#15 of 51 TOTALLY DIGUSTED WITH THE GMC ENVOY XL by brumpf Mar 19, 2009 (9:46 am)
I have owned GM vehicles for over 30 years. I guess you would call me a loyal GM customer, However this GMC Envoy has ended 30 years of loyalty. I have a 2003 GMC Envoy XL and have never owned a car with as many recalls as they have had on the Envoy. The engineering flaws and just plain stupidity are too numerous to list here.   1. Fuel Leak due to rust (partially reimbursed by GM) 2. Trim falling off while driving (rear hatch upper trim; left mirror lower light and turn signal) Left Door Trim pulling away 3. Windshield Wipers and Sprayers turning on by themselves. $650.00 electrical repair. 4. Can't program remote mirrors to work properly. 5. GM dealer installed heated seats that lasted one season and the dealer went out of business.   This vehicle now has 38000 miles and I'm writing this to alert car buyers to think twice about purchasing this vehicle.

Sometimes when I turn the key to start all the lights and gauges come on but it will not start. I turn the key to off and then recycle it to start and the engine starts right up. Any ideas? Replies to this message: moavbilly (Jul 10, 2009 7:45 am)

Hello all, This is my first time posting and I have a weird problem. about 2 months ago my wife called from work and said her truck wouldn't start. It was totally dead and I couldn't even get the key to turn out of the unlock position. I jump started it and it ran fine until this morning. Same thing happened. I jumped it and had the battery and charging system checked at AutoZone. They said everything is ok. I don't want to leave her stranded, what should I do?

Replying to: tidester (Apr 06, 2009 8:12 pm) The key would move, but it wouldn't turn backwards so you could remove it. once I jump started it everything worked fine. Steve

Replying to: claybreakin (Apr 06, 2009 3:18 pm) I have had the same problem 3 times with my 2008 envoy. Go out to start the car and it's completely dead. Put the key in and in won't give it back until you apply a charge to the battery. All 3 times the dealer could not find anything wrong.The first time he said I didn't drive the car enough to fully charge the battery. This last time he said that there must be something in my neighbor hood that "wakes my computer up" at night and cause the battery to discharge. I really would like to find the cause of this problem.

Replying to: russ53 (May 20, 2009 5:00 pm) I am no electrical wizard but I can say our friends did this and it was the dealer installed security system which had a hot lead and would drain the system over time. If you have a dealer or after market security system or other device disconnect it and drive the car for a while or not and see if the problem goes away. One way is to pull the main CB for the system Most have one in line soemwher . If not find where it is powered and pull the connection or whatever it is and see what happens over a week! Good Luck Replies to this message: russ53 (May 20, 2009 5:28 pm)

Replying to: sjack (Dec 08, 2008 12:03 pm) Finally found out there is a barometric sensor in the fule tank. If vapor pressure is not detected it screws everything up. I guess so you will go to a dealer. screw that; Decided to work it a little and the first thing was the fuel cap as we were thinking an air leak somewhere and went with obviuos first, TADA new filler cap and no more problems. Bought a dealer repalcement cap and it was different from the first or the first had lost some pieces. either way GMC will not be looked at ever again! What a pain and truly not nice enough vehicle to go thru this again Ever. Replies to this message: courtmays (Sep 23, 2009 9:51 am)

Replying to: sjack (May 20, 2009 5:14 pm) It's factory stock with no extra add ons. The dealer put an amp meter on it overnight in their shop and could not find any large current draws. The largest recorded draw was 22 ma. Thanks for the thought
#24 of 51 A/C controls 1-4 don't work, 5 does by ljhayes May 21, 2009 (3:43 am)
Recently during the winter months in upstate new york, parts have started faulting. At first, the A/C control 1 and 2 would not work. However, 3,4, and 5 worked just fine. A few weeks ago, 3 and 4 also quit working. I am thinking this a condenser resistor, but im not positive. Anyone have any feedback?
