Unclassified problem on the 2011 Toyota Tundra
2 crashes 1 injury 3 of the 17 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 11 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 2011 Toyota Tundra report unclassified problem at a median of 70,000 miles. A quarter of the reports come in before 45,000 miles and a quarter after 90,000 miles, from 11 reports that carried an odometer reading.
It is the 37th most-reported problem on this model year.
The mileage distribution
The reported range runs from 20,000 miles at the tenth percentile to 105,000 miles at the ninetieth, a spread of 82,843 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.
18% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 20,000 miles | 43,368 miles | 68,215 miles | 89,630 miles | 102,843 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 and 1 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 22 model years of this car. It shows up earliest on the 2018, at a median of 2,100 miles, and latest on the 2001 at 165,000 miles.
By volume the 2006 carries the most reports, with 118; the 2011 has 17. 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 down the interstate the check engine light and traction control light came on and the vehicle loss engine power and began to slow. After I could not accelerate and it became unsafe for me to drive without the possibility of an accident occurring and possible injury or death, I pulled over and had to limp vehicle back home. Toyota refuses to fix it saying it only offers replacement on the 2007-2010 toyota vehicles. The defective part number is the same on my 2011 as all the other toyotas but they stopped covering it in the later models. The dealer said they had to repair so many that at one time there was a 60 day backlog on parts. This is ridiculus and toyota is risking the lives of those that drive their product. I will have to pay to fix this on top of what I paid for the vehicle. I will warn everyone I can reach to never buy a toyota. Toyota has become a company of subpar customer support and deserves every class action suit they get filed against them. Whoever begins one on these failed air injection pumps count me in for the refund and the mental anguish of trying to get toyota to stand behind their product!!!…
I bought this truck new, the door locks have never worked right.I have had the relay or motors that work the door locks fixed 6 or 7 times, and have one going bad now on the driver side front door. This will be the 3rd time for this door.they say they know they have a problem with these but will not do a recall on them.this is not the only model having trouble with this.I cant lock my truck some times this is a problem . Will any thing be done are will they keep putting faulty parts on my truck till something shorts out!!!!!!!!!!!
The air induction pump (aip) on 2007-2010 are covered by an extended warranty up to 10 years due to failures. My 2011 tundra, manufactured in 2010 has the exact same failure and the part is the exact same part that is being replaced on 2010's but it will costs me $2345.00 to have it repaired. Toyota knows it has a defective (aip) but refuses to cover the 2011's until enough consumers complain.

How far this goes
This page is kept out of search results because 17 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 17 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 2011 Toyota Tundra?
Across 11 owner reports that included an odometer reading, half were filed by 70,000 miles. A quarter were filed before 45,000 miles and a quarter after 90,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is unclassified problem on the 2011 Toyota Tundra?
17 reports have been filed with NHTSA, about 0.3 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.
