Problems with 2004 GMC Envoy XL ELECTRICAL SYSTEM

During normal driving conditions and with no warning both the speedometer and tachometer topped out and have not worked since. *tr

This past weekend 08-23-08 and 08-24-08. the analog dash cluster went out on my 2004 gms envoy. when it went out i mean completely out no tach, speed or and or the gauges worked. this happened while i was driving. i took the vehicle to the dealership right away. it was checked and confirmed that the dash cluster was not getting any power. this can be a safety hazard for the reason being if it where to happen while driving like it did to me. it could be a contributing factor in an accident. not know how fast one is going can be very dangerous. there is a new dash cluster on order which should be installed by wednesday 08-27-08. *tr

The tachometer and speedometer do not work. while driving to work in a construction zone, my speedometer began malfunctioning. while traveling with other commuters, my speedometer read that i was traveling 85 mph. the tachometer has been out for several months. after calling the dealership, they informed me that this is common in my vehicle. *tr

My 2004 gmc envoys speedo is not working correctly. the fuel gauge is acting up too. *tr

After getting an oil change the technician went to pull the car out of the bay and the car just died. it appeared first that the battery may have died. there was no power at all. next after letting the vehicle sit for a minute we attempted to turn on the ignition and all the gauges went crazy, registering as if i was driving. then as in the another complaint, upon attempting to start the vehicle, all the dash board warning lights and turn signal indicators came on and stayed on. all the gauges started acting erratically and all the needle indicators started jumping at random. the next time i tried to start the vehicle again the vehicle did the very same thing as mentioned above (gauges acting erratically, etc.). i attempted to start the vehicle several more time each time with the same result. prior to this experience the oil gauge had stop registering and had malfunction about one year earlier. after my favorite mechanic came to rescue me hot wired the fuse box to allow for me to drive the vehicle home. he said that the fuses were not getting the 12 volts need to operate the vehicle. i'm now waiting on the diagnosis. *tr

We were just driving down the road when the speedometer suddenly read 120 mph. we were driving about 40 mph. the speedometer is now stuck at that position, 120 mph. *tr

I had to have the instrument cluster replaced for a faulty speedometer. *tr

2004 envoy - instrument cluster. *tr

Speedometer stopped working properly. $500 to replace. gm will not help, even though they are aware of the defective units that are on the streets. they have recall on pickup trucks for same problem. *tr

Speedometer on 2004 gmc envory started acting up and would read twice the actual speed of vehicle. then it froze at 80 mph. it stills is not working. it jumps around all the time now. *tr

The speedometer on my 2004 gmc envoy xl malfunctioned. its readings are very erratic and do not correspond at all with the speed of the vehicle. for example, readings of 10 mph while driving on the interstate with the flow of traffic and 100 mph while stopped at a traffic light. the readings vary anywhere from o mph to past 120 mph and are completely unrelated to the vehicle's speed. this failure occurred suddenly. the first sign was the speedometer sticking at 10 mph even as i accelerated; it then began the erratic behavior mentioned above. as a consequence, it is impossible to determine the speed at which this vehicle is traveling. this was especially concerning to me since this failure occurred as i was traveling home from indiana to south carolina with my wife and 3 children in the vehicle. this occurred yesterday and has not been repaired at this time. *tr

Electrical problems. i have had both rear tailgate sensors go out at the same time. i have the speedometer acting erratically off and on off and on. i have had the starter switch go out twice. *tr

Driving down the road our speedometer went haywire and then quit working. i called gmc and they said our vehicle is not covered under the current vehicles that are covered and that our vehicle has not been reported as a vehicle experiencing difficulties. we own a gmc 2004 envoy xl.*cn

The speedometer/tachometer in my 2004 gmc envoy read inaccurately. the needles read way off of where they should be (ie. reading 45 mph at idle and tach at 8,000 rpms at idle). *tr

Speedometer is erratic often 30 to 80 mph off and will not return to 0 mph when stopped. currently it reads above 120 mph and will not move up or down. *tr

The speedometer has become erratic on my 2004 gmc envoy xuv. i was told by a dealership it will require replacement in the range of 300 dollars just for parts. this appears to be a manufacturing defect that conveniently appears shortly after the expiration of the warranty. from web posts it is obviously a widespread problem that should be addressed by the manufacturer. i have recently received a speeding ticket and my inspection is due!!!!! *tr

Speedometer reading 25 mph at full stop. n4180 cluster assembly was replaced. instrument panel buttons were then not working as they had previously. working on the issue with the dealer. *ak

I have a 2004 gmc envoy (under 26,000 miles). i have noticed that after the suv runs for about 1/2 hr the speedometer will display my speed being below zero. in reality i am going about 50 mph. the speedometer is being acting very erratic. is there anything the gm can do for this problem. i am in the process of talking to the dealership where i purchased the vehicle. i have read about the similar problem to other envoy owners on the internet. i have also seen the same issue in other gm brands. i think gm should recall 2004 envoys for this problem. *jb

The cluster in my car has gone out and my speedometer is no longer working up on taking it to the dealership i was informed that this is a common problem in the envoy. they stated the at least received 4 to 5 vehicles a day with the same problems. *tr

Speedometer malfunctioning, currently reading 68 mph while car is still. *jb

Erratic speedometer reading on 2004 gmc envoy, started 45 days ago and reading is different everyday. *nm

Speedometer on my 2004 gmc envoy xl slt reads incorrectly at all times. began as reading high occasionally, now it is entirely unreliable. sometimes high, sometimes low, sometimes 140mph in the driveway. *tr

Speedometer began acting up a few months ago and now it's constantly acting up. sometimes it shows me going faster than actual and sometimes it shows me going slower than actual and sometimes it just sits below zero and doesn't move at all. now the oil pressure gauge stopped working. it reads all the way past 80 and doesn't even move when i turn the vehicle off. i do not trust any of my gauges now. i cannot be assured that any of them are reading correctly. *nm

The speedometer and tachometer on our 2004 envoy xl sometimes quits working. this creates an unpredictable situation especially on long trips. *jb

Speedometer doesn't work. it will jump around and stick on any given speed and remain there. sometimes when the vehicle is restarted it will decrease 5 mph from the point at which it was last positioned. i cannot regulate my speed without the speedometer and afraid that i will cause an accident. it has not been fixed.

Own a 2004 envoy xl. speedometer stuck maxed out at 100+ mph. had to have the instrument panel replaced. quite a shock when you look down and think you are going 100. should be part of recall. *tr

Transmission not shifting correctly, abs light, brake light, emergency brake light, 4-wd drive light, heat/ac crusie control not working. found pi report, ignition switch replaced, fixed problem. *ak

Envoy not shifting properly, sounds like it is dragging, had it checked out, the dealer could not replicate problem. now when the difficulty starts the abs light, the brake and emergency brake light along with the 4wd light all come on, the blowers do not function when all the warning lights are on, nor does the air conditioning and or cruise control. i took it back to the dealership with all the problems active, initially they told me that it had 43,000 miles, it was out of warranty, but then a pi report suddenly came out so we will see if i end up paying. they did tell me however that they have a trail blazer in with the exact same problem and it took them 8 days to figure it out and that i would not be getting a loaner since i am out of warranty. i should also mention that the computer was replaced at 27,000 miles.

The one "electrical" part that controls the instruments that give the speed of the car, rpms, gas, oil, ect....all gauges do not work. there has been no recall on this yet with gmc, i have a 2004 gmc envoy and this problem started to occur right after the 60k mile mark. this is a true "danger"...i have no idea what speed, how much gas, what my engine is doing...nothing...the dealerships want anywhere from $400.00 to $600.00 to fix this problem. this is a true mechanical defect. the service manager at one of the local dealerships, said that gmc has a real problem....they have to replace this one part often. its something they see often. i want gmc to recall this part and fast...i need my gauges to work. *jb

Engine, check gadges light appears, suv stalls, radio lights and steering lights keeps failing. i have taken my 04 envoyxl into the dealership over 7 times for the same problem in which they have not yet been able to fix/resolve. my envoyxl check engine and check gadges lights keep popping on and the vehicle continues to cut off/stall the dealership has not yet fixed the problem, i have taken the suv in over 6 times for this problem. from 2004 until now 2007 the problem continues. the lights on the dash board keeps going out. they have replaced the lights at least 2 or 3 times but they keep going out. these lights are on the radio part, the buttons which operate the radio and switches the station. the panels seems to get very hot. the lights are currently out now after being replaced 3 times and now the vehicle is out of warranty. the paint on the suv is very dull and the leather on the 2nd row seat is cracking, completely worn and very cheap. i complained to the dealership 1 year after i purchased the vehicle that the leather is worn out too fast, nothing was done about the 2nd row leather seats. the paint on the exterior is dull and spotty, i complained to the dealership before the 36,000 mile warranty expired and nothing was done about the paint either. this suv is a lemon, it continues to cut off although many attempts has been made to repair the problem, i think they should buy this vehicle back since it can't be fixed. there is a defect in the electrical system since these lights on the instrument panel continues to wear out very fast and the radio had to be replaced already but the lights continues to blow out on the instrument panel and the steering wheel which also controls the radio and other components. *tr

No heat in rear of envoy gmc has no repair. *ak
