    Hi,

    For those of you with an auto-volume control on your radios (Bose or otherwise), is there a really GOOD way to tell if that is working properly?

    How does this work? Does it "listen" with some microphone somewhere to auto-adjust the volume based on wind noise? If so, where's this microphone?

    Or is it all based on the speed of the car... or something else?

    thanks!
    Scott.

    Is available only on 2WD models.

    The Auto volume feature does use a Micro-phone. Even better, volume is controlled a DSP(Digital signal processor) within the Bose AMP. It actually
    monitors external noise and adjusts volume as needed. You can test it by lowering your windows as you drive. this will increase the volume. It is not speed based.

    Traction control is only offered on the 2wd vehicles, because it's seen as counterproductive to 4wd/AWD autosensing systems. In an autosensing system, it uses the same sensors as the abs brakes to monitor wheel speed. Instead of easing the acceleration or applying brakes when it detects front to rear slippage, it transfers torque from the rear to the front on the triplets (rear wheel drive biased) or front to rear for the car based FWD systems.

    The only problem is if you don't have any sort of locker, there is no way to handle lateral skids on a typical 4WD unless it has a skid control system which applies the brakes to individual wheels.

    Are you sure it doesn't use sensors on the driveshafts? I'm pretty sure they use speed sensors on the driveshafts for the auto-4wd, and AWD systems except ones with traction control (that use the brakes to swap around power)

    Mcgyver75,
    The bass comes from the front door speakers. You're system is working normal.
  • tlaurotlauro Member Posts: 504
    Not sure if I'd spend the money on an XL verion that doesn't offer passenger seating in the rear but it does have some neat features.

    I wish the rear windows of the triplets opened as does the XUV and the current 4-Runners. At least if not both that and the side windows in the rear...as many mini vans and some SUV's do. That would reduce the helecopter effect and really help the flow of air.

    I also like the dual function tailgate.

    Just my thoughts.

    2002 Bravada TRANSFER CASE "CHATTER" (like wheels are falling off) dealer says a fix for the encoder motor is on its way for mid Oct. G.M. says take out the fuse. They did and it was worse, no one could explain it. I feel that damage is happening every time I turn.
  • robfrompittsburobfrompittsbu Member Posts: 8
    John, thanks! If you get the number please post. rob
  • gam2gam2 Member Posts: 316
    I got a loaner while I waited for my Bravada transfer case got fixed. If they don't, I'd call
    customer service and tell them you don't feel safe driving it.

    My lease is up on my 2001 Impala LS in 2 weeks so I went to the dealership and checked out some Trailblazers. In have always wanted a loaded Trailblazer LT but I didn't like the black moldings on the side and I didn't like the body-colored strip across the grill. But it looks like my prayers have been answered because for the 2003 model year, the LT's have body colored side moldings and the LS has the black side body molding. Now I can get my Trailblazer LT and not look at the side in disgust. Good Job GM.

    I have a 02 LS and I also like the body colored moldings. I thought there was some type of mistake when the LS had it and the LT & LTZ had black. I am glad I got my 2002 LS.

    p.s. we also have a 2000 Impala LS with only 7,000 miles and we love the car. We use the Impala for trips (31 mpg. hwy.) beats my 14 any day.

    It appears as if GMC really does plan ahead and attempt to do things right. GM cleverly and clearly marked each Envoy with an oversized badge, square on the grille, reading GMC, better known as: a General Mechanical Catastrophe.
  • stoney11stoney11 Member Posts: 10
    How did yours get fixed? The parts are not out yet.We do not feel safe in this vehicle. It's been broke since day one and it's getting worse.
    Did they tell you to take out the fuse? Woulnd't you think if the fuse were out and the car was only 2 wheel the chatter would not be there? Maybe it's not tranfer case, maybe it's something else. Is it normal for grinding when putting car in gear? Never happened before and it's much worse when cold.
  • linn1linn1 Member Posts: 1
    I love the Envoy and will purchase one in the next few days, I'm sure. One thing about the SUV that is a little troubling to me is wind noise when I test drive the vehicle. Does anyone see this as a nuisance problem with their Envoy - or am I just being picky? I drove an '02 (used with 6,000 miles) and it had a very obvious wind leak that far exceeded the normal wind sound in the other Envoys I've driven; it was around the passenger door, yet the weather stripping looked fine. Please let me know if you've experienced wind noise either on this site, or my e-mail (LLAsher@aol.com). Thanks! linn1
  • ylabylab Member Posts: 46
    Linn1 - I'm willing to bet that the roof rack cross members are located at a different position on the noisy Envoy than on the others your drove. I made the mistake of moving my front member when waxing my truck shortly after buying it and the increase in wind noise was astonishing. The front member should above or behind the rear door's back window. You might also want to make sure that they're facing the correct way! (Some have an arrow, but the 'loop' should be towards the FRONT of the vehicle).

    Hope this helps,

    The local GM rep has me talked into letting one of the local Chevrolet dealership's service department install the license plate housing seal/gasket. For those of you that had this component installed, did it eliminate the 'oil canning' sound that was being produced when the flexing of the license plate housing occurred? I saw one TrailBlazer that had the seal/gasket installed, and there was adhesive oozing out from around it on an extremely hot summer day this year. If the seal/gasket is installed properly, does the license plate housing area of the vehicle seem to look okay?

    I have an o2 Eevoy that is on its way to the dealer tomorrow for the third time regarding the wind noise. It nothing short of ridiculous. The noise from both sides is way excessive...(i've tried all of the tricks), Hopefully, a regional service rep. will get involved this time around...To my knowledge, there are no service bulletins about this. I should have waited for the Pilot......
  • gam2gam2 Member Posts: 316
    Stoney11: Olds replaced the Encoder Motor on mine
    in May (p/n88935687). Taking the 4WD fuse out didn't help. My vehicle was out of service 18 days waiting for the part. I refused to drive it and they gave me a loaner. Maybe they are telling you when they expect the part. The binding is hell on tires and the entire drivetrain.

    Re wind noise: My Bravada has wind noise in both front and rear doors. The dealer says the body shop needs to look at it. It's been in the shop so much I haven't taken it back. I consider it bad. I removed the roof racks so that isn't the problem. I also tried all the fixes suggested here to no avail.

  • mlauricellamlauricella Member Posts: 24
    Regarding the adhesive oozing out from under the gasket, it happens. I find myself cleaning off the rubber cement like glue about every two weeks. Other then that, it looks fine installed.

    Every single triplet on the dealers lot has the same problem.
  • tblazedtblazed Member Posts: 945
    I have the painted side moldings on my LS. Only problem I have seen with the body color painted side molding is the paint is very easily chipped. If someone opens a door and bumps it the molding paint chips off. For looks I like the painted but for durability the black is probably better. Unfortunately.

    The factory body side moldings on my White '86 IROC are made of solid white vinyl, not painted. Can't chip.

    After griping to Chevy Customer Assistance center for quite some time about not getting a new car after my 2002 TB EXT engine had to be replaced last year after only 2100 miles, Chevy has issued me a letter extending the warranty period on my new engine to 6 years or 60k miles. This is a no deductable extended warranty on the entire engine. Perhaps others who are being jerked around should also gripe loud and often. The Chevy customer assist number is 1-800-222-1020.

    Good luck

    This morning my 2002 Bravada, 14,000 miles, was dead, just a few clicking and gear sounds from the dash area-eventually, those sounds were gone too. The only previous indications that something might be wrong were 1) seemed like it turned over slower than usual once a couple of days ago, but it did start. I turned it off and tried again, and it started normally 2) a month or so ago I noticed that the clock was a couple hours off, but otherwise everything was fine. I reset the clock and it was fine until today (but it was off again by a few of hours this morning when the truck wouldn't start). Now I get nothing when I turn the key, no radio reception, but the radio and temp is still lit up, as are the dash lights. Chimes are working weakly. Does this sound like a simple bad battery or does anyone have any other thoughts? Thanks for your help.
  • tblazedtblazed Member Posts: 945
    Look at the Delco "eye" on top of the battery. It ought to be green if the battery is fully charged. If it's green (charged) then you might have an electrical problem. If it's black it is discharged, but still might work marginally. Then again that "eye" is only looking at one cell in the batt. Also remember something about poor connections with the batt cable to battery terminals and bolts. Some might be cross-threaded and/or loose.
  • golden_doggolden_dog Member Posts: 12
    Since the AWD in the Bravada is really an electronically control auto 4WD system, it would really be great to come up with an override for the transfer case. Any home engineers out there with suggestions on how to do this??
  • tblazer503tblazer503 Member Posts: 620
    yup sounds like a dead battery... just be aware that there are quite a few screws supporting the crossmember holding the battery down... three last I checked.. they really didn't want that battery going anywhere! hehe
  • ross1962ross1962 Member Posts: 229
    My Trailblazer has the wind noise problem, but it's no where near as bad as the extremely noisy, turn-up-the-radio squeak squeak squeak that my '93 S10 Blazer had from the tailgate mounted spare tire. All in all, it's a much nicer vehicle.
  • paisanpaisan Member Posts: 21,181
    There is someone who is working on a similar item for the subarus. Since the AT subie awd system is electronically controlled, they are working on a knob so that you can lock-in torque at a particular value. Same goes with the TOD system on the Trooper. I don't know of anyone who's done it yet but I'm sure it's a matter of time.

    Hi all,

    I noticed that the Avalanche (and my brother's Z71 pickup) has the same tranny as our Trailblazers, but it has a button that enables "tow/haul mode" which makes the shifts crisper and changes the shift points a bit.

    I wonder if this goes through the PCM or if there's a way to add a button directly to the tranny electronics to our Trailblazers to do the same thing?

    Anyone have a wiring diagram for the 4L60-E transmission?

  • xntrickxntrick Member Posts: 27
    Would someone mind posting a summary of the strategies that have been suggested to decrease wind noise? I am pleased with the Envoy and believe it to be quiet but wouldn't mind it being even more so. Thanks in advance.
  • tblazedtblazed Member Posts: 945
    From the description below as to the how and what controls these transmissions, no doubt that mode button is an input to the PCM and the PCM program is what controls the shifts.

    "ADAPTIVE SHIFT CONTROL
    The 4L60-E uses sophisticated electronics to modify shift patterns as conditions dictate. The Powertrain Control Module (PCM) monitors factors such as throttle position, vehicle speed, gear range, temperature and engine load. The PCM also measures changes in the operating condition of the vehicle, which occur naturally over time as components wear. Based on these measurements, shift timing and hydraulic line pressure are adapted to maintain optimum shift feel under different conditions - for example, during heavy hauling or trailering. This results in improved drivability and fuel economy. The PCM also allows the system to self-adjust for minor variations in each new unit, ensuring that every customer experiences consistent performance, and ensuring that the transmission will produce a constant high level of performance for the life of the car."

    Can those of you who have had GM repurchase your Envoy, Trailblazer or Bravada please advise how difficult the procedure turned out to be and what reason(s)/issue(s) caused them to agree to the buy back??

    Many thanks!

    I had an open case with GM for my problems. Their
    only response is we are only obligated to fix the car. They said they do not buy cars back (an obvious lie), and closed my case dissatisfied. I've filed a complaint with the Better Business Bureau (GM's arbitrator). I don't expect anything from them. I'm guessing GM will only listen to a lawyer. It's a rotten way to treat those of us with the lemons they produced. Unfortunately, the ONLY thing that matters to GM is $$$$$$. Good luck.

    When did you file the case with the BBB? Isn't there a time limit for them resolve the case? Did you have one issue or a bunch? What were they? Will you keep us informed as to the disposition of the matter?

    GM has given me the same "we will not by the truck back" routine when I asked them to "do the right thing" and take it back. Typical stonewalling. They referred me to the BBB program that they agree to abide by. I'm curious who has gone through this procedure and what's involved other than the written submission of a claim. I get the impression that the BBB is pretty fair and rules in accordance with applicable state law.

    In my state the lemon law determines that a vehicle meets the lemon requirements by having three attempts to correct a problem or having the vehicle unavailable to the owner for a cumulative period of 30 days or more within the first 18 months since the delivery date. I'm at the three plus attempts level now on several issues and up to 15 days out of service since delivery at the first of the year. I want to make sure that I have a tight case before moving forward; that's why I'm looking for info from those with experience in this area.

    Thanks,
    Bimmers
  • archdukerizzoarchdukerizzo Member Posts: 35
    Go get a lemon law lawyer.
    They're free (GM will have to pay their fees once they settle) and you only accept the settlement if it suits your needs.
    Go check out www.lemonlaw.com and see if there is a link to your state. This is where I went to get a lawyer. I had enough of GM, went there and spoke with a lawyer who accepted my case. It's really a shame when people are driven this far all over a car.
  • triumphbobktriumphbobk Member Posts: 25
    It sounds like GM is failing in the customer service business. We have a problem with the encoder motor in our Bravada. It's been replaced once, reprogrammed twice, and now the dealer says that GM is redesigning it and the fix won't be available until October. I trust the dealer is telling me the truth since I heard the same thing on this list last week.

    My question is this - what constitutes safety? The Olds customer service line tells me that as long as the dealer says that the truck is drivable, then they won't authorize a loaner vehicle. If the AWD system fails at the wrong time, couldn't that be unsafe if you lose control of the truck? I'm sensitive to this since my wife lost control of our first Bravada (2002) last November, totaling it. It wasn't wet, she wasn't going fast, she only tried to avoid a dead animal in the road and spun out across 4 lanes of traffic. When I drove this truck in the snow last year, it would skid to one side when I forced it into AWD by gunning the engine on snow. So I think that if the AWD system is not working 'correctly' then yes, it is unsafe to drive.

    The woman on the Olds help line told me that it was up to the dealer to tell GM whether the truck is unsafe to drive. The dealer's service department has told me that they don't know what the problem is but that GM is working on a fix. If the dealer's service dept doesn't know how to fix it without GM's help, how can they judge whether the truck is safe, or not? Doesn't make any sense to me.

    Just like Bimmers' response above, she referred me to the BBB. I asked to speak with someone at GM and she stated that they work through the dealer network. I guess they use the dealers as front men to take all of the heat. It's no wonder these service advisors have an attitude sometimes.

    Sorry for the rant, I'm just frustrated. I'm trying to be reasonable here - I don't want to drive the truck until it's fixed. I want them to give me a loaner - that's all. There's plenty of cars on the lot (I wonder why?). Short of the BBB route, and potentially the lemon law, is there any other recourse here?

    Thanks in advance,

    Bob

    Did your lawyer get GM to buy yours back?? If not then aren't you stuck with legal fees? Or is it still pending? My attorney estimates around $6k if litigation required. I'm not ready to take that kind of hit if I don't prevail. Am gonna check out the website and follwup with their lawyer contacts. Thanks. We need all the help we can get!
  • twinrottstwinrotts Member Posts: 161
    I am currently shopping TB's and need some advice from the resident experts.
    I am going after 02's and have a dealer who is willing to do some work in area searches.
    I need to know if anyone can predict the gas consumption impact of the 4.10 vs 3.42 diff.
    Also, is there real practical use for the locking diff if you do not go off road?
    Also: Is the regional and local advertising fees listed on dealer invoices a legitimate thing for a buyer to pay?
    These fees are not built into the Edmunds Invoice price so when you compare the dealer invoice to Edmunds, there is a 400-500 difference
    that equates to the sum of advertising fees
  • archdukerizzoarchdukerizzo Member Posts: 35
    My lemon law lawyer told me point blank that they don't take cases that they can't recover, and at NO time will there EVER be ANY cost to me, regardless of the outcome.
    My "case" is still pending, but I clearly fall in the stature of my states lemon law, so even if it does go to court, there wont be a problem.
  • stoney11stoney11 Member Posts: 10
    TRIUMPHBOBK: Tottaly agree!! We feel driving the truck is a matter of safety, our power steering cut out for a few minutes then returned, also it has to be taking its toll on tires and drive train. I agree we should have a loaner till its fixed. Oh now it's the end of Oct.!!!!!!!!!!
  • pepper50pepper50 Member Posts: 195
    For any of you Envoy owners who have ordered and installed your own splash guards, do they come with good instructions for a flunkie like me? Or am I biting off more than I can chew. Also any installation tips or warnings would be appreciated. Was any drilling required? Thanks.
  • pepper50pepper50 Member Posts: 195
    I have an Envoy, and can't answer your TB questions other than to say that with my 3.42 ratio 2WD Envoy I get about 21 mpg highway.

    As for your question about advertising fees, it depends on where you are getting your car. If you are in a metropolitan area and your dealer is a regional advertising co-op with several other dealers, then they will charge an advertising fee that pays for their TV/radio/print ads. In this case, the ad fee is listed on the factory invoice down near the bottom, and will say something like "co-op fee" or "ad fee". If, however, you are buying from a small hometown dealer who is not in a co-op, then an advertising fee is not acceptable. In a small-dealer circumstance, any advertising is a cost of doing business. Even in the first situation where a co-op fee is assessed, the fee should not be more than 1%. Any amount over that should raise a red flag. Now if your dealer does have a legit co-op fee, you might be able to bargain it down out of the dealer holdback, but most dealers don't like to give up any holdback if they can avoid it. Good luck!

    First of all, read the posts on this page and then determine for yourself if you really want to take a chance with this vehicle...If you are a betting person, would you bet on a 50-50 chance of getting something that may or may not meet expectations because if you read all the posts here at edmunds and at SUV.com, those will be approximately the odds you face. I for one am already experiencing engine performance and internal engine problems with only 1,900 miles. I am sure other things will start appearing soon, just a question of time.
    To answer your question, the MPG of these vehicles are over-rated on the window sticker. The higher gear ratio will make matters worse, about a 1 MPG less, depending on your driving aggressiveness on the road. The higher ratio will power you to a faster start when standing at a light. I have the 3.73 and I am getting poor mpg, 13/19 city/hway. City is real stop and go traffic stuff about 90% of it, 18 mile drive everyday including return trip. I do not think the MPG rating has been certified by the EPA yet, per the exception at the GM web site.
    Locking Diff is cheap insurance in the event you encounter tire slippage while pulling a trailer or just regular driving on wet and muddy situations or snow. The Lock Diff will transfer power to the other wheel in seconds and stabilize the delivery of power to your rear. I got it in mine since the cost was negligible compared to what it can do for you.
    As far as Ad cost, I paid $412 in Metro area...I could not negotiate it out of deal. The dealer sold the truck at inv cost plus $200 for the sales guy. The inv cost included the $412. Whether that was negotiable or not, they certainly were very firm in their position not to take it out. Anyhow, I got the $2,500 rebate plus $1,500 GM Card credit, I was satisfied with the numbers. If they only would fix my truck now so I can say I got a good deal then I would say it was worth it.
  • tbcreativetbcreative Member Posts: 357
    While I love the Envoy and Trailblazer, I'm frustrated that GM is ignoring those of us who take their trucks off-road. I need MORE ground clearance, not LESS. I was hoping to see some possible additions to their 2003 line-ups that would include a ZR-2 type version, but that doesn't seem to be important to GMC or Chevy. So, here's what I'll be buying instead:


    http://www.edmunds.com/reviews/roadtests/firstdrive/74756/article.html


    I'm not trolling, just venting. I've been a GM loyalist for as long as I can remember, but it looks like Toyota is about the only one catering to my needs now. I was all set to get a Trailblazer or Envoy when they came out, but it looks like I'm glad I waited, because this is going to be one great SUV!

  • tblazer503tblazer503 Member Posts: 620
    tell us more about your extended warranty? or actually, just me... 6/60k? is this powertrain, or engine only? I would definitely go for this and probably keep the vehicle a little longer... planned on selling it early '04 before my 3/36 runs out... all these engine problems are concerning me... thanks
  • tblazer503tblazer503 Member Posts: 620
    Looks very promising, but like the triplets... looks can be decieving... I think that '04 might be a good year to buy one... hehe.. Hopefully the price doesn't skyrocket with this rebuild... very impressive V6, but not so impressed with the v8... If it made even 260/325 I would be more inclined to get it as opposed to the 235/262 4.0...
