Taken car to dealership for computer analysis and was told that the issue was caused by P0420cataylic converter needed to be replaced. I had cataylic converter replaced elsewhere and noticed that wasn't the problem. After doing some research I found that ignition switch is the reason my car stalls while driving. There was a Product Safety Recall (14299) Ignition key rotation and replaced on 10- 8-20 but I'm having the same problem.

You are driving down the road at night and for no reason the headlights go out. You hit the high beams and in a few minutes they go out. Had this car to the dealers at least 4 times and they keep replacing the relay and a month or two later it does the same thing. We have a lot of dark roads here in Ohio and you can be coming into a curve and the lights go out. You can't see a thing. GM claims they don't have a permanent fix for the problem.

I was getting off of work and as I tried to open my car I noticed the remote wasn't work. As I approached my vehicle I smelled something burnt. Figured it was coming from the alley. I noticed my windshield wipers were up. I manually opened the car and it smelled worse of burnt. Noticed that nothing was working inside my vehicle. I call security to come and help me and as we open the hood it smelled just as bad. We noticed that the fuse box had a melted hole in it. Once it opened several fused were burnt. I have read that several people have had the same issue. I wish U let us upload pictures of this incident. What if while driving my car had caught on fire or something worse could have happened to me or my child. Luckily I was out of my vehicle when this problem occurred. This issue has to be looked at. Now I have to tow my car out of my work garage pay for that and then pay for my vehicle to get fix which we should definitely get reimbursed for it because it's obvious that this is a recurring issue that has not been fixed. It can turn out to be a big law suit against Buick. I had the same issue also with the headlights. I would be driving at night and out of no where my lights would just shut off. Had to replace that also...updated 07/21/15 updated 11/9/2015

A few times the headlights went out. Driving on two lane road once was close to head on accident. I did extensive testing to find that the hdm low beam head light relay manufactured by I think delphi was the problem. I went to auto supply bought the heaviest duty relay I could find. I replaced it an problem was solved. This was back in may of 2014. Then in January 2015 I received recall for this problem. I have contacted G.M. several times. I read where they state if you have paid for the repair they will reimburse owner for the repair. This is black and white plain and simply. I submitted form, receipts, ect. According to their requirement on the recall letter. Does not say I have to wait for several more letters or several years it is on their recall letter.everything they asked for to the standards. While on vacation message to call. After many calls again I was told I have to wait for second recall letter to get reimbursed. She stated I have to take it to dealer. Why so I can have another defective relay installed. Not going to happen just reimburse me for the claim I submitted. I can't return a one year old relay that is far better than their defective relay.they can't figure a remedy out yet. It has been a year now and I am still waiting to be reimbursed because I did not receive the second recall notification because they can't figure this out. Driving a car at night without headlights is not safe and neither is putting one of their defective relays back in it. This relay has been noted to not only fail, but it can melt causing wire harness to melt at a replacement cost to approach $ 2,000 and an possibly an engine fire and that cost very high or vehicle replacement. Just pay me the money owed...
