2020 Ram ProMaster Model Year Overview

Without the discontinued diesel, 2020 buyers received the Pentastar V6 for delivery, trade, and camper applications. Those uses often involve high payloads, stop-and-go miles, and aftermarket electrical loads beyond typical passenger-vehicle demands.

Known Issues on the 2020 Ram ProMaster

Pentastar Rocker Arm and Lifter Tick

Rocker arm or lifter wear can create a persistent tick and require valvetrain work costing $1,500–$3,000.

Owner forums, service discussions, and NHTSA-style complaint patterns regularly cite ticking and valvetrain concerns among higher-mileage Pentastar-equipped commercial vans, where long hours and frequent starts add stress.

Alternator Failure Under Heavy Loads

Lighting, refrigeration, shelving accessories, and fleet equipment can increase electrical demand. Alternator replacement typically costs $500–$900.

Front CV Joint and Half-Shaft Wear

Heavy cargo and repeated turns can accelerate front half-shaft wear. Repair per side commonly costs $400–$800.
