Reliability report · 2023 Toyota 4Runner · Updated July 2026 · ~$3,650/yr fuel · what it costs to keep →

The final V6 4Runner before the redesign — a bulletproof truck whose new gripes are a distracting LED-headlight shadow and a pricey brake-accumulator failure.

The 2023 is the last of the fifth-generation, V6-powered 4Runners before the 2025 redesign — the same bulletproof 4.0-liter 1GR-FE V6 and A750 five-speed automatic, and the smallest complaint file of the 2016–2023 range at just 30 entries. Its only recall is a regional-distributor load-capacity label.

Two newer complaints shape this year. The LED low beams cast a distracting shadow or dark blotch that owners call a design flaw and dealers call 'a characteristic' — test the headlights at night. And a handful of owners hit expensive brake master-cylinder or accumulator failures ($3,200 quoted out of pocket in one case) — rare, but worth a careful brake test. Add the generation's shimmy, sunroof-shatter, and salt-belt frame checks and you've covered a 2023.

Canary status

Chirping

What that means: 30 federal complaints — the smallest file of the range — and a single accessory load-label recall, with no national safety recall touching this year. The 4.0-liter V6 and five-speed automatic are unchanged and bulletproof. Two newer gripes stand out: a distracting LED low-beam shadow that owners call a design flaw, and a small number of expensive brake master-cylinder/accumulator failures.

LED low-beam shadow / dark blotch

moderate

A newer, distinctly 2023 complaint: the LED low beams throw a shadow or dark blotch on the driver's side, roughly at the 10–11 o'clock position, that owners find distracting at night — 'my eyes are drawn to it,' 'looks like an animal running across the road.' It disappears on high beam. Dealers and Toyota call it 'a characteristic of the vehicle' and decline to fix it, and multiple owners report the same. It's an annoyance-and-visibility gripe, not a mechanical failure, but drive the truck at night before buying if you commute in the dark.

Brake master-cylinder / accumulator failuresmoderate

The 4Runner's brakes feel soft by design, but the 2023 file carries a few genuinely expensive failures: one owner faced a failed brake accumulator — part of the master-cylinder assembly — at 41k quoted at $3,200 out of pocket, and another reported a stiff-pedal crash at 9k. These are low-frequency, but pricier than the caliper-and-pad wear that's more common on the generation. Test the brakes thoroughly — firm hold at a stop, no sinking pedal, no warning lights — and factor a master-cylinder assembly into your risk math on a higher-mileage example.

Highway steering shimmy and differential groanmoderate

The generation's signature shimmy at 55–70 mph continues on 2023 cars, with owners citing forum consensus about a needle bearing and one finding a service bulletin that matched their VIN — the dealer replaced the front differential and the shake persisted. Toyota's tech tips tie much of it to the factory tires; mechanics say a body-on-frame truck on aggressive tires is inherently prone to it, best improved with better tires and a road-force balance. It's a test-drive item, not a safety defect or a drivetrain failure.

Sunroof shatter, windshield, and camera quirksminor

Generation-wide items in the 2023 file. The sunroof can shatter spontaneously with no recall (insurance is the backstop). Several owners report the windshield cracking easily or making a cold-weather snapping noise, and the backup camera drawing grainy or dark images. One quirk unique to the newer software: changing the lock-sound-volume setting bricked a key fob. None is a deal-breaker; inspect the glass and test the camera and fob on the drive.

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. The rear hatch rusts under its plastic trim. A 2023 is nearly new, but a northern-climate truck still deserves an underside look before you assume it's clean.

Before you buy

Print this
  1. 01Drive the truck at night and judge the LED low beams for the driver's-side shadow/blotch — Toyota won't fix it, so decide if it bothers you.
  2. 02Test the brakes thoroughly: firm hold at a stop, no sinking pedal, no warning lights; a master-cylinder/accumulator failure is rare but expensive.
  3. 03Drive at 55–70 mph and feel for steering-wheel shimmy; plan on a road-force balance or better tires rather than assuming a broken part.
  4. 04Inspect the sunroof and windshield glass and ask about prior claims; test the backup camera and the key fob.
  5. 05If it lived in a salt-belt state, inspect the frame from underneath and the rear hatch under its plastic trim for rust.
  6. 06The one recall (23V-680) is a free load-label replacement — verify it by VIN.
  7. 07Exercise the four-wheel drive through its modes so a seized front differential doesn't surprise you.
