Official recalls have been issued for the 2007 Saturn Ion by the NHTSA. The complete details of all recalls are listed below, along with what they cover and the recommended solutions.
Summary: General Motors LLC (GM) is recalling certain model year 2005-2010 Chevrolet Cobalt, 2006-2011 Chevrolet HHR, 2007-2010 Pontiac G5, 2006-2010 Pontiac Solstice, 2003-2007 Saturn Ion, and 2007-2010 Saturn Sky vehicles. In the affected vehicles, the key can be removed from the ignition when the ignition is not in the "Off" position.
The standard engine provides adequate, if not entirely refined, power throughout the rev range. The optional 2.4-liter is not the pinnacle of smoothness either, but provides gutsy performance for a car in this class. The four-speed automatic transmission is responsive, and the best choice for most buyers. The manual box gives the car a sportier feel, but it's a little rough through the gates. The ride is soft enough to soak up rough roads, yet the 2007 Saturn Ion still handles itself well in tight turns and on freeway off-ramps.
