Known issues on the 2012 Savana 2500. Three owner complaints are recorded for the 2012 van, two against the air bags and one against visibility. Both headings are as much electrical as mechanical on this platform, and the manual treats them that way: the supplemental restraint system has its own diagnostic procedure, wiring diagram and set of service warnings, while wiper, washer and lighting circuits are traced through the body wiring schematics. Torque values for the related fasteners sit with the procedures themselves rather than in a separate table.
