Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

problem #48

  • 92,000 miles


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.
