2018 Gmc Sierra denali problems
Denali is a nameplate used by GMC for its highest trim level on its vehicles. Vehicles with the Denali trim option carry list prices up to 47% higher than base models. Prices range from $38,600 for GMC Terrain to $109,410 for a top-of-the-line Yukon XL Denali (as of 2023).
The Denali nameplate is often used as an insignia or status symbol, and in particular is popular as a less costly alternative to the Cadillac marque. The Yukon Denali line typically represents 40% of Yukon sales in both units and dollars. In 2013 it sold more than 75,558 units of the Denali brand, which accounted for 20% of GMC's sales, making it one of GM's most successful sub-brands.
History
The Denali nameplate started as the top-of-the-line version of the GMC Yukon for the 1999 model year. It was also GM's first attempt to go after sales from the new-for-1998 Lincoln Navigator. At the time of its introduction. General Motors decided to give Cadillac its own luxury SUV so the Denali's exterior was shared with the 1999 Cadillac Escalade, with only the front fascia and lower side body panels differing from the standard Yukon. Although the Yukon was redesigned alongside the Chevrolet Suburban and Chevrolet Tahoe in 2000, the Yukon Denali, Escalade, and Tahoe Limited/Z71 retained their GMT400 base design.
The "Denali" brand was derived from the native Alaskan Athabaskans / Koyukon people's name for the tallest mountain in North America. It is also the name of the Denali National Park and Preserve that surrounds the mountain, as well as Denali State Park.
