Other fuel system problem on the 2008 Jeep Grand Cherokee
Only 5 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When other fuel system problem gets reported
There are 6 reports of other fuel system problem on the 2008 Jeep Grand Cherokee, 5 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 90,000 miles. It is the 26th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 82,000 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 $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 2008 has 6. 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.
While sitting at a stoplight, on two (2) occasions my 2008 jeep grand cherokee 4x4 suddenly accelerated on its own while my foot was on the brake and revved up (throttle surge), then the tach went back to normal, and the engine went back to idling. Took it to the dealer I bought it from, they checked the on-board computer and no incident showed; they told me they called chrysler but no one has reported this before and no technical bulletin has been issued regarding throttle surge issues. Have only had the vehicle 11 months. Now at times, while stopped and idling, the engine will act like it's going to cut off as the idle drops for a few seconds. Dealer also did not find an issue in the computer with this problem when I took it in a second time. *tr
So the starter has been a issue ever since I bought the car from my father 2 years ago. The key seems to be the problem since I got the starter rebuilt. It just doesn't start and will turn off at times for no apparent reason which would scare everyone in the car. I was wondering if there is a recall because there should be. *tr
Vehicle turned off while driving down the highway. Lost power steering and power brakes and came to rest in the middle of the highway. Vehicle indicated problem was failed electric throttle control. Problem reoccurred 8 times while driving the vehicle to the dealer for service. Vehicle would start and go and would then shut off randomly. Major safety issue.

How far this goes
This page is kept out of search results because 6 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 6 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 2008 Jeep Grand Cherokee?
Across 5 owner reports that included an odometer reading, half were filed by 80,000 miles. A quarter were filed before — and a quarter after —. 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 2008 Jeep Grand Cherokee?
6 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.
