When I turn on the vehicle, it will have no sound - audio, turn signal, and most importantly and concerning, seatbelt warning chime. the electrical issues also extend to the hvac sustain have been trying to get this resolved with two dealerships and Cadillac directly for 1.5 almost 2 years. The issues began about three weeks after my lease began. Cadillac directly and the dealerships have done nothing to resolve this and have continuously kicked it down the road with no resolution. I am not comfortable driving a vehicle in which seatbelt deatures are compromised.

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.

Safety restraint warning light came on. Took to dealership. They had for 3 days claimed it was repaired. Light came back on 2 days later. Dealership has now had my vehicle 10 days, stating I need a new side drivers airbag. They do not know when it will arrive. I have seen other complaints in this model for faulty airbag sensors/units.

Driving down the highway yesterday, I believe that the sunroof on my Cadillac XT4 exploded. It was a hot day and I heard a loud bang. My sunroof shattered and no rocks or other external debris to be found.
