Yep...Toyota was able to replicate the sideways slide that prompted Consumer Reports to label the GX 460 a safety risk last week. And their engineers formulated a software update to prompt the stability control to step in sooner.

Toyota Japan issued a news release with a lot more in the way of hard facts:


TMC Announces Remedy for Vehicle Stability Control in Lexus GX 460 and Toyota Land Cruiser Prado


Toyota City, Japan—Toyota Motor Corporation (TMC) announces its remedy for the problem concerning the Vehicle Stability Control (VSC) program in its Lexus GX 460 and certain Land Cruiser Prado vehicles.

In circumstances in which advanced driving skills are required, such as when a driver of the involved vehicle sharply turns the steering wheel in high-speed conditions, or when the driver negotiates a curve at excessive speeds, the vehicle could slide sideways, due to the insufficient activation of the VSC.

The following conditions combine to cause the problem:

- In the GX 460 and Land Cruiser Prado, heavy components, such as the fuel tank, are located on the left side, and in left-hand drive versions, the left side is made even heavier because of the presence of the driver.

- For vehicles with certain tires (on 18-inch wheels) and equipped with the Kinetic Dynamic Suspension System (KDSS*) and VSC, the activation of the VSC may not be sufficient in certain circumstances due to the setting of the VSC program.

- Circumstances may require advanced driving skills, such as sharp turns of the steering wheel in high-speed conditions or negotiating a curve to the right at excessive speeds.

As a remedy, Toyota will update the VSC program to enhance the effectiveness of the VSC so that the risk of the vehicle sliding, even to the point that it is almost sideways, will be reduced.

Vehicles involved are as follows:

- GX 460: Approx. 13,000 units in total Approx. 9,400 units in the United States, approx. 1,000 units in Russia, approx 1,000 units in Oman

- Land Cruiser Prado: Approx. 21,000 units in total (only left-hand drive vehicles with KDSS and VSC) Approx. 4,400 units in Oman, approx. 4,000 units in Russia, approx. 1,500 units in the United Arab Emirates. No right-hand drive units have this problem.

In total, approximately 34,000 units worldwide are involved. In North America, Toyota Motor Sales, U.S.A., Inc. (TMS) and Toyota Canada Inc. (TCI) each announced a voluntary recall on April 19 (local time). As for other regions and countries involved, such as in Europe and the Middle East, TMC will work to implement similar measures as soon as possible.

Parts to reinforce the pedals are already being shipped for use by dealers, and dealer training is under way. Many Toyota dealers will work extended hours to complete the recall campaign as quickly and conveniently as possible, some even staying open 24 hours a day. The company has also taken the unprecedented action of stopping production of affected vehicles for the week of February 1.

“Nothing is more important to us than the safety and reliability of the vehicles our customers drive,” said Jim Lentz, president and Chief Operating Officer, TMS. “We deeply regret the concern that our recalls have caused for our customers and we are doing everything we can – as fast as we can – to make things right. Stopping production is never an easy decision, but we are 100% confident it was the right decision. We know what’s causing the sticking accelerator pedals, and we know what we have to do to fix it. We also know it is most important to fix this problem in the cars on the road.”

Lentz added: “We are focused on making this recall as simple and trouble-free as possible, and will work day and night with our dealers to fix recalled vehicles quickly. We want to demonstrate that our commitment to safety is as high as ever and that our commitment to our customers is unwavering.” On January 21, Toyota announced its intention to recall approximately 2.3 million select Toyota Division vehicles equipped with a specific pedal assembly and suspended sales of the eight models involved in the recall on January 26. Toyota vehicles affected by the recall include:

• Certain 2009-2010 RAV4

• Certain 2009-2010 Corolla

• 2009-2010 Matrix

• 2005-2010 Avalon

• Certain 2007-2010 Camry

• Certain 2010 Highlander

• 2007-2010 Tundra

• 2008-2010 Sequoia

No Lexus Division or Scion vehicles are affected by these actions. Also not affected are Toyota Prius, Tacoma, Sienna, Venza, Solara, Yaris, 4Runner, FJ Cruiser, Land Cruiser, Highlander hybrids and certain Camry models, including Camry hybrids, all of which remain for sale. Further, Camry, RAV4, Corolla and Highlander vehicles with Vehicle Identification Numbers (VIN) that begin with “J” are not affected by the accelerator pedal recall. In the event that a driver experiences an accelerator pedal that sticks in a partial open throttle position or returns slowly to idle position, the vehicle can be controlled with firm and steady application of the brakes.

The brakes should not be pumped repeatedly because it could deplete vacuum assist, requiring stronger brake pedal pressure. The vehicle should be driven to the nearest safe location, the engine shut off and a Toyota dealer contacted for assistance.

How Toyota Will Fix Recalled Vehicles

Toyota has pinpointed the issue that could, on rare occasions, cause accelerator pedals in recalled vehicles to stick in a partially open position. The issue involves a friction device in the pedal designed to provide the proper “feel” by adding resistance and making the pedal steady and stable. The device includes a shoe that rubs against an adjoining surface during normal pedal operation.

Due to the materials used, wear and environmental conditions, these surfaces may, over time, begin to stick and release instead of operating smoothly. In some cases, friction could increase to a point that the pedal is slow to return to the idle position or, in rare cases, the pedal sticks, leaving the throttle partially open. Toyota’s solution for current owners is both effective and simple. A precision-cut steel reinforcement bar will be installed into the assembly that will reduce the surface tension between the friction shoe and the adjoining surface.

With this reinforcement in place, the excess friction that can cause the pedal to stick is eliminated. The company has confirmed the effectiveness of the newly reinforced pedals through rigorous testing on pedal assemblies that had previously shown a tendency to stick. Separately from the recall for sticking accelerator pedals, Toyota is in the process of recalling vehicles to address rare instances in which floor mats have trapped the accelerator pedal in certain Toyota and Lexus models (announced November 25, 2009), and is already notifying customers about how it will fix this issue. In the case of vehicles covered by both recalls, it is Toyota’s intention to remedy both at the same time.
