Although I loved the car overall at the time I decided to own, , my dream car Cadillac Cts has turned into my dream nightmare. Cadillac Cts 3. 6 2008 when I get on it a little bit acceleration it makes a sound that sounds like all air leaks inside the car. The dealer was reported ever since my first early visit to service center but it's only during my last visit to the dealer they mentioned gm has sanctioned approval ie. At the time the odometer reads 65000km? strange! the door locks are terrible?despite rectifying; time and again by your dealer the problem still persist to date. Safety hazard indeed. The computer had error as for tyre low air pressure very bad on safety standards. On 12th Aug 2012 while I was en-route to the Cadillac service center the vehicle had a break down. On the display screen near odometer it displayed engine temperature too high ?. Due to this I had to pull the car towards safety and got stranded in the middle of the road under the hot sun. How can you justify a car which is regularly maintained by your authorized agency at regular periodic intervals to have such a fate? I felt it was good to have it serviced during my absence in town before the regular km interval; but, only to get stranded on the road in the hot sun. It is indeed, too much to suffer after buying a car of gm flagship brand < Cadillac > and suffer agony on the road side. Not to mention the dealerships warranty you provide with the purchase of the new car from your authorized agents, probably don't fix anything with the warranty service program. If the job was right then the engine should not have over heated especially when the car is just run 71000 kms. Approx. . .
