    When I purchased my 06 Envoy the sales manager said that he had read that 08 would be the last year for the Envoy, but I can't find anything anywhere that says or backs that up. Has anyone heard anything about GM stopping the line? Of course everything is open to change now with gas prices and the Envoy isn't known for it's great gas mileage.
    Thanks for any input.

    That's the way I heard it too.

    How in the world did you get 75K miles on your Bravada's Michelin Cross-Terrain tires? Yes, they are a great tire and I plan to replace them in kind on my 2003 Bravada, but that is with just under 40K miles on them. I've had the dealer and another shop tell me the thread is at replacement level and I've measured it myself using Consumer Reports thread depth recommendation and they are telling the truth. So, before the snow falls, October here in Colorado, I'll be putting a new set of Michelin X-Terrains on my Bravada, but I'll still be under 40K miles.

    BTW, the latest consumer alert regarding tires over 6 years old (side-wall deterioration due to aging of the tire compounds) also would impact my tires if I keep them beyond this year. They were manufactured in August 2002.

    I got about 62K miles on a 2004 Envoy XL Michelin Cross Terrain tires. Just replaced at Sears a few weeks ago as they were on sale for $169 +installation+road hazard+etc. WalMart and Sam's were up over $200 each before add-ons and tax. The Cross Terrains were not all the way down to wear bars, 4/16 to 6/16 remaining IIRC. Still legal, but they were getting as low as I like to go on tires. I had not rotated them in probably 30K miles so they were just a little uneven. I seem to recall looking at them a year or so ago and it seem the tires have gone up at least $20-30 each since then. IMHO just another cost jump due to high oil prices.

    $200 per tire before the add-ons and taxes is outrageous! I purchased sports car performance tires in past years and have never paid more that $130 per tire. I think there is a lot more inflation in our economy than the Fed is paying attention to. Time to tighten up the Funds rate and discount rate at the Fed before we are paying $300 per tire.

    I also noticed that there aren't the constant tire sale ads in the local papers like there used to be a few years ago. Something has definitely changed in this market in the five years or so since I last bought tires for anything.

    Lots of oil goes into tires. And they weigh a bit, so shipping costs have gone up.

    "the price of oil, now at all-time highs, makes up 60% of the raw materials cost for a tire. Natural rubber, a commodity nearing 28-year price highs, makes up another 25%."

    As tire prices rise, drivers delay purchases (USA Today)

    The increase I saw at Walmart and Sams encouraged me to go ahead and pull the trigger on the sale price at Sears...before those go up as well. I had gotten more than enough miles from the first set and if I get 40-50K miles from the second set I will be at or over the replace the vehicle time and mileage. I think consumers that were already stretched before this last years run up in prices are really feeling the pain now and it will probably only get worse for the next year or two. I hate to predict past that since we are where I thought we would be maybe 4-5 years from now... This has been crazy and I don't see where it will end in the short term.

    I am wanting to change the plugs in my 04 Raineer. I have never changed any with the individual coil packs. Does anyone have any advise?
  • As to the front differential leaking, I too have the same problem, I took my 2003 Envoy 64,000 MI in March 5 2008 -- was told the seal is leakig and had it repaired, I thought. In july I again noticed oil on the garage floor. I took it back to the shop that replaced the seal and was told the same thing, it is a design flaw and hard to repair, and that even if I repaired it again it would probably still leak????? The first time it was $885.42 and my extended warranty covered all but the $50 deduct. I was also told that the warranty might not cover it again if it was replaced again so I have to have it checked every so often and add fluid if needed, HOW STUPID IS THAT???.
  • wlbrown9wlbrown9 Posts: 867
    I have not looked at the Rainer/Envoy/Trailblazer plugs and coil packs. I will look at them soon since it is about time to change the plugs on my wife's Envoy. If the coil packs are similiar to the ones on my '00 Trooper it is possible that one or more will be difficult to break loose from the plug. Trooper has a rubber tube covering the spring down from the coil to connet to the plug..tend to get stuck and difficult to remove. IF that happens do not try and force them off since they can tear and if that happens you might have to replace the complete coil pack. Take compressed air and blow down the center of the rubber tube and it will pop right off. I used one of those small 'compressor' you can get for $20-$30 for inflate your tires...worked real well using one of the pointed inflater tips that came with it. You could probably even use a manual pump but might need assistance to hold it in place.

    Do any of you know if GM has discontinued the Trailblazer, Envoy and Rainier. I heard that neither one would be produced after the '08 models but I haven;t been able to confirm this. Thanks
  • wlbrown9wlbrown9 Posts: 867
    I went to and looked under the incentives they list... None of these were showing up in the list of 2009 models but were there for the 2008's. Interesting that they were showing $6000 incentives on the 2008s. But that does not really confirm either way.

    Edit... I next went to, selected GMC, then went to Build Your Own.. chose 2009 and the Envoy does show up there. So, maybe they are still building them after all.

    Have a family member that weighs towards 400 pounds. Any SUV model or sedan that can take that weight on a constant basis?

  • in your message about trailer towing you mentioned that the air suspension worked great to keep the load level---I am getting conflicting answers about the auto air suspension on my 2005 rainier some GM people say to disengage the system when towing others say leave it alone these same conflicting answers are also coming from RV dealer service people---so who do I believe which mode should I tow my trailer in----any insight from you could be very helpful

  • hardhawkhardhawk Posts: 702

    I do not have the ability to turn the air suspension on or off in my Envoy. It is "on" all the time and usually I hear it come on every time I start the car. It has done that since new. I can turn on or off the aux. air pump outlet located in the passenger side rear panel in the cargo area. I cannot imagine why someone would not want it on when towing unless there was some fear it would overload the system. That has never happened to me. I would think that even if you could turn it off while towing that the back end would sag lower due to the extra weight of the trailer tounge. My Envoy has the extra duty towing package so I have always assumed that the air rear suspension was designed to work in towing situations. Mine is a 2002 that I bought new 7 years and 1 month ago and the air suspension has worked the entire time. We have towed with it during the summer since new. Our boat/trailer weighs 5000# and the Envoy tows it just fine. Does your owner's manual say anything about it? Do you have a switch that lets you turn the air suspension feature on and off? On mine the air suspension has air bladders instead of rear coil springs. I replaced the rear shocks last year but they are not connected to the air suspension bladders and are just plain old shock absorbers.
    Good luck and keep us posted!

  • I have only had my rainier for a month now and did not tow my trailer (4800#) with it yet because I wanted to be sure about the air suspension----the fellow from the help desk at buick customer service told me to disable the system by just pulling the fuse when I am towing----I think that I will judge for myself by towing with and without the suspension activated----I am going camping for the holiday so I will try it at that time and let you know what happened

  • "the fellow from the help desk at buick customer service told me to disable the system by just pulling the fuse when I am towing,"

    That sounds like the absolutely most absurd "customer service rep's" advice I've ever heard.

    If towing something caused an adverse response in the model you own, the manufacturer would have designed something a little more "sophisticated" than pulling a fuse.

    And I would sure get hold of the franchise owner and get, in writing, what he would suggest in the situation you describe.

    The air bladders can handle the rating of the hitch. I would not tow with the suspension system turned off because the back end will sag like crazy and the handling will probably stink. If you are concerned about overloading the system, check your trailer weight (fully loaded) as well as the load on the hitch. You should be able to do that at any public scale.

    Good luck.
  • thanks guys for all of the input---going on the popular opions of your answers and my hunch I will not disengage the air suspension when towing---my vehicle will not be overloaded (I had it scaled) so the system should handle it with no problem at all plus the fact that it towed fine to and from the the yard where the scale was located

    thanks again

    You are most welcome. I have gained a lot of insight in 7 years in this forum. I hope your Rainier serves you as well as our Envoy has us. We had a few first year minor glitches, but overall the Envoy has been a great vehicle. With our oldest son getting his learner's permit soon we plan on keeping the Envoy for a good long time. It will be a great vehicle for him to learn to drive in. If you ever have a question be sure to check the search feature here as you may find that it has already been answered by someone. I have done that many times.
  • We bought a 2005 Rainier and we are not able to turn on the reading, dome and mirror vanity lights except by using the instrument panel brightness knob. The vanity mirror lights have never come on. The dome and reading lights will come on when you open the doors and when you shut the engine off and pull out the key. I was wondering if there was an adjustment I was missing?
  • very simple to do so by 1) reading lights--push either lens to turn on then push lens again to turn off 2) dome lights--same as reading lights 3) the vanity lights come on automatically when the mirror is opened if not then the bulbs are burned out and will need replacing usually by the dealer or a person who knows their way around cars quite well
  • Thank you for your help, but I don't think you understand. I have pushed the lenses and when the lights are on with the door open or after the engine is shut off and the key is pulled I can turn them off and on. If I am driving or just stopped with the engine on or off none of the reading lights, dome lights or the mirror lights will come on. I am not sure if the vanity mirror lights are working because neither one has ever came on.
  • sorry I misunderstood you but I also have a 2005 rainier and my lights will come on at any time with the engine running or not---I can't even guess what is wrong so I would suggest that if you recently purchased the vehicle take it back to the dealer and ask them how the lights are supposed to work or try calling buick customer service at 800-762-2737 expect a wait and have your V.I.N. number ready (vehicle information number from your registration

    I tried

  • Thanks for your information. I'll try the dealer and see what I find out.
  • The issue is with the the load equalizing bars. procedure is: back up to the trailer , shut of the air bladder pump [use fuse] hook up trailer, set up the bars as you do with any vehicle [so many loose links] then re engage the air bladder pump. Remember the number of loose links for the next time of hook up and you will not have to go through this exercise again. The point of doing it this way is that the vehicle height sensor will try to compensate for the tongue weight and you will not know if the bars are distributing enough or too much weight to the front axle of the tow vehicle.
  • On the dash just below the main light switch there is a button called the dome override switch, it has a picture on it of a light with a diagonal slash on it , activate that and all will be well. It is used if you have the tail gate open, as when having a long load and you don't want the interior lights on.
  • thanks a lot your input is exactely what I needed to know---now I can have ease of mind when towing my trailer knowing I hooked it up correctly

    thanks again

  • My dome and reading lights come on after I shut off the engine and pull the key out of the ignition and also when I open the doors and then they shut off when they time out. The problem that I'm having is being able to turn the lights on or off when the vehicle is not running or when I'm driving down the road. I haven't been able to get the vanity lights to work at all, even when opening the cover. I have also tried the dome override button and all it does is turn the lights on and off when they are on, as I described at the first of my reply. The only other way I can get the lights to come on is using the panel dimmer knob, but the vanity lights have never come on.
