Every time this truck is due for emissions, a service engine light appears. Cost me 1k one year, 12k, another yr, $800 the last time. Huh? I will never buy a gm product ever again. My family only drives gm!

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.

I purchased the vehicle march of 2014 from sunset motors in coeur d alene, id. The following day the car died and I took it back to the dealer where they told me the fuel pump needed replaced; which they replaced. I left the dealership after the repair was completed and filled my gas tank when I began to smell a strong odor of gas. I pulled away from the pump and looked under the vehicle to see gas leaking from what appeared to be the fuel tank. I took it back to the dealership and they said that the neck of the gas tank was cracked and they would repair it. I left with the vehicle after sunset motors stated the repair was done on the gas tank. The check engine light came on the following day. The code was reading p0455 large evap leak. I have tried replacing the gas cap as recommended by autozone where I took the vehicle to have the code read. The light continued to come on over the course of months. I recently took it to aamco after my vehicle started vibrating while in idle where they informed me that the crack in the neck of the fuel tank was still apparent and fuel tank needed replaced. After doing research I have found this is a common problem for this vehicle and gm had offered to extend the warranty when research into safety was done previously which was accepted and no recall was done. Gm has stated the warranty has expired. I feel that the leak in the neck of the fuel tank is a manufactures defect as there is no known reason for a crack to happen in the fuel tank. Like I said previously I have found numerous reports of this happening to others with the same vehicle. I feel that it is a safety concern and fear the possibilities of what could happen to my vehicle with myself and young children in the vehicle until I am able to afford to replace the fuel tank. I would appreciate this being looked in to and the safety around the defect.

Check engine light came on, took my truck to the mechanic to have it checked and testing showed codes of fuel evap leak. I had to get this fixed as I was due to get my registration renewed. Got the vehicle back went for emissions test and the"check engine light" popped up again just as emission test was being done!!!. I could not believe it! So not only did I incur cost of mechanic but the vehicle failed the emissions test. The tech at the emissions center said the codes showed "fuel evap leak" detected., while driving home from the emissions test I smelled a strong gas odor, pulled into my garage and looked under the vehicle and it was not leaking however my whole garage stunk of gas. My garage is attached to my house, let the dog out and the dog even sneezed!.... Being a weekend and my only way of transportation I drove the car as little as possible. Monday took the car back to the shop and the tech noticed the strong odor , later the technician called me to tell me that the lines to fuel tank and the fuel tank needed to be replaced as they were leaking but only when the vehicle was mobile!!!!!. He also told me that the vehicle was a fire hazard and I could not drive the vehicle. Now what! I had to get this fixed as I need the vehicle to get to work. The additional cost was $960 not to mention the extension I had to pay the dmv to extend my renewal registration. Had the vehicle back a week now, no more gas smell but lord and behold the "check engine light" just popped up again! This vehicle only has 103k and very well taken care of..the mechanic says the code is still reading "fuel evap leak" . Somebody please help.!!!!!!! It seems as tho I am not the only envoy owner with this problem!!!!!! I loved this vehicle but totally disgusted and disappointed in gmc.

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.

Tl* the contact owns a 2004 gmc envoy. The contact stated while driving approximately 30 MPH, the vehicle stalled without warning and the service engine light illuminated. The vehicle was not taken to a dealer. The manufacturer was not notified of the problem. The VIN was not available. The approximate failure mileage was 89,000.

My gmc envoy stalls out when I stop at traffic lights. I then have to put it in park to restart the vehicle. Although test meters/equipment have been used to find the cause for the unexplained stall is still unknown.this happens apx. Once every (2) months. When the engine stalls out the "check engine light" comes on and last month the " reduced engine power" light also came on and the envoy would only move at 3 to 4 MPH.

I have been having an intermittent issue with my speedometer not showing the correct speed for the past couple of years and has been getting worse for quite some time. It has now reached a point to where the speedometer does not work, oil pressure gauge does not work, engine light stays one and the tach only works once in a while. I actually know three people within the my place of employment that have the same vehicle ranging from a 2003 to a 2005 that have the exact same issues with their instrument panels. Of course, the dealership says that there is no recall related to this issue but they would be happy to replace the ip (almost $700) to see if that corrects the issue. I also know of a couple of different websites where you can send the panel off and they will replace all of the bulbs and motors for less $100. It is a shame that gm would charge over 7 times that amount for an issue that is this wide spread. I have driven gm model cars for over 20 years and the engines seem to be good but the interior issues are at a point that I am tired of dealing with them. I guess that it is time to look to take me business to a different car manufacturer and that is a shame.

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?

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.
