Received a "check engine" light while driving the vehicle. The fault code that came up was po128 ( insufficient ambient temperature - ect ) upon researching the problem I discovered that this is a common fault on this vehicle. It is generally caused by a "sticking" coolant thermostat. This condition also results in poor heating poor heating of the passenger compartment. If this is such a common problem with vehicle as I have found. Gm should issue a recall and correct the problem at no expense to the owner!

Seems that the fuel gauge reads empty even after I fill it up. It will chime, illuminate the low fuel light and read --- for range left till empty. This has been a known issue. After you drive and use about 5 gallons it will then go from f to e every few minutes and then the check engine light comes on with code p0463. This has been a known issue. Gm stated that they did send out at one time a offer to pay half of the associated cost if we chose to fix this and it was only available for a short time. I was deployed overseas at the time so I never got that mail and I would not have been able to do anything at that point in time anyway, however they could have allowed me to do it upon my return, nope!!! They said that there is nothing that can be done now, and it is viewed on a case by case basis. They told me to see their liaison at my local dealership, he will then call the gm rep. It has now been over a week and still no reply. When I called gm back on my own, it seems they closed my case but did not have a reason why it was closed and I was placed from one supervisor to another. I have repaired or replaced so many thing on this SUV in excess of 7k already its not funny.( power pedal relay, and module, self leveling suspension, AC control head, fan clutch motor, AC accumulator, entire fuse block, entire short block of engine and half the top end.)now the heat and AC system are giving me issues with the actuator door as well as the control box where no air comes thru the dash vents only the floor and gmc stated that is a known problem that has affected many but that there is no recall on that either. Of course now I am over the allotted mileage and warranty. Some of us live in rural areas where its not a quick trip to a local store but a 17 mile round trip just to get to a small store.

I purchased my envoy approx. 1 year ago. I have 105,000 miles on it currently. My speedometer would get stuck at 50 MPH but would seem to always end up fixing itself. Now it is pegged at 120 and has been that way for 2 months. # 5 on my AC/heat blower is not working. My engine light is on. My windshield wipers turn on every time I start my car. I can not turn them off , usually after about 30 wipes it will turn off. This is very frustrating to me. As I am researching these problems on the internet, hoping to find some sort of recall, I find many other envoy owners with the same problems!!!! I really feel that gmc should be responsible for this as many people are in this situation. I have to say with this many problems, it's the vehicle not the people and I think gmc needs to back their product and take care of these issues.

Gas gauge continuously fluctuates between empty and full even with a full tank, this also causes the engine light to come on. There has been numerous complaints from other owners with the same problem but a recall has yet to be issued. Called the dealer and they said they will cover half the cost. Why not the whole cost since this issue is so prevalent?

Tl* 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

Fuel gauge indicated nearly 1/4 tank and the car ran out of gas. From that time forward the fuel gauge would bounce back and forth from empty to full right after I filled completely up. It would start to work properly after about 40 miles or so. I was told by a mechanic that my running out of gas may have had an effect on the calibration of the level sensor since it was only doing it when it was completely full and then would work fine after awhile. The problem continued to get worse, it continued to bounce back and forth when the tank was full, but within a few weeks started to do the same thing once the tank got down to around 1/2 full. It continued to get worse and now continually stays on empty. My check engine light would also come on when the sensor was going crazy, and now that its always on e, the engine light is continually on. I have to completely fill my tank and set my trip odometer everytime I fill up so that I have some idea of how much gas I have, but it has still caused me to run out two additional times since the initial time I ran out and I realized there was a problem. I have taken it to a dealership and was quoted a huge amount of money to have it fixed, especially since I have recently found out this is a very common problem with the sensors on gm trucks from that time frame and gm issued a recall notice. My truck currently has just under 117,000 miles on it. I bought it used from a gm dealer in 2010, and have not received any recall notification.

The gas gauge on my 2005 gmc envoy slt has began reading incorrectly. The gauge reads empty even when the tank has fuel in it. After a day or so the tank reads normal, then it begins to fluxuate from correct to empty. Then the check engine light will begin coming on, and will go off again with no resetting.

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.
