2020 Cadillac XT5

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 radiator had a leak that required replacement in my 2020 Cadillac XT5. The car only had 30,000 miles. Because of that GM replaced the radiator for $600 instead of the standard cost of $2,000. This is the 3rd Cadillac of my relatives of similar age that had a radiator leak. The service manager admitted they are replacing at least 7 of these every week. In my opinion this is a manufacturing defect and should be replaced at no cost instead of a negotiated lower price. My concern is that GM is repairing these vehicles with the same parts that have failed so many times. It will likely happen again in less that 5 years. A second issue is the transmission was shuddering during acceleration. GM replaced the torque converter under warranty. But I have read this is also a common problem with GM cars for several years. I think GM should have to come up with a solution and contact owners for a recall.

The contact owns a 2020 Cadillac XT5. The contact stated that while in drive and attempting to shift into reverse (R), the gear shifter knob fractured. The gear shifter shifted into park(P) and failed to respond as needed. The contact held the fractured piece in place to move the gear shifter. The message "Gear Conditions not Met" was displayed. The vehicle was taken to a dealer, where DTC: P07B4, P07BA, P17A4, P17A8 were retrieved. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 109,756.

The contact’s father owns a 2020 Cadillac XT5. The contact stated that while attempting to use the driver's side rear seat belt, the seat belt failed to buckle securely. The contact had not attempted to use the rear passenger’s side seat belt. The contact stated that the vehicle had not been taken to a dealer or independent mechanic to be diagnosed or repaired. The failure mileage was unknown.

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.

When driving on the interstate traveling roughly 70 miles an hour went to accelerate and vehicle transmission made a hard shift and clunk. Then RPMs all transmission started slipping attempted to use paddle shifter to change gear felt transmission engage a different gear than instantly disengage felt like vehicle was in neutral Vehicle would not even allow me to drive at any speed had to coast with flashers on until I was able to find a safe area to pull onto the shoulder. Was told by the dealer, lots of metal found in the transmission. Transmission codes were. P0700, p0796, p2732, p18ab, p18ad , p187d vehicle was making whining sound like a cracked valve body inside the transmission. Requested failure analysis from GM Cadillac, and still have not received results was told by the dealer it was like the transmission was worn out. There was a lot of clutch material. No warning, signs or symptoms of the failure. Have had the vehicle back for three weeks and the new transmission is shuttering, feels like it’s slipping slightly sometimes and having issues already still waiting on an opening to bring the vehicle back to dealership again. The nine speed transmission is having issues like the rest of GM’s transmissions and the only one that has not received a huge recall like the rest. Cadillac rep stated when that issue occurs under 3000 miles they typically replace the transmission. No transmission will receive failure analysis if it is replaced like I think. Had appointment at Cadillac. Dealership today scheduled supposed to drop vehicle off and receive a loaner vehicle when I arrived found out they did not have a loaner vehicle told them I felt like it was not safe to drive with the transmission acting up and notified Cadillac rep I felt it was not safe to drive Cadillac wrap was not helpful. And did not offer any real assistance. Had to bring Car back twice already due to exhaust leak after transmission was replaced. Cadillac rep. Never responds to any email sent
