen V 5.3 V8 with cylinder deactivation is widely reported for collapsed AFM lifters, wiped camshaft lobes and heavy oil consumption, usually announced by a persistent tick.
What to check: Start it stone cold and listen for a tick or misfire. Ask for oil consumption history and whether lifters or the camshaft have been replaced; an AFM delete or a documented lifter job is a plus, not a red flag.

Patterns are drawn from NHTSA recalls and complaints, manufacturer service bulletins and consistent owner reporting. Always confirm open recalls against the VIN and get an independent pre-purchase inspection.
