My SES light came on after 30 mins of driving home from work in this crazy storm we had lastnight. After reading posts online, I assume that my car is in limp mode because the engine will not rev high at all. My only question is if i have to go to the dealer to have it reset and since the roads still suck. Will it come on again? I drive 45 mins on a dry day.

 

Figure out what code its firing. See if clearing it helps. If not, try disconnecting the battery and reconnecting it...
