I was in the highway tail lights weren't working in was headed to Idaho due to that im still in North Dakota also like a month ago I was pulled over in the city for no back lights it's happen 4 or 5 times two on a 15 hour road trip.tailgate has open twice once in city and on highway now it doesn't shut at all its been like that for 5 months now and it started to not want to open or close the roof part as well it sound as if its jam.I worry about my safety and public as well. Just paid over $2400 for rebuilding trany, power steering, and my gear shift as well it would not shift it snap off.transmission went out 6 hours before I got to my destination.it was towed to a trany shop around Nov.12/2015 picked up Feb.23/2016 hoping they would fix all the rest of defects it has. You name it this Envoy has it or has had it from headlights bulb being replaced every so often and melting were light bulb goes, A/C and heater don't work properly driver side is hot and passenger cold or vice-versa. The passenger back sit I would not know.midwindow doesn't work it doesn't roll up or down or that latch that comes down to haul stuff as well it doesn't work. When I roll my power windows my headlight and engine idle powers goes down as if there is an electrical problem.I've invested on this Envoy a week later when I drove it out of the yard. I have all my receipts from professional mechanics.its been a bad experience.I hope my trany doesn't go out after I'm done fix all this other problems. I read after someone had rebuild the trany 13 months later he had the same problem again with his Envoy. It's not safe to operate a vehicle with so many issues especialy with no back lights going from good to not working.every time I have to be checking if I have my rear lights are working or in front and also my front low light I have no visibility what so ever.they are so dull.

Engine stalls when you slow down and the air conditioner or widow defogger is on. I have also had power surging. I had to replace the map sensor twice and the bracket and it is still showing bad. I also replace the cam shaft position sensor and the thermostat. Also the wiper on the rear will not spray any water or washer.
