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.

Received recall notice stating #14299 ignition key rotation was an issue. Stated service had not been completed. I had installed and paid for a complete new ignition unit earlier this spring at a cost of $400.oo plus. I am not happy to know the old unit needed recall, and further that my dealer never notified the manufacturer. I believe I have a refund due at this time. Please reply as soon as possible.

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.

The daytime running lights and front turn signal light sockets in both headlamps have burnt contacts. I took my 2008 Cadillac Dts to the dealer to have the bulbs replaced as my turn signals weren't working. They replaced the bulbs. Two days later they quit working again. I took the car back and they checked it again and informed me that the lamp sockets were burnt and that I would have to replace the entire headlamp assembly because there wasn't a replacement socket available. The cost was going to be approximately $1000 each with labor. I believe this a safety issue and Cadillac should either provide a replacement socket or cover a part of the part and labor. Right now I have the sockets temporarily repaired with paper clips and aluminum foil because on social security I can't afford their cost to fix but I won't drive on the road with no front turn signals and endanger other folks on the road.

Took my vehicle in for safety recall 14299 nothing was done to the switch they just put something on the key and 2 small key rings and told me that nothing else was to be put on the key ring. In my opinion the repair was not done what is stopping the key switch from shutting off as a mechanic nothing was done.

GM recall 14299/NHTSA recall 14V355000 the GM fix for this faulty ignition switch is to install a smaller (13mm) key ring and small inserts on the ignition keys to prevent installing any other things on the key ring. This is not a fix for a faulty ignition switch, but a means to circumvent the problem! I find it extremely difficult to believe that your organization would rubber stamp this shoddy circumvention of the real problem! how many vehicle accidents are you and GM willing to allow before fixing the problem properly? rest assured, my attorney has a copy of this complaint and will take the appropriate action should my vehicle malfunction!

Received notice of GM recall 14299 on 8/18/14. Furious that the parts to remedy this problem are said to be unavailable and no date - or even an expected date - for their availability is given in the letter received. GM has known of this problem literally for years now and I don't appreciate the fact that there are no parts to provide an immediate remedy or an anticipated date for its resolution. Totally unconscionable! meanwhile, owners are expected to use only their ignition key (no other implements are to be on the key ring - such as those for self-defense or convenience) to obviate GM's safety lapse for an undetermined length of time that will be at the convenience of GM, not their customers. Additionally, since there has been media coverage of this particular problem for years, why am I only now receiving notice that my car is involved in this recall?

I started to smell smoke in the car, I shut the engine, the smoke was coming from under the back seat. I removed the back seat, and smelled the fuse box, and opened the fuse box cover, and I found that two relays were very hot, and one of them was burned, and melted all the way into the bottom of the whole fuse box block. I had the whole fuse block replaced the part alone was $225.71 plus installation. A year later same exact thing happened, I went to the dealer, and I was told that there is no recall on this fuse block. So I guess I have to do this all over again if I want to drive this vehicle.
