40 problems related to instrument panel have been reported for the 2005 GMC Envoy. The most recently reported issues are listed below.
Speedometer is frozen @ 70 mph.
Problem just started with no warning. Speedometer reads 60 mph while vehicle is parked with engine off. When you crank the vehicle. Speedometer indicator drops down approx. 5 mph (55 mph) then when you drive the vehicle the speedometer indicator (needle) goes past the 120 reading on the speedometer. I feel this is very dangerous because you cannot determine the true speed vehicle is really going . Vehicle odometer and trip odometer are not affected (checked by mile marker on interstate). Failure is consistence . Occurs everytime vehicle is operated. Notified dealership and they said (no recall) . Vehicle has approx 52,000 miles.
Reported earlier gas odometer broke when fueling vehicle on 2 seperate occassions, first time fixed, then again while fueling gas, it broke. Failed to mention my problems with the speedodometer. It was fluctuating all the way up, then all the way down irratically before it dropped down to the middle.
Speedometer malfunctions showing various speeds. The needle gets stuck for a moment while the car speeds up. The needle will also stay at one speed while the car slows down, thus giving no true reading of speed at any given moment.
The GMC Envoy's speedometer stopped working and GMC is aware of this issue and only solution they have is 450 + labor which doesn't guarantee the issue is resolved. . . I have researched numerous articles as well as websites where other gm victims have reported their vehicles to do the same thing. . . . The speedometer is something very important which shouldn't be a common problem, serious if not life taking accidents happen when drivers aren't able to be aware of their speed. I would hope that this complaint will follow with others and there will be some type recall that takes place.
