2022 Cadillac XT4

The contact owns a 2022 Cadillac XT4. The contact stated that while driving at an undisclosed speed, the vehicle was shaking and lost motive power. The messages "Service Stabili-trak" and "Intake and Exhaust Valve To Optimize Performance And Efficiency, Please Schedule Service Now" were displayed. The vehicle failed to restart. The vehicle was towed to the dealer, who performed an unknown repair, but the failure persisted. The vehicle was towed back to the dealer; however, the cause of the failure could not be determined. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

The digital instrument cluster will at random times go dark while driving. Took car to the dealership and they say there is no recall or service bulletin. This has happened so many times and i lose speedometer, fuel level and all other critical information all while driving. This is a safety issue and should be something done to resolve this as its dangerous.

When backing up the vehicle, the front brakes squeak as if the wear sensor is engaging. The noise goes away and does not reappear for the remainder of the drive cycle. I took it to the dealer and the pads are not in need of replacement. The service writer stated that it is a 'characteristic' of the vehicle and GM is aware of the problem. They have not issued a service bulletin for this. They also refuse to replace any parts relating to this problem. A search of the internet reveals this is a common problem with XT4's over several years. A simple solution appears to be to lubricate the pads where they seat into the caliper.

I purchased this car used in early 2024. Shortly after buying it, the brakes began squeaking while backing out of the garage in the morning. This is the only time day this occurs. It has been a constant complaint since. I took it to Suburban Cadillac in Troy, Michigan where I purchased the car. They said it is a characteristic of the car and GM is aware of it. Their only suggestion was to spend $1,800 to replace all four brakes and rotors. This causes anxiety as the noise is the same as if the brakes are worn out. The shop at the dealer checked the pads and they all had 8 to 9 mm left. Also, the mileage on the car is about 22,000 miles.
