2023 Cadillac XT4 Complaints

POWER TRAIN — Filed 02/28/2026

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)).

FORWARD COLLISION AVOIDANCE — Filed 06/15/2025

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.

ELECTRICAL SYSTEM — Filed 02/24/2026

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.

SERVICE BRAKES,FORWARD COLLISION AVOIDANCE — Filed 07/17/2025

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 !!!!

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.

FUEL/PROPULSION SYSTEM — Filed 03/19/2025

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.
