Other body or interior problem on the 2005 Toyota 4RUNNER
3 crashes 1 injury 4 of the 107 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.
When other body or interior problem gets reported
Owners of the 2005 Toyota 4RUNNER report other body or interior problem at a median of 130,000 miles. A quarter of the reports come in before 85,000 miles and a quarter after 165,000 miles, from 67 reports that carried an odometer reading.
A part like this is normally expected to survive 88,000 miles. It is the 1st most-reported problem on this model year.
The mileage distribution
The reported range runs from 47,500 miles at the tenth percentile to 190,000 miles at the ninetieth, a spread of 141,286 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.
3% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 47,714 miles | 85,000 miles | 129,000 miles | 165,500 miles | 189,000 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, 3 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.
Putting it right typically runs $200–$2,000 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 21 model years of this car. It shows up earliest on the 2009, at a median of 30 miles, and latest on the 1996 at 185,000 miles.
By volume the 2004 carries the most reports, with 185; the 2005 has 107. 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.
Driver's seat on new 2005 toyota sr5 4runner rocks and shifts back and forth while driving. Dealer has already replaced seat linkage and frame assembly and seat movement has gradually returned in a very short time period. Dealership tried to call it a normal condition prior to replacing saying that all seats in 4runner's on the lot were loose from the factory. As vehicle is driven and weight of driver shifts back and forth from stops and starts, linkage in seat weakens and works loose. Very poor design. Condition is very dangerous and safety should be toyota's #1 concern but obviously not yet. *jb
2005 toyota 4 runner sr 5 spare tire bracket/ holder severely prematurely rusted. Dealer unable to remove spare tire. Lubricant applied by dealer to no avail. Bracket/holder defect makes spare tire unavailable for use and can lead to bracket/holder failure. Dealer unable to remedy leaving vehicle owner with no spare and potential for catastrophic event while vehicle in use. *tr
My 2005 toyota 4 runner has become so rusted along the frame and undercarriage that the vehicle is unsafe to drive. I have used the vehicle for highway and normal road use. I bought the vehicle brand new and have never towed anything. My tundra was purchased at exactly the same time and has been driven under the same conditions. It has no rust problems. There seems to be a problem with the undercoating of some of toyota's vehicles. Any information you have would be greatly appreciated. *tr

How far this goes
Complaints are voluntary, so 107 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 body or interior problem happen on the 2005 Toyota 4RUNNER?
Across 67 owner reports that included an odometer reading, half were filed by 130,000 miles. A quarter were filed before 85,000 miles and a quarter after 165,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other body or interior problem on the 2005 Toyota 4RUNNER?
107 reports have been filed with NHTSA, about 1.3 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.
