The car only has 35000 miles on it. The engine misfires constantly when giving gas especially if your going up hill and there is more load on the vehicle. After I had $5000 worth of work to fix the problem at a Cadillac dealership. They couldn't fix the issue so they came back and said that we needed a new engine. We told them over and over again that we don't think it's the engine but they guaranteed us the new engine would fix the problem. So another $5000 later and still not fixed. The vehicle idles fine, it only happens while driving. The check engine light eventually comes on indicating misfires in 2 cylinders.
Check engine light on. Failed emission testing. Diagnostic testing indicate a trouble code 2008 and recommends replacing timing chains. 74,000 miles.
Car has failed emission testing for 2 consecutive years since I purchased it. After driving for the better part of a year I took it to a dealer in 2018 and explained that check engine light comes on and off persistently. They tested emissions and said it passed. Again in 2019 it failed emissions again and the dealer provided a diagnostic test which indicated that time chains needed to be replaced. Estimate for repair $3900. 00. In short problems have existed for approximately 3 years. This complaint is correct from previous filing number:11174923.
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?.
