Other driver assistance problem on the 2012 Toyota Tundra
Only 6 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 other driver assistance problem gets reported
There are 6 reports of other driver assistance problem on the 2012 Toyota Tundra, 6 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 45,000 miles. It is the 8th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 79,893 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 $250–$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 10 model years of this car. It shows up earliest on the 2018, at a median of 2,400 miles, and latest on the 2008 at 95,000 miles.
By volume the 2022 carries the most reports, with 18; the 2012 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.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
My 2012 toyota tundra is equipped with toyota's vehicle stability control (vsc). One of the features of the vsc is when the computer perceives a loss of traction, the computer (without the driver's consent) attempts to correct the loss of traction by braking and/or engaging one or both of the front tires. In november of 2016, the vsc on my tundra (with only 43k miles) began to fail and instead of becoming inoperable and doing nothing, the vsc attempts to engage the front tire(s) during routine turning movements. This causes a jerking sensation in the steering wheel and the vehicle pulls sharply to one-side. This could cause a loss of control. The vehicle has been to the dealer three times and I have spent nearly $2,800 trying to correct the problem. To date, toyota has been unable to correct the problem or disable the feature. It is my opinion the vsc system in the 2012 tundra is unsafe. This is not only based on the fact I am the owner of a defective tundra, prior to retiring in november 2015; I worked for the california highway patrol for more than 27 years as an officer and sergeant. I investigated numerous traffic collisions…
Tl* the contact owns a 2012 toyota tundra. The contact stated that the vehicle slowly accelerated from a stop sign when the accelerator pedal was depressed. In addition, the stability traction control warning indicator illuminated. The failure recurred on numerous occasions. The vehicle was taken to an independent mechanic where it was diagnosed that the air injection failed and needed to be replaced. The vehicle was not repaired due to the repair fees. The vehicle was not taken to a dealer. The manufacturer was notified of the failure and opened case number: [xxx]. The approximate failure mileage was 77,023. *tt information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tt
I see several other complaints here with my exact problem. The secondary air injection system relay and secondary air injection system switching valve. Obd ii codes p0418 and p2442. My experience is the same as other complaints in that my truck is now permanently in limp mode and cannot be driven due to these known defective parts. On pre-2012 model tundras toyota has extended the repair warranty to 10 years/150,000 miles as this is a widespread problem. For some reason they will not include later year model trucks like my 2012 4.6 liter. This is a safety issue as the truck slowed severely in traffic and will not accelerate or go up any hill. Cars behind me in traffic had to swerve around me. I was stuck dead at the bottom of a hill as these chronically failing parts shut down the vehicle's power. Toyota customer care has denied my attempt to seek compensation or repair of these parts that they know are defective. The fix needs to be extended to all year model and engine size tundras as these defective parts exist on models past 2011. A side note, somehow these defects are reported to be affecting the vehicle skid control as that…

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 other driver assistance problem happen on the 2012 Toyota Tundra?
Across 6 owner reports that included an odometer reading, half were filed by 80,000 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 other driver assistance problem on the 2012 Toyota Tundra?
6 reports have been filed with NHTSA, about 7.8 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.
