On the 2006 Lexus GS, the 2006 Lexus GS is included in NHTSA recall campaign 06V096000, which covers an improperly assembled air bag inflator used in the side air bag, the curtain shield air bag and the knee air bag assembly. Affected inflators were built with an insufficient amount of the heating agents necessary for proper air bag deployment. Should the SRS system activate during a crash, the expansion force of the gas may be insufficient to properly inflate that air bag, which increases the risk of injury to the occupant in the involved seating position. On a car with as many air bags as the GS, this affects only the specific assembly that received a suspect inflator — the remaining restraints are unaffected. There is no owner-detectable sign of the condition. NHTSA's 133-unit count is the campaign total across all Toyota, Scion and Lexus vehicles covered, not a GS figure.

How to Fix

Lexus dealers will replace the specific SRS air bag involved at no cost to you. Provide the VIN and the dealer will determine which air bag assembly on your GS is subject to the campaign. The recall began April 6, 2006 and there is no expiration on the free repair. Check whether 06V096000 is still open against your VIN at nhtsa.gov/recalls, and contact Lexus customer assistance at 1-800-255-3987 for help arranging the work.

On the 2006-2011 Lexus GS, s190 GS models fitted with the electronically controlled brake (ECB) system - the GS 430, GS 450h and GS 460 - use a brake actuator assembly containing an electric pump motor that maintains accumulator pressure. The pump motor's commutator wears, and once worn the motor can stop in a position from which it will not restart, which is why the failure presents as sudden and total rather than gradual. Owners report a clunking or clicking through the pedal, a buzzing/whining/groaning from the engine bay that continues even after the car is shut off (the pump cycling repeatedly), and a full cluster of ABS, BRAKE, VSC and traction control lights. Note the generation and drivetrain discipline here: the GS 350 uses a conventional vacuum-boosted system and is not affected - this is specific to the ECB-equipped V8 and hybrid cars. Lexus ran a goodwill campaign covering the actuator but the coverage cutoff has passed, so out-of-warranty owners pay.

Common Symptoms

  • ABS, BRAKE, VSC and traction control warning lights all illuminated
  • Buzzing, whining or groaning from the engine bay, including with the car off
  • Clunking or clicking felt through the brake pedal
  • Hard brake pedal and reduced braking assist
  • Brake warning buzzer

How to Fix

Replacement of the brake actuator assembly is the factory fix; dealer quotes commonly exceed $4,000, independent shops around $2,300 with a new unit. Used units carry the same wearing pump motor and are a gamble. A growing cottage industry rebuilds the pump motor/commutator for far less, which ClubLexus owners have documented as a viable route. Do not ignore the buzzing-after-shutdown symptom - it means the accumulator is not holding pressure and braking assist can be lost.

Typical repair cost:$900 - $4,500

On the 2006-2007 Lexus GS, early S190 cars (2006-2007 GS) were built with aluminum fuel delivery pipes. Ethanol-blended gasoline with low moisture content attacks the internal surface of the aluminum rail. The corrosion progresses until it eats a pinhole through the pipe wall, at which point gasoline leaks under pressure - a fire risk. Before the pinhole forms, the malfunction indicator lamp typically illuminates as the corrosion products and pressure irregularities upset fuel trims. Toyota recalled roughly 214,570 vehicles across 2006-2008 Lexus IS, 2006-2007 GS and 2007-2008 LS. This is a generation-specific hardware issue on the first two model years of the S190 body only; later S190 cars got revised rails, and the separate 18V432 pulsation-damper campaign is a different defect on the same family of parts.

Common Symptoms

  • Check engine light
  • Fuel odor
  • Visible fuel seepage at the fuel rail
  • Rough running or hard start

How to Fix

NHTSA recall 09V020000 (Lexus code 9LA), remedy began February 2009. Dealers inspect and replace the aluminum fuel delivery pipes free of charge. Verify by VIN at nhtsa.gov/recalls. A 2006-2007 GS with an unexplained check engine light and a fuel odor should be checked for this before chasing sensors.

Typical repair cost:$0 - $0

On the 2006-2012 Lexus GS, the GS dashboard suffers from the same melting and sticky surface defect as other Lexus models of this era. Heat exposure causes the dashboard material to chemically degrade, resulting in a shiny, tacky surface that creates dangerous glare on the windshield. This was a widespread issue across the Lexus lineup.

This issue also affects: Lexus LS, Lexus SC, Lexus ES

Common Symptoms

  • Dashboard surface becomes sticky to touch
  • Reflective glare on windshield from melted dashboard
  • Material cracking and peeling
  • Chemical smell from dashboard in warm weather

How to Fix

Lexus Customer Support Program ZE7 covers dashboard replacement. Contact your dealer or Lexus customer support at 1-800-255-3987. The entire dashboard assembly and associated trim panels are replaced with redesigned materials.

Owner tips & cautions

  • TipUse a windshield sun shade religiously to slow the dashboard deterioration. Document the condition with photos as evidence for your warranty claim.

On the 2006-2015 Lexus GS, the power steering rack develops internal seal leaks that cause power steering fluid loss. The leak typically appears at the inner tie rod boots where fluid seeps past the rack seals. Low fluid levels lead to increased steering effort and pump whining noise, and eventually the rack must be replaced.

This issue also affects: Lexus LS, Lexus SC, Lexus IS

Common Symptoms

  • Power steering fluid leaking from rack area
  • Whining noise when turning steering wheel
  • Increased steering effort especially at low speed
  • Power steering fluid level drops
  • Fluid-soaked inner tie rod boots

How to Fix

Replace the power steering rack assembly. Remanufactured racks are available from Maval and Cardone at significant savings over new OEM. Perform a complete power steering fluid flush after installation. Inspect tie rods and replace if worn.

Owner tips & cautions

  • TipCheck the inner tie rod boots regularly for fluid wetness — this is the earliest sign of a leaking rack. Catching it early prevents pump damage from running low on fluid.

On the 2006-2020 Lexus GS 2GR-FSE, the 2GR family V6 - including the 2GR-FSE fitted to the S190 GS 350 / GS 450h and the L10 GS 350 - seals its front timing chain cover and cam housings with FIPG (formed-in-place gasket) sealant rather than a solid gasket. Over years of heat cycling the sealant hardens, shrinks and loses adhesion, and engine oil weeps from the timing cover seam and the cam housing joints. ClubLexus describes this as the one major problem of the 2GR V6 and calls it a question of when, not if. The cruel part is the repair geometry: on the longitudinal rear-drive GS there is not enough clearance to pull the timing cover with the engine in the car, so the front subframe with engine and transmission has to come down - a 20+ hour job. Many owners live with a slow weep for years and top off oil instead. This is distinct from the simple valve-cover gasket weep on the older S160 cars.

Common Symptoms

  • Oil drips on the driveway under the front of the engine
  • Burning oil smell after driving
  • Oil residue down the front of the block and on the subframe
  • Gradually dropping oil level between changes

How to Fix

The correct repair is to drop the subframe/engine, strip the front of the engine, clean every mating surface back to bare metal and re-seal the timing cover and cam housings with fresh Toyota FIPG. Dealer quotes commonly run $2,400-$4,000 and independent Lexus specialists somewhat less. Because it is a slow seep and not a safety item, the accepted practical approach is to monitor oil level, keep the seep off the exhaust and accessory belt, and only commit to the teardown when the loss becomes significant or when the engine is already out for other work. Stop-leak additives do not fix a failed FIPG joint.

Typical repair cost:$2,400 - $4,000
