2006 Buick Rainier review: Our expert's take

Vehicle Overview
As the 2004 model year began, a midsize luxury sport utility vehicle dubbed Rainier joined the Rendezvous “crossover” model in Buick’s lineup. Built with full-frame construction, the Rainier can carry up to five occupants.

Rainiers come with rear- or all-wheel drive. All are built on General Motors’ short-wheelbase midsize SUV architecture, which is also used for the Chevrolet TrailBlazer and GMC Envoy. An electronically controlled rear air suspension is intended to produce a comfortable ride.

An inline-six-cylinder engine is standard, and it gains 16 horsepower for 2006. A 5.3-liter V-8 is optional. Woodgrain trim is standard on the instrument panel, doors and center console. Side curtain-type airbags are available.

Though it is intended primarily for driving on regular pavement, the all-wheel-drive Rainier offers offroad capability, according to Buick, and is said to be “very capable on . . . an unpaved, two-track road.”

For 2006, a new front grille and tri-shield emblem are installed. Sculpted wheel flares and shoulders are meant to enhance the Rainier’s appearance.

Clear headlights have offset high/low beam fixtures. Fog lamps with chrome surrounds are standard. Two-tone front and rear fascias are body-colored over gray, with the gray portion extending into the rocker panels. The Rainier features 17-inch wheels, power rack-and-pinion steering and Bilstein shock absorbers.

Perforated leather upholstery is standard, and heated front seats are optional. The monochromatic interior features chrome accents and dark woodgrain trim. Standard steering-wheel controls operate the stereo. With the 60/40-split rear seats folded, the Rainier has 80.1 cubic feet of storage space.

The instrument panel features green-needle gauges that are reminiscent of those in the Rendezvous. Dual-zone automatic climate control is standard, and the Rainier is equipped with GM’s OnStar communication system. A navigation system, DVD video system and XM Satellite Radio are optional.

Under the Hood
A 291-hp, 4.2-liter inline-six-cylinder is standard, and a 300-hp, 5.3-liter V-8 is optional. A four-speed automatic is the sole transmission.

Optional side curtain-type airbags incorporate a new rollover sensing system for 2006. All seating positions have three-point safety belts, and all-disc antilock brakes are standard. GM’s StabiliTrak electronic stability system is also standard.

Very comfortable and powerful BUICK

This car meets my expectations to comfort, interior design and the power it has. The ride is smooth and size has been right for what I need a car for. I would buy this model again.


I love my Buick

I have had this car for 8 years. I love it. It is so comfortable. I could get 8n it load my family up and go anywhere. The comfort is amazing.


Best vehicle I've owned

I bought my Rainier when it had 6,800 miles. I only recently sold it with 236,000 miles on it. I tried to find a low-mileage Rainier as a replacement, but apparently everyone who owns one keeps it until it has high mileage. The Rainier was very reliable for me. The only major thing I ever had done was replace the air suspension components. It cost around $1k to do, but was well worth it to keep the excellent ride it always had. It was truly a great vehicle to own and drive, and I'm surprised more people didn't buy one.
