Fuel pump repaced 2015, 54000 mileage, then fuse box melted 1-04-2017 74000 mileage and was stranded. Found out these two problems tied together from other compaints.no recalls or any reimbursement. With this many complaint issues I feel something should come our way for owning a biuck which I grew up being told you can't go wrong with a Buick... not right. $ 1300 later still waiting!

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!

Our 2008 Buick Lucerne was in the hov lane traveling on 84 w toward hartford, ct. Without warning - no warning lights came on - the car started to decelerate. My daughter tried to accelerate and nothing happened; she then tried to brake to pull over and was unable to freely turn the wheel. She struggled to move to safety to the shoulder on the side of the road but then felt the steering wheel and brakes lock completely as the car stalled. When she attempted to restart the car to move to safety, the car violently shook. Since the car was still partially on the highway, my husband and I called the ct state police to request help while my daughters were waiting for aaa. When the trooper arrived on the scene he called us to say that the car was partially in the road and that two cruisers were there to ensure the safety of our daughters. The car was towed to our service station of 25 years in scranton pa and found that the fuel pump relay post had overheated and melted. A diagnostic test did not reveal any problems either. The car had to be towed one week earlier to this same station because the car was shaking violently. After a diagnostic test revealed nothing, they determined that the car was low on fuel (and that it wasn't a fuel pump issue). We then drove the car another 517 miles without incident. I have found that complaints have been filed with Buick (I have filed one too) regarding this problem and that fires have resulted from the overheating. These complaints indicate that sometimes the car starts, sometimes it doesn't. I believe these 2 incidents, one week apart, were related and that both times, no warning or diagnostic test revealed a problem. If my daughter had been driving on the 4 lane highway leading into hartford and this problem occurred, I have no doubt that she and my other daughter would have been in a serious, if not fatal accident.

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.

Electric components of fuel delivery system short causing fire hazard. The fuel pump, fuel pump relay, and under seat fuse panel malfunction causing the relay and fuse panel to overheat and melt down. The heat builds while driving or while starting. This happened three times in a week.

On July 26, 2016, while driving on cleveland drive, lots of smoke started coming out from under the hood of the car then all of a sudden fire started to shoot out as well. There were no issues previously with the car as it was in perfect condition inside and out. I contacted Buick to see if the car was ever recalled but it was not, however, it probably should have been. Now I am without a car because it was deemed a total loss. I attached pictures but did need to upload the fire dept report.

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.

The fuel pump relay overheated and melted in the fuse box. I had to have the relay and fuse box replaced. The mechanic told me that the fuse box could have started a fire. He told me to google the problem with my car because hundreds of other car owners have had the same problem. Sure enough I did just that and I saw hundreds of people with the same complaint about this model car. GM needs to be held accountable. Are they waiting until somebody dies first before they acknowledge the problem of the fuel pump relay and the fuse box? btw I had to replace the fuel pump.

Lucerne 6-cyl

  • 52,000 miles
Driving down highway and vehicle stalled for no reason. Engine light did not come on. Attempted to start, but nothing happened...no click, no crank, nothing. Had to wait 10 min. Until key start attempt did anything and then ran fine. Have been driving in town ~35mph as well as slower speeds and vehicle will do the same thing...stall. Attempted to start, but nothing happened...no click, no crank, nothing. Had to wait 10 min. Until key start attempt did anything and then ran fine. This has happened approximately 12 times in the last 2 months. The GM recall (solution was a key insert) has been performed and this issue has occurred before and after the recall fix.
