Toyota said it was still working with officials with the National Highway Traffic Safety Administration to find a remedy to fix the problem and said owners could be notified about the recall as early as next week. Toyota spokesman Irv Miller said until the company finds a fix, owners should take out the removable floor mat on the driver’s side and not replace it.

“A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop a vehicle, which could cause a crash, serious injury or death,” Miller said.

Toyota and the government issued separate warnings to owners of Toyota and Lexus vehicles about the safety problems tied to the floor mats.

“This is an urgent matter,” Transportation Secretary Ray LaHood said in a statement. “For everyone’s sake, we strongly urge owners of these vehicles to remove mats or other obstacles that could lead to unintended acceleration.”

The recall will affect 2007-2010 model year Toyota Camry, 2005-2010 Toyota Avalon, 2004-2009 Toyota Prius, 2005-2010 Tacoma, 2007-2010 Toyota Tundra, 2007-2010 Lexus ES350 and 2006-2010 Lexus IS250 and IS350.

Toyota’s previously largest U.S. recall was about 900,000 vehicles in 2005 to fix a steering issue. The company declined to say how many complaints it had received about the accelerator issue.

NHTSA said it had received reports of 102 incidents in which the accelerator may have become stuck on the Toyota vehicles involved.

The Japanese automaker warned owners that if they think their vehicle is accelerating out of control, they should check to see whether their floor mat is under the pedal. If a driver can’t remove the floor mat, Toyota advises drivers to step on the brake pedal with both feet until the vehicle slows and then try to put it into neutral and switch the ignition to accessory power.

For vehicles with engine start/stop buttons, Toyota said the engine can be shut off by holding the button down for three seconds.

The safety concern was prompted by a fiery crash in California that killed four family members in August near San Diego. The crash killed California Highway Patrol Officer Mark Saylor, 45, and three others on State Route 125 in Santee.

The runaway car was traveling at more than 120 mph when it hit a sport utility vehicle, launched off an embankment, rolled several times and burst into flames.

In mid-September, Toyota ordered 1,400 Toyota and Lexus dealers nationwide to ensure that each new, used and loaner vehicles had the proper floor mats and that the mats were properly secured.

In September 2007, Toyota recalled an accessory all-weather floor mat sold for use in some 2007 and 2008 model year Lexus ES 350 and Toyota Camry vehicles because of similar problems.

I personally have both the cloth mat and the weather mat on top and both are hooked together. The hook doesn’t move with both of them together. It states not to do this but when the hook doesn’t move the mat won’t slide off. I have both mats on my 07 Tundra and 07 Prius now for over 2 years with not 1 issue with that. I think what they have here is a Walmart brand doing this problem or an unattentitive driver. The unattentitive driver never looked at the mats before they got in to even see the hooks are even there.

On the road the bouncing bed came to mind, so I started watching them. I saw tons of Tundras with all kinds of configurations. I also took note of what kind of road I was driving on to determine weather it was affecting the bounce. I dilligently looked to find a bouncing bed, but never saw anything close to a bounce on any of them. I thought I was going to get back without a single bed bounce, and then about an hour south of Wichita…

Ironically it was on a white 5.7 DC. What caught me even more by surpise is that it was towing a trailer with about a 24′ sailboat on it. The road was one of the smoothest I had driven on the whole trip. I was truely surprised to see the bed gaps expand and contract. From what the owners have written a load makes the bounce go away or at least minimizes it.

I must have seen about 50+ Tundras and saw only 1 with the issue. Just thought you guys might find this interesting.

BTW..that F150 sure did travel good…just kidding….actually I have spent more time here than on the F150online website.
