Questions to ask the seller
- Were recalls 25V876000 (equipment adaptive/mobility), 25V720000 (engine) and 25V552000 (back over prevention) done? It has 5 recalls in all. Ask for the dealer printout, or check the VIN.
- Any slipping, hard or late shifts, or a transmission warning light? Ask for transmission fluid service records.
- Do all the seat belts latch and retract?
- Ram sent dealers 228 repair notes for this car. Was this one done: “SEAL, Input If looking to replace stubshaft due to ATX fluid leaking, do not replace PTU seals”?

How serious. Out of all 14 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

When owners reported problems. From owner complaints to the government.
Most owners who filed a complaint with NHTSA had 2K to 19K miles (4K to 31K km) on the car (6 of all 14 complaints filed so far listed the miles). This shows when people who had a problem reported it, not the odds that your car will have it.
In owners' words
Second row seat belts remain in a locked position and do not pull out, are inoperable, and remain in a locked position, thus there is no way for us to use our seatbelts. This is an extreme safety issue.

Newest year first. Red = worse than average, gray = about average, too new (2023+: a partial score, marked “partial”) or too few complaints to score. #1, #2… = that year's YouTube rank among the 9 Ram ProMaster years with enough videos (#1 = the year owners and reviewers talk about most positively). It is not a reliability rank.

It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
