The A/C compressor can fail prematurely, often sending metal debris throughout the system. When the compressor fails, the entire A/C system typically needs to be flushed and the condenser, drier, and expansion valve replaced along with the compressor to prevent repeat failure. Repairs typically run $1,200-$2,500. Severity: medium.
The starter on 2010-2022 4Runners is prone to corrosion, and if corrosion migrates into the starter relay/solenoid contacts it can cause intermittent no-crank (a single click or nothing on key turn) and, in some cases, additional driveability gremlins. Because the starter sits lo… Repairs typically run $150-$500. Severity: medium.
On 5th-gen 4Runners the door lock actuator is built into the door latch assembly and fails frequently, often just outside the factory warranty. Owners find one or more doors that no longer lock or unlock with the key fob or interior switch, sometimes with a rapid clicking from in… Repairs typically run $90-$350. Severity: medium.
The signature rear tailgate power glass on the 4Runner is a high-failure, high-search item. The window stops rolling up or down, rolls part way and falls back, moves slowly/unevenly, or makes grinding noises. Root causes are a worn rear window regulator/motor sub-assembly, a fail… Repairs typically run $120-$500. Severity: medium.
The accessory-drive belt tensioner and idler pulley bearings (a 6203-size sealed bearing) wear out and get noisy on the 1GR-FE, producing a persistent squeal/squeak/grinding from the front of the engine that is often mistaken for the water pump or a glazed belt. A weak tensioner… Repairs typically run $40-$350. Severity: medium.
On higher-mileage 4Runner automatics owners report harsh/abrupt shifts, jerky 3-2 downshifts, unstable RPM blips while coasting near 40 mph, and delayed engagement. The most common mechanical cause is valve-body pressure control wear - a sticking pressure-regulator or throttle va… Repairs typically run $150-$1,500. Severity: medium.
A clunk or pop may be heard from the steering column area when turning the wheel, especially at low speeds or when going from left to right. The issue is typically the intermediate steering shaft or worn rack bushings. Common on vehicles driven off-road. Repairs typically run $50-$1,500. Severity: low.
Some 5th gen 4Runners develop a whining noise from the rear differential, especially noticeable at highway speeds (40-60 mph). The noise is often related to differential gear setup from factory or premature bearing wear. Repairs typically run $100-$3,000. Severity: low.
The HVAC air-mix (blend) door servo actuators use plastic internal gears that strip over time. When a gear tooth breaks the servo loses calibration and produces a repetitive clicking/ticking sound behind the glove box or center dash, and the climate system can no longer regulate… Repairs typically run $60-$350. Severity: low.
The sunroof tray has plastic drain tubes at each corner that route water down the A-pillars (front) and into the rear pillars, exiting near the rockers.
