2015 RAM Promaster at 39,025 miles

You did not give a mileage, so this uses 39,025 — the median reported failure mileage for this model year, which is a rough stand-in for “a typical example of this car”. Put your real reading in the box below for an answer about your car.

Rounds to

At 39,025 miles on this car

At 39,025 miles on a 2015 RAM Promaster, 13 of the failure modes other owners have reported already have their median report at or below your reading, and 0 more fall inside the window where they are usually reported. The heaviest of the ones already due is other engine problem.

Already past the median 13

Half of all reports of these failures came in at or below where your car is now.

  • Other engine problem 2k
  • Other electrical problem 7k
  • Stalling while driving 11k
  • Control module (ECM/PCM/BCM) failure 23k
  • Other fuel system problem 10k
  • Other brake problem 37
  • Other speed control problem 5k
  • Instrument cluster or gauge failure 2k
  • Cruise control failure 250
  • Other visibility problem 22k
  • Loss of braking 10k
  • DPF, EGR or DEF system failure 39k

Your reading falls inside the middle half of reports for these.

Reported, but too few owners gave an odometer reading to place them.

Why the list is generic until you type a number

Every figure below is a comparison against your odometer, so with no reading given the page has to pick one: 39,025 miles, roughly what a 2015 car covers at 12,000 miles a year. A reading 30,000 miles either side of that moves failures between the columns, which is the difference between a useful list and a generic one.

Already inside the reported range

13 failure modes on the 2015 RAM Promaster have a median reported mileage at or below 39,025: other engine problem (median 2,400 miles, 8 reports), other electrical problem (median 5,000 miles, 4 reports), stalling while driving (median 10,000 miles, 3 reports), control module (ECM/PCM/BCM) failure (median 25,000 miles, 3 reports), other fuel system problem (median 10,000 miles, 3 reports) and other brake problem (median 37 miles, 3 reports).

Half the owners who reported each of these had done so by that mileage, which means half had not. A failure being "due" here is a statement about other people's cars, and the useful response is an inspection rather than a pre-emptive repair.

Still ahead of you

8 further modes sit above your reading, the nearest being tire pressure monitor failure at a median of 40,000 miles. On a car you intend to keep, these are the ones that decide whether it is worth keeping.

What this list is not

It is a reading of what owners of other 2015 RAM Promasters reported, and at what odometer reading they reported it. It is not a maintenance schedule, not a diagnosis, and not a prediction about this car: two identical cars with different service histories are not the same car.

Complaints are filed voluntarily, mileages are typed in by owners and cluster on round numbers, and a failure mode with few reports has a wide window even when the median looks precise. Modes with fewer than 8 dated reports are shown without percentiles for that reason.

Where 39,025 miles falls on the curve

The three columns above sort the failure modes one by one. This is the same evidence in aggregate: every dated report on this model year, stacked up in the order the odometer readings arrived. The dashed line marked you is where your car sits. How much of the line is to the left of that mark is how much of this model year's reported trouble is, on the evidence, already behind you.

Share of reports filed by each mileage, with your reading marked
you: 39k

About 44% of the dated reports on this model year had already been filed by 39,025 miles. That is the share of the problems that show up in this record, not of the problems this car will have. A further 1 report came in above the top of the scale, which is why the line stops short of the top.

  • Line share of reports filed by that mileage
  • Dashed the mileages called out above

A steep early climb means a car whose reports cluster young, which is the pattern of a defect rather than of wear. A line that only gets going past six figures is the opposite. Neither shape says anything about the specific car in your driveway, and a curve built from a few dozen readings can be moved by one owner with a talkative afternoon.

Questions this page answers

What should I expect at 39,025 miles on a 2015 RAM Promaster?

13 of the failure modes owners have reported on the 2015 RAM Promaster have a median report at or below 39,025 miles, and 0 more fall inside the mileage window where they are usually reported. That is a watch list drawn from other owners, not a prediction about this car.

How to use the three columns. The left column is the list to hand a mechanic before you buy, and to check the service history for if you already own the car. The middle column is what to budget for this year. The right column is not a reprieve — it is a reminder that a used car has a bill schedule, and this is roughly where it falls. All of it is drawn from 80 owner complaints about this exact model year, not from a maintenance manual. How the percentiles are computed.
