2020 Cadillac XT5 Problems

On April 8, 2026, my 2020 Cadillac XT5 experienced a sudden and complete engine failure while I was driving. Prior to the failure, there were no warning lights, no overheating indications, no abnormal engine noises, and no performance issues that would have alerted me to a developing problem. Without warning, the engine failed and the vehicle immediately lost power, creating a serious safety hazard. The vehicle became inoperable and had to be towed. Fortunately, I was not traveling on a freeway or in heavy traffic at the time of the failure. Had this occurred at highway speeds or while crossing an intersection, the sudden loss of propulsion could have significantly increased the risk of a crash. This unexpected loss of power increased my risk a potential highway hazard. The vehicle was subsequently inspected and diagnosed by an authorized Cadillac dealership. The dealership determined that the engine suffered an internal mechanical failure, including rod bearing failure and metal contamination throughout the engine. The dealership advised that the engine required complete replacement. The vehicle has been properly maintained and serviced. There was no owner misuse, neglect, overheating event, or other known condition that would explain such a catastrophic failure. The engine failed unexpectedly and without any prior warning to the driver. I am submitting this complaint because a sudden engine failure resulting in immediate loss of power presents a significant safety concern. I believe NHTSA should investigate whether similar failures have occurred in other 2020 Cadillac XT5 vehicles and whether a manufacturing or design defect may exist that could place other drivers at risk.

The contact owns a 2020 Cadillac XT5. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly shifted into different gears. The Check Engine warning light was illuminated. The failure persisted while the contact's wife was driving, and the vehicle lost motive power. The vehicle was able to restart and shift into gear. The contact notified Carvana of the failure and was referred to several independent mechanics, who informed the contact that they did not service vehicles purchased from Carvana. The vehicle was taken to the dealer, who determined that the brakes and rotors, front control arms, radiator, unknown sensors, and several other unknown parts needed to be replaced; however, the contact stated that the recommended repairs were not related to the failure. The vehicle was towed to the residence. Carvana was contacted again and referred the contact to the second dealer, Herb Chambers Cadillac of Warwick (1511 Bald Hill Rd, RI-2, Warwick, RI 02886), who determined that the computer was not communicating with the key fob, and the coolant sensor, the air conditioner, and several other unknown parts needed to be replaced; however, the dealer informed the contact that they were unable to file a claim with Carvana to repair the vehicle. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 68,000.

The contact called on behalf of her grandmother who owns a 2020 Cadillac XT5. The contact stated while driving approximately 60 MPH and attempting to accelerate, the vehicle failed to accelerate while attempting to switch lanes. The contact stated that while depressing the brake pedal, the vehicle was revving; however, the vehicle failed to slow down as needed. The contact stated that the vehicle continued to accelerate to approximately 80 MPH. The contact depressed the brake pedal for an excessive amount of time to significantly reduce the speed of the vehicle. The contact stated that the vehicle decelerated to approximately 70 MPH. The contact became aware that the cruise control had activated independently. While attempting to deactivate the cruise control, the cruise control failed to deactivate. The contact pressed the START/STOP button to turn off the vehicle. The contact pressed the button again immediately turning the vehicle back on and shifting into neutral, significantly reducing the RPM. The contact coasted to the side of the road and turned off the vehicle. After waiting for a while the contact turned the vehicle back on and continued driving. There were no warning lights illuminated. The vehicle was taken to the dealer; however, the dealer was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

After a rainy highway speed 50 mile trip I stopped to get a Lotto ticket at my local store. I shut the vehicle off. It took me approximately 2 to 3 minutes to buy the Lottery ticket. I started the vehicle and noticed that my power steering was not operating. I could barely move the steering wheel ( it seemed locked) and I barely made my 10 mile trip to my house using secondary dirt roads . I called my dealer and was told that sometimes after an overnight of non use the problem would go away. The next morning I started the vehicle and the power steering was back to normal. I took it to my local Cadillac dealer and they scoped it and found no defect codes recorded. I was very fortunate that the incident didn’t occur while driving at I-75 . At high speeds without steering it would have resulted in possible multiple serious injuries or deaths. I hope that their is a possible fix to the steering loss but my dealer has no clues at this time. Mileage on my vehicle is approximately 14500 miles. I currently have no confidence in this vehicle and will not have my 75 year wife drive it. My age is 77. Another serious incident that I had with this vehicle when it was new was the automatic forward collision braking . I was making a left turn and for no reason the car suddenly braked hard and stalled. I was fortunate that the oncoming traffic stopped and gave me a chance to restart and move away from the intersection. The problem was resolved by my dealer by reducing the sensitivity of the forward collision braking.

Odometer Fraud. The contact purchased a 2020 Cadillac XT5. The contact discovered that there was a mileage discrepancy after the purchase. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 30,475. It was later discovered, upon checking with a local AutoZone, that the mileage was 49,579.

Auto shut down completely in the middle of the road. No one including tow truck driver could not put vehicle into neutral. Once the vehicle was towed to the dealership in was confirmed that battery just died and the dealership stated due to the electrical shifter there was no way to engage neutral since the vehicle could not start. This situation caused major traffic issues for 3 hours as vehicle was locked in position. I would think there should be some way to push the vehicle to the curb allowing traffic to flow. Being stuck in the middle of traffic and unable to push vehicle to the side of the road is very dangerous. Please advise Cadillac that people must have a way to get there vehicle out of the middle of the road and this a very dangerous situation.

While driving at low speed lost all power steering . Was able to get it back home . When checked again later power steering was working . While driving later that day brakes engaged to a sudden slamming stop , red abs engaged light flashed then went away . Both incidents could’ve caused accidents. I’m scared to drive this car anymore. A week prior I thought the gears weren’t engaging / transmission seemed to be slipping ? 6 months prior braking engaged on freeway , also scary .. dealer said it needed a update and would be fine . 5 months ago I was unable to reverse out of my driveway , dealer also said it was in need of a update . I never received notice I was in need of any updates before these problems occurred .

DRIVING THE CAR NORMALLY AT NIGHT THE DASHBOARD LIGHTS WENT TO FULL INTENSITY WITHOUT DRIVER INPUT, AND WOULDN'T CHANGE. A FEW MINUTES LATER THE REAR WINDSHIELD WIPER STARTED OPERATING AND WOULDN'T STOP. TWENTY MINUTES LATER THE CAR FLASHED A NOTIFICATION THAT POWER STEERING ASSIST WAS NOT FUNCTIONING, AND IT BECAME VERY DIFFICULT TO STEER. THE TURN SIGNALS WOULD NOT OPERATE. THE LOW FUEL WARNING INDICATOR CAME ON SHOWED ZERO MILES LEFT EVEN THOUGH THERE WAS AT LEAST A QUARTER TANK LEFT. THE SPEEDOMETER READOUT CHANGED TO ZERO, WHILE WE WERE DRIVING AT ABOUT 35 MPH. WE WERE ABLE TO SAFELY STOP THE CAR AT A CONVENIENCE STORE / GAS STATION. THE IGNITION SWITCH WOULDN'T TURN OFF THE ENGINE, THE HEAT CAME ON AND WOULDN'T TURN OFF, THE WINDOWS WOULDN'T ROLL DOWN, AND THE DOORS LOCKED THEMSELVES. THE REAR WINDSHIELD WASHER CONTINUALLY PUMPED OUT FLUID. THE FRONT WINDSHIELD WIPERS STARTED AND WOULDN'T TURN OFF. WE CALLED HERTZ AND WHILE WE WERE ON THE PHONE WITH THEM THE ENGINE DID SHUT DOWN. HERTZ SENT A TOW TRUCK TO RETRIEVE THE CAR. WHEN HE ARRIVED HE CALLED ME TO ASK WHAT THE PROBLEM WAS WITH THE CAR, AS HE FOUND IT TO BE OPERATING NORMALLY.

VEHICLE STALLS WITHOUT WARNING. ENGINE STOPS RUNNING. AFTER A SHORT TIME, IT CAN BE STARTED AFTER SEVERAL TRIES. THIS HAS HAPPENED WHILE DRIVING ON A MAJOR CITY STREET, THERE IS A RECALL PENDING FOR REPLACEMNT OF FUEL PUMP MODULE. IN THE MEANTIME IT IS AT DEALER (3 WEEKS) AND THEY HAVEN'T DONE ANYTHING TO FIX SINCE IT DOESN'T STALL IN THEIR TEST DRIVES. IT ONLY STALLED A FEW TIMES IN UNDER 2000 MILES. BUT DEALER DOESN;T WANT TO FIX IF HE'S UNSURE IF THERE IS ANYTHING TO FIX.
