My driver side power window / door regulator assembly cable frayed and the window would not move up or down until repaired. This happened to the driver side door window in August 2014. Now in March 2015, being 7 months later the same issue has happened to the front passenger side door window / door regulator assembly. I use this vehicle for less than 5000 miles a year, I feel this issue needs to be looked in to for the defect of faulty cabling / poor quality. This will be the second time that I will pay out of pocket for the same issue within a year.
February of 2014, gas gauge started to go haywire. After approximately 100 miles, needle of gas gauge goes to empty and low gas indicator light comes on. November of 2013, passenger air bag indicator light stays on. Does not matter if seat is empty or occupied. July 2011, right/front window regulator cable broke-replacement cost me $340. 00. At this time shop found that front differential case leaking. This was replaced at no charge. Have not owned a gm product in over 15 years, now I know why. Come on gm stand behind your products, no matter what year they were manufactured. You claim that your vehicles are on the road for years and years, really. . . Kind of hard to drive and trust a vehicle that does not function properly.
My gm provided replacement battery (replaced at 80,000 miles three and 1/2 years ago) failed with another dead cell. The warning signs were random: a "security" warning light on the dashboard, the window safety lock became inoperable, windows wouldn't sometimes open or close, alternator wouldn't charge and the radio was locked, etc. . My golden retriever/dog could have been choked by the electric window control as she stands on the armrest with her head out the half open window. Instead, we were very lucky in that the window opened all of the way instead and she didn't fall out. This window control is the toggle type, pre the safety ones. The original equipment battery also failed with a dead cell.

Almost dusk, high beams were on. Thought I saw a flicker. Got behind another car and saw that it was my lights. Looked to my panel and my voltage was swinging between 9 volts up to 18-19 volts. Turned all power draw off except my low beams. Needle kept swinging and lights kept flashing. Was 6 miles from home. I made it. There was a discharge to my system instead of continueing to charge. Took to dealer. Nothing found. 11-6-2012 it happened again. Has happened inbetween also. Very intermittant. Had batttery & alternator checked at least 3 times. Always good. After incidents, works fine until next time. Never happened in summer. Always when cooler weather. Now that it is December, afraid to drive after dark. There must a bullentin or recall??? too many complaints on this problem. Don't want to get rid of my car. Engine is good. Only 69,000 miles. Is dealer just acting dumb?.

Have had to have the alternator repaired three times. First time 65000 miles because of noise. Second time voltage regulator third time rear bearing. Had to have the onboard computer replace at 90000 miles vehicle shut down and would not restart. Towed.
I purchased my 2003 GMC Envoy xl in 2008 from a NY dealer with 60,000 miles on it, the car didn't register any accidents with carfax. The day after I purchased the car my battery went dead and I was stranded at 7am with my kids. The dealer paid for the tow and replaced the battery. A year later while driving to my sons basketball game at night, the headlights completely shut off. I pulled over and used my hazards, my son inspected the lights and could smell something was burning. . The driver side headlight wire was burnt badly. We replaced the light and the wiring. The next day not only did the lights shut off again while driving at night, but I couldn't put my window up! the driver side window panel did not work, but the other windows worked fine. I paid $400 to have the panel replaced. (now the seat adjustment panel is not working on the driver side) the battery has been replaced 3 times in 3 years! when ever I would use the window, or the heat vent, or the charger inlets in my car the headlights would flicker dim. My mechanic did a amps check while my phone was plugged in,car was running,radio on, and heater on and stated the amps were fine, until I hit the window button, then the amps went way down. Cost to replace alternator $350. 00, that was in 2010, so far in 2011 I have awoken 3 mornings in a row to a dead car. I sat in the car with car off, doors locked one night to see what goes on over night. . Well the alarm sensor button didnt stop blinking red, the seat adjustments kept moving every 4 mins, the rearview mirrors were moving non stop, and the horrible beeping sound inside the car was non stop! the radio dash didnt shut off either, it was piping hot after a half hour of sitting.
I have had my 05 GMC Envoy for several months now and have taken it to be repaired at least once a month! my issue is with the electrical system and the headlights and console "flashing" at night. I have taken it to the dealership twice and the first time they checked the battery, some cables and gave it back to me saying they could not find anything. The second time I took it back about a month later because the light were still flashing. The dealership had it for 2 days and told me it was my alternator. I did not believe them and did not get my alternator changed ($675. 00) and my car has been starting and running fine. My headlights still flicker, but there is nothing I can do about it. I have read several other complaints about this and most of them go through a new battery and alternator and it still does not fix the problem. This is something GMC needs to look into and fix because it is a huge safety hazard.
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.

I purchased a 2004 GMC Envoy xuv preowned in 2005 still under warranty. It began dimming the lights in the dash board and at the radio area, I took it in to GMC for service and was told that they didn't find anything wrong with my vehicle. On another occasion my car would get louder underneath the hood if I sat idling for a few minutes in a drive through for example, I took it in once again and was told that it was normal nothing was found to be wrong. Now my odometer works off and on as does my oil gauge. Now that my warranty is out I would have to foot the bill to a few problems that I have pointed out to the GMC dealer ship on more than one occasion. I have even gone as far as to ask if there were any recalls and was told no there were not. At one point my middle window fell down while I was driving I took it to GMC to find out the problem and was told it was the regulator, insurance did not cover this and the warranty had run out. Approximately 2-3 weeks later my back window would not go up or down therefore the tailgate would not open, back to GMC I went and was told it was the regulator once again, at this point I asked again about recalls and why both regulators would go bad within weeks of one another, I was told it was a coincidence. Just as recent as July 24 my power locks began locking and unlocking on there own even while I'm driving down the street. I had the battery checked and it all checked out fine. At this point I would not recommend GMC to anyone or buy another! help.
2005 GMC Envoy - since purchase, the headlights will dim when driving at night; seems to happen after first starting the vehicle. The battery gauge will drop down to under 11 volts when this occurs. The dealer has tightened the ground connections and replaced the alternator twice; after returning the vehicle to the dealer a third time, I was told that this is "normal". The vehicle is now out of warranty with 50k miles and the problem still exists.
Headlights, interior lights, all lights on vehicle flicker while driving on the highway. The vehicle does this when there is no apparent load on the electrical system (I. E. Blower, defroster, ac, power seats, windows etc. ) the lights become very dim and then bright again in the matter of a few seconds. This can be dangerous to vehicles in front of you and approaching as they believe they are getting "flashed" by your vehicle. It is very unnerving driving with this random occurrence.
I have 2004 Envoy have had problems with alternator. Started about 6 months after I bought the Envoy had I replaced 3 times then started having problems with back seat window on passenger side not rolling up. Then my girlfriend had a flat on side of road and could not get spare down I had to go out and cut the cable that holds it up. That is a unsafe thing to do on side of hwy should not take 45 min to get spare down. Headlights dim and brighten gets dim enough that makes hard to see.
(2005 Envoy) about 1 month ago I noticed that my headlights were dimming while driving at night . This happened sporadically. When the lights dim, the heat slows down as well. The interior lights occasionally dim when this happens, too. My husband and I thought it might be the battery and started to look at the battery gage, while one of us kept an eye on the lights. This problem has happened about 7 times over the last month. Last week it happened about every 2 minutes while driving down the road. Very scary, as I thought the truck was just going to shut down. I took the truck to my gm dealer and the mechanic said that there is nothing wrong with the truck. The battery, alternator and wires were fine. He stated that with new vehicles and everything that is run in them this is normal. Although he also stated that he has never seen this problem before. Their computer told them that nothing needed to be fixed. We have no aftermarket products in the vehicle and the only things running were the heat and radio.
We have had several problems from the rear windows in the rear of the vehicle. The regulators have broken allowing the window to fall down into the door. This usually happens a bad time such as in a storm. The dealer has replaced the regulator. The brake light has been replaced several times for failure to work properly. The dealer has replaced the circuit board twice. The four wheel drive switch would shut off after you tried to put it back into 2-wheel drive. The dealer replaced a faulty switch. Several times the engine would stall and the instrument panel would go crazy. Now, the car is sitting in my yard and will not start. When you turn the ignition, the instrument panel shows that there is 40 pounds of oil pressure and the mph is 90 and the car is not even running. The dic says that the brake system needs servicing.
When dealership changed oil, an oil pressure hose was found to be leaking oil from engine. Problem was repaired by the dealership. Vehicle has experienced several problems with the windshield wipers, deale has replaced the multifunction switch, rear wiper motor, front wiper terminal board and wiper module. Rear speakers have humming noises, speaker was shorting out, later consumer heard whistle noises in the rear speaker. When starting, there was a rattle noise, dealer found exhaust out of alignment. Creeking noise caused by faulty door pins and bushings, passenger side kick panel loose/falling off, dealer found right side panel loose. Alternator voltage drops with load below 35 amps, dealer replaced alternator, there was a squeak in the rear suspension, dealer found the e brake cable was chaffing on bushings, dealer repositioned e brake cable. Right front wheel bearing grinding, dealer replaced right front hub. Left front hub replaced due to growling, dealer found hub was worn.
