Summary Verdict

The 2023 GMC Yukon XL demonstrates good overall reliability, particularly with its gasoline V8 engines and the standard 10-speed automatic transmission. The most commonly cited technical concerns tend to be related to the optional Adaptive Air Ride Suspension, where compressor failures or air leaks can occur, and potential software glitches within the infotainment system. The Duramax diesel engine, while efficient, has a known potential for Diesel Particulate Filter (DPF) regeneration issues, especially if not driven regularly on highways. Electrical systems, particularly battery drain, can also be an area to monitor. For most owners, the Yukon XL should provide a dependable experience, but awareness of these specific potential issues, especially with the air suspension and diesel powertrain, is advisable for proactive maintenance and cost management.
