Other fuel system problem on the 2012 Dodge RAM 1500
When other fuel system problem gets reported
Owners of the 2012 Dodge RAM 1500 report other fuel system problem at a median of 80,000 miles. A quarter of the reports come in before 55,000 miles and a quarter after 135,000 miles, from 17 reports that carried an odometer reading.
A part like this is normally expected to survive 90,000 miles. It is the 8th most-reported problem on this model year.
The mileage distribution
The reported range runs from 20,000 miles at the tenth percentile to 155,000 miles at the ninetieth, a spread of 135,334 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
18% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 20,866 miles | 57,000 miles | 80,000 miles | 135,000 miles | 156,200 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Putting it right typically runs $300–$2,200 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 15 model years of this car. It shows up earliest on the 2002, at a median of 100 miles, and latest on the 1996 at 155,000 miles.
By volume the 2008 carries the most reports, with 32; the 2012 has 31. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
Engine idle spiked and dropped in rush hour stop and go traffic until the truck eventually stalled. I placed the truck in park and tried restarting. The "electronic throttle control" light illuminated in the dash. I turned the truck off and tried restarting. The starter turned over but the truck acted as if an element needed for combustion was missing. I turned my hazards on--as traffic was clearing around me. I tried starting the truck a dozen times before calling 911 (since I was in the middle of an interstate hwy). I texted a friend who said try starting with the accelerator pedal fully depressed--the truck started, but then went right back to spiking idle and the engine died again. At this time traffic was speeding by so fast on both sides that I could not exit the vehicle. State patrol came to push me to the shoulder. Truck started again on the shoulder after several attempts and I managed to move it about 50 feet before it died again. Had truck towed to nearest dealership where they informed me it may take up to 2 weeks before they can diagnose my truck. Still under warranty. Second time this has happened with this vehicle…
Currently, when getting into vehicle we have been having issues starting the truck. It has even stalled out on us while driving on the interstate. Tood to dealership and due to the check engine light not being on they informed us they were unable to do the dionogstic test.
Tipm failed to work correctly resulting in no fuel pressure periodically and without warning. Engine would fail to run. Sometimes it would be ok and then sometimes the engine would not run. Ram said they would have to locate a new tipm. They didnt have one because of alot of these had failed, so theyre in high demand. Why arent these being recalled then??

How far this goes
Complaints are voluntary, so 31 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does other fuel system problem happen on the 2012 Dodge RAM 1500?
Across 17 owner reports that included an odometer reading, half were filed by 80,000 miles. A quarter were filed before 55,000 miles and a quarter after 135,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other fuel system problem on the 2012 Dodge RAM 1500?
31 reports have been filed with NHTSA, about 0.4 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
