Momentary Cut In Acceleration

[braindead]

Twice in the past six months I've been accelerating hard and when I get to 60/70 the car has stopped accelerating for about a second. This is the speed at which I would expect the final drive ratio to change - you can always feel it happen but it's more of a gentle kick. This isn't...it seems to last an age.

On both occasions I tried to reproduce to effect by accelerating hard from well below 60 and it did the ratio change as expected without the delay.

I'm wondering if it's occurred after weeks of sub 60mph driving and something in the drive train is a bit "sticky" . It would fit with the pattern.

Anyone else noticed this on a GS450h?

I've not noticed any flat spots in our 450, and i've been doing a lot of 50 to 70... perhaps these is a software update or something needed? I'll keep checking, but so i can check the same. are you in normal drive and normal suspension settings?

I do find the same thing sometimes, but it hasn't happened for a while. It seems to me to occur after leaving town at low speeds (sub 40) then accelerating gently from the roundabout to the speed limit change followed by hard acceleration.

I'll will keep observing.
