Consumer Reviews for the Cadillac CT6
Read recent reviews for the Cadillac CT6
Terrible Service
Robert J. Tarte, 08/29/2018
2016 Cadillac CT6 Premium Luxury 4dr Sedan AWD (3.6L 6cyl 8A)
The electronics are terrible and Cadillac and GM customer service is terrible. My vehicle,e has been at the dealer for 3 weeks. 2 parts have been replaced and the vehicle now cannot be programmed. It took 12 days for a part to be shipped despite my request for overnight shipping. Cadillac told me that they have their processes. GM told me that they have their protocol. Thus, 12 … days to ship a defective part. My dealer told me that they are attempting to get authorization for a new vehicle but GM. wants to send. Yet another part. There is a question whether the part is even available,but GM protocol is the most important thing to GM,not a satisfied customer. After 7 Cadillacs, there will not be a number 8. It is a shame, because the CT 6 is a beautiful car. GM has not changed since the bankruptcy and probably never will. Do not buy a Cadillac.On Sept.4 after 27 days, vehicle finally fixed. Hopefully, GM will offer some compensation for my inconvenience and time spent attempting to resolve the matter.
