Each tile shows the median mileage at which that model year’s failures were reported. The 2004 reports latest and the 2008 earliest, but part of that gap is age: the 2004 has had 4 more years on the road to accumulate mileage. 1 of these years carries fewer than 30 reports with an odometer reading and shows no median at all, rather than one computed from a handful.

Owners filed 2,451 complaints with NHTSA about the 2003–2009 Toyota 4Runner; body structure leads with 40% of them, and half of the 1,711 that record an odometer reading came by 100,000 miles. A count like this can’t rate reliability on its own: NHTSA records what owners chose to report, not how many of each car were sold.
Failures are spread across the mileage range, with the middle half between 48,000 and 150,000 miles.

How many miles does a 2003–2009 Toyota 4Runner last?
Complaint records can’t measure how long a car lasts; they show when reported failures happened. On the 2003–2009 Toyota 4Runner, half of the 1,711 complaints that record an odometer reading were filed by 100,000 miles and 90% by 186,000 miles.
444 reports came in past 150,000 miles and 119 past 200,000 — each one proof that a 4Runner reached that mileage, not that it failed there.

System by system, in words
Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 100,000 miles; the figures below show which parts of the car run ahead of that and which run behind.
Body structure accounts for 40.0% of complaints (981 reports, 652 of them with a mileage figure), with a median of 130,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 95,000 and 165,000 miles.
A single system taking 40.0% of all complaints is a concentration worth noting. It means that for this generation, most of what owners reported came back to one area of the car rather than being distributed across many small faults.
The suspension accounts for 16.2% of complaints (396 reports, 254 of them with a mileage figure), with a median of 132,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 87,000 and 166,000 miles.
Problems owners could not categorise accounts for 16.0% of complaints (393 reports, 231 of them with a mileage figure), with a median of 139,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 103,000 and 165,000 miles.
The transmission and driveline accounts for 7.3% of complaints (178 reports, 148 of them with a mileage figure), and it fails early — a median of 38,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 8,000 and 103,000 miles.
The brakes account for 6.7% of complaints (163 reports, 129 of them with a mileage figure), with a median of 117,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 86,000 and 160,000 miles.
Throttle and speed control accounts for 6.0% of complaints (147 reports, 120 of them with a mileage figure), and it fails early — a median of 52,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 21,000 and 90,000 miles.
Known problems with the 2003–2009 4Runner
Structure — Frame Corrosion 2003–2009
Severe frame corrosion in salt-exposed regions that can compromise structural integrity. Toyota ran inspection campaigns for early 4th-generation vehicles and offered frame replacement or vehicle buyback for qualifying trucks.
Before you buy a 2003–2009 4Runner: the 3-minute check
Generated from 1,711 mileage-tagged complaints, 9 recall campaigns, 1 documented problem area. Print this page — the checklist survives print.
- Run the VIN at nhtsa.gov/recalls. 9 campaigns cover this generation; an open recall is a free repair you can make the seller's problem.
- Ask for engine and its cooling system repair records. Reports on this area come at a median of 1,500 miles — on any car this age it already happened or never will; the question is whether it was fixed under warranty.
- Check structure — frame corrosion on 2003–2009 (salt–belt vehicles; early years most affected) cars. Severe frame corrosion in salt-exposed regions that can compromise structural integrity. Toyota ran inspection campaigns for early 4th-generation vehicles and offered frame replacement or vehicle buyback for qualifying…
- Complaint reports are not spread evenly across model years here — see the by-model-year table below before you settle on a year.
- End with a pre-purchase inspection of this car. Aggregate data describes the population; the example in front of you has its own history.
For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 48,000 and 150,000 miles, with a median of 100,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.
On inspection, body structure and the suspension are where this generation's reports concentrate, so those are the areas worth a specific look. Body structure in particular shows a median failure mileage of 130,000, which gives a concrete number to compare against the odometer of any car you are considering.
None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.

2003–2009 Toyota 4Runner recalls (9)
NHTSA records 9 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.
The campaigns cluster around seats (3), equipment (2), the airbag system (1). Several campaigns against one area can mean a remedy that did not hold, or separate defects in parts filed under the same heading; the summaries below name each defect.
Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.

- Fatality reports

These flags are self-reported by complainants and unverified by NHTSA; one report can carry several flags, so the counts overlap and do not sum to a total. They are not adjusted for how many of these vehicles are on the road. No chart is drawn here on purpose: overlapping counts spanning very different magnitudes cannot be honestly encoded as lengths.
4Runner problems by model year
The 2003 drew the most complaints of this generation, 695, most of them about body structure, and the 2009 the fewest, 22. A typical year drew about 381.
The first year of the generation, 2003, drew more complaints than a typical year. A count like this follows how many cars of each year were sold and how long they have been on the road as much as how often they failed, so it is not by itself evidence of a worse year; what each year's reports name, in its card and row, is the useful part.
