Other engine problem on the 2014 Toyota Corolla
2 crashes 2 of the 12 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 engine problem gets reported
Owners of the 2014 Toyota Corolla report other engine problem at a median of 25,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 45,000 miles, from 10 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 11th most-reported problem on this model year.
The mileage distribution
The reported range runs from 900 miles at the tenth percentile to 70,000 miles at the ninetieth, a spread of 67,917 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.
70% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 883 miles | 7,295 miles | 24,589 miles | 44,250 miles | 68,800 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, 2 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 $300–$4,000 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.
The same failure on other years
The same failure is reported on 26 model years of this car. It shows up earliest on the 2004, at a median of 10,000 miles, and latest on the 2021 at 100,000 miles.
By volume the 2020 carries the most reports, with 85; the 2014 has 12. 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 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 my driveway at 1 mile per hour and I put my foot on the brake to stop my car and it wouldn't stop! The engine revved up and my car went through my fence into my backyard. I tried in vain to stop my car, I kept pressing down on my brake, (5 times) with no success. I finally put my automatic transmission into park and it finally came to a stop. I was extremely shaken up since I thought I was going to die! I checked my car for damages, I noticed that my passenger side view mirror was damaged and there was other damage under my car. My car is only 3 months old and has 950 miles on it. I have been driving for over 30 years and I have never encountered anything like this. This happened on november 27, 2014, thanksgiving day at 10:00 am. The weather conditions were cloudy with a temperature of 34 degrees. *tr
Pulled left into parking area, car accelerated very fast, went over 4-6" berm. I hit the brake, car stopped. Backed down off berm, didn't do damage. Took car to toyota, report done and an analysis. Determined "unintended acceleration...pedal misapplication" . Not convinced that's what happened especially after reading other similar complaints. Feel there is a defect in car, further investigation is needed. *tr

How far this goes

How common is other engine problem on the 2014 Toyota Corolla?
12 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.
