The service center told me that every cruze will have this sound.. even the demo car... its just the sound of the hydraulic pump to fill up the upper level of the engine with lubricant during warm-up. This noise is just for a few seconds. But i wana know is it all the cruzes gives this kind of sound?
No i have mine do the same. I notice that the colder the car the longer thw rattle goes. The guy is right, its to warm the car up. Youll know when its warmed up cuz the car starts loud, then goes quiet after a bit. I notice mine chills after 30secs. In winter about 2min-ish
I started a '12 2LT on the dealer's lot today and it didn't rattle or make any odd noises. The radio was off as was the vent fan.
Had a second thought on this. The Cruze has a variable speed oil pump and pumps harder with higher rpms. If the rattling were the oil pump, the rattling should change in concert with the engine speed. Does it?
