Known issues on the 2022 Savana 2500. Twenty-seven owner complaints are logged for the 2022 van, and they gather in three places: the electrical system, the power train and the steering, in that order and close together. That distribution points a technician at the body and powertrain wiring diagrams first, then at the transmission and driveline diagnostic sequences with their measured specifications, then at steering linkage condition and torque figures. All three areas are covered here procedure by procedure, with the specifications printed beside the steps that use them.
