2023 Cadillac XT4 Complaint Log

Vehicle is equipped with a 9 speed automatic transmission that will not engage (even after dealer re-program/re-learn). Transmission must either be manually shifted to 9th gear by paddle shifter or shifted to manual mode and quickly back to auto for it to shift to 9th gear (fuel efficiency affected). Report twice to dealer with no concern for repair. Incident happens at every use of the vehicle (infrequent times it does work (shifts to 9th on its own)).

Started vehicle in morning and no sound from the infotainment system (even if radio screen is on). Noticed turn indicators sound no longer functioned as well as I believe auto stop function also became non-functional. Safety concern while driving. Had to reset by performing a system re-set/re-boot myself to make everything work again. This issue occurred 2 times in 2 seperate days.

Turn signal canceler not working after making a left hand turn

Auto Emergency Braking {AEB} applies itself without any operator input and without cause for the brakes to engage, it can happen at any time at any speed without warning and throws everyone and everything in the vehicle abruptly forward as if you were in a crash, this is a very problematic issue that can make the vehicle at slow speeds to be rear ended because of the abrupt stop and also to be out of control at high speeds and causing severe injuries or death !!!! I am not the only person that has had this issue !!!!

Driving on freeway, vehicle in front slowed down and my vehicle detected vehicle in front slowing down only slowed, not stopping), so my vehicle immediately braked to a stop on the freeway. Concern vehicles behind me of rear end collision. Vehicle would not allow me to proceed until until my vehicle was at a complete stop. Very dangerous as this could cause injury or death by other drivers not able to react to sudden stop.

Transmission fails to automatically shift into 9th gear. A GM bulletin #21-NA-181 indicates this is normal for efficiency operation, but the information indicated is false. Experiencing 9th gear is allowed to be shifted when manually over ridden or when shift to manual mode (without shifting to 9th gear), then shift back to auto mode, then transmission shifts to 9th gear automatically after this is performed then shift to 9th gear automatically during that cycle until vehicle is turned off. So condition GM claims in their "operating condition" is false.

My 2023 XT4 had a fuel module failure. I was driving along a busy highway at 50 MPH when i lost complete power. Now i see on the Cadillac forum, many people are having problems with the Cadillac XT4. According to the towing company it happens all the times. I also read on the forum other people were told this too by towing companies. This is Dangerous and you could be left in the middle of a intersection and be T-boned. Shame on Cadillac for not caring. We have another XT4 in the household and now are afraid to drive. My car is currently being repaired. so at this time i do not have a repair invoice. Its still at Sheehan Cadillac Pompano Beach fla.

I was driving down the street and the car just turned off. Would not go into gear and said the battery was bad. The exact same thing happened last year they said it was the alternator. Both times my car just power off with no warning while driving down the street

Fuel Pump module failed in middle of a busy intersection that could have caused a major life threatening crash.

The contact owns a 2023 Cadillac XT4. The contact stated while driving at various speeds, the vehicle experienced phantom braking. The vehicle was taken to a dealer however, the failure was not duplicated. The failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 3,000.

Rear back half of sunroof exploded. I removed the glass so it would not fly out and hit other cars or people. It could have been very dangerous if the sunroof was open when it shattered.

The vehicle's transmission does not shift smoothly in the lower gears (1-3) when decelerating. It feels like a clutch is popping and the vehicle 'jerks' when this occurs. This began to occur immediately after purchase and continues to do so today. The vehicle was returned twice to the dealer for warranty service and they stated it was operating as designed. The vehicle currently has less than 5,000 miles.
