2008 Buick Lucerne Owner Comments

I bought this Buick used a couple of month ago with 87K. I've since driven over 4K miles. I bought this car because it was a big touring car and I needed something reliable and comfortable for longs days on the road. Several hundred miles ago it just wouldn't start in the driveway. Research led me to the fuse board. Checked the fuses and relays found nothing obvious. Car started up a few minutes later. This happened later that day when in another city and then a few more times that day. Almost had it towed but then it started. Now, after almost 1000 miles it gave up the ghost and I found one of the teeth on the relay burned and the plastic partially melted on the relay housing and the fuse panel. Went to the parts store and bought a relay replacement but it didn't do any good. Shopping for a mechanic now. My thinking is I need to get rid of it. I travel a lot throughout the snow belts in NY state and this bothers me it could happen on the highway and effect control. And a fire hazard. Why is GM not recalling this!

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 fuse box and $600 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.

We were out of town when car failed to start, not battery related. Had to be towed to service center where they diagnosed, inspected, and replaced the fuel pump relay. On 10/01/2015, 2000 miles later similar incident except this time my local mechanic. He cleaned all cavities, applied dielectric grease, checked the fuel pump amperage at 7.5, tightened all relay contacts and replaced relay. Bad relay had scorch marks around several pins. On 10/07, 500 miles later, same scenario except this time replaced fuel pump module. On 10/10, again no start, similar, symptoms. Mechanic came to my house on 10/12, could get car to start after several tries, testing and manipulation of components, but immediately shut it down since relay was very hot. Concerned over safety, had to replace the whole module. Replacement module was definitely an upgrade to original and was such because of, I understand, the failures experienced with the originals and concern over starting a fire. I now understand that several fires resulted from this problem. Fortunately, although tremendously inconvenienced both in time and expense, no one in our family was injured nor were we the cause of any accident which on the highway could have been disastrous.

Having a problem with the car not starting. It was stationary in the garage. Had it tow to garage. They diagnosed it was a fuel relay burning up. A new relay did start the car.we took a short trip out of town and the car stopped running...left us stranded on the highway. The relay gave out again. A mechanic will now look into the fuel pump replacement. And electrical box under the seat.

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.

Lucerne 5-cyl

  • 57,000 miles
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.

Lucerne 8-cyl

  • 86,000 miles
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.
