“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. …”

“Driving on the highway the vehicle suddenly read empty on the fuel gauge, then the panel said low oil pressure shut off engine. I ran out of gas on a busy highway passing lane almost causing a bad accident with my 5 year old in the back seat as I could not tell my fuel level. The fuel gauge would work sporadically over the next few days and the low oil pressure would go away and come back. When I had this checked out it was thought to be the oil sending unit so it was changed along with the fuel sending unit. …”

“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. …”

“On 12/23/13, while parked the vehicle died. When restarting, it was a little slow but did end up starting. On 12/24/13, I had the battery tested and it showed that the cca's just needed a good charge so I let the vehicle run for 45 minutes. A few hours later, the vehicle would not even turn over. On 12/25/13, removed the battery and reinstalled it. The vehicle started fine and ran well for a few days. On 1/1/14, vehicle stalled while driving. Ended up restarting but I had to give it gas to do so. On 1/2/14, I started the car to warm it up and it started fine. …”

“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). …”
