I have noted an agressive acceleration in both my cars under the same
circumstances, but it is NOT an uncontrollable runaway acceleration.
It is just the nature of the beast.

I guess Toyota could reprogram that situation, but in my case it is not
a problem at all.

That is something other than whats been happening and may be normal,
depending on how the cruise control is used

Apparently other Toyota owns felt that way as well, until it happened to
their Toyota

I liked the Buick Reveria I owned way back. There was no minimum speed at
which cruse could be engaged. If I had it set a say 30MPH and came to a
traffic light, all I needed to do was hit resume and it would accelerate
smoothly back up to the set speed.

Dunno.. Unless the cruise is drastically increasing the speed
to a level over what the cruise is set at, sounds fairly normal.
I don't know about the new versions, but I know my 05 Corolla
is very aggressive at regaining speed if it drops below the set speed.
So if you had it set at say, 70mph, and then disconnected it and
let the speed drop to say 60 and then reset it, it will punch the
throttle pretty good to get back up to speed. In the case of the
Corolla, it will often downshift. Many times two gears down.
I'll see this if I'm going up a grade and the speed keeps dropping
off. There is actually no need to downshift at all in most cases,
but the programming tells it to do it. And this programming is
coming from the aggressive cruise control, not the throttle per say.
I bet the downshifting is why he saw the drastic rpm increase.

If I go up a hill and it downshifts, if I disconnect the cruise, it
instantly shifts back to high gear. This quirk annoys the heck
out of me, but I do not consider it a defect. It's just the way they
programmed it. My cure is to manually apply the gas going up
steep grades and override the cruise. That way it doesn't slow
down below set speed and want to punch it and downshift.

So really that story means nothing to me, unless the guy can
state that the speed runs way past the set speed. There is
no mention of the final speed it gets up to. When normal, it
will quickly up shift and throttle down quite near the set speed.
It will not drastically overrun it.
But with a resume like he's talking about, it's quite normal
to feel like speed racer just sat in the seat on your lap. :/
Or at least I know it is on some models like mine..
It's not a defect. It's just overly aggressive at throttling up
when it senses too low a speed, because it was too slow at
slowly throttling up to keep the same speed on the grade like it
really should be doing.

Now if his is taking off and wanting to do 100 mph, yep,
Houston we would have a problem.. :/
