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.
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.
