5/5 Overall
NHTSA 5-Star Safety Rating
The dominant pattern among 2023 XT6 owners centers on powertrain concerns, with drivetrain and engine performance making up the largest share of complaints. Owners most commonly describe loss of motive power while driving, sometimes with no warning lights beforehand, and the vehicle failing to restart afterward. A recurring fuel system complaint involves engine hesitation and power loss during acceleration, particularly under load or when the engine is warm, often accompanied by a fuel pump performance diagnostic code. A smaller cluster of owners reports back-over prevention system issues, though the specifics in these complaints are limited. One owner describes the steering locking up during a right turn at highway speeds, a symptom that a dealer was reportedly unable to reproduce or diagnose after a two-day inspection.

By System
The 2023 Cadillac XT6 has 3 recalls, the most serious being a transmission defect where the left-front axle shaft can disengage, cutting power to the wheels while driving or allowing the vehicle to roll away when parked.
The remaining recalls are lower in severity. The certification label on the driver's side door pillar may have illegible tire size information, which can lead to the wrong tires being installed and raise the risk of a crash.
