The passenger frontal airbag inflator can rupture when deployed, because the propellant degrades after long-term exposure to high absolute humidity and repeated temperature cycling. A ruptured inflator sends metal fragments into the cabin at the front passenger, and these ruptures have caused serious injuries and deaths across the industry. NHTSA campaign 16V340000 is geographically zoned: 2010-2011 GX460 vehicles are covered where the vehicle was originally sold or has ever been registered in Zone A — Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands. The recall began December 6, 2016. Note that GX460 also appears in the later inflator campaigns 17V006000, 18V024000, 19V005000, and 19V741000.

Common Symptoms

  • No warning symptoms — the defect is latent until deployment
  • Airbag warning light only if an unrelated fault is present

How to Fix

Check the VIN directly against NHTSA rather than reasoning from where the vehicle lives now — eligibility follows where the car was originally sold or has ever been registered, so a truck bought used in a dry state may still be covered by its Florida or Texas history. The dealer replaces the passenger frontal airbag inflator or the complete airbag assembly, free of charge. Because GX460 appears across several sequential inflator campaigns, ask the dealer to run all open airbag recalls on the VIN rather than just the one you called about. Until the repair is done, treat the front passenger seat as the higher-risk position and carry passengers in the rear where practical. Never install a salvage airbag module on this vehicle.

When the 2010 GX 460 is driven through a sharp turn at high speed, the vehicle stability control system intervenes too late and the rear can step out, letting the vehicle skid sideways. On a tall body-on-frame SUV a sideways skid is the precondition for a rollover, particularly if the tires then bite on pavement or a soft shoulder. Consumer Reports issued a rare Don't Buy: Safety Risk rating over this behavior, and Toyota suspended sales before recalling the vehicle. NHTSA campaign 10V159000 covers 2010 GX 460 vehicles manufactured November 16, 2009 through April 8, 2010. The safety recall began May 18, 2010 and the remedy is a reprogramming of the vehicle stability control — no hardware changes.

Common Symptoms

  • Rear of the vehicle slides out during a fast sharp turn
  • Stability control intervening late or abruptly
  • VSC or slip indicator light illuminated
  • Vehicle feels loose or tail-happy in cornering

How to Fix

Confirm by VIN that the VSC reprogramming under recall 10V159000 was performed — this is a fifteen-year-old software campaign on a vehicle that has changed hands many times, and there is no way to tell by driving it normally whether the update is present. The dealer performs it free of charge. Independent of the recall, be aware that the GX 460's high center of gravity rewards conservative cornering speeds regardless of software, and that worn or mismatched tires and a failed rear height control sensor both degrade stability control's ability to intervene. If the VSC or slip indicator lights are on, the system is at least partly disabled and the vehicle should be diagnosed before being driven hard.

NHTSA recall 25V744000 includes 2024-2025 Lexus GX models fitted with the Panoramic View Monitor. A software fault in the parking assist system can leave the GX's reverse image frozen or the screen entirely blank at the moment the driver selects reverse. On a tall, boxy SUV with a full-size rear door and spare-tire carrier, the camera is a primary rearward view, and Toyota states the failure puts the vehicle out of compliance with FMVSS 111, "Rear Visibility." Toyota reports the consequence as a reduced view behind the vehicle and an increased risk of a crash. The campaign covers about 1,024,407 vehicles across all Toyota, Lexus, and Subaru Solterra models involved - that is the total for the whole campaign, not for the GX.

Common Symptoms

  • Reverse camera view sticks on a frozen frame
  • Screen goes blank when shifting into reverse
  • No rear image from the Panoramic View Monitor

How to Fix

Lexus dealers will update the parking assist software free of charge; no parts are replaced. Owner letters went out January 2, 2026 under Toyota recall numbers 25TB13 and 25LB06. Check your GX by VIN at nhtsa.gov/recalls, or contact Toyota customer service at 1-800-331-4331 to schedule the software update.

The secondary air injection (SAI) system pump and switching valves fail due to moisture intrusion and corrosion. The SAI pump introduces fresh air into the exhaust during cold starts to reduce emissions, but the pump motor corrodes internally and the switching valves stick. This triggers a check engine light with SAI-related codes.

This issue also affects: Toyota 4Runner, Toyota Tacoma, Toyota FJ Cruiser

Common Symptoms

  • Check engine light with P2440/P2441/P2442 codes
  • Rough idle on cold start
  • Failed emissions inspection
  • Whirring noise from passenger side of engine on cold start

How to Fix

Replace the secondary air injection pump and switching valves. Clean or replace the air injection check valves. Clear codes and verify operation. Some owners in non-emissions-testing states choose to bypass the system entirely with a tune.

The secondary air injection system pumps air into the exhaust on cold start to light the catalysts faster. On the GX 460 it fails in two related ways. The foam filter inside the air injection pump disintegrates with age and the debris is drawn into the system, blocking the air switching valves and lines downstream. Separately, and in the large majority of failures, the diverter or air switching valve corrodes from moisture contamination. Either failure sets emissions codes and drops the vehicle into limp mode, which owners experience as a sudden dramatic loss of power on a cold morning, usually on the first drive of the day. Lexus acknowledged the defect for 2010-2013 GX 460 vehicles with the 1UR-FE engine in a Special Service Campaign (bulletin L-SB-0028-14) covering MIL-on conditions with DTC P0418, P2440, P2442 and/or P2445, under which the pump filter and air switching valves are replaced at no charge. This is the same architecture that troubles the 2010-2013 Tundra, Sequoia, and LX 570.

This issue also affects: Toyota 4Runner, Toyota Tacoma, Toyota FJ Cruiser

Common Symptoms

  • Sudden loss of power and limp mode on cold start
  • Check engine light with secondary air injection codes
  • Loud whirring or buzzing from the engine bay on cold start
  • Rough running for the first minute after a cold start
  • Failed emissions test

How to Fix

Before paying for anything, check the VIN against the Lexus Special Service Campaign (bulletin L-SB-0028-14): for affected 2010-2013 GX 460 vehicles the dealer replaces the air injection pump filter with an improved-design part and replaces the air switching valves free of charge, and will replace the air injection pump itself as needed at no cost. Many owners pay several thousand dollars for this repair without ever learning the campaign exists, so make this call first. If the vehicle is outside the campaign, diagnose which half has failed before buying parts, because the pump and the valves are priced very differently. Pull the codes and inspect the pump's foam filter — if it has disintegrated, replacing valves alone guarantees a repeat failure because the debris is still in the system, so the lines must be cleared too. If the pump filter is intact, the odds strongly favor a corroded diverter or air switching valve. Fit the improved-design filter so the failure does not recur. Some owners fit an aftermarket bypass or delete to escape the failure loop, but understand that this defeats an emissions control device, will fail inspection in most states, and is illegal to perform on a road vehicle.

The Kinetic Dynamic Suspension System (KDSS) on the GX460 develops hydraulic fluid leaks from the stabilizer bar actuators and hydraulic lines. Leaks cause the KDSS warning light to illuminate and the system to become inoperative, resulting in increased body roll and a less controlled ride. The front actuators are the most common failure point.

This issue also affects: Lexus LX, Toyota 4Runner, Toyota Land Cruiser

Common Symptoms

  • KDSS warning light on dashboard
  • Hydraulic fluid leak under vehicle
  • Increased body roll in corners
  • Clunking noise from suspension over bumps
  • Visible fluid on stabilizer bar actuators

How to Fix

Replace the leaking KDSS actuator(s) and hydraulic lines. Refill and bleed the system with the correct Toyota KDSS fluid. Both front and rear actuators should be inspected even if only one is leaking. Some owners disconnect the KDSS system and install conventional sway bars.

A persistent complaint across the entire GX 460 production run is that the truck sits noticeably lower on the right side, commonly around an inch. It affects many but not all examples and shows up on vehicles with and without the AHC hydraulic system. On AHC-equipped trucks the cause is usually within the height control system — a failing height control sensor or accumulator pressure loss — and is correctable. On non-AHC trucks the lean is generally a combination of spring rate tolerance, the asymmetric weight of the fuel tank and driveline, and settled springs on an older vehicle, and it is not a fault so much as an accumulation of tolerances. The distinction matters because the two situations call for completely different responses.

Common Symptoms

  • Vehicle sits roughly an inch lower on the right side
  • Uneven fender-to-ground measurements when unloaded
  • Uneven tire wear across the vehicle
  • AHC system slow to level or unable to hold height
  • Lean more pronounced after the vehicle has been parked

How to Fix

Measure before diagnosing: park on genuinely level ground, ensure the tires are at equal pressure, and measure from the ground to the same point on each fender at all four corners with the vehicle unloaded. Note that a half-tank of fuel and a heavy set of tools in one side of the cargo area account for more lean than owners expect. On AHC-equipped trucks, have the height control sensors read on a scan tool and the accumulator pressure checked before replacing anything — a failing sensor is a far more common and cheaper cause than a failed sphere. On non-AHC trucks, if the lean is genuinely a settled spring, replacing the springs in axle pairs restores it; never shim or spacer only one side to mask a lean without first confirming the springs and the frame are sound. If the lean appeared suddenly rather than gradually, stop treating it as a tolerance issue and inspect for a broken spring, a failed shock, or accident damage.

The center differential lock actuator on the GX470 fails due to internal motor wear and electrical contact corrosion. When the actuator fails, the center diff lock cannot be engaged for low-range off-road use. The actuator is mounted on the transfer case and is exposed to road debris and moisture.

This issue also affects: Lexus LX, Toyota Land Cruiser, Toyota Sequoia

Common Symptoms

  • Center diff lock indicator flashes but does not engage
  • Center diff lock switch has no effect
  • Clicking sound from transfer case when trying to engage
  • AWD warning light on dashboard

How to Fix

Replace the center differential lock actuator motor. The actuator is accessible from under the vehicle on the transfer case. Use the OEM Toyota actuator for reliability. After replacement, verify engagement by testing in a straight line at low speed on a loose surface.
