2021 CADILLAC XT6 Electrical System Problems

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. Despite GM’s documented awareness of widespread transmission issues affecting similarly situated vehicles, the dealership elected to either minimize, ignore, or defer corrective action—placing convenience and cost avoidance above consumer safety. This conduct raises serious concerns, including: •Failure...

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.

RECALL FOR CABLE FOR VISION SYSTEM REPAIRED 5/28/2025. ON 6/29/25 SAME ISSUES OCCURED. TOOK TO DEALER 7/18/25. DEALER CONFIRMED CABLE REPLACED. ATTEMPTED TO REPROGRAM VIDEO PROCESSING CENTER SEVERAL TIMES ( I WAS AT DEALER 7 HOURS). DEALER INDICATED THAT THE VIDEO PROCESSING CONTROL MODULE IS NOT ACCEPTING RE-PROGRAMMING. INDCATED THAT PART MUST BE REPLACED AT A COST OF $973.00. SYMBOLS APPEARED ON DASHBOARD SCREEN : TRIANGLE WITH EXCAMATION POINT, AND BOX WITH "X" THRU A CAMERA. CAR IS DIFFICULT TO SEE OUT OF WHEN BACKING DUE TO PILLAR PLACEMENT IN REAR. RELY ON CAMERA(S) ON 4 SIDES OF CAR TO SEE WHAT IS GOING ON. I SEE THAT SEVERAL OTHER GM MODELS HAVE HAD THIS PROBLEM.

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
