In owners' own words
Late 2011 my car starting having issues with the rpms going up and down while I was driving at a steady pace. By dec 2011 my car smelled like it had a small fuel leak; one that I could only smell while my car was idling.
Ignition switch jams; air bag light stays on; cruise control stopped working; airconditioner stopped working; tire light stays on; engine light stays on; and now heater is barely working.
My fuel pump was leaking, so we had the fuel pump replaced and now the air conditioning/heater/defrost systems no longer work.

Recalls for the 2008 Chevrolet Cobalt: 5
The weight on the key ring and/or road conditions or some other jarring event may cause the affected ignition switches to move out of the run position, turning off the engine and disabling the air bags. If the ignition switch moves from the run position to accessory, the car would stall and the air bags will not deploy in the event of a crash, increasing the risk of personal injury to the occupants.
In the affected vehicles, the key can be removed from the ignition when the ignition is not in the "Off" position. If the key can be removed from the ignition when the ignition is not in the "off" position, the vehicle could roll away: (a) for an automatic transmission, if the transmission is not in the "Park" position…
This defect can affect the safe operation of the airbag system. The key fob (if applicable), should also be removed from the key ring. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine. If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
Some of these vehicles have a condition in which the plastic supply or return port on the fuel pump module may crack, which could cause a fuel leak. Fuel leakage in the presence of an ignition source may result in a fire.
The driver may experience a sudden loss of power steering assist that could occur at any time while driving. If power steering assist is lost, it would require greater driver effort at low vehicle speeds, increasing the risk of a crash.
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
