Known issues on the 2013 Express 1500. Twenty-two complaints stand on record for this model year, service brakes and the electrical system tied at five apiece and air bags at two. Brakes and electrics overlap more than the categories suggest, since anti-lock function, the stop lamp switch and the warning lamps all run through shared circuits. Hydraulic brake service and friction specifications, wiring diagrams with ground and connector locations, and the supplemental restraint diagnostic sequence are all present, with torque values given for the fasteners each of those jobs disturbs.
