Review of the 2005 Buick LaCrosse

  • With more refined power under the hood and a contemporary interior, this replacement for the Regal and Century could go a long way toward reestablishing Buick as a premium brand.

  • Safety
  • Pros

    Six-passenger seating availability, supremely quiet ride, powerful and refined engine in CXS model, attractive interior.

  • Cons

    Stability control limited to CXS trim, base engine lacks refinement, only comes with a four-speed automatic.

  • What's New for 2005

    The LaCrosse is an all-new premium sedan replacement for both the Century and Regal sedans.

Vehicle: 2005 Buick LaCrosse CXS 4dr Sedan (3.6L 6cyl 4A)

Pile of junk, trouble with telescoping steering, ongoing problem. Wheel bearings replaced at 75000 kms. Two sets of brakes, car has 105000 kms. Air bag light goes off and on, never fixed. Fog lights did not work got them fixed then horn went out at 62000 kms. not covered by warranty, cost to fix $1100.oo. Front doors leak water when it rains. Tires replaced at 30,000 kms. Noise coming from front end when driving never were able to fix. Engine icon light comes on due to them screwing with the bundle of wires when they fixed the lights and horn, cost to replace the wire bundle would be over $2000.oo. The list is almost endless.

Vehicle: 2005 Buick LaCrosse CX 4dr Sedan (3.8L 6cyl 4A)

At 27K miles it whined when steering.GM offered no help.At 49K miles it was getting worse.Went to Bellavia in East Rutherford, NJ.Told me power steering pump is leaking, rack and pinion assembly is cracked and something is wrong with the sway bar and end link. Also need an alignment and new front brakes. Bellavia Cost 1,992.00. GM offered no help. Went to my trusty car care center and only needed the rack and pinion assembly replaced since it was leaking and an alignment. The steering pump and brakes are good. My Trusty Car Care Center Cost 554.01. Also, since new; water leaks through antenna and squeeks in the rear on bumps. Why so many problems?

Not good long term

Vehicle: 2005 Buick LaCrosse CXL 4dr Sedan (3.8L 6cyl 4A)

I have driven GM cars for the past 32 years and have obviously been very pleased or I would have changed. I like the size, performance, styling and comfort of my La Crosse. I purchased it in 2005 with less than 15,000 miles on it and have had very few problems UNTIL it reached 90,000 miles. After that everything seemed to go wrong with this car almost at once. It's been properly maintained the same as all previous vehicles which lasted 150,000 + miles without problems. I am very disappointed in this vehicle for that reason alone.
