Recalls for the 2005 Saturn ION: 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…
In the affected vehicles, there may be a sudden loss of electric power steering (EPS) assist that could occur at any time while driving. If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash.
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.
These headlamps fail to conform to the requirements of federal motor vehicle safety standard no. 108, "Lamps, reflective devices, and associated equipment." These lamps do not contain the required amber side reflectors. Decreased lighting visibility may result in a vehicle crash.
