What this can and cannot tell you: these are complaints owners chose to file, not a failure rate. Popular models accumulate more of them simply by being common. How this is built.
Owners filed 1,759 complaints with NHTSA about the 1996–2002 Toyota 4Runner, and 1,428 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.
87% of failures occur beyond 100,000 miles — a wear pattern. The car generally reaches substantial mileage before trouble starts.
The most-reported areas are body structure (41.3% of complaints, typically around 156,000 miles), the suspension (20.6% of complaints, typically around 170,000 miles), problems owners could not categorise (10.4% of complaints, typically around 170,000 miles).

Which systems, and when
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 155,000 miles; the figures below show which parts of the car run ahead of that and which run behind.
Body structure accounts for 41.3% of complaints (727 reports, 593 of them with a mileage figure), with a median of 156,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 126,777 and 195,000 miles.
A single system taking 41.3% 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 20.6% of complaints (362 reports, 299 of them with a mileage figure), with a median of 170,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 133,000 and 205,000 miles.
Problems owners could not categorise accounts for 10.4% of complaints (183 reports, 132 of them with a mileage figure), with a median of 170,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 136,541 and 215,000 miles.
The transmission and driveline accounts for 7.2% of complaints (127 reports, 116 of them with a mileage figure), with a median of 138,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 112,000 and 170,000 miles.
The steering accounts for 3.8% of complaints (67 reports, 54 of them with a mileage figure), with a median of 160,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 120,000 and 200,000 miles.
Throttle and speed control accounts for 2.0% of complaints (35 reports, 26 of them with a mileage figure), with a median of 116,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 90,000 and 160,000 miles.
Differences between model years
Within this generation, complaint volume is not constant across model years. The 2000 model year drew the most — 520 complaints — while 1996 drew the fewest at 92. The median year sits at 206.
That makes 2000 an outlier: roughly 2.5 times the median year of this generation. A single year standing that far apart usually reflects either a first-year issue that was later corrected, or a component change introduced for that year. Anyone shopping this generation has a straightforward reason to prefer a different year, all else being equal.
Recalls and what they cover
No recall campaigns covering this generation appear in NHTSA's post-2010 recall file. That is not the same as an absence of problems — recalls address safety defects specifically, and many of the complaints above concern faults that are expensive or annoying without meeting that threshold.
Reported severity
Of the 1,759 complaints filed against this generation, 99 reported a crash; 15 reported a fire; 77 reported an injury; 6 reported a fatality. Crash-involved reports represent 5.6% of the total.
These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.
What this means if you are buying one
For a buyer, a late-failure pattern shifts the question from whether to when. 87% of reported failures occur beyond 100,000 miles, so an example approaching that figure is approaching the range where other owners started reporting problems. The middle half of all failures falls between 120,000 and 197,000 miles.
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 156,000, 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.
Documented problems
Suspension — Front Lower Ball Joint Recall covers 2001–2002; failures reported across 1996–2002
Lower ball joint wear and separation, which can allow the suspension to collapse and the wheel to fold under at speed. Toyota recalled 2001-2002 4Runners for the defect; owners note the same lower ball joint part number was used from 1996 through 2002 and report failures on earlier, non-recalled vehicles.
Structure — Frame Corrosion 1996–2002 (salt–belt vehicles)
Severe frame rust, particularly at the rear of the frame rails and crossmembers, in salt-exposed regions. NHTSA received reports of steering and suspension components separating from a rusted-through frame.

What owners reported
Hi, the frame is extremely rusted. It had a small tear on a weld. Now it has a large tear in the frame. It appears that it is rusting at all the weld points at a accelerated rate and or the frame itself is not thick enough. I have read of hundreds of others that own this car and the frame has rusted through. I…

I contacted Toyota about a recall on my 1996 limited 4Runner. There was a rear coil spring recall. I took my 4Runner to the local Toyota dealership to have the springs replaced and was informed by their mechanic that the frame was so rusty with holes that they would not work on it and it was unsafe to drive. They…
