Before you message the seller, know the documented failure patterns, repair cost exposure, and risk level for the 2025 GMC Sierra.
What to watch for on the 2025 GMC Sierra
L87 6.2L Bearing Failure Recall
GM recalled a very large number of 6.2-liter L87 trucks and SUVs over connecting rod and crankshaft bearing failures that could seize the engine without warning. Remedy involved inspection, engine replacement where needed, and a heavier oil specification. Verify by VIN before purchase.
DFM Lifter Collapse and Camshaft Damage
Dynamic Fuel Management carries the same collapsed lifter and wiped camshaft risk as the older AFM system, and is well documented on 2019-2021 trucks. Cold-start ticking and misfires are the warning signs.

2025 GMC Sierra price ranges
The 2022 refresh transformed the interior and is the clearest dividing line in this generation's pricing. The 3.0 Duramax inline-six is the quiet standout: economical, smooth, and free of cylinder deactivation. On any 6.2, confirm the L87 recall status by VIN before discussing price.

GMC Sierra (T1XX, 2019+) Buyer's Guide
DFM Lifters, the L87 Recall, and the Duramax Six
The T1XX Sierra arrived for 2019 with a larger body, the MultiPro tailgate, an available carbon-composite bed, and eventually a much improved interior after the widely criticised 2019 to 2021 cabin was replaced in the 2022 refresh. It is the most capable and best-equipped Sierra yet, and it carries forward the cylinder deactivation problem in a new form.
DFM replaced AFM, and the underlying issue did not go away. Dynamic Fuel Management can deactivate cylinders in many more combinations, and collapsed lifters and camshaft damage remain a documented failure, particularly on 2019 to 2021 trucks.
The L87 recall. GM recalled a very large number of trucks and full-size SUVs fitted with the 6.2-liter L87 V8 over connecting rod and crankshaft bearing failures that could cause the engine to seize without warning. Affected vehicles received inspection and, where required, engine replacement, along with a switch to a heavier oil grade. On any 6.2-powered T1XX, verifying recall status by VIN is the single most important check.
The bright spot: the 3.0-liter Duramax inline-six diesel is smooth, economical, and well regarded, and it avoids cylinder deactivation entirely.
What to look for: Confirm all recalls by VIN, particularly on a 6.2. Listen for cold-start ticking on any V8. Check that infotainment software is current. The 2022 refresh interior is a substantial upgrade and worth the premium.
About the T1XX
The T1XX GMC Sierra arrived for 2019 with a larger body, the genuinely useful MultiPro multi-function tailgate, an available carbon-composite bed, and a much improved interior after the widely criticised 2019 to 2021 cabin was replaced in the 2022 refresh. Cylinder deactivation carried over in a new form as Dynamic Fuel Management, able to deactivate cylinders in many more combinations, and with it the same collapsed lifter and camshaft damage risk documented particularly on 2019 to 2021 trucks.
The most important check concerns the 6.2-liter L87 V8. GM recalled a very large number of trucks and full-size SUVs fitted with that engine over connecting rod and crankshaft bearing failures that could seize the engine without warning, with the remedy involving inspection, engine replacement where required, and a switch to heavier oil. Verifying recall status by VIN is essential on any 6.2-powered example. The bright spot in the range is the 3.0-liter Duramax inline-six diesel: smooth, genuinely economical for a full-size truck, strong for towing, and free of cylinder deactivation entirely. The 2022 refresh is the clearest dividing line in this generation's pricing and is worth paying for if interior quality matters.

Frequently asked questions
Should I avoid the 6.2 because of the recall?
Not automatically, but check the VIN and find out exactly what was done. A truck that was inspected and cleared, or that received a replacement engine, is a known quantity. One where the remedy was never performed is not, and that is the situation to avoid.
Is the 3.0 Duramax a good choice?
It is arguably the best engine in the range for most private buyers. It is smooth, genuinely economical for a full-size truck, tows well, and avoids cylinder deactivation entirely. It costs more to buy and diesel maintenance is pricier, but the long-term picture is attractive.
Is the 2022 refresh worth paying for?
If interior quality matters to you, clearly yes. The 2019-2021 cabin was the truck's most criticised aspect and the refresh addressed it comprehensively with better materials, a much larger screen, and a redesigned layout. Mechanically the trucks are similar.
Does DFM fail as often as AFM did?
Reports suggest it is a continuing rather than a resolved problem, and 2019-2021 trucks feature prominently in complaints. The failure mode is the same: a collapsed lifter that can damage the camshaft. Listen at cold start and ask about oil consumption and any lifter work.
