Recalls & safety

Whether a recall is still open on a specific car depends on its VIN. Check it free at NHTSA's VIN lookup (nhtsa.gov/recalls), or ask the seller for proof the repair was done.

Pros & cons

Pros

  • Spacious, upscale interior with a vastly improved independent-rear-suspension ride.
  • Strong 6.2L V8, 5.3L V8 and an efficient turbo-diesel powertrain choice.
  • Large displays, available Super Cruise hands-free driving and a premium Denali Ultimate trim.

Cons

  • V8 fuel economy is still poor; only the diesel is thrifty.
  • The 6.2L L87 V8 is subject to a connecting-rod and bearing engine-failure recall.
  • Pricing climbs steeply on Denali and Denali Ultimate trims.
