i have to do more testing, but the other day while making a left turn the car seemed to just lose power, and then pick back up again. i was stopped, and went to accelerate while turning into a left turn (a wide left turn, but in the end of the turn i had to put more wheel into it to keep in the lane, etc), at the moment i put more wheel into it the car just went limp, and then resumed.
so my question is, does either stability control or traction control (on this vehicle) cause the engine to reduce power, or cause the transmission to de-couple during certain conditions?? i didnt notice rpm's on the gauge, but i didnt hear a rev. my foot was steady on the gas pedal.
VSC can apply individual wheel brakes or reduce power.
You just might have pushed it too hard and Mr Toyota came to your aid.
thats the issue, it wasnt a hard push into the turn, nothing i would expect to cause the engine to reduce power. i would consider it to be dangerous considering the turn i was taking. if i needed to really jam the gas to avoid a accident i would not have been able to at that moment. i'd say it was on the order of 1+ sec but less than 2sec, which can make a diff in some cases.....
if it was VSC then it is way too sensitive, perhaps dangerous.

by de-couple i assume you mean stop driving both wheels? as far as i know, and unless youve purchased and installed the TRD limited slip diff, the transmission is already "de-coupled", so if you did a burn out for instance, only the wheel with less traction would spin. I dont think this is the case with your car.
My bet is that while making the turn the variance in wheel speed bewteen outside and inside wheels was too great, causing the car to think you were losing traction, and killing power.
my advice, go play around in an empty parkling lot and try and duplicate this situation. if its easily duplicated, take it to the dealer and have them check it out.

You should try it with and without the Traction control as well.

i will try the same turn w/ and w/o VSC.
my concern is, the turn i took (imo) should not have caused VSC to kick in, and in my case i think its more dangerous to have it do what it did, it was clean dry pavement so i doubt the wheels were slipping that much.
Alas, one more reason to strangle Congress. Really...did they have to force manufacturers to criple our cars with all this mandated technology...just because people drive too fast for the conditions? IMO - VSC and Traction Control are unnecessary.
As for reducing power, I've stupidly taken some pretty hard turns and can't complain. However if one of my turns is too hard and one of the wheels starts to slip, then yeah power will be reduced so that the wheel regains traction Normal operation.

same goes for the new Avatar blue-ray dvd discs. apparently the encryption track has newer protocol than many blue-ray dvd firmware can support, and until the firmware is updated (if it can be) the dvd will not play.
sometimes technology is the enemy to enjoying the purchase. i know my xrs has the VSC off switch, but for cases where wheels do slip beyond my control i like the technology to do its job. in my case no wheels were slipping, but perhaps in the turn the diff in wheel rpm's caused the sensor to kick in, something i was not expecting it to do, etc.
Yeah I've heard many people having this problem before as well including myself its not the TRAC though its the damn VSC that does it... TRAC is actually pretty useful however I hope VSC can go to hell =D

I know this is off topic but I had to say that the Avatar Blu-ray played great on several of my Blu-ray players & looked awesome on my 106" front projector in my theater room!

Zero issues on my PS3...
Oh, and I have not experienced anything like the OP is describing. I have taken some wicked awesome corners that the Wifey got mad at me for taking and NO loss in power
