Other speed control problem on the 2006 Jeep Grand Cherokee
3 crashes 2 injuries 5 of the 28 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 2006 Jeep Grand Cherokee report other speed control problem at a median of 70,000 miles. A quarter of the reports come in before 55,000 miles and a quarter after 100,000 miles, from 25 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 14th most-reported problem on this model year.
The mileage distribution
The reported range runs from 20,000 miles at the tenth percentile to 140,000 miles at the ninetieth, a spread of 119,655 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
16% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 19,629 miles | 54,000 miles | 70,000 miles | 101,000 miles | 139,284 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 2 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 2006 has 28. 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 2006 jeep grand cherokee. While decelerating to 30 MPH in the rain, the contact approached a stop and the vehicle suddenly surged forward full throttle. He depressed the brake pedal with maximum pressure, but the vehicle would not stop. The contact merged into an intersection, barely missed another vehicle, and swerved into a driveway. He placed the vehicle into neutral and successfully applied the brakes. The dealer stated that they had never heard of this failure, but currently are keeping the vehicle for a diagnosis. After online research, the contact discovered numerous consumer complaints on unintended acceleration of his model vehicle. The current mileage was 20,325 and failure mileage was 19,382.

Stopped for gas. Started engine and there was great and unexpected acceleration. Had to maneuver to reach the exit area---kept my foot on the brake and went forward with the engine straining, put it in reverse, same thing. Couldn't 'de-accelerate'. Moved forward a bit and shut the engine off. If I was not quickly in control of that vehicle there would have been fatalities wrote chrysler and received a response that there were no recalls on this model. Took it to the local dealer service department. He put it 'on the computer' and by the end of the day found the problem. He discovered a service bulletin dated may 13, 2006 which applied to grand cherokees equipped with the 5.7l engine. It described the problem and the solution. This warranted a recall. Why couldn't the owners (lessees in this case) be notified to bring their vehicle in to correct a defective part of the vehicle computer (p2112). What a simple solution for a dangerous defect! *tr

How far this goes
Complaints are voluntary, so 28 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 2006 Jeep Grand Cherokee?
Across 25 owner reports that included an odometer reading, half were filed by 70,000 miles. A quarter were filed before 55,000 miles and a quarter after 100,000 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 2006 Jeep Grand Cherokee?
28 reports have been filed with NHTSA, about 0.2 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.
