Uncontrollable acceleration: my husband's 2005 Toyota Tundra accelerated at a very high speed while he had his foot on the brake at a stop sign. He had his back pushed up against the seat and pushed as hard as he could on the brake, but the truck took off anyways and he was forced to pull out in front of oncoming traffic. Luckily he wasn't hit. This is the second time this has happened in this truck. In January of 2015 he was backing into our driveway when his truck suddenly accelerated at a very high speed. He put his foot on the brake and the tires kept spinning. He put the transmission into park and after a few more seconds the tires stopped spinning. We contacted Toyota after both occurrences, but they won't help us at all. They say that the truck isn't included in the recall and that it's no longer under warranty.
Unintended acceleration occurred when proceeding through and intersection at about 4:50 pm 01/04/2011. Brakes were applied but the power of the Toyota tunda sr5 v8 engine had enough power to accelerate unintended to approximately 50 MPH even tho the brakes were applied as had hard as it could be applied. The truck centered an oak tree in the blvd approximately 150-200 ft from the intersection. The truck was totaled by my insurance company. Only the driver was in the truck and no other vehicles at the time of the incident. The driver suffered a broken left arm at the elbow which required surgery.
2005 Toyota Tundra, unintended acceleration, my husband was putting it in the driveway and it accelerated into the neighbors fence and drove over a four wheeler if he hadn't put it into park he would have continued into the neighbors house. The acceleration problems have happened quite a few more times though not to this extent, Toyota is refusing to fix or even take a look at the truck, saying it isn't on the recall list so it isn't their fault. The Toyota problem is bigger than they are admitting to and some investigating is necessary, this truck is a danger and they are responsible.
My vehicle suddenly lost power because the plastic fan in the secondary injection system broke and the pieces blew into the exhaust ports and melt, sticking up the exhaust ports. The vehicle doesn't run right and is a safety hazard because of a design problem. Toyota accepts the problem and has extended the vehicle warranties for the 2007-2010 model years, but not for my model year. Repair has cost me over $3,000 for their mistake. It is a safety hazard. It should be recalled.
2005 Toyota Tundra -- 3 times it sped up on its own. Either floormat and/or accelerator. Third time there was a crash, into our retaining wall in our driveway. I tried to get people to pay attention, contacted customer service, etc., at Toyota, no one believed it. Also insurance company said it was driver's fault.
Parking brake engaged partially. Also the engine idled too fast. This combination lead to the vehicle to start moving unexpectedly. As a result my wife injurered her foot and damage to the vehicle was sustained. This could have easily resulted in a fatality.
I have a Toyota Tundra 2005 that has had the throttle drivers updated. I have had at least 6 incidences of uncontrolled acceleration. These incidences occur at slow speed in muddy situations. Depressing the brakes to the floor does not stop the vehicle and I have had several near misses. This occurs in 2 wheel drive and I believe it has to do with the vsc and software. The only way to stop the throttle or unwanted momentum is to throw the vehicle into neutral. Even this does not immediately help. I recommend the ignition key as the quickest way to stop this. Additionally, our company has a newer Tundra that is getting fixed under the recall. This truck has experienced similar situations with other employees driving. Slow speeds in 2 wheel drive, in muddy situations the truck pushes you uncontrollably. I will investigate more once the truck is returned with the recall repairs. …
2005 Toyota Tundra double cab. When stationary on cold start: vehicle produces a loud noise and additional carbon monoxide/exhaust, causing additional danger when starting in a garage. When in motion: truck operates as intended until acceleration is attempted, causing a major safety concern when merging onto highways, driving up an incline, or any other driving situation where the gas application is necessary. When in motion: venting and interior air controls cannot be used based on the amount of exhaust that will spill into the cab of the truck. This is a problem that is widely known to the Toyota community, and to drivers of Toyota tundras in particular. Of note, thousands of messages can be easily accessed in the Toyota message boards (Tundra talk, Toyota nation, tundras.com, Tundra solutions). …
2005 Toyota Tundra experience electronic failure the consumer stated the mechanical or electronic failure caused an accident as well as injuries. The consumer stated all he remembered was exiting the highway in evening traffic when all of a sudden, his vehicle rammed into the vehicle in front of him. The air bags deployed prior to the collision and he had no recollection of being able to brake. He also stated the engine failed in June 2009. The consumer was informed there must have been something wrong with the seams in the radiator. Apparently, it blew out the bottom, which caused the instantaneous loss of the radiator fluid.
Driving at highway speed, with cruise control engaged, and beginning to climb a gentle hill, engine suddenly accelerates at full throttle, and the transmission downshifts two gears. It causes the vehicle to suddenly and rapidly accelerate. Vehicle is very difficult to control on snowy, or rain slick roadways. If following another vehicle that slows on hill, such as a semi tractor-trailer, there is eminent danger of a rear-end collision. This is not an isolated incident, it occurs every time three conditions are met: 1. Cruise control is engaged. 2. Vehicle drives up incline or hill. 3. Highway speed.
