Service engine light came on at 93203 miles. Obd code P0008 timing chain problem. There's a special coverage adjustment (sca) #11340C on 2007-2009 Cadillac Cts vehicles for that known problem. I'm at the Cadillac dealer and my specific VIN doesn't fall under that sca. I called the Cadillac hq and they opened a case #71-1492554265 and told me to file a complaint with the NHTSA. The sca is 10yrs or 120K miles. It's a known problem which needs to be addressed. Thank you

The check engine light illuminated and dealer diagnosed problem code as P0008 pertaining to the timing chain. I was then told that the timing chain was stretched and needed to be replaced for a cost of approximately $2200. Vehicle is well-cared for and has 83,800 miles on it. According to other complaints made to NHTSA, a number of people have experienced premature timing chain wear with this make/model. I called GM to inquire about a special coverage adjustment bulletin, issued 11/5/12, #11340C, pertaining to 2009 Cadillac Cts and other vehicles with premature timing chain wear. Even though my vehicle is experiencing this exact issue and presumably would be included in the special coverage adjustment (which extended the warranty for affected vehicles to 10 years/120,000 miles for this issue and requires dealers to replace the chain without the customer paying for it), GM told me that my vehicle was not eligible as only "some" vehicles were included and apparently my VIN# was not one of them. If my vehicle is experiencing the exact issue that necessitated the special coverage adjustment, then why am I not given the benefit of the coverage" instead, I am forced to pay out of pocket for a known premature wear issue? why doesn't the special coverage adjustment apply to all 2009 Cadillac Cts vehicles, not merely "some""

While driving I heard a loud noise from under the hood and the service engine soon light came on. Once able to stop I called onstar and asked them to give me a diagnostic. I was told that it was an engine error and to take in for service. I took the car to the dealer first thing the next morning. Was told my timing chain needed to be replaced. My car has less than 28,000 miles. Called GM/Cadillac was told that while there was a recall (#10287) for prematuring timing chain wear for certain 2009 Cts mine was not one of them.

Premature timing chain wear. Needs to be replaced for approximately $3000. Check engine light alerted us of the situation. From our research, there is a known issue with this particular GM vehicle. GM denies there is an issue for our VIN. Timing chains do not to wear in 5 years 66617 miles. It is a manufacturer defect.

The check engine light came on. I took it into Cadillac and they said the timing chains needed to be replaced. General Motors announced a customer satisfaction program 10287 in Feb., 2010 for premature timing chain wear on 2007-2009 Cadillac Cts. There is obviously a problem with the timing chain wear but I was told that mine wasn't part of that. Very early for that to happen with only 70,000 miles on the car. I was told the cost to repair would be $2650.

2009 Cadillac Cts. Consumer writes in regards to vehicle vibration/unexpected loss of power and transmission shifting and acceleration problems. The consumer stated the vehicle began shifting gears erratically, vibrating and lacked power. The condition appeared irregular and for some time, no trouble light appeared. Once a light finally appeared, the vehicle was taken to a Cadillac dealer who determined that all the ignition coils on one side of the engine were defective. The service representative explained that when one or more ignition coils fail, the engine would have a greater vibration and lack of power. In addition, the coil failure would cause the transmission to unexpectedly downshift to compensate for the loss of power and with multiple coil failures it may shift multiple times each time more power was needed to maintain the throttle speed. In July 2013, the consumer began experiencing the same performance issues. Again, no trouble light appeared. A trip to the dealer resulted in nothing being found, despite the service history of the vehicle. The condition continued and in August 2013. The trouble light appeared. The dealer found an ignition coil on the other side of the engine was defective.

GM 3.6L timing chain stretch without warning. Had it failed at speed, it could have been a dangerous situation.
