I have experienced an issue that seems to be of concern ( reviewed complaints filed for the same issue) for safety. My passenger side back door failed to unlock both from the inside and outside. If I were in an accident and had passengers in the back seat, this could be life threatening. I cannot image that there has not been a recall for such a serious issue. After talking to gm, they will…

What stands out
Of the 5 model years of Buick Lucerne we track for body problems, this one carries the most owner complaints on file — 46.
Owners have filed 46 body complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
The 2006 Buick Lucerne has a documented pattern of structural and mechanical defects centered on door hardware and visibility. Front door handles, made of plastic rather than metal, fracture or separate completely at relatively low mileage (54K–60K miles), rendering doors unopenable from outside. Repair costs approach $1,000.
Rear door latch failure is pervasive and dangerous. The latch mechanism binds internally when a passenger pulls the handle while the door is locked—even a single pull can cause permanent binding. Once stuck, the door will not open from inside or outside, trapping occupants in the rear seat. This occurs across the mileage range (14K–113K miles) and often affects multiple doors on the same vehicle. Temporary fixes like banging the door work briefly if at all. Dealers confirm the defect but charge $320–$410 for lock assembly replacement. GM has declined recall despite numerous complaints.
Instrument cluster design is deliberately problematic: the glare shield and chrome/wood trim create reflections that make the speedometer and gauges unreadable during daylight. Manufacturers confirmed this as intentional design, not a defect. Trunk lid support torsion bars have failed at very low mileage, and trunk lids close too easily, striking occupants. Engine motor mounts and torque bars degrade early, and plastic coolant connections leak chronically—all reportedly widespread issues GM has not addressed.

Failure modes owners describe
Front door handle fracture/separation
Driver-side or passenger-side front door handle breaks off or fractures, rendering the door inoperable from the outside. Dealers report plastic construction is the root cause; metal was not used. Repair requires handle replacement.
When: 54,589 miles; 60,100 miles reported in one case
Symptoms owners cite: Handle comes completely off while opening door; Handle fractures from vehicle body; Door cannot be opened from outside after handle failure
Repairs/costs cited: Dealership replacement of door handle assembly. One owner estimated cost at $1,000 for repair.
Recalls/TSBs owners mention: GM refused to assist under warranty (at 54K miles). Dealer stated this is a known issue: plastic handles instead of metal construction.
Rear door latch binding and failure to open
Rear passenger or driver-side door locks mechanically and will not open from either inside or outside handle, even when unlocked. Often triggered when passenger pulls handle while door is locked; the lock mechanism binds internally. Requires disassembly of door panel and manual freeing of mechanism, or door lock assembly replacement.
When: Occurs between 14,000 and 113,000 miles; one case at 28,000 miles; one at 47,000 miles; intermittent initially, becoming permanent
Symptoms owners cite: Door will not open from inside or outside handle; Door appears locked even after power unlock; Pulling handle while door is locked causes binding; Occurs sporadically at first, then becomes permanent; Passenger trapped in rear seat unable to exit; Lock/unlock cycling does not free mechanism
Repairs/costs cited: Door lock assembly replacement ($320 reported in one case; $410+ labor quoted in another). Manual workaround: bang on inside of door to free mechanism temporarily. One owner reported banging worked until problem recurred.
Recalls/TSBs owners mention: No recall issued despite widespread complaints. Dealers note defective lock mechanism. One dealer suggested using a pick inside door as temporary remedy. GM stated they would not act until NHTSA-ODI notification.
Trunk lid torsion bar failure
Trunk lid support torsion bars fail and fall into the trunk, causing the trunk lid to collapse on the occupant inside. Occurs at low mileage.
When: 14,000 miles
Symptoms owners cite: Rattling noise from trunk; Torsion bars fall into trunk; Trunk lid drops and strikes occupant
Repairs/costs cited: Dealership replaced torsion bars. Dealer confirmed bars were defective.
Recalls/TSBs owners mention: Dealership replacement provided; no recall or TSB referenced.
Roof panel separation from adhesive failure
Following a low-impact collision with a deer, the roof panel partially separated from the vehicle. Insurance adjuster and collision center determined the failure was caused by inadequate bonding adhesive and wells that did not hold properly.
When: 5,500 miles
Symptoms owners cite: Roof panel partially removed after low-impact deer strike; Inadequate adhesive bonding
Repairs/costs cited: Reported to insurance and collision center; required roof replacement/repair.
Recalls/TSBs owners mention: Owner filed complaint with Buick; no further action noted.
Instrument cluster glare and readability
Instrument panel and speedometer/gauges are impossible or very difficult to read during daylight hours due to excessive glare and lack of adequate illumination. Glare shield design and chrome/wood-trim reflections contribute to the problem. Design was confirmed by manufacturer as intentional manufacturing standard, not a defect.
When: Present from purchase/early ownership (9,997 miles; one case at purchase in January 2006)
Symptoms owners cite: Speedometer unreadable during daylight; Instrument panel gauges obscured by glare; Chrome plated dashboard components reflect sunlight; Fake wood trim reflects light badly; No daytime illumination for instrument cluster
Repairs/costs cited: No repair offered. Dealer advised this is standard manufacturing. One owner received new speedometer but still could not read it.
Recalls/TSBs owners mention: Manufacturer confirmed this is a design/manufacturing standard, not a defect. Factory noted they were aware and working on it but did not implement a fix. One dealer suggested seat adjustments as workaround (ineffective).
Trunk lid closes too easily and strikes occupant
Trunk lid closes easily on its own due to weak or faulty lid support, striking occupant in the head while working in trunk.
When: Early ownership
Symptoms owners cite: Trunk lid closes when wind blows; Lid strikes occupant in head; Lid closes too easily
Repairs/costs cited: No repair noted; owner was injured.
Side mirror roof support obstructs vision
Driver-side roof support arm attached to side mirror creates a blind spot that obstructs vision to the left, nearly causing collisions with pedestrians.
When: 9,997 miles
Symptoms owners cite: Roof support arm obstructs left-side vision; Blind spot created near side mirror; Nearly resulted in pedestrian strikes
Repairs/costs cited: Dealer-assisted seat adjustment was unsuccessful; no repair solution found.
Engine mounting and coolant system issues
Lower front motor support replacement required around 45,000 miles. Torque bar (upper front of engine) also required replacement. Chronic antifreeze leaks attributed to plastic connections; this condition is reportedly well-known online but remains unfixed.
When: 45,000 miles (lower motor support); 81,000 miles (torque bar)
Symptoms owners cite: Motor support degradation; Constant antifreeze leak; Plastic connection failures
Repairs/costs cited: Owner replaced torque bar himself (2 bolts). Motor support required replacement.
Hood latch sensor false alarm
Hood warning light illuminates indicating hood is open when hood is actually latched and closed. Warning persists while driving.
When: Unknown mileage
Symptoms owners cite: Hood open warning light activates while driving; Hood is not actually unlatched or open
Hood support operation defect
Hood support mechanism works incorrectly, opening easily but closing with difficulty. Wind can cause hood to close unexpectedly.
When: Unknown mileage
Symptoms owners cite: Hood opens easily; Hood closes with difficulty; Wind can close hood
