    Ross my boy, Visteon makes fords drive train, American axle makes most of GM's, I can be for certain that GM has both superior drive train and powertrain. When is the last time you heard of anything going wrong with a GM drive train other than a tranny.

    I have numerous friends with Explorers 2003's with 8000-17K they are saying the ride is getting very soft after 5K, its like driving a bus around the corner.

    Can't say that about my 2003 TB, solid.

    pilot? Way over priced jacked up caravan looking thing. Ugly.

    Murano? looks like a jacked up PT cruiser, can you tow with it? NO ROOM

    Highlander, looks nice, a little pricey, not bad, pretty solid vehicle.

    I too am out shopping and might be very close to buying. I've driven a Tahoe, Pilot, Envoy and Trailblazer XL.

    Tahoe: very nice but seemed too big. I have three little kids, but still the wife will drive it the most...power is very nice. V8 is quiet and doesn't work hard at all for city driving. Price is up there, but they appear to hold their value better. Discounts of about $3k.

    Pilot: nice size. Bigger than an Envoy/TrailBlazer but smaller than a tahoe. Very nice. Towing is good. 4500 and that includes passangers and cargo. so towing is about the same a the trailblazer. Nice third row seats, but little cargo room if they are used. 48 inches between the wheel wells. Quick steering that almost felt too quick for the size. Accleration is good even with less power/torque. Uses 0w-20 oil. Good luck finding that. Donut spare tire(I think) But Price !?! wow. 28K on up. About 31K for Pilot EX to match the trailbazer LS. MSRP take it or leave it. Add about $1000 for dealer installed towing. Better reliability? well maybe but the new Pilot has had recalls too. Not as many however. Possibly would be my choice if I won the lottery, but that price is getting close to a Tahoe...

    TrailBlazer/Envoy: nice. easy to drive. back seat is just barely wide enough for 3 kids in booster seats. Cargo area is about the same size as my Subaru Outback. That seems small for a 'bigger' SUV. Power is good. $30K but big discounts!

    Trailblazer XL: Long wheel base helps the stability and ride, but its noticably harder to turn. Third row doesn't fold flat, but its close. Second row of seats is not real comforatble and very 'bench' feeling. More cargo room than the short Trailblazer. Power is OK with the v6. Hey, I'm used to a mini-van. It will probably grunt a little towing the popup camper, but not too bad. Price about $33k (MSRP)or 29.8k (invoice)on LS model but big discounts again. (~$4500?)

    Biggest thing on Trailblazer is that it advertises 58 inch rear hip room, but the seat is only 53 inches wide.

    The Pilot is nice but I might save about $5k by going with the trailblazer. (LS model)

    Found this in the Aug 03 Techlink pg. 7. I edited.

    2003 TrailBlazers, Envoys and Bravadas with the 4.2L
    L6 engine, with the stabilizer shaft running through the frame.
    On earlier models, the stabilizer is mounted to the front of the frame.

    It appears some '03s with the 4.2 got changed.

    Anyway, that's something to look at if anyone plans to buy a suspension kit. The rear bar and bushings should fit fine but the front might be different.

    Rebates and discounts seem to vary in different regions of the country. In Ohio, some dealers have been selling Envoys at GM employee price to all, and the buyer also gets the rebates.

    The dealers tell me that their invoice price has 2% built in for 'Advertising'. Is this BS? Will I have to pay for it?

    2% is excessive for GM. An advertising fee should only apply if the dealer is in a regional advertising dealer group or co-op. A legitimate ad fee is itemized by the factory and will appear on the printout of the factory invoice. If the dealer himself has added his own "advertising fee" it is not legitimate; any local advertising an independent dealer does is just his cost of doing business. Ask to see the actual factory printout, and look down near the bottom. It may not say "advertising fee", but may have some other code words such as "dealer co-op advertising" or similar. The general rule of thumb is not to pay more than 1% for the legit advertising fee. The ad fee on my 2002 Envoy was $295. My dealer was in a co-op of North Texas GMC dealers that advertises on local TV and newspapers. The 2% that your dealer says he adds is excessive; I think GM ad fee is pretty standard at about 1%. I suspect your dealer is padding it with an extra 1%. I wouldn't pay more than 1% and ONLY if its shown as a legit fee on the factory invoice. In a metropolitan area where there are several dealers, the legit 1% ad fee is common. If your dealer is an independent one in a small town, any "ad fee" at all should raise your eyebrows. Keep in mind that the ad fee can be negotiable, but it might make the dealer less likely to negotiate other items, since both he and you are ultimately most interested in the total final cost.

    I think the comment about the Envoy vs Outback cargo capacity is a bit off.

    With all seats up:
    Outback: 34.3 cuft
    Envoy: 39.8 cuft
    EnvoyXL: 23.4 cuft (includes 3rd row being up)
    BMW X5: 16.1 cuft

    With all seats down:
    Outback: 69cuft
    Envoy: 80 cuft
    EnvoyXL: 107 cuft
    BMW X5: 54 cuft

    The problem with most midsized SUVs out there is they don't have much storage space. The only reason I drive an SUV is to transport large things or lots of gear. I don't do it because I like to spend more $$ on gas!!
  • jay_24jay_24 Member Posts: 536
    I took rough measurements. I took just the length(back of seat to tailgate measured at floor), the width (between wheel wells) and height (at rear hatch).

    I don't have the numbers, but from memory the Outback was longer by about 2", the trailblazer/Envoy was wider by 1" or so and taller by about 2". So they will fit a similar sized box.

    When I calculated cubic ft. is was about 35 for the trailblazer/Envoy and 33~34 for the Outback.

    Don't believe the GM numbers. measure your back seat is there 58" of room? The seat I measued was 53.5" on the Trailblazer and my Outback seat is 51.5".

    I was suprised too! However still interested in the TrailBlazer/Envoy. Brings back memories of the 91 Jimmy I had (182k miles when I sold it).

    Yeah, but the Outback tapers in at the back and sides, cutting off cargo volume.

    I'm coming up on my 36,000 mile warranty deadline for my 2002 TB and was wondering if anyone had input on items I should have the dealer look at or replace before my warranty expires. Any and all suggestions are appreciated!
  • 2002slt2002slt Member Posts: 228
    Just have them repair whatever is defective that the warranty covers. Remember, it's a warranty not a service contract.
    If you don't have any issues, welcome to the club.
  • jerrywimerjerrywimer Member Posts: 588
    There's an idea! A factory service contract with new cars for at least 3 years or 36k miles, whichever comes first. (I'd love that :) )
  • ficussficuss Member Posts: 541
    I would suggest going through the 12710 posts on this forum before yours and make a list of all the parts/ systems that have failed with the triplets (basically everything from bumper to bumper, with the exception of the original air in the tires) and insist that your dealer change all of them on your TB. Make sure you are running for the door when you demand this. If they do change all of the parts, your triplet will then be worth several hundred thousand dollars.
     But remember, they may say that if it's not broken they're not going to fix it.

    Anybody here have an EGR bugshield? I like the looks of them a lot and am interested in getting one. If anyone here has one, please post back and tell about the quality.

    Thanks,

  • tb4metb4me Member Posts: 41
    First--thanks to all once again who posted to this fan mess --the TB seems ok now with the used fan. It really is amazing how the GM engineers pulled this one out of a hat. A fan throwing codes--filled with fluid and a electrical switch, Believe me I'm takin the bad one apart for some inspection. For the post referring me to Auto Zone for a computer reset, that was a great post and I went right to them--however they don't do resets for service engine lights. However what all should know is that they will trouble shoot the computers for FREE! They also told me to disconnect the battery after the fix for 24 hours for a free PCM reset--it works just fine!

    For Steve--Host thanks for sticking with me--More bucks in my pocket now, but what lies in the future may be scary!

    For the TB fan--the fans comes off--left to loosen and right to tighten--with a bigggggggg wrench!, must remove the shroud and upper rad hose--the rest is pretty straight forward and reverse to put together. At about $100/hour for the dealer--it's worth the wrenching.

    Thanks again folks and have a great night!
  • aldan93aldan93 Member Posts: 202
    I love autozone, My autozone guy will reset the codes!!!! I have never gone there for my Trailblazer, just my wives Altima with 98K on it!!! They tell you what you need and play dumb, walk out the door and order the sensors on-line etc... some or Autozone's prices are very high. but ok for oil, clamps, can of 134A, wires, plugs, filters are ok also. Walmart is king for oil, and AC kits for re charging.

    Still have yet to change my own oil, thinking of switching to Mobil 1, need a good idea for ramps, and cleanup. Any suggestions?

    I take issue with Jay 24's statement that the Pilot's towing capacity is the same as a triplet. 4500 pounds for the Pilot is not the same as the 6000+ pounds for the standard triplets with the 4.2 engine. My Envoy pulls our 5000+ pound boat/trailer very nicely. I wouldn't try it with a Pilot (or an MDX for that matter). Another Pilot defect for towing purposes is the lack of a body on frame design. Essentially the Pilot & MDX are Honda minivans with different styling. They have many fine qualities, but towning capacity and ability are not among them.
  • jay_24jay_24 Member Posts: 536
    I'm just saying they are close.
    6200 - minus 800 for people/cargo = 5400
    5400 vs 4500 isn't much for most people. In your case yes the trailblazer with a frame is better than a unibody honda. For people like me towing a 2100lb popup camper there isn't going to be much of a difference.
    For the EXT trailbalzer default towing is 5800lbs? minus of people and cargo and its closer yet to the Pilot. Add the v8 and different gear and the EXT tows a lot more... Just proves you can make numbers do anything you want.

    Last night we looked at a EXT trailblazer. It doesn't fit three booster/car seats across the second row of seats. :( Might have to go up to the Tahoe or wait until kids are bigger.... The rear facing child seat is the worst one....

    Jay, to compare apple to apple you need to take out 800 lb (People and Luggage Wt. as mentioned by you) from Pilot's 4500 lb towing capacity.
  • quickdtooquickdtoo Member Posts: 266
    FYI from American Honda website:
    "Towing requires installation of power steering fluid- and automatic tranmission fluid-cooler, both available exclusively from your Honda dealer. Premium unleaded fuel increases engine torque and is recommended when towing above 3500 lbs. Maximum towing capacity is 4500 lbs. for boat trailers and 3500 lbs. for all other trailers. Premium unleaded fuel is recommended when towing above 3500 lbs. Refer to the Owner's Manual for additional towing information."

    Looks like 3500lb max if you don't tow a boat. tim

    A 2-3 ton floor jack from Sears, a regular screw driver for the access panel, 15mm socket on a 3/8 drive for the pan bolt and an 8 quart mininmum plastic oil collector works real fine. The oil filter can be had fairly easily with the wrench--there are a couple of ways to get to it too. Be careful though if the oil is hot it will run down your arm. The mess from the filter isn't that bad but will definately leave some oill below the filter--an old rag works well. For oil--u called it--Walmart! 5-30 is readily available and cheap! Fram filter 3675 comes in 3 flavors for u to choose from. I've been using the Castrol synthetic blend in the 5-30 weight. Its $14.05 for a 6 pack and $2.39 for the other quart. Filter is about 3 bucks. Good luck!!
  • jay_24jay_24 Member Posts: 536
    I've heard honda's towing is based on having passangers and cargo where most other companies don't do that. But maybe it does need to be subracted....just going on what I've heard.

    The towing the boat this is funny. What difference is there? somebody on the Pilot discussion said its because a boat is more aerodynamic... sure... whatever. Honda has been quieter about that 4500 vs 3500 thing... Maybe I can put a floatation device on my camper so I can have more towing capacity with the Honda?

    enough on this lets move on....

    Premium fuel increases torque--what ever happened to cubic inches?

    "Ross my boy, Visteon makes fords drive train, American axle makes most of GM's, I can be for certain that GM has both superior drive train and powertrain."

    I think you got the idea I was saying the Fords are better. I was just saying I didn't know. I've always owned GM's. Over the years, the GM vehicles seemed to last longer due to superior engines and trannys. And I was once advised to by AAMCO mechanic that if I wanted to spend a lot of time in transmission shops reading old magazines to by an "Exploder".
  • hardhawkhardhawk Member Posts: 702
    There really is a difference between towing a v-hull boat and a camper or cargo trailer. The front facing part of the latter two is flat and blunt, creating far more wind resistance than the v shaped hull of a boat, which splits the air flow just like it parts the water when in the lake. One of the old 70's vintage tri-hull boats would be a far different matter. Jay is right, we have beat the towing issue to death, so I'll certainly move on. BY the way, if you want to use the three car seats across one row, you really do need to move up to the full size sport utes, as they are virtually all considerably wider than the triplets. This affects towing issues as well, the prime example being the need (or lack of need) for extension mirrors on both doors of the tow vehicle. You really need then on the triplets if towing a high camper, cargo trailer, or boat.

    The Honda probably wants premium when towing to prevent detonation under load. I doubt it helps the torque curve.

    I do not need a jack to change the oil on my Envoy. I weigh 190 lbs though so those with a bigger waistline may need more room. I unbolt the whole plastic panel (not just the access panel) to drain the oil. Takes 2 minutes and makes the job easier.

    Preventing detonation is directly related to the torque curve. Premium could help. It would allow more timing advance without knocking, increasing low end torque. With lower octane, it would detect knocking and then back off the timing.

    This is only true if the vehicle is designed this way. Honda tends to design for premium and then just back off timing if regular gas is used.
  • pepper50pepper50 Member Posts: 195
    My dealer service guy told me today that when I bring my Envoy in next time at 15,000 miles they routinely change the air filter, rotate and balance the tires, do an oil change, brake check, and some other items for a total of $139.00. Sounds kinda high to me. I asked him do they change the air filter even if the indicator gauge has plenty of life left in it, and he said "yes" that it was recommended to change it every 15,000 miles. Then why do they even bother to put the indicator gauge on there? How many miles have some of you gone by using that indicator? Is 15,000 mile replacement too often for most people who don't have dusty conditions?

    I too not like the spongy suspension of my Bravada. I was going to talk to my dealer about the possiblity of upgrading the stock shocks and struts (if that will help stiffen it up and lessen the pitching and roll).
  • dshepherd3dshepherd3 Member Posts: 194
    Your theory is on target, but the advance curve built into the TB pcm has an upper limit, regardless of knock sensor intervention, this limit reflects the use of 87 octane, so unless you can reflash the pcm to alter to curve, premium will have no effect, unless of course you run into some junk 87 octane which causes a ping, then of course a switch to 91 at that time would increase the power.
  • aldan93aldan93 Member Posts: 202
    Get a $49.99 K&N air filter, all you need to do is clean it once a year and it is guaranteed for 1,000,000 miles!!! Plus is you put the sticker on the air box they "your dealer" or oil change place will not soak you ever, for that matter they will never even ask or look at it!!!! It will pay for it self in 5 years!! Plus it boosts airflow and HP so they claim. I have one, it seems my TB since new was getting around 16-17 MPG, since the switch to Mobil Gas<---No ethanol, and the filter change I have been getting 19-20 MPG 50/50 High/City.

    re tb4me

    Yep I'll have to upgrade the floor jack, mine is too small, ok for my Nissan, but little skimpy for my TB. I don't like going under vehicles with just a jack!!!
  • cebtebcebteb Member Posts: 138
    My '03 Bravada didn't come with the air filter indicator, so prior to leaving on vacation last month I visually inspected it. Over half of it was quite black. Same condition that would prompt my changing of the air filter in the Bravada's predessor, a '91 S-10 Blazer. With the Blazer, a new filter instantly brought back engine performance.

    I decided to change the Bravada's filter. The bad news is that replacements aren't available in the Walmart's or Checker Auto's in my area. Got a NAPA Gold for $21, pricey!

    My wife ran an errand right after I changed the filter and came back asking what I did to get the quick acceleration back. The filter. BTW, that was with only 6K miles on the Bravada. I live in Metro Denver so oxygen is a bit more scarce and they sand the roads in winter.

    pepper50, I recommend you change the filter. Too bad they don't have them for $10 at Walmart.
  • scottc454scottc454 Member Posts: 356

    Agreed about the TB, but I was referring to the Honda Pilot and its recommendation for premium fuel for towing.
  • scottc454scottc454 Member Posts: 356
    My wife ran an errand right after I changed the filter and came back asking what I did to get the quick acceleration back.

    You sure that it's not related to the recent temperature decrease around here? I notice a little more power in the cooler air. Also, the AC is off.

    Bilstein Shocks is currently the manufacturer of shocks for the TB, Envoy, and Bravada. Bilstien manufactures these OEM shocks and struts to specifications provided by GM.

    Bilstien is soon to release there aftermarket version which demonstrates a firmer ride, more control, less lean, without the sloppiness or hardness in the ride. They are normally completive priced right at $60 to $80 each and with all Bilstien Shocks carry a Lifetime Replacement Warranty. They will be worth the wait! By the way, the aftermarket Bilstiens are rebuild-able in case you still want them firmer or wish to soften the &#147;boom&#148; in a ride. The factory OEM&#146;s are not rebuild-able. Krupp Bilstein (corporate) has outfitted three of my vehicles in past years. I plan to outfit my new Envoy XL with Bistiens as well.

    15,000 mile intervals for swapping an air filter out is pretty typical, but if an indicator says it's good, then why swap it?

    The Edmunds Maintenance Guide will tell you what we think those 15,000 mile services should cost.

    All -

    I finally opened up the air filter box after almost 12,000 miles. My wife drives the truck locally most of the time - I would say we do 80% local vs 20% highway with the truck. However, the local driving is not "dusty" in my opinion. The bottom half of the filter was black and very dirty. Rather than just flip it over, I too went with the Napa gold filter for $21, as it was the only one I could find other than at the dealer. I did like how you have to take the cross member off to get at the filter.

    By the way, I don't think we'll ever see these filters at Wal Mart for $10. I also have a '00 Tahoe Z71 that takes the barrel style filters as well, albeit a little larger for the 5.7L V8. The Fram price at my Wal Mart is $17.

    In other news, the truck seems to have settled down a little in problems, after a little over a year. I did have another set of suspension links put in the front end to cure the "bumping" noise when driving on rough roads. That makes two sets in 12,000 miles. Come on General, fix it right for once.
  • tblazedtblazed Member Posts: 945
    There will likely be several ways to address the suspension.I am real happy with the combination of the stock shocks and the Hotchkis kit which firmed up the ride, greatly reduced the lean in corners and added stability. Only possible problem I see, those LINKS envoy_xl_in_pa has had to have replaced. Obviously firming up the front bar bushings and replacing the rear bar with a bigger one will put more stress and wear on those links. Time will tell. They're about $30 ea from GMPD so if they wear out I'll just buy new ones. No biggie.

    My A/C problems appear to have returned in my '03 Envoy XL. In April I had the low pressure switch replaced and that seemed to fix the problem with my A/C blowing warm air. It went out right after a 650-mile road trip.

    But today I noticed the A/C is occasionally blowing outside-temperature air again, even with the auto climate control set at 60. Funny thing, we just got back a few days ago from another 650-mile road trip. Coincidence?

    Out of curiosity I phoned 3 GMC dealers and 1 Chevy dealer in this area and got quotes of $25, $27, $29, and $32 for the filter (the Chevy quote was $27). So it pays to phone around if needing a dealer part, but the NAPA is obviously better deal anyway at $21.

    I have a new 2003 Envoy. Had a Murano which was wrecked when someone pulled out in front of me. Caused $12,000 in damage and we didn't want to keep a car with that much damage and it was also going to take a month to 6 weeks to get it repaired. Back to the Envoy. I have had some extreme wind noise on the driver's side. We have had the car in twice and this time they kept it for 3 days. Said that they had received a memo from GM regarding the problem. Something with the side mirror not sealing correctly at the factory. They made all the corrections that GM recommended but still have the noise. Has anyone else noticed this?

    For those considering a Murano vs Envoy I think they are very different vehicles. Since we have always drove GM vehicles, it was a little hard for me to get used to the CVT in the Murano. I still had not figured out all the buttons when it was wrecked. It took me a month to get the seat adjusted to where I was comfortable. It was a very smooth ride but always felt like the car was going to move forward just a little when you stopped. That is covered in the Murano problems discussion here at Edmunds. I got in the Envoy and felt right at home. As mentioned here in Edmunds, the interior could be a little better put together for a car that cost that much.
  • cebtebcebteb Member Posts: 138
    scottc454: That air filter change was August 15th. It was still plenty hot here.

    My point was that the Bravada responded to a fresh air filter just like my former '91 S-10 Blazer. A noticeable improvement in performance.

    The sensitivity to the air filter might be due to the altitude here or the dusty roads in winter and spring, but oddly, my other vehicles of this vintage didn't/don't respond to air filter changes. They included a '91 Geo Metro (don't ask) and a '99 Chrysler 300M. The Chrysler responds to engine cleaning chemicals, but replacing a really dirty filter makes little change in performance. Go figure.

    Too bad I won't be changing air filters as often with the Bravada due to the filter price.

    Filter change interval guides are just that, guides. One needs to evaluate for one's self and see what works for you and your vehicle. GM's pressure drop indicator, if you have one, can also be helpful, but remember it is a crude gauge at best. The guides and gauges are really geared to ensure the filter gets changed before it puts the engine at risk. Sort of like the oil change indicator in the DIC. They aren't necessarily geared to ensuring optimum performance and engine life from the vehicle.

    > Funny thing, we just got back a few days ago from another 650-mile road trip. Coincidence?

    Redline65: Same thing happened to us - A/C started blowing warm air after a 2 day roadtrip. Low-side cycling switch was replaced and has worked fine since. But we haven't done any long (over 2 hour) road trips.

    Sounds like that switch doesn't tolerate extended use.
  • redline65redline65 Member Posts: 693
    This is the second time this has happened to us after a trip (and we've only taken the Envoy on 2 trips!). Maybe it is somehow related to driving the vehicle for a long time. I hope the GM engineers know about this. I don't want to have to pay for these switches to be replaced after every road trip once my warranty is up.

    I took it to the dealership this morning and the tech said they have been seeing a lot of these low-pressure switches going bad. I'll post their fix later.
  • jr45jr45 Member Posts: 45
    Thanks for the info about the suspension. My Bravada rolls and bounces so much thatI began to wonder if one the shocks or struts was broken. I climbed underneath and none seem to be leaking or damaged. I noticed it has Bilsteins all the way around. Might wait around for the stiffer Bilsteins to be released since that's the cheapest fix.

    I suppose by making the ride so soft GM is trying to give customers what they want. To me, the squishy suspension negatively affects handling and control and gets to the point of being a safety issue.
  • discofeverdiscofever Member Posts: 34
    The aftermartket Bilsteins are planned to be released by the end of the year. I am told they will correct the sway and body role at high speeds, provide more control at low speeds and reduce leaning on turns.

    They will retain the smooth ride at all speed levels.

    Someone will have to explain to me how shocks can control the amount of body roll in corners. Somehow the sideways G-forces making it roll have to be controlled and the shocks work independantly of each other. Stabilizer bars work to counterbalance the sideways roll because they are attached at both L and R sides of the suspension and to the frame. Shocks independantly control and dampen the vertical movement of the wheels in relation to the body.

    Tblazed,

    You are correct, shocks are not the proper cure for sway and yaw issues. As we do on my race car, the first fix for the suspension is to install correct spring rates, then proper sized sway bars and finally shocks to attenuate the frequencies. Doing the larger sway bars and harder bushings should be done BEFORE adding shocks with increased damping in jounce and rebound. Some people will suggest gas filled shocks increase effective wheel rate but this is not really accurate and at best, a bandaid for bigger suspension problems.

    You are partially correct tblazed shocks do dampen the vertical movement of the wheels but they do not control it, that is the springs job.
    A shocks job is to control spring oscillation.

    Anyone using wheel locks on their triplet? Did you go with the GM or other brand? I saw the GM at the dealer for about $28. I'd hate for someone to steel my 17" wheels. Thanks.
