4/5 Overall
NHTSA 5-Star Safety Rating
Engine problems are the dominant story for the 2023 GMC Yukon, accounting for the majority of complaints filed against this model year. Owners most commonly describe sudden, complete engine failure with no warning, the vehicle loses power while driving, sometimes on highways at speed, and cannot be restarted. Several owners describe the engine seizing entirely, requiring a tow. Powertrain complaints, the second most-reported category, often involve loss of propulsion in situations that overlap with those engine failures, suggesting some of the same underlying experience. Electrical system complaints appear at a much lower volume. A separate pattern involves paint blistering along the roofline, above the windshield, and around the sunroof, owners describe it appearing across the full width of the vehicle and spreading toward the rear quarter panels.

By System
The 2023 GMC Yukon has 6 recalls, the most serious involving transfer case faults that can lock front or rear wheels, a 6.2L V8 engine whose internal components can fail and cause sudden engine shutdown, and rear suspension bolts that can break and knock a rear wheel out of alignment.
On the fuel side, certain Yukons equipped with the 6-cylinder diesel engine may have received a replacement fuel tank that does not seal correctly in a rollover, allowing fuel to escape near potential ignition sources and raising the risk of fire. Two lower-severity software recalls round out the list. The brake control module software may fail to display a warning light when brake fluid drops to a low level, meaning a driver could continue operating the vehicle with reduced stopping power without any indication on the dashboard. The lighting control module software may leave the daytime running lights active even after the headlights are switched on, creating glare that reduces visibility for other drivers on the road.
