Common Issues
- Fuel pump module failure. The fuel pump driver control module fails, causing the engine to stall or the vehicle to fail to start. Failures occur both while driving and when the vehicle is parked. No warning lights illuminate before shutdown.
- Unexpected stalling. Vehicles abruptly lose power and come to a stop while traveling at normal speeds, creating dangerous situations in traffic.
- Multiple failures. Some owners report repeated issues with the fuel pump control module, with failures occurring multiple times within a few years of use.
- Battery replacement needed. In some cases, the fuel pump module failure diagnosis includes replacing the battery to restore operation.
- Sunroof shattering. At least one report describes the sunroof glass exploding on a hot day without any external cause or debris.
The XT4 has two recalls affecting occupant safety systems. These recalls concern rear seat belt retractors which may have been improperly secured. The defect could compromise seat belt performance in a crash.
Recalls
- Rear seat belt retractors. NHTSA recall number 21V649000 affects 402 vehicles including 2019-2021 Cadillac XT4s. The rear seat belt retractors may have loose or missing fasteners, leading to improper function during a crash and increased injury risk. Dealers will inspect and tighten fasteners free of charge. Owner notifications were mailed in September 2021.
Owners facing repeated fuel pump control module failures or dealing with unresolved recall repairs may have rights under state lemon laws. Consulting with a consumer protection attorney can help clarify options for addressing persistent safety and reliability problems.

Fuel pump module failed twice. There was no warning lamps, messages or other symptoms prior to the failure. The first time I was driving the second time the car was parked and did not start. See below for details. Safety: Thankfully i was not driving 70+MPH down a busy highway when the car shut down. Given the past recall, the number of Cadillac owners experiencing the problem and that it's happened to me TWICE within three years, it's only a matter of time before serious injury or death occurs. First time: [XXX], Milage: 15,063 i was driving down a small-town highway doing 55 when the car stopped working. All power went off, no acceleration, difficulty steering. I was able to safely get to a side road. Had it towed to local Chevy dealer for repair. They diagnosed the issue: Bad fuel pump driver control module. Second time: [XXX], Milage: 34, 6112 The car was parked at my house and failed to start. Had it towed to local Cadillac dealership for repair. They diagnosed the issue: Bad fuel pump driver control module. Additional information I've found a previous recall on the fuel pump module from 2021 on Cadillac SUVs [XXX] I've found many forum posts of Cadillac users experiencing the same problem. This is just one link for XT4 and the last post from a user with the exact same problem was March 6, 2025, and another on Feb 4, 2025.
