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 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.

2005 toyota tundra double cab, v8. When cold engine idles higher than what I would consider normal. When stopped at stop lights and the like in normal driving the transmission will jump or kick sometimes causing vehicle to move forward...especially when A/C is on. When cruise control on it will downshift to passing gear and accelerate way more than normal, tach goes to near redline, when encounter the slightest of grades...also happens when cruise is disengaged to slow and then resumed. Transmission shifts improperly when slowing down such as when slowing to make a turn...when apply the gas going through the turn the engine will rev before slipping back into gear. I began noticing these things immediately after purchasing vehicle in nov. '05.

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!

The cruise control on my 2005 toyota tundra downshifts the engine on the slightest incline. It jumps from approximately 2100 RPM's to over 3500 RPM's. This causes the vehicle to loose traction on just a wet pavement, not raining just wet last visit to the dealer this was part of the issues I wanted them to look into. The only thing I got was "that's just the way they work". This is a definite safety issue and needs some attention real soon. Toyota which owns suburau has the same transmission problem as this tundra, I had one of those also that did the very same thing. Not only a safety issue, but it also causes much more wear and tear on the parts. There is also issues with the way the transmission shifts, sometimes it does and other times it don't and always unpredictable. The converter lockup locks up at the slowest speeds ,anywhere from 20 to 55 MPH. In city traffic this causes you to downshift constantly and once you do you have to get right back off the accelerator and or get on the brake. It's crazy to be "that's just the way they work".

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.
