Replying to: user777 (Aug 25, 2006 8:12 am) If the pressure point "used" by your foot to actuate the accelerator pedal is higher up on the pedal then the amount of pressure you need to use to move the pedal will be higher, maybe MUCH higher. Additionally the distance your foot must travel for a given throttle opening would be lessened. Both of those parameters would contribute to the probability of the engine/transaxle ECU "seeing" a QUICK and FAST lift of the accelerator pedal compared to your normal accelerator pedal application/release at a lower position of the pedal. A QUICK and FAST release of the accelerator pedal would be more likely to convey an intent to coast down to a lower speed rather than an intent to enter cruise, perhaps now simply maintain the current speed. I have suggested that those experiencing the delay/hesitation may wish to try simulating my "circuit" by using left foot braking. When you foresee that you might, will, need to accelerate just after a coast down period then try this: As you release the accelerator pedal (QUICKLY and FULLY!), use your left foot to apply the brake just lightly enough to turn on the brake lights. That should, undoubtedly, prevent the engine/transaxle from interpolating your actions as a desire to enter cruise mode and thereby prevent an upshift. With any luck at all it will leave you in the current gear ratio, at least, and may even result in a downshift. |

Replying to: user777 (Aug 25, 2006 8:12 am) But regardless of if I have to stand on my head in order to accommodate this car's glitches and to drive it safely, the fact remains that there is a problem with this car and unsuspecting RAV4 owners should not have to be the ones to deal with it. I plan to follow up by letter with Toyota hq and dealer, and hope to get some response from NHTSA to my ODI. Stay in touch - thanks. |

Replying to: user777 (Aug 20, 2006 10:30 pm) I just got back from a different Toyota dealer I bought the car from. They said it was due to what they called the fly by wire programing in the on board computer. Seems they've had this before. They gave me the 800 Toyota number to call, because there is nothing they can do about it. They also said other vehicles also do it. I hate to say it, but I'm becoming uneasy with this vehicle.

| I have driven my wife's 2006 V6 Limited about 6000 km so far under various driving conditions, both city and highway and have not yet experienced any throttle lag. Vehicle has responded well to passing gear on 2 lane highways, entering intersections from a Stop sign, etc. Feels just like the old fashioned cable system. Whatever the problem is, it is not systemic across the whole vehicle line. | |
