2007 Gmc Envoy denali problems
The GMC Envoy is a mid-size SUV manufactured and marketed by General Motors for the 1998 to 2009 model years over two generations. Adopting a nameplate used by GM Canada, the Envoy was a rebadged variant of the Chevrolet TrailBlazer, Oldsmobile Bravada, Buick Rainier, Isuzu Ascender, and Saab 9-7X.
General Motors assembled the model line at its Moraine Assembly (Moraine, Ohio) and Oklahoma City Assembly (Oklahoma City, Oklahoma). Both facilities were closed by 2008, leading to the discontinuation of the model line. The Envoy was not directly replaced in the GMC model line as General Motors transitioned its smaller SUVs to unibody-chassis designs, introducing the smaller GMC Terrain and larger GMC Acadia.
First generation (1998–2000)
The first generation GMC Envoy was introduced for the 1998 model year. Introduced a year before the Chevrolet TrailBlazer, the Envoy was the highest-trim version of the GMC Jimmy SUV. In line with the Oldsmobile Bravada, the Envoy was fitted with a leather-trim interior, floor-mounted shifter, and a largely monochromatic exterior with aluminum-alloy wheels. In line with the TrailBlazer and the Bravada, the Envoy trim was offered only in the five-door version.
The Envoy had many extra features not available on the regular Jimmy 4-door including: a remote trunk release, heated driver's and passenger's seats, a Bose sound system, and High Intensity Discharge headlights. Optional features included: a power sunroof, a panic alarm, an anti-theft system, and a power front driver & passenger seat.
GMC ended sales of the first generation Envoy after the 2000 model year as the division adopted the name to replace the entire Jimmy SUV line for 2002.

Common 2007 Gmc Envoy denali problems
Based on the complaints from owners of the 2007 GMC Envoy Denali, several common problems have been reported:
- Cylinder Deactivation System Failure (DOD System):
- The 2007 GMC Envoy Denali with the 5.3 liter V8 engine has a cylinder deactivation system called Displacement on Demand (DOD). This system shuts off half the cylinders during lower speeds to improve fuel efficiency. However, after around 150,000 miles, lifters in the system can fail, leading to engine issues. The main causes are related to oil pressure and quality, where low oil pressure or dirty oil can cause the lifters to malfunction. Owners often opt to disable or tune the system to prevent future issues.
- Rear Main Seal Leak:
- A common problem with aging GMC Envoys is a rear main seal leak. This issue requires a labor-intensive fix involving pulling back the transmission to replace the seal. It is a costly repair, typically taking around 10 hours of labor. While some owners experience minor leaks, addressing this problem is crucial to prevent further damage to the vehicle.
- Throttle Body Failure:
- Owners have reported issues with reduced engine power, stalling, and lack of acceleration, even after replacing various components like spark plugs and sensors. In many cases, this is caused by a dirty throttle body. Cleaning or replacing the throttle body and wiring harness can resolve these symptoms. Regular maintenance, such as cleaning the throttle body, is recommended to prevent this problem.
- Transmission Issues:
- The 4L60E transmission in the GMC Envoy Denali has faced reliability concerns. Some owners have reported transmission slipping and harsh shifting, particularly in higher mileage vehicles. While rebuilding or replacing the transmission is an option, it is essential to address these issues promptly to avoid further damage to the vehicle.
These common problems highlight the importance of regular maintenance and prompt attention to any issues that arise with the 2007 GMC Envoy Denali. Owners should stay vigilant, especially as the vehicle ages, to ensure its continued reliability and performance.
