GMC Sierra 1500 — review
The Denali tax buys you the nicest interior in the half-ton class and the exact same engine investigation as the work truck. The Sierra is a great truck with a branding problem — the branding being the 6.2L V8.
What it is: GMC's premium twin of the Silverado 1500 — same T1 platform, same powertrains, but the Denali, AT4, AT4X, and Denali Ultimate trims are the whole point. The 2022 refresh brought the proper interior (13.4-inch screen), and 2027's new V8s will keep cylinder deactivation, because GM has decided the lifter debate is over and your opinion was not required.
What's genuinely good: the interior is the segment's benchmark at Denali money — quiet, well-finished, with the MultiPro tailgate still the cleverest party trick in pickups. The engine menu's quiet picks are the same as the Silverado's: the 2.7L TurboMax (310 hp, 430 lb-ft) is the low-drama workhorse, and the 3.0L LZ0 Duramax diesel (305/495) is the one the forums recommend to people they like. The AT4X is a genuinely capable off-roader from the factory, not a sticker package. Tow ratings and bed utility are class-competitive, and the 2022+ cabin finally matches the Denali price tag.
What's actually wrong is under the hood of the expensive ones. The L87 6.2L recall (NHTSA 25V-274, April 2025) covers 2021-2024 Sierra 1500s — 153,630 Sierras in the US alone, part of the 597,630-vehicle program with 28,102 field complaints, 12 crashes, and 12 injuries. The P0016-inspection remedy (new engine or thicker oil) didn't end it: NHTSA's January 2026 recall query became a full engineering analysis in August 2026 on 499 post-remedy failures, with GM reporting ~7,000 similar. Open today. Then there's the 5.3L's DFM lifter failures — "goes in batches" is the dealer consensus per the truck press, and one documented 2026 owner had a lifter failure two weeks after purchase, a full engine replacement, then a bad fuel injector a month later. A third complaint on his own truck. The 10-speed got the November 2024 fluid-leak recall (461,839 vehicles, possible rear-wheel lockup) and the February 2026 re-recall because 1,055 trucks received the wrong remedy software — a sentence that writes its own jokes. The Sierra EV side is early-adopter theater: a Denali owner at 60,000 miles with a failed front drive unit ($8,000, thankfully inside the 100k warranty), another owner whose replacement truck — the first was bought back — threw a fault at 2,250 miles in a Costco parking lot, and A/C failures making the rounds. "Praying for 8 years of no major problems," wrote one new Edition 1 owner. Same, buddy. Same.
The social pulse: Denali pride fighting mechanical anxiety. The owner groups are heavy on build posts and light on answers — the promo noise in the big Sierra groups is bad enough that the EV owners' group (3,000 members) is currently the most honest Sierra feed on Facebook. The lifter threads on the forums have the weary tone of people who've read them all before. Nobody's happy that 2027 keeps DFM, but the aftermarket disabler industry is thrilled.
Value call: used averages run about $35,400 (2021) to $50,800 (2025) per CarGurus this month — a consistent $3k-$5k premium over the equivalent Silverado for the badge and the interior. Whether that premium is worth it depends on whether you sit inside your truck more than you look at it. The play: a 2025 with the LZ0 diesel or 5.3L, outside the recall window, with service records. Cross-shop the Silverado (same truck, cheaper, identical risks), the F-150 Lariat (the 2.7L EcoBoost is the rationalist's pick), and the Ram 1500 Tungsten (nicer than the Denali inside, newer Hurricane six, shorter track record). Skip 2021 (COVID lifter batches, pre-refresh cabin) and every 2021-2024 6.2L without documented, completed recall work.
The tradeoff, straight: you're paying extra for the nicest version of a truck whose flagship engine is under federal investigation. Buy the diesel or the little turbo, and the Denali tax feels like money well spent. Buy the 6.2L and you've paid a premium for the privilege of worrying.
