#34 of 192 I share the same issues with my 2006 Envoy Denali by mherron1

Nov 28, 2011 (9:09 pm)

I am also having most of the same issues with my 2006 Envoy Denali. I already had the fuel sensor issue and it has been replaced. Now it is happening with the oil pressure. The gauge is peaked at the highest pressure and the check engine light is on. Mechanic says it is a common issue with the car. It has always stuttered (or bucked) at a stop light or stop sign as a previous poster mentioned. I also had to replace the throttle body last december at my cost.
The load leveling system went out (which also causes the tire pump in the back not to work) so that got replaced (under warranty) but it now has a slow leak in it and will have to be replaced again. I really love this car, it's my second envoy. I bought GMC because of the quality. My husband also owns a 2007 GMC Envoy. But I am very disappointed in all the issues it has had. I also have a whirring noise when I press on the gas, that repair is a $350.00 repair. Our 2007 just had the same thing replaced at 45,000 miles. There are issues with this car get that are not related to how well you care for it and GM needs to do the right thing and help to take care of the issues. I am going to be looking for a new car in the next year (if this one holds up that long) and after driving GM cars all my life I am seriously considering changing.

Hi Sarah,
 
  I have not spoke to a Dealership nor customer Assistance. I was only told that they were not covering by the mechanic that fixed my truck. He is the one that recieved the phone call that I was denied. I was going to begin Legal proceedings on Friday.

I don’t have oil pump problems.
 
I have fuel sender unit problems. I have an xl denali, which I believe has fuel pump and sending unit combined. To pull the fuel tank and replace the fuel pump/sending unit will be around $1000 at dealer. A friend of mine says he will do it for around $700.
 
At present, when I fill the tank, the guage flips back and forth, and the lo-fuel light flips on when the guage hits empty, then a minute later, it flips to full, and the ‘checkengine’ light is on. When the tank hits 7/8 full, the checkengine light goes off, and the guage work fine. Then, when it hits halfful, the checkengine light goes back on. Don’t remember if the guage flips back and forth on the bottom half of the tank, but I think not.
 
Anyway, presume the flipping guage has a bad impact on something, like melting a computer somewhere in the denali, so I presume I need to replace the fuel pump/sending unit.
 
Last year the a/c pipe in the rear broke, and it cost me $700 to fix. Probably $2 for the repaired a/c tube, and $698 to pull the fuel tank. That was a year and half ago, so I can’t bitch to the dealer that fixed it.
 
I have not dealt with a GMC dealer. The company that did the a/c prev was a Pontiac dealer, now does used cars. Still has the Pontiac mechanics.
 
This time, am having a friend do it, who runs a repair shop in town.
 
I can look up the vin, but the large bitch I have is that the denali will have endless problems, a thou here and a thou there. we bought it used three years ago, because of the terrific ride, the air suspension, and over 3tons, rides like the livingroom couch. The mileage is around 14-15, driving easy. I have an enclosed haulmark trailer, and with 300hp, hauling a loaded trailer is not noticeable, except for leaning towards gas stations when driving by. Beautiful ride, with those adjustable seats, I can drive for several hours and not be cramped up, no headache, no ringing in my ears from engine/road noise.

TDOUG... I understand your frustrations. I too own a 2006 Envoy XL Denali with 63,000 miles. Reading your comments regarding your the problems you have been experiencing makes me think you were speaking on my behalf. This truck have cost me alot of money in the past year. First the gas gauge went bonkers..cost $440. The stabilitrack kept shutting off last winter...$1000...Less than a year later this problem has returned today. Last month I had to replace the rear shock airbags. They had a leak causing the rear suspension to drop....cost $1200. All of these repairs were made by a dealer. I'm going to mention the smaller problems. Do any one know if there a recall for the stabilitrack issues? I'm going to call the dealer on Monday. Hopefully there is a guarantee on their work that was done less than a year ago. I simply can not afford to keep paying for these repairs. I am considering a Honda Pilot.

#42 of 192 200 GMC Envoy XL Denali....Costly problems by mrs1781

Dec 11, 2011 (4:04 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.

Mrs1781,
 
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.
 
Regards,
Sarah
