I took my SUV to Heritage Cadillac in Lombard, IL for a revving sound while accelerating, specifically from 0-35mph and then acceleration on the highway at higher speeds. It sounded like I was revving the engine even when I wasn't accelerating and stay at a constant speed. There were not any service lights or notification of any issues in my vehicle. The car is at 59,000 miles, I paid $230 for a diagnostic run only to be told it was a "Faulty Muffler" and needed replacement for $1479.66 as it was not covered in my extended warranty. When I took it for a competing bid at a national-brand muffler shop, I was told parts were very hard to get for it as the car was "so new" and that he had another customer bring in for the same problem, but he couldn't find the muffler in his national data base. This lead me to research further why this would happen to a car only 5 year in. This led me down a rabbit hole researching this issue on other Cadillac forums. I'm seeing a recurring pattern among 2020-2021 XT5 owners with the 3.6L engine: a whiny noise when accelerating at low speeds, peaking around 3,000 RPM, traced to loose baffles inside the muffler or a restriction in the exhaust system. Several owners report first noticing it as early as 2,000 miles, with it getting louder over time - which lines up closely with what I experienced. More notably, multiple owners with this exact symptom got their full exhaust systems replaced under warranty, including vehicles with comparable or higher mileage than mine. I've also confirmed there are no open NHTSA recalls on my vehicle, so I know this isn't a recall issue. But given how consistently this specific failure shows up across other XT5s of the same model year and engine, it looks less like isolated wear and more like a known defect pattern.

I am reporting an imminent, life-threatening safety defect regarding a Cadillac XT5, purchased 1/10/26 and repurchased by the dealership on 5/16/2026. While driving, this vehicle experiences an unpredictable and intermittent defect causing the transmission to unexpectedly shift into PARK while the vehicle is in motion.The vehicle was taken to the franchised Cadillac dealer it was purchased fr three times for repair assessments. The service appointents lasted between 1 week- 4 weeks. In total, the car was in my possssion 5 days since the first service appointment due to the ongoing, dangerous drivetrain defect. On the 2nd attempt, parts of the transmission were replaced and the dealer documented at least one occurrence of the gear shift failure, but the defect was not resolved. General Motors (GM) corporate inspectors subsequently inspected the vehicle. Ater that, the dealership repurchased the vehicle from me to take it off the road. About a week after the dealer repurchased the car, GM contacted me, wanting to repurchase the car. When i told them it was already repurchased by the dealership. GM's reponse was to offer me financial resitution for the payments I made only if I sign a General Release of Liability(GRL) for them. However, the dealer has since listed this vehicle for sale to the general public without any evidence of repairing the defect. It is currently being marketed to unsuspecting consumers. This vehicle poses an immediate crash and injury risk to anyone who drives it or shares the road with it. The CARFAX report does not reflect any of the drivetrain issues,nor does it reflect the buyback. GM's response regarding my concern about the dealership re-selling the car was that its out of their hands since the dealer owns the car. I will not sign the GM Release until the records accurately reflect the safety defect. I filed carfax dispute 6/22/26 in an attempt to protect others from this dangerous vehicle.
