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.

problem #1

Cobalt 4-cyl

  • 45,983 miles
While driving down highway the traction control light came on. When I slowed to exit highway my vehicle began to shift funny and hard and became scarry. I then left stop sign and my car was shifting hard and felt like it was jumping eraticly. I was scared to drive at times and it continued for about an hour then I pulled into get something to eat and call my husband. After eating and telling my husband, I got back into car and it was fine. No more lights on the dash saying service engine soon or traction control light. It was fine for the rest of my way home. I went to work next day and all was back again, light for service engine came on and so did traction control. Then my car started jerking again and shifting real hard. Now my car does this at least 4 times a week. I had it looked at and they could not find anything they said. It happened again and I took it in and they said it was a front right wheel bearing showing up on code but nothing else. Had the bearing fixed and it still does it. I should have known that wasn't all it was cause it feels like the trans slipping and grabbing. To this day it still does it with everyone telling me they can't find problem.
