    I've collected a list of known problems at the M-Class Outpost.

    Spraying some silicon spray into that area (along the base of the windshield/dash) and letting it work its way in for a few days solved the probem for me. However, I did mention it at Service A. FYI, according to the work order, "A-pillar trim fit foam under dash corner to realign corner of dash. Refit A-pillar trim". The slight amount of play that used to be there is now completely gone. It is as tight as the A-pillar trim/dashboard on the driver's side. No squeaks, no creaks. :-)

    There was an engineering oil class action against MB. Not sure what the model year coverage is, instead of 50k miles, I belive the engine warranty is extended to 100k for the engine oil problem.

    How do I get to the cabin air filter for replacement ? Is it behind the glove box like on the E's ? TIA. JMSinTX

    I have a '00 and at 10k it needed new brakes and at 26k it needed a new transmission. At one time or another all of the computer lights go on for no reason. Next time I'll buy Japanese...

    My upgraded Bose stereo on my 2001 ML320 Sport seems to have a reception problem. Most of the major stations in the Dallas, Texas area come in "weak". It sounds as if the treble cuts in and out just a bit. The CD works fine so I know it has something to do w/the antenna/tuner.

    Where is the antenna, in the windshield? .. and has anyone else had this problem?

    Thanks!

    I'm getting a popping noise coming from somewhere at the base of the windshield on the passenger side. I saw the post from Jan. and didn't know if this is the same problem. The service department can't seem to fix the noise. Any suggestions? Thanks.

    In the general M-class commentary I have read that several owners have had problems with false readings appearing.

    OIL HI frequently comes up because it takes 8.5 bottle of oil and somedays mechanics pour in 9 whole bottle.

    But the problem could result from a bad sensor.

    After a 4 day battle with my dealer, the truth came out that this sensor is frequently defective. Mine read "OIL HI" and then "-2.0".

    The sensor needs to be replaced and it happens so often the dealers keep a number of the replacements on their shelves.
  • I have a 2000 ML320 and this is the second time that I have been stranded due to a seized fuel pump. Am I alone? Also, I have had numerous problems with the air conditioner, side door film, easily chipped paint, cracked rear support, etc. I never expected the MB to have so many problems.

    Hey, Buddy You are not alone, It happened to me twice also, if you read my post a few months back, my fuel hose busted on me while I'm driving in a high speed on a highway my ML just died and that was one of the scariest moment of my life I have my family with me. I just thank god and I managed to pull my ML to the safe side of the highway. They replace it twice and so far up to this date I don't have any problem. Take it back to the dealer and have them replace.
    Good Luck,
    Jim
  • Did anyone experience this problem? I was driving on the highway, a couple of days ago, and I noticed the ETS light (second left on the dashboard) being ON. It stayed like that eversince, when the engine is started, with the exception of 2-3 seconds right after I started the engine ytesterday day.
    I thought it may be a fuse, and this is how I saw in the fuse box that F22 coresponds to cruise control + traction control (ETS) + ...
    The fuse was fine, but this is how I got to test the cruise control, that I don't usually use, and found out it's not working anymore.
    So, please, if anyone had this problem before me, tell me, what should I expect if I go to the dealer? Is the diagnostic free of charge? This would be my first time going to the dealership with a problem...

    Thank you in advance,
    Serban

    If your vehicle is still under warranty take it in and have thenm check it. I had aproblem on my BAS but not ETS.got fixed under warranty.
  • I have a 99 ML 320 and recently the fuel pump also died as I was trying to get the car out of the garage, I am so fortunate that I was not on the highway as "biker5" above! The dealer replaced it under warranty, however the other things - rattles in the rear door and the electrical problems (all warning lights go on for no reason, window motor dying, rear wiper motor quitting)I have had it with this vehicle & I am turning it in when the lease is up. This is my first Mercedes and I have really been disappointed by the experience. I am looking at Toyotas and VWs now.
  • biker5biker5 Posts: 199
    Lucky you, that you are still in your garage when that fuel pump failure happened to you. So you read my experience Huh!. But since they replaced mine I don't have any more problem...knock on wood.;-) anyway have the dealer fix all the problem, yours still under warranty right.

    Need information on ML320 2002. Inside air circulations turns off by itself every few minutes. Benz dealer says it is a feature, although it took a while for them to tell us it is a feature (over the weekend for the salesman). Can't find the feature documented elsewhere. Is this true?
  • mclass4mclass4 Posts: 3
    My new ML320 had a power steering leak and a faulty fuel pump after 11 days of driving. Anyone else heard of this happening?
  • don99lhsdon99lhs Posts: 9
    Last week my 2000 ML320 developed a tranny leak. It seams to be leaking around the rubber seal on the trans. pan. The bolts that hold the pan on seam a little loose but when you tighten them it leaks worse. What should I do?
  • rnursernurse Posts: 3
    Wow! I was really keen on buying a used, err uh, previously owned 2001 ML430. But after reading all this, I'm not so sure anymore. Is there a place where I can find out if there have been any recalls on this vehicle?

    trying to sell my used ML320.
    Having by far the lowest priced Y2k car in the paper tells me these cars are not selling,
    because the only interest I get is people who want to pay $26k for a car that sold for over $40k just 2 years ago.

    The dealer I bought it from offered $25k - and said only on a trade. I was so pissed off that
    I told him I would park it out in front of his lot with giant for sale signs on it and a price much lower than the $35k he asks for the very same car. The MBZ dealer thinks he adds value by certifying a car that is fully under warranty and has been meticulously maintained.

    I have a 98 ML320, when I'm driving with the AC on and I make a right/left turn, water comes out into the driver/passenger side. Dealer wants $100 to look into it. Any suggestions before I authorize the work. Thanks.
  • I have a 1999 ML430 equipped with about every option including the now discontinued/not supported 1st Gen slapped on Nav GPS system. To date:

    Wind noise at door seals - warr service
    CD failure - replaced unit warr
    Nav system failure - replaced unit warr
    Transmission computer keeps ML in kicked down passing gear after I back off on gas pedal. Asking dealer about this..
    Seat belt recall - factory warr service
    Front brakes replace at 25K
    Sunroof failed - full replace under warr
    Sun visor bracket breakage - warr serviced
    Spring failure in rear seats
    Cup holders knocked out of alignment by long legged passengers
    Nose angle of hood is prone to rock chips from other cars

    Overall the vehicle has been great. Outstanding power, handles like a car, unbelievable traction control especially in rain. Can get interesting in extreme emergency maneuvers like any HCG SUV. Short wheelbase makes it still bounce you more than one likes for extended highway cruising. Seats in this model are not as comfortable as my Explorer was or 2000 model ML is. I have 6 yr 100K extended warranty. Am looking forward to 2004 larger SUV Mercedes has in design right now.
  • Just bought a brand new 02 ML320. I occassionaly have an issue where it feels like the engine is not getting enough fuel so it starts shaking and eventually die. The feeling is similar to a manual trans where you are trying to mix the clutch and the gas so it won't die on you. They replaced the fuel pump at 4k miles and now at 5.5k miles, the problem is showing up again.

    Has any one seen this?
  • ckim72ckim72 Posts: 6
    have a problem w/ my 2002 ML320. the passenger side mirror supposed to tilt down when you put the gear in reverse and you can program it(angle of the mirror) to your memory seat. I tried to
    follow the manual for programming but didn't work. called the dealer and they said the manual was misprint and you can't program the mirror. I got the convenient pak. just for that feature b/c it is really useful when you do parallel parking in city. Is this true? They said I was the first one noticed it. Seems like nobody knows how to fix this problem.
  • orlandorland Posts: 9
    The sales brochure implied that it was standard. When I called 1-800-MERCEDES to ask about it, they said that the tilt-down function was part of the M2 package, which I do not have but you do. I would definitely call Mercedes and ask about it. I would also ask your salesman and/or another dealer.
  • ckim72ckim72 Posts: 6
    I've finally got an answer from the MB. regarding malfunctioning passenger side mirror. In order to activate the tilt down feature, you need to press memory button under driver's seat every single time you get in the car. I think it is the most ridiculous feature I've ever seen in my life. They keep saying that it was just engineered like that, no further explanation! I thought owning a MB. would give me a piece of mind, in terms of service and quality, but I was wrong. I've learned my lesson in a very expensive way. Think twice when you buy a MB.
  • jlangmdjlangmd Posts: 6
    I have no problems with my mirror tilt down feature. You do need to have the passenger side mirror selected on the center console switch for it to work. I have never pressed my memory button.
  • ckim72ckim72 Posts: 6
    Yes, I know that you need to select the passenger side mirror button to mobilize the tilt down feature. It seems like the mirror is working when I program it, but it doesn't tilt down once I restart the engine. Is my ML only one doing that?
  • Hi, we use our 99 ML320 for commuting to work and nothing else - all freeway driving. The fuel service pump died - but we thought it was a service issue - now we realize that it was not. It died twice. Every door lock has been replaced. And now the engine died at 80,000 and has to be replaced. Cost of new engine? 20,000 buckaroos for a new one, 9,000 for a used. We do have extended warranty coverage and they want to put in a used engine. I figure once the engine is in, I will have almost a completely rebuilt car!
    Mercedes has been extremely unhelpful about all the problems,except that the service guys have admitted that all of my problems (except the engine failure) are common to the ML320 - and not just in the 99 year.
    I had a jag before this, so I guess that this is just part of the "charm" of owning an ML320. But it irks me because I thought Mercedes was more reliable than jags. Looks like I made a mistake!
  • A Class Action Lawsuit was filed against Mercedes Benz that effects owners of all 1999, 2000 and 2001 Mercedes Benz vehicles. When Mercedes Benz implemented the Flexible Service System (FSS) in 1999, which permitted extended oil change intervals of up to 20,000 miles, they recommended changes with regular (fossil) oils. By 2001 they experienced some engines with excessive sludge deposits and early engine failures. They then recommended oil changes with only specific brands of synthetic motor oils to address this problem. Since Mercedes Benz initial recommendation for use of fossil oils resulted in not only engine failures of 1999, 2000 and 2001 vehicles, but also premature wear in others, a class action suited was filed against Mercedes Benz. Approximately 2 weeks ago, Mercedes Benz agreed to settle this suit by agreeing to extend the warranty on all 1999, 2000 and 2001 Mercedes Benz vehicles to 10 years or 100,000 miles, whichever comes first. In addition, the owners of 1999 vehicles will receive a total of $3,500 of service, of their choice, at a Mercedes Benz dealer.

    Hope this information shows that Mercedes Benz plans to stand behind their vehicles. I would think the Mercedes will be contacting owners of 1999, 2000 and 2001 vehicles in the very near future.
