    dlare: You may be correct in saying the computer ( DIC ) may not be exact. I don't know if the fuel added or used is actually metered at some point. I do know the DIC gives a fairly accurate estimate of driving range with gas left in the tank, if you continue driving the same speed etc. My point in comparing DIC generated gas mileage numbers was to have everyone use the same yardstick per se. I imagine all GM DIC systems use the same algorithms to arrive at the mileage number. That number will at least be a useful comparative figure. I would be more inclined to believe that than thousands of people filling the tank to whatever level they choose and then calculating their mileage in their heads. In baseball, they never give one game batting averages. The stats are lifetime averages.

    tblazed: we are saying the same thing with different words. The brake line scoring is the problem.

    funits: does your remote act up everywhere or just in one location? You may be experiencing radio interference at the location where it takes several attempts to unlock the door. Do you have a new ham radio operator nearby?

    I have the truck in the shop now and it seems that the dealerships in the NY/NJ area never have a loaner car . But anyway I am waiting on the scratches since we lease the TB ext I did mention it to the dealership . We will see what they do all the windows seem to have it. It is just the drivers side for you? I will let you all know what happens to it is in for 5 or 6 things this time .

    Could you please post (or email me my email address is in my profile) the specific instuctions as to what the dealer is to do to disable the override that can allow the transmission to be shifted out of PARK? Thanks!
  • tblazedtblazed Posts: 945
    jr45 since your Bravada is so new, what you see there is likely what you already have programming-wise. Keep that list for future reference. You will see changes as updates are issued. Check it every couple of months. If anything gets updated then you will have the original list to compare to. That's how I found several updates for my '02 TB. For example: the OS software for my TB has been superceded with 3 updates since my original printout. Otherwise the dealer has to plug in the scan tool, read what you currently have, upload that data to GM and get what versions you currently have and any of updates that apply. Of course if you are having problems it can't hurt to ask the dealer if there are any updates.

    "Funits: What results do you get if you use your other remote? Same intermittant problems?"

    Yes, I have tried remotes 1 & 2, and both work the same -- cold weather/winter everything works great, warm/summer you have to hit the button until it works!

    It may have something to do with sunlight, or the angle/direction of light in reference to the remote/vehicle?
  • momstruck1momstruck1 Posts: 206
    I made it a point that i would be returning the car at lease end and did not want to be charged for the scratches . was told by GM and now the service department that there would be no charge we will see. AS for the rest of the problems when I get the car back and get the paper work I will post what they did.

    I have the egr in-channel window vents and love them. IMO the stick on vents look cheap. Check out my site to see for yourself.

    The alternate transportation program on all GM cars and trucks provides for a loaner or rental if warranty service requires an overnite stay, why don't they get a car from a rental agency, GM reimburses them for this , it is part of your warranty.

    Just read on the I don't like SUVs thread that the new triplet motor is beginning to break.Is this something new or an anti SUV wish?
  • zueslewiszueslewis Posts: 2,353
    I've handled investigations on 5 engine failures in our area (PA, NJ, DE). I work with a GM service manager (17 years, out of the business a month), who related the silent recall.

    The 4.2 sounds great, considering hp and torque figures, and there are plenty of engines out there that have sleeved piston bores, but these aren't working, for some reason.

    And, no, you won't see anything published by GM on this - it would kill sales, of course.
  • tblazedtblazed Posts: 945
    Seems like an old topic. Haven't read here of any failures for a while after some of the initial ones failed made 6-01 or before as I recall. Thought all this was resolved over a year ago. One would think if this was still happening it would be all over the internet like the GM piston slap-knock issue. Isn't there a web site that can be searched for silent recalls?
  • zueslewiszueslewis Posts: 2,353
    I'm still seeing 2-3 cases a month - I handle about 35-40 GM cases (total) per month. No, it's not resolved.

    This discussion was sent over from another SUV discussion - sorry to drop in like this.
  • tblazedtblazed Posts: 945
    That's what this forum is for - information! Thanks for dropping in!

    I see far fewer lemon law cases on the GM triplets than I do on Explorers!
  • paulyjsobpaulyjsob Posts: 48
    I have a 2003 Envoy with build date 12/02. Does anyone know when they started using the 21 gallon gas tank? I always fill up before it hits 1/4 tank and I can't figure out what size it is. Thanks!
  • momstruck1momstruck1 Posts: 206
    a car for me because it always cost them more then the alotted 30 or 35 dollars a day with three kids and one in a booster they have to give me a larger car no the standered small one. I just have 25 payments to go
  • tblazedtblazed Posts: 945
    Seems I remember 8-02 was when they started using the bigger tanks.
  • tblazedtblazed Posts: 945
    zueslewis: Very interesting. Of the triplet cases are there about as many newer ones mfg. past 6-01 as the older ones failing? There was supposedly some "fix" done at some point past 6-01. The Explorer thing though is more interesting in that the TrailBlazer rose from nothing to #2 in sales behind the Explorer (maybe from people hoping for something better than their Explorer experience??)

    I have a 10/02 built tb. It has a 22 gal tank, on the tag in the glove box the code for the big tank is NNK. Im not sure if GMC is the same but it dosnt hurt to look
  • paulpropaulpro Posts: 56
    Can anyone tell me how quiet the in-channel window vents are. I do a lot of highway miles and can't ride with the window cracked for all the noise

    My 2003 Envoy XL (build date 12/02) has a 25 gallon tank.
  • zueslewiszueslewis Posts: 2,353
    these cases started showing up just 6-8 months ago, but then I haven't ever checked the build dates on the rigs in question.

    The only fix I can think of is what they're doing to the ones that break now - installing remanufactured engines - the ones that failed and were rebuilt.
  • jr45jr45 Posts: 45
    Every engine has its weakness. I had a '99 Camaro with the 5.7 LS1 engine and most of the failures came from spun main or rod bearings. In the forums a lot of guys would report spinning bearings -- then again, they were probably racing or otherwise running the tar out it. Maybe the same thing with the 4.2.

    Remote Keyless Entry Inoperative (Reprogram Liftgate Module)

    2002-2003 Chevrolet TrailBlazer, TrailBlazer EXT
    2002-2003 GMC Envoy, Envoy XL
    2002-2003 Oldsmobile Bravada

    Some customers may comment that the Remote Keyless Entry (RKE) is inoperative at times.

    An anomaly has been identified with the software in the Liftgate Module (RKE functions). The Liftgate Module software is affected when the temperature is approximately 40°C (104°F).

    Using normal SPS reprogramming procedures, reprogram the LGM Liftgate module. The information was released on TIS version 2.75 or newer broadcast in March 2003.

    zueslewis: My 2002 TB engine quit after 2160 miles in Oct. of 2001. The diagnosis was a loose cylinder sleeve. They replaced the engine with what they told me was a new "off the assembly line" engine. Prior to that failure there were no postings about failed engines. I wondered if they really gave me a new engine or a rebuilt one from someone elses truck.

    Going back to when the engine quit, I remember the night before it quit, I started the TB and got on the expressway after a few minutes and had to floor it hard to get out of the way of a semi. The engine was still cold when this happened. The next day is when it quit. I don't know if this had anything to do with the failure. The new engine with about 15 k miles has been faultless so far.

    My TB has never seen temps this high and I had the problem during the winter.
    Very intermittent and only a slight annoyance

    I don't think I've seen the owner's center discussed here in this forum. Are people using it? I've been using it for about a year on the Bravada and I just added our new Grand Prix to my vehicle list. I find it useful for the maintenance reminders, on-line access to routine service information, and for maintaining a service history. The information can also be loaded to your PDA.
  • zueslewiszueslewis Posts: 2,353
    either e-mail me with the part number off your invoice or call your parts department (in a nice calm tone) and say - can I run a part number by you to see if it's new or remanufactured?

    The "fresh of the assembly line" seems to be the line most service advisors give out, with any manufacturer's dealership, not just GM. I know, I was a service advisor/service manager and my guys would use that line, until I stopped them.

    I have just purchased an off (2 year) lease 2002 Envoy SLT (iniglo blue). Prior to this I read probably 75% of the posts here over the last 4-6 weeks. Despite many of the issues here I liked it and I bought it anyway. The truck was built 2/01, sold 8/01 after having the control arm recall fixed before it was ever sold. I was able to access the GM database and was able to see the build order, all repair claims, etc. Besides the 1st recall the only other repair was an A/C controller replacement and a rear door adjustment. My truck is a more basic SLT, with the cassette (non-Bose), running boards, upgraded wheels, and heated seats. No sunroof, no air suspension. It has 26,000 miles and I paid $22,700 before tax/fees. I'm hoping since it has a pretty clean history I bought a "good one". I am 43 years old, change vehicles every 3-4 years, and this is my first domestic vehicle in 20 years(last GM product was a Chevy Vega!). I have owned mostly Japanese cars, this is also my first truck. I looked at all the Japanese vehicles and decided I wanted a true SUV, not a tall, all wheel drive Camry or Accord. I love the appearance, the seats and the ride. I have it at my local dealer for its Maryland state inspection - they already told me it needs brakes and wiper blades to pass inspection, which I sort of expected as part of the inspection racket. I think this is a great board, thanks to all who share their thoughts here, I will participate as needed as I get used to the Envoy. Sorry this was so long. Craig
  • I got the service engine soon light today. I read the owners manual and it says to check the gas cap. well sure enough it was off. in the manual it also says it is supposed to correct itself. how long should I wait till it goes off. or should I take it to the shop.
