Problems with 2008 Buick Lucerne ELECTRICAL SYSTEM

Car has gone through 3 fuel pump relay fuses in 3 months last one started on fire just from starting vehicle

Tl* the contact owns a 2008 buick lucerne. when attempting to start the vehicle, it would crank, but there was no fuel being transferred to the engine. the vehicle was towed to a certified mechanic who diagnosed that the fuel pump and the fuel relay both failed and needed to be replaced. the vehicle was towed to borcherding buick gmc (located at 9737 kings auto mall rd, cincinnati, oh 45249, 866-666-6291) where it was further diagnosed that the failure was due to an overheating of the electrical fuse box that burned the relay. the vehicle was repaired. approximately three days later, the failure reccured. the manufacturer was made aware of the failure and stated that due to the vehicle no longer being covered under the special coverage, they were unable to provide a repair. the approximate failure mileage was 55,000.

Fuse box under the seat overheats and burns out fuel pump relay along with the fuse box. unsafe if it happens while driving

Twice in the last twelve months there has been a short in the tail light assembly resulting in my battery getting drained. i could not get to my tools in the trunk because i could not get the electrical system to open the trunk and i could not open it manually. the short has been due to an electrical wire being pinched between a washer and the frame when the tail light assembly was replaced after a bulb was replaced. it caused my car to die while running.

Fule pump relay fuse box cought fire

My car shut off will not start with key in the ignition, and when started with the keyless remote it still will not move and car will not come out of park. the whole entire ignition system is locked up. i tried my spare key the car has shut down and it had to be towed home. the car was stationary.

Tl* the contact owns a 2008 buick lucerne. the contact stated that the fuse box failed three times in three months. also, while driving, a burning odor was detected. there were no warning indicators illuminated. the contact coasted the vehicle over to the side of the road, opened the back seat of the vehicle, and noticed that the fuel fuse was burned. the contact replaced the fuse, but the failure recurred. the vehicle was towed to an independent mechanic where the fuel box and fuel pump were replaced; however, the failure recurred. the contact spoke with murdock hyundai logan (located at 3131 main st, logan, ut 84341, (888) 494-8023) and the contact was informed that there would be a fee for diagnostic testing and repairs. the vehicle was not taken to a dealer and was not repaired. the manufacturer was not notified of the failure. the approximate failure mileage was 110,000.

Experienced a crank no start on my 2008 buick lucerne, did some research to find this make/model/year has a long history of issues with the rear electrical center due to the placement under the back seat. the fuel pump relay fuse was extremely burnt and noticed the fuse box was melted near the relay fuse. brought my car to the local buick dealership and they notified me a 10 year "special coverage" was available on this car but i was never notified of the issue. i am the 2nd owner of this vehicle. ended up having to pay for an entire new rear electrical center and the labor to replace it (~$700). i called gm customer service and they said they wouldn't be able to do anything about it. if the electrical box is being burned and it's directly under a seat i fear this is a major safety concern. i believe this should have warranted a recall and it absolutely should be required for gm to notify the current owner of the vehicle for this issue.

Car wouldn't start checked fuse panel and fuel pump relay terminal is melted upon further research this is a common occurrence in the 2008-2011 buick lucerne models caused by the panel being directly under the rear seat bracket. bracket applies pressure to panel lid which intern pushes and applies pressure to fuel pump relay gm recommends replacing relay with low profile style relay and cutting seat brackets. if this is such a know issue and gm recommends these modifications why is this not a safety recall? if the terminal is melting and burning like that this could cause a fire directly under a foam seat in the rear of a car and in my case directly under my children's car seats!!!!!!!!! i have to replace the entire fuse panel due to the melted contacts with estimate repair costs of over $300 for something that could be prevented by gm doing the right thing and fixing their problem!

I receive a letter from gm stating that the rear seat brackets may contact the electrical system causing damage including fires and draining of the batter. the letter further gave a very narrow time frame as well as conditions where owners could get reimbursement or repair of the problem which prohibits myself other owners from being able to correct this design defect without incurring sizable repair bills. i have replaced my battery twice because of the draining issues. the vehicle can not stay dormant for more than 2 days before the battery dies. it is unconscionable as well as an unscrupulous business practice to not recall the affected vehicles and have the problem corrected at no costs to the owners. i am lucky that it is just a battery drain, in some cases there have been fires and engine stalls. this is a potential life-threatening problem that should be corrected by gm immediately.

I received a letter in january, 2019 regarding this vehicle, stating that the "vehicle's rear seat bracket could contact the vehicle's rear electrical center (rec), which can, over time, damage electrical components within the rec enclosure. if damage occurs, the components can melt or overheat, which the customer may detect by a melting odor in the vehicle. damage could also cause the vehicle's battery to drain, a no-start condition, or a stall." we have had 2 new batteries installed in this vehicle in recent years and i've also smelled the burning smell that they are referring to in this letter. i took the vehicle to shelton pontiac buick in rochester, mi to find out if our car had been affected by this condition, and after examining the rec harness, they said that it has been affected and needs repair. they quoted me $720 to repair it. buick was the one who contacted me regarding this situation, which is unsafe and should be under a recall with no charge to the customer to fix. it is a manufacturer's problem and not due to wear and tear and i believe i should not be charged for this repair ...

My battery is located under the back seat and caught flames yesterday with my small children in the back. i dont understand why u would put a battery under a passenger seat where people sit on top of with fabric

Takata recallrelay to fuel pump in fuse box under drivers side rear seat. keeps melting (relay and fuse box) leaving an electrical fire smell in car. this is the 2nd box and fuel pump to be replaceed in less than 2 years.

Tl* the contact owned a 2008 buick lucerne. after starting the vehicle, an electrical surge occurred and the driver noticed smoke under the hood. after opening the hood, flames appeared from the engine compartment. the fire department was called to the scene and extinguished the flames. the vehicle was destroyed and towed away. the cause of the failure was not determined. the manufacturer was not notified of the failure. the local dealer was not notified. the failure mileage was 170,000.

Automatic door locks on various doors have failed repeatedly. this problem has required entire replacement of the door lock/latch assembly's which is quite expensive. failure of door locks is sometimes not immediately noticeable since it is intermittent at first, until it does not work at all. children or persons could fall out of car as result of failed locks that you think are locked but they are not. you rely on the door locks to keep everyone safe from accidentally opening the doors.
