I have owned my Cobalt for about 3 months and my initial impression has been very good. Very little rattles, good mileage, and the 4-cylinder engine has more power than I expected. But the car has been to the dealer twice now for an oil leak from the manual transmission, first at 800 miles and now at 1300 miles. It is in the shop right now and the dealer is replacing the transmission. Safe to say I am not happy. A three-month-old car with 1300 miles and the transmission needs replaced. Hopefully the new replacement will be fine. I am keeping my fingers crossed. But at this low of mileage I think the whole car should be replaced.
Lack of rattles, good gas mileage, good power.
Very hard to see out the back window with a spoiler especially when backing up.
