My car won't start if the tilt wheel is not in a certain position. The engine will not start until you put it down in a certain position---which I guess at. After I start it I can adjust the tilt wheel and I have no problem. After stopping and parking the car, I have to get it in the right position to have it start. (yesterday after 3 adjustments, it would not start.) after resting for a few hours, it started.

In nov. Of 2016, my dts was parked and after attempting to start, it would not turn over as if were out of gas. I had to have it towed to repair facility. It was diagnosed and determined that the problem was caused by the fuel pump relay, which had shorted. Further investigation revealed that the actual cause was the fuse block (rear seat). This item is a dealer repair level and should have been recalled since there are several cases of this and other electrical problems involving sudden cut-offs, power steering issues and ignition key problems noted here. My car has experienced all of these.

Fuel pump relay melted replaced rear fuse box and relay tried to start vehicle on 6 june 2016 vehicle would not start at all. Had vehicle towed in to diagnose $81.99 just purchased about 6 months ago. Purchased a warranty but this problem was not covered. I have never had this experience with a vehicle. After extensive reading I find this is a problem with a variety of cadillac vehicles. I had to pay $796.43, parts were $397.51.this should have never happen and could have caused major damage. Since cadillac know this is a problem I feel I should be reimbursed for my suffering and pain. This problem could have resulted in a fire starting in the seat area. I probably would not have known until it was to late.

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.

After parking my car in the garage,approximately 3 weeks later,I went to start my car,but it would not start,it would crank over good ,but would not start. I proceeded with my own assumptions and found a pin(#30)on the fuel pump relay was burnt,I had an electrical diagnosis performed on the wiring and the fuel pump,both passed okay,I was told the fuse block was bad,(which I suspected),which I had previously ordered from the cadillac dealer. On installing the new fuse block,the problem was solved.
