2007 Odyssey VSA, brake, ABS lights on while driving

I have been Toyota driver and this is my first Honda vichicle. but it turned out to be trouble for me.
I just got this 2007 Odyssey in October. ever since then, it randomly turns on VSA, Brake, ABS lights on while driving (particularly on highway).
one example, I was driving on highway, then suddendly ABS, brake, VSA, and VSA indicate (!) all turned on. so I got off highway and restarted engine. everything was back to normal (no lights). I checked on brake fluid. it was full and there was no leaking.
another day I was drving on a local street, then VSA, brake went on. so I stoped engine and restarted. brake light went off. but VSA light stayed on. then I parked it and went for dinner. after that, it went off.

i went to dealer. they said they were not able to detect any problem because they couldn't duplicate the issue.
this is drivng me nuts given that I bougt this brand new car of peace of mind.

has anyone had any similar problems?
what options do i have if dealer just can't 'detect' or 'duplicate' the issue?
