“Your site shows no recalls. I got a recall for a repair I had to have done a few months ago. I just got the recall notice from GM, but when I called to inquire about a reimbursement, they state the recall was released in 10/2025. Even though your site says there was no recall at the time.”Owner report · Fuel/Propulsion System · Mar 2026
“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.”Owner report · Electrical System · Dec 2025

“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.”Owner report · Electrical System · Jun 2025

“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.”Owner report · Steering · Jan 2025
“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”Owner report · Fuel/Propulsion System · Sep 2024
“The contact owns a 2021 Cadillac XT6. The contact stated while in reverse, the back-over prevention camera image failed to display as intended on the screen. No warning light was illuminated.

“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.”Owner report · Fuel/Propulsion System · Dec 2023
