My car experienced a stall while driving, first time it ever happened, i coasted to a stop, restarted my car no problem. called my cadillac mechanic friend who does work from his house on the side from working at the caddy dealer. he said if it happens again let him know we will check the code. so next day it happened again, but only with the flashing lights some of you members i remember complaining about this... so he pulled the code, he changed a lot of shit on my car...to see if this eliminates the one problem he hopes it wouldnt be....turns out its the brake module he needs to replace, and thats the one problem he hadent hoped it would be...it will be about 600 to fix i cant imagine what the dealer would charge.
