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.

My vehicle's dashboard was melting. I thought it was some kind of condensation. When trying to wope it, sticky gook came off on my papertowel explosing the bottom level.of the dashboard. I went through all the levels all.the way to Corporate Lexus legal in TX as the fumes were making me sick. I am a senior citizens who was not planning on buying another vehicle as I drive very little. After 4 months with no help from Lexus having symptoms of anxiety, confusion, headache and extreme fatigue, I pushed myself to go drive to dealership which was s lot further than I was comfortable driving thr car in that condition. I told them I did not want another Toyota or Lexus so Itraded it in for a larger used vehicle than so I did not gave to drive the Lexus home. I was feeling even worse after the ride yhere and had developed a nagging little cough that does not go away. I also googled my symptoms which sound like Neuroinflammation that could be associated woth a melting dashboard. This has been a horrible experienced for me all around. I have plenty of documentation with Toyota/Lexus.

Developed a fuel leak at the tank that has previously been exactly described as a recall on the exact year make and model of this vehicle however, when entering my VIN it does not show my VIN number as being affected. I feel there has been a mistake on the Vin number range. However, Lexus refuses to handle the issue under the recall since the VIN number does not trigger as such.

I have a stick dashboard and it’s impairing my vision to see out of front windshield. Lexus did have a recall, but it expired. However, I’m still in danger while driving because of glare.

I had a head on collision with a light pole and the airbags did not deploy. The vehicle was inspected by aProgressive insurance claims adjuster and they claimed the vehicle a total loss. They kept the vehicle. There were no warning lights or anything. The vehicle had been taken into a North Park Lexus dealership after a defective airbag recall to be serviced in 2018.

Exterior driver's door mirror failure. The mirror is insecure, loose, unstable, not secured to the door, and rotates freely on its own. This condition makes it impossible and dangerous for the vehicle's driver to observe any vehicle approaching from the rear, left of the driver's side. The mirror is not secured to the vehicle's driver's door and spins freely. The driver cannot observe any approaching vehicles when pulling out from a parallel parking spot. This condition is this vehicle's "2nd" such incident. Previously, this identical situation happened to the mirror mounted on the passenger side door about 2 years earlier. The maintenance record is on file at the dealership. I paid the Chatham Lexus Dealership approximately $1000.00 to correct this.

My car experienced sudden unintended acceleration. I was at a stop light preparing to turn right when my car accelerated of its own accord crashing into the vehicle in front of me. My foot was firmly on the brake, but I had lost control over the vehicle. Whatever electrical defect I experienced, it was sufficient to rev the engine by itself and override the braking system enough that the vehicle advanced forward in an out-of-control manner. It was unintended, unexpected and beyond my ability to control. Failing to recognize the braking system, my vehicle collided into the vehicle a second time. Because my foot was on the brake and my vehicle still advanced forward, I initially thought I had been hit from behind. However, the erratic RPM behavior and the vehicle's continued acceleration while braking confirmed I was no longer in control of the vehicle. Acting promptly, I immediately took the gear shifter out of drive and put into neutral. It was then and only then that I regained control of the vehicle: it stopped accelerating, stopped revving of its own accord and began responding to the braking system. Please note: my foot was not on the gas pedal, for as soon as I took it out of drive, the RPM returned to normal (i.e. the erratic behavior indicated by the tachometer's RPM, stopped). Had my foot been on the gas pedal instead of the brake pedal, the revving would have continued to behave as before; but it did not. (I do not have an all-weather floor mat. It is neither here nor there, because in the event that I did have one, you would expect the RPM behavior to continue when put into neutral; but again, all behavior returned to normal when the vehicle was put in neutral.) Though I am sympathetic to those that panic in a moment of distress, I was of a present enough mind to know what was happening. An electrical engineer with intimate knowledge of the computer system for this vehicle would be the best to assess what went wrong from a technical perspective.

From time to time as im driving to either speed up or slow down, my car has no power and then within 2-3 seconds it hits hard back into gear. I researched it on line about other lexus and it stated that the problem is in the computer and it has a glitches in the system that needs to be reset/cleared , there are times when it hits so hard that it feels like you have been rear-ended and hurts your back and neck . This is very dangerous and should be fixed by lexus at lexus expense, thank you
