Mossy Chrysler Dodge Jeep Ram Service Center on Auto Park Avenue in Chula Vista maintains Chrysler, Dodge, Jeep, Ram, and Wagoneer vehicles from a facility that the Mossy Automotive Group built from the ground up in December 2022. The service department stocks Mopar OEM parts and runs manufacturer diagnostic software for warranty claims, recall campaigns, and factory-scheduled maintenance, drawing inventory from the adjacent Mossy Chrysler Dodge Jeep Ram showroom and parts counter. Part of a veteran-owned, 17-location Mossy dealership network rooted in San Diego County since July 1982, the Chula Vista facility anchors the Auto Park Avenue cluster near I-805 alongside neighboring Nissan and Toyota service bays. Post-collision electrical and ADAS recalibration reports feed downstream to structural repair shops at Caliber Collision when frame or panel damage requires certified body work beyond the service department's mechanical scope. Top-tier procedures include Jeep Wrangler JL Dana 44 axle seal and bearing replacement, Ram 1500 EcoDiesel 3.0L turbo diesel fuel system priming, and Dodge Charger Hellcat 6.2L supercharger belt tensioner service at 720-horsepower output loads.
