I've been a loyal DTS/Deville customer for 30+ years. Dealer tried to talk me into a XTS; fortunately, I waited "Patiently" for the CT6. Bought it early June, 8,000 miles ago. Likes: styling, quietness, handling, ride, acceleration, braking, cornering, fit and finish, seating, safety features and entry/exit. Dislikes: a/c continually "Freezes up" when operating continuously 40 min to an hour (blows ambient air). Will reset after 20 min in off position. Dealer attempting to resolve. Instrument panel air vents won't allow air flow above the panel (directed too low). Auto shifting not smooth (compared to '10 DTS). Overall, best car I've owned, so far. Highly recommend to friends. ………. 2 YEARS AND 48,000 MILES LATER: A/C still freezes up, 90 degrees outside temp and high humidity, 5 trips to dealer, "repaired" again last month, can't test. Will not use for several cold weather months. Transmission vibrates, acceleration and cruise. Back to dealer tomorrow. Still like styling, ride, handling, braking, fit/finish and safety features. Depreciation / resale value disappoints me. No longer "HAPPY CAMPER" …….. 3.5 YEARS AND 66,000 MILES LATER: A/C problem seems to be resolved after7 visits to dealer. Cadillac tech rep got involved. Experiencing transmission vibration issues. May be resolved after 2 dealer visits. Still like the many positive features of the vehicle. Very low trade in value disappoints me. .......... I've owned this vehicle for 4.5 years and still enjoy driving it; 89,000 miles and no maint. problems in past 2 years. My last problem was with the transmission. Dealer repaired and GM extended warranty. I'll look for a '19 or '20 CT6 next spring.
