Known issues on the 2012 Savana 1500. A single owner complaint is logged with NHTSA against this model year, and it concerns the fuel and propulsion system. That is the part of the van the manual treats most closely, because two different engines and a flex-fuel calibration have to be diagnosed with the right pressure specifications, injector and pump tests and torque values. Beyond it, the transmission and driveline, hydraulic brakes, suspension, steering, restraints, body and electrical systems each have their own procedures, wiring diagrams and specifications.
