2024 Cadillac XT4 Complaints

Problem with the fuel pump control module. Car broke down in front of my neighbor’s house. Now there is a problem with the transmission. It is slipping and there’s a clunking noise.

Had three different incidents: 1st occurrence was at a red light and vehicle stalled and would not restart. Jumped the vehicle and went on my way. 2nd time was traveling at 40 mph and engine killed. Jumped it again and it started. 3rd time vehicle was parked and would not start. Had it towed to dealership. They determined it was a bad fuel pump power module. This is a dangerous reoccurring issue with the Cadillac XT4 which demands a recall!

High-pitched squeal under light braking at low speeds (under 10 mph), typically occurring during the first few stops of the day...Dealer stated TSB Numbers: 20-NA-002 or MC-10232149-0001 only refers to 2020 model year. Please update this TSB so it includes 2024 model year XT4 vehicles. Dealer unable to replace break pads and charge GM without updated TSB. Note: Issue has been ongoing since purchase of vehicle and both dealers in Michigan (where purchased) and Indiana stated humidity. Recently, Indiana dealer (Lockhart Cadillac Fishers) got more and more vehicles back so now believes it should have a TSB to fix due to noise caused by semi metallic pad issue. Dealer charging $469.78 to apply anti squeal to pads which they know is only a temporary fix (so not recommending it). Dealer cannot help unless GM acknowledges issue.

While driving on the highway at approximately 65-70 mph the Automatic Emergency Braking system engaged for no apparent reason, no vehicles were around or near our vehicle. The sudden and unexpected braking could have cause a major accident resulting in serious injuries or worst had our vehicle been rear ended.

Car suddenly stopped while driving and would not start and stalled. Tried to restart multiple times with failed to restart. Car cranked but did not start after multiple attempts. There were no warning signs or indication before stall. Luckily, incident happened in parking lot way out from it. Traffic behind had to steer to other lane to maneuver. Stalling on public road or freeway could’ve been a safety concern for occupants and others. Dealer diagnosed the issue as faulty fuel pump driver module and replaced the part. Issued was fixed under vehicle manufacturer warranty.
