My 2010 Tacoma, while sitting at a stop light, suddenly surges as if somebody hit the gas or slammed me in the rear. It hasnt pushed me beyond my brakes but it is very disturbing. I reported this to the Toyota dealer and they said they couldnt reproduce it. It doesnt happen with any regularity, it just happens out of the blue. Additionally, when you go to very low speeds and make a sharp turn the rpms jump to about 3,000 and then it feels like the transmission kicks in. This was also reported to the dealer who said it was by design but if it is it is poor design.
2010 Toyota Tacoma double cab pre-runner, I have experience a sudden jerk (like other car has hit me on the rear) while I was stopped and the brake was pressed while waiting at the traffic light. It happened to me three time for five days after I brought my truck to the dealership to repair this problem, which they said that there is no problem and it is just because the Tacoma has a sequential type of transmission. .
The vehicle surges unexpectedly. One or more times a day, depending on travel needs, I experience surges both at complete stops and when accelerating. Depressing the accelerator pedal from a stop or roll includes a "delay" in response from the vehicle, then the unexpected surge is noticed. Generally, a small amount of pressure on the pedal does not yield a desired acceleration effect, instead a "wait and go" effect is experienced. Several times, this delay has caused near misses in terms of accidents. Expecting the vehicle to respond to accelerator pressure but not getting acceleration is considered hazardous. Surging forward violently when at a complete stop is another concern. With the brakes completely depressed, the vehicle will surge forward at most traffic lights or during stop and go traffic. This vehicle was brought to the dealer a week after purchase with my concerning of shifting and sometime erratic behavior. The dealership did little more than take a short test drive with me (no diagnostics, no formal or mechanical evaluation), and tell me nothing was wrong with the truck. The truck had less than 1000 miles on it, now with 2600 miles, the problems persist.
