Other electrical problem on the 2017 Toyota Corolla
1 crash 1 fire 2 of the 15 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 electrical problem gets reported
Owners of the 2017 Toyota Corolla report other electrical problem at a median of 15,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 40,000 miles, from 8 reports that carried an odometer reading.
A part like this is normally expected to survive 85,000 miles. It is the 3rd most-reported problem on this model year.
The mileage distribution
The reported range runs from 600 miles at the tenth percentile to 110,000 miles at the ninetieth, a spread of 111,539 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.
63% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 561 miles | 6,816 miles | 16,596 miles | 39,500 miles | 112,100 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 and 1 a fire 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.
The same failure on other years
The same failure is reported on 24 model years of this car. It shows up earliest on the 2020, at a median of 5,000 miles, and latest on the 2021 at 130,000 miles.
By volume the 2010 carries the most reports, with 51; the 2017 has 15. 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.
Tl* the contact owns a 2017 toyota corolla. While driving 40 MPH, the crash avoidance sensor malfunctioned. The contact stated that the sensor did not apply the brakes or detect that the vehicle was too close to another vehicle. The dealer repaired the vehicle, but the failure recurred. The dealer refreshed the sensor software in the vehicle, but this did not correct the failure. The manufacturer was not made aware of the failure. The failure mileage was 800.
While coming to a stop at a stoplight, a car come out if no where. I tried to slam on the brake to come to a stop faster but the breaking system did not react to the pedal being pressed down. I was met with a stiff pedal and I could feel the brakes pushing back which caused me to hit another car that had already entered into an intersection.

In addition, the rear passenger side seat adjustment latch fractured. Hendrick toyota scion wilmington (5640 market st, wilmington, nc) was notified, but the failures could not be duplicated. Furthermore, the contact had to replace the vehicle battery shortly after purchasing the vehicle. Kendall toyota (10943 s dixie hwy, miami, fl) was also made aware of the failures, but the vehicle was not repaired. The manufacturer was not made aware of the failures. The failure mileage was approximately 20,000.

How far this goes
Complaints are voluntary, so 15 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 electrical problem happen on the 2017 Toyota Corolla?
Across 8 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 40,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other electrical problem on the 2017 Toyota Corolla?
15 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.
