2003 Buick Rainier problems
The Buick Rainier is a mid-size luxury SUV that was manufactured by General Motors and marketed by Buick for the 2004 to 2007 model years. It was named after Mount Rainier, and — along with the Saab 9-7X — served as the replacement for the Oldsmobile Bravada.
History
The Rainier was introduced on July 28, 2003, for the 2004 model year, in a 5-door, 5-passenger configuration, yet was one of only five GMT360 SUVs to offer a V8 engine — along with the GMC Envoy Denali, Isuzu Ascender EXT, Saab 9-7X 5.3i and Aero, and Chevrolet TrailBlazer LT (optional) and SS. Both rear and all-wheel drive models were offered. The only trim available was CXL. An available Sun, Sound and Entertainment package for 2005 (previously called CXL Plus,) added a power sunroof, better Bose stereo, and XM Satellite Radio. For the 2004 model year only, there was a CXL Plus trim level, this became the aforementioned Sun, Sound, and Entertainment package for 2005. A touchscreen DVD-based navigation system was also available with the CXL Plus/SSE package. The 5.3 V8 was also available with the "V8 Power Play" package, which added a "V8" designation to the "RAINIER" script on the left side tailgate.
Buick also debuted the QuietTuning sound insulation on the Rainier, where a vehicle's sound dampening featured triple door seals, side acoustic laminate glass, and thicker sound-absorbing pads on the hood and firewall. The Rainier was the first production vehicle to use side acoustic laminate glass.
The Rainier was discontinued after the 2007 model year and was replaced by the Buick Enclave in 2008. GM ended production of the related Chevrolet TrailBlazer, GMC Envoy, and Saab 9-7X after the 2009 model year.
The Insurance Institute for Highway Safety (IIHS) gave the 2004 Rainier an overall Marginal score for front impacts while the 2005 and newer models are given an Acceptable score. In side impacts the Rainier was given an overall Marginal score with side airbags present.
