general problems of the 2009 Cadillac DTS

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. 00, I had no choice but to have the repair work done. . The fuse box cost alone was over $400. 00. 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. . . . . .

Fuel relay melted I replaced it and melted again just like my other Cadillac Dts. Both are same year and also same miles. I get that fixed by dealer on 03/26/2013 aand this one at dealer since last Monday. Problem relay boxes is going to be replaced just like the other one. Melting is very dangereous when relay box right under the back seats.

Fuel relay keep burning melting due to overheat. Relay boc is under the back seat I dont think that should be safe and has to be recalled all Dts I have this one happened over two months ago this car was 93325k at that time. My other 09 Cadillac Dts has same problem and in dealer servise right now and that car has 94200 k on it. Both 2009 Dts is it just a quincidance.
