“The car shows a warning engine power is reduced this is the second time in 3 months. The car revs at 5000rpm and only goes 15 MPH, very dangerous. The dealer replaced a sensor last time and seems unconcerned for the safety of driving.”
NHTSA complaint #11405665, filed 2021-03, 25,991 miles“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. …”
NHTSA complaint #11750727, filed 2026-07“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. …”
