The GM ignition-switch defect is the most consequential single defect of the modern recall era, and it traces back to a ten-cent part. The switches in 2003-2011 GM compacts — Chevy Cobalt, HHR, Saturn Ion, Pontiac G5 and Solstice, Saturn Sky — were spec'd to a torque below GM's own internal standard. Hit a bump with a heavy keychain hanging off the key, brush the key with a knee on the way in or out of the seat, and the switch could rotate out of "Run" into "Accessory" at highway speed. That cut power to the airbags, the power steering, and the ABS, all at once. GM engineers knew the part was out of spec by 2005. The recall came in 2014, ten years later. By then NHTSA's investigation had tied the defect to over a hundred deaths and at least that many serious injuries. GM paid the Department of Justice $900 million in a deferred prosecution agreement and ran its own victim-compensation fund. The mechanical fix is straightforward: a free dealer replacement of the ignition switch and a new key. Almost every affected vehicle had the work done by 2017. The risk on the used-car market today is the small minority that didn't — owners who never got the recall letter, vehicles that changed hands without records, or cars where the wrong-spec replacement was installed.

Common questions
How do I know if the recall was done on my Cobalt?
Run the VIN through NHTSA's free recall lookup at nhtsa.gov/recalls — campaign number 14V-047 and the related expansions are what you're looking for. The site tells you definitively whether the work was performed. A GM dealer can also pull the VIN's service history if you want a second confirmation.
Was the heavy keychain really the problem?
It was the trigger, not the root cause. The root cause was an under-spec ignition switch that GM specified and built knowing the torque was below their own internal standard. A heavy keychain on a normal car would never cause an issue; on these GM cars, a moderate keychain plus a bump was enough to swing the key out of "Run." GM fixed both — replaced the switch and issued new, lighter-friendly keys.
Should I buy a used Cobalt, HHR, or Saturn Ion?
With the recall confirmed done, yes — these are cheap, basic, reliable transportation. The 2.2L and 2.4L Ecotec engines are durable. Cobalt and HHR in particular are some of the lowest-cost one-owner used cars on the market. Without the recall confirmed, walk away — the ignition risk aside, you don't know what else the prior owner missed.
