Other speed control problem on the 2010 Hyundai Tucson
1 crash 1 of the 3 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 3 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 3 reports of other speed control problem on the 2010 Hyundai Tucson, 3 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 9th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 30,000 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 18 model years of this car. It shows up earliest on the 2022, at a median of 5,000 miles, and latest on the 2013 at 100,000 miles.
By volume the 2016 carries the most reports, with 76; the 2010 has 3. 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.
My problem with this tucson is in regards of "sudden unintended acceleration". It sporadically, on an almost daily basis we experience "sua" followed by immediately loses power and acceleration every time it's driven. Ex: driving on the freeway doing 70mph, it will lunge and the tachometer will race and suddenly loses power down to 35mph. Then has a lag accelerating afterwards. This is consistent through out the day since I commute a lot. Other issues, when engine on idle it feels like it's about to stall. We have taken this to the dealership 3 times and from their diagnosis, they don't see the problem. There is definitely a malfunction in the transmission and doing research I've found these issues with numerous tucson owners. We are concerned with our safety as we now have had a couple of close calls on the freeway. We bought this vehicle for safety and now are starting to question our safety due to this issue. *tr
On three separate occasions this vehicle experienced unintentional acceleration while either braking or slowly attempting to park. During each incident the auto accelerated at high speed while my foot was on the brake and I was unable to stop the auto from proceeding forward even with both feet heavily applied to the brakes. Each time I was luckily able to maneuver to avoid hitting any pedestrians in my path and fortunately there were no human injuries during any of these occasions. However, two of the incidents did result in a collision. The first was a minor rear end crash resulting from the inability to stop the auto when it unintentionally accelerated while braking for a red light. The last incident resulted in expensive auto damage when the auto unintentionally accelerated while slowly pulling into a parking spot along the street and causing the auto to jump the curb. To avoid hitting pedestrians walking on the sidewalk or crashing into a storefront, I was forced to collide into a telephone pole to stop the auto resulting in thousands of dollars of front end damage. *tr

How far this goes
This page is kept out of search results because 3 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 3 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 2010 Hyundai Tucson?
Across 3 owner reports that included an odometer reading, half were filed by 30,000 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 2010 Hyundai Tucson?
3 reports have been filed with NHTSA, about 0.1 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.
