Known issues on the 2018 Savana 2500. Three owner complaints are recorded for the 2018 van, one each against the engine, the suspension and the service brakes. Spread that thin, they read less as a pattern than as a reminder of where a work van wears. The manual's answer to all three is the same in kind, a measured specification and a torque value with a diagnostic sequence attached: compression and oil pressure checks on the engine side, ride height and fastener figures on the suspension, and hydraulic pressure and clearance limits on the brakes.
