Headlight failure or clouding on the 2007 Lexus Rx350
Only 4 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 2007 Lexus Rx350, 4 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 9th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 50,150 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, every year of the Lexus Rx350
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.
Drivers side headlamp lens develops condensation on the inside of the lens. The amount of condensation is increasing daily and cannot be dried out. This adversely affects the refraction of the headlamp beam which is both dangerous for the driver and oncoming traffic.
I went to for routine maintenance and they told me I needed some bulbs replaced. I agreed to pay for the bulb replacement. About 2 weeks later, I noticed condensation in the headlight. I went back to and indicated that there had not been a problem with my headlight until after they replaced the bulb. They stated they did not cause this and that "this condensation problem just sometimes happens with the rx's. Water leaks into the headlight assembly". Since it appears that lexus knows this, they should fix it or have a recall. Stated that it would be "very expensive" to have the light fixed. I was thoroughly annoyed with them, (especially since I believe that they did indeed cause the issue), so I instead went to ). Told me that my car was out of warranty, so it would cost $2,200 to fix the light. What?! I asked why it was going to be so ridiculously expensive. They stated because they have to take the entire light housing out and will need to remove part of the bumper to do this and replace some kind of computer chip. Now my light is almost burned out from the moisture, so I have no choice but to eventually pay and get it replaced…

The manufacturer was notified and stated that they had to make a decision about repairing the vehicle again. The failure mileage was 50,000. The VIN was unavailable.

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 2007 Lexus Rx350?
Across 4 owner reports that included an odometer reading, half were filed by 50,000 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 2007 Lexus Rx350?
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.
