Rough idle while in park and while shifting to second gear. Engine light flashing, oil in spark plug wells, cylinder misfire on cylinder #4. Changed spark plugs & wires, this did not remedy the situation. I had the SUV for 1 month and the drive train went bad. Two months later, I got my truck back from the mechanic because parts needed to be certified by a gm engineer. I have had nothing but mechanical failures since 2010 when I bought the vehicle. Now I have at least five troubleshooting codes and now I'm being told that the cylinder head needs replaced. This shouldn't be happening and I know now that I will never buy another gmc product ever again.

Everything started april last year and its one thing after another since. First my engine started stalling, while driving. One incident, I lost half a tank of gas within a 15 minute ride, which I have a 17 gallon tank. Then while driving on an expressway, it suddenly dropped from 70 to 20 before I could get over two lanes to get out of the way of traffic. Ive cleaned the throttle body, ive cleaned the camshaft actuator, ive replaced the air filter, fuel filter, and the oil twice within a 8 month period, and yet it still continues to stall. Now I recently change the water pump to see if that would help, even though my car was not over heating, now its stalling even worse; I cant even make it through a drive through without having to start it twice. Second and even scarrier issue, I hit pot hole one day and before I could make 15 miles, I heard grinding. A cv joint had to be replaced, then two days after that the other cv joint broke off and broke my front axle disconnect assembly. Did I hit anybody? No thank god I was in the right hand lane and could get over without hitting anyone or causing injury to myself. Ive replaced both cv joints and the assembly now and even did the struts while I was at it, but have also been told I need control arms now. And still my car is stalling, grinding when I turn and I cant get the check engine light to clear long enough to get it inspected. My drivers side windshield works when it wants to and now the car is starting to vibrate unbelievably. Ive kept my oil changed, ive kept my filters changed, ive never taken this thing off road and have had it over 7 years and just in the last year I have dumped more money in this car than I have since ive owned it.

I drive a 2002 gmc envoy and for the last 2&1/2 years during the summer, I usually notice that the fan seems to run very frequently. After a few minutes it usually stops and I don't think about it again until we restart it. We've taken it to two different dealerships including the one we purchased it from and they tell us there is nothing wrong with the car-it's just hot outside and the engine needs to be cooled by the fan so it runs longer and louder. Today, I took it in because it would not quit running and my check engine light came on. They want $700 to fix the fan clutch which we've been trying to tell them wasn't operating correctly this whole time.

Below is copy of letter given to gm dealership following the engine failure at high speed: 10/05/2001 to : bob ross service department 2002 gmc envoy 3,240 miles problem: on sunday october 4th, my wife was driving on 675 to fairfield mall from our home at 6:10 pm in the evening. She had traveled about 8 miles and was going 65 MPH in the middle lane when the envoy suddenly lurched and then quickly slowed with total loss of engine power. The headlights (it was dark) were still on and the check ABS light came on as she coasted to the berm in moderate traffic. At that point the car would turn over (battery ok) with the key but would not fire. She called on-star and they said it would have to be towed and called dispatch (case 00244572). She also called me so that I could pick her up. When I got to the car, approximately 6:15, I turned over the engine and it fired. The check ABS lamp was still on. I waited for the tow truck and he followed me to the bob ross dealership. As I started to drive, the ABS lamp went out, but the check engine soon lamp came on and stayed on the entire drive to the dealership (about 8 miles) where it was parked at 6:50 pm sunday night. During the drive, it was obvious the transmission would not shift out of one of the lower range gears (not sure which one) and it appears the engine was running in ''limp home mode''. It would appear some computer glitch has occurred which is critical to the entire engine control program. I am very concerned in that this vehicle only has 3240 miles and the total and sudden loss of power in moderate traffic and darkness could have placed my wife in a precarious position as she tried to move to the berm with no power assist (steering or brakes) available. Please check the vehicle out carefully to determine the cause of this unacceptable failure. John perkins
