| Description of the problem | On my 2005 sienna xle limited awd, i have noticed at 50+ miles an hour interstate or even downhill) that the car feels like there is excessive rolling resistance, and if i don;t accelerate, very soon it downshifts (have noticed this even on a downhill slope at 45 miles a hour). Service advisor said all toyota cars as designed to downshift as soon as you take your foot from the pedal (something which sounds very strange to me, since i'm driving other makes and models as well). Seems the transmission is not tuned well. On a separate matter, i noticed several times that the car hesitates to accelerate for a few seconds when i push the accelerator a bit harder at very low speeds, such as when i need to merge into heavy traffic from a side road. It also happened when i needed to change the lanes from a very slow moving lane to one where i needed to accelerate rapidly. Again, something feels wrong about the transmission. *nm |
