Problems with 2002 GMC Envoy ELECTRICAL SYSTEM

Driving at night and headlights on low beam and then they'll shut off.

My right window passenger side window would not go up so i took it to a shop. he took the piece where i control the window off and it had caught on fire. it was all melted & corroded i have pictures

I began to have issues with my headlights, low and high beams, flickering off and on at random for about 4 months until my brake lights started to do the exact same 7 months ago and now they have quit working all together! i have taken this suv to 4 different shops now, and nobody has been able to figure out why this is happening. the last mechanic who attempted to fix the issue, says he found an older recall on the original manufactured tag lights being malfunctioned to the point it causes issues with the front and back lights. the man shown me the information on this recall, seeing the part # is listed on there, i compared it to mine and a neighbor's 2002 envoy; which both of our envoys have these malfunctioned parts. gm has not contacted us back, and we're at a loss because it's a part needed from them directly. we have spoken to many envoy owners on a web forum, and there are hundreds maybe thousands of envoys out there with these same issues, causing accidents on the road way too often! it's dangerous, and nobody will help with this irritating issue!

1: passenger seat belt likes to suffocate my passengers until they release rhe seat belt and rebuckle. 2: both dim headlights went out, checked relays, fuses, and bulbs nothing has worked. then found out my 2 brake lights are out along with the dims and not sure what is causing this problem.

Air conditioning won't blow out vents,and sunroof won't close all the way

Driver's side door panel controls not working. includes power window, seat heater, power locks, etc. not a fuse issue?

Tl* the contact owns a 2002 gmc envoy. the contact stated that the vehicle was taken to an independent mechanic for the electrical system draining the battery. the contact had replaced the battery several times. the contact stated that an unknown gmc dealer was contacted but failed to diagnose the failure due to the diagnostic fees. the contact mentioned that the instrument panel possibly needed to be reprogrammed and was done by the previous owners. the failure mileage was 175,000.

While in motion only, a engine light accompanied by a reduced engine power engages making the vehicle unmanageable to response and cause the vehicle to stall.

Tl* the contact owns a 2002 gmc envoy. while driving 55 mph, the vehicle experienced a total loss of power and the instrument panel malfunctioned. the vehicle was not able to be restarted and had to be towed away to the dealer. the technician diagnosed that the main fuse needed to be replaced. the vehicle was repaired, but the failure recurred. the manufacturer was not made aware of the failure. the failure mileage was 248,000.

Headlights stay on, or flash randomly, making battery drain. *tr

Tl* the contact owns a 2002 gmc envoy. the contact stated that after shutting down the engine, a fire started near the fuse box. the vehicle was not diagnosed or repaired. the manufacturer was not made aware of the failure. the approximate failure mileage was 142,000.

A day after replacing the battery, while driving, the driver seat started readjusting and heating on its own so i turned on air conditioner to compensate since i had no idea what to do about the seat while driving. when i did, rear passengers said the rear vents started blowing heat, and a strange clicking noise was heard in the right rear panel, so i shut off the air, opened the windows and clicking and heat subsided. however, the drivers seat continued to readjust and heat throughout my trip and the right rear window had to be pushed up manually once stopped because the electric opener for that window was no longer working. *tr

There is a problem with the ignition in my 2002 gmc envoy when the vehicle is on the key comes out of the ignition and it is not suppose to. i noticed that gm has the problem online and found out the hard way that my vehicle has this problem but gm has not put the 2002 gmc envoy on that recall list at all and i have already talked to them about it and they deny it i have the evnoy that the recals are on. all i get is the run around by gm about the recalls and they want me to pay for their mistakes. the envoy has 4+ other recall items as well the gm company don't want to take responseability for what they let happen and they need to be held liable for what is going on with the vehicles they made. *tr

Over the years i owned this vehicle, i had it serviced numerous times for engine failure. the last and final time, the dealership (ewing automotive) could not find anything wrong. however, while traveling on the highway at 60 miles an hour with a full tank of gas, i lost all power steering control and the car stopped dead. this was extremely dangerous and led me to take a minimal amount in a sale, just to get rid of this dangerous car. it is very disappointing to learn that gm was fully aware of this deadly issue. *tr

We were again driving on interstate 5 at 60 mph when the engine just stopped. we were once again able to coast to the side of the road. this is the 2nd time our envoy just stopped running at 60 mph. again, the mechanics could not figure out why this happened. i happened one more time, but i do not have the date. so that makes three times our 2002 gmc envoy suddenly quit running while at a high speed on the freeway. we are concerned this is an ignition problem like with the other gm vehicles this has happened to. *tr

Submission from constituent re gmc executive letter reply in engine stalling/stopping while being driven on the freeway of california. *smd the consumer stated the vehicle stalled several times. also, the service engine soon light illuminated, due to a faulty ignition coil. the dealer also replaced the ignition switch, as the possible cause of the engine stalling. the consumer continued to experience stalling issues, as the dealer was unable to determine the cause. when the vehicle stalled, the abs and brake warning light illuminated. the dealer found the rear speed sensor connector broken and not sitting properly in the sensor. they repositioned the connector and secured it to the sensor. the consumer discovered a recall, which described the same symptoms he experienced. recall # 04v289000. *jb

We were driving on interstate 5 at 60 mph when the engine just quit. we were able to coast to the side of the freeway. had to have the envoy towed to our mechanic. they could not find anything wrong with it. we now believe it was an ignition problem like with the other gmc vehicles. *tr

Stop engine/low oil pressure display continually comes on and while driving, the vehicle hesitates and at times will stall. after replacing pcm, oil sending unit, throttle body assembly, cleaning the pcv valve and map sensor and multiple other parts, i was told that the dealership did not know what it was and stated that they could replace the cam shaft actuator (for a cost of approx. $885), but they could not guarantee that would resolve the problem. i have taken my vehicle back to the same dealership from 02/14/2011 until 11/07/12 and still unable to fix the problem. i've filed a complaint with gmc manufacturer, but still have not been able to resolve my issues. *tr

I purchased a 2002 gmc envoy new in 2002. early this year the starter quit working, i had it towed to the dealer, they told me the starter was bad and it would cost $625. i repaired cars for 30 years before i became handicapped, now i am unable to repair, when i did repair i put about 20 starters in for $39 for the starter and 1 hour labor. *tr

2002 gmc envoy slt. engine stalls at highway speeds. loss of power brakes and steering. engine will not restart for anywhere from 20 to 30 minutes. this is the 5th time that this has happened to me in the past 4 years. 4 times on the freeway and once on a surface road. this time i was with my wife and 11 month old daughter. i was not able to pull the car over to a safe location. i ended up in the left shoulder in next to the fast lane with only about a foot of space to my right where the cars were whizzing by. i cannot tell you the terror that i felt, as my daughter was in her child car seat on that side as the cars passed honking. this vehicle is very unsafe. i have read many internet postings and it appears that this problem occurs often with this make and model, yet whenever i take the vehicle to the dealership all i get is: no codes are displayed, we can't duplicate the problem, or they start throwing parts at it. so far i have replaced a fuel pump and a crank angle sensor, had the fuel injectors cleaned. the problem persists. i want to make sure that my description is clear. the engine temperature is normal, voltage is normal, outside temperature can be hot, warm or cold, it can be day or night. it has happened in all of these conditions. what is worse is that i cannot restart the engine for around 20-30 minutes, presumably there is some sort of reset on the computer ecm/pcm that occurs that grants me the right to now drive my vehicle again? this is unacceptable. my daughter, my wife or i could have been injured or even killed. i have never complained about this before except to the dealer but now that i have a baby, i am livid. i am a very experienced driver and have always been able to pull the vehicle to safety even without the power assisted brakes or steering. i very much worry about less experienced drivers such as my wife who is from a foreign country and has only been driving for two years. if she had been driving we ...

on the way home from galveston , tx after spending time at the beach . the window switches would no longer work . their was noise in the arm rest. *tr

I own a 2002 gmc envoy bought used and it has been a nightmare since i bought it thankfully i purchased an extended warranty. now they say the main fuse block has gone bad, how i couldn't guess, and they say it is not covered under the warranty. is this not an electrical hazard that should be covered before something drastic happens, i can't believe i'm the only one this has happened to considering everything that has gone wrong with this vehicle! *tr

After starting the car, a burning smell entered the cabin. noticed the volt gauge was only reading about 9 volts instead of the usual 14. took car in for check up, and found the alternator had failed. after removing alternator found that the pulley could not be turned as the unit had seized up. this also damaged the tensioner which had to be replaced along with the serpentine belt. the mechanic indicated that we were very close to having a fire. *tr

Mid june 2006, wife drove to work and stopped at a gas station to get gas. when she restarted the car, the instrument power panel did not work nor any of the instruments such as speedometer. she continued to her job and parked the car. when she left work and started the car, everything was working again. she took the car to a gmc dealer about the problem. they said they could not do anything because everything appears to be working. i have done a search about recalls and found that a recall nhtsa 03v096000 appears to affect me. i am told by gmc that my vin number does not apply to this recall. *nm

I have been complaining of multiple problems with my 2002 gmc envoy since i purchased it in 2002. the most serious of these is the fact that my engine seems to idle very high sometimes and my gauges quit working temporarily. on 7/25/2005 i lost all power to my vehicle while it was running. i lost power steering brakes, etc. and had to coast to safety. i was very lucky that i did not hit another vehicle or crash. had this happened on a busy highway or while my children were in the car it makes me sick to think of what may have happened.

Stoped by cop, unaware rt front light went out, got warning letter. socket burnt and smelled strongly of electrical burning. taking it to dealer on monday.

After numerous recalls on my 2002 envoy i was leaving for work and the vehicle would not start. the dash lit up, horn, radio, alarm all worked, but the vehicle would not start. i could move gear shift from p to n and it still would not start. i had to have the vehicle towed at my expense. i was told gmc roadside assistance doesnt apply if you have aaa. dealer said (according to the computer codes) that it might have been a faulty ingition switch. they replaced it but it happened again. now the dealer said there are no comupter codes this time so they have no idea what to do. it has been at the dealer 10 days now. every time the dealer turns the key it starts up with no problem. i have contacted gmc on a daily basis to find out what they plan on doing. i bought it new, and it only has 18,400 miles on it. i'm supposed to hear from gmc today on what they are going to do. this vehicle is not safe to drive. it has stalled on the highway about a year and after i restarted it, it would not shift out of a lower gear and the engine was very loud. i had to have the rotors machined at 12000 miles because the brakes were pulsing hard and the rotors were pitted. so much for buying a new vehicle that should be dependable! i'm making payments for a vehicle that i dont have! *ak

I have had multiple electrical and transmission problems with my 2002 gmc envoy. yesterday my family and i were driving on interstate 80, while on cruise control, the suv shut off. i barely was able to get to the side of the road. i almost hit a vehicle getting off the highway since i lost power steering. after 15 minutes of not starting, it finally started. i took the vehicle to the dealership and they couldnt find anything. i have written many letters and tried to convince gmc that this suv is not safe.

The gmc envoy's electronics fail. no dash instruments or radio controls. happens intermittently. occurs when driving. the engine races unexpectedly. this has happened 10 to 12 times. the slv-truck is currently at the dealer who is once again attempting to repair it.*jb

Transmission does not work properly. have had it repaired twice, but still vibrates, and fails to move vehicle forward at times, from a dead stop. is very dangerous at intersections where moving quickly is imperative. also wiring problems which operate various remote instruments (mirrors, seats, etc.) fear of fire. rear door latch was replaced - clicks "locked/unlocked" while driving. seats move on their own while driving. *nlm

2002 gmc envoy, if you turn the heater controllers full hot you get 200 degree water running through the dash. install a cd and the heat from the hot water plus laser in cd cause the disk to catch fire. this problem will probably happen in bravada and trail blazer also.
