We were exiting a parking garage when the car suddenly slammed the brakes on in the path of traffic and lost all electrical power. We could not get the car to turn back on or even get it in neutral to move it out of the path of traffic. Our [XXX] old got locked in the car because the car had zero electric power and someone helped us figure out how to unlock the car with the physical key. We were stuck for four hours because no one could figure out how to get the car out of the garage. If this had happened going at a high speed this could have caused a deadly crash, and it happened without any warning.

Engine thermostat defective, which causes the computer to speed up radiator fans, and causes temperature gauge to read zero. Dealer replaced under warranty at 68,000 miles and same problem reoccurred at 90,000 miles. Common problem on Cadillac XT5’s (all years)

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.

The engine just stopped working mid traffics shifted to neutral automatically- almost causing a serious accident on a busy interstate . Brought to the mechanic, readings stated misfiring cylinders as engine seized and slipped. Tried fixing issue for $8300.00. Then after trying to fix it with no luck, cylinder 5 and seven were stuck and could not be repaired. Cost of labor to out engine back together was $4600.00 plus $400 to tow it to a dealer. Not only life threatening but also wallet draining with no warning. Will never buy a Cadillac again. This is a serious threat for those driving in it and for those who come across it when something happens.

While driving the vehicle on 01 May 2025, the car rapidly decelerated from over 60MPH to under 30 MPH in an instant. The car would not go over 30MPH. The power steering was off, the safety restraint was off, service transmission warning was on, engine light was on,low fuel indicator was on (I had over a half tank of gas), and service stabilitrak was on. The car had to be towed to the dealership. This is the second time this has occurred within the last 45 days. I just purchased the car in the middle of March. This is extremely unsafe as if I was on a highway I would be injured, someone else would be injured or death. I filed a complaint on 20 March 2025 (Complaint No: 11649676).

Coffee was spilled on center console while transferring cup from Starbucks employee to cup holder. Cup was overfilled and lid wasn’t on properly. Immediately the dash panel started flashing and the service transmission light came on. Drove around a parking lot for a few minutes and seemed okay to drive even with the instrument panel flashing. Had 90 mile drive and during drive message similar to slow down for gear shift popped up and “Service Shifter See Owner’s Manual” came up. When I went to exit freeway and was around 5 MPH the vehicle slammed to a stop. Then would not go into any other gear. As I called for tow driver I turned vehicle back on and was sitting when the vehicle started moving again without my control. I then drove it an additional 20 miles home staying above 20 MPH. Insane Cadillac would design a $120k vehicle with that risk in a very susceptible to spills area. Incredibly unsafe. Beyond traumatizing experience with a vehicle that has leas than 8500 miles on it.

Engine is stalling as if its choking and whole car is shaking. Vehicle has been up to date in maintenance with 26000. Miles. Now Check engine light is on along with traction control light .

The contact owns a 2015 Cadillac CTS. The contact stated that occasionally while driving at various slow speeds, the message "Driver Assist Unavailable" and the steering wheel was abnormally firm, requiring excess effort to drive the vehicle until the power steering functionality returned. There was no warning light illuminated. The vehicle was taken to a local dealer, where the vehicle was diagnosed; however, the contact was advised that there was no failure found with the vehicle, and the failure was not duplicated. The vehicle was not repaired. The contact referenced NHTSA Campaign Number: 25V175000 (STEERING); as a possible cause for the failure. The manufacturer was not notified of the failure. The approximate failure mileage was 92,000.

Lights became so dim it was impossible to see at night. I replaced the bulbs multiple times with no remedy. I also had the outer shell cleaned which still did not help. I had to finally have the whole assembly replaced.
