The 2006 IS 250 with the 2.5L V6 (4GR-FSE) is a well-built sport sedan undermined by a catastrophic design flaw: carbon buildup on intake valves causes complete engine failure requiring rebuild or replacement, typically between 80,000-150,000 miles.
Carbon Buildup Leading to Engine Failure (4GR-FSE Direct Injection)
Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: rough idle and misfires starting around 60k-80k miles, progressive loss of power, eventually valves stick open causing piston/cylinder wall contact, catastrophic bearing failure, scored cylinders, bent valves
Fix: Direct injection means no fuel washing intake valves. Carbon accumulates until valves can't close properly. Early stages require walnut blasting (~4-6 hrs labor). Once engine damage occurs, you're looking at full rebuild with new pistons, rings, bearings, head work, or short block replacement (40-60 hrs labor). Many shops recommend replacing rather than rebuilding due to extent of damage.
Estimated cost: $8,000-15,000
Transmission Oil Cooler Failure
Occasional · high severity
Typical onset: 100,000-140,000 mi
Symptoms: transmission fluid mixing with coolant (strawberry milkshake in reservoir), transmission slipping or harsh shifts, overheating
Fix: Internal cooler in radiator fails, cross-contaminating fluids. Requires radiator replacement, complete transmission fluid flush (multiple cycles), often transmission filter and pan service. If contamination went unnoticed, transmission rebuild needed (20-25 hrs). Catch it early and you're looking at 4-5 hrs labor.
Symptoms: dashboard becomes sticky/tacky to touch, reflective glare on windshield, bubbling or delaminating surface
Fix: Defective dashboard material breaks down, especially in hot climates. Lexus extended warranty covered this through 2017 but most are now out of coverage. Requires complete dashboard replacement (8-10 hrs labor, must remove windshield, entire instrument cluster, steering column components). Many owners live with it or use dash covers.
Estimated cost: $2,000-3,500
Transmission Mount Failure
Common · medium severity
Typical onset: 90,000-130,000 mi
Symptoms: clunking when shifting from park to drive/reverse, excessive vibration at idle, rough engagement into gear
Fix: Rear transmission mount deteriorates. Relatively simple fix at 2-3 hrs labor, but often discovered during diagnosis of other drivetrain issues.
Estimated cost: $350-600
Water Pump Failure
Occasional · medium severity
Typical onset: 90,000-120,000 mi
Symptoms: coolant leak from front of engine, whining or grinding noise, overheating
Fix: Not a timing belt engine (chain-driven), but water pump still fails. Access is tight on this V6. 4-5 hrs labor. Always replace thermostat at same time.
Estimated cost: $700-1,100
VVT-i Actuator Rattle
Occasional · low severity
Typical onset: 70,000-110,000 mi
Symptoms: loud rattle on cold start for 2-3 seconds, sounds like marbles in a can, goes away once oil pressure builds
Fix: Variable valve timing actuators (cam gears) develop internal wear. Mostly a noise issue, rarely causes failure. Each bank has one actuator. 3-4 hrs per side if you're just doing actuators. Many owners live with it.
Estimated cost: $800-1,400 (both banks)
Owner tips
Walnut blast intake valves every 60,000-70,000 miles religiously ($400-600) — this is THE preventive measure that determines if you keep this car or throw it away
Use Top Tier gasoline and occasional Italian tune-up (high-RPM runs) to minimize carbon, though direct injection makes buildup inevitable
Check coolant reservoir for milky appearance every oil change to catch transmission cooler failure early
Change transmission fluid every 30,000 miles even though Lexus calls it lifetime — this transmission doesn't tolerate neglect
Only buy if you can verify religious valve cleaning history or plan to budget $10k for engine replacement — the 4GR-FSE carbon issue is not 'if' but 'when,' making these a gamble despite Toyota/Lexus build quality elsewhere.

2019-10-17 · EA15001
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2016 4Runner, 2003-2006 Tundra, 2003-2013 Corolla, 2009-2010 Corolla Matrix, 2004-2005 RAV4, 2002-2007 Sequoia, 2011-2013 Sienna, 2008-2012 Scion xB, 2008-2009 Lexus IS-F, 2007-2012 Yaris and Lexus ES350, 2010-2017 Lexus GX460, 2002-2010 Lexus SC430, 2006-2012 Lexus IS250 and IS350 and 2010-2015 Lexus IS250C and IS350C vehicles.
These vehicles had their driver or passenger frontal air bag inflators previously replaced under a prior recall using inflators of the same design. The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling.
Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Toyota will notify owners. Depending on the vehicle model, dealers will replace the front driver inflator, front passenger airbag inflator, the airbag assembly, or the front passenger airbag sub-assembly and inflator. The recall began November 20, 2019. Owners may contact Toyota customer service at 1-888-270-9371 or Lexus customer service at 1-800-255-3987. Toyota's numbers for this recall are J0A, J0B, and J0C. Lexus' numbers for this recall are JLI, JLJ, and JLK.

These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
Consequence: An inflator rupture may result in metal fragments striking the vehicle occupants resulting in serious injury or death.
Remedy: Toyota will notify the Toyota, Scion and Lexus owners. General Motors will contact the Pontiac owners. Depending on the model, dealers will replace the passenger frontal air bag inflator or the air bag assembly, free of charge. The recall began on February 1, 2017.

Due to anti-corrosion plating remnants, fuel may leak from where the fuel pressure sensor is attached to the fuel delivery pipe.
Consequence: A fuel leak in the presence of an ignition source increases the risk of a fire.
Remedy: Toyota will notify owners, and dealers will clean and reseal the fuel pressure sensor mounting area, free of charge. The recall began March 3, 2015. Owners may contact Toyota customer service at 1-800-331-4331.

Toyota is recalling certain model year 2006-2012 Lexus IS250 and IS350 vehicles manufactured August 23, 2005, through October 5, 2011; 2010-2012 Lexus IS250C and IS350C vehicles manufactured April 10, 2009, through October 6, 2011; and 2008-2011 Lexus IS-F vehicles manufactured December 14, 2007, through July 10, 2011. The nuts that fasten the wiper arms may be insufficiently torqued such that if the wiper arms are restricted by an external load, such as a buildup of heavy snow, one or both of the wipers may become inoperative.
Consequence: Inoperative wipers could reduce driver visibility and increase the risk of a vehicle crash.
Remedy: Toyota will notify owners, and Lexus dealers will install new wiper arm nuts, free of charge. An interim letter was mailed to owners on April 4, 2013. Owners may contact Toyota at 1-800-331-4331.
ON CERTAIN PASSENGER VEHICLES, THERE IS A POSSIBILITY THAT THE ACCELERATOR PEDAL MAY TEMPORARILY BECOME STUCK IN THE PARTIALLY DEPRESSED POSITION DUE TO INADEQUATE CLEARANCE BETWEEN THE ACCELERATOR PEDAL LINKAGE AND A PLASTIC PAD EMBEDDED INTO THE VEHICLE'S CARPET.
Consequence: THIS CONDITION MAY INTERFERE WITH THE ACCELERATOR PEDAL RETURNING TO THE IDLE POSITION, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT THE CLEARANCE OF THE ACCELERATION PEDAL AND CARPET, REPLACE THE PEDAL ASSEMBLY WITH A REVISED ASSEMBLY, AND MODIFY THE CARPET FREE OF CHARGE. THE RECALL BEGAN ON DECEMBER 27, 2005. OWNERS MAY CONTACT LEXUS AT 1-800-255-3987.
