About a month ago I purchased a 2018 CT6 platinum with Super cruise from Moler in Iowa. I bought the car out of state and was assured before I left to drive home that the super cruise was working fine. I tried the super cruise on the way back to Ohio and found it did not work. It has been down in Fort Wayne, IN at a dealership for 3 or 4 weeks on and off. They have reprogrammed and changed components. Still doesn't work. It looks as though they are going to tell me that they can"t make the repair. I wonder why GM hasn't sent down an engineering type to find the problem. I'm wondering how many other ct6's have this issue. Wont work, can't be repaired. I hope this doesn't become a legal issue. Oh well. Anyone have any ideas? Please, let me know. I'm about lost now.
