Unclassified problem on the 1999 Toyota Camry
43 crashes 29 injuries 72 of the 60 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 13 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 unclassified problem gets reported
Owners of the 1999 Toyota Camry report unclassified problem at a median of 100,000 miles. A quarter of the reports come in before 70,000 miles and a quarter after 155,000 miles, from 13 reports that carried an odometer reading.
It is the 61st most-reported problem on this model year.
The mileage distribution
The reported range runs from 65,000 miles at the tenth percentile to 160,000 miles at the ninetieth, a spread of 96,262 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.
0% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 62,800 miles | 70,000 miles | 100,000 miles | 153,000 miles | 159,062 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, 43 a crash and 29 an injury 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.
The same failure on other years
The same failure is reported on 28 model years of this car. It shows up earliest on the 2020, at a median of 5,000 miles, and latest on the 1998 at 125,000 miles.
By volume the 2007 carries the most reports, with 281; the 1999 has 60. 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.
(1) the vehicle I was driving in was proceeding to make a left turn on a green traffic signal when other vehicle failed to obey red traffic signal thus striking my vehicle between the driver's side front and driver's side rear doors ("b" pillar). *ak (2) side airbag did not inflate contributing to more serious injuries sustained. (3) vehicle was totaled by insurance company. Could not find contact information on manufacturer to make notifcation of defect.
While driving at 45 MPH, another motorist pulled out in front of the consumer. The consumer t-boned the other motorist. The air bags failed to deploy upon impact. The consumer sustained a sternum and the passenger sustained severe back and neck injuries. *jb
After being struck on the side by a vehicle traveling approximately 45 MPH the side impact air bag came out to the size of a small balloon, it did not deploy to full size. The vehicle was a total loss. *jb.

How far this goes
This page is kept out of search results because 60 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 60 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 unclassified problem happen on the 1999 Toyota Camry?
Across 13 owner reports that included an odometer reading, half were filed by 100,000 miles. A quarter were filed before 70,000 miles and a quarter after 155,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is unclassified problem on the 1999 Toyota Camry?
60 reports have been filed with NHTSA, about 4.5 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.
