Other powertrain problem on the 2018 Jeep Grand Cherokee
5 crashes 3 injuries 8 of the 42 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 powertrain problem gets reported
Owners of the 2018 Jeep Grand Cherokee report other powertrain problem at a median of 17,500 miles. A quarter of the reports come in before 5,000 miles and a quarter after 35,000 miles, from 29 reports that carried an odometer reading.
A part like this is normally expected to survive 92,000 miles. It is the 5th most-reported problem on this model year.
The mileage distribution
The reported range runs from 2,500 miles at the tenth percentile to 95,000 miles at the ninetieth, a spread of 92,491 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.
72% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 3,243 miles | 4,000 miles | 16,961 miles | 36,000 miles | 95,734 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, 5 a crash and 3 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 $400–$4,500 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 30 model years of this car. It shows up earliest on the 2020, at a median of 5,000 miles, and latest on the 1996 at 110,000 miles.
By volume the 1998 carries the most reports, with 352; the 2018 has 42. 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.

Transmission problems. The transmission shifts are pronounced, cause the SUV to jerk and feel jumpy. This condition is sporadic, and can change based on mode - normal, eco off, sport . Besides causing a choppy ride, the condition is concerning because some shifts that cause the vehicle to jerk are accompanied by a banging noise that may be a r a precursor to gear failure.

How far this goes
Complaints are voluntary, so 42 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.
