Other speed control problem on the 2003 Acura MDX
1 crash 1 of the 5 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.
Only 5 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When other speed control problem gets reported
There are 5 reports of other speed control problem on the 2003 Acura MDX, 5 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
A part like this is normally expected to survive 78,000 miles. It is the 13th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 22,500 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, 1 a crash is 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 15 model years of this car. It shows up earliest on the 2018, at a median of 5,000 miles, and latest on the 2001 at 145,000 miles.
By volume the 2017 carries the most reports, with 18; the 2003 has 5. 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.
While waiting at a stop light and without warning vehicle surged forward while driver's foot was on the brake pedal. *ak failure also occurred by a stop sign at an elementary school. The problem was an air intake leak, which began approx. Three weeks after consumer purchased the vehicle and still exist today. The engine died and the check engine light illuminated. The consumer made several attempts to have the vehicle repaired, but to no avail. The consumer would like her monies reimbursed or a brand new mdx with the same options and color of her choice. *ph *nlm
As I was backing-up in parking lot, the car suddenly accelerated. After traveling ~ 20' at an accelerated pace, the rear of the car hit a concrete ballard. Upon impact the car jumped into a forward gear, accelerated forward and hit a parked car. If not for the parked car, our acura mdx would have plowed into a store front. *jb
While traveling at around the speed limit on a busy freeway the vehicle suddenly started coasting without any warning. Stepping on the gas caused the engine to rev but no acceleration, which made it extremely dangerous to try to pull the vehicle to the shoulder with the right lane heavily occupied by 18 wheeler trucks that are long and respond slowly. Any speed you loose, particularly after applying some brake to move from one lane to another, cannot be regained to safely maneuver with flow of the traffic and make the subsequent lane change even more dangerous. After towing to an acura dealer it was diagnosed with a failed transmission and costs $6,100 to replace with a rebuilt transmission. Although the vehicle is beyond its warranty period, it is nonetheless disappointing to have an acura fail in this fashion considering that there are many lower cost vehicles that easily last beyond 100,000 miles without transmission issues. The vehicle certainly met its warranty requirements, but it is really the sudden nature and crash risk of this failure that is a bigger concern. I later learned from 3 co-workers that had similar…

How far this goes
This page is kept out of search results because 5 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 5 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 2003 Acura MDX?
Across 5 owner reports that included an odometer reading, half were filed by 25,000 miles. A quarter were filed before — and a quarter after —. 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 2003 Acura MDX?
5 reports have been filed with NHTSA, about 0.0 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.
