About Buick Rainier

The Buick Rainier is a luxury crossover SUV that was produced by General Motors and sold under the Buick brand during the model years 2004–2007. It is classified as a mid-size SUV. It was a replacement for the Oldsmobile Bravada, and along with the Saab 9-7X, it was given the name Mount Rainier after the mountain that inspired its creation.

The Rainier was first shown to the public on July 28, 2003 for the 2004 model year. It had five doors and could seat five people, but it was one of only five GMT360 SUVs to offer a V8 engine. The other four were the GMC Envoy Denali, the Isuzu Ascender EXT, the Saab 9-7X 5.3i and Aero, and the Chevrolet TrailBlazer LT (optional) and SS. There were options for both rear-wheel drive and all-wheel drive in the lineup. A superior Bose stereo system and XM Satellite Radio came standard on the upscale CXL trim level. There was a CXL Plus trim level available with a touchscreen navigation system for the 2004 model year only. This level was only available.

Additionally, Buick introduced their QuietTuning sound insulation system on the Rainier. This system included thicker sound-absorbing pads on the hood and firewall in addition to triple door seals, acoustic laminate glass, and enhanced sound dampening on the vehicle’s doors.

After the 2007 model year, production of the Rainier was terminated, and it was succeeded by the Buick Enclave the following year (2008). After the 2009 model year, General Motors pulled the plug on manufacturing of the related Chevrolet TrailBlazer, GMC Envoy, and Saab 9-7X.

When it came to frontal impacts, the Insurance Institute for Highway Safety (IIHS) rated the 2004 Rainier as having a Marginal overall score, but it rated the 2005 model and newer models as having an Acceptable score. With its side airbags, the Rainier received an overall score of Marginal for its performance in side impacts.

The Rainier debuted with two engines: a standard LL8 4.2 L (256 in3) I6 producing 275 hp (205 kW) and an optional LM6 5300 5.3 L (323 in3) V8 producing 290 hp (216 kW). A new LH6 V8 with Active Fuel Management was introduced in 2005, increasing output to 300 hp (224 kW). The I6 gained 291 horsepower in 2006.
