1. car stalls/hesitates on right turn. Dealer service could not replicate. Problem started at ownership, and continues at 25K miles. Problem not corrected. 2. check engine light: Car vibrates/shakes standing at idle. 21 days out of service. 3 dealers; four visits. One dealer could not extinguish check engine light. Dealer disassembled engine and made repairs. (exhaust is noticeably louder (not repaired) and the fm radio will not work when the rear defroster is switched on--I suspect a ground wire was broken during the repair (not repaired).

I have a Cadillac 2008 Cts with 24,000 miles on it. The check engine light came on and I took it to my local Cadillac dealer. They stated they could not fix the problem and I had to take it to the selling dealer, don massey Cadillac. Problem: The check engine light came on and I immediately took the car in. My local dealer, allen Cadillac in monroe Michigan stated there were two problems. The timing chain was stretched according to then and the cam and crank shaft were defective. The car is currently in service. I was told by the service tech that this is a common problem with the 2008 Cadillac Cts and that dealer had seen over a dozen cars with the same problem. GM has not issued a recall. When I took the car to don massey Cadillac (selling dealer), there were six other Cts cars in for service at the same time as mine. Although GM is supposed to fix this under warranty, why have they not issues a recall? this is an over $50,000 car with 24,000 miles on it and it will have to have the engine rebuilt. This is the second major repair to this car. This past December, a clip that holds the wiring harness in place snalled and the wiring harness got wound up around the fan and was torn to shreds and had to be replaced. With this many major problem on a car with 24,000 miles (I put on all 24,000 of those miles), what is in store for be when the car has 34,000, 44,000 and beyond miles on it?

My 2008 Cadillac Cts V6 di AWD has a dangerous acceleration lag when you step on the gas to pass or get out of the way of a hazard in road. There is about a 1-2 sec lag between stepping on pedal and rpms moving, and about another second or so before any pick up happens. Doesn't sound like much, but no other car I have had, did this. At the speed of oncoming vehicles, a 1-2 second lag can mean a 30 - 60 yards of distance being traveled by an oncoming car or truck. That sight fills up rear view mirror fast. In my opinion, this is a serious design flaw and potentially death causing defect. This happens anytime I need quick acceleration, and is also happening in other cars I tried at dealership to see if it was just mine.
