Cadillac XT6 – VIN: [XXX] echanical Failures, Ignored Transmission Recall(s), and Dealer Negligence I write this letter to formally place General Motors Company on notice of a pattern of serious mechanical failures, ignored safety recalls, and dealership indifference involving my Cadillac XT6, referenced above. This vehicle has been presented to Sam Leman Cadillac of Champaign on multiple occasions for mechanical issues, including—but not limited to—cooling system failures, thermostat defects, persistent check-engine warnings, and abnormal vehicle operation. Service records confirm repeated interventions, temporary fixes, and diagnostic acknowledgments without meaningful long-term resolution. More alarming, however, is the dealership’s failure to appropriately address and disclose known transmission recalls and other safety recalls applicable to this vehicle.

The vehicle was previously recalled for an intermittent backup camera failure. Prior to me purchasing the vehicle, the recall was completed and documented as repaired. I went in to the Myrtle Beach Cadillac dealership for reoccurring issues with the camera failing exactly as disclosed in the recall. It will randomly cut to a black screen with a camera icon crossed out in red. It is a true safety issue that leaves my family as risk of a collision or injuring someone else.It cannot be recreated on request as it is happening intermittently. The dealership refused to inspect the safety recall repair for proper operation and only stated that the recall repair was completed.
[XXX] My 2021 XT6 occasionally stumbles when accelerating from a stop, both when the engine is running or when it has auto stopped, only occasionally. If the car won't accelerate properly, it can cause a collision, especially if making a left hand turn at an intersection. It started happening about June 2025 and kept reoccurring more frequently as time passed. It was brought to a dealer early August, they said that it might be a bad battery, I installed a new battery on August 19, 2025, it was ok until late November 2025, then it started happening again. Yes, it can be inspected upon request. There were no warning lamps or messages, symptoms or problems prior to the failure. This has been happening about 6 months now.

1)The display on dash reads upon start up, “Steering Assist Reduced”. 2)There is no Engine temperature readout displayed on cluster. 3)When the vehicle is turned off, the coolant fan stays running for a few minutes at full speed. All of these issues are correlated. Also, many XT5’s & XT6’s have had this issue in the past.

Car started and ran at idle for 5 minutes. 10 minutes later when attempting to restart, the engine churned for several seconds then ran for about 2 seconds and cut out. "Press to Start" button remained showing green and would not respond to being pressed. The car was stationary in my garage; this would have been extremely dangerous if it happened on the highway. It seems to be a complete failure of the fuel system on a 2021 model with under 27,000 miles

The vehicle's check engine light came on late afternoon and then started with a delayed turn over, but not actually starting thr following day. The vehicle had to be towed to the dealership. The technician and service advisor commented immediately that it is likely the fuel pump control module. With the commentary about the likely cause was that this is a widespread issue among GM vehicles. Thankfully, the vehicle was at home when it stopped starting but the transition from check engine to stopping operation was almost immediate.

In April 2023 I was backing out of a parking space when a message displayed on the dash that “The Parking Assist Have Been Blocked, See Owner’s Manual “. In this event there were pedestrians walking behind my vehicle and if not for my cautions always while backing could have caused an accident. This has since been intermittently happening and I have taken it in to the dealer 2 times without repair.
The problem is the fuel pump control module is faulty and broke twice now. The car was purchased in 2021, new. Within months the fuel pump control module failed while I was driving in traffic, in an elementary school zone with children all around. I tried to drive through an intersection when without warning the car abruptly stopped causing the cars behind me to swerve to avoid a collision. Good samaritans had to push it far out of the way due to the children crossing. I was told by Sawgrass Cadillac that it was the fuel pump control module that has a short starving the car for fuel without warning because it is an electrical issue. It was fixed, until July 4, 2023 when again while in traffic the engine light came on, the car shuddered and then abruptly stopped. Cars around me swerved, nearly colliding into me with my daughter in the car. Sawgrass Cadillac again said it is the fuel pump control module that they are looking to replace it again. This is a design failure, one that
I was driving about 25mph all of the sudden the car automatic applied the brakes.
