Bought my car Sept. 2022.Within the first couple of months I started having intermittent problems that seemed fuel related.After some research I found out my car had a TSB that has been out since 2016. With this knowledge I took the back seat out of my car and the problems all stopped.June of 2023 started having some problems that were sort of similar to what I was experiencing before with some power loss, had vehicle taken to mechanic who diagnosed an interlock system problem.I thought maybe that would fix all my problems and put my back seat back. I travel 4 hours once a month to go see my son and only took my car once on that trip because of not being able to have a back seat.Me thinking the interlock fix was the solve all to my problems I put the back seat in and started my drive to go see my son. 3 hours in stop for gas, try to start my car, cranks won’t start, not getting fuel. Called mechanic who just worked on my car, suggested to check my fuel pump fuse and fuel relay, find my fuel relay is melted. Replace fuel relay and pulled the back seat out, car fires right up no problems. Continue hour drive to see my son, picked up my son so had to put the back seat in. Drive about 7 blocks and stop at Walmart, try to start car and same problems as before. Replace Fuel relay, propped up the back seat around the fuse box trying to still make it safe enough for my son to ride back there, no more problems that trip, propped seat left leaning in the back. August-Was driving down the Highway at 65mph with the cruise on, when all of a sudden my car begins to lose power and proceeds to stall with no warning. Lost complete control of steering and had minimal control breaking, had to coast to a stop with no breaks or steering, lucky was on a straight rural hwy, can’t imagine if I was in the city. Seat had fallen up against fuse box fried fuel relay again and the control module. Take to shop for repair, control module, fuel pump replaced NSB complete all at my expense.

The fuel pump relay keeps getting hot and burning, causing the car to not start or loosing power while driving. Lost power going up a hill and around curve with no place to pull over. Could have been hit when car died in blind spot in road. Looked it up and other people on line are saying it is the seat clips hitting fuse box causing short circuit in fuse box and damaging fuse box. People said they thought it was fuel pump but still had same problem after replacing fuel pump. A lot of upset people on line saying there should have already been recall on this problem. Have had 2 mechanics look at it. Have bought 3 relays. Afraid to drive car if it will start, fear of loosing power in middle of road and getting killed. Not to mention could cause fire since fuse box and battery are under back seat.. Genius engineer, I'll tell you! Don't know if I can ever completely trust this buick again. Never had anything like this happen to any car I've ever owned.Something needs to be done. Recall Recall Recall !!!!!!!!!!!!!!

Rear seat makes contact with top of fuse block cover causing it to push aginst fuel pump relay causing it to overheat and burn out. This relay gets heated to the point that it could present a fire hazard. Due to the heat it generates, it melts the fuse block causing it to have to be replaced. Back seat cannot support weight of an average size person. This problem causes the vehicle to shut down and lose power rendering lose of power steering and power brakes. It is unreprehensible that gm is not made to correct this blatant mistake. This has happened 4 times and the block has been replaced by authorized buic dealer.

Vehicle stalled out on a highway (and at highway speed) and would not restart. Obviously this created a very dangerous condition for me and those around me as I tried to coast over to the shoulder (esp with loss of power steering and brakes). The problem came without any warning, and was determined to have been isolated to the ignition control module. Mileage on the car is only 43k

Lost power while driving 65 MPH on highway which caused power steering and brakes to become hard to use. I took it to mechanic and found that the fuel pump relay had over heated causing the fuel pump to stop. I looked on recalls on the internet and saw where this has become a common problem with these cars and that general motors refuses to issue a recall. This is a very danervous condition and needs to be corrected.

In december of 2013 I was playing music in my vehicle, ( 2008, buick lucerne) the battery got go drained. The thing that surprised me was the fact that after, the battery was drained the ignition ceased. I couldn't move the key up/down or in/out of the ignition. I think that this could have been very serious if I had lost power on the high way. (alternator or battery) when aaa came on the scene as soon as they hooked up my vehicle to a portable battery and, turned it on the key was released immediately.

As I was turning a corner in this vehicle the engine suddenly stopped running. As I was on a lightly traveled street inside a development I was able to stop near the curb. I attempted to restart the car but it would not start. I called for assistance and a flat bed tow truck came after 1 hour. The car was taken to a buick dealer that I normally use. The problem was diagnosed as the failure of the ignition module and 3 ignition coils that were supposedly damaged by the failing ignition coil. I feel that this is a serious problem as the sudden loss of power caused the power steering and braking to cease. If I had been on a busy highway or interstate it could have resulted in an crash as a result of the lack of control of the vehicle. I believe I was fortunate to be on a lightly traveled road inside a development.
