Other speed control problem on the 2012 Jeep Grand Cherokee
5 crashes 2 injuries 7 of the 20 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 2012 Jeep Grand Cherokee report other speed control problem at a median of 50,000 miles. A quarter of the reports come in before 15,000 miles and a quarter after 105,000 miles, from 19 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 19th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 125,000 miles at the ninetieth, a spread of 119,081 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.
42% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 4,065 miles | 15,000 miles | 51,000 miles | 105,500 miles | 123,146 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 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 2012 has 20. 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 going approximately 20-25 approaching a signal light. I let off the gas and applied the brake as the light was red. As I let off the gas, the engine began to rev higher and as I applied the brake I had to apply it harder and harder as the engine continued to rev even higher. I began to smell the brakes burning as they tried to hold the car back. Fortunately I had the foresight to put the car in neutral. It continued to rev for about 5 seconds and then went down to normal. It has happened once. No warning lights went on. The dealer said that they contacted the detroit technical bureau and they suggested that maybe it was the floor mat, or my foot, etc, etc but claimed they had no other reports of this occurring. I don't have carpets as I opted for the rubber mats and they sit tight to the floor. And my foot was not stuck on the gas. I was conscious of the fact that my foot was on the brake and not the gas as I was trying to figure out what the heck was going on. They said they drove it and did computer checks and had no explanation. The service rep said the response from the technical bureau would be "insulting to me". The…
Tl* the contact owns a 2012 jeep cherokee. The contact stated that while at a stop light, he felt the vehicle accelerated independently. He keep his foot on the brake and turned off the vehicle and turned it back on and the vehicle reset. The vehicle was taken to the dealer for a diagnosis. The dealer stated they could not find a failure. The manufacturer was not contacted. The failure and the current mileage was 10,000.
Cold started vehicle. Waited for fast idle to subside (cool weather). Placed in drive and slowly accelerated into garage, appr 30 feet. Braked vehicle to full stop. Vehicle seemed to be under some level of power, more than idle speed with no acceleration by driver. Began to shift out of drive and once the shift lever was in the neutral slot, the engine rpms increased to about 4000 RPM. Engine was shut down in neutral to avoid shifting into park at high RPM. Second occurrence on 15nov2012, same situation. Contacted local dealer (bb - chrysler jeep) (16nov2012 0931), spoke with pm - service consultant who stated that there were no recalls or service bulletins on this vehicle for acceleration type problems. He recommended to bring in for inspection if it happens again. *tr

How far this goes
Complaints are voluntary, so 20 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 2012 Jeep Grand Cherokee?
Across 19 owner reports that included an odometer reading, half were filed by 50,000 miles. A quarter were filed before 15,000 miles and a quarter after 105,000 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 2012 Jeep Grand Cherokee?
20 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.
