Reliability report · 2018 Toyota 4Runner · Updated July 2026 · ~$3,450/yr fuel · what it costs to keep →

A durable, low-drama 4Runner whose one real safety item is the fuel-pump recall — verify it's done, then enjoy a truck built to run past 250,000 miles.

The 2018 is a mature fifth-generation 4Runner with the proven 4.0-liter 1GR-FE V6 and A750 five-speed automatic. There is no expensive drivetrain failure pattern; independent mechanics are unanimous that this powertrain routinely goes 250,000-plus miles on basic maintenance, and the complaint file reflects that with a modest 57 entries.

The one genuine safety item is recall 20V-682: the low-pressure fuel pump can fail and stall the engine at speed. The fix is a free improved pump — many 2018 complaints are actually people frustrated by parts-delay waits during the recall rollout, not new failures. Verify it's completed by VIN. Beyond that, the usual 4Runner homework applies: soft-brake-pedal check, rodent-wiring inspection, and the salt-belt frame-rust check.

Canary status

Chirping

What that means: 57 federal complaints and five recalls. The one that matters is 20V-682, the low-pressure fuel-pump recall that can stall the engine while driving — this is the first 4Runner year in that population. The other four recalls are regional-distributor accessory and label items. Underneath, the 4.0-liter V6 and five-speed automatic remain the bulletproof pairing that defines this SUV.

Low-pressure fuel-pump recall — 20V-682

major

The one recall with real safety weight on this year. The low-pressure fuel pump inside the tank can fail, and when it does the engine can stall while driving — a stall-in-traffic risk. It covers 2018–2019 4Runners as part of a wide Toyota/Lexus campaign (an expansion of 20V-012). The remedy is a free improved pump. A large share of the 2018 complaint file is owners reporting the recall was open with parts unavailable, rather than fresh pump failures — but a stall is serious, so confirm by VIN that the pump was actually replaced.

Soft brake pedal and brake-feelmoderate

As across the generation, some owners report the brake pedal going soft or sinking, and mechanics separately note the 4Runner's brakes feel soft and nose-dive by design. Real master-cylinder and ABS-actuator failures do occur at low frequency, and the front calipers and slide pins seize in salty climates while the smaller rear pads wear fast. Most of this is maintenance and characteristic; a pedal that sinks while stopped is the exception worth chasing. Brake-test from 30 mph and watch for a pull.

Front-differential needle-bearing groan (4WD trucks)moderate

On four-wheel-drive 4Runners, a cyclical groan or grind from the front differential heard only in two-wheel drive — and gone in four-wheel drive — is a known issue covered by a Toyota service bulletin, caused by a front-differential needle bearing. Mechanics stress it uses an updated part and is not an expensive repair. A separate, benign rear-differential groan (40–60 mph) is one a master tech says to simply live with and keep the fluid fresh. If you hear the front groan when buying, negotiate; don't panic.

Soy-based wiring and rodent damageminor

Rodents chew the soy-based wiring insulation and take out harness sections, with owner repairs commonly declined by warranty as rodent damage. Toyota has a bulletin on whether to repair or replace a chewed harness. It's a parking-and-storage matter rather than a design flaw — relevant if the truck sits outdoors.

Frame and rear-hatch rust — the universal checkmoderate

The generation-wide inspection: salt-belt frames rust, and a rotten frame is a walk-away because replacing it costs more than the truck is worth. The rear hatch rusts under its plastic trim as the trim vibrates through the paint. A southern 2018 avoids the issue; a northern one needs the frame checked from underneath.

Before you buy

Print this
  1. 01Run the VIN and confirm fuel-pump recall 20V-682 shows completed — a stall at speed is the real safety item on a 2018.
  2. 02Verify the 19V-670 steering/suspension-fastener inspection is done if the truck received dealer-installed accessories.
  3. 03On a four-wheel-drive truck, listen for a front-differential groan in two-wheel drive that clears in four-wheel drive — a known, inexpensive needle-bearing fix; a rear groan is benign.
  4. 04Test the brakes: a pedal that sinks while stopped is worth chasing beyond the truck's normal soft feel.
  5. 05Inspect the engine-bay wiring for rodent damage if the truck parks outside.
  6. 06If it lived in a salt-belt state, inspect the frame from underneath and the rear hatch under its plastic trim.
  7. 07Exercise the four-wheel drive through its modes so a seized front differential doesn't surprise you.
