  • 85,000 miles
The contact owns a 2009 Buick Lucerne. The contact stated that the vehicle failed to start after being filled with fuel and the instrument cluster failed to illuminate. The failure recurred multiple times. The vehicle was taken to an independent mechanic for diagnostic testing where it was diagnosed that there was a short in the fuse block. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 85,000.

Vehicle was stationary in driveway. Vehicle would not start. It had worked fine the day prior. The vehicle was cranking and clearly had power but would not turn over. I noticed that I could not hear the fuel pump prime when the key was turned. Like many others, I found the fuel pump relay to be charred like it had been burning. The fuse block was also melted at pin 30. This is such a fire hazard being under the back seat, dealing with the fuel pump, and overheating like it does. It seems to be a commonly reported problem and I cannot believe there has not been a recall. Currently waiting on parts to replace the melted fuse block and the relay.

Driving down the road the car quits and cranks but no start. Found fuse box at fuel pump relay melted together. Cleaned terminals and replaced relay drove car 20 miles to have it do it again. Fuse box get hot and it is located under rear passenger seat next to battery. I have read where other people with same year, make and model having the same problem and around the 70,000-80,000 mileage. I feel that it is a safety problem in both accidents and fire.

Vehicle would not start in the garage. Had it towed to a local garage where the diagnosis was failed fuel pump relay. Fuel pump relay overheated and melted the fuse block. The 20 amp fuse for the fuel pump relay did not fail. A visual inspection of the relay shows an internal burn mark between pins 85 & 86. Since this block is under the rear seat, on which my grandchildren our strapped in I am concerned about the chances of fire. As far as I can tell their is no recall, but a quick search of the internet indicates an ongoing problem.

My 2009 Buick Lucerne that I use in my daily commute to work did not give me any issues until that Friday,10/23/2015. I tried to start my vehicle that morning and it seem as if it was not getting any fuel. Had the vehicle tolled after contacting my extended warranty company. Monday I received a call from the dealership that the problem was diagnosis as the fuel pump relay has not only overheated but has melted the fuse box. My concerns are that this could have occurred while I was driving, also this seems to be a known but not publicized issue by both the manufacturer and the insurance company. Too many identical incidents have occurred and has been reported, yet no one has received any reported action to correct this dangerous problem. It does not take a mechanical expert to know that a device that can cause fire to something associated with the fuel system is a matter of great concern. Hopefully this problem will be taken seriously before something fatal happens.

I was driving down the highway when my car just stopped running. Luck had it I wasn't on an interstate, thirty minutes later I would have been. (I'm a retired mechanic of 48 years.) up on checking the car I found that there was no fuel pressure. Had the car towed to GM auto center in laramie, wy. I told the service writer that I presumed that the fuel pump had went out. When the tec. Ran diagnostics and a visual check they found that the fuel pump control module and fuse box were burnt. The tec. Told me that he had seen this before and showed me another fuse box with the exact damage. After returning home I was told by another mechanic that one of his customers had the same problem. This is a serious problem as all these items get melting hot and are located under the back seat just in front of the gas tank which is plastic and the seat is nothing but foam creating a serious fire hazard. I had the recall on the ignition switch done. After my experience with my car I think it was a smoke screen for the real problem the fuse box, fuel pump control module or fuel pump. No one wants to take this seriously. This all started on 09/25/2015 car millage 61855. I have the items in question.

Car cranked but would not start. Diognostic indicated fuel pump was unable to get pressure. Recommended by technician to replace fuel module. Car started following installation of fuel module. Following a complimentary wash car would not start. Technician determined that fuel pump relay and block had been burned. Because I was concerned that I had paid for parts and labor that were not necessary, I did research on line and found that the fuel pump relay burn out had been a problems since 2006. Online I noted that many complaints have been made concerning this fuel pump relay. According to several people who have had this problem, it is very dangerous as the fuel pump relay and block actually creates enough heat to cause gas tank and battery to ignite. Since this apparently has been a problem since Lucerne 2006, why has this problem not been addressed as it is life threatening?

6/2/15 vehicle would not start, full power and crank but would not engage. Car towed to Buick dealer where I purchased car. Ck ECM codes - none ck ign and fuel system - no fuel pressure - ck fuel deliver system found fuel pump failure. Replaced fuel module assembly. $624. 6/08/15 vehicle wouldn't start. Pulled relay for fuel pump and put it back in and it started. I drove it back to the dealership. They checked fuel pump relay, found rear fuse panel damaged due to poor connection at fuel pump relay. Replaced rear fuse block. Cost $291. After doing some research problem seems common and stems from an obvious problem with these fuse boxes. Read there was a national backorder on these fuse boxes at one point. Sounds like this should of been a recall and replaced for free.

The contact owns a 2009 Buick Lucerne. The contact stated that the vehicle randomly lost power. Once the vehicle restarted, it would shutter and jerk. In addition, the speed would accelerate and decelerate during the failure before returning back to normal. The engine service center light would illuminate on the instrument panel and the traction control and anti-lock brakes would not work. The vehicle was taken to the dealer where it was diagnosed that there could be a bad connection between the accelerator pedal and the fuel being sent to the engine. The vehicle was not repaired. The failure mileage was 68,000.

Lucerne 6-cyl

While driving in petoskey the car started to miss an backfiring then the motor stop running. I couldn't stop or steer the car. After I got the car finely stopped the car wouldn't start up an I could smell like wire burning. I had the car delivered to an auto shop brown motors in harbor springs mi. After the diagnosis they found that the fuse block under the rear seat was burned up at the fuel pump fuse, an was on fire at one time.. the fuse block was beyond fixing an needed a new one installed. There was a recall on the ignition switch, but this isn't what is wrong with these cars, I don' believe that the ignition switch on there recall are what is wrong, I believe that the fuse block is what wrong with there recalls when the fuse shorts out the fuel pump stops an so does the car motor. Strange that the car dealers for some reason has them in stock, there should be a recall on all car with this type of fuse box, this is what causing these car to stop running an get in a accidents. To day I got lucky.
