Other speed control problem on the 2018 Jeep Grand Cherokee
7 crashes 6 injuries 13 of the 22 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 2018 Jeep Grand Cherokee report other speed control problem at a median of 5,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 20,000 miles, from 19 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 10th most-reported problem on this model year.
The mileage distribution
The reported range runs from 1,200 miles at the tenth percentile to 30,000 miles at the ninetieth, a spread of 31,160 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
95% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 1,240 miles | 3,693 miles | 6,100 miles | 21,277 miles | 32,400 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, 7 a crash and 6 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 2018 has 22. 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.
Tl* the contact owns a 2018 jeep grand cherokee. While driving 45 MPH, the accelerator pedal was depressed, but the vehicle failed to accelerate. The vehicle was taken to john hiester chrysler dodge jeep ram (940 n main st, lillington, nc 27546, (910) 893-8088), but the failure could not be duplicated. The manufacturer was made aware of the failure. The failure mileage was 3,500.
On occasion, when the accelerator pedal is pushed all of the way to the floor, it would get stuck under the floor mat. This has happened on more than one occasion. It is very dangerous when it happens because the vehicle is at full throttle and the brakes will not overcome the engine. I've resolved the problem in my vehicle by removing the floor mat. I called jeep cares and warned them of this problem and they said to take to a dealership to have it looked at. They've known about it for a couple of weeks. I'm reporting this with the hope that you will look into this and get a warning out before someone gets injured or killed. Thank you, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *cc *tr *dt updated 10/29/18*jb
Throttle has stuck on full throttle 2 times while accelerating on city street. The only way to slow vehicle down was to put transmission in neutral and apply brakes hard. Very scary situation! Other owners have had the sane problem. *dt consumer stated other owners have told me they have experienced stuck throttles also. 2017/2018 jeep cherokee srt with 6.4 litre hemi engine and 2018 jeep grand cherokee trackhawk with supercharged 602 hellcat hemi engine. I know of one person that has filed a claim with the NHTSA. I've attached 2 pictures of my throttle pedal and floor mat. When fully depressed it does not touch the floor mat. I pushed on it a hundred times and it did not stick. I do not believe the floor mat is the problem. I had it at the dealer and they could find nothing wrong. Very scared to drive. Updated 10/18/18*jb

How common is other speed control problem on the 2018 Jeep Grand Cherokee?
22 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.
