Is the 2020 RAM ProMaster reliable?

It can be reliable for commercial use when maintenance is kept up, but it’s best viewed as a hardworking fleet-style van where uptime depends on preventative service and quick attention to warning signs.

What are the most common 2020 RAM ProMaster problems?

What should I check before buying a used 2020 RAM ProMaster?

Verify maintenance records, scan for powertrain and body module codes, test for smooth transmission engagement, inspect for coolant leaks and overheating history, check tire wear/alignment, and confirm all electrical features work (lights, locks, infotainment, camera).
