Owners report multiple distinct steering failures in the 2006 Buick Lucerne. Power steering hose problems dominate complaints: leaks from inadequately crimped connectors, cracked hoses, and holes developing at various mileages. Several owners cite loss of power steering fluid, resulting in difficult steering and grinding or whining noises. A few describe hose issues going unrepaired despite dealer visits, and some note their VINs weren't included in the NHTSA recall 06V105000 despite having identical symptoms.
Chronic rightward pull afflicts multiple vehicles from early ownership (as low as 30 miles) through higher mileage. Owners report multiple dealer alignment attempts and tire replacements failing to correct the drift. Some describe needing constant steering-wheel pressure to keep the vehicle straight; others mention the problem worsens over time.
Several catastrophic failures occurred. Owners report sudden loss of both power steering and brakes while driving—one at 40 mph, another during highway lane changes—leading to crashes and injuries. One owner's steering wheel exhibited abnormal side-to-side movement before a collision; that vehicle had had its intermediate steering shaft replaced one week prior.
Additional issues include steering-wheel lockup, loose steering feel at highway speed, short looseness when turning at slow speed that recurred after dealer repair, worn plastic bushings in the steering column, steering linkage bolts detaching, and a groaning noise during turning.
Failure modes owners describe
Power steering hose connector leaks
Power steering hose connectors inadequately crimped, cracked, or with holes, causing fluid leaks. Some owners report the connectors were not properly installed at the factory.
When: 56,209 to 126,000 miles; some at low mileage
Symptoms owners cite: Winding or grinding noise from steering column; Difficult steering and hard turns; Power steering fluid visibly leaking; Steering becomes stiff or unresponsive
Repairs/costs cited: Owners report power steering hose replacement; some independent mechanics diagnosed crimped or cracked hoses; some repairs cost owners money out of pocket
Recalls/TSBs owners mention: NHTSA recall 06V105000 (steering hose, piping, and connections); however, multiple owners report their VINs were excluded despite meeting all criteria and having identical symptoms
Vehicle pulls to the right
Vehicle consistently drifts or pulls sharply to the right, particularly at highway speeds and with cruise control engaged. Problem persists despite multiple dealer alignments and tire work.
When: As early as 30 miles; continuing through 24,000+ miles
Symptoms owners cite: Vehicle drifts 3+ degrees to the right; Pulling is worse with cruise control on; Driver must maintain constant steering-wheel pressure; Uneven tire wear from constant correction
Repairs/costs cited: Multiple front-end alignments performed by dealers; tire changes and balancing attempted; XM satellite radio installation mentioned once; none corrected the issue
Recalls/TSBs owners mention: Some dealers referenced GM bulletins; no consistent manufacturer remedy documented
Sudden loss of power steering and brakes
Complete or partial loss of power steering and brake function while driving, rendering vehicle difficult or impossible to control. Occurred during normal driving and at traffic speeds, leading to multiple crashes.
When: 40 mph, 65 mph, and other highway speeds; mileages 80,000 to 100,000+
Symptoms owners cite: Steering wheel becomes very difficult to turn; Brake pedal becomes unresponsive; Loss of vehicle control; Entire instrument panel illumination in some cases
Repairs/costs cited: One case involved intermediate steering shaft replacement one week prior to failure; another involved ignition, power steering hose, air bag module, and oxygen sensor replacement
Recalls/TSBs owners mention: NHTSA campaign 14V355000 (electrical system) referenced; parts were unavailable; one owner's VIN was not included in ignition recall despite failure occurring
Tie rod premature wear and failure
Tie rods fail repeatedly within short intervals, requiring replacement twice within three years on one vehicle. Failures recur even after dealer repair and greasing.
When: First failure at 3,200 miles; recurrence at 18 months and again after 6 months
Symptoms owners cite: Vehicle vibrating and shaking when brake pedal depressed; Loose steering feel
Repairs/costs cited: Tie rods replaced on both sides twice; tightened and greased between failures; owner believes manufacturer defect
Steering column grinding noise and lockup
Grinding or loud clunking noise from steering column; in some cases accompanied by power steering malfunction and difficulty turning steering wheel. One case involved worn plastic bushings.
When: 30,000 to 72,000 miles
Symptoms owners cite: Grinding or clunking noise from steering column; Steering wheel becomes very difficult to turn; Power steering malfunctions or fails to respond
Repairs/costs cited: One owner told dealer cost would be $300+; worn plastic bushings identified as cause in one case; one vehicle had steering column issue but no recall available
Recalls/TSBs owners mention: One case: dealer stated repair was out of warranty and refused; another noted no recall available
Steering linkage bolt detachment
Steering linkage bolts detached, causing steering failure. Bolts used were not factory parts, resulting in improper fastening.
When: <UNKNOWN>
Symptoms owners cite: Steering failure
Repairs/costs cited: Non-factory nuts were used with steering linkage
Loose steering at highway speeds and slow-speed catching
Steering feels light and wanders at highway speeds; at low speeds, steering feels like something is catching or binding. Some describe short looseness when turning that recurred after dealer repair.
When: 65+ mph highway speeds; low-speed parking and driveway maneuvers
Symptoms owners cite: Steering wanders or feels light without constant attention; Thumping or catching sensation during low-speed turns; Steering feels inadequate or lacking positive caster
Repairs/costs cited: Dealer corrected similar issue under warranty but problem recurred approximately 18 months later
Rack and pinion premature failure
Rack and pinion gear requires replacement and fails again at relatively low mileage, making same noise shortly after repair.
When: Failure recurred by 120,000 miles after replacement
Symptoms owners cite: Noise from steering
Repairs/costs cited: Rack and pinion replaced; same issue recurred shortly after at 120,000 miles
Recalls/TSBs owners mention: Owner questions why no recall exists
