Other speed control problem on the 2015 Jeep Grand Cherokee
11 crashes 1 fire 1 injury 13 of the 30 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 speed control problem gets reported
Owners of the 2015 Jeep Grand Cherokee report other speed control problem at a median of 32,500 miles. A quarter of the reports come in before 5,000 miles and a quarter after 50,000 miles, from 26 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 7th most-reported problem on this model year.
The mileage distribution
The reported range runs from 2,500 miles at the tenth percentile to 67,500 miles at the ninetieth, a spread of 66,011 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.
58% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 1,850 miles | 5,125 miles | 32,000 miles | 50,000 miles | 67,861 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, 11 a crash, 1 a fire 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 $250–$2,000 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.
This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.
The same failure on other years
The same failure is reported on 28 model years of this car. It shows up earliest on the 2020, at a median of 2,300 miles, and latest on the 1998 at 125,000 miles.
By volume the 2005 carries the most reports, with 58; the 2015 has 30. 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 was driving down the road, with my foot steady on the gas, and the transmission shifted hard (8 speed automatic) and lunged my car forward without any pressure on the gas pedal. Then it continued to shift hard and lunge until I reached and maintained 40 MPH ( in which my jeep put the transmission into 8th gear at a steady 1000 RPM). This has happened multiple times since, and sometimes when I remote start the jeep, it will give off a very loud high pitched whining sound for about a minute, then stops. *tr
Third time of incident. While parallel parking, and shifting from reverse into drive, while foot is still on the brake the vehicle revs and lurches forward. 1st 2 times involved parking on snow/ice. Today, with a dry street and sneakers, vehicle began to rev. I attempted to shift into park to avoid lurching forward but failed to do so in time. When vehicle revs, I hold onto steering wheel and press brake with all my strength but unable to prevent the forward movement. *tr
Tl* the contact owns a 2015 jeep grand cherokee. While driving at various speeds after disengaging the accelerator and brake pedals, the vehicle accelerated without any control. The vehicle shifted into different gears independently without warning. The vehicle was not diagnosed. The vehicle was repaired, but the failure persisted. The manufacturer was made aware of the failure. The failure mileage was 4,000.

How far this goes
Complaints are voluntary, so 30 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 speed control problem happen on the 2015 Jeep Grand Cherokee?
Across 26 owner reports that included an odometer reading, half were filed by 32,500 miles. A quarter were filed before 5,000 miles and a quarter after 50,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other speed control problem on the 2015 Jeep Grand Cherokee?
30 reports have been filed with NHTSA, about 0.3 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.
