While in motion only, a engine light accompanied by a reduced engine power engages making the vehicle unmanageable to response and cause the vehicle to stall.

While driving the Envoy at about 45 mph, a warning light saying "reduced engine power" came on suddenly, the car dropped down to about 20 mph, and that continues to occur. I can turn off and restart the car, but the problem returns within a minute after driving it again. I started investigating what that means online, and, as with anything else on the internet, I see many opinions, guesses, and possibilities. Could be a bad sensor, bad throttle control, bad wire connections, etc. But this much appears clear: (1) it is a GM problem, and a very, very common one. (2) it is a dangerous problem. This seems pretty obvious - the car suddenly loses speed and evidently sometimes stalls out altogether. But hearing about so many other people's scary experiences just confirms this. (3) it can be difficult and expensive to diagnose and fix. When I think of these facts, coupled with GM's recent history, I immediately think "recall." This certainly appears to be an appropriate situation for a manufacturer to step in and fix the issue before more people get angry with GM, get hurt, or get killed. I called the dealer who sold the car (I am the second owner), in columbus, Ohio. I was told that I can bring it in for a diagnosis for $110. (gee, thanks - wouldn't have thought of that.) the customer rep looked up the VIN and said that the vehicle was not eligible for recall or any special policy. Therefore, I am contacting you in hope that something else can be done.

Vehicle loses power drastically when going up any incline. Was going 65 and speed dropped to 35 going up slight grade hill.

: the contact stated while driving various speeds, the 4-wheel drive indicator light illuminated, and the vehicle stopped as if the brake was applied when the accelerator pedal was released. Also, a smell was coming from the brakes and the vehicle accelerated without warning. The vehicle was driven to the dealer who determined the transfer case control module needed to be replaced.

We purchased new vehicle October 2001 and within 4 months began experiencing problems beginning with a noise within the steering wheel. Dealer technician replaced defective airbag module. The next month, my new Envoy has been to the dealer 4 times for the same problem of 1) wind and/or whistling noise at speeds above 45mph, 2) "vibration" noise coming from transmission when vehicle reaches 3rd gear, 3) when vehicle has reached 3rd gear and previous noise begins, there is also a vibration felt in the acceleration pedal. On the first trip to dealer for these problems, technician only agreed with the wind noise. Discovered the front side mirrors were the cause. Replaced both mirrors---problem still exists, however, he can't hear them. Explained it was the nature of the vehicle. He also repaired the weatherstripping which had "fallen off" the right rear door. He advised that he did not hear any noise in the transmission area or in the gas pedal. We took to another dealer who had a technician test drive the vehicle and advised that there was both a noise in the area of transmission and a vibration in the gas pedal. Returned to the dealer who originally was doing repair work and had him ride with me. At this time, he heard the noise I was complaining about and advised that it was coming from the heat shield at the catalytic converter. Made an appointment for repairs, picked up the vehicle and later the same day, the noise returned. Took vehicle back, technician said he didn't hear any more noises. Waited 2 weeks, made another appointment to return vehicle for right rear door "rattling", and "heat shield" noise which had become non stop. At this time, they replaced the weatherstripping on the door and again adjusted heat shield by making a "cushion" so that it would not vibrate against the exhaust manifold. This did not resolve the problem, as it still "vibrates" so as I can still feel stress through the gas pedal on the transmission when reaching speed.*
