Owners have filed 185 complaints
about the 2009 Buick Lucerne with NHTSA between 2009 and 2026.
The largest single group is the electrical system.
Across this model's run it ranks 4 of 6 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 42
Against the median year of the Buick Lucerne. 50 means typical for this
model; 100 means roughly double.
Severity — 100
23.2% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 20
12% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2009 Buick Lucerne
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 2014246186,013 units in Canada
Electrical
On certain vehicles, a defect in the ignition switch could allow the switch to move out of the "run" position if the key ring is carrying added weight or the vehicle goes off-road or is subjected to some other jarring event. If this were to occur, engine power, power steering and power braking would be affected, increasing the risk of a crash causing injury and/or damage to property. The timing of the key movement out of the “run” position, relative to the activation of the sensing algorithm of the crash event, may also result in the airbags not deploying in a subsequent collision, increasing the risk of injury. Correction: For each key, dealers will install two key rings and modify the key ring opening shape. Note: Until the correction is performed, all items should be removed from the key ring.
Recall 201018999,000 units in Canada
Accessories
On certain vehicles equipped with a Heated Washer Fluid System (HWFS), a short circuit on the printed circuit board for the washer fluid heater may overheat the control-circuit ground wire. A repair was implemented in a recall in 2008, however, there have been new reports of thermal incidents on heated washer fluid system modules after this improvement was installed. This situation may cause some minor distortion, but also could lead to melting of the plastic around the heated washer fluid system, or cause a fire. Correction: Dealers will permanently disable and remove the heated washer fluid module. An updated page will be provided and inserted in the Owner Manual to document the removal of the feature.

The vehicle was repaired; however, the failure reoccurred 2 days later. The manufacturer was made not aware of the failure. The failure mileage was approximately 66,000.

Spartanburg, SC
ELECTRICAL SYSTEM
The car died suddenly and would not start, with no warnings or codes. Towed it to a Midas repair shop and it was diagnosed as a corroded Low Profile Fuel Pump relay. This was replaced, and the car ran fine for 3 days before going dead in the middle of driving and left me stranded in an intersection. Had to get it towed back to Midas where it was more accurately diagnosed that the issue with the relay was being caused by a faulty Rear Electrical Center. Both of these parts have been recalled, and I have only owned this car for a little over a year. It has only around 40,000 miles on it. Despite this recall, upon taking the car to the local Buick dealership, they stated they could not cover the recall due to it being expired before I even owned the car. I do not understand how it is right or fair for this to have to be paid out of pocket, for $183.53 and $818.81 respectively, when it is not my fault, it is a faulty GM parts issue, and GM stated they will not stand behind their product and cover the recall despite the evident risk to my safety if I was to continue driving the car without repair. I understand it is expired, but I fail to see how this is ethical when the part is still faulty to the point of being dangerous.

The fuse box or fuse holder under the back seat had the fuel pump relay fail due to pressure on the fuse box lid from the seat above it. This is a known issue by Buick as they keep the fuse box in stock (for about $300) I have owned two similar Lucernes with this issue. The fuel pump relay caused enough heat to melt into the fuse box, causing a disconnection. This caused the fuel pump to stop pumping, causing the car to stop running. The problem can be confirmed by calling any Buick dealer. I'm sure they have had several examples of this issue besides my pair. There are many examples mentioned on the internet, as well as videos as to how to fix it. There are no warning lamps prior to the failure. The engine dies and refuses to restart.
