GMC Yukon — review
The 2025 refresh turned the Yukon into the full-size SUV to beat — bigger screen, better diesel, a Denali Ultimate that nips at the Escalade's heels. Then you open the hood of the 6.2L and remember which company built it.
What it is: GMC's premium full-size SUV, fifth generation since 2021, Tahoe's fancier sibling. The 2025 refresh was the big one: redesigned interior around a 16.8-inch vertical touchscreen, new Elevation base trim, new AT4 Ultimate (factory off-roader with massaging seats — a combination nobody asked for and everybody likes), Denali Ultimate with 24-inch wheels and executive second-row seating, Night Vision, Super Cruise, and the LZ0 3.0L diesel (305 hp, 495 lb-ft). Same three engines as the Tahoe: 5.3L, 6.2L, diesel. 8,400 lbs of tow.
What's genuinely good starts with the refresh. The 16.8-inch screen finally gives the Yukon an interior that matches its price, and the "2025-2026 GMC Yukon" FB group (22,000 members) is full of people who are genuinely pleased — illuminated badge mods, lift-kit debates, a 2026 Elevation buyer defecting from a Tahoe with 61 comments of welcome. The LZ0 diesel is the drivetrain the informed buyers pick: the group's "3.0 or 5.3?" thread is the diesel fans vs. the V8 traditionalists, and the diesel fans have torque, range, and fuel receipts on their side. The 5.3L remains the rational default. The AT4 Ultimate is a genuinely new idea — luxury off-roader without the aftermarket homework — and the Denali Ultimate's back seat is a better place to spend a road trip than most living rooms.
What's actually wrong: the L87 6.2L is under the same NHTSA engineering analysis as every other GM 6.2L — recall 25V-274 (April 2025) covered 2021-2024 Yukons for rod-bearing and crankshaft defects, and the August 2026 escalation came from 499 post-remedy failures with GM logging ~7,000 similar. Any used 6.2L Yukon needs documented recall completion or it's a non-starter. The 5.3L and 6.2L share the DFM lifter-failure problem — one group member installed a DFM disabler under the dash of his brand-new Yukon and asked the group (and his dealer's service manager) whether it would void the warranty; 37 comments, and the fact that this is a normal question tells you everything about owner confidence in cylinder deactivation. The 10-speed's greatest hits apply here too: November 2024 fluid-leak recall, February 2026 wrong-software re-recall. First-year-refresh niggles are showing: a 2026 Elevation with a rear squeak the owner had to diagnose with kids as ballast, a '26 AT4 showing a buckled rear seatbelt with nobody sitting there (genuinely concerning with kids in the middle row), new-owner A/C noises. CarGurus' own data gives the 2023 a mixed 3.4/5 with transmission and engine-recall complaints called out. And the air suspension on AT4/Denali trims is the long-term question nobody can answer yet — the Tahoe side is already seeing 100k-mile failures.
The social pulse: proud but watchful. The refresh landed — the screen, the badges, the Denali Ultimate are hits. But the mechanical trust conversation never stops: DFM disablers, diesel-vs-V8 threads, and the 6.2L recall shadow over everything. Nobody in the group is relaxed about the L87, including the people who bought one.
Value call: used averages run about $42,800 (2021) to $74,900 (2025) per CarGurus this month — steep, and the 2025s hold hard because the refresh is that good. The play: a 2025 Elevation with the LZ0 diesel is the value move (new interior, new tech, best engine, outside the recall window); the Denali Ultimate if the budget stretches. A 2022-2023 5.3L in the high-$40s to mid-$50s works with full service history. Cross-shop the Tahoe (same mechanicals, less money, less nice inside), the Ford Expedition (fresh generation, no engine scandal), and the Lexus LX if your budget has truly left the reservation. Skip 2021 (launch year + full recall population), any 2021-2024 6.2L without paperwork, and be picky about 2023s — the transmission complaints cluster there.
The tradeoff, straight: the best big luxury SUV GM makes right now, powered by an engine menu where two of the three choices come with asterisks. Pick the diesel, enjoy the 16.8 inches of screen, and never think about rod bearings again.
