Headlight failure or clouding on the 2014 Toyota Corolla
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 headlight failure or clouding gets reported
There are 6 reports of headlight failure or clouding on the 2014 Toyota Corolla, 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 88,000 miles. It is the 17th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 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
Putting it right typically runs $150–$1,800 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 11 model years of this car. It shows up earliest on the 2019, at a median of 5 miles, and latest on the 2000 at 160,000 miles.
By volume the 2001 carries the most reports, with 6; the 2014 has 6. 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 driving at night, with low beams on, oncoming traffic will flash their headlights. This has happened numerous times with some oncoming traffic turning on their high beams and leaving them on as they approach our car. I have checked to make sure that low beams are on when there is oncoming traffic. I have had the toyota dealer check the headlight adjustment twice. Their response is that the headlights are adjusted to spec. We are hesitant to drive the car at night because of the complaints we have received about the headlights.
Headlight is one assembly and cost so much to replace that's why when the bulbs gets burnt out owners will just wait until the other one gets burnt also because it is too expensive to replace the whole assembly not like other cars that you can replace the bulbs for less than $5.00 but with this car it is like $250 to replace a burnt headlight. People who drive this corolla's are taking their risk specially at night driving without sufficient lights because it is too expensive to replace. Please check on this, thanks.
Rear end collision hazard due to defective, poorly designed, automatic headlight systems. Almost got rear ended twice due to lack of tail lights, while in motion, driving! Toyota claims the 2014 corolla has auto headlights. While the switch is kept in "drl" daytime running light mode the car tricks you at night into thinking the auto headlight, side markers and taillights are on after starting the car, when they are not on. You start the car and the headlights, and dash gage lights come on but nothing else is lit. No tailights, no side lights. I am told by the dealer canadian versions of the corolla have true auto headlights and my car would have to be programmed to work as an auto system, after adding the dash sensor. I am requesting toyota do this to correct this safety hazard to avoid a rear end collision on this car. All of my cars the last 20 yrs had auto headlights and worked flawlessly except this toyota corolla. I even put a note on the dash to remind me to manually turn the light switch on, but it is not seen in the dark when starting the car. I do not know what else to do other than appeal to the NHTSA for a complete…

How far this goes
This page is kept out of search results because 6 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 6 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 headlight failure or clouding happen on the 2014 Toyota Corolla?
Across 3 owner reports that included an odometer reading, half were filed by 500 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 headlight failure or clouding on the 2014 Toyota Corolla?
6 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.
