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…”

“This vehicles transmission has went out twice. Both while driving and could have caused death on the freeway because the vehicle came to a complete stop. 2 young children could be at high risk for this issue. It was taken to the dealership the first time and the transmission was replaced and within 3 months the same issue occurred which could have been deadly. It again was given a new transmission and 6 months later the same issue is occurring. Yesterday the check engine light came on. The vehicle began to drive very slow as I was on the main road. Another collision could have occurred but thankfully I was able to turn into a parking lot and stop the vehicle. GM corporate has Been contacted multiple times and have stopped answering all my calls and conerns. This issue can cause major damage to my family as well as others. A new vehicle like this should not have these issues”

“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. When the malfunction occurs, the vehicle displays a warning stating "Left Rear Turn Indicator Failure," accompanied by rapid flashing of the turn signal indicator. 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 intention to turn or change lanes, creating a potential collision hazard. There is also a significant secondary safety concern involving the vehicle's Driver Information Center (DIC). When the "Left Rear Turn Indicator Failure" warning appears, an unusually large notification occupies most of the central instrument display, obscuring the digital vehicle speed readout and other driver information normally displayed in that area. This creates an additional safety concern because…”
