I purchased the 2017 Cadillac CTS off the showroom used with just under 9000 miles. I didn't test drive it, considering that I had been test driving the same year and model for 2 weeks and it was in the center of the showroom floor. What could be wrong with it at that low mileage, right?

Well, I signed off on all papers and drove it home to find out that the transmission was shuddering and shifting weird. I went the next day (a holiday weekend) and mentioned it to them. They said since it was Sunday, service wasn't open, and to call Monday. The service guy came and picked it up, and gave me a loaner. I've read several issues on this transmission problem the day after buying it and have told the dealer to put me in something else without an 8 speed transmission, since it's a GM transmission issue affecting several different models with the same transmission.

The sales manager said he would need to talk to his GM. Since then, the service department called and they offered to change and flush the transmission fluid. I said that doesn't sound like that fixes the transmission for me to be comfortable keeping the car. Since there have been many complaints, and GM isn't rectifying this to their consumers, I don't feel comfortable with the purchase!

I own a 2017 Cadillac CTS with 45,000 km. It has the 8 speed transmission. As long as I have owned this car the transmission has been wonky. I have taken it in to the dealer 3 times to have the transmission serviced, which I feel needs to be replaced, and each time it came back with a clean bill of health. They have replaced the converter and the valve body which made no difference. They also did a software upgrade and a flush which made little difference. Being a Cadillac I have certain expectations from this car which are not being met. I owned a 2007 CTS prior to this and it was trouble free which is why I purchased another Caddy. In my opinion this transmission is nothing more than a boat anchor and is seriously altering my opinion of Cadillacs. Has anyone else experienced the same issues as me with a similar Caddy? Was there a solution offered? It is my understanding a class action lawsuit is being prepared in the U.S. for this same problem.
