| I had just purchased my envoy a few days prior and was on my way to get gas. the fuel was low but the fuel light was not on. when i stopped at a red light, my envoy died. this happened at every stoplight until i put gas in it. this has happened multiple times since then. it happens anytime my vehicle is between 1/4 tank & empty. the fuel light is not on when this occurs. it almost seems as if there is not as much gas in it as the fuel gauge reads. it has only stopped one time while i was actually moving (as i was coming down a ramp to get on the interstate). it did not start back up immediately when i attempted to restart it that time, but took several tries before it started. it will literally die every time i stop until i put gas in it. there have also been a few times where i have slowed for a red light, then the light turned green so i went to accelerate and the vehicle either sputtered and felt like it was not getting gas, or died completely. luckily, most times i can put it in neutral & get it to start right back up without having to pull over. however, i feel that his is a serious safety issue for myself & the other motorists traveling behind me as i travel very busy roads on my way to and from work. i have learned to keep the fuel above 1/4 tank but the way this thing burns gas, it does get low from time to time before i get to the gas station. i don't know if it's a fuel system issue or if the gas gauge is incorrect but this needs to be recalled because it is definitely a hazard for myself and others. additionally, everytime i start my vehicle since it has gotten cold, it idles very high - like a loud high pitched whirring noise. it then goes very low and almost sputters. it does this several times before leveling off and sounding 'normal'. again, i don't know if this is a gas or engine issue but i feel like it is not getting gas. *tr | |||

| While driving my vehicle without any notice whatsoever it will just shut off right in the middle of traffic. this has happen on several occasions. after a few hours of sitting it will start up immediately. they have not been able to diagnose the problem. we have had the fuel canister, ignition switch and evap sensor all replaced it is doing the same thing. by the way i've had the engine replaced, the transmission replaced the leveling boots replaced and still making payments. there was a recall on the fuel sending unit and they told me because of the mileage they couldn't replace it, but they had evidence at 79000 miles that it was bad because i had it diagnose for that same problem. from the time i purchased this truck it has been nothing more than a nightmare. i pray somebody could get me some assistance on this truck. *tr | |||

| While traveling on the interstate this morning, the speed on my 2006 gmc envoy dropped suddenly and i had to pull to the side the road where the car completely stopped. i notified onstar, who performed a diagnostic test and indicated there was an issue with the fuel delivery system. the car would start up again, but only momentarily and the engine would die again. i had it towed to my home and am contemplating what to do at this point in terms of repair. there was another issue just over 2 months ago when the fuel gauge was not working and it ran out of gas. no indicator light ever came on. there was at least 15 gallons of gas in the vehicle today, as i had just filled it up a few days ago and had not traveled far. i have filled it up every weekend since the indicator light incident. about 2 years ago, i had to replace other parts related to the fuel..possibly called a fuel regulator?? which was mounted to the gas tank. this occurred at 37,000 miles. i was denied an inspection sticker because of an issue with emissions and had to replace that part as well. *tr | |||

| Dt*: the contact stated that the vehicle does not accelerate smoothly and makes a loud noise during the first 3 minutes of driving. the accelerator pedal must be depressed all the way to the floor for the vehicle to move, and then normal acceleration begins after driving 3 minutes. the vehicle was taken to the dealer on 05/02/06 who could not duplicate the problem. the dealer representative inspected the vehicle on 07/20/06 and determined that the clutch fan that cools the engine created the noise but could not determine the cause for the acceleration problem. the manufacturer was alerted on numerous occasions who finally identified that it is normal for the vehicle's acceleration to perform in the documented manner. updated 08/15/06. 8jb | |||
