Reference recall 14V755 Nov 25, 2014, I experienced this problem in February 2014 while driving home at night on a back road with little traffic. I was going 45 mph and suddenly pitch black. I thought quickly thought to hit my high beams. After spending money, replaced the relay and the following July it completely melted down, burning up my fuse box and several wires in the harness while parked in my driveway without keys in it. I happened to walk out and smelled it burning. I was able to remove the positive battery terminal. Clearly it was the (hdm) headlight relay stated in this recall. (photo attached).I've spent about $1500 in repairs. There are many blogs with the same problem and burned up a lot worse than mine. It seems to be a regular problem ending with fires in the fuse box.

While driving, the car suddenly loses power. "starting disabled due to electronic throttle control" message shows, then reduced power message. This happens while going full speed (interstate) stopped at redlight, reduced speed making a turn, or in park idling. First dealer said nothing wrong that they could find. Second said to replace throttle body and brake switch. Both of these were replaced and it still will stop. Called support, and all they would say is to take it for diagnostics, even though it's been done. Twice.

The ignition switch failed on 12/24/2015 while I was driving on the East bound I-80 in California. I was not able to use the brakes or steering and rear ended the truck in front of me at about 40 miles per hour. The air bags did not deploy and I was bale to start the car and drive off the highway. Surprisingly I had the ignition switch recall for my keys mailed to me in August of 2015 and had the Cadillac dealer in reno nv modify my key and key ring on 10/31/2015. But I don't think the modification was ever performed since the ignition switch failed two months later....updated 02/02/16......updated 05-10-16...updated 07/13/16

Beginning approximately the end of March, while driving at night, both of my low beam headlights have gone out at the same time. They came right back on at that time so I thought I hit a switch. Sometime in may it happened again, but the lights would not go back on so I used my hi beams. The low beams worked fine in the morning. This has happened about 3 more times since then and is becoming more frequent. Last night on July 23, it happened again on a dark, curvy road and I almost ran off the road. This morning, they work fine again. I called the dealer and they said there was no recall on this. I am surprised as this is a serious safety issue. I need to get it repaired, but since it is an intermittent problem, I suspect the dealer will not be able to find the root cause or fix the problem.

The transmission shifter is not transmitting an electrical signal to allow the ignition key to turn to the off position and will only turn as far as the acc (accessory) position so that the battery continues to drain and die leaving me stranded in the night and on the road and in danger often. A locksmith said continuing to turn and pull on the key trying to remove it myself could result in serious neck and head injury if the airbag where to deploy while I am trying to get the key unstuck. I took to Chevrolet dealer and he said he would need a recall code/number to accept my vehicle for repair with this issue.

When I got off work I tried to start my car but the battery was dead. The car was jumped off. The car operated fine but the headlights would not shut off to daytime running lights. After driving the car for 10 minutes, you could smell burning electrical component's. after inspecting the relays we found the headlight relay was almost completely melted down. The relay was changed and the car seemed to be working okay.

The car drove fine during the day without any problems. The day was a warm sunny day. I parked the car at church and went inside. 45 min. - 1 hour after parking the care I was asked to go outside. When I got outside I was told my car was smoking with the lights flashing and wipers running. Upon opening the hood I found the fuse box was completely melted through with the wireharness melted through where it plugs into the fuse box. The wireharness across the engine was also melted across the top of the engine.

When leaving a friends house our low beam headlamps failed to illuminate. I tried to manually make them come on and they still would not illuminate. I still had high beams, tail lamps, and side marker lamps. I turned on my fog lamps to make it home with lighting to the front.

I drove my Pontiac to cvs and returned home without any problem. Parked the car as usual and went into my home. About 15 minutes later, my neighbor came to my door to alert me that my car was on fire. She stated that she had already called 911 so I jumped into action and got my water hose to try and contain the fire. There were flames coming from under the hood.the car burned for around 10 minutes before the fire department showed up. The fire department had to use the jaws of life to open the hood. There was no recent work done to the car and it was running normal. There was no indication that this was going to happen. The car has been deemed a total loss by allstate.
