Customer Question

2009 Pontiac G6 GT that upon cold start, I get sharp rattle noise up front for 1-1.5 seconds. It doesn't happen after it's been started and ran within a few hour ago. Just on cold starts. It's a rather loud rattle.

There is a tsb out on "Sharp Engine Rattle Noise At Start Up May Also Set P0011 P0014 P0016 P0017". So, to begin, do you have a scan tool or code reader?

It says to suspect the drive belt but if the belt is ok and you could tell simply by removing the belt and listen if the noise goes away, then if the noise is still present and is very short and sharp in duration (2-5 seconds). This may be an issue with the cam actuators not parking properly.
