2017 Cadillac XT5 Complaints

While driving down the freeway at approx. 65 miles per hour, I heard a very loud sound like an explosion, or a huge balloon exploding, and then heard crackling of glass. It was very scary and dangerous. I had to slow down immediately, and was able to get off the freeway. I pulled into a gas station, and tried to figure out where it came from. I realized that my sunroof was either hit with something or just simply exploded. There was a hole in the center, and the glass was cracked throughout the front sunroof. I could hear the glass pieces moving around on the sunroof shade that was thankfully closed. I bought duct tape and covered the hole and all of the cracks so I could drive it home. I took side streets and drove slowly home.

I purchased this used car in the end of July 2025. Within the last month the service transmission light came on. Within a 24-hour period, the message changed to, "service transmission unable to shift Soon". Also alarm bells go off when I first start the car and sometimes during driving. The car feels like it drives correctly and smoothly with no shifting issues. Sometimes when that second message and check engine light icon being comes on, there seems to be a third message that is trying to pop up behind it but it does not. It seems like there is a glitch in the system. This was very concerning and scary for me. My research shows me that this has been a chronic problem for my make and model and year of car. I've also heard it can be even time to check and or change the transmission fluid. That needs to be a different message all together without causing alarm that the transmission itself is not functioning properly. I have not driven this for 10 days because many repair shops in dealer...

I have a 2017 Cadillac xt5 which the transmission is kicking and has a shattering issue car was just over the warranty and was told I have to pay for a replacement car had 70k miles and was told from a mechanic that there was a recall on these cars when I checked my vin the car is not under recall but is presenting the same issue as the ones under recall.. I took it to amoco replace fluid and car still has issue. Iam trying to see my options on how to go about it..

9/17/25 I purchased 2017 Cadillac Xt5 platinum from a dealership. It came with a dash mat which was concealing cosmetic damage to vinyl around air bag on passenger side, and was unglued throughout entire dashboard. I didn't have a vehicle inspection before buying car, nothing reported on Carfax. And I asked dealership why they used Velcro and dashmat to conceal damage. No response.

Catalytic Converter on my 2017 XT5 had weld crack Oct 2025. Causing loud noise and exhaust to enter cabin of vehicle. This was the second convertor to do this. In 2023 I had to have the other catalytic convertor on this same vehicle changed out by the Sewell Cadillac dealership for the same problem. That time I only had 50,000 miles on the car so the dealership did it for free (after I found that they had to cover up to 80,000 and they acted like they didn't know that and had quoted me $2000). This time in 2025 I had 80,805 miles so I had to pay $1010 to have it replaced by an outside repair shop. The technician says since we had to have them both replaced and the car is only 8 years old, it is probably a design flaw. He told me to report it. I see another complaint for the same thing and I see they did a recall on some from California vehicles for something with the catalytic convertor and a recall on some in 2022 and 2023 vehicles for an issue with the catalytic convertor. I expected...
