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"

Fuel gauge registers empty after filling tank. Light & sound sensors indicate low fuel level. Fuel must drain slowly into tank or gas pump shuts off. Electrical dash indicators do not work for a time after fueling so cannot set the trip indicator to gauge the mileage to a tank of gas. Fuel on occasion does not shut off at the gas pump when tank is full.

Headlights began to dim, then brighten repeatedly, as to appear to be "flashing" other drivers. Shortly after, the oil pressure gauge malfunctioned. After the oil pressure gauge, a few days later the battery gauge malfunctioned. A few weeks later, the gas gauge stopped working right. Now, the engine continuously jerks, like it is missing due to lack of fuel. Contacted GMC on 11-09-2012. No solution.

While driving on the highway noticed that the speedometer was pegged at over 120mph. When I stopped it was still pegged over 120 mph. I also had to have repairs to the gas gauge. I had just filled up and the low fuel light was on.

The contact owns a 2005 GMC Envoy. The contact stated that when driving at various speeds, the fuel level gauge would fluctuate abnormally and the contact was unaware of the exact level of gasoline in the vehicle. The contact also noticed that the check engine warning light was illuminated for some time. In addition, the speedometer also failed. The vehicle had not been inspected by a dealer or an independent mechanic. The manufacturer was contacted and advised the contact that they would cover fifty percent of the repair costs. The vehicle was not repaired. The failure mileage was approximately 119,224. The current mileage was unavailable. Updated 12/11/12

The gas gauge went crazy. I filled up my tank but the gas gauge is showing incorrect readings. It jumps left, and right at random times, and sometimes reports that the fuel tank is empty even though I know it's full.

As reported by many other GM customers my vehicle has experienced the same fuel gauge/sending unit failure. It began slowly with minor inaccuracies in fuel amount. Then it quickly and steadily got worse until the fuel gauge doesn't work at all. I understand that GM acknowledges the problem, but refuses to pay the full price. I believe the NHTSA should force them to fully repair their faulty equipment which renders the driver blind as to how much fuel they may have. This could be very dangerous.

I'm back! yes here we go again a repetitive issue w/GMC here it's July 20012 and yet no reply from GMC or dealership on my continual problems with all gauges located on instrument cluster. Sure reimbursed partially for charges replacing fuel sensor but notified to contact dealer where repair was completed but no return calls from GMC and the so what dealership which they call their establishment. This was only one of many problems. Gauges fluctuate speedometer, RPM, fuel, battery, water temp just say all the damn gauges suck. How does GMC guarantee today try are vehicles today if not satisfied bring them back bs why not take all these GMC Envoy from 2003-2008 back or better yet resolve our issues. Strongly I feel let's all unite & file a major law suit against GMC for hardship, false information, defective product sold, stress, anger maybe they will address our issues asap. Disabled vietnam vet who depends on Envoy for medical appointments. Today rarely drive my Envoy due to my personal fear running out of fuel or being in an accident. Please department of transportation & highway safety or safercar.gov address our issues with extreme urgency, would be appreciated, check my previous issues reported. Yeah, was planning purchasing new GMC truck in 2013 GMC blew this from occurring totally, thank you for your valuable time.

I received a letter from GMC approximately a year ago stating that there was a recall to the fuel gauge on my vehicle. I didn't think anything of it since I had not experienced the issue and the letter stated not to take it to the dealer unless you currently had the problem. As of a week ago the fuel gauge stopped working. I fueled up until the tank was full and the gauge reads as if the tank is empty and the low fuel light is on. In addition the speedometer has is having issues now as well. It sticks at highway speed and then just goes to zero and stays there. If it weren't for my gps I would have no clue what rate of speed I am traveling. I have contacted GMC customer service as well as the dealership and the repair for the fuel gauge will cost me $240 with GMC paying the other half. It seems to me that they were aware that there was an issue before I did so why am I now stuck with the repair bills" why was this not fixed before the vehicle was sold to me since I purchased it used from the dealership? something should be done about this.I should not be held accountable for GMC's errors! in addition there are recalls on the other GMC models for the cluster gauge that affects the speedometer. The Envoy was not included because there were not a sufficient number of complaints. Once again why should I be stuck holding the bag on faulty equipment? what can be done to get this resolved"

Repeat problems since car was purchased brand new at dealers. Air /O2 sensors defective/replaced. Defective fuel pump/fuel sensor/electronic gas gauge; flickering/dimming headlights; freezing/inability to control driver's side seat and controls. 1/4 of front instrument panel lights out; drivers side seat control lighting 1/4 out; check engine light and low fuel light on continuously since 1997. Tie rods both replaced as well as both front sway bars. Immediately following vehicle purchase, check engine light would continuously go off. I would call onstar at which point I was told to take car in for repair w/I 7-10 days (often told a problem w/powertrain or transmission). At dealers service dept, told over and over again after tons of worry, concern and time spent, that electrical system on this car tends to trip/trigger check engine light and they would just reset it so after awhile, I began to disregard the light as I was in the dealership almost weekly. Approx 2 yrs after purchase, filled up gas tank and fuel light showed "low fuel". went back up to full, dropped to 1/2 and back to empty. Went back to full after car was turned off and continued to do this. After about 2 weeks, constantly stays at empty. Called repair shop and was told approx $700-800 to drop tank and replace fuel sensor which I could not afford and began to track odometer and refill tank after 200 miles driven after fill up. Have been doing this for 5 years. Jan 29,2011, I go for emission test. Fail D/T low fuel and check engine light being on. Go to mechanic, approx $950 repair. Check engine light goes off...and back on next day. Read thousands of posts online and am finding many, many Envoy owners experiencing same problems as mine. These are safety issues and GM should issue a recall on entire fuel and electrical system. Please call for questions/clarification.

I have had a problem in the past with the fuel gauge reading empty continuously as I have read from many other complaints. Recently I experienced a problem with the oil pressure gauge. At first the check engine light appeared intermittently and then the oil pressure gauge dropped to zero, at which time the message in on the lcd reading said "stop engine" and "oil pressure low". I immediately went to my gas station and checked the oil, which was only down a 1/4 tank. My mechanic stopped the car and started it again and the oil pressure gauge reset itself but once I started to drive the car again, the oil pressure dropped. My mechanic believes it is another sensor problem like the fuel sensor but is not completely sure. I only started with this issue today but it is more worrisome to me than keeping track of how much gas should be in my tank. I am curious to know if others have started to experience this problem. I have had the car since it was brand new and have drive 79000 miles. I also had a major issue with the suspension system with I believe is common in this vehicle.

I was getting my tank filled with gas and the fuel gauge needle pegged out past full, then bounced down to empty. It did this three times then went back to full. Since then it has continued to bounce around. The only way we knew if we had enough gas was to fill it and use the trip meter. The fuel gauge has ceased to move at all since April 2011. The check engine light has been on continuously as well since the incident. I love the vehicle but it is a major pain to keep track of the fuel when 3 people in the household rely on it. I looked online to see if there was a recall, only to learn this is a common complaint and nothing is being done about it. I priced a new cluster and it was over $500. Needless to say we still have to keep track of the fuel with our trip meter. GM should step up to the plate and fix this issue. They had no problem taking a bailout. My family has been buying GM products for years, however, no one in my family will ever own another GM product if they can't do the right thing for their consumers, and do it now. Not 5 years from now!!
