A durable late-generation 4Runner whose one loud pattern is spontaneous sunroof shatter — inspect the glass, and you've handled its biggest quirk.

The generation's signature shimmy at 50–70 mph persists on 2022 cars, with owners suspecting a front-differential needle bearing and dealers calling it normal. 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. A related front-differential groan (a known, inexpensive needle-bearing fix in 4WD trucks) can drive it. It's a test-drive item, not a safety defect or a drivetrain failure.

The generation's brake story on a 2022: soft, nose-diving pedal feel by design, plus real low-frequency failures — one owner's brake master cylinder was replaced under warranty at 12,600 miles after the pedal sank and the truck wouldn't hold, and another reported an internal brake failure. Caliper and slide-pin seizing with fast rear-pad wear round it out. Most is characteristic and maintenance; a pedal that sinks while stopped is the outlier to chase. Test braking from 30 mph and confirm a firm hold at rest.

Lower-frequency items on the 2022. On Limited trims, the X-REAS hydraulic suspension can fail (one owner at 36k) — expensive if it goes, so drive over rough pavement. A few owners report the plastic oil-filter housing cracking and leaking oil, fixed with an aluminum replacement. And the ADAS — a suite of driver-assist features — draws scattered reports of phantom pre-collision braking and the system disabling itself in rain or snow. None is a deal-breaker, but check each on the test drive.

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 2022 is young, but a northern-climate example still deserves an underside look before you assume it's clean.
