Vehicle would not start when atvtrain station. Had to leave overnight and had it troubleshot in am. A faulty fuel pump relay was the supposed cause. Changed the relay on a wednesday morning and car was good till saturday afternoon when it stalled out in the middle of route 9 in heavy traffic. At the time my wife and grandson were in the car. I had to push the vehicle off the road luckily into a strip mall with an auto parts store. Removed grandson and car seat from vehicle to access the relay in rear circuit board. Very hot. I went in and got new relay and had to change it in the parking lot. Went straight home to drop off wife and grandson. Went back out to test drive and see if problem was fixed. Worked for a little while and stalled out again. Again relay burning hot. Had son get a new relay and changed it again and brought vehicle home. The check engine light has now come on so I tested vehicle with ibd minister and gave me a p0230 code which is for a bad fuel pump relay which I already know. I am going to call cadillac dealership and have it looked at. I am very surprised that there isn't a recall on this as it is a life and safety hazard.

Vehicle failed to start after being parked overnight. Engine would crank but not fire. Dealer found rear fuse assembly to be in a "melted condition"; fuel pump fuse/relay was charred. Entire fuse assembly required replacement. Dealer could find no cause for problem. My main concern is this assembly is located under the rear passenger seat next to the batteries. The power surge that caused such heat damage could, in my opinion, result in a fire in the vehicle, or at the very least burn anyone sitting in the rear seat compartment of the vehicle.
