Model Overview:

At its debut, the Buick Rainier added a bit of diversity to the brand's rather uniform lineup. Joining a family of mostly big, softly sprung sedans, this truck-based, midsize SUV became the first Buick in a long time with traditional body-on-frame construction and rear-wheel drive (with optional all-wheel drive), enabling it to carry a considerable amount of cargo (80 cubic feet) and tow heavy loads (up to 6,700 pounds).

Buick sourced the majority of Rainier's design from General Motors' midsize SUV platform. This meant that there wasn't much variation between it and its GM sport-ute brethren like the Chevrolet TrailBlazer, GMC Envoy and Oldsmobile Bravada -- the third of which the Rainier effectively replaced when the Olds division was discontinued.

Of this core SUV grouping, the Buick Rainier was meant to be the most comfortable and upscale. Buick's exclusive rear air spring suspension made the Rainier the most successful at concealing ruts in the road, and the effects of Buick's "QuietTuning" could be heard in its near-silent interior. The Rainier also earned a bit of initial distinction as it was the only regular-length SUV of the bunch to offer an optional V8 engine. (The Rainier was never offered in extended-length seven-passenger form.) Finally, Buick's SUV came with the most standard equipment.

Sadly, all the extra effort didn't cure the Buick Rainier of its deepest family flaws. The combination of a high stance, high weight, a softly tuned suspension and a live rear axle penalized handling on several fronts. Handling was sloppy even by truck-based SUV standards. The Rainier's numb steering needed continual corrections to hold a straight line and its rear end felt loose and unstable in extreme handling situations. It also guzzled more gas than any modern Buick, and its interior was marred by cheap and mismatched materials, illogical controls, a lack of storage space, subpar build quality and fatiguing seats.

The Rainier partly redeemed itself with smooth and strong powertrains, competitive acceleration and a plush, quiet ride. But compared to other competing upscale SUVs, Buick's entry failed to completely deliver in the important categories of refinement, feature content and handling. For consumers shopping used midsize SUVs, we suggest taking a look at more qualified and desirable vehicles such as the Mercury Mountaineer, Toyota 4Runner or Volkswagen Touareg. Another good option is Buick's new large crossover SUV, the Enclave.

Most Recent Buick Rainier

The Rainier debuted for 2004 and received minor changes over its four-year run. Initially it was offered in CXL and CXL Plus trim levels with the six-cylinder engine producing 275 horsepower and 275 pound-feet of torque and the 290-hp (320 lb-ft) V8 available as an option. Aside from its significant increase in torque, the V8 also featured a cylinder deactivation system that saved a little fuel when cruising. Either way, a four-speed automatic transmission was standard, and both engines were available with rear- or all-wheel drive.

The following year, Buick dropped the Plus trim and the optional front seat-mounted side airbags. In their place, full-length side curtain airbags became available. In 2006, stability control became standard, the inline-6 gained 16 hp for a total of 291 and the V8 was pumped up to 300 hp.

The Buick Rainier midsize SUV was discontinued after 2007, its final model year, to make way for the vastly superior Enclave. At this point there was one well-equipped model, the CXL. Standard equipment included alloy wheels, an auto load-leveling suspension, dual-zone climate control, a CD player, power front seats, leather upholstery, antilock brakes, traction control and stability control. Major options included a navigation system and a rear-seat entertainment system.

If you're shopping for a used Buick Rainier, we'd advise confining your search to the '06 and '07 model years to ensure you get a Rainier with stability control, a feature we consider especially important given this SUV's less-than-ideal handling dynamics.

  • Love it - 2006 Buick Rainier
    By -

    I am so happy with my new truck. I went from a 1999 Tahoe to this. There is nothing that comes close to the comfort this truck offers. It is easy on the eyes and you will find your self not wanting to pull up in the garage.

  • Excellent Buy - 2007 Buick Rainier
    By -

    The interior is very nice and the seating is comfortable. It is a very quiet ride as well. There is a lot of power with the 4.2L V6. I would definitely recommend.

  • Everything I Need - 2006 Buick Rainier
    By -

    After driving a Cadillac Deville for the last 10 years the Rainier compares in features and comfort. I needed a vehicle with the luxury of a Cadillac and towing capacity of a truck. Behold the Rainier is the perfect vehicle for my needs.

  • My "BIG" SUV - 2006 Buick Rainier
    By -

    I have been a 2006 SUV Buick owner for about 7 months now. Overall I am disapointed with the performance with the V6 291hp AWD, Hits slight inclines with a lot of difficulty, have to shove into 3rd gear to climb hills. Comfort wise, it is OK for me for my medium frame and build. Not very good on gas, get about 17-18 on streets, look at the mileage before you buy and factor in your daily/weekly/monthly cost. It is a sleek sexy car for the average person, The quality of the car is "huh" OK. The doors are "very" heavy and make a lot of noise when opening and closing, I tried oiling and greasing them, but to no avail. The lift mechanism for the hydraulics, when adjusting for heavy loads, is very noisy.

  • Wouldnt You rather drive a buick! - 2004 Buick Rainier
    By -

    I purchased my Rainier 12/06. Have driven it about 600 miles so far. Love it! I wish I had gotten it alot sooner. I have driven, and was willing to buy the new 06 Explorer, but after driving it and deciding it wasnt all what they said, I decided to try a Pathfinder. Too expensive. So I decided to try a TrailBlazer, Envoy and such. Drove the Buick and was sold! I love the power, quietness, options and such. Explorer comes with one power-point, where Buick has three. Also if you go to U-haul they wont rent you a trailer if you have a Explorer. Enough said about the tranny.

  • A New SUV Owner - 2005 Buick Rainier
    By -

    Easy to drive and maneuver in parking lots. Plenty of power in the 6 cylinder engine. Doesnt cruise on open roads as well as the LaSabre I owned previously but is much better on mountain roads. I like the inside comfort and controls. Plenty of storage space in the rear. Very smooth and quiet ride.

  • Great Value - 2004 Buick Rainier
    By -

    Smooth and quiet ride. Great truck on a long trip. Love all the options. Great value. Too bad Buick does not know how to market this vehicle as I do not fit the over 50 age group who would "rather be driving a Buick". I bought the truck by a chance viewing on the car lot.

  • Not a quiet cabin ride - 2007 Buick Rainier
    By -

    The 2004 Rainier that I had rode a lot quietier. This 2007 has a wind noise starting at 35 mph and gets louder. I have had it back to 2 different dealers for this problem as suggested by GM motors. They can doing nothing at this time because of no recalls or service bulletins. It seems to me that it is the door seals on the back. Sounds like the back window is open a little on both sides

  • Amazing SUV! - 2006 Buick Rainier
    By -

    This car is the best! My husband and I bought it for the room, safety features and comfort. We will be starting a family soon and this car is great. My friend bought one because she loved driving in mine so much.

  • Love my Buick - 2005 Buick Rainier
    By -

    Ive had my Buick for four months now and I really fell in love with it. It is the most comfortable SUV that I have ridden in. The ride is like my cousins Cadillac.
