2010 Chevrolet Cobalt XFE 4dr Sedan (2.2L 4cyl 5M)
We have an 09 XFE with the 2.2 Ecotec. The engine rattles loudly at start up for about three seconds then quiets down nicely. This car only has about 2400 miles on it. Anyone else having this type of problem? I'm a little shy of this engine because of the noise.
