I brought my car to the dealer last week so I thought I would give an update on the ticking noise. A while ago I’ve noticed a loud clacking noise coming from the passenger side rear of the supercharger. This sound is heard best during the first 10-15 minutes of a cold start. The noise is so loud that you can hear it while sitting inside the car. Even after driving around, you can hear a faint tick. I can’t imagine that this is normal. Anyways, I was told by the dealer that this clacking noise is normal. I called GM and explained that I’ve been around other ZL1s that do not make this noise. They opened up a case and will be checking into the problem in a few days. What are your thoughts? Suggestions?
