Like passenger cars, your conversion van is always susceptible to factory recalls. A quick review of the type and number of recalls may also give an indication about the reliability of the cargo van and the safety concerns of car company.
Worrisome examples are the two 2015 Ford Transit recalls soon after its introduction and even more for the Ram ProMaster. Although these safety recalls are taken more seriously lately, they should be taken into account during the purchase process of a new cargo van.
An overview of recent recalls of the Transit, ProMaster, Express, NV and Sprinter can be found at Cargo Van Recalls.
