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. Shakes violently after driving about 30 minutes on the highway. Does not do this just around town 4 or 5 miles from home. Dealer cannot reproduce this shaking problem nor can they find the problem. It shakes so bad that I am afraid to drive into the city. I do alot of business in the city so I am at a loss as to how I am going to work. I am an independent sales person.

2006 Cobalt had vibrations at highway speeds. Customer states if they stop and turn the vehicle off and on it will temporarily correct the vibration problem. The consumer stated since purchasing the vehicle, the vehicle has had an extreme vibration at high speed. The consumer stated the vehicle has become so dangerous and hard to drive that at times he would have to pull over to the shoulder. The consumer stated after several attempts to assess the problem balancing the tires and replacing 2 of the 4 tires, he was informed by dealer the rotors were out of round and left tire was worn. The consumer stated due to the fact the 2 Chevrolet dealers were given ample time to assess the problem, he feels this should fall under the lemon law of a refund or a replacement car. New tires were placed on the vehicle and balanced.

ABS light continues to come on first couple times dealer could not duplicate the problem. Finally light came on as I was leaving I called the dealer and told them I was coming right then before I shut my car off again for them to put it on the computer. Put car on comp, and got to codes both were something about a pump relay motor. Was fixed and then about 3 weeks later scheduled 3 rd appt for shaking problem and oh the ABS light came on again. 1 St appt for shaking said rotors needed turned with 17000 miles told them I was not paying for it called GM 800 number told me I lived in a hilly area round flat area. Took it to another dealer and they turned them under warranty. 4000 miles later took it back for steering wheel shaking on Tuesday. Wednesday they called to tell me I needed 4 new tires, new pads, oh and new rotors, not under my warranty wrong again I will not pay for all of these new at 21000 miles crazy. Today Friday I called to check on my car and was informed that there 30 year technician and service manager have been on the phone with tech support for two days and they told them they were on their own. If these mechanics have to use a phone to get information about a car they are either not a very good mechanic or maybe we are relying to much on computers to run our cars.
