1997-2025 Lexus ES Problems: 16 Known Issues

On 2007-2008 ES 350 models built with the 3.5L 2GR-FE V6 (engines produced before April 2008), the variable valve timing (VVT-i) oil supply line uses a short rubber hose section joining two metal pipes outside the block. It carries hot, high-pressure oil, and the rubber degrades with heat and age until it splits or blows off, dumping the engine's entire oil charge in seconds. Owners report a sudden oil-pressure light and a cloud of smoke, and engines that are driven even a short distance after the rupture are frequently destroyed. Toyota/Lexus addressed it with Limited Service Campaign 9LH (a special service campaign, not an NHTSA safety recall), replacing the hose with a revised part; engines built from April 2008 onward received an all-metal line from the factory.

The 3.0L 1MZ-FE V6 in the 1997-2002 ES 300 is one of the core engines in Toyota's oil-gelation controversy. A combination of crankcase ventilation design and a 7,500-mile service interval let oil oxidize into a thick sludge that coats the valve covers and plugs the oil pickup screen and small oil passages, starving bearings and rings. Symptoms progress from a persistent low-oil-level and blue smoke to a knocking bottom end. Toyota settled a class action covering roughly 3.5 million 1997-2002 Toyota and Lexus vehicles with the affected engines, agreeing to repair sludge-damaged engines for up to 8 years from purchase with third-party mediation for denied claims. That settlement window has long closed, so today this is a buyer-beware inspection item rather than a covered repair.

The 3.5L 2GR-FE V6 in the ES350 consumes excessive oil between changes, often burning 1 quart every 1,500-2,500 miles. The root cause is typically worn piston rings that allow oil past the ring lands into the combustion chamber. Unlike Toyota's 2AZ-FE four-cylinder, there is no Toyota/Lexus bulletin or piston revision for the 2GR-FE; this is an owner-reported pattern, not a factory-acknowledged defect.

The 2GR-FE V6 seals its front timing chain cover to the block and heads with a formed-in-place sealant (FIPG) rather than a conventional gasket. On early 2007-2009 engines the seal breaks down and weeps oil from the front of the engine, dripping onto the subframe, front control arm bushings, and steering rack, and occasionally onto the exhaust. Toyota largely resolved the problem in production by about the 2010 model year. The repair is notorious because reaching the cover requires dropping the engine, transmission, steering rack, and front subframe - Toyota's own labor estimate runs around 20+ hours for a roughly $20 gasket and sealant, so dealer quotes commonly land between $2,400 and $4,000.

On the 1MZ-FE V6 the two knock sensors sit in the valley between the cylinder heads, and their sub-harness bakes there under the intake manifold. The wire insulation hardens and chafes, shorting the signal wire to ground and setting P0325 (knock sensor 1 circuit) and/or P0330 (knock sensor 2 circuit). The ECU responds by pulling timing, so the car runs down on power and mileage with a permanent check engine light. The recurring forum lesson is that the harness - not the sensors - is usually the failed part: owners who replace only the sensors see the code return within days.

The 2007-2012 ES 350 carries a Takata front passenger airbag inflator whose ammonium-nitrate propellant degrades after long exposure to high humidity and temperature cycling. A degraded inflator can over-pressurize and burst its metal housing during a crash, spraying fragments into the cabin. The ES 350 was pulled in over several NHTSA campaigns as the Takata recall expanded by humidity zone: 16V340 (Zone A - Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas and U.S. territories), 17V006 (further regional expansion), and 19V741 (re-replacement of inflators that had been installed under an earlier recall with a part of the same design). This is one of the most serious open recalls on used ES 350s, and unremedied cars are still on the road.

The XV40 ES 350 was the vehicle that opened NHTSA's pedal-entrapment investigation: in March 2007 the agency began a preliminary investigation into the 2007 ES 350 after consumer complaints alleging crashes and injuries, with the accessory all-weather floor mat identified as the likely cause. Toyota first recalled about 55,000 floor mats for 2007-2008 Camry and ES 350 (NHTSA campaign 07E082), then in 2009 issued the far broader floor-mat/pedal-entrapment recall 09V388 covering 2007-2010 ES 350 among other models. The accelerator pedal can be held wide open by an unsecured, stacked, or incompatible driver's floor mat, and the driver cannot free it while the car accelerates.

Lexus ES sedans built for the 2023-2025 model years and equipped with the Panoramic View Monitor (PVM) system are covered by NHTSA recall 25V744000. Toyota reports a software error that can cause the ES rearview camera to freeze on a stale image or show a blank screen when the car is shifted into reverse. Because the required rear image is not displayed, the affected vehicles do not comply with Federal Motor Vehicle Safety Standard 111, "Rear Visibility." The campaign as a whole covers roughly 1,024,407 Toyota, Lexus, and Subaru Solterra vehicles; that figure is campaign-wide and not specific to the ES.

The U140E four-speed (1999-2001 ES 300) and U151E five-speed (2002-2003 ES 300 and 2004-2006 ES 330) automatics used behind the 1MZ-FE and 3MZ-FE have two distinct documented failure patterns. Higher-mileage 1999-2003 ES 300 units slip - typically after the fluid warms up a couple of minutes - as the clutch packs and valve body wear, ending in a burnt pack and no drive. Separately, the 2002-2006 cars are known for a shift-logic hesitation and momentary surge from a rolling start that Toyota treated as a drivability/customer-satisfaction issue and addressed with control software revisions; the 2004-2006 ES 330 in particular drew heavy complaint volume for slow, inconsistent shifting.

The U660E six-speed automatic introduced on the 2007 ES 350 has a well-documented shift flare: on the first upshifts after a cold soak the engine speed rises 300-700 rpm before the gear engages, most commonly on the 3-4 upshift but also reported on 2-3, 4-5, and the 5-4 downshift when transitioning between coast and light throttle. Toyota issued transmission TSBs (including TC007-07) with revised ECM/TCM calibrations. Forum consensus splits the units by build date: earlier units (through roughly 06/2006 production) were generally cured with a valve body and solenoid replacement plus a reflash, while later units often needed more, up to transmission replacement. Left unaddressed, repeated flaring glazes the clutch packs.

The ES300h hybrid battery pack experiences capacity degradation over time, particularly in hot climates where thermal cycling accelerates cell deterioration. Owners report reduced fuel economy, inability to maintain EV mode, and eventually a hybrid system warning light. The NiMH battery pack typically begins showing degradation between 8-12 years of age.

The 2019 ES 350 (and other 2019 Lexus models) were recalled under NHTSA campaign 20V012 for a Denso-supplied low-pressure in-tank fuel pump. The impeller was molded from a lower-density resin that absorbs fuel, swells, deforms, and binds against the pump housing. The result is a rough-running engine, a no-start, or - the safety issue - a stall at speed with no warning. Toyota's January 2020 recall covered roughly 131,000 vehicles initially and has been amended and expanded repeatedly since, with the most recent amendment in January 2025. Related class-action filings alleged that some 2018-2019 vehicles with the same pump were left out of the original scope.

Lexus technicians and owners report that high-mileage 2007-2012 ES 350s commonly lose refrigerant through a leaking evaporator core buried in the HVAC case behind the dash. The symptom is gradual: air that is cool but not cold, worse in traffic, and a system that cools again briefly after a recharge before fading over weeks or months. Because the evaporator is inside the dash, replacement is a labor-heavy job - a ClubLexus master technician put the repair comfortably over $1,500. The A/C condenser at the front of the car is a separate, cheaper failure point on the same generation, usually punctured by road debris.

Lexus programs ZLD and ZLZ document cracked and/or sticky dashboard surfaces caused over time by heat, humidity and, in ZLZ, light intensity on covered ES 350 vehicles. ZLD covers certain 2007-2008 vehicles and ZLZ covers certain 2008-2012 vehicles. The condition is cosmetic.

On the otherwise very reliable 2013-2018 ES 350 (2GR-FE), the engine-driven water pump is the standout mechanical failure. The bearing and seal wear, producing a squeal or chirp that is loudest on a cold start and a slow coolant weep from the pump's telltale hole. Owners on ClubLexus and the Lexus Owners Club repeatedly report the noise being diagnosed first as a serpentine belt or idler pulley, with the belt replaced before the pump is found to be the real source. Failures cluster between roughly 60,000 and 120,000 miles, and replacement typically runs several hundred to well over a thousand dollars depending on shop.

The electronic brake actuator on the 2019+ ES produces a noticeable buzzing or grinding noise during low-speed braking and when the brake hold function is engaged. The noise comes from the ABS actuator cycling at low speeds and is a design characteristic of the brake-by-wire system. While not a safety concern, the noise is prominent enough to be heard in the cabin.
