2020 Cadillac XT5 problems

Filed Oct 26, 2026 · Lights · FL

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 the driver cannot readily see the digital speed reading while the warning is displayed. The notification may also distract the driver when it appears unexpectedly during operation. I have included a photograph documenting the warning and its obstruction of the instrument display. The repair is not covered under GM's factory warranty. Additionally, the third-party extended service contract purchased and provided by the selling Cadillac dealership denied coverage, classifying the problem as a bulb-related failure despite the vehicle using an integrated LED lamp assembly. The substantial replacement cost may discourage owners from promptly repairing a malfunction involving an important vehicle safety component.

A recall (the federal safety agency 22V70900)was issued Sep 22 2022 on Cadillac XT5 2020-2021. The rearview camera coaxial cable connectors may have been crimped improperly, causing the rearview camera to fail or function intermittently. This has happen to my vehicle (2020 Cadillac XT5) on several occasions. I took my vehicle to the local dealer and was told that there were no recall on my car. Later I was told that the recall number was closed. GM recall number was N222378380. I did not received a recall letter. What steps should be taken to correct this issue without me absorbing the cost? Thank you.

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 the federal safety agency 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.

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.
