Other suspension problem on the 2015 Toyota 4RUNNER
Only 5 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 suspension problem gets reported
There are 8 reports of other suspension problem on the 2015 Toyota 4RUNNER, 5 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 100,000 miles. It is the 4th most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 38,977 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 $350–$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 18 model years of this car. It shows up earliest on the 2021, at a median of 400 miles, and latest on the 1996 at 185,000 miles.
By volume the 2003 carries the most reports, with 59; the 2015 has 8. 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.
I have a new 4runner that I was not pleased with how it was handling. I took it into an independent wheel alignment shop to get an objective opinion. The results are included in the attached document. 10 out of 14 of the settings were out of specification. I paid to have these items fixed. My car now tracks better. Corners better and has a more stable ride. These settings were so bad I now realize that I was in car that was not as safe as it should have been. I have submitted this attachment to toyota usa and the dealer and the only response has been they will file my complaint. I am amazed that toyota did not consider this a manufacturing defect that they should remedy as part of a new car sale.
Tl* the contact owns a 2015 toyota 4runner. While driving 65 MPH, the vehicle vibrated and the steering wheel shook and made a chattering noise. The tires were replaced because the contact thought they were the cause of the failure; however, the failure continued. The dealer was notified. The vehicle was not diagnosed or repaired. The failure mileage was 27,000.
Has a steering wheel shimmy between 60-70 MPH, causing premature wear on tires. Just bought 80k mile warranty tires are they are completely bald at 20k miles even after being rotated every 5k miles, balances, and alignments. Unable to keep vehicle aligned and in balance no matter how soon I have it done after just having it done (once in august and then again immediately in september. Body shop advising that the weld on the rear axle is incorrect causing this issue. Attempted to speak with toyota warsaw, they aren't getting back to me as they said they would, called corporate 800 number and spoke to a rude female who was unwilling to help me. Was told that I had already been driving on unsafe tread, that what would another week hurt? Can't buy new tires until issue is fixed because the tires will just prematurely wear again.

How far this goes
This page is kept out of search results because 8 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 8 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 suspension problem happen on the 2015 Toyota 4RUNNER?
Across 5 owner reports that included an odometer reading, half were filed by 40,000 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 suspension problem on the 2015 Toyota 4RUNNER?
8 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.
