Fuel system, gasoline: deliveryReported January 26, 2011 · 244,779 vehicles affected
What is wrong
Toyota is recalling certain model year 2006-2009 lexus is and model year 2006-2007 lexus gs vehicles. Due to insufficient tightening of the fuel pressure sensor connected to an engine fuel delivery pipe with nickel phosphorus plating, there is a possibility that, over time, the pressure sensor could loosen. If loosening occurs, fuel could leak past a gasket used in the connection between the sensor and the pipe and through the threaded portion of the sensor.
Risk
Fuel leakage, in the presence of an ignition source, could result in a fire.
Remedy
Dealers will inspect for fuel leakage from the threaded portion of the fuel pressure sensor and if a fuel leak is not confirmed, dealers will further tighten the fuel pressure sensor with the proper torque. If a fuel leak is confirmed, the gasket between the sensor and the fuel deliver pipe will be replaced with a new one, and the sensor will be tightened with the proper torque. This service will be performed free of charge. The safety recall began on march 7, 2011. Owners may contact toyota at 1‑800‑331‑4331.

Recall number 11V029000 · Recall details

Service brakes, hydraulic: foundation components: master cylinderReported October 21, 2010 · 728,544 vehicles affected
What is wrong
Toyota is recalling certain model year 2005-2006 avalon, model year 2004-2006 highlander, model year 2004-2006 lexus rx, and model year 2006 lexus gs and is vehicles. Brake fluid containing polymers is used that acts as lubricants for certain brake system components. If replacement brake fluid is used that does not contain such polymers, or that contains only small amounts, a part of the rubber seal located at the rear of the brake master cylinder may become dry, and the seal may curl during movement of the piston. If this occurs, a small amount of brake fluid could slowly leak from the seal into the brake booster.
Risk
A leak of brake fluid could lead to a change in brake pedal feel and overtime a degradation in braking performance increasing the risk of a crash.
Remedy
Dealers will replace the seal with a newly designed one. This service will be performed free of charge. The safety recall began on november 15, 2010. Owners may contact toyota at 1‑800‑331‑4331 and lexus at 1‑800‑255‑3987.

Recall number 10V499000 · Recall details

Vehicle speed control: accelerator pedalReported October 5, 2009 · 4,445,056 vehicles affected
What is wrong
Toyota is recalling certain model year 2004-2010 passenger vehicles. The accelerator pedal can get stuck in the wide open position due to its being trapped by an unsecured or incompatible driver's floor mat.
Risk
A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop the vehicle, which could cause a crash, serious injury or death.
Remedy
Toyota filed an amended defect report on november 25, 2009, stating that dealers will modify the accelerator pedal and, on certain vehicles, alter the shape of the floor surface under the pedal. These changes address the risk of pedal entrapment due to interference with the floor mat. Redesigned accelerator pedals will become available beginning in april 2010 and dealers will replace any modified pedal with the new pedal if desired. Also, dealers will replace any genuine toyota or lexus all-weather floor mats with redesigned all-weather mats, or repurchase the previous mats from owners who do not want the new ones. Additionally, software modifications will be installed on camry, avalon and lexus es 350, is 350 and is 250 models that will ensure that the brake overrides the accelerator in the event both brake and accelerator pedals are applied. Toyota will begin mailing letters to owners on december 31, 2009. Owners may contact toyota at 1‑800‑331‑4331, lexus at 1‑800‑255‑3987.

Risk

Remedy

Risk
Fuel leakage in the presence of an ignition source could result in a fire.
Remedy
Dealers will replace the two involved fuel lines with newly designed lines free of charge. The recall began on december 15, 2007. Owners may contact lexus at 1‑800‑255‑3987.

Risk

Remedy
Dealers will replace the front seat belt assemblies. The recall began on april 21, 2006. Owners may contact lexus at 1‑800‑255‑3987.

Recall number 06V121000 · Recall details

Air bagsReported April 3, 2006 · 133 vehicles affected
What is wrong
On certain vehicles, due to improper assembly of the air bag inflator, which is used in the side air bag, the curtain shield air bag, and the knee air bag assembly, some inflators were produced with an insufficient amount of the heating agents necessary for proper air bag deployment. In this condition, the expansion force of the gas may be insufficient to properly inflate the air bag when the SRS system is activated during a crash.
Risk
This may increase the risk of injury to the occupant in the involved seating position in the event of a crash.
Remedy
Dealers will replace the specific SRS air bag. The recall began on april 6, 2006. Owners may contact toyota at 1‑888‑270‑9371, scion at 1‑866‑548‑1851, or lexus at 1‑800‑255‑3987.

My dashboard is melting and I understand that there was a campaign to resolve this that ended in 2016. I bought the vehicle in 2019 and it has only gotten worse to the point that the dashboard has a sheen to it that causes a glare on the interior of the windshield when the sunlight hits it, making visibility very difficult.

Filed Dec 24, 2024 · Engine · TX

The vehicle is burning engine oil at an increasingly severe rate, with the manual stating that burning 1.1 quarts every 600 miles is normal. This consumption is excessive given the 5.5-quart capacity and the requirement for expensive full synthetic oil, causing frequent and costly top-offs. This poses a safety risk due to the potential for engine damage or failure if oil levels are not closely monitored. Some owners have had the issue inspected, and Lexus has acknowledged the problem. However, they have stated that repairs require replacing components costing multiple thousands of dollars just for parts, leaving many owners without a feasible solution. This problem is widespread, with numerous reports of similar issues in online forums ( [XXX] ]). A thorough investigation and a more customer-friendly resolution are needed to address this design flaw and ensure reliability and safety.

There is a common issue with these makes and models with the drivers side knee air bag having issues with connecting which cause the SRS light go on the dashboard. I called Lexus corporate office and local dealer and they said there was a recall but it expired in 2020. From the research i did, this was a small window and there shouldn’t have been an expiration on the recall for something that is a safety hazard. Because of this, they are charging thousands for this issue that has affected hundreds of thousands of vehicles.

My 2006 Lexus IS350 is subject to the federal safety agency Recall number 16V340, for passenger airbag replacement. According to the diections on the federal safety agency website shown in the following link: [XXX] The dash pad needs to be removed to access the airbag and perform the repair. Ive contacted my 3 local Lexus dealers and was told in various ways that they do not remove the dash to accomplish the repair but instead just remove the glove compartment and associated parts to access the airbag. I wanted the dash replaced (it was cracked) when the old dash was removed to do this recall repair. SInce the dealers do not actually remove the dash, I was told this was not possible. One dealer told me that for an extra $350, the service dept. would do the repair according to the above linked instructions. I have notified Lyndss Tor at [email protected] as well as Toyota Quality Compliance [email protected] and recieved no reply. I hope the federal safety agency can enforce the above linked instructions so that the airbag replacement can be conducted in a proper and safe fasion.
