What stands out
Of the 4 model years of Buick Lucerne we track for brakes problems, this one carries the most owner complaints on file — 12.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This Preliminary Information communication provides information to the technician about changing the tire and wheel size on vehicles. General Motors will only support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications. Technician should not use the information that is provided by the antilock braking system tire size selection.

Technician may find Diagnostic Trouble Code P0442. Technician will need to review Techlink article from May 2013 titled "Using the Evaporative Emissions System Tester" Technician will need to follow these steps to help diagnose the issue. First after the P0442 has been verified do not disturb any of the fuel system components. The technician now can use the scan tool to close the Evaporative Emissions System. If possible change the tank pressure sensor units from inch_H2O to milimeter_Hg for better resolution. Now the vehicle can be star

The failure pattern owners describe
Owners consistently report severe front-end vibration and shuddering when applying brakes downhill, with steering becoming hard to control at speeds above 40 mph. Multiple owners describe the problem worsening over time despite repeated dealer repairs. Dealers have replaced rotors, attempted turning, and replaced calipers, but the vibration persists. One dealer initially acknowledged a design defect in lightweight rotors and calipers but later refused repairs after the owner sought independent service. An independent mechanic recommended upgrading to heavy-duty components for about $2,000, which reportedly fixed a similar Cadillac issue.
Separate brake failures include an ABS unit that engaged during parking on dry pavement, preventing the vehicle from stopping and resulting in a crash. Another owner's brake pedal sank to the floor during braking, pushing the foot onto the accelerator and causing unintended acceleration through a stop light. A rear brake line was discovered incompletely installed and routed to the sway bar, creating leak risk. One owner reported rust-related brake lining failure at 18,000 miles. Brake system warning lights gave false signals after dealer service, and multiple owners note Buick support was unresponsive or unwilling to address the problems.
Failure modes owners describe
Brake rotor warping and vibration under braking downhill
Rotors warp during downhill braking, causing severe vibration and shimmy in the front end and steering wheel. Multiple owners report the problem worsens over time. Owners describe extending stopping distances and difficulty controlling the vehicle at speeds above 40 mph. Dealer repairs involving rotor turning and replacement have failed to permanently resolve the issue.
When: 7,500 miles and beyond; most common downhill or in mountainous terrain
Symptoms owners cite: Severe front-end vibration and shimmy when braking downhill; Steering wheel vibrates and becomes hard to handle; Shuddering or shaking during brake application; Reduced stopping power relative to brake pressure applied; Extended stopping distance; Loss of vehicle control reported during braking; Problem worsens progressively with use
Repairs/costs cited: Dealer replaced rotors and attempted rotor turning multiple times (one owner notes rotors can only be turned twice). One independent mechanic recommended upgrade to heavy-duty rotors and calipers for approximately $2,000; dealer refused after customer used independent shop. Dealership cited lightweight rotors, calipers, and brake pads as design defect but declined warranty coverage.
Recalls/TSBs owners mention: Buick initially stated they would not repair due to high repair expenses. Dealership claimed design defect in lightweight components but refused coverage citing driver braking habits and gender bias.
ABS malfunction and loss of braking control
Anti-lock brake system engaged unexpectedly during parking on dry asphalt surface, causing extended stopping distance. When owner pressed harder on brake pedal, vehicle did not stop and ABS continued pumping. Resulted in crash into tree.
When: Specific mileage unknown; occurred during parking maneuver
Symptoms owners cite: ABS engaged on dry asphalt without cause; Extended stopping distance despite increased brake pedal pressure; ABS continued pumping after engagement; Vehicle would not stop as expected
Brake pedal sinking and loss of braking capability
Brake pedal slowly sinks to the floor during braking, forcing driver's foot onto accelerator pedal simultaneously. At stop lights, this causes unintended acceleration through the intersection via anti-lock brake engagement.
Symptoms owners cite: Brake pedal gradually sinks to floor under braking; Foot pushed onto accelerator pedal at same time; Anti-lock brakes engage at stop lights; Unintended vehicle acceleration through intersections
Brake-line installation and routing defect
Rear brake line discovered not fully installed from engine to brakes and routed/tied to sway bar. Installation defect creates risk of brake fluid leak.
When: 56,620 miles
Symptoms owners cite: Incomplete brake-line installation; Brake line routed to and tied to sway bar; Risk of brake fluid leak
Repairs/costs cited: Independent mechanic replaced brake line; defect discovered during subsequent dealer inspection at Suburban Buick GMC of Ferndale, Michigan.
Front brake caliper defect causing vibration
Right front brake caliper found defective, causing front-end vibration during braking. Vibration persisted even after dealer replacement of caliper.
When: Early ownership (defect present on delivery of new vehicle)
Symptoms owners cite: Persistent front-end vibration during braking; Vibration continued even after rotor replacement and wheel alignment
Repairs/costs cited: Dealer identified defective right front brake caliper and replaced it. Vibration issue persisted after repair.
Brake system corrosion and premature wear
Brake lining and related components corroded due to rust at 18,000 miles, requiring replacement.
When: 18,000 miles
Symptoms owners cite: Rust on brake components; Brake lining degradation
Repairs/costs cited: Garage recommended replacement of brake lining and gas line due to rust.
Brake system warning lights and false warnings
Traction control indicator and service brake assistance warning illuminated when vehicle was not moving, indicating false or erroneous warnings from brake system electronics.
When: 12,000 miles (warning lights appeared after dealer installed data processor)
Symptoms owners cite: Traction control indicator illuminated when vehicle stationary; Service brake assistance warning when vehicle stationary; False warnings appearing after dealer service
Repairs/costs cited: Dealer installed data processor and instructed owner to push button when problems occurred. This led to false warning generation.

What does it cost to fix?
Independent shops typically charge around $450 for brakes repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
