GMC Acadia
The GMC Acadia is a Crossover Utility Vehicle from GMC. The first-generation GMC Acadia shared the GM Lambda platform with the Chevrolet Traverse, and Buick Enclave. The Acadia went on sale in 2006 as a 2007 model in the United States, Canada and Mexico. The Acadia replaces three of the 7- or 8-seater vehicles on the Pontiac–Buick–GMC dealership network, the midsize GMC Safari van, the GMC Envoy, and the Pontiac Montana SV6 minivan for the domestic market. As of 2009, the Lambda vehicles have replaced the Buick Rainier, Buick Rendezvous, Buick Terraza, and the GMC Envoy XL and then subsequently the GMC Envoy, Chevrolet TrailBlazer and the Isuzu Ascender. A Denali version of the Acadia debuted in 2010 as a 2011 model. In 2016, the second generation Acadia was repositioned as a mid-size crossover utility vehicle in order to compete within the growing midsize SUV market against the likes of the Ford Explorer and Jeep Grand Cherokee.
First generation (2007–2016)
The Acadia represents GMC's entry-level truck-like CUV and is the first unibody vehicle from the marque. It is also GMC's first front-wheel drive passenger vehicle.The Acadia has seating for eight and either front or all-wheel drive. With a towing capacity, the Acadia slots between the GMC Terrain and the Yukon. The Acadia is the mid-priced Lambda model between the Chevrolet Traverse and Enclave.
In December 2006, all production and sales of the Acadia were temporarily stopped due to the engine mounts not having holes drilled to release accumulated water, as well as an issue with potentially faulty rivets in the load floor just forward of the vehicle's rear hatch. The assembly process was quickly adjusted, and dealership sales of the vehicles had resumed within days of the notice.
The first-generation Acadia was sold alongside its second-generation replacement as the Acadia Limited.
