Known issues on the 2015 Savana 2500. Three owner complaints are recorded for this model year, one each against the air bags, visibility and exterior lighting. All three sit on the electrical side of the van, and the manual treats them there, with restraint system diagnostics and their service warnings, wiper and washer circuit tracing, and lamp, socket and ground checks read off the body wiring diagrams. The associated component specifications and fastener torque values are printed with those procedures, which is what keeps a small fault from turning into a parts-swapping exercise.
