Each year is complaints filed in that year’s first 3 years on the road, divided by however many of those years have passed. A model year younger than 3 years is too early to compare, so it is left out of the years named as having the fewest or the most complaints. Recalls are a separate count. The numbers are for the US-market Ram 4500. How we count.

Known issues for this generation

Recall 18V-277 covers certain 2018 Ram 4500 and 5500 cab chassis trucks: the primary and secondary brake hoses between the brake master cylinder and the hydraulic control unit may have been manufactured incorrectly and could leak brake fluid, which can reduce braking performance and increase crash risk. Dealers inspect the hoses and replace them if necessary. Recall 21V-398 also covers certain 2012-2021 Ram 4500 cab chassis vehicles: incorrect lug-nut torque information in service and owner's manuals may cause flanged lug nuts to be undertorqued; dealers update the published torque specification and inspect wheel studs.
