    I'm ready also. I own a 2005 Envoy. I've had a gas guage repaired. Now, I'm suffering with the oil senosr issues. I've also had the issue with the fan clutch at about 40,000 miles!

    I also have the same problem as you julien61, with my 2005 Envoy XL. I have seen a lot of posts about just call your dealer and they will split the cost with you or it will cost $150 to replace. Called Todd Wenzel GMC and he said $450 just for the fuel sending unit. So I am all about recovering my costs.

    I am the original owner of a 2007 Envoy. I think the fuel guage went about 20 months and 50K miles ago. I currently have 145K on it and finally need to have the fuel gauge fixed since I need to pass emissions for a plate renewal. Can't get the check engine light off without fixing the fuel gauge. Maybe more is wrong there too. No help or feedback from the dealer other than pay me, pay me, pay me... Don't recall ever getting a letter about an offer for GM to pay half - not that a cowardly offer like that is sufficient to a major issue. But now even if I had such a letter I understand there were mileage limitations. The tire pressure light goes on and off whenever wet. Plus like others the front speakers work on occassion. Add me to the list of those having "fun".
  • my fuel gage recently stopped working , my master fuse blew the other day, the tire pressure lights go on and off whenever they want, after reading all these posts i am not looking forward to other things going wrong but it seems like they are unavoidable....great

    I'm sorry that the gauges are having some difficulties on your vehicle; have any of these issues been looked into as of yet?

  • I had 2006 GMC Envoy which is giving inaccurate gas level readings. This is known problem with GM SUVs from 2005 -2007. the NHTSA has gotten 668 complaints. GM agrees to pay 1/2 the fee to fix it. My half was $194. The dealer stated they will not paid 100% because it is not a safety issue. I told them -"Try running out of gas on the entry ramp to the George Washington Bridge and see how safe it is". GM should recall theese vehicles and fix them

    I'm glad to hear that you have gotten 50% of the repair costs covered. How is your vehicle running after the work was finished?

    I am also having the same problem, I have a 2007 gmc envoy xl and my gas gauge went out. I understand that gmc is doing a 50/50 split on getting this repaired is this correct is it possiblo? What can I do to get this repaired? I am a single mother on a budgeted income.
  • julien61julien61 Posts: 5
    Bring your vehicle to a GM dealership & they will honor the 50/50 split on the gas guage repair. It cost me about $191 for the gas guage repair. Hopefully, you won't experience the oil guage problem. :lemon:

    2006 Envoy
    Have had the same problems for 3 weeks with my Envoy. Took in to have part replaced today. I also had to pay 1/2 for the repairs and I am furious!! After reading numerous customer complaints for the same issue same vehicle I feel GM should be responsible for the total repair/replacement to my vehicle and I will be contacting GM directly with my complaint! If I do not get any results with GM I will be making my complaint known to ANY media organization that will listen as I feel we as consumers are truly being taken advantage of by General Motors!!!
  • 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.
