Fuel pump failure on the 2012 Jeep Wrangler
When fuel pump failure gets reported
Owners of the 2012 Jeep Wrangler report fuel pump failure at a median of 65,000 miles. A quarter of the reports come in before 50,000 miles and a quarter after 80,000 miles, from 10 reports that carried an odometer reading.
A part like this is normally expected to survive 85,000 miles. It is the 19th most-reported problem on this model year.
The mileage distribution
The reported range runs from 45,000 miles at the tenth percentile to 80,000 miles at the ninetieth, a spread of 36,100 miles across the middle 80% of reports.
A window that narrow is the signature of a part that fails on its own schedule rather than on how the car is driven — which is usually a design or supplier problem rather than wear and tear.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 42,900 miles | 47,925 miles | 65,875 miles | 78,000 miles | 79,000 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 $600–$2,600 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 16 model years of this car. It shows up earliest on the 2013, at a median of 10,000 miles, and latest on the 2016 at 375,000 miles.
By volume the 2006 carries the most reports, with 23; the 2012 has 12. 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.
Tipm failure. Failure also affected starter and steering module. Initially vehicles lights and horn would go on without vehicle turned on. Doors lock and unlock by themselves. Ac and heater would shut down and restart. On these instances, dealership was advised, I was told that it was a code problem and codes were reset. Lately vehicle would downshift to first gear at both high and slow speeds causing a hazard in traffic. From a start position vehicle would not shift out of first gear. Vehicle engine would die out in traffic or turnover then die out as if fuel pump was failing. Instrumentation panel would flash and malfunction not allowing driver to see what gear indication was showing. Vehicle power steering would fail at various speeds causing dangerous situations. Last instance the vehicle was towed to dealership due to the unsafe conditions. Dealership and chrysler advised. Remedy from each is "we are looking for parts, do not know when or can give you a repair date. Vehicle has been at dealer since being towed in. Chrysler refuses to give any assistance. Initial cost of repair quoted at $1100.00+. Owner refused to pay this…

How far this goes
Complaints are voluntary, so 12 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 fuel pump failure happen on the 2012 Jeep Wrangler?
Across 10 owner reports that included an odometer reading, half were filed by 65,000 miles. A quarter were filed before 50,000 miles and a quarter after 80,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is fuel pump failure on the 2012 Jeep Wrangler?
12 reports have been filed with NHTSA, about 0.1 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.
