Notes: The 2006 Cobalt continued to carry the torch first lit by the 2005 model year. To be clear, that torch is burning bright with widespread power steering issues, electrical curiosities and a dangerous ignition switch defect which led to a massive recall by GM. This isn’t a great torch to carry.

The 2006 added it’s own special flare with gas leaks due to cracks in the “return portion of the modular reservoir assembly.” A recall of 2006 Cobalts was issued to fix the problem, but only to vehicles sold in or current registered in Arizona and Nevada, leaving other owners to pay for repairs themselves.

Between this car stalling while driving, giving owners fits with power steering failure and having it be a potential tinderbox because of gas leaks, we felt we had no other option than to award it our “Avoid Like the Plague” badge.

I see there are issues on the fuel module on the 2006 Chevy Cobalts, and I took it to get replaced however when I take my car to get diagnosed it continues to say there is something with a misfire, and my fuel evaporating. I am having multiple problems with my 06 Cobalts and has I have done extenuous research and every problem I've found online over 1000 complaints and blogs, and sites where customers are all complaining about the same issue. I am a working college student and drive to work and school everyday. My car stopped on the freeway the other day, and almost caused an accident however the vehicle slammed on their brakes. Not only the fuel line but also my car key does not come out the ignition. All these issues are ongoing and I have found over 10,0000 unsatisfied consumers all with the same issues with the Cobalts. This is a big issue, and I am tired of dealing with Chevrolet as this is there product and they are only trying to get the money and make you pay for all the services. These are major issues all going out at the same time.

Exhaust - muffler - went to 3 different service places and the baffles in the muffler are bad and rattling around inside the muffler. None of the commercial service places are able to put a new muffler on as Chevy has not released the muffler to my 2006 Chevy Cobalt ss - called the dealership and they say it is not covered under my extended warranty - the car is only 3 years old and has not been in any accidents. Dealership does not stock this muffler and wants almost $550 just to replace the muffler. I will be looking for a new car and not a Chevy!!
