In the manual in the fine print reads:
If indicator does not turn off within a few seconds of starting engine, there may be a
malfunction. Have vehicle inspected by your Scion or Toyota dealer.
Im going to update my OP.

ON most Denso ECU cars, the VSC and TRC will turn off if the ECU is in diagnostic mode (check engine) so that the throttle is more reliable without intervention. THis is normal when the engine has issues.
It has nothing to do with malfunction of the VSC/TRC modules, as it is OFF only because the ECU is throwing a check code.
It does this on my LS430 and Sienna too, when I trigger a code myself. Hasn't happened to my FRS but I am sure it is the same case.
Also, as far as the core cause of what might be happening. There are MANY MANY reported cases of bad/polluted gasoline that causes injection system issues, especially GDI equipped cars. It might not be the car itself but the bad batch of gas. Even a well-known brand like Chevron and Shell, sometimes have stations that have water in the tanks or pollutants like rusty bits or other leaks, that get introduced to the tank. Might want to look into that too, if the check code is related to intake system or injection systems, or something off on the KNK or O2 sensor readings that are causing the light.
My buddy had the said thing happen to him with a 4 months old Toyota Venza GDI 4 Cyl. Intake manifold pressure became abnormal and O2 went off the charts as fuel system got clogged. It was traced to fine particles of rust in the tank and pollutants in the gasoline, which could only have come from a gas station pump. Upon tracing it with fuel station, it turned out that there were 4 other claims at the same station for the same issue...
Toyota normally will not warranty it in that case, and he basically had the gas station and Chevron pay him back for all repairs and rental car costs for the weeks his car was missing at diagnostics. Check the last fuel pump you used and ask for the gas station's fuel supplier and contact. Oil companies are really quick to pay for any damages, as this is a drop in the bucket to them, really... Just in case.
