While driving down the highway and or while coming to a stop the engine just shuts itself off without warning. Everything in the inside stays on, but you have to put the vehicle in park and re crank. This is an extreme safety hazard and needs to be looked into.

I am so sick of my 06 gmc envoy xl. I truly give up. I had the stabilitrak and reduced engine light come on my car for five months. I have replaced the steering wheel sensor, the throttle body, and had the relearn the idle thing done, to no avail. This makes my fourth time going to the dealer, because I thought they could fix it. I have always bought gm. If god blesses me with another opportunity to buy a car, it will not be a gm. It throws my car off. I've had to pull over and start the car over a thousand times....

I've seen many forums online about this problem, but there is no recall? I've even called gm. I still had to pay money. Resetting the computer has done absolutely nothing. Just wanted to rant, because besides giving me some of my money back (to the tune of a grand), what can I do?

Takata recall I have had to make many repairs on this vehicle. However, now the lifters in the engine collapsed. The vehicle only has about 87,000 miles on it. This is unacceptable. There have been many complaints about this vehicle and the lifters collapsing. We are a one income family and the repairs to this vehicle are astronomical. Well over 3500.00 Dollars. This vehicle is not drivable and has been sitting for a year now at my mechanics. The vehicle is of no use to me and has become a huge paper weight now....

The worst part is I still owe on the vehicle too. Gm needs to take responsibility and do a recall on this vehicle for the afm lifters, or pay for the repairs to this vehicle. I will never buy another gm product again. Own up to your mistakes and take accountability for this problem. I am not the only one this has happened to. Very disappointed in this vehicle that is suppose to be american made!!!!!!! Then you want to know why people are buying more foreign made cars. They seem to be more reliable than the gm products.

For more than a month my truck has cut off completely as I begin to break when I i am coming to a stop or when I am making a turn into a parking lot or at a corner. Sometimes it happens several times in a row during one trip. It always happens when I am in motion but once I turn on the hazard lights, put the car in park, turn off the ignition and restart it, it cranks right back up. I was told, based on my description that it could be a manufacturers defect in the turndown solenoid switch or sensor associated with...

the automatic transmission. This is a safety issue but I need my vehicle. This problem always occurs when I am on a city street. It has never happened on a highway/interstate when I am in perpetual motion.This is the only vehicle I have and I can't afford to leave it for more than a day at a shop, nor do I think I should shoulder all the responsibility for paying for repairs if it is a defect inherent in the vehicle. Please advise me as soon as possible if there is any recourse I can take against the manufacturer so I can have these needed repairs done immediately. I have already had the gear shift cable replaced about two months ago thinking that this was the problem. That was a $250 job with parts and labor.

Failure of the dod lifter, also known as the active fuel management system. While at speed on the freeway, the dod lifter on cylinder #7 failed causing a misfire on the cylinder which caused teh engine to shake violently. This is the 2nd failure of a dod lifter on my truck. In nov 2014, a dod lifter on cylinder #6 failed, causing a engine misfire and a violent shake. The cause of the failure was determined to be lack of oil pressurize the dod lifter. Upon deciding to rebuild the motor rather than...

replacing the motor, we decided to replace all internal components of the motor simply because the motor would need a full tear down anyway. The lifters, oil pressure solenoids of the dod lifters, rockers, rocker arms, springs and camshaft were all replaced thinking that we might as well rebuild the block with new components to save off any future issues. After 1 month in the gmc service center, the vehicle was back on the road in dec 2014. This repair was $5,900.00 In march 2016, yes 14 months later, a 2nd failure of a dod lifter occurred on cylinder #7. The vehicle exhibited the same issues as in nov 2014. This failure occurred on the rebuilt motor on new components installed in nov 2014. This repair will cost $2500 just to replace the 1 lifter. No other components. This leads me to believe that a the dod failure is more common and is a design flaw of the active fuel management system. This issue is more than a tsb issue, it should be a recall.

Gas sending unit/fuel pump lines rot out due to corrosion and spray gasoline all over the underside of vehicle. The vehicle might stall but often times it keeps running, all while spraying gasoline all over the place. This one does not even trip a check engine light while running in this condition. The only warning was the smell of gasoline- some people do not have a sense of smell, and this could have been very dangerous. This is a fire waiting to happen. This corrosion issue is known to gm, why is this not a...

safety recall? This let loose on my sister in-law while driving, it could have resulted in explosion or serious fire.

Some of these have shorted out and caused fires- combined with the leaky gas sending units, this is a serious safety hazard. Do not park this vehicle in a garage- a fire waiting to happen...Come on- make gm take care of these problems before someone gets killed. This truck was at a dealer for the fuel leak, they told her it needs a sender unit and a bunch of other things that have failed on this poorly built truck, which include wheel bearings, abs sensors. Steering wheel sensor (? Really) inop door locks, leaking fuel, water pump leaking, failing headlights- that work when they want, and a whole bunch of other repairs. This fuel and electrical issue(s) should be immediately recalled. This is affecting a lot of people who live in the northern states with snow and salt on the roadways.

the envoy is not part of that recall. Obviously my vehicle has the same problem as the recalled vehicles, why is it not part of the recall? The first ignition switch failed at 65-70 mph on the freeway. This is a very dangerous problem. Since the rest of the electronics are connected to the ignition I have no safety equipment such as air bags. If I would have been in an accident, it could have been fatal. *Tr

I was driving on the freeway at 65-70 mph. The engine lugged a little like it was running out of gas but the tank was half full. The engine resumed running at full speed. A few seconds later the engine shut off. I was able to coast long enough to pull off the freeway. But without power steering and brakes this was not an easy task. Once the car stopped I turned off the ignition and put the car in park. I tried to restart the car but nothing happened. I called a tow truck but the driver could not get the car to...

shift into neutral in order to put it on the car carrier because the shifter is tied to the electronics. Without power it does not work. He had to call for another tow truck to pull the vehicle in for service. The service technician tested and found low voltage from the ignition switch. He replaced the ignition switch. Diagnostics, part and labor $307. This is a very dangerous problem. If I was not able to move out of traffic I would have been a sitting duck in the middle if the freeway.
