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. This all is related to the vsc system and the software. Please have an investigator call me. I believe that I can easily reproduce this situation in the vehicle. These vehicles are unsafe and toyota needs to address these issues. I don't believe the current recall is addressing the issue!
2005 Toyota Tundra acceleration complaints

I bought a 2003 toyota tundra 4x4 and since I bought it I felt that when I was at a stop light my truck accelerated by itself making a huge noise at the rear end axel I took my truck to a toyota dealer and they said it they find nothing wrong but the problem continued for the 2 years I had the truck then I bough a 2005 tundra also 4x4 and it has the same problem dealer don't do anything to solve my problem sometimes it feels like if someone hits the truck from behind like a sudden jump or push.
Long delay between depressing "drive-by-wire" gas pedal and engine responding. My 2005 toyota tundra has an electronic gas pedal. It's unacceptable behavior may explain some of the current "surging" people are seeing in other toyotas. This is a 100% software problem (I am a electronic engineer). Description: when the engine is at idle, or even worse, when you are decelerating at idle power, and you increase the throttle position of the gas pedal, there is a nearly 1-second delay before the engine responds to the throttle input. If the driver, not sensing any response to throttle, applies more and more throttle during that one second delay, when the engine electronic throttle finally does respond it will immediately go to the highest throttle setting the driver was selecting, causing a huge lurching forward action of the vehicle. For example, if the driver applied throttle in this fashion: 0sec=5% throttle; 0.25sec=10% throttle; 0.5 sec=20% throttle; 0.75sec=35% throttle; 1.0sec=50% throttle. The engine's electronic throttle will respond like this: 0sec=0% throttle; 0.25sec=0% throttle; 0.5 sec=0% throttle; 0.75sec=0% throttle; 1.0sec=50% throttle. Causing the huge lurch at 1.0 second. This has been especially dangerous while changing lanes during stop-and-go traffic in the san francisco bay area. Please note that if I am running at partial power/throttle, this behavior does not happen, and the gas pedal response is proper. Only from idle or decelerating. I have complained numerous times to my toyota dealer, to which the service manager finally replied to me "you think the tundra is bad... You should try driving the sienna! It's worse!" so apparently the folks at toyota know about this and think it's funny. I can demonstrate this defect at any time. I have changed my driving style to protect me from the vehicle's defect.
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.
I have experienced floor mat entanglement issues and uncommanded accelerations with my 2005 tundra double cab. I also have experienced a clunking sound in my brakes/front end when I shift into reverse and then apply the brakes. The dealer has told me all of these issues are normal which according to the recalls for other model years they are clearly not normal. Can the 05 tundras be added to the current recalls and can the brake issue be addressed?
My gas pedal has repeatedly continued to stick in my 2005 toyota tundra. It continues to accelerate, even when my foot is completely off of the gas pedal. I have contacted the dealer and have yet to receive a response.
On february 2, 2010 at about 6:20am while driving my toyota tundra 2005 ,v8 engine,on highway 101 west bound when my vehicle suddenly accelerated on me. I was on lane one between barham ave. & vineland ave when it all happen, making me change lanes at an unsafe speed trying it to control it. I had my foot off the accelerator but it keep going at about 75-80 MPH. There was no cruise control on and I was shocked about the sudden acceleration. The vehicle finally came to normal driving conditions at about 1/4 of a mile from vineland ave.
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.
2005 toyota v8 tundra. Bought new in 2005. When going up hill/incline with cruise control engaged, vehicle dangerously accelerates causing the tires to loose traction on wet or loose surfaces. I noticed this problem shortly after I purchased it. I no longer use the cruise control feature on my tundra. I previously owned a 2000 tundra and the same thing occurred with the cruise control on that vehicle. Seems to be a major/dangerous problem with the tundra.
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.
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.
Tl*- the contact stated that on two separate occasions while driving the 2005 toyota tundra with 28,000 failure mileage the vehicle lurched forward with his foot depressed on the brake pedal. The ignition had to be turned off to stop the vehicle. The vehicle was taken to a dealer, and they found nothing wrong. The contact received recall 05v123000 pertaining to vehicles with dual exhaust.
Cruise control down shifts two gears on slight upgrades. Even elevation changes of less than fifty feet on the highway can trigger this. The sudden unintended application of full throttle acceleration is alarming and dangerous. This surge or power always result in the cruise control surging past the set speed usually by five miles per hour. Depending on terrain this can happen as often as every twenty seconds!
We own "two" 2005 toyota tundra double cabs that are equipped the same. Both of these vehicles exhibit the same saftey issue. The issue: when driving with cruise control "on" at speeds of 70 MPH, on slightly uphill track, the cruise control will command the vehicle to maximum throttle, shifing the transmission into passing gear. This action on the 287 horsepower vehicle, causes the rear tires to break loose on wet roads and can cause loss of control of the vehicle, sending it off the road or into a spin. Both vehicles we own exhibit this behavior and it has been reported to toyota case # 200510040775.
