Pretty confident that you're having that issue because of a Zero Point Calibration not being done after an alignment. I had the exact same issue on my 06 Double Cab. It would about pull me off the road when going through interstate clover leaf sweeping turns - hugely dangerous. I think a lot of non-Toyota shops may not know this calibration needs to be done after an alignment and/or installing a lift kit. I ended up buying a fairly advanced DIY diagnostic tool and was able to perform the ZPC myself in a matter of about 4 minutes. I went from having the issue almost every trip through the interchange to not having it in ~2 years. What a relief!
Been chasing this problem on my 05 DC 4WD Tundra. Toyota Dealer told me all my sensors were working properly and that everything was working as designed. Several zero point calibrations did not solve the issue. I’ve heard all 4 wheel speed sensors should be removed inspected/cleaned and tested with an Oscilloscope to verify working condition as scan tools are too slow to pick it up. Toyota really crapped the bed on this problem and at this point they do not care. I’ve had multiple zero point calibrations done by Toyota as well as alignments and sensors tested and calibrated. Going to try this route and I will report back!
So I have the same system. I’ve had this truck for a few months now haven’t taken it on any long hauls yet. I think I may have experienced this once. My concern rn is that master cylinder you have. Mine is leaking somewhere in that unit, do you know of any rebuild kits. The unit is so expensive
I have this problem with 2006 Tundra quad cab. It does seem to be primarily drivers side but happens turning either direction. Scary as hell. The power cutout issue happens when turning right at an intersection with a slight incline and trying to catch up to the speed of traffic. Truck slows and traffic behind has to brake until my truck recovers and can accelerate again. Curious that subsequent models have the ability to disable VSC.
I have the same issue, but not as bad as yours. I was thinking about doing this same mod to my truck. What happens if you tur the switch to "off" wile driving? There have been many times when I'm on a road without a great place to pull off and I get the VSC engagement and want to turn it off without stopping. I'd assume it would turn off VSC, but to turn it back on would require vehicle restart.

Did you figure out if it was zero point?
Which tool did you buy @bryanhiggins3816
The Toyota dealer here didn’t even know what zero point calibration is

My Sequoia is doing this, thank you for the video. Going to try the ZPC too

Awesome. Any tips on bleeding the brake fluid in this system?

I did this on my 3rd gen and it worked fine and never gave me issues, I just never turned it back on after installing the switch lol
3rd gen 4 runnet
What if u change all the wheel sensors would the be a permanent solution
Thanks for this info
I know that road...lol
