car   Car Will Not Start problem 1
Failure Date: 06/27/2015

The contact owns a 2008 Buick Lucerne. After the vehicle was driven for approximately 100 miles, the contact parked the vehicle. When the ignition was turned to the on position, the engine did not start. The contact noticed a burning odor coming from the rear of the vehicle. The contact replaced the relays and the engine restarted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 57,000. The VIN was unavailable.

Failure Date: 06/10/2014

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. 00 fuse box and $600. 00 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.

Failure Date: 11/23/2013

Car would not start, and the fuel relay fuse had blown, damaging the fuse box. Fuse was replaced and on Dec 4, 2013 the car would not start again. New fuse block had to be installed. Mechanic's diagnoses said the fuel pump was not receiving good voltage at time, further inspection and testing showed under the rear seal left side fuse block is receiving good voltage but sending a low voltage signal to the fuel pump. Further investigation shows a burnt and melted high resistance connection at the fuel pump relay. Normally, I understand the fuse next to the relay should have blown. Problem seems to stem with the fuse box and there was only one available in the united states on 12/4/2013 which I got. My mechanic was told they are on national backorder and it could take up to 6 months to receive one. So there is an obvious problem with these fuse boxes.

car   Car Will Not Start problem 4
Failure Date: 06/30/2012

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.
