Other speed control problem on the 2014 Toyota Corolla
9 crashes 2 injuries 11 of the 21 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 2014 Toyota Corolla report other speed control problem at a median of 15,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 30,000 miles, from 16 reports that carried an odometer reading.
A part like this is normally expected to survive 78,000 miles. It is the 4th most-reported problem on this model year.
The mileage distribution
The reported range runs from 200 miles at the tenth percentile to 55,000 miles at the ninetieth, a spread of 55,198 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.
75% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 191 miles | 3,840 miles | 15,731 miles | 28,175 miles | 55,389 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, 9 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 23 model years of this car. It shows up earliest on the 2010, at a median of 6,000 miles, and latest on the 2000 at 130,000 miles.
By volume the 2009 carries the most reports, with 163; the 2014 has 21. 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

I was driving my corolla s plus 2014 on el camino real, san mateo, ca southbound just past hillsdale blvd, when the engine became very noisy. I looked at the instrument panel and found the followings data: 1) RPM meter - 3500 2) speedometer - 30mph 3) lcd display - eco bar gone the car behaved the same even when I took my foot completely off the accelerator pedal. Transmission defect and/or computer malfunction? Luckily I was able to pull my car to the roadside and braked to a stop. I turned the engine off. After 2-3 minutes, I started the engine and all returned to normal. The exact same happening occurred to me just 2 days later on march 19, 2014. It could be very scary if the engine suddenly revs up and the car speeds up at the same time. I wonder if other owners of 2014 corolla have similar experiences. If so, this is something that has to be investigated. *tr
I was pulling into a parking space & slowing down. I turned left into the space and, of course, had my foot on the brake and my car suddenly accelerated on it's own. I kept pushing on the brake but it kept going. The higher than usual curb at the shopping center, I suppose, is what stopped the car, though my foot repeatedly kept pushing the brake. I tried to drive it home but it was not working. We had it towed to toyota in rockwall. They had someone look at it. The person that looked at it called my home to get my story but asked my husband what took place. I didn't get the message till the next day. When I was getting ready to call him back, my husband told me that he called and said he did not need to talk to me. How can you legitimately tell me what I say happened did not happen when you haven't even talked to me. I was the only one in the car, not my husband. They checked out the "black box" I suppose and sent me a very nice letter basically telling me what I told my husband happened, did not happen. I do not lie. I was there and I know what happened. I was very disappointed in the way that this was handled. I felt like how…

How far this goes
Complaints are voluntary, so 21 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 2014 Toyota Corolla?
Across 16 owner reports that included an odometer reading, half were filed by 15,000 miles. A quarter were filed before 5,000 miles and a quarter after 30,000 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 2014 Toyota Corolla?
21 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.
