While driving home around 10 pm with small children; my truck started to surge, became difficult to control, and the gauges did not register anything ( all at 0). this road was in the middle of nowhere and outside a bad area, so i called my husband to come follow me home and i drove home slowly all the while enduring a chugging motion. what is normally a 20 minute trip became an hour and a half trip. when i got home and shut the truck off my husband looked at it thinking that the fuel injectors could be the problem since they had just been recalled and replaced. the truck would not start when he went to restart it and the dash said 'unknown driver". through some research we discovered it is a faulty passlock system. we went through the recommendations and it was fixed. this occurred again today august 18, 2011 while driving and i now can not start my vehicle or have it towed because it can not be put on a truck because everything is locked up tight and can not be unlocked. we changed the batteries in the key fobs to no avail. the windows are stuck open and it is rainy season here. they lights come on and the information center keeps says 'unknown driver." i am now afraid to drive my truck for fear that the next time i will not be able to control it. i have an 18 year old that drives my truck to college and i live in great fear that he will not be able to control the vehicle if it does the same thing while driving it. *tr
