My apologies re treatise, user777, I meant to refer to wwest's posting. I appreciate the responses, but I refuse to do left-foot braking - it's the principal of the thing. Will explore the accelerator sensor angle, though.
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.

This is an interesting observation. The lag/lack of downshift happened to my wife recently. She does keep her foot a bit low on the throttle. I assume you mean center to low on the peddle. Still it has happened to me a couple of times and my foot is placed more center to high on the peddle, so I don't think foot placement is the cause.
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.

On another forum an owner seems to have discovered that not only does left foot braking often prevent the transaxle from upshifting, the prevention of upshifting leaves the transaxle "set", prepared, to accept a downshift command if/when the next accelerator pedal depression is aggressive.

Throttle Lag Issue

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.

I have throttle lag that is intermittent. I am responding now as when the problem goes away it is easy to think that it was in my head. But last night the vehicle was acting fine, accelerating fine; this morning lots of throttle lag. Have had the vehicle a month, and have seen other discussions that talked about vehicle 'learing' how I drive, etc., so was trying to see if that might be the problem; but now with 1800 miles, I am ready to complain. I really dont want to take it to the dealer and get the 'could not duplicate problem' response; but I also dont want to be stuck with a lemon as I only have the first 15k miles to get it replaced. I have submitted a complaint to nhtsa, and have noticed several other complaints of the same problem.

The vehicle could be designed to learn each individual driver's style/technique only if we all agreed to be "chipped". Absent knowing what individual is driving at any given time the vehicle must "relearn" your personal style/technique after each engine start driving session.
Which is the way it works.

I guess we will be able to tell if the parking lot guy or the kids ripped the truck huh? When I get in in the AM, the wheels will come of the ground when I try to tiptoe down the street with the V6?

RAV4 V-6 AWD (2006): I was told by several people that pulling the CPU (computer) for 5-60 seconds (?) will erase the driving profile from active memory and the throttle lag disappears. (You create a new profile by your own driving habits.)
Could somebody send me a comment? -Thanks for your time and cooperation!

I know i've written to Toyota, and have filed a complaint with NHTSA. Toyota says "normal". I've had 4 instances since buying the car in March i deem serious. Scariest was merging in traffic going 50-60 mph from a slow crawl, plenty of room to merge, but literally nothing from Rav when i pushed accelerator pedal, panic, pushed harder, downshifted yada yada. This also was noted as normal. So when the first person dies from trying to merge as i did and gets clobbered in the side by an 18 wheeler, will Toyota also claim "Normal".

toyota recently issued a TSB for improving the shift / operability in the new Camry models. Look in the 2007 Camry Woes forum. perhaps your vehicle is or will be a reflash candidate.
there's speculation that under certain conditions, the Camry was programmed to be too lean (fuel / air ratio).
hard to say, we don't have specifics on the TSB.
maybe you can contact your dealershop or corporate and ask them if the same issues the people with the Camry are experiencing with their transmission / accelerator are being researched by Toyota for the RAV.
perhaps a little research on your part (maybe with the help of someone else if necessary): determine for the Camry I4 if the transmission and ECU/PCM (Engine Control Unit/Powertrain Control Module) are the same part number as in your RAV. that might give reason to be hopeful that the re-flash might improve operability of your ride.
good luck.
