Truck in limp mode. Would not exceed 40mph. Vehicle limped home and towed to dealer. Rodents had chewed electrical wires per Toyota dealer. Upon investigation Toyota began using soy-based wiring in their vehicles instead of petroleum-based and didn't notify their customers. Soy-based products in vehicles have been known to "attract" rodents versus petroleum based products. My 2012 Tundra was still under warranty and Toyota denied said warranty because it wasn't a "failure" of their parts. The vehicle would not accelerate properly or steer properly because the traction control and ecm had failed. This could cause serious injury or harm due to an unsuspecting interruption in speed and traffic flow, as a result of wiring separation occurring while operating the vehicle.

My 2006 Toyota Tundra pickup truck has developed maximum acceleration on five (5) occasions when I made hard accelerations in order to pass other vehicles while also engaging the resume mode of the cruise control. On the first two (2) occasions I applied the brakes heavily with no results and my vehicle continued to accelerate and I was forced to knock the truck out of gear and the engine continued to run a max rpms and I keep pumping the gas pedal until the engine finally slowed. The last time a similar event occurred I had a open highway after passing a slower vehicle so I cut the ignition off and my vehicle slowed down, I turned the ignition back on and my truck went to max acceleration again. The third time I cut the ignition off I heard a thump in the floor board close the gas pedal and the vehicle slowed and operated normally when I turned the ignition back on. I was traveling on a interstate the first two times this problem happened and just avoided hitting other vehicles. On the last occasion I had time to try a different solution. In each event the breaks were not effective at all. On 12/2/10 my Toyota dealers service dept. Checked my truck after I made the above complaint and found no problems. In the past I had raised the issue with the dealers service dept and regional Toyota rep. And was told by both that the 06 Tundra did not have acceleration problems.
