Review of the 2006 Buick Lucerne

  • With fewer features and weaker performance than either Toyota's Avalon or Hyundai's Azera, the 2006 Buick Lucerne is outmatched among full-size sedans. If all you want is a roomy, quiet car with a V8, it's worth a look, but most buyers will be better served by its more capable competitors.

  • Safety
  • Pros

    Extremely quiet and comfortable ride, available V8 engine, supportive front seats, huge backseat, easy-to-operate controls.

  • Cons

    Subpar brakes, sluggish handling on CX and CXL models, weak V6 for this class, lacks expected convenience, luxury and safety features, inconsistent build quality.

  • What's New for 2006

    Replacing the aging LeSabre and Park Avenue is a new full-size sedan called the Buick Lucerne. Based on the Cadillac DTS platform, the Lucerne seats up to six and can be equipped with GM's Northstar V8.

Great cruiser - but little

by on
Vehicle: 2006 Buick Lucerne CXL V8 4dr Sedan (4.6L 8cyl 4A)

I bought the Lucerne due to a job change that requires that I drive 125 interstate miles roundtrip each day. Very comfortable/roomy car that is very quiet. It was made to cruise the highway. Even with the V-8 it's not very spirited and it handles like a bus. It was not made for evasive or sporty driving. The fuel mileage has been on average about 26 mpg with 90% of driving on the highway. The cooled seats are great and keep you comfortable in hot humid weather. The Harmon Kardon stereo is average at best. It has the Continetal tires and there is a vibration the dealer can't get rid of. They claim "excessive road force variation" and it's not covered by the certified warranty.

Great car - problem fixed

Vehicle: 2006 Buick Lucerne CXL V8 4dr Sedan (4.6L 8cyl 4A)

Reading my previous review, you will see the problem with the oxygen sensor. After two more visits regarding the same problem, the GM advisor recommended that the Dealership check the wires. magic, one of the wires had a short in it which was affecting the oxygen sensor. Problem has been repaired and the car is just humming along. I would still recommend this vehicle even with my problem since that was not a design flaw but instead a supplier issue with the wiring.

Would buy another one

Vehicle: 2006 Buick Lucerne CXL V8 4dr Sedan (4.6L 8cyl 4A)

There have been two annoyances: 1. Readablility of instruments in bright sun is very poor. 2. When very hot; i.e.sitting on hot macadam for hours and/or driven hard, the steering has a tiny "thunk" feel on occasion when making a turn. It's been traced to a universal joint in the steering linkage. Dealer got 95 percent of it out, but a slight amount remains. I suspect it might be a design flaw. Had Lexus LS-400 before. Buick is as good and in many ways better. Recently drove 09 Lexus ES-350. Prefer Buick. Smooth, silky traveler; head-snapping acceleration; quieter than new Lexus; 19.7 mpg around town; very little roll on twisties (not a sporty car, though); 4-spd is slick.

Great car but...

Vehicle: 2006 Buick Lucerne CXL V8 4dr Sedan (4.6L 8cyl 4A)

I have owned this car for 10 months. Mostly highway driving. I love the ride of the vehicle and have no complaints about the gas mileage that this V8 gets (22+mph). My complaint is about the oxygen sensor. My check engine light has been a problem since 5,000 miles and it all revolves around the oxygen sensors. I have had the car in for service on 8 times and all but one was for the oxygen sensor. When I took the car in for the PA Annual Vehicle Inspection, Penske Buick had the car for over one week and finally got it to pass inspection after replacing the oxygen sensor and part of my exhaust system. Thank God for the warranty! Buick has a winner here. Just need to correct this problem.

Life saving but fishtailing

by on
Vehicle: 2006 Buick Lucerne CXL V8 4dr Sedan (4.6L 8cyl 4A)

Safety features saved my life; in avoiding a sideswipe, my car fishtailed. It wasn't easy to correct; very slow steering feedback. My last correction may have worked, had the steering been more responsive. All safety features & OnStar worked in my wreck & helped me whenever driving. I hit a light pole & metal fence at 60 mph. I'm bruised, sore, fractured collar bone; but I walked away. Compared with other cars I owned, the Lucerne wasn't as agile in handling in tight situations. Quick steering feedback is a must, or you will over correct. The '06's slight pull right ~ at least sent me into a metal fence and pole, not an embankment of trees. I had stability control and did not flip.

Low quality interior craftmanship

by on
Vehicle: 2006 Buick Lucerne CXL V8 4dr Sedan (4.6L 8cyl 4A)

This car handles very well, doesn't get good gas mileage, but it's been reliable. But I wasted too much time in the dealership for minor but annoying fixes. Right now it's at the dealer's, again, for probably the 5th or 6th time. I had gaping wholes in the posts liner, the headliner is not trimmed at the windshield, started rattling and is ragged. I've had a rattling speaker replaced. Dashboard lights are on supposedly not because there's anything wrong with the devices they warn about, but because some absconse electrical parts are defective (unclear answers from the mechanics annoy me as well). And the latest: a bulge in the tire.


Full 2006 Buick Lucerne Review

What's New for 2006

Replacing the aging LeSabre and Park Avenue is a new full-size sedan called the Buick Lucerne. Based on the Cadillac DTS platform, the Lucerne seats up to six and can be equipped with GM's Northstar V8.


So long, LeSabre and Park Avenue. Hello, Lucerne. Named after the elegant Swiss town, the Buick Lucerne is all-new for 2006. It's Buick's biggest car and can comfortably seat five adults. And though it lacks the grand name recognition of the now discontinued LeSabre and Park Avenue, the Lucerne is a welcome improvement in just about every other regard.

This newest Buick car is built at the same General Motors plant that produces the '06 Cadillac DTS, an updated version of the outgoing DeVille. The cars ride on the same length wheelbase, though the Buick Lucerne is about 4 inches shorter overall. The Lucerne's association with the DTS proves particularly beneficial in terms of powertrain. After about a decade-long drought, a V8 engine finds its way back into the Buick lineup. Available on the CXL trim and standard on the CXS, the 4.6-liter Northstar DOHC V8 cranks out 275 and 290 lb-ft of torque. As a base engine for the CX and CXL, Buick offers General Motors' tried-and-true 3.8-liter OHV V6. In this application, it's rated at 197 hp and 227 lb-ft of torque.

The Buick Lucerne also shares a couple other features with the DTS, including the Magnetic Ride Control (MRC) suspension. This is an automatically adjustable suspension damping system that's standard equipment on the CXS trim. MRC can quickly react to road conditions and driving style by altering the firmness of the shock damping. For normal driving the damping is kept soft for a comfortable ride. MRC reacts to sportier driving with firmer damping.

Buick styled the Lucerne to have a clean and attractive look. It's nothing too exciting, though the rear fascia resembles that of the 2006 Passat while front-fender portholes provide a subtle link to Buick cars of decades past (V6 models have three portholes, V8s have four). On the move, the Buick Lucerne is very quiet thanks to its "QuietTuning" initiative, which features dedicated engineering adjustments that reduce road, engine and wind noise. Ride quality is plush, while handling is unexpectedly agile for a large Buick car. The Lucerne does come up short in a few unexpected areas, however. Though standard features are plenty, common near luxury items like full one-touch windows, a split fold-down rear seat and either a telescoping steering wheel or power-adjustable pedals aren't available. Nor are HID headlights, adaptive cruise control or Bluetooth wireless capability.

Overall, the 2006 Buick Lucerne is a capable package and fares well when compared to similarly priced competitors. It doesn't match the refinement and polish of the Toyotas or the Volkswagen, nor is it a performance equal of the rear-drive Chrysler 300C, but the Buick Lucerne counters with likable driving dynamics, an exceptionally serene cabin, and a less expensive price. We recommend that shoppers looking for a large sedan in 2006 take a look at Buick's latest big car offering.

Body Styles, Trim Levels, and Options

The full-size Buick Lucerne sedan is available in three trim levels: CX, CXL and CXS. The CX comes with 16-inch alloy wheels, keyless entry, power windows and mirrors, a six-way power driver seat, a CD player and steering wheel-mounted audio controls. The CXL adds 17-inch wheels, heated outside mirrors, rain-sensing wipers, leather upholstery, a power passenger seat, dual-zone automatic climate control and an MP3-capable stereo with an auxiliary audio jack. This trim also provides access to additional optional equipment like heated and cooled seats and heated windshield washer fluid. The top-line CXS has all the CXL luxuries along with driver-seat memory, a 280-watt Harman Kardon audio system, satellite radio, 18-inch wheels and a Magnetic Ride Control suspension. Options on all Lucernes include an in-dash CD changer, a remote vehicle-start feature and rear park assist. A navigation system will be available midyear.

Powertrains and Performance

Two engines are available for the Buick Lucerne. The CX trim comes with a 3.8-liter V6 that provides 197 horsepower and 227 lb-ft of torque. Available on the CXL and standard on the CXS is a 4.6-liter V8. It's rated at 275 hp and 290 lb-ft of torque. Both engines send their power to the front wheels through a four-speed automatic transmission.


Standard safety equipment includes OnStar, antilock four-wheel disc brakes, traction control, front side-impact airbags and head-protecting side curtain airbags for all outboard passengers. Stability control and BrakeAssist are standard on the CXS, optional for V8-equipped CXL models and not available on V6-equipped models. Lucernes with the front bench seat have a two-point belt for the center position. In NHTSA crash tests, the Buick Lucerne received a five-star rating (out of a possible five) for its protection of the driver and front passenger in frontal impacts. A four-star rating was given for side-impact protection of front and rear occupants.

Interior Design and Special Features

The Lucerne's interior is cleanly styled, and the control layout is simple and organized. The leather upholstery is soft, and designers took care to match the grain patterns of the vinyls and plastics used on the dash and doors. Unfortunately, there are still a few low-grade materials thrown into the mix and build quality is inconsistent. Front seating is typically for two but a 40/20/40-split bench seat can be ordered for the CX and CXL. So done, the Lucerne can seat six. Cushioning and legroom are abundant whether you're seated in the front or back. The trunk holds up to 17 cubic feet of cargo. In addition to the folding rear seats, there is a ski pass-through.

Driving Impressions

A plush, serene ride is the top priority for the 2006 Buick Lucerne. Handling is not a strength of the softly tuned CX and CXL styles, which exhibit considerable body roll during cornering. The high-line CXS model is fairly nimble through turns, though thanks to its Magnetic Ride Control suspension. The steering feels wobbly on-center in CX and V6-equipped CXL models, so upgrading to the variable-assist Magnasteer setup available on the CXL V8 and CXS is a good idea if you can afford it. The brakes are the weakest aspect of the Lucerne's driving dynamics. Pedal feel is fine in everyday traffic, but in emergency situations, stopping distances are the longest of any full-size sedan in this price range. The base V6 engine delivers adequate acceleration but is down on horsepower for this class. The V8 provides brisk response and gets the Lucerne to 60 mph in 7.7 seconds. This is a respectable time, though V6-equipped competitors like the Avalon and Azera are quicker still.
