Engine · reported Oct 20, 2026
I noticed a water sloshing sound behind the dash when first starting out for about a month. I didn’t get any warning lights or notice anything leaking under the car but when I checked under the hood the coolant reservoir was empty. I made appointment at GM dealership and they found I had a leak along the side seam of my radiator. The car only has 61k miles! I found online that GM has noted a structural design issue in my XT6. The radiators were engineered with tight thermal break tabs. If they stay locked in place they trap immense physical stress during engine heat cycles and force leaks…
Electrical System · reported Oct 11, 2026
On September 15,2026, my vehicle experienced a catastrophic los of power steering assist accompanied by severe heavy steering. Please review General Motors TSB 20-NA-215 & TSB 17-NA-158 both addressing this issue. My 2021 vehicle has a build date of September 19, 2020 which falls "directly" in the time frame covered by these bulletins. Essentially, General Motors KNEW of the problem! The only warning I got was a two second message flashing across the instrument panel stating "Power assist reduced, drive with caution" ... followed by "Service Power steering" Then severe loss of steering!!…
Fuel/Propulsion System · reported Jul 1, 2026
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.
Back Over Prevention · at 33,000 miles · reported Mar 12, 2026
The contact owns a 2021 Cadillac XT6. The contact stated that while reversing, the rear-view camera intermittently displayed a blank image. The vehicle was taken to the dealer, who was unable to duplicate the failure and informed the contact that the contact had to pay for the rear-view camera software update. The vehicle was not repaired. The dealer informed the contact that the vehicle was previously repaired under NHTSA Campaign Number: 22V709000 (Back Over Prevention). The manufacturer was made aware of the failure. The failure mileage was approximately 33,000.
Power Train · reported Feb 9, 2026
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.
