Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

The speedometer does not function properly anymore. This is a recurring problem in GMC Envoy, but GM will not acknowledge nor fix the issue. Speedometer currently shows I'm doing 60 mph while parked. This is a safety issue because drivers don't really know how fast they are going......

The speedometer stopped working and reads 120 miles an hour no matter how fast I'm traveling. I currently use my gps to watch my speed. This is unsafe and this is a on-going compliant for many consumers. GM should be aware of this dangerous and irresponsible assemble of this vehicle.

The speedometer stops working after about two hours of driving. It goes to zero. It sometimes starts again if the vehicle is stopped and started again, but it will quit working if a long drive continues. It works perfectly when driving around town on short trips. The service bulletin apparently says to "clean ground connection". however, this did not fix the problem. I am told I need to have speedometer replaced at a cost of over $600.

I purchased my Envoy approx. 1 year ago. I have 105,000 miles on it currently. My speedometer would get stuck at 50 mph but would seem to always end up fixing itself. Now it is pegged at 120 and has been that way for 2 months. # 5 on my ac/heat blower is not working. My engine light is on. My windshield wipers turn on every time I start my car. I can not turn them off, usually after about 30 wipes it will turn off. This is very frustrating to me. As I am researching these problems on the internet, hoping to find some sort of recall, I find many other Envoy owners with the same problems!!!! I really feel that GMC should be responsible for this as many people are in this situation. I have to say with this many problems, it's the vehicle not the people and I think GMC needs to back their product and take care of these issues.

The speedometer is reading incorrectly. For example, if going 25 mph, it shows 70mph. It does not show the same speed each time either. Never goes to 0 mph. This problem just occurred one day.

The speedometer on my 2005 GMC Envoy has stopped working properly & also the thermostat gauge & the gas gauge. This is a common problem among Envoy owner's & is a safety issue. The instrument cluster needs to be recalled & replaced.

Envoy 6-cyl

I was driving down the highway when I noticed that the speedometer indicated that I was going 90+ mph. I slowed down to the point that people were passing me in a 65mph zone and my speedometer was indicating 60 mph. I pulled over and stopped the vehicle and the speedometer needle continued to erratically go up and down.

Fuel gauge does not go above 1/8 tank. Speedometer "sticks" usually at highway speed and when stopped does not return to zero then when vehicle is moving again the new speed is accumulating on "stuck" speed. Sometimes speedometer "sticks" before reaching steady speed and when vehicle is stopped the reading is below zero in this scenario when the vehicle is moving again the "registered" speed is below actual speed. As I drive 1,000 miles a week, it is quite important to know how much fuel I have in my tank and of course how fast I am traveling.

The speedometer on my 2005 Envoy is nolonger working...the problem seem to be common with Envoy owners because we have an entire forum on it I have complained to GMC and no avail...I tried to trade the car but was offered way less than fair trade value because the speedometer is not working I hope I can get some help from someone..I can not afford to keep taking the car back and forth to the dealership.

  • 90,400 miles
Driving down the road I glanced to check my speedometer and saw it registered about 100 mph. I was only going about 40. The speedometer continued to climb and went below the highest registered number, which is 120, and that's where it now sits apparently for good. Now I cannot tell my speed. The needle remains buried below 120 mph and does not move at all no matter what speed.

  • 97,000 miles
The speedometer does not accurately record the speed while traveling for my 2005, GMC, Envoy, slt model. It will indicate that I am traveling 20 mph or even 0 while on the highway and seems to increase my rpms while malfunctioning. This has caused several tickets as I can not personally track how fast/slow I am going while driving. This malfunction happens everyday. My oil gauge is also unable to read, it never moves and reads under the start of the meter (South) at all times, even when the vehicle is not started.
