Affected Component: Exterior Lighting - Left Rear LED Taillight / Turn Signal Assembly DESCRIPTION OF SAFETY CONCERN My 2020 Cadillac XT5 has developed an intermittent malfunction involving the left rear LED taillight and turn signal assembly.

The malfunction occurs unpredictably. A visual inspection of the taillight assembly reveals no obvious damage or failed LEDs. My primary concern is vehicle safety. An intermittent malfunction of a rear turn signal may prevent motorists behind me from receiving a reliable indication of my…

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…

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…

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…
