Cold Start Knock on 2009 LAP Cobalt 2.2
I searched the forum and another cobalt forum and came up with nothing on this topic. My 2009 cobalt ls 2.2 LAP has been having a cold start knock on startup. It has been happening every day. The temperatures have been around the 30s-40s. If anyone has had a 99-02 silverado/suburban with the vortec motor, it sounds exactly like that cold start knock. I thought this issues would have been fixed. It seems like everyone on here has no cold start issues. Im having a cold start knock that is a middle to loud volume knock. The oil level is at full on dipstick. Car has 8600 miles on it. I changed oil at 8500 to synthetic because i have been having this issue since 8000 miles on cold start up. Issue is still there. I searched google as well and had no assistance to this issue. I dont want to take it to the dealer yet and get the its normal for the car speech if it really isnt. Is this a new VVT design issue or is it perfectly normal with the short skirt pistons still? Any insight to this issue would be appreciated. Thanks.

I personally know the service manager and they know we do the oil changes and I keep records. I just think having a cold start knock is crazy on a brand new car with this low of miles.
