Fuel and propulsion issues dominate the 2021 XT4 complaint picture. Owners most commonly describe the vehicle stalling or failing to start, with the fuel pump control module identified as the culprit in multiple reports. These shutdowns tend to happen without warning lights or any advance symptoms, and several owners report the failure recurring after an initial repair, one owner describes the module failing twice, once while driving and once while the car sat parked. A single report describes the airbag system and one mentions an electrical concern, but neither shows a clear pattern at this volume. The stall-and-no-restart scenario is the most consistent thread, with dealers in several cases replacing the fuel pump control module and battery to address it.

By System
The 2021 Cadillac XT4 has two recalls, the more serious being rear seatbelt retractors that may be held in place with loose or missing fasteners, which can cause the belt to fail to restrain an occupant in a crash.
The second recall involves the automatic headlights, which may not switch on quickly enough as daylight fades, reducing how well the vehicle is seen by other drivers and how well the driver can see the road ahead.
