I BOUGHT THIS H3 HUMMER USED AND IT RAN GOOD UNTIL LAST YEAR. IT WOULD NOT START AT DIFFERENT TIMES BUT AFTER YOU WAITED 10 MINUTES, IT WOULD START. WE JUST PAID 1300.00 TO HAVE THE FUEL PUMP REPLACED LAST WEEK. NOW IT WON'T START AGAIN. I HAVE SEEN MANY COMPLAINTS ON THIS AND THERE SHOULD BE A RECALL ON THIS PROBLEM.

THE H3 WILL NOT START. DASH SCREEN KEEPS SHOWING THE PASSLOCK ACTIVATED AND WON'T TURN OFF. COMPUTER THINKS THE H3 IS BEING STOLEN. I HAVE TRIED TO RESET AND NO LUCK.

ENGINE IS TURNING OVER AND ELECTRICAL SYSTEMS LIGHT UP, BUT SOUNDS LIKE FUEL IS NOT GETTING INTO THE FUEL PUMP AGAIN. AFTER DOING SOME RESEARCH, FINDING OTHERS HAVING THE SAME PROBLEM. RECOMMENDED PROCEDURE IS TO WAIT 10 MIN, STILL NO LUCK. WAITING 15…

I was driving the vehicle at a normal rate of speed and stopped at a traffic light getting ready to change. I applied the brakes and when doing so, I heard some horrible noises and felt certain that parts had fallen out of the car. I knew something was immediately seriously wrong. I put the car in park (but it was effort and a grinding noise to put it in park) and stepped out to look under the car. No parts were on the ground, but something was leaking out of the bottom of the car. I got back in and put the car in drive to move it from the road…
