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.

Have been smelling gas after fill ups for several months. Each time I fill it and park it in my garage it fills with gas fumes that could explode and kill someone unaware. Odor leaves after driving 30 miles or so. Got check engine light and O'reily auto parts check and said it showed fuel issues. Took car to my GM dealer and they say need a new gas tank, a new gas cap and new evaporative lines because I have a leaking gas tank leaking at or near filling area, and gas cap is not good and lines are leaking according to a "smoke" test. Repairs are $2,800. I am 75 yrs old and have never had a gas tank leak at the "neck" area after owning some 40 different cars, some of them very old. I believe this may be a factory defective product and a dangerous one at that. It is currently at the dealer and tomorrow I will pay $175 for the smoke test but I cannot afford to fix it so I will only fill it to the 12 gallon point instead of full. Please advise if there is a recall or perhaps other Cadillac Dts owners with this or a similar problem

I was backing my car out of my driveway, as I backed onto the road, the car suddenly quit running. I tried restarting it, but it was completely dead...I had to call a tow truck and the car was taken to a local Cadillac dealer..when I went to the dealer the following day, I was informed that the fuse box under the rear seat had shorted out...I was told there was not any recalls on the fuse box that they new of..I was told a new fuse box and associated costs would run $716, I had no choice but to have the repair work done.. the fuse box cost alone was over $400. My car had 48,000 miles on it when this occurred..I have had many cars in my time and never had a fuse box short out..if this occurred on a highway, I would have lost P/S, ,P/B ect. And the results could have been fatal...GM is aware of this, but to myknowledge has not issued a recall.incidently, the dealership had fuse boxes in stock......
