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.

2006 Chevrolet Cobalt Owner Comments

problem #1

Apr 202007

Cobalt 4-cyl

  • Manual transmission
  • 15,000 miles


I purchased a 2006 Chevy Cobalt ss w/ 2.4 liter non-supercharged engine. At about 5,000 miles the car began shaking while braking. I took the car to the dealership and they informed me that the front rotors were delaminated and they machined them down smooth again. This fixed the problem for about another 5-600 miles, then the shaking started again. My car had to go back to the dealer again and they machined them down again without replacing the rotors-they said they just pass inspection. Also, they informed me that the head gasket, the valve covers and the exhaust manifold all needed to be replaced. This is the sixth day they had my car and everyday it is something else they find wrong with it. My car only has 15,000 miles on it and is well taken care of. I feel that the braking power of the car is decreased, even after the rotors are "fixed", I fear I may get into an accident because of this and no one at denoyer Chevrolet on wolf rd in albany, NY tele#518-458-7700 cares. The person that is updating me with information on my car is jeff winne and he is very rude. I hope this matter can be further investigated to prevent any further injury.
