2007 Gmc Denali problems and complaints

2007 Gmc Denali problems

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 2007 Gmc Denali problems

The 2007 GMC Denali, like any other vehicle, has its share of common problems. This article will discuss some of the most frequently reported issues based on complaints from owners of this car.

Firstly, the EVAP Vent Valve Failure is a common problem in the 2007 GMC Denali. This issue is related to the Evaporative Emission Control System (EVAP), which prevents fuel vapors from escaping into the atmosphere. When the EVAP vent valve fails, it can cause a check engine light to turn on, displaying codes P0449 or P0455. While this problem may not affect drivability, it is essential to address it to maintain the vehicle's overall performance and prevent further damage to the EVAP system.

Secondly, the Throttle Body Failure is another common issue in the 2007 GMC Denali. This problem is related to the sensors inside the throttle body, which can fail and give the computer an inaccurate reading. When this happens, the engine reduced power light with code P2135 may turn on. Cleaning the throttle body will not fix the problem; instead, the sensor or the entire throttle body unit needs to be replaced.

Thirdly, the Front Wheel Bearing Failure is a common problem in the 2007 GMC Denali. This issue can cause a loud grinding noise from the wheel, similar to an airplane, which may increase when turning. If not addressed promptly, this problem can lead to more severe damage to the wheel bearings and the vehicle's overall performance.

Lastly, the Active Fuel Management (AFM) Issues are common in the 2007 GMC Denali, particularly in the 5.3 V8 engines. The AFM system is designed to save fuel by shutting down cylinders when the vehicle is under light load. However, this system has been known to cause issues with the lifters, which can lead to engine failure. If the vehicle has AFM, it is recommended to avoid it or consider replacing the lifters.

In conclusion, the 2007 GMC Denali has several common problems, including EVAP Vent Valve Failure, Throttle Body Failure, Front Wheel Bearing Failure, and Active Fuel Management Issues. It is essential to address these problems promptly to maintain the vehicle's overall performance and prevent further damage. Regular maintenance and check-ups can also help identify and prevent these issues from occurring.
