Headlight failure or clouding on the 2001 Hyundai Elantra

2 crashes 2 of the 6 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 headlight failure or clouding gets reported

There are 6 reports of headlight failure or clouding on the 2001 Hyundai Elantra, 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 22nd most-reported problem on this model year.

The whole distribution

Percentiles of the 3 odometer readings owners gave.
10th25thMedian 75th90th
— — 55,045 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 $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 2013, at a median of 5,000 miles, and latest on the 2011 at 165,000 miles.

By volume the 2019 carries the most reports, with 38; the 2001 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.

Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.

On friday, september 28, 2012 at approximately 9:30am I was pulling into a parking spot at the heb grocery store on i45 at 646 in league city, tx when the engine on my 2001 hyundai elantra revved and roared very loudly and surged into the pickup truck parked in the opposite spot. At the time I did not have my foot on either the gas pedal or brake. I stomped on the brake but nothing happened-it just kept revving and surging forward. I shoved the stick into park and luckily it stopped. My car was now in the space the pickup truck had been parked in, and the pickup truck was shoved out into the driving lane between parking sections. I am extremely thankful that no one was in the pickup or walking by or loading groceries nearby and no one was hurt. I was so frightened I was shaking and could barely dial 911 on my cell phone. The pickup had minor damage to its rear bumper, and my car had crushing damage to the front end (hood and bumper crumpled, grille cracked, 1 headlight broken) and a large puff of white smoke poured out briefly (no fire). The police case# is 12-4584 and the state farm insurance claim# is 53-195c-229. The car was…

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 2001 Hyundai Elantra?

Across 3 owner reports that included an odometer reading, half were filed by 55,000 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 headlight failure or clouding on the 2001 Hyundai Elantra?

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.
