Was driving and vehicle started to stutter, hesitate, then total loss of steering brakes didn't work properly. We were on an over pass during rush hour traffic busy intersection. Finally after about 1 hr we made it to autozone limp mode all the way. Purchased coils X 3, coil ignition module, spark plug wires, spark plugs, camshaft sensor, crankshaft sensor. Then find out it was only a freaking fuse under seat that was burnt and melting away. Not very happy. GM should be held accountable for knowing about this and not offering to fix it.

My Buick has been constantly breaking down and every mechanic has told me the same problem. It is the fuel pump and the fuse box under the seat. I never thought that I would have any problems since buying this car in 2016. But, I have had numerous problems and all I see are recalls on my Buick. Everytime I call in to complain and ask about the recall its always something new and that you guys can't do anything. This was my first purchase for my 21st birthday and I never want a Buick ever again. If there is someone that could help me regarding my fuel pump and fuse box please contact me and maybe you could do better and send me the parts to fix my car. This is ridiculous and I hope someone could contact me right away.

The car was parked and would not start had it towed to a repair shop. The repair shop found the fuel relay had over heated and melted the fuse panel under the back seat. I did some research online and found on repair pal that 105 other people had the same problems. Ebay seller has sold 1264 fuse boxes like this another ebay seller sold 275 fuse blocks for Buick and GM cars. Did some more research found problems back to 1996 2006-2011 Buick Lucerne's had issues.

Fuel pump relay burned out twice. Scorch marks from serious overheat possibly fire on bottom of rear seat. Car stops in middle of road when fuel pump relay appears to pop loose shutting off fuel to engine. Have to press and wiggle relay to restart car. Possible bad connection in fuse box under rear seat.. recommend making manufacturers be prohibited from installing batteries and electrical fuse box from inside passenger compartment. High fire hazard in case of accident!!!

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.

I bought this Buick used a couple of month ago with 87K. I've since driven over 4K miles. I bought this car because it was a big touring car and I needed something reliable and comfortable for longs days on the road. Several hundred miles ago it just wouldn't start in the driveway. Research led me to the fuse board. Checked the fuses and relays found nothing obvious. Car started up a few minutes later. This happened later that day when in another city and then a few more times that day. Almost had it towed but then it started. Now, after almost 1000 miles it gave up the ghost and I found one of the teeth on the relay burned and the plastic partially melted on the relay housing and the fuse panel. Went to the parts store and bought a relay replacement but it didn't do any good. Shopping for a mechanic now. My thinking is I need to get rid of it. I travel a lot throughout the snow belts in NY state and this bothers me it could happen on the highway and effect control. And a fire hazard. Why is GM not recalling this!

The contact owns a 2008 Buick Lucerne. The contact stated that the vehicle was leaking fuel from underneath the fuel tank and above the exhaust system. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

When ready to leave work the vehicle would not start. Determined the fuel pump was not operating. Replaced the fuel pump and the vehicle still would not start. I found the fuel pump relay was the ultimate cause of failure. After replacing this relay two other times I decided to look further into the cause. I dismantled the fuse box to find it was not complete inside. The fuse box is filled with female to female couplers to connect the bottom wiring harness to the fuses. The fuel pump relay should have four of the couplers installed in the fuse box. There are only three installed. The male pins are long enough to touch and make contact. They will eventually overheat. This is a manufacturing defect and a fire hazard; as many people have had the issue. Buick still has not issued a safety recall and refuses to actually investigate the reason this is happening. The average consumer is being hit wit a $400 fuse box and $600 fuel pump replacement. I actually have since installed my original fuel pump. The replacement pump did not have a sending unit for the fuel gauge. Why are the dealers replacing probably perfectly fine fuel pumps. This has become a racket.

Fuel pump shorts out and melts the fuse box this was with the car parked in the driveway could be a fire hazard if this happens you lose all control of the car and makes it a death trap

We were out of town when car failed to start, not battery related. Had to be towed to service center where they diagnosed, inspected, and replaced the fuel pump relay. On 10/01/2015, 2000 miles later similar incident except this time my local mechanic. He cleaned all cavities, applied dielectric grease, checked the fuel pump amperage at 7.5, tightened all relay contacts and replaced relay. Bad relay had scorch marks around several pins. On 10/07, 500 miles later, same scenario except this time replaced fuel pump module. On 10/10, again no start, similar, symptoms. Mechanic came to my house on 10/12, could get car to start after several tries, testing and manipulation of components, but immediately shut it down since relay was very hot. Concerned over safety, had to replace the whole module. Replacement module was definitely an upgrade to original and was such because of, I understand, the failures experienced with the originals and concern over starting a fire. I now understand that several fires resulted from this problem. Fortunately, although tremendously inconvenienced both in time and expense, no one in our family was injured nor were we the cause of any accident which on the highway could have been disastrous.

Having a problem with the car not starting. It was stationary in the garage. Had it tow to garage. They diagnosed it was a fuel relay burning up. A new relay did start the car.we took a short trip out of town and the car stopped running...left us stranded on the highway. The relay gave out again. A mechanic will now look into the fuel pump replacement. And electrical box under the seat.
