Hi! Welcome to JustAnswer. I'm Ron Z and I'll be helping you with your question today.

Unfortunately, the 2006 CTS with the 3.6L engine was in fact affected by the timing chain issue. This is an extremely well-known issue. GM has issued a technical service bulletin that states the problem can be loose timing chains or tensioners or the reluctor for the crankshaft sensor pressed on the crankshaft may have moved. When this is the case, the Check Engine Light will be set with two or more of the following DTCs: P0016, P0017, P0018, P0019, P0008 or P0009. Unfortunately, this is a major repair. Might be a good idea to stay away from this vehicle. Please remember to leave a rating using the 'stars' or click 'Accept'. A 5-star rating is much appreciated!
