I also have a 2006 GMC Envoy Denali (67,500 miles) with the exact same problems. I had to have my rear air suspension removed, if my car sat over night the rear of the car would be almost on the ground. I finally had to have the suspension replaced with traditional suspension. I am having to constantly check my oil to ensure it is has not burned all of it, headlights keep going out while DRIVING, and now the driver side lowbeam light is completely out causing me to have to drive with my highbeams on. The new one is the throttle position sensor, I get the check engine light coming on, then all of the sudden the stabilitrack light comes on along with another engine light and the car looses all power (I get codes P0121, P060e). I have a long commute to work every day and if im lucky, it eventually gets up to 65 mph hour after a few miles....that is if it doesn't shut off.
This is my 2nd Envoy, I had a 2002 Envoy SLE which did not have as many issues has this top model.
After reading all of these posts, I do not understand why there hasn't been some kind of customer service recall. On the brand model's top trim/package, these are not issues those of us who are loyal to the GMC brand should have to pay for on such a large scale.

Sometimes when I try to start my vehicle, I just hear a click when I turn the key in the ignition. It takes several tries before it starts. Then I won't have any problems for a while. I also have a problem with my odometer light not coming on most of the time. However it seems that whenever the odometer light comes on, I start having the problem all over. Does anyone know what the problem might be? Thanks for your response.

I had same problem and it was my starter. I had to get a new one and no problems starting since. I have also replaced rear air bags and gas gauge. I will never buy a GMC again.

I've had similar issues. It took weeks to replace the throttle body, my headlights will go out; now I realized that somehow the harness burned up. This week the car refused to start and now have to change the whole electrical system! I am not happy. I have always owned foreign cars, this is my first domestic vehicle and have spent more on this car for repairs in two years than my 94 Civic and 05 Altima combined. This is crazy. Are there any recalls we're not aware of? I'm very skeptical going GMC again.

what have u done to correct the problem
#178 of 179 rough idle; unning lean (P0300, P0171)
Jun 24, 2013 (1:17 pm)
So I got the P0300 and P0171 codes on my 2004 Envoy XUV 5.3L v8 130k.
P0300 - Engine Misfire Detected
P0171 - Fuel Trim System Lean Bank 1
I've read about 100+ posts on this site on what to do about the code, and I've compiled a lengthy list of things to check (if you want the list, PM me and I'll send it to you).
Here's what I've done:
- 3 years ago, about 100,000 miles, replaced the fuel filter
- oil changes every 5-7k
This past weekend (6/22):
- checked air hose from filter to throttle body, no cracks found
- replaced the spark plugs with AC Delco Irridiums (part 41-110 from Advanced Auto Parts); broke one wire along the way, replaced only that 1 wire
- cleaned throttle body (didn't remove it, but used a cloth first, then used throttle body cleaner spray)
- inspected MAF but no clue if it's malfunctioning (looked clean though, wires looked good)
- looked for an EGR valve, it doesn't sem to exist
Here's the weird thing on the plugs: In cylinders 1,3,5,7, all 4 of the plugs were black and slightly wet (probably gas). In cylinders 2,4,6,8, all 4 of the plugs were white and chalky.
Could this be an O2 sensor on the driver's side? It seems the misfire isn't as random since it appears to be isolated to cylinders 1,3,5,7...any opinions on what could be causing these misfires and likely resulting in the engine running too lean in bank 1?
P.S. - I can't figure out how to upload an image of the plugs (but they are as described in this post).
#179 of 179 2003 Envoy XL Reduced Engine Power Problem
Jul 02, 2013 (6:46 pm)
I have had a used 2003 Envoy XL for about a year and a half now. It was running great for the first year. Then all of a sudden I had problems. I was driving down the street and my cars "Reduced Engine Power" Light came on and my speed went down to 15 mph and every time I restarted it the light was on . My Used car company towed it and ended up replacing the Throttle Body and within a week to 2 weeks I ended up having the same problem and replaced the gas pedal. Now a couple of months later I am having a similar problem, but unlike the other times, this time I am able to turn it off and turn it back on again and it runs ok for a little bit. It is usually happening when my gas gauge is at 1/4 of a tank. My idle is running high when I first turn on the car as well. I have read numerous posts on numerous sites that other drives have this problem but have yet to figure out why, and have been involved in accidents because of it. Is there anyway I can get any help?
