Other fuel system problem on the 2012 Jeep Grand Cherokee
4 crashes 2 injuries 6 of the 87 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
When other fuel system problem gets reported
Owners of the 2012 Jeep Grand Cherokee report other fuel system problem at a median of 82,500 miles. A quarter of the reports come in before 47,500 miles and a quarter after 102,500 miles, from 54 reports that carried an odometer reading.
A part like this is normally expected to survive 90,000 miles. It is the 7th most-reported problem on this model year.
The mileage distribution
The reported range runs from 20,000 miles at the tenth percentile to 152,500 miles at the ninetieth, a spread of 130,700 miles across the middle 80% of reports.
When the reports scatter this far, the mileage is telling you about how these cars were driven more than about the part itself.
17% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 20,600 miles | 47,800 miles | 81,500 miles | 103,225 miles | 151,300 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
Of these reports, 4 a crash and 2 an injury are mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
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 24 model years of this car. It shows up earliest on the 2018, at a median of 5,000 miles, and latest on the 2000 at 155,000 miles.
By volume the 1997 carries the most reports, with 144; the 2012 has 87. 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.
I started the engine of my 2012 jeep and as soon I began traveling with the jeep fluids poured from the middle of the engine. I did not notice this until I stopped the vehicle after driving 10 minutes. The computer did not show any signs of an error or engine trouble. When I stopped the vehicle and looked under the front of the car I saw a steady stream of orange liquid pouring from the middle of the engine. This fluid was engine coolant. I immediately had the vehicle towed to a local chrysler service station. My jeep has been with the service department for over two weeks now. The jeep cannot be fixed due the fact that chrysler has no spare parts. *tr
This jeep has remote key-less entry/engine start. The engine cannot be turned off unless the gear shift is in park. If the throttle stays open causing unintended acceleration, one cannot turn the engine off. This could result in one or more deaths and/or serious injury! If one had an accident causing the engine to rev up due to a jammed gas pedal, how do one turn it off? Chrysler customer service was contacted about this issue and their response was "the characteristic you describe, however, is a function of your vehicle's design and there is nothing that can be done to ?fix? The condition." reference number: email case number: supplied upon request. In other words they don't care about this safety issue! I have another car that can have the engine turned off, but it is a standard transmission. Madza's can be turned off while in drive with automatic transmissions. This jeep was purchased in the usa. *tr
Multiple incidents - stopped at corner heading uphill. Happened to touch both brake and gas pedals at the same time. I found that when going into the intersection at the change of light, no gas (propulsion) for approx. 5 seconds. Complained to service mgr. He advised he had heard this before and would contact chrysler. Never heard from him again. Over the two years this problem occurred about 4 times. I have since been told that nissan has also engineered this into their cars as if this makes it right. *tr

How far this goes
Complaints are voluntary, so 87 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 Jeep Grand Cherokee?
Across 54 owner reports that included an odometer reading, half were filed by 82,500 miles. A quarter were filed before 47,500 miles and a quarter after 102,500 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 Jeep Grand Cherokee?
87 reports have been filed with NHTSA, about 1.0 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.
