The contact owns a 2008 Cadillac Dts. The contact stated that the vehicle failed to start without warning. The contact independently replaced the relay sensor and the vehicle started. In addition, while driving 55 mph, the engine power and brakes failed, and the steering wheel seized. The vehicle failed to restart. The vehicle was towed to the local dealer (ruddell auto, located on 110 s golf course rd, port angeles, wa, 98362) where it was diagnosed that the relay fuse box and panel melted and need to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 97,000.
On 9/4/15 @ approx 5:45 p. M, vehicle would not start - it acted like there was no fuel getting to the injectors. Three hours later I tried to start the car and it started just fine; took it for a drive around the block w/o any issues. On 9/7/15 the problem resurfaced; I had the car towed to a local mechanic who diagnosed the problem on 9,/8/15, to be a bad fuel pump relay. Car worked fine for one day; on 9/9/15 the problem resurfaced once again - if the car sat off for a couple of hours the problem would go away. I took the car to the Buick GMC dealer and they diagnosed the root cause to be a bad fuse box assembly ($318 part). The fuel pump relay got hot enough to melt the hard plastic of the fuse box assembly, and there are burn marks on the body of the fuel pump relay - I have the old parts and pictures of same. The service rep at the Buick GMC dealer said they have seen this problem on Buick lacrosse. Being that the fuse box is under the rear seat of the car, there is the potential for the car to catch on fire.
