    Fuel pump stopped pumpimg without warning. Had car towed to my garage wgere they advised me fuel pump was defective. after replacing fuel ump it was discovered the fuse box under the rear seat was fried. Car was then toewd to the local dealer where fuse bx was replaced and reprograming was necessary. i checked for a recall and was told there was none.

    FUELPUMP RELAY BURNS OUT, X 3, DEALER REPLACED FUSE BOX, CLEANED BATT. TERMINALS, TRACED WIRES, REPLACED PUMP, AND NOW SAYS IT IS THE FUEL GUAGE SENDER THAT IS BLOWING RELAY. GUESS WHAT; THEY WANT TO MAKE ME PAY FOR ALL THIS WORK. HAD TO HAVE CAR TOWED TWICE, DEALER WOULD NOT GIVE ME A SPARE RELAY SO I WOULD NOT HAVE TO HAVE IT TOWED. I WAS THE ONE WHO BROUGHT THE HOT RELAY PROBLEM TO THEIR ATTENTION. THIS IS A TIME BOOM WAITING TO HAPPEN. BURNING RELAY NEXT TO BATTERY UNDER BACK SEAT.

    Stop and tried to start the car and it would not. It was traced to a bad fuel pump- car has abt 66,000 miles

    same issue. would crank but not start. The fuel pump and relay were replaced and not even a month later, the relay melted from who knows what. i talked to the mechanic that fixed it again and he stated that the fusebox or module has problems with it that may be an engineering flaw.

    2 weeks ago, went to start vehicle and it was not getting gas. Had it towed and diagnosed as fuel pump. Had pump and relay replaced (relay was melted). 2 weeks later, I went to start the vehicle, same problem. Had car towed again and once again the relay is fried. Mechanic opened up fuse box and seems to be an electrical problem where too much power is going to the relay causing overheating and pump failure.

    55 miles from home at my daughters house. I tried to start my car and all it would do is turn over. I checked to see if it was getting gas and it wasn't. started to look for the fuel pump fuse. found it under the back seat. right next to the fuse(20 Amp)was a toasted fuel pump relay. When I removed it I found the fuse block had fried because of the relay. Apparently it had melted some internal wires on the block because when I put a meter on it there was no current going from the relay to the fuse. I jumped the relay and the fuel pump was fine. I am having a hard time finding a replacement for the block. From what I've read they run around $350. This definitely seems like an engineering design problem. the more I look the more cases I find. I plan on measuring the amps that are running through that circuit. I can't believe this wasn't a recall. Although given whats been happening in the new with GM recently, maybe I can. I like the car not its manufacturer so much.

    in December 2013 parked my car that night, and early that morning it wouldnt turn over. Replaced the fuel pump still no change. Towed to dealership and was told there was a short in a wire harness under the hood of the car. Not even 3 months later went out to start and same thing happened, so towed to same dealership thinking they didnt repair it correctly and this time was told that the fuse box under the back seat was shorted out and fried the relay switch and the entire box needed to be replaced..a total of $680 in all. No open recalls for this problem online at all. Discusted because i love my Buick but i cant continue to put up with this problem. It happens with no fore warning at all!!!

    Car would not crank without warning. Was towed to dealership and fuel pump replaced. Car has been serviced at dealership since purchased new an d no mention of need for fuel filter replacement. Hope it doesn't do it again like other reports. I will try to remember to have fuel filter replaced in future.
