2018 Cadillac XT5 Complaint Log

While driving at highway speeds, I needed to accelerate hard in order to pass another vehicle and while accelerating there was a downshift and increase in RPM. After passing, the RPM remained high even after I took foot off accelerator and it seemed the transmission did not shift back out of lower gear, keeping the car traveling at a high rate of speed, endangering myself and other traffic. Applying the brakes would not cause the engine to slow down and the engine kept working hard and traveling fast, causing strain on the brakes to slow down. I pulled over and initially shifted to neutral, but the engine was still revving high (4000 rpm observed). Then I placed the car in park which did not change the high RPM. Then I shut off engine and let it rest. Then I turned auto back on and all was normal. The problem has not yet been reported to dealer but will occur in coming days. There were no prior symptoms, problems, or warning lights on dash display prior to this occurring.

My windshield has a lot of spider and has never been hit with anything. They spread from the bottom up

To Whom It May Concern,I am writing to formally report a safety concern involving my 2018 Cadillac XT5, VIN [XXX] . Recently, my vehicle displayed a “Steering Assist Reduced” message on the dashboard while driving. This warning significantly increases the physical effort required to steer the vehicle, especially at low speeds, and I believe it presents a genuine safety hazard.Upon taking the vehicle to an authorized Cadillac dealership, I was informed that the vehicle had stored diagnostic trouble code P0128 (Engine Coolant Temperature Below Thermostat Regulating Temperature). The dealer explained that a malfunctioning thermostat caused the steering assist reduction message to appear. However, at no point did the vehicle illuminate a Check Engine Light, despite the presence of an emissions‑related fault code.I am concerned for several reasons:A critical engine fault (P0128) did not trigger a Check Engine Light, leaving me unaware of any underlying issue. The vehicle reduced power steering assist as a result of an unrelated thermostat malfunction, creating a sudden and unexpected increase in steering effort. This behavior poses a safety risk, particularly in situations requiring quick steering response or low‑speed maneuvering.Cadillac has issued Service Bulletin 17NA158, which acknowledges that thermostat or coolant‑temperature‑related issues can trigger steering assist warnings. This suggests the manufacturer is aware of the problem, yet no recall or corrective action has been issued.Given that steering assist reduction directly affects vehicle control, I believe this issue warrants investigation. A driver should not lose steering assist because of a thermostat fault, nor should a vehicle fail to illuminate a Check Engine Light when a diagnostic code is present.I respectfully request that NHTSA review this matter to determine whether a safety‑related defect exists in the 2018 Cadillac XT5 and similar GM vehicles. Sumitting this for my mother. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

The contact owns a 2018 Cadillac XT5. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to coast to the shoulder of the roadway, where the vehicle failed to restart. While attempting to restart the vehicle, the vehicle required several attempts before restarting. After the vehicle was restarted, the vehicle returned to normal functionality, but the failure became a regular occurrence, prompting the contact to discontinue driving the vehicle. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The contact was advised to take the vehicle to the dealer for assistance. The failure mileage was 40,000.

While waiting at a light, then the car shut off. Lossing all power. I could not get out of the vehicle, no hazards, no lights, nothing. After several pulls of the door handle I was able to open the door but the hazard light was not able to come one. After 4 attempts to engage break to push start the vehicle on ethe brake locked up and would not disengage. Total screen black out, no power no hazards. After some time, the brake released screen activated and I was able to press the brake and try to start the car again. It did not work but was now able to turn on hazards. After 15 mins, I tried again and it cranked up normal. I had new battery in June 2025 and 60K Maintenance services in Aug 2025. This happen in Oct 2025.

Cadillac XT5 had a “steering assist is reduced” message on the driver information center. P0128 Code

Message on dashboard "steering assistance reduced drive with caution". Messages appeared April 2025 and July 2025. Previously electric module needed to be replaced. Steering message caused me to be very cautious. Radiator had to be replaced because of leak. Both issues repaired at dealership. Vehicle has less than 40,000 miles.

The contact owns a 2018 Cadillac XT5. The contact stated that while stopped at a stop light, the front driver's side seat independently moved forward and backward. The contact stated that the driver's side rearview mirror independently folded inwards. No warning lights were illuminated. The contact stated that the failure was persistent and scary.

The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was unknown.

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.

Rear toe arms are malfunctioning barely drive vehicle on 54342 mileage on vehicle. Having to do with steering jeopardize Leicester on my and my family. VMy vehicle has been inspected. This issue has been inspected by Cadillac mechanics and indicated needs immediate attention. No indicator lights were illuminated to inform me of danger. I am impalled about this situation and I shouldn’t be charged for this mechanical default.

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.

The coolant thermostat was broken and gave two check engine codes P0128 and P0128P. AC was not functioning when the thermostat was not working, which can be dangerous in summer. It is also a very common problem with Cadillac XT5 and GMC Acadia.

The tread is separating from the tire in chunks. Never seen this in a 21000 mile factory Michelin tire let alone any other tire before. It exposes the core of the tire which is a safety hazard. Called Michelin and they were only concerned about the warrantee, not the safety.

The contact owns a 2018 Cadillac XT5. The contact stated that while driving at slow speeds, the vehicle unintendedly shut off. The vehicle was towed to the local dealer who diagnosed that the body control module (BCM) had failed and needed to be replaced. The contact was informed that BCM failure was caused by internal corrosion to the unit due to condensation leaking from the HVAC water line, which was positioned above the BCM. The vehicle was repaired. The contact stated that the BCM unit was previously replaced due to the same failure. The manufacturer was notified of the failure. The failure mileage was 95,000.

Passenger side seat bolts attaching seat to frame loosened and seat began to rock

Check engine light (power reduced steering drive safely) notice came on. Code reads P0128, coolant below thermostat regulating temperature. This is an on going issue with Cadillac. It’s definitely a defect because if you go on YouTube you will see it’s not just my vehicle even on low miles vehicles. Then you are left with no choice but to get repaired at the dealer only to be ripped off. 180 for diagnostic testing at dealer to find out this is an ongoing issue across the US

A/C stopped working. Steering assist is reduced warning light came on. Was told it was a thermostat/ sensor. Had the sensor replaced for a cost of approximately $230.00. Short while later, A/C stopped working again. Suddenly the Steering wheel malfunctioned while driving on the interstate. Ran off the the road into median and heard a loud "Pop" sound as I tried to gain control of the vehicle. Hit an embankment and almost crossed over median into oncoming traffic. All airbags deployed. My passenger and I suffered injuries including broken bones, fractured ribs, severe back and shoulder pain, bleeding forearm, bruises and swelling. We were transported to a nearby ER by ambulance. The Vehicle was totaled.

Dash alert: Steering Assist is ResucedDrive with Care I see this is a current problem with the 2018 Cadillac XT5 but my VIN doesn’t seem to be included. Please investigate why mine would not be included if I suddenly have the same issue.

I was driving on the freeway, came to a stop as traffic increased, then the car shut off m. I had no power, could not get out of the vehicle, no hazards, no tail lights, nothing. I had a complete panic attack, I thought I was going to die. I called OnStar from my cell, they could even locate me. After 30 mins, calling 911, texting the representative from the dealership in which I purchased the car, it turned back on. Either the car was shut off with a signal or there is a serious hazardous issue that needs to be addressed.

I was having some routine maintenance done on my car and a popping sound was heard around and under the front of my car. The the car displays a break light in the display and the fault code C056E is now constantly present in the computer. My vehicle is not showing a recall but I know this problem. Is a recall on other similar year and models.

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.

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.

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.

Driving down the road and my 2018 Cadillac XT5 started on fire for no reason and no engine lights came on. I loss all driving control power steering in the matter of seconds and was trapped in the car waiting for cars to clear so I can run out. The car is with my insurance company the car is now a total loss and I don't think they will investigate. I called GM to make a complaint. The fireman said he had just put a fire out on the same car a week ago. I found out that we have 2 more cars in the Macomb county MI area that caught on fire in the last 3 months same type of car.

The contact owns a 2018 Cadillac XT5. The contact stated that while driving at an undisclosed speed, the driver's and passenger's rear wheels locked up, causing the driver's and passenger's rear tires to roll backwards. The contact stated that the ABS failed to operate as intended. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was unknown.

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)

The rear camera guidelines on my 2018 XT5 Lux don’t appear on the backup camera display when shifting into reverse. Happens around half the time. As soon as I shift into drive, the guidelines then appear. I can then shift back into reverse and the guidelines are there.

The contact owns a 2018 Cadillac XT5 equipped with Michelin Tires, Tire Line: Touring H/T, Tire Size: 235/55/R20, DOT Number: B9AJ00TX2017. The contact stated that while his wife was driving 35 MPH, the rear driver's side tire had a sidewall blowout. The contact's wife was able to drive to a tire dealer. The dealer replaced all four tires. The manufacturer was made aware of the failure and informed the contact that the tires were not covered under warranty. The failure mileage was unavailable.

Transmission While at a red light/complete stop car will jerk out of nowhere for no reason. It also did it while driving down hill at a steady speed of 70 mph. Could have been a bad accident if a big rig or other vehicles would have been behind me.

The contact owns a 2018 Cadillac XT5. The contact stated while the vehicle was stationary at a traffic light, the Stabilitrak warning light was illuminated for a short time and turned off when depressing on the accelerator pedal. The contact stated that on 11/19/2012, while his wife was driving 45 mph, the reduced steering capacity, pull over immediately and other multiple unknown warning lights were illuminated. The driver stated that the steering wheel became difficult to turn however, the driver was able to continue driving to her residence. The contact towed the vehicle to the local dealer, where it was diagnosed with needing the battery to be replaced. The vehicle was repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 32,000.

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.

The contact owns a 2018 Cadillac XT5. The contact stated that after coming to a complete stop, the vehicle lost motive power. After restarting the vehicle, the vehicle would operate as needed. The failure occurred on multiple occasions. The cause of the failure was not yet determined. The local dealer and manufacturer were not yet notified of the failure. The failure mileage was 40,000.

The accelerator on the car started to excel and shift in traffic where I had to pull over. Over the last few months the car has had some electrical issues with the braking and collision alerts going off and the car stopping which the dealer said they couldn't find the problem. Also the brakes since purchasing the vehicle has had to be switched out several times and now the parking brake light is on after being repaired 2 times. This car is definitely unsafe and the dealer insist it is.

while driving my vehicle, the rear portion of the sunroof suddenly just exploded, with the glass completely shattering. it sounded like an explosion. 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.

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.

TWO ISSUES INVOLVING THE BRAKES. FRONT BRAKE PADS SQUEAK WHEN MOVING SLOWLY, ESPECIALLY IN THE MORNING OR WHEN MOVING IN A DRIVE THROUGH LINE. THE SECOND IS THE BRAKE PEDAL LOSES PRESSURE OVER NIGHT OR EXTENDED PERIODS OF NON-USE. IT DOES NOT OCCUR EVERY NIGHT. BRAKE PEDAL IS DIFFICULT TO PUSH TO START THE CAR.

TIRES ON GM VEHICLES, INCLUDING MINE, HAVE BEEN SOLD WITH DERELICT TIRES MANUFACTURED BY MICHELIN. I WAS RECENTLY TOLD THAT MY TIRES WOULD NOT PASS INSPECTION AR 26,000 MILES. TODAY I WAS TOLD BY A RELATIVE THAT THEY WERE TOLD THE SAME AND THEIR TIRES HAVE ONLY 16,000 MILES ON THEM. WE HAVE BOTH BOUGHT NEW TIRES THROUGH THE DEALERSHIP UNDER A DISCOUNTED PLAN BY GM BECAUSE OF THIS ISSUE. I FIND IT ABSURD AT ANY COST THAT I WOULD BE RESPONSIBLE FOR THIS MONETARY RESPONSIBILITY DUE TO THE MANUFACTURER OF THE TIRES AND GM KNOWING OF THE POOR QUALITY OF THESE TIRES. WHY WEREN'T WE ADVISED OF THIS TIRE ISSUE AT POINT OF PURCHASE ? THIS SEEMS LIKE A 'SCAM' TO RIP OFF THE CONSUMER.

I WAS STOPPED BY A ROAD CREW. THERE WERE 3 CARS IN FRONT OF ME AND AS I WAITED FOR THEM TO LET US THROUGH ABOUT 10 CARS WERE STOPPED BEHIND ME. I WAS LISTENING TO THE RADIO WHEN I HAD THE WEIRD SENSATION THAT I WAS GOING BACKWARDS INSTEAD OF BEING STOPPED. I LOOKED AROUND, REALIZED I WAS GOING BACKWARDS AND WENT TO HIT THE BREAK BUT MY CAR HAD ALREADY HIT THE CAR BEHIND ME. THE MAN IN THE CAR BEHIND ME TOLD THE POLICE OFFICER THAT RESPONDED THAT HE DID NOT SEE BACK UP LIGHTS OR ANY INDICATOR THAT THE CAR WAS IN REVERSE. I DIDN'T TOUCH THE GEAR SHIFT. THERE IS NO REASON FOR THE CAR TO GO IN REVERSE. THE PHOTO BELOW SHOWS THE DAMAGE DONE TO THE CAR MY VEHICLE HIT.

The contact owns a 2018 Cadillac XT5. The contact stated while driving at various speeds, the vehicle stalled. The contact stated all of the warning lights were illuminated on the control panel. The vehicle was taken to the local dealer on three different occasions where it was diagnosed with nothing needing to be replaced. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 80,264. Consumer stated vehicle completely shuts off and on without no codes or error messages.

2ND TIME THIS ISSUE OCCURRED. 1ST TIME WAS IN 2019 AND IT TOOK TWO WEEKS FOR THE DEALERSHIP TO FIGURE OUT IT WAS THE BATTERY. WHILE DRIVING THE CAR, THE ELECTRONICS GO CRAZY, THE ENGINE STOPS FOR A SPLIT SECOND, BRAKES ARE LOST FOR A SPLIT SECOND, CRUISE CONTROL TURNS OFF, EVERY POSSIBLE ALARM DISPLAYS ON THE DASH. THE DASH BEEPS, ALL OF THE LIGHTS FLASH, THE SPEED/PRESSURE/TEMPERATURE NEEDLES GO TO 0, THE AIR CONDITION TURNS OFF, ETC. ALL OF THIS OCCURRED WHILE I WAS DRIVING 60MPH ON A HIGHWAY. I QUICKLY PULLED OFF TO THE SIDE OF THE ROAD. SINCE THIS HAS OCCURRED BEFORE, I TOOK OUT MY PHONE AND TURNED ON THE VIDEO. I STARTED DRIVING AGAIN AND THE SAME ISSUES ABOVE STARTED OCCURRING AGAIN. THE VIDEO IS TOO LARGE TO UPLOAD - 90MB. I CAN SEND A ONEDRIVE LINK IF NEEDED. *TR

The contact owns a 2018 Cadillac XT5. The contact stated that while driving at various speeds, the steering power reduced warning message was displayed. The manufacturer was notified of the failure and referred her to the local dealer for assistance. The contact was also informed that there were no recalls on the vehicle. The vehicle was not repaired. The contact had not experienced a power steering failure in spite of the frequent illumination of the message being displayed. The failure mileage was unknown.

SEVERAL MONTHS AGO, AFTER WAITING IN LINE FOR TWO MINUTES WITH THE TRANSMISSION IN D AND THE VEHICLE IDLING, I STARTED TO DRIVE FORWARD. SUDDENLY THE VEHICLE CAME TO A SHUTTERING STOP. APPARENTLY THE TRANSMISSION SHIFTED ITSELF INTO P. RECENTLY THIS HAPPENED AGAIN BUT IT OCCURRED WHEN I WAS BACKING OUT OF MY GARAGE. I AM CONCERNED THAT THIS SELF SHIFTING INTO P MAY OCCUR WHEN I AM TRAVELLING AT SOME SPEED AND RESULT IN AN ACCIDENT. I HAVE BEEN TO MY LOCAL CADILLAC DEALER BOTH TIMES AND THEY SAY THE VEHICLE IS SAFE AS IS. BUT I AM CONCERNED.

PARKED IN PUBLIC PARKING LOT. AFTER STARTING CAR AND ATTEMPTING TO BACKUP, CAR WOULD NOT MOVE. PARKING BRAKES WERE LOCKED. TRIED NUMEROUS TIMES TO RELEASE BRAKES. PARKING BRAKE WOULD NOT RELEASE. CAR WOULD NOT MOVE FORWARD OR BACKWARDS. HAD SAME ISSUE WITH 2013/XTS AND 2014/XTS BUT TURNING CAR ON/OFF WOULD RELEASE BRAKES ON THOSE CARS. THIS TIME, HAD TO CALL TOW TRUCK. WEATHER SUNNY, TEMPERATURE 33F. CAR JUST RECENTLY RECEIVED MILEAGE MAINTENANCE. WARRANTY SERVICE FOR BRAKES TWICE SINCE PURCHASING THE CAR.
