Problems with 2004 GMC Envoy ELECTRICAL SYSTEM

My dash panel gauges began failing one by one. my headlights will sometimes not come on after starting the car with the headlight switch on auto. a flick of the headlight switch in and off, does not make the headlights come on. sometimes they come on after driving around, and then will go off without touching the switch. now, my side brakelights will not operate correctly when the brake pedal is pressed. only the third brake light illuminates.

Front passenger seat caught on fire from the seat heater. the vehicle parked and turned off. it was parked in a high school parking lot while my daughter was in school. we contacted gmc, but they said it there was nothing they could do. there was something that went wrong for it to just catch fire. can you help us in anyway at all.

Tl* the contact owns a 2004 gmc envoy. while the vehicle was parked, the tailgate latch and motor failed. an independent mechanic diagnosed that the tailgate motor failed and needed to be replaced. the contact also stated that the air compressor failed to inflate the air bags evenly. the vehicle was taken to w-k chevrolet buick gmc cadillac (located at 3310 w broadway blvd, sedalia, mo 65301, (660) 826-8320), but was not diagnosed or repaired. the contact was informed that the vin was not included in a recall. the manufacturer was not notified of the failures. the failure mileage was unknown.

The abs light stayed on after the fact i had the breaks serviced a few years ago. the airbag light has been on for about a year. now my break light stopped working, i replaced the fuse and still not working and now the headlamps stopped working. they only work on high beam.

Tl* the contact owns a 2004 gmc envoy. the contact stated that the vehicle's electrical system stopped the vehicle from starting. there were unknown warning indicators illuminated at the time of the failure. the vehicle was towed multiple times due to failing to start. an independent mechanic stated that there was a cable disconnected, but the vehicle was not repaired. the failure occurred again and the vehicle was taken to jessup auto plaza (68-111 e palm canyon dr, cathedral city, ca 92234, (760) 328-9999). the technician was unable to locate a failure and the vehicle was restarted. the vehicle was not repaired and the failure occurred again. the manufacturer was not contacted. the failure mileage was 72,338.

I was in the highway tail lights weren't working in was headed to idaho due to that im still in north dakota also like a month ago i was pulled over in the city for no back lights it's happen 4 or 5 times two on a 15 hour road trip.tailgate has open twice once in city and on highway now it doesn't shut at all its been like that for 5 months now and it started to not want to open or close the roof part as well it sound as if its jam.i worry about my safety and public as well. just paid over 2400.00 for rebuilding trany,power steering,and my gear shift as well it would not shift it snap off.transmission went out 6 hours before i got to my destination.it was towed to a trany shop around nov.12/2015 picked up feb.23/2016 hoping they would fix all the rest of defects it has. you name it this envoy has it or has had it from headlights bulb being replaced every so often and melting were light bulb goes, a/c and heater don't work properly driver side is hot and passenger cold or vice-versa. the passenger back sit i would not know.midwindow doesn't work it doesn't roll up or down or that latch that comes down to haul stuff as well it doesn't work. when i roll my power windows my headlight and engine idle powers goes down as if there is an electrical problem.i've invested on this envoy a week later when i drove it out of the yard. i have all my receipts from professional mechanics.its been a bad experience.i hope my trany doesn't go out after i'm done fix all this other problems. i read after someone had rebuild the trany 13 months later he had the same problem again with his envoy. it's not safe to operate a vehicle with so many issues especialy with no back lights going from good to not working.every time i have to be checking if i have my rear lights are working or in front and also my front low light i have no visibility what so ever.they are so dull.

Vehicle was being driven on a two way highway at approximately 55 mph. vehicle lost engine power while driving and the gas pedal lost resistance and went to the floor. vehicle was steered over to the side of the road. while the vehicle was steered over to the side of the road, check engine and other dash lights started flashing chaotically. white smoke started coming from under the hood. within a short time, white smoke turned into black smoke and then flames started to appears. the fire under the hood eventually continued to grow until it completely burned the engine compartment most of the first two rows of the interior before the firemen arrived and were able to put out the fire.

Nothing but this has been nothing but trouble since i bought for that dealership. guy from todd wenzel grand rapids michigan. i had just back into the shop several times they will not do anything about it she's just used to going ever since i bought this car and your is something wrong with the engine itself it cuts out car smells like something burning i do not feel safe in this car and i still owe on it i like to report todd wenzel buick to the better business bureau they're lousy people thank you also sent all this information gmc and have not got anywhere

The cruise control is intermittent. *tr

Parked the vehicle in a parking garage so i know the lights were working when we went in. as we were leaving approximately 3 hours later, the low beams would not come on at all. had to run high beams; had several people look at the fuses, replaced bulbs, etc. but they could not find the problem. a couple of weeks later just before i was taking it to a dealer to look at the problem the low beams began working again. approximately two months later the exact same thing happened only this time i heard a faint noise from the engine compartment and smelled a burning (seemed electrical) aroma for a few seconds when i realized the low-beam lights were not working again. after a week or so the lights came back on again. *tr

Stopped at street like, light went green started to move forward and car goes dead. no lights on dash, nothing showing, just stops abruptly. after a few moments tried restarting car and it came back on with check engine light. p0606 pcm failure code displayed. could have been rear ended by semi truck behind me or killed if i was trying to turn left at intersection. *tr

The speedometer and tachometer of the suv began to indicate incorrect readings. the speedometer works fine until we go on the highway and travel with the cruise control set between 65-70. then they will read the incorrect speed for a week or so then start working fine again. the tachometer needle just "hangs." i talked to 2 different repair shops who advised me that this is a common problem with envoy's and trailblazers. the cost to do this is over $500 or more. it appears that several other 2004 gmc envoy owners are experiencing this same problem. a recall should be in order. when i talked to the repair shops they said before they can correct the issue under my extended warranty is to see it happen. each time i had an appt set it would start working before the appt date so there is nothing they can do. very irritated that gmc doesn't address this now. *tr

Tl* the contact owns a 2004 gmc envoy. the contact stated that the speedometer failed to function. the vehicle was taken to a private mechanic where it was found that the instrument cluster needed to be replaced. the vehicle was not repaired. the manufacturer was contacted about the failure. the failure mileage was not available.

The instrument panel cluster on my gmc envoy 2004 is defective as it is on a multitude of other gm models between 2003 and 2005. one of the consequences is that the speedometer will not work or will report a faulty reading while operating the vehicle. this is an unsafe driving condition and for some reason gm has not yet issued a recall on this problem for gmc envoys of the year 2004 even though other years of this model and other models of gm vehicles have been recalled for this exact issue. please help gm do the right thing by it's envoy owners. we have certainly bailed them out enough. there is another potentially deadly consequence of this issue. if one were to be driving the vehicle at 60mph using cruise control and the speedometer were to all of a sudden peg itself to 20mph, there would be a sudden and abrupt acceleration as the computer in the car attempted to regain 60mph even though the vehicle was already at that speed. thank you for your time and attention to this dangerous speed control issue..

Vehicle is stuck in park, on the dash board it show the vehicle in reverse. instrument cluster is not working properly, tach gauge not reading correctly. temperature gauge does not work at all. forward air vents do not work all. *tr

I have been reading many of these post. i can't believe all of the things that have also happened to my envoy. i have had my back window blow out while driving, thank god that both of my kids that were in the back seat were not hurt, they were just scared and still ask if it will happen again. i also recently just had to have a piece on the gas line fixed which was almost $900.00 money that i didn't have and had to borrow. i am still paying it back. now as for last night my low beams are not working, i bought new bulbs and that didn't work, so it is back to the mechanic. oh and i have a check engine light that goes on and off. they really need to get on all of these things. it would be nice to have the car working the way it should be. i may just print these things up and bring to the gmc shop and see what the can do about it. i mean i really to love my suv but this is crazy. i am now kind of scared to have my kids in the car. *tr

While driving another motorist saw smoke coming from rear of vehicle and got vehicle stopped on side of road at which time the engine compartment was engulfed in flames. called fire dept and police. fire spread through the hearer box into the vehicle and across dash until it began burning the headliner. fire dept put out fire but was a total loss. there was no indication on instrument panel of any problems (all gauges showing normal readings). *tr

The "check gauges" light flashes followed by "low oil pressure" followed by "stop engine" and the engine stalls. each time this happens the ac has been on. sent to dealer and they were unable to reproduce this issue. has happened 3 times now. very scary. *tr

I have had an overwhelming smell of gasoline for weeks and my speedometer was only working intermittently. i took my car to an auto store and had them put it on the computer the code read small evap leak so i bought a new gas cap to attempt to resolve the issue. that didn't work so i took my car to the mechanic for it to be checked out as my check engine light came back on. on the first visit he scanned the computer and codes read po 442 & 445 ? small/large emission leak, he checked all components and could find nothing. i took my car back as the speedometer issue was getting worse and the gas smell was still present the same code came up for the emission/evap leak and still nothing for the speedometer issue. he then did a smoke test and found that there was a crack in the filler neck of the plastic gas tank that cannot be repaired and must be replaced. he replaced the speedometer sender which still did not fix the issue. after much research i have found both of these issues to be a serious problem with other envoy owners. i would like to know why there has not been a recall on these parts and why gmc is leaving the cost of repairs up to the owners. these are manufacture??s defects. this is supposed to be a reputable company. i have called into gmc support and they as well as staff at a gmc dealership stated that this was the same issue as was stated in a recall but my vin number wasn't included so no financial help was given. $1,215.29 later i have a new gas tank and my speedometer still does not work. this is ridiculous... take ownership for your product malfunctions!!! how many complaints does there need to be before a recall is issued on these vehicle issues? *tr

The speedometer begins to give faulty readings. at first it was reporting approximately 20 miles per hour under actual speed. this almost caused a crash due to excessive unknown speed. in the last few days the speedometer starts at 60 mph and is off by approximately the same amount so when traveling 50 mph the speedometer reads 110 mph. this is a massive safety issue and there are numerous reports about this yet no recalls. how many people must be injured or killed before you take action. *tr

Ac plug to fan motor burnt/melt, daylight/headlight connectors melted multiple times had them replaced 3 times each side... cluster/ radio/ac lights burning out lights out on different areas from illumination to gages to radio and ac control button lights head lights went out while driving so did cluster, radio and ac lights had the cluster replaced by dealer while under warranty back in 2013 over cluster shortening, had my radio replaced as well by dealer same time

Speedometer erratic. stays at 120mph at all speeds until vehicle is not driven. driven again, does not work at all or is erratic showing multiple speeds. as an example, freeway speed of approximately 70 speedometer will read 0 at times, 40 at times or even may read 120, very erratic. *tr

My speedometer stopped working. it used to either stay on 0 or go up to 90. i have been stopped several times for speeding because i can not determine my speed. since that broke, i have also lost all of my other instruments, including gas... i ran out of gas on route 495 in the middle lane going about 60 mpg!!! thankfully i did not panic and was able to get my flashers on and move into the slow lane and then to the break down lane. i have had many people tell me this is a recall on the gmc pick up trucks but not the envoy!!!! does someone need to get killed in order to have this corrected? *tr

Headlights stopped working, speedometer stopped working, fuel gauge stopped working, voltmeter gauge stopped working. *tr

Around august 2012, the speedometer and tachometer of the suv began to indicate incorrect readings. the speedometer goes weeks working fine, then will read the incorrect speed for months. the tachometer needle just "hangs." the vehicle was taken to an independent mechanic who stated that the dash cluster would need to be changed at a cost of at least $600, possibly more. the dashboard cluster was not changed. it appears that several other 2004 gmc envoy owners are experiencing this same problem. a recall should be in order. *tr

Lock completely out of back hatch wire acts as if it has a short which shuts the whole back down i am unable to use my rear wiper at all interfere with my steroe shutting of when u turn off envoy when it shouldn't have been locked completely out of the rear bottom and the glass hatch i do not use my hatch now because i don't want to be locked out again it has happen twice and this not under warranty have seen othe complaints online due to same issues has there been a recall on this i have only had this envoy for 4 months and to be honest i think it messes with the air i have duel air and the passenger side gets colder quicker than the driver and never seemed to do this untill the wires g started messing up in the rear. *tr

Dashboard and gauges kept malfunction speed odometer reading incorrect had to replace also rear door burned out very costs very high.

Fuel gauge varies wildly from empty to full . bad place to run out of gas on i, 95 in the fast lane. *tr

I have owned a gmc all my adult life. this envoy has been nothing but problems ....now the gauges seem to be all screwed up and after reading post from online..i will need to put more time and more money into this suv. nothing like driving late at night worried about what's happening now. i go from sitting at a red light and my car losing pressure and turning off, to now every time i get into it and leave my house i hear the door bell and all my panels symbols flash and shows no gas to no battery life.. i am not pleased and will never purchase a gm again..so sad. *tr

One day my sunroof worked and the next day it would not. it was stuck in the in the open position (not fully open, but when the front end raises an inch or so). i took it to a gm certified mechanic and they said i would need a whole new assembly and quoted me $2,100. the dealership and gm notified me that they would not help me with this defect at all. my car is in excellent condition with only 85,000 miles on it, but it is only worth $5,000 and i paid over $14,000 for it in 2009 when i bought it from a gm dealership. i cannot afford to lose $2,100 on this vehicle. and this is not the first issue that i have had. when i drove it home from the dealership the whole instrument panel failed. they fixed that. then a year later, when i was driving home with my new born, the entire car shut down while in motion going 45 miles per hour. the dealership said that it was a problem with the computer and the warranty would not cover it, but it would cover a restoration of the computer. then when i went to get my vehicle the refused to let me take it until i paid $200. my vehicle has shut down while driving since that and can barely maintain idling at traffic lights at times. now back to the sunroof, after not being able to afford to fix it the mechanic took out the sunroof and just set it in the frame so at least water would not get in when it rained. however, it is just sitting in there and can easily be lifted out and may even get blown out on the freeway. when exactly will this become a safety hazard? when my sunroof blows off on the freeway and causes a fatal car accident? or when my car completely shuts down on the middle of the freeway and my children and i get killed in a pile up? gm has been convicted of neglecting to recall vehicles with safety issues recently. clearly, gm refuses to protect its customers. please help protect consumers and do something about this.

Cluster want power up properly at start up. warning lights give false information. and now radio sometimes want play correctly. ac fan want work on all speeds also at times. i looked up recalls and there was one 03v096000 but it did not cover my year. you can get different displays giving bad information on every start up.

Engine stalls when you slow down and the air conditioner or widow defogger is on . i have also had power surging. i had to replace the map sensor twice and the bracket and it is still showing bad. i also replace the cam shaft position sensor and the thermostat. also the wiper on the rear will not spray any water or washer. *tr

Tl* the contact owns a 2004 gmc envoy. the contact stated that the fuel gauge would display an empty reading after refueling. in addition, all of the other gauges on the instrument panel failed. the vehicle was taken to a dealer and the dealer stated that the instrument panel needed to be replaced. the vehicle had not been repaired. the manufacturer was notified and they offered no assistance. the failure mileage was approximately 132,000.

The ignition began to stick -- could not turn the key all of the way to the off position. had to jiggle it several times before you could turn it so you could take the key out of the ignition. at the same time, you could not take the car out of the "park" position. the shifter would stick. none of these happened when the car was moving. only when parked. also, beginning jan. 1, 2014, the rear tail lights went out in the car. sears said there was something wrong with the wiring in the back. *tr

The speedometer and gas gauge in my 2004 envoy do not work. just like everyone else here the speedometer in mine sometimes reads over 100 mph when i might be doing 35mph. most of the time it just stays at 0 so i don't know how fast i'm going. the gas gauge just doesn't work at all. i can't afford the repair and from all the other complaints i've seen gm should fix it for free anyway. how many people have to complain before the ntsb will get behind the car owners? one person here said that gm actually won a lawsuit and was compensated for the faulty parts but did not do the recall on the envoys! *tr

I was on my way to work doing 40 mph when i looked down to check my speed and the speedometer stated that i was going 70 mph and it was going higher. i begin to slow down but the speedometer would not go any less than 70 mph, even when i parked my car at my job it was still reading 70 mph. *tr

One day all my gauges may work i might shut the suv off and start it again and no gauges will work (speed,oil pressure,battery,gas,odometer,tach) when one works they all work when one doesn't work none of them work and you never know when they will do what they do. *tr

This vehicle has and had major electrical issues since new. instrument cluster replaced at my expense at 75000 miles. now door locks intermittent. won't open or lock by remote. rear wiper goes out when door locks stop. rear door lock out also. can lock doors from inside and manually lock driver door but rear hatch will stay unlocked. this is a safety hazard especially at night at a mall or even in my driveway. someone could enter my vehicle and hurt someone in my family when locks are out. in my driveway they could get access to my garage door opener and enter my house. i shouldn't have to remove my garage door opener everytime i enter my home. i think this is a very serious security issue for my family. i'm retired and can't afford the repair. i've seen this all over the internet but no fix from gm. *tr

Tl* the contact owns a 2004 gmc envoy. the contact stated that the fuel gauge malfunctioned and as a result, it was providing an erroneous full reading when the fuel tank was actually empty. the contact also mentioned that the speedometer and temperature gauge failed. the vehicle was not taken to the dealer. the manufacturer was made aware of the failure who did not offer any assistance since the vehicle was not included in any recalls. the vehicle was not repaired. the failure mileage was 60,000 and the current mileage was 90,000. updated 09/11/12*lj the consumer stated the vehicle has ran out of gas several times due to the failure with the gas gauge. the engine check light illuminates for no apparent reason. the consumer has also received a ticket due to the odometer reading a false speed. updated 09/13/2012 *js

Tl* the contact owns a 2004 gmc envoy. the contact stated that the gauges on the instrument panel to include the fuel and the speedometer were not responding. the dealer diagnosed the failure and determined that the instrument cluster would need to be replaced. the vehicle was repaired. the manufacturer was notified. the failure mileage was 65,300 and the current mileage was 65,600. updated 07/12/11 *bf updated 3/22/12 *cn

Tl*the contact owns a 2004 gmc envoy. the contact stated while driving the speedometer displayed an increase in speed over 125 mph and when he stopped the vehicle the gauge would display 50 or 70 mph. he does not know the actual speed that he was traveling. the manufacturer stated the warranty had expired and they will not repair the vehicle. the vehicle was not repaired. the dealer was not contacted regarding the failure. the failure mileage was 124,000 and the current mileage was 127,400. updated 07/08/11*lj updated 07/15/11

The temp gauge does not read correctly when the engine is running in the correct temp range. the temp needle is either in the overheating position (red area) or totally past the max temp on the gauge, almost spinning like a compass. because of this false reading i pulled my vehicle over on the shoulder of the interstate, thinking the engine needed to cool down. this was during rush hour traffic, and could have caused an accident on the highway. a search on the internet shows others with the same problem. gmc refuses to replace or fix the gauge if vehicle mileage is over 70,000. gauges , oil,water temp, etc, are in vehicles to assist the driver with their driving and for safety reasons and should last a lot more than 6 years. pulling over on a highway should only be done for an emergency, not because of a false reading, and may in the future, if it has not already cause an accident. *tr

Speedometer begin sticking above zero when car was turned off. gradually, the speedo stuck higher and higher, until it remained pegged and ceased to function. soon after, all instruments in the panel successive failed - including fuel gauge, tachometer, oil pressure, and battery level... it appears to be at this point a complete failure of the instrument cluster. most worrisome, the speedometer and the fuel gauge read incorrectly at all times, if they read at all. *tr

This is a safety issue in terms of being able to read the instrumentation behind the steering wheel. it is also a fire hazard. *tr

Speedometer and tachometer stopped working properly. these gauges do not reflect the speed of the vehicle properly. i.e. i am traveling 25mph and the gauge reads 100mph. *tr

Faulty speedometer on gmc envoy 2004 slt. reads 0mph while in use or 10 mph below actual speed compared to gps. stopped working day after dealership installed new battery and 60k maintenance. *tr

The instrument panel cluster on my 2004 gmc envoy is defective. tachometer shows incorrect readings, gas gauge does not work, lights flicker and dim, half of the radio lighting is out. i've researched this and have found this complaint is quite common. it seems that eventually i can expect the whole instrument cluster to fail! *tr

2004 gmc envoy speedometer/instrument panel failure. the speedometer sticks and now has failed. this is a recurring issue with this vehicle that has had multiple law suits filed against the manufacturer in different states. why has it not been addressed? and even more importantly, why is my vehicle (which is known by gm to have this problem) not included in the settlement (the settlement in included other gmc, chevrolet and cadillac vehicles)? it is a huge safety issue that should have been made known to me by the manufacturer before it happened. on this site alone there are more than 52 complaints just for this vehicle. why is it not being addressed. thank you. *tr

Speedometer was kinda sticking/jumpy but now staying around 85 to 120. *tr
