UNKNOWN OR OTHER
The thermostat sensor is defaulty. While driving all of the dashboard component lights flash on and off and the vehicle loses power while driving. Called the dealership and the technician knew exactly what it was because he said this is a known issue and when I got the vehicle to the dealership they didn't need to do a diagnostic, they knew exactly what it was. A recall should have happened to avoid this.

POWER TRAIN
Transmission suddered. Took to the dealer and they said that there are parts in the transmission that need to be replaced. They recommended not driving the vehicle because there could be complete faliure of the transmission causing the car not to move. They said that parts are on backorder and did not give a timeline of when the parts would be available. They said they did not have a vehicle to drive while we wait.

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.

UNKNOWN OR OTHER
When backing out of garage, but still in the garage, the rear- view camera shows a clear image. When the car backs into the sunlight from the garage the screen goes white for 10 seconds before the image reappears. The dealership Maintenance Department said that is normal! If I step on the brake while the image is white, the picture immediately comes back. If I place the transmission in park, it immediately comes back. When I drive the car at night, the rear-view mirror looks like I am looking through dense fog. The dealership Maintenance Department said that was normal because it is an infra red system and when LED headlights shine into it it causes this reaction! This car is still under manufacture warranty. I have owned two other identical XT6 Cadillacs and they did not do this. I have the 4/29/2025 Service Report of the dealership that reported the rear vision camera and back-up camera very foggy at night, but fine during day.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
During a cross- country trip, we had driven more than 300 miles, but the fuel gage indicated full, the Fuel Range Indicator showed a 688-mile range available in the tank which is much more than a 2025 Cadillac XT6 should indicate. The fuel gage indicated full even though it was not. I pulled the car over, shut it off and restarted, but it still erroneously indicated full. The indication remained that way for approximately 1400 miles. During the trip, while the gage still indicated full even though it was not, the tank was hard to fill. The gas station pump would automatically click off as if the tank was full, but it was not. I could only fill the tank by continuously over-riding the automatic shut off. This problem could not be duplicated by the dealership maintenance department on 4/29/2025. I picked the car up on 5/10/2025. I have a copy of the 4/29/2025 Service Report of the dealership.

STEERING, ENGINE
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.

ENGINE, POWER TRAIN
I purchased the new 2022 Cadillac XT6 in June 2022. The first week I owned the vehicle, I was driving and I lost power and the vehicle came to a stop. The mileage on the vehicle was 134 miles. The Cadillac dealer indicated there was a failure in the engine and power train that caused the engine to lock up. The dealer/GM replaced the engine in the new car with 134 miles on the vehicle. Attached is the service report from the Cadillac dealer that replaced the engine

ENGINE, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
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

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
While driving the dashboard screen goes blank including the radio. If using adaptive cruise control it also shuts off. After five or six minutes the cadillac symbol will appear on the radio screen and the dashboard screen will begin to sign back on. You must reset the cruise control. Everything on the dash is black including the speedometer and gages. This has occurred numerous times and the dealer informed me that there is no recall and no solution to the problem. My son has a 2023 Chevrolet Tahoe with the same problem. The first time it happened was on an isolated road at 10:30 PM. I pulled over, not understanding what was occurring. I consider this dangerous not know what’s going on how long if will last
