Parked car and returned to start, engine would turn over but would not start. Replaced the fuel pump and fuel relay. Car cranked and ran. Drove approximately 10 miles car cut off while driving and would not restart . Since we replaced the fuel relay under the seat, we took seat out and went to check the relay to find the fuse box too hot to touch and the smell of burning wires. Disconnected the battery, which is also under the seat to avoid a fire. Had to call wrecker to tow home. This could have been a disaster if we had not acted as soon as we did, because I had two passengers in the back seat that could have been injured.

After being left stranded on the side of a busy highway for several hours and having to walk the last several miles to an important business meeting, I was just hit by a very costly repair bill ($1573.40) on my 2008 Cadillac DTS for what appears to be (based upon my internet research of the issue) a very prevalent problem with this vehicle and many other similarly manufactured GM makes/models, obviously known to GM, caused by an apparent design flaw in fuel pump relay switch located in the rear fuse block panel of the vehicle. The relay overheats to the point of melting, causing irreparable damage to the relay and the fuse block, causing the vehicle to shut down, lose all power steering and braking ability while operating and creating a potential fire hazard inside the vehicle's passenger cabin below the back, passenger seat. After a paying a very costly repair bill out of pocket and fearful that I was now left driving a potential fire trap (my wife now refuses to ride in the vehicle) I contacted GM through assist@cadillac.com and requested that they Immediately issue a voluntary safety recall of this vehicle and all other GM vehicles manufactured with this fuel pump relay and fuse block assembly and provide me with written confirmation to that affect, so that I may return to the servicing dealer and receive a full refund for the $1573.40 repair charges and so that all other owners of GM manufactured vehicles affected by this obvious safety issue will be alerted to the issue. The following is the resolution response that I received from Bryan at assist@cadillac.com:
