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.

The contact owns a 2008 Buick Lucerne. The contact started the ignition and a few moments later the engine stalled. The contact was a certified mechanic, who replaced the burned fuel pump relay switch. The failure recurred twice and the vehicle was repaired each time. The manufacturer was not notified of the defect. The approximate failure mileage was 60,000.

When my wife was parking the car in a shopping center parking lot, the engine roared (even though she had her foot on the brake) and the vehicle jumped over the curb and struck small bushes and trees in the median between the stein mart and home dept parking lots causing damage to the front grill and driver side front fender. My wife was not injured luckily. Had this event occurred under normal driving conditions somebody could have been seriously injured and or killed depending upon the circumstances. I had a similiar instance about a year ago when the car surged forward while I was stopped at a intersection. My foot was on the brake and I got the car stopped. I continued to drive the car and did not experience any further problems. I thought it might have been a stuck accelerator linkage that cleared. I've since learned the newer vehicles are drive by wire controlled. Their is no direct throttle linkage from the gas pedal. The vehicle is currently at a Buick dealers body shop being repaired.. their service manager stated they would read the computer codes and use a scan tool to determine what caused the accident. An accident report was recorded by the local police department.

Fuel gauge is inaccurate. Reads up to 1/4 to 1/2 tank too full or too empty. Took it to GM repair facility (dealer) 5 times where numerous and different repairs were done over the course of about 7 months, but still not fixed. Have to keep filling the tank since fuel level is unknown. Collision hazard if run out of fuel while driving.

Purchased vehicle 4/2/12. 6/30/12 car would not start. Full power and crank but would not engage. Car towed and diagnosed as fuel pump/relay. The relay was melted. Repaired without incident. July 23,2012 car repeated. No start. Car towed again and relay is melted again. Researching it seems to be a common event occurring in 2008 V8. Mechanic has determined it to be an electrical problem stemming from fuse and amps being delivered to relay. The consumer stated the manufacturer exceeded and a reasonable amount of time addressing the failure.
