Print this page Notes: The Cobalt was introduced to replace two of Chevy’s smaller cars, the Cavalier and Prizm. But the compact’s fresh start that Chevy was hoping for was riddled with issues, most notably widespread power steering failure.

The power steering failed so often that GM was forced to issue a recall in March, 2010. Great, but what about other problems like the key getting stuck in the ignition or all the other electrical demons this car possesses?

And, oh yes — then there’s the terribly dangerous issue where the Cobalt randomly shuts off while driving. As it turns out, that problem is related to GM’s massive 2014 recall for a dangerous ignition switch defect. A recall that eventually ballooned to 2.6 million vehicles in one of the automotive industry’s biggest scandals.

I bought the car new at a dealer in Burlington, NC. I always kept up on oil changes but when the car started making clanging noises and running rough I took it to the dealer. He told me that I had a bad build-up of engine sludge and may need a new engine. He told me that it was probably caused by using the wrong oil (I usually use Pennzoil). Other than that I can't get any satisfaction from the dealer or any other assistance. BUT>>they would be willing to take it in as a trade IF I BUY A NEW ONE!!

Sorry, but it sounds like BS to me. After reading about all the other complaints in your website, I'd say there was something wrong with the engine which GM should be responsible for. Bad engine, but a real good time for them to stand behind their product!!
