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.

Common 2009 Gmc Yukon denali problems
The GMC Yukon Denali 2009, like any vehicle, has its share of common problems based on complaints from owners. Here are some of the most frequently reported issues:
- Throttle Body Failure: The throttle body, which regulates the amount of air entering the engine, can fail and cause the engine to run poorly or not at all. This issue can trigger a check engine light with code P2135. Cleaning the throttle body will not fix the problem. The best solution is to replace the sensor or the entire throttle body unit.
- Front Wheel Bearing Failure: The front wheel bearings can fail, causing a loud grinding noise from the wheel that sounds like an airplane. The noise may increase when turning. This issue can be diagnosed by shaking the tire in and out from the 12 and 6 o'clock position. If the wheel bearing is bad, it will make a grinding or clicking noise. Replacing a wheel bearing requires removing the wheel, hub, and brake assembly.
- Suspension Problems: The GMC Yukon Denali 2009 has an active load-leveling air suspension that can wear down over time. This can cause nose dive, where the front of the car dips down when braking, causing the rear end to elevate. It can also cause uneven tire wear, poor ride quality, and difficulty steering. These issues can be diagnosed by looking for warning signs such as the service ride control signal, unusual noises from the wheel, sagging or leaning to one side, poor ride quality, uneven tire wear, abrupt sway, instability at high speeds, and difficulty steering. These issues can be caused by excessive wear, punctures, or interconnected parts.
- Tail Light Assembly Failure: The tail light assembly is the most common part to fail in any Yukon model year, with an average mileage of 60,000 miles. This issue can cause moisture to form on the lens or the light to stop working altogether. Replacing the tail light assembly requires removing the malfunctioning one and installing a new one.
- Interior and Accessories Problems: Many Yukon owners have reported issues with the accessories and interior parts, such as loud noises from the dashboard, climate control panel, console phone, front camera, and USB charging ports refusing to work. The 2007 and 2015 model years have drawn the most complaints in this category.
In conclusion, the GMC Yukon Denali 2009 has several common problems that owners should be aware of. These issues can range from minor cosmetic problems to major mechanical failures. Regular maintenance and inspections can help prevent these issues from occurring or catch them early before they become more serious.
