While driving my 2005 GMC Envoy my speedometer will stop working and register as 0 mph even when I am moving. It also has shown me travelling at a much higher speed at times. There are many issues with this that I've found while searching the web. It is unnerving and dangerous to not know the speed you are traveling. I have started to use a gps system when I drive to show my speed.

Accelerating while entering a freeway, took foot off the gas and the vehicle continued to accelerate. Applied brake but vehicle continued to accelerate. Put vehicle in neutral to try and slow down and again applied brake. Vehicle began to spin to the right and we hit the guard rail, hitting the passenger rear bumper and the driver's side front bumper. Side air bags deployed. Car spun into the middle travel lane and began to spin around. Car was slowing down and was able to turn car off. Fortunately no other cars were involved. An off duty sheriff's deputy stopped and said he noticed smoke and thought the car was on fire but no fire occurred. When state police arrived they asked us to move the car to the break down lane. Was able to put car in reverse and backed car to breakdown lane. Tried to put car in drive but car wouldn't go forward.

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.

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.

I bought a 2005 GMC Envoy used but in good shape. After about 5000. Miles the speedometer started to read 120 mph. It reset itself a couple of times but now it's completely stuck at the 120. Also the gas gauge sometimes works and sometimes it doesn't. I can fill it up and it will ding and the light comes on and it won't show a drop of gas on the gauge. Then a day or so later it will be fine. Also the check engine light is on. I replaced the gas cap since the owners manual said it could be a faulty gas cap. It helped for a few days but it's back on. After reading all these reviews and complaints I'm sorry I bought it. I don't have the money to keep getting it fixed. It cost a $100 for the dealer just to hook it up so they could tell me it needed a speedometer head.(?) that will only cost $468. But that won't fix the check engine light or the gas gauge. I'm worried that I'll get a ticket because the speedometer doesn't work or run out of gas when the gas gauge isn't working.

While driving I looked down to check my speed and was surprised to see the speedometer reading 120 mph. While doing research on the internet I found there was a class action suit that was settled in 2008 because of this problem however, my vehicle was not listed as covered in the suit. I feel it should be covered as my vehicle is experiencing the same problems as the ones covered in the settlement. Under the settlement agreement GM would provide the cluster at no cost to me and I would be responsible for the labor cost.

The fuel gauge is inoperable due to the failure of the fuel sending unit. This is a common issue in the 2004 -2007 GMC Envoy, Chevy trailblazers and Buick ranier. I know at least 4 other people who have experienced this issue. The dealer states that this is not a class action issue but to many comments are on the internet. The vehicle will stall at intersections and parking lots when proceeding through the intersection after being stopped. I contacted GM customer service and they stated that this is not a recall issue with the GM products. GM should be recall all vehicles and replace the fuel sending units at no charge or a reduced charge(cost of part or labor whichever is the least cost to the owner). The government has bailed them out now it is time for GM to do the right thing. Also the instrument cluster stopped working correctly also and this resulted in speeding tickets. I have replaced with a remanufactured instrument cluster at the cost of $150 vs $600 with the local GM dealer.

Sporadic failure of speedometer - registers correctly one moment, or may read 30 mph or 0 mpg when keeping with the flow of traffic on the interstate. While this does not occur each trip, it does occur several times each week. Fuel gauge malfunction - reads one-half tank at 179 miles; 20 miles later reads one-quarter tank. Issues "fuel level low" warning after refueling and for next 3 to 4 times vehicle is started headlights dim briefly when accelerator is released. Frequent need to replace exterior lamps the problems first manifest in the need to repeatedly change brake and taillight bulbs, and the dimming of the headlights, which continues. Then, sporadically, the speedometer stopped functioning, or only registered a fraction of the speed the vehicle was traveling. After that, at start up, the "fuel level low" warning, which activates when the vehicle determines it has fuel to travel 40 additional miles, started to chime when there was more than one-half tank of fuel. The warning also now issues whenever the vehicle is refueled. The potential failure of the exterior lighting system presents a clear hazard to the occupants of the vehicle and others - the driver wouldn't be able to see where he is going, and other drivers wouldn't be able to see the vehicle heading toward them. The fuel system issues could lead to unexpectedly running out of fuel, creating the potential for a disabled vehicle or its driver being hit by another. In addition, depending on the cause of the malfunction, the vehicle could be susceptible to fire. Without a functioning speedometer, the driver can easily travel too fast for conditions, or endanger himself and others in a construction zone. Currently, until the sporadic problems become regular, the garage will not fix the vehicle.

Item 1: fuel gage located on instrument panel reads empty after tank is filled to maximum, light goes on indicating tank soon to be empty, after fuel is added gage fluctuates often from empty to 3/4 filled then 1/2 tank then back to empty reading which makes me constantly refueling tank.this problem occurs while vehicle is in operation..item 2 speedometer fluctuates reading 80 miles in speed actually no such speed is being driven then returns to zero miles continues to move so erratically. Dealer service advisor stated problem is the fuel sensor suppressor located in the fuel tank, states tank must be dropped down during repair, recommended should replace fuel pump now since tank was accessible good opportunity in replacing also this item and I would be covered with lifetime warranty in future if need of repair. Fuel pump price $480. I declined repair only fuel sensor/suppressor, check speedometer gage. Service advisor stated this item was not recalled or covered, this financially sets me back now since on a set income.this because myself a disabled vietnam veteran. Hope no more problems would be found on my vehicle these. This part alone would cost $380 not including repair charges. Vehicle was in for maintenance service oil change, radiator flush, tune up, transmission service. Personally always have recommend GM vehicles/products to all associates, family, friends & acquaintances. I own a classic original 1947 Pontiac 8 flathead, 4 door streamliner.today just disappointed with these issues may have resulted to accidents leading to bodily injuries, or fatalities. Complaints have been filed with this model among other issues.& concerns. Would appreciate investigation the many complaints on file thru years 2001-2008 make & models also set as priority before any future accidents or deaths occur. With quick response & action GMC can avoid many bad reactions against their history of great quality and it's excellent commitment to customer satisfaction.

The gas gauge stopped working and shows that the vehicle is on empty. The "low fuel' indicator on the dash will blink randomly and "ding" to draw my attention to it. The gas cap was replaced a week later but the problem has not been resolved. It continues to read "empty." Since then the speedometer has also stopped working. The speedometer hand has completely dropped below the 120 mph mark, although for a few weeks it would register that I was driving much faster than the speed of traffic around me. Moreover, it would register 30 mph when the vehicle was completely stopped. Yet, it has since stopped working altogether. The vehicle has also recently stalled in reverse and several times has surged/accelerated quickly when I am driving slowly and push the gas pedal to accelerate. I have an appointment with the local GMC dealership and have called the national GMC dealer to document my complaint(s).

2005 GMC Envoy denali w/37,800 miles. On several occasions, while completely stopped, the vehicle would slightly lunge forward as if going to accelerate although the brake was engaged. When local GMC service dept. Was called by owner to inquire about problem, service tech said he had no reports of such situation. The surge happened again on 10/31/08 and there was a passenger in the vehicle who also experienced the sensation. On 11/17/08 while at a complete stop, after turning wheels sharply to the right to go around a road equipment vehicle in the parking lot, upon removing foot from brake, the denali lunged forward enough to bump the tire of the equipment vehicle and then it accelerated as if the cruise control was activated. There were no brakes when an effort was made to stop the vehicle. Steering of vehicle was hard due to power steering failure. Vehicle jumped upon a curb, driver forcefully turned steering wheel to avoid hitting a brick building as acceleration was still ongoing. Vehicle crashed through a steel garage door and continued until it crashed into a retaining column at which time the motor was turned off. The impact of the collision could be felt up to the second floor of the building. The driver was wearing a seat belt. The onstar services did not initiate response to driver despite the fact that the front bumper of the vehicle was no longer attached to the vehicle, nor did the driver airbag deploy upon impact. Vehicle was towed away from the scene. Driver was transported to hospital by ems for injury evaluation. Several witnesses described incident as "vehicle out of control". updated 10/29/10
