#42 of 204 200 GMC Envoy XL Denali....Costly problems
Dec 11, 2011 (3:04 am)
I purchased my 2006 Envoy Denali XL in 2009 with 45,000 miles in March 2009. I now have 63,000 miles. Since my purchase I paid $420 to repair for issue #1 -Fuel Sensor: I couldn't tell what was my gas level. Of course I got caught with an empty gas tank and the car shut off in the middle of the street . Issue #2- Cost $1,100- Rear suspension air bags- At first the rear of the car would drop down when it was parked but it would pump back up after turning on the car. Then it started dropping down while I was driving. This would cause the car to hit bumps hard and the car would bounce. Issue #3- Cost over $1000- The throttle body went bad. This caused the stabilitrack to shut down which slows down the exceleration. This issue was a big inconvenience. Today my engine light came on and the stabilitrack shut down again as I was driving. This was problem was fixed less than a year ago. No way this should be the same problem. If so, I'm hoping the dealer will take responsibility and repair it at no cost to me. Theres no way lightening should strike twice. Another issue I am having is...When sitting still at a light with my foot on the brake the car has a hard bumping/ pulling feeling. It feels like I was rear ended. The dealer said it I needed a fuel injection cleaning. Which I have have at least 3x's along with using fuel injection cleaner occasionally, I'm still experiencing the same "bang in the back" feeling. I love my vehicle. However, these problems are too costly for me. I am seriously considering to trade it for a vehicle that is well known for having less issues such as a Honda Pilot.

I appreciate the lengths you have gone to in order to make these vehicle repairs that you detailed in your post. Am I correct in that all of these have been done at your servicing dealership? Have you been in contact with your dealership since your most recent post?
If you aren't doing so already, I would like to offer to set up a case for you through Customer Assistance. This will allow for us to investigate your situation and to interact with you and the dealership as we seek to get your current concern(s) resolved (I see that your Stabilitrak has shut down and that you are experiencing what you called a "bumping/pulling" feeling). If this interests you, please include the following information in an email to the address on my profile here: your name/user name and contact information (phone and address), the last 8 digits of your VIN and current mileage, the name of your involved dealership, and a description of the visits you've made to address your current concerns. I appreciate your willingness to continue working with us.

#44 of 204 2005 Envoy XUV SLT Problems!!!
Dec 28, 2011 (12:51 pm)
I just “stumbled” onto this Edmunds forum while researching the rear load leveling suspension problems I started having a few months ago.
This sounds like one of MANY chronic problems associated with GMC Envoys over several years and models (i.e., 2004, 2005, 2006, XL, XUV, Denali, etc.).
I have a 2005 Envoy XUV SLT that I bought new in July 2005. It now has approximately 79,000 miles. I’ve done all of the required maintenance and repairs through the GMC dealership. The fuel sensing unit had to be replaced a few years ago. Fortunately, it was when the vehicle was under full warranty so, I didn’t incur a repair cost. I’ve too have experienced “poor quality” issues posted by several others such as labels peeling off of knobs/buttons. I had to replace the rear gate window regulator after it went out on its own.
A few months ago, I noticed the vehicle’s rear periodically lowering after being parked. It would rise to the normal level shortly after being started so, I didn’t think anything of it. But I’ve noticed the rear lowering happening more frequently. Based on what I’m reading in these posts, my concern level has jumped considerably because it appears others have had the vehicle lower while driving! I have 22”rims on mine and there’s basically NO clearance betweens the tire sides and wheel wells when it’s in the lowered position so, this could be catastrophic!
I know the vehicle has an air compressor in the rear compartment area that can be used for inflating tires, balls, etc.
1. Does anyone know if this is tied into or related to the auto load leveling suspension system?
2. In addition to the air bags and a sensor, is there also a compressor that can go bad?
I’m also extremely disappointed with the “ton” of poor quality and design issues that simply should not be happening at such low mileage levels! Perhaps this is why they were discontinued!
Oh, I almost forgot…
My engine service light is now on and according to the OnStar diagnostics, it’s due to a defective heated oxygen sensor! I won’t even go into the really poor gas mileage I’m getting…!

I understand your concern in regards to your description of your vehicle "lowering". I don't have the technical information available myself, but if you were to send us an email with your VIN and your questions about the air compressor(s), we could ask our Technical Assistance Center. It is possible that they will recommend a visit to your servicing dealership for a diagnosis, as we prefer to not diagnose vehicle concerns over the internet.

It's nice to know I'm not the only one having a problem with their gas gauge jumping up and down. I travel to work at night and recently have been having problems with this. Imagine, 11pm cruising along, alone, and the needle shoots to empty and the light comes on and pure terror kicks in!!! A full tank of gas(so I think?) and it's telling me I'm empty, then it shoots up to half and back blah, blah, blah... NOW, I have to worry about being stranded in the middle of the road at night, in the middle of winter!! I love my 2005 GM Envoy, but this cost will put me ovet the edge!! Help!! Whom or what do I have to do, to get some resolve without having to sell a kidney. I see the NHTSA is investigating this, why are most GM owners in the dark, until it's too late?

One option available is to establish a Customer Assistance Case with us, where we could investigate your situation and explore the options available to you in addressing this concern. If this sounds like something you would like to pursue, please get in contact with us via email with more information, including: your name/username and contact information (phone and address, please), the last 8 digits of your VIN and current mileage on your Envoy, and the name of your preferred dealership.
I understand, especially after the holidays, that a visit to a dealership may not be an option. Our first step in the case will be to get your vehicle in for a diagnosis, which will involve a diagnostic fee, from which we can start to explore the options available.

I have had a similar problem with my 2006 GMC Envoy. Vehicle turns over for about 5 or 6 seconds after filling the tank and the fuel gauge jumps around for a while - then returns to normal after about an hour or so.
I called GMC and there is a special coverage which will pay 50% of the total costs for parts and labor. The special coverage number is #10054 (http://www.tbssowners.com/forums/showthread.php?t=67262). It will cover the fuel gauge/sensor if your vehicle is less than 10 years old and under 120k miles.
Call 1-800-462-8782. Follow the promptings to talk a person. Tell them about your problem and have your VIN# ready to go. They will put you on hold, find a local GM dealer, and set up an appointment to get the problem diagnosed. This is as far as I am now. I'm hoping the price isn't ridiculous...
Hope this helps.

Thanks for the response! Are these issues part of any recall that you are aware of. It looks like this stabilitrac issue is extremely common and difficult to resolve as well as expensive. The oil pump to seems to be plague many people with both Envoy and Envoy XL models. It seems like these were manufacturing flaws or possibly a batch of bad parts. It seems like if this is not a factory recall it should be made into one. This is the fourth GMC vehicle I have owned GMC Suburban, GMC Jimmy, and GMC pick up truck. None of them have ever given me problmes like this truck and I do not have the money to make these repairs at this time
