2024 Cadillac XT4 Complaints

FORWARD COLLISION AVOIDANCE — Filed 02/17/2026

Automatic emergency braking activated on three separate occasions when there weren’t any reasons for it to engage, additionally if there were any cars behind me I would have been rear ended since they would not have anticipated me stopping so suddenly.

STEERING,SUSPENSION — Filed 05/22/2026

The vehicle has a chronic defect causing rapid, repeating front-end suspension and steering assembly failures. The right front strut and mount failed and were replaced under warranty twice in 2025 (at 29,968 miles and 35,740 miles). In May 2026, the left front strut and mount failed and were replaced. Two days after picking up the vehicle, a cascading mechanical failure occurred when the left front CV axle boot split, covering the wheel well in grease and requiring a complete CV axle shaft replacement. Following these consecutive teardowns, the dealer omitted a mandatory safety wheel alignment. The vehicle was returned with a severe lateral steering pull and a steering wheel forced to the 1 o'clock tracking position while driving straight, causing extreme handling instability on public roads. The manufacturer refused to authorize a warranty alignment to fix this safety hazard, forcing an out-of-pocket expense at a separate facility to make the car safely drivable.

FUEL/PROPULSION SYSTEM — Filed 06/22/2026

Vehicle died leaving the doctor's office due to faulty fuel pump driver control module. Upon research found that this has been an ongoing issue for several years affecting many GM vehicles. Vehicle can stall at any time in traffic causing serious injury or death. Apparently GM does not have a fix for this problem & the company's solution is to replace the faulty module with modules that have the same defects. Also, when affected vehicles stall in traffic, the parking brakes set & there is no way to even put the vehicles in neutral so that they can safely be moved out of the roadway. This increases the chances of causing a serious accident if one was not caused by the initial breakdown. GM should not be allowed to sale these vehicles with faulty parts putting countless lives in danger.

FUEL/PROPULSION SYSTEM — Filed 06/11/2026

I was getting out of a parking lot with my 3 kids and the car shut off right in the middle of the entrance/exit of the lot blocking anyone from coming in or out. The car would not go into neutral to move it, making it unsafe for my family and everyone around us. We tried to charge the battery but that did nothing. We called tow truck then where told we need a special tow truck since the car could not be put into neutral. We waited hours for a tow truck, when we finally go there, the car's emergency breaks keep coming on and would not turn off. We ended up removing the battery. I was told that it was the Module fuel Pump shorted out, it was a common issue. I asked how we could put the car in neutral and he stated that there is no way to put the car in neutral when this happens, which is a safety issue. This should be a recall. I have the app that is supposed to alert me if there are any issues, nothing showed until after the call shut off, even then all it said was that the battery was low followed by an issue with the fuel management system.

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.

FUEL/PROPULSION SYSTEM — Filed 04/17/2026

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!

SERVICE BRAKES — Filed 05/05/2026

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.

ELECTRICAL SYSTEM,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE — Filed 02/03/2026

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.

FUEL/PROPULSION SYSTEM — Filed 01/10/2026

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.

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

I WAS STOPPED AT A RED LIGHT, IT TURNED GREEN AND I PROCEEDED TO DRIVE FORWARD THROUGH THE INTERSECTION WHEN ALL OF A SUDDEN THE AUTOMATIC BRAKING SYSTEM ENGAGED BRINING THE CAR TO AN IMMEDIATE STOP IN THE MIDDLE OF THE INTERSECTION. MY PASSENGER AND I WERE THRUST FORWARD INTO THE STEERING WHEEL AND DASHBOARD RESPECTIVELY. THE CAR BEHIND ME HIT ME. BOTH CARS SUSTAINED DAMAGE. THERE WAS NOTHING IN FRONT OF ME THAT SHOULD HAVE CAUSED THIS SAFETY SYSTEM TO ENGAGE.I BELEIVE THEY CALL THIS PHANTOM BRAKING. BECAUSE I HAD JUST STARTED UP FROM THE LIGHT, MY SPEED WAS SLOW AND WE SUSTAINED NO INJURIES. HOWEVER IF THAT HAPPENED ON THE FREEWAY I TRAVEL QUITE FREQUENTLY, I WOULD HAVE BEEN KILLED. I AM SO STRESSED ABOUT DRIVING THIS CAR, I ASKED CADILLAC TO DISENGAGE IT. GM AND CADILLAC BOTH DID INSPECTIONS AND CADILLAC SAID THERE IS NOTHING WRONG WITH THE BRAKING SYSTEM. I DON'T UNDERSTAND THE GM REPORT AND HAVE ASKED FOR AN EXPLANATION. MY UNDERSTANDING WHEN I BOUGHT THE CAR LAST YEAR WAS THAT THE "SMART SYSTEM" WAS FOR FORWARD EMERGENCY BRAKING FOR VEHICLES AHEAD NOT BEHIND THE CAR. WHEN I DRIVE OUT OF MY GARAGE AND IT JUST STARTS TO RAIN, THE AUTOMATIC BRAKING SYSTEM ABRUPTLY STOPS MY CAR AND I CANNOT GET OUT OF THE DRIVEWAY UNTIL THE CAR GETS FULLY WET. I WAS TOLD THIS CAN HAPPEN SOMETIMES. I ASKED CADILLAC TO ADJUST THE SENSORS AND THEY SAID THEY ARE NOT ADJUSTABLE. SOMETHING IS TERRIBLY WRONG WITH THIS SYSTEM.
