5/5 Overall
NHTSA 5-Star Safety Rating
Powertrain and backup/rear-vision complaints dominate what 2020 XT6 owners report. On the powertrain side, a recurring theme involves the engine coolant thermostat opening at a lower temperature than expected, which triggers the check engine light, a "Steering Assist is Reduced" warning, and elevated cooling fan activity. Owners describe this pattern appearing repeatedly, sometimes after the powertrain warranty has expired, making it a notable cost concern. Transmission roughness also shows up across multiple reports, with owners describing jerking and hesitation significant enough to prompt repeated dealership visits for the same underlying issue. The backup/rear-vision complaint cluster ranks close behind, suggesting camera or sensor reliability is a consistent friction point for owners in that area. A smaller number of electrical system complaints round out the picture. On the tire side, at least one report describes tread separation at low mileage on original equipment tires, though that appears to be an isolated report rather than a pattern.

Total Complaints
By System
The 2020 Cadillac XT6 has 5 recalls, the most serious being two separate issues that can cause the engine to stall or the vehicle to lose propulsion without warning, raising the risk of a crash. A fuel pump nozzle can become blocked and starve the engine of fuel, while a transmission component with missing bolts can leak transmission fluid and eventually cause the vehicle to lose drive power entirely. Two recalls involve the side curtain airbags: the inflators may not deploy properly in a crash, and a diffuser component inside the roof-rail airbag inflator can separate during deployment, both of which reduce protection in a collision. On the visibility side, vehicles equipped with the optional Surround Vision feature may have a rearview camera that fails or cuts out intermittently, reducing what the driver can see when backing up.
