I noticed steering issues with my 2007 LS Cobalt. The dealership replaced it at no cost to me since there was a recall. It has made a huge difference in the feeling of control when I'm driving. I don't drive much so I wasn't sure if I was just imagining this lack of control or not but I feel a lot safer now.
Acceleration. This car has great style for the price and I love the candy apple red color. The car doesn't look like a box. It has a classy stylish look.
Perhaps a little better quality interior components, some of the plastic items.
