2: Chevrolet Cobalt
When the Cobalt hit the market, it was the replacement for the long-running Cavalier compact car. The Cavalier had been a great seller for GM and one of the most well-known cars on the road at the time. The Cobalt had some big shoes to fill and for the most part, the car was a decent offering (via Motor 1).

However there were reliability issues with the Cobalt, which makes it an expensive car to own. The coolant system has a lot of faults and it tends to be an expensive repair. The AC system is yet another expensive repair on the Cobalt, making this Chevy model one that wrecks drivers’ budgets to keep on the road.
