Other fuel system problem on the 2018 Jeep Grand Cherokee
3 crashes 1 injury 4 of the 34 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 2018 Jeep Grand Cherokee report other fuel system problem at a median of 5,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 30,000 miles, from 17 reports that carried an odometer reading.
A part like this is normally expected to survive 90,000 miles. It is the 6th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 40,000 miles at the ninetieth, a spread of 36,020 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.
82% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 3,060 miles | 3,800 miles | 6,000 miles | 29,200 miles | 39,080 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, 3 a crash and 1 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 2018 has 34. 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.
Driving the auto and applied the brakes at a red light and the brakes only partially engaged and the auto went through the red light. Drove up to the next light as the car was just about to stop it accelerated forward into the truck in front of me. There is a safety feature called "forward collision warning" which should apply the brakes and did not work (instead of braking with the jeep safety feature the auto accelerated). The dealer repaired the damage paid by my insurance company but could not tell me why this happened or provide assurance that it would not happen again. The insurance company said they would investigate with the ntsb and review the "black box". If the truck was not in front of our vehicle we would have gone through the red light into a highway intersection. The car had slowed to 5 MPH and was ten feet from auto in front and then accelerated to about 15 MPH in a few seconds.

My car was parked outside of one of the steel sheds. When rain started we decided to drive my car around and under the shed. I took the car around but couldn't quite make it into the shed and had to back up. When shifting into reverse I heard a strange noise and my friend told me later that my rear wheeles started spinning, which they are not supposed to do. When my car was in the right position my foot was still on the break I shifted to "drive". At this moment the engine roared up and raced forward. I could not stop the car. I steered it into the next empty shooting bay in 1/2 circle into the…

How far this goes
Complaints are voluntary, so 34 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.

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.
