• 12/27/2020· VEHICLE SPEED CONTROL

  CAR HAS TWICE ATTEMPTED TO ACCELERATE WHEN NOT GOING VERY FAST AS IF IT WAS ATTEMPTING TO GET BACK TO WHAT THE CRUISE CONTROL WAS SET FOR. CRUISE CONTROL WAS NOT ON AND I HAVE NEVER USED IT SINCE I PURCHASED THE CAR. IT DOES NOT WANT TO STOP ACCELERATING WHEN I TAP THE BRAKE AND HAVE HAD TO BRAKE SEVERAL TIMES TO GET THE ACCELERATING TO STOP. BOTH TIMES I WAS IN TRAFFIC BUT NOT GOING VERY FAST AS I WAS ACCELERATING FROM BEING STOPPED AT LIGHT. THERE WAS NO ACCIDENT AS I WAS ABLE TO GET THE VEHICLE UNDER CONTROL AND EVENTUALLY TO HAVE THE ACCELERATING STOP. I TRIED TO CALL THE CADILLAC CUSTOMER SERVICE NUMBER BUT WAS UNABLE TO GET THROUGH DUE TO THE HOLIDAYS. I INTEND TO TAKE IT TO SERVICE PLACE TOMORROW TO CHECK IF THE THROTTLE MIGHT BE DIRTY OR DEFECTIVE BUT AM WONDERING IF THERE MIGHT BE SOMETHING WRONG WITH THE SOFTWARE CONTROLLING THE FEATURES OF THE CAR.

• 12/09/2025· SERVICE BRAKES

  Brakes failure. Approaching a busy intersection and facing a red light, I slowed and prepared to stop the vehicle. Nothing happened with regard to braking; instead, the engine seemed to rev up as it continued through the red-lighted intersection with 2 lanes of busy cross traffic from both directions. That there was not a collision is a miracle. I also noticed some flashing displays on the display screen, though hard to take time to read them while avoiding a crash and still trying to stop the car, but I believe they referenced "parking assist." My husband came and drove the car to the dealership (about 3 mi.), and during that drive, there was no braking issue but a Parking Assist readout suddenly appeared, and he was able to return the screen to the map; then a few minutes later, while driving under 20 mph near the dealership there was a notice about "maximum speed" being reached and "parking assist" being somehow reactivated. Vehicle currently at dealership for analysis. Side note: this is our second Cadillac to exhibit this problem -- there should be an NHTSA report on the first (April 2025) -- a 2013 SRX, in which there was a parking lot collision that totaled the vehicle.

  When I get on the freeway and go around 68 mph my vehicle starts shaking and I constantly get a stabilitrak message that flashes on and off. I have to hold the steering will tight because it swerves a little and had to start driving away from cars. I took it to get the wheels balanced and it still does the same thing. The mechanic from the dealer ship I purchased the vehicle from said he could not find anything wrong with it.

  I received a Steering Assist is Reduced message and the cooling fan ramped up to full speed. In contacting Cadillac, it seems that it is a below temperature error for the thermostat. Unsure what the thermostat has to do with steering. Also in researching this, this is a wide spread issue and needs to be a recall. My XT5 has 48000 miles on it and the powertrain warranty expired 3 months ago. I believe this should be a recall and should be repaired by the manufacture as it could cause a safety issue while driving.

  When driving the car on Jul 20, the check engine light came on. It went off upon arriving home. We had it checked at our local NAPA Auto Care and they did an Electronic Engine Control Test. The garage did not clear Trouble Codes and advised us to take the car to a dealer. Upon driving the car on Jul 30, the check engine light came on once again. In May 2020, when we had our car in for service, at Sutliff, in State College, PA, they took care of the Engine Control, software issue. This dealer is no longer open so we started taking our car to Blaise Alexander in Altoona, PA We, also, have had several incidents with the Parking Brake not releasing. We took the car to Blaise Alexander, in Altoona, on 3-14-23, and they said that the software showed no problem with the Parking Brake. They advised me to call a tow truck and have it towed into their garage the next time it happened. There is a Cadillac Dealer in Ebensburg, PA which is approx 30 miles away. We are in a dilemma as to have it towed there or have it towed to the GM Dealer in Altoona, PA which is approx 16 miles away. Our car has 50, 813 miles on it. I will have it towed either to the Cadillac dealer or the GM dealer.

  My 2018 Cadillac XT5 has a serious water intrusion issue—water is leaking into the interior cabin through the sunroof or roof seams. This appears to be the result of a known manufacturer defect covered in GM’s Technical Service Bulletin TSB 19-NA-167. The leak has caused significant water accumulation on the floor, raising concerns about mold, electrical failure, and corrosion. I brought the vehicle to a Cadillac dealership, and they confirmed the issue. The total repair estimate is around $7,900. Cadillac offered partial goodwill coverage, but I am still being required to pay $3,400 plus tax out of pocket. I have authorized the repairs but am seeking reimbursement for the portion Cadillac is not covering, as this is not normal wear and tear—it is a clear defect in manufacturing that poses safety and health risks. GM should be fully covering this issue for affected vehicles.

  After exiting a car wash (automated)on Monday-7/3/23, I was attempting to stop my vehicle so I could dry the exterior with towels. I was on the car wash property and as I approached an area that was open, I attempted to stop the vehicle, the engine revved very high and the vehicle took off at a very high speed in fractions of a second. The vehicle then climbed over a flower embankment and hit the wall of the Car wash. The impact was so great that it put a large hole in the wall and ruptured a main water line creating a huge water leak. The fire department and police officer arrived at the scene to make a report. My initial thought was that my sandal may have got trapped but after returning home and rethinking the entire incident may times I believe this was “UNINTENTIONAL ACCELERATION “ The driver side airbag and knee airbag were deployed. Thankfully I was not hurt. Had this happened when I was on a road or a grocery store/ mall parking lot things could have been very serious. I have insurance through State Farm and have requested them numerous times to have a diagnostic check done to identify the reason for this to happen and they have declined my request. Please let me know what the next steps are.

There were no exterior causes for this...just a release of pressure that was inherent in the window from manufacturing. there was no other damage to the vehicle. i was on a wooded part of the road, so nobody was around to throw an object, and there was no vehicle in front of me to kick up some sort of road debris.

  Thermostat failure causes steering assist to be reduced. This leaves more difficult steering especially in an emergency situation, thus a safety concern. The vehicle displays a warning: "Steering Assist Is Reduced, Drive with care". An internet search shows this is a well-known problem across all General Motor vehicles.

  During the two years we have owned this vehicle, it has completely shut down. It usually happens when the vehicle is stopped or coming to a stop. Today 4.17.2023 it happened at 67 mph as I was accelerating to highway speed. The vehicle shut down for 2-3 seconds then restarted. The vehicle decelerated very hard, almost as if it were in a collision.
