    There was a problem with cylinder sleeves cracking in the 2002's. They admitted this and extended the warranty to 100,000 miles. I don't know if it's all 02's or just the early ones. You should have received a letter from them if your warranty has been extended.

    The extended engine warranty applies to all triplets built during calender year 2001. You should have received the letter last june if your mailing address hasn't changed since you bought your envoy. I have the letter saved as a jpeg file if you would like a copy emailed to you.

    Just wanted to see if anyone has experienced this noise. When I cranked the engine yesterday, I heard what sounded like a piece of paper being hit by a medium speed fan blade. Sounded like it was coming from in front of the console, and it was pretty loud. Noise was intermittent, and has not occurred again. Didn't seem to be affected by adjusting the AC.

    I have an '02 SLT 4WD. Any ideas?

    Did you check under the hood for cats, rats, or other dismembered critters?

    Is bulb replacement for headlights, tail lamps, blinkers, etc. covered under warranty? Thanks.

    My right side mirror now remembers everything…….amazing new feature ive reclaimed. I previously would hit the mem button several times before it found its original position at best. Its now worked for a whole week, since washing the truck. I had pushed the mirror to its limits left, right , up and down several times (makes a heck of a ratcheting noise) to dry the puddle that forms inside it so that it doesn’t splatter down the doors. I do that all the time but this time in four directions (not electrically) and the truck was running. Ever since then it works / remembers !! Someone with failing mirrors try this and we will see if it works twice or am I just lucky? Why would it start working properly?

    My guess is that it relates to the rear heat/ac system in the console. Every once in a while I get the same noise when the system shifts from one set of vents to another. Very rare but that is my best guess. If you pin it down let us know!

    "Is bulb replacement for headlights, tail lamps, blinkers, etc. covered under warranty?"

    I don't know what the official word is, but I had two brake lights replaced under warranty. Note that there is a defect where the brake lights burn out prematurely. There is a service bulletin on this and they will replace a circuit board to remedy it. Mine is fine after the fix.

    Steve - I read in one of the other boards that you have a Yakima Rack.
    Do you have it on your triplet and if yes, what length crossbars did you use?
    I plan to install the rack and carry 3 Kayaks on top. My tendancy would be to install the longest bars available (78") for the versatility.
    Longest recommended however are 58"

    My Yak rack goes on my Quest minivan. I used to carry two canoes side by side a lot when I was boating more, so I went with the long bars (78").

    Having a higher vehicle helps prevent the knock-out syndrome when you get out of the rig and forget the racks are up there (ouch!). But if you are tall, go for the narrower racks, especially if you are just hauling river kayaks. Those you can stack on edge and you don't really need the extra width as much.

    Mine are the tower kind btw, and usually live in the garage.

    Bulbs are covered under the 3 year 36,000 mile bumper to bumper warranty. They are not covered under any of the extended warranties offered by GM.

    About 4500 miles ago (39500 mi currently on the truck), I had my 02 TB EXT in for a repair of the front end clunking/rattling. They replaced one of the sway bar links at that time. It seemed to lessen the noise, but not totally eliminate it. I was OK with it at the time.

    Today I brought it back in because the noise was gradually getting worse. The service consultant had me drive around the block down some yucked up roads to see if I could generate the noise - no problem. They ended up replacing both of the links this time and now I'm amazed at the difference in the steering feel and the beautiful silence!

    On my way home, I took the worst roads that I could find and didn't hear a single clunk or rattle and I keep marvelling at the nice steering feel. I didn't realize how bad it had become over time.

    If you have any of the front end noise, make sure they replace BOTH of the links.

  • Thats interesting about warranty on 02s. I just purchased a 02 LTZ Trailblazer, 23000 mi. How would I find out if mine would be covered?
    Anyone tell me where to get a good looking splash garde for the trailblazer.
  • 01_hoe01_hoe Posts: 273
    Do you by any chance have the part #'s for the items replaced in your TB? TIA
  • ross1962ross1962 Posts: 229
    "...make sure they replace both of the links"

    Thanks for the advise. I'm actually going in soon to get this done. Do you know if the links have been re-designed, or if it's the same problematic design?
  • scottc454scottc454 Posts: 356
    Check the build date - it's on tag on the inside of the driver's door.
    If it was built in 2001, it's covered by the extended warranty.

    I'm not sure which is better, to have the extended warranty because of a possible problem, or not have the warranty because the problem was fixed.

    I think I'd rather have a build date in 2002 and not have the warranty.
    At 63000 miles, I hope I've gone far enough that my cylinder sleeves are fine.
  • dlaredlare Posts: 43
    They didn't write the part numbers on the sheet they gave me. I asked the service manager if they were redesigned or the same old thing. He said they're the same as the old ones.

  • kpp14kpp14 Posts: 62
    Heres what my work order said for the same problem:
    "Replace front sway bar link rods (loose rods causing noise)" R&R front stabilizer shaft at control arm. Link kit 12479231 and 12479233.

    Does anyone hear any clicking noise every time they press their brake while in park on their Envoy's. You can hear it coming from your gear shift. The dealer tells me it's normal.

    We just purchased a 2002 olds bravada. It's still under factory warranty with about 26000 miles. My problem is this. When making hard turns (right or left...doesn't matter) going around sharp corners, backing out of driveway, etc. the engine begins to run real rough and almost dies. When the steering wheel is straightened back up the roughness goes away. The vehicle has no problems going straight down the road. We took it to the dealer and he proceeded to tell us that all gm vehicles with 4wd or awd do this. It is normal for the vehicle. This sounds somewhat fishy to me, but I'm wondering if anyone else has had this experience or has been told the the same thing from their dealer. Thanks.

    this problem with a 03 tblazer; with mine i start it up in the morning after like 3 min or 4 min or so it starts vibrating, boom, sound. after i take off it gets louder when im at a light thats when it gets louder also when im in park. now i took it to a dealer also i found a tsb on it nbr 091903 now when i was at the dealer as usual they tried to jerk me which they did. i called chevy and some jerk was just like the dealer no help. but they said they talked to engineering and they said it was normal. they started up a 04 and it had the same problem mine was after 3to 4 min it starts to vibrate the 04 i was in was not even hot. i was at gm's site techlink 4-03 they clearly states how to fix this problem. now im at 29000 miles so i do not understand how they have a tsb about this and info how to fix this and you leave the dealership with the same problem? the doggone serv mgr tells me NORMAL!! now dont get me wrong if it is then i will be very dissappointed by chevy. i guess i probably will be looking at toyota since i cannot fit in a 4 runner. i was looking at it before i bought the t blazer sequoia perhaps? but im going to another dealer tommorrow and i will keep it running so they can hear it and bring the papers with me so they see whats the deal. i see the other dealership did not give a rats a... about my concern he did not buy it from us heck. i called the place where i bought it from and they are non comptent so as you see in northeast oh this folks are $$$$$$$$ hungry .in warranty do not mean a thing so what should i do folks. can someone find out some info so i can deal with this. lastly i want keep this tblazer so i will not have a car note now do you all think i should put a borla exhaust on it? i do like the sound. but i do want to hook it up know what i mean it but i do not want a lemon but anyway so help me please thanks.
  • It's normal. It is part of the mechanism that controls the transmission/brake pedal interlock. It is how the truck knows that your foot is on the brake pedal, to allow you to shift the truck out of park. It keeps you from shifting the car out of gear without your foot on the brake pedal.
  • mookie14mookie14 Posts: 252
    lost now when i start it up from it sitting over night and it warms up the vibration kicks in. like i said in the post before if they can lower the sound like they said could do at engine boom vibration 4-03 why have they not fixed the problem? if its the brake clicking noise i havent heard it. so im wondering what do you think? does yours do same identical thing mine does the same as mine yr mke exactly. let me know i would really appreciate big time you just dont know how much i would um what do you mean interlock all i do is start it up and in 4 min its sounding sick im at 29800 miles i have not heard this before. so i guess if you explain this in detail i will understand it as usual i would appreciate it ill wait for your post .
  • 01_hoe01_hoe Posts: 273
    I would not want my vehicle to operate like you described. This does not sound "normal" to me. Can your dealer show you this occuring in any of his other vehicles? My '03 Envoy 4X4 does not do this. I believe the dealer is jerking you around.
  • mookie14mookie14 Posts: 252
    now let me ask this i have a rwd not 4x4 now i am taking it to another dealer today or i have whenever you read this post. i do know the dealership i went to has a history of jerking folks around so i will stay away from them period. but what i am curious is about is well lets see what this other dealer says thats a very big thing. im still curious about is anyone having the same vehicle as mine 4.2 engine rwd ls 29000 miles or more and have the same problem as i am having. im made a complaint at the nhtsa so will see where that goes. anyone let me know you all are having the same problem as i am having thanks as again i will greatly appreciate it thanks again.

    I am about to purchase an EGR rear window dust guard for my '02 Bravada. Has anyone had experience with a rear dust guard. Do they work? My window collects dust big time. Thankx
  • allenrallenr Posts: 83
    The Smartrack AWD has had some problems. Does it feel like the front wheels are binding-up when turning, it might even feel like you are slowing down! If you make a tight enough turn the front wheels might even start to skid. If that the case it's the Smartrack is staying in 4WD.

    There is one or two TBS that will fix the problem. I know because it happened to my 02 Bravada. I'll see if I can find the TSB info.

    Pretty good news on a couple of things. First, bought and tried the Mr. Clean Auto Dry system on my Carbon Metallic Envoy last weekend. Call me a nut but I stood in the driveway for nearly an hour looking for a spot, a streak, something to find a reason to take them up on their money back guarantee. I couldn't believe it (still can't) but the thing came out flawless! I didn't have to dry it or touch it up anywhere. The glass, paint and chrome were totally spot-free. Paid $18 for it at Wal-Mart but given my hand wash hassle factor went from 2 hours down to 45 minutes, I'd gladly have paid $118.

    Also, Bilstein just released heavy duty shocks/struts for the Envoys and TBs about a week ago. A fellow Envoy owner from CA sent me a note with the part#s:

    Front / BE5-A333-HO Rear / BE5-A335-HO

    They have stiffer valving for apps with lower, stiffer springs. Should nicely round out my Eibach, Hotchkis and BFG Comp TA package.
