Unclassified problem on the 2016 Toyota Tundra
Only 10 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 2016 Toyota Tundra report unclassified problem at a median of 15,000 miles. A quarter of the reports come in before 5,000 miles and a quarter after 30,000 miles, from 10 reports that carried an odometer reading.
It is the 34th most-reported problem on this model year.
The mileage distribution
The reported range runs from 5,000 miles at the tenth percentile to 45,000 miles at the ninetieth, a spread of 40,598 miles across the middle 80% of reports.
Reports bunched into a band this tight usually mean the component has a life of its own: it goes at roughly the same mileage regardless of who owns it.
80% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 2,702 miles | 6,500 miles | 16,000 miles | 27,875 miles | 43,300 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.
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 2016 has 15. 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.
Factory integrated brake controller does not work efficiently. With the ibc gain up to 10, the trailer brakes are not activated enough to slow the vehicle in a normal or emergency situation. The manual override slide bar barely engages the trailer brakes, it will not lock the trailer brakes as designed. Vehicle brakes begin to get to hot to slow both the truck and trailer coming down hills, extremely dangerous!
Re: integrated break controller I wanted to express a serious safety concern I have with an item that now ships with the 2016 toyota 5.7l tundra's - the built in / integrated break controller for use when pulling trailers/campers/etc. It seems that regardless of the power setting, no noticeable power is supplied to the trailer brakes, even at it's highest setting. It feels like the trailer/camper is pushing the truck, which can be a serious issue when stopping. This would happen every time I would tow and I was always very worried about causing an accident if I needed to stop quickly or if the road conditions were not idea. I've never felt this with other break controllers. It's my understanding toyota has not acknowledged this as being an issue yet. After talking to many other tundra owners everyone has the same issue, I've not talked to anyone that has a working integrated break controller in their 2016. I've taken out my integrated break controller that came in my 2016 toyota tundra and replaced it with an after market brake controller out so I can property brake with my camper attached. For now my issue is resolved, however, I…
The integrated elecric brake controller included in my platinum edition options for towing a trailer does not work. According to dealer, there is no fix from toyota although they are aware of the issue.

How far this goes
This page is kept out of search results because 15 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 15 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 2016 Toyota Tundra?
Across 10 owner reports that included an odometer reading, half were filed by 15,000 miles. A quarter were filed before 5,000 miles and a quarter after 30,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is unclassified problem on the 2016 Toyota Tundra?
15 reports have been filed with NHTSA, about 0.4 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.
