“Purchased a new 2015 PROMASTER 2500 in 2015 and experience engine problems after 2 years. In 2020 fuel injection and engine cooler fan issues. Each time the light bulbs (headlights) are changed they go out within a few months. I'm scheduled for a few recalls and waiting for the parts to come in for the engine cooler fan and the shift cable. I would never buy a dodge Ram truck again.”

An independent mechanic arrived at the residence the next day and diagnosed that there was a wiring failure and the power control module had failed. …”
