Why it's a good car

The 2015 4Runner is part of the fifth generation (2010–present) and one of the last of the truly rugged, body-on-frame SUVs. It uses a proven 4.0-liter V6 with a conventional five-speed automatic — no CVT, no turbo — and a timing chain, and it is genuinely built to last, with excellent off-road ability and class-leading resale value. There is no systemic drivetrain failure to worry about; the trade-off is truck-like fuel economy and ride.

Does it have a timing belt or a timing chain?

A timing chain, so there is no timing-belt interval or scheduled timing service to budget for.

What actually goes wrong

Genuinely little for a vehicle this capable:

Open recalls — check the VIN, it's free

Confirm the Denso fuel-pump recall (a failing pump that can stall the engine) and any other campaigns on the specific vehicle — recalls are VIN-specific and cannot be assumed from the model year. Look up any 2015 4Runner's open recalls free by VIN at the U.S. National Highway Traffic Safety Administration (NHTSA); a Toyota dealer completes any open recall at no charge.

What a history report tells you — and what it doesn't

On a car like this, the individual car's history is most of the decision. A history report is a record of what got reported — title brands, reported accidents and damage, odometer readings over time, and service records where they exist. That is what separates a clean, maintained example from a salvage-title or flood car wearing the same badge.

What a history report is not is a forecast, and an absence of records is not proof of a clean past — plenty happens to a car that never gets reported. That is why the honest answer is always the pair: the documented history and an in-person inspection by a mechanic you trust, on the specific car.
