GMC Envoy Denali XL Gas Gauge and Oil Pump Problems



  • acortezacortez Posts: 1
    I have read all the complaints and mine is similar. I have a 2006 envoy with low miles, my check engine light stays on, my gas gauge does not work cant tell you how many times i ran out of gas.. and gmc says there is a tbd on all this but will not cover the costs.. I do not have money to fix the problems that my lemon is causing so it just sits.

    hi acortez,
    sorry to say your not going to get much from GM on this. sarah seems to really care about the problems the millions of our GM cars are having, but has no power to make GM repair or recall stuff... i put my truck into dealership and told only fix is a new instrument cluster [$700.] !!! screw that ... i found a place online that will totally rebuild your cluster for $300. and they do it fast !! overnight your faulty set, and have it back in 2 days... its really too bad cuz i loved my envoy, but GM lost a longtime customer....
    good luck cortez...

    Hi, I have been in the same situation, to where I am trying to sue for my vehicle. I purchased an 06 GMC Envoy Denali cash in 05, using the money from the military that was given to me from my husbands death. I have had several problems out of my vehicle, resulting to even purchasing a new engine for $8 thousand + in the year of 07. my truck is currently down again, because i was told I needed a new engine again, how convenient is that is goes out after my 3yr warranty on the new engine. To make matters even worse the dealership I bought my vehicle from and who did all my oil changes and repairs including the engine is now closed. I called the local delearship and gave my VIN# to see exactly when my engine was replaced, and they didn't include that in my carfax report, they worded it totally different. No one has information on the dealership or knows where their files are, which leaves me in a tough situation. If any one has any help or leads as to what I should do please respond. I have contacted a lemon law attorney, but all they say is that they can get the fee reimbursed for the cost of the engine. Although it sounds good, it still doesn't add up to the 38thousand I paid for the car.
  • I ended putting coils in from strutmasters ,not to hard to do you can unplug the level sensors so you salvage the air compressors
  • It sounds like some have had similar problems. First off, I had to quit using the dealer as their prices were 3-4 times what others charge, and they typically did work not needed, or oversold. Now, first off, we love this vehicle and regardless of the poor service would buy GMC again. We have taken regular care of this vehicle, and did not have major problems until this year. First the ac went out on the way to Vegas. We did go to a dealer for that. $1700! Now this week my daughter was driving when suddenly the check oil light came on. She drove right home. I checked and could not find any oil! We had just changed the oil 2 months ago and regularly check. Also, the vehicle does not smoke, and no stains in the driveway. Our mechanic said the engine was blown. On taking the engine out, he found that the seals were blown, causing the oil to be blown out at speed. Now I know the warranty is out, but these huge expenses all at once are disconcerting, especially with how we have cared for this vehicle. Another reason to not use the dealer, is the ballpark of almost $6000 versus $3600. Anybody had this, and what did you do?
  • Read all other post in response to mine. Thia is why many are look into class action. The same thing happened to many of us and we had to replace engine. If your gas guage has not gone out yet it will and then maybe cluster electrical problems. Many of our died with less than 100k some not much over but you're just getting started with the cost. Hate to give bad news.
  • Ok I have read, and it looked like an attorney was contacted, and you wanted in, and I believe, Rachel and more. If so, I want in, and what do I do? :mad:

    I brought my 2006 Envoy used in 2009 with 42,000 miles on it. I have had all oil changes and took very good care of my vehicle. I was told that a diagnostic was $1040...and it would not go towards the repair. It would be just to know what happened or why my engine blew. I have been reading these posts and realize that the 6 weeks my car has been out of order, I have been on a wild goose chase. I dealt with one dealer who quoted me $6700 just for the engine. Claimed they could not find a used one because these engines are supposed to be 'bulletproof'. Labor would be another 2100. Found a dealership that would do the diagnostic, and they found out that my car had a valve spring that broke off into the 3rd cylinder. As if I know what or how that happened. To make a long story short, GM paysfor half the repair which means I need $4300 to fix my car. I owe $9000 on it still. With no engine the car is worth $3000 maybe. I feel like my engine had problems from the beginning, GM SHOULD COVER ALL THE COST. Why would they offer half unless they felt some responsibility? My car has 72,000 miles on it which means in the last 3 years I have put 30,000 miles on it and then the engine blew. I was on an expressway with my 2 babies 9months and 2years old when this engine blew. Scared is an understatement for the way I felt when this happened. I live in a city where GM is huge, many of my family members worked for them at one point or another. I cannot believe the way I have been treated by their dealerships with their outrageous prices and their customer service assistance. By the way my AC is also gone in the car, I'm scared to ask them to look at that...I 've heard that the Denali motors have had some problems and that I should surf the net for similar stories like mine and came across this site. If anyone knows of any legal action I would like to be apart of any cases...I have called a few myself and I am waiting to hear back..I don't have $4300 to put into a 2006 Gmc Envoy Denali...even with a new engine its still a 2006 and only worth blue book value....Please help....believe it or not this is the short version of my 6 week ordeal.
  • Have you started a lawsiut , I would be willing to go in the lawsuit so that GMC can pay for these lemons we bought. Have you gotten anyone else . contact me if interested.

  • Not yet I need a list of everyone that would like to add there names to
    the list for this Lawsuit. I have taken good care of my GMC Envoy and it should have not caused this is such a early stage. I had low miles! So please send me a list everyone who wants to join me in a lawsuit. It is time we fight back. I know we will win. I have proff of proper care for my GMC!
  • It is time we fight against the Lemon GMC has sold us. Who wants there names to add
    to a GMC Lawsuit?
  • hi tanya,
    i've spoken to a lawyer about doing a class action once before, but he wasnt ready to move so it lanquished... i'd be interested in adding my name to one if moving forward .. please advise .. thanks..
  • i'm in !! keep me posted please .. and thank you..
  • As I said, I am in. Not sure what info or format is needed, as to private emails etc. , but I am out $4000. The mechanic said he could tell we maintained as the engine looked new, except for blowing out all the oil, blowing the rods, etc. And this is after spending $1700 on the AC in June! Problem is, we love this vehicle, and except for these two issues, we would be ok. Just want them to at least share in the repairs
  • Hey, should we contact and promote this on facebook? Maybe find others with the same problem, and we can email or whatever.

    I'm in too. Please let me know if you have an atty for us to contact.
  • I have an 06 envoy and have had the stabilitrak sensor come on repeatedly, always shutting off after restarting the vehicle. I have had my mechanic look at it repeatedly but cannot find anything wrong, no codes come up and of course never comes on while he has it in his possession. It happens only in the winter or when it is wet out. It comes on within the first km of driving, and it frequently seems to be triggered when I make the hard turn around at the end of my cul de sac. I see there were many other people that commented on this problem but I haven't read any posts that explain what the issue was. I have not taken to the dealership yet. I have a mechanic that has not charged me for his time because be hasn't found the problem yet. Since this is NOT how dealerships operate I hesitate to take it in and spend hundreds of dollars for their time if they cannot find the issue either. Can anyone let me know what the issue with theirs was?
    I have also just had my fuel gauge stop working today. It fluctuates from empty to 3/4 full randomly. It started immediately after filling the tank today. Stayed on empty with light on for about 20 kms, now it is going up and down. I see that people have had repairs done with GM covering half. Is this in Canada as well or only in the US? I do not usually go to dealership but I will if they are covering half the cost. This is a used vehicle with 86,000 kms, purchased from a family member that maintained it well and never had any problems before. They did not receive any recall letters about the fuel gauge
  • Fantastic. I just bought a 2007 Envoy Denali with 90000 miles, and there is a serious "Ghost in the machine". Check engine light flashing, backfiring and smoke out the tailpipe, a gas gauge that, when it gets past half, you can actually watch the needle drop to empty. It is at GMC right now, they called and said theres nothing wrong with it, "We've cleared the codes for you!" Oh, gee, thanks, now there will be no history in the computer to prove long-standing problems. This sucks!
