After driving approximately 20 miles on cruise control I tapped the brakes to disengage the cruise control. The vehicle dramatically lost power and the check engine light came on. I was able to avoid other traffic and pull over on the freeway, I then drove off the freeway on the shoulder and into the nearest gm dealer at maximum speed of approximately 30 MPH. The problem was diagnosed several times resulting in rewiring of the throttle body connector and finally replacement of the throttle body after the third incident of the same issue. Loss of power and unable to proceed at more than about 30 MPH.
2006 GMC Envoy Denali engine complaints

In the rear compartment of my 2006 gmc envoy denali there is a compressor. There must be a leak because my car looks like a low rider in the morning until I start it and the compressor comes on and in about 3 or 4 minutes it is back to it's normal drivable height. Has there been this problem with anyone else and is there a recall to fix this problem?
My gmc envoy denali 2006 uses up to 2 to 3 quarts of oil in a 30 day period. I have no leaks or exhaust problems. It finally collapsed a lifter and push rod. Says there is no notice or recall, but the is the same engine they used in the 2003 pontiac, they did recall those motors. Does any one have some help for me?
Reduced power light came on when on the highway. Almost got hit by a semi. This has happened many times. The engine has only 8k miles since engine was replaced under warranty.
2006 envoy denali. Consumer writes states gas needle stopped functioning *tgw the consumer stated the gas needle began to fluctuate in the beginning and since that time, the needle has been stuck on empty, and the engine light illuminated as a result. In march of 2009, when the consumer stared the vehicle, it sounded as if there was something metal tumbling around under the hood. Upon inspection of the vehicle, it was determined the engine needed to be replaced. On june 10, 2010, the vehicle would not start and had to be towed to the dealer. An inspection revealed a starter was needed. Also, an alignment was done and the rear brake light was replaced. On june 12, 2010, the vehicle would not come out of park. After 25 minutes and over 50 attempts, it finally came out of park. The consumer drove to the dealer, but they were unable to find a problem. September 2010, the consumer noticed the rear of the truck was sitting very low. The rear end air suspension needed to be replaced. The air condition randomly worked. There were times where the air would just start blowing and no buttons were pushed. Also, the defroster stopped working. The consumer continued to experience problems with the vehicle not coming out of park.
Fuel sensor failure in the gas tank. Causing the fuel tank to read empty when full, causing the SUV to stall when the tank is full, causing the check engine light to come one. This is a safety issue.
