What owners wrote
-The electrical system failed, causing the fuel pump to not work properly due to design flaw in the backseat putting pressure on the fuse box which is located under the backseat. The spot where contact is made to the fuse box, is where the fuel pump relay is. Pressure from the seat bracket (with or without a passenger in the seat) causes the pump replay to not make proper contact with the terminal, therefore causing the power to arc and get so hot that the relay starts smoking, melting the relay, fuse box and…
Tl* the contact owns a 2008 buick lucerne. The contact stated while traveling 55 MPH, there was a burning smell throughout the vehicle. A private mechanic replaced the starter relay switch; however when the contact started the vehicle the following day the fuse box was burned out. The vehicle was not repaired. The manufacturer was notified and stated that the fuse box needed to be replaced. The failure mileage was 42,000 and the current mileage 44,000.
