    I just took 3+ hours to read the entire 50 something pages. If you are reading this because you have the same tranny problem like the rest of us....

    1) there is no permanent fix...only permanent fix is to get rid of the vehicle entirely
    2)PCM software update will not fix the issue
    3)replacement TC will go bad again
    4)replacement Transmission will go bad again
    5)If you are unable to get rid of the vehicle, it seems that the best solution so far is to push for entire transmission and torque converter replacement from Acura and get the 3 year 36k warranty and hope that if it goes bad again, it'll go bad within the warranty period.

  • So, we took our 2005 MDX (89K miles) for the Torque Converter recall about a month ago. After they "fixed it" we noticed it was still shuttering. So, we took it back to them and they REMOVED THE TRANSMISSION, replaced a few other things and the shutter went away. That was 3 weeks ago.

    Today, I was driving and noticed the D5 light started blinking. In reviewing other internet posts, it can mean the transmission is going out or a switch is overheating/failing. I'm not experiencing any other problems so he said that it is probably the switch and that sometimes that happens when a transmission is removed and put back in. So, I took it into the Acura dealership today and they are currently looking into it. On the phone, I said "it wouldn't cost anything to get the switch replaced...right?" He went on to say well if you don't have the extended warranty, then yes. I'm going to fight this one for sure...they had to pull the transmission because of the torque converter recall....I'm sure that is what is causing's just a coincidence that 3 weeks after they worked on the trasmission that now it the D5 light is blinking?

    Any suggestions?
  • Well I had the ECU remap done and I could see the problem lessen but it was still there occasionally. Now, about 4 weeks later, I suddenly get a tapping and check engine light. Within a few hundred feet the all wheel drive light comes on as well. A quick OBD-II check shows a cylinder 4 misfire but the engine was just inspected and the oil changed by the Acura dealer who performed the ECU remap a few weeks prior. Honda/ Acura will get one shot at fixing this issue if it ends up being somehow related to the TC. If they don't I'm moving forward with a lawsuit. Enough is enough. They knew/ know there is a problem, denied it, then throw out some half-[non-permissible content removed] patches which only work, according to a manufacturer service manager about 1/2 of the time and still let this to continue.

  • If I bought the car in 2008 Certified Pre-Owned from Acura...wouldn't this be covered under the 7 year/100,000 mile powertrain warranty?

    "..1) there is no permanent fix..."


    You could pull the fuses that power the drive to the rear clutches and dramatically extend the life of your transaxle. The other possibility is to put a switch in series with the power to the rear drive clutches and only power them under KNOWN low traction conditions.

    Dam WWest, who da hell know how to do that? Also, how do you know if that fixes it? How do you know if that messes with other parts of car function?

    I had my TC replaced by dealership under waranty and PCM update. It lessened the shudder but the problem seems to be still there, just not as loud. Took it back week later because it was making minor shudder/whining/whistling noise and complaied to dealer and asked them to replace the entire transmission and they would not. They said they ran diagnostics on the tranny and they could not find nothing wrong. Also they said that its the bearings that's making the noise and its "normal" compared to other vehicles so they will not even open up the tranny to look at it. unreal

    So this TC/Tranny problem is Normal guys according to my Acura dealership.
  • Do all MDXs have transmission problems? I am looking to purchase a new midsize SUV with a third row (MDX, X5, LX470 or XC90). I see that there are major transmission issues with the MDX, particularly in the 2005/2006 models. Does anyone know if the 2010 or 2011 will have the same transmission issues? Has Acura fixed the problem? I have not been able to find this info anywhere.

    Purchasing a car is overwhelming! It seems like all the cars have reliability issues. Any insight would be greatly appreciated.
  • Myself and several other 2010/2011 mdx owners are experiencing a slight metallic knocking noise in our vehicles at speeds between 0 - 25. Dealers cannot pinpoint the source of this issue. Someone that's a master tech at a forum mentioned that the noise is originating from the transmission. Dealers Acura/Honda are not being forthcoming if this is the case. Being in the situation I would not buy the mdx if I had to do it over again. But it may be something they can fix (pcm or knock sensor adjustment) Don't know.

    Having a $60,000 vehicle that sounds like its got a diesel engine was not part of my plan. Not knowing what's causing the noise for months now has given me a bad view of Acura. I've also been told by the dealer that its normal for the car to sound this way. Yeah so Acura intentionally made a vehicle that knocks.

    Did you ever find out what was wrong with your tranny? I am having the exact same problem on my 2001 MDX with 152k miles on it. Please let me know what the dealer told you. my email is dtvo2005 @

    During acceleration below 25MPH(20?) your "center diff'l" is locked, or at least partially so. On a highly tractive surface that will result in a LOT of undue stress on the drive train components. That stress level is often so high, say during a fairly tight accelerating turn, to the point that something MUST give.

    In an actual 4WD in this situation it would most likely result in "tire hop"/scrubbing as a way to relieve the additional stress. In the early VTM-4 MDX that "give" was obviously provided by the torque converter (lockup clutch?) resulting in widespread premature failures of that component.

    Your slight metallic knocking noise may be the result of slippage of whatever component, weakest link, must provide the required "give" when accelerating, even lightly, on a non-slippery, tractive, surface

    mother of 3, look elsewhere. Being mother of 3, this is headache that you do not need. I realize that all cars have problems but transmission/engine problems are the worst and most costly problems cars can have. You will not have a piece of mind owning an MDX. I'd lean toward X5 or RX350. I I believe BMW has 100k mile warranty now on power train, etc...Acura got rid of the 3rd row seat so all things being equal, X5 and RX350 comes out way ahead even if you have to pay bit more.

    eaaaeewwwwwww, I don't really consider 4runner a "luxury", "high end" though.....
  • wwestwwest Posts: 10,706
    Lexus GX or LX470 then..?
  • jensadjensad Posts: 388
    You mentioned "warranty" and Acura has a 100k for the mdx and the rl and I am sure for their other vehicles. We got one for our rl as we have in the past experienced tranny issues on other vehicles we had purchased. And after putting out $$ previously for previously owned vehicles, we decided to cover our axx this time.

    We learned from bad experiences and I hope the readers don't have to learn the way we did.

    Good luck to all and stay safe.

  • jensadjensad Posts: 388
    I need to add as I forgot about a 1978 honda that was used by our children that had a tranny failure. Fixed it and then we got another 10 k out of it and then old. Sorry for the screw up.

  • Yay for me! I just took my Acura MDX 2006 in and at first they were going to replace the entire transmission, but then they said it is only the torque converter. So more or less you are telling me the car I spent over $35K on is a piece of [non-permissible content removed] and I should never invest in honda again. I have 72K miles on it and planned to drive it for another 5 years. Does not look like that is the case...

    Has anyone thought of a class action suit? I asked if they planned to do a recall on the transmission and then stated "Since it is not a safety issue, we legally are not liable to"
  • dc1225dc1225 Posts: 53
    LOL Im in the same has 71k miles on it and they replaced the TC then PCM adjustment. Car still makes shuttering noise, I asked them to replace the transmission and they will not. Eventhough it makes shuttering noise, they said the transmission is fine. Deny deny deny.

    I am sure everyone would jump on board if someone would start one. I emailed they wanted to know more info but I do not have the time or the energy so I just gave up.

    I am probably going to have to purchase some kind of warranty because I am stuck with this car for 5 years. Are you planning on purchasing warranty?

    We experienced something very similar with our 2004 MDX and were told by one dealer that we need new transmission; but the 2nd dealer in San Jose told us that there were no evidence of transmission problems!! The Customer Service folks at Acura offered us to replace the transmission for $1,000 and when I told them that Lexus folks would have done this for FREE; they didn't get it!! Lexus had replaced our TIRES (consumable item) for FREE at 43,000 miles when we complained about the nose. Acura folks didn't get it.

    Lexus folks did NOT have to do this; but they did it; because they get the cost of customer acquisition. No such lessons have been learned by Acura USA!

    It's too bad for a Premium brand not to understand Premium Service. It's too bad because the cars have potential. Acura has a lot of work to do before they come ANYWHERE near Lexus when it comes to "Service".

    It's too bad.
  • dc1225dc1225 Posts: 53
    It is too bad. I purchased a RL previously and had very good experience with the car and just purchased the mdx and this transmission thing has been nothing but nightmare. Unfortunately, the only thing that we can do is NOT buy another Acura and believe me due to this I will never ever purchase another honda/acura in my lifetime. Lexus is the way to go...I was looking at RX350, X5, MDX and due to my cheapness, I fell prey to that 3rd row seating thing....never again.

    When it comes to customer service, Acura Client Services doesn't get it!! They are denser than San Francisco fog on a sunny Summer day! Lexus offered us FREE Michellen tires when we complained about the noise at 43,000 miles after a rotation and service at the dealer! And this was on a leased vehicle and on an item that Lexus doesn't make! Wow, we said!!

    Contrast that to Acura Client Services folks who they refused to cover the $1,014 charge that the dealer wanted to replace our 2004 MDX transmission. Ouch, I said!

    If you are looking for Premium Service; you won't find it at Acura! Acura USA is in the SAME place MBenz folks were before Lexus started kicking their [non-permissible content removed] to the curb. Ironically, MBenz folks have since hired some senior executives from Lexus and they have gotten much better at service.

    But there is no "culture" or "DNA"of servicing luxury customers at Acura at this point. If a class action law suit will straighten them out; more power to us; but I doubt it. I think they need a crisis of confidence like Toyota is going through to clean house.
  • what year is your MDX!? I thought the transmission problems were supposed to have been fixed after the 05 models!?
  • dc1225dc1225 Posts: 53
    No problem continues...mine is 2006. I think they stopped the Gov. "recalls" at 2004 which is why people think there aren't same problems on 05-06 but I am here to tell you that the problems still do exist on 2006. If anyone's interested in purchasing 01-06, forget it....I'd not purchase 01-06 MDX, don't fall for the 3rd row seating and interior spacing and reliability like I did.

    If you insist on purchasing MDX, look at 07 and on, not anything prior to 07. If you can't afford the 07, I'd look at other brands.

    I have taken my vehicle into the local dealer several times, regarding the whining noise. It became a game several times. I would hear it, take it to the dealer, and they would try to duplicate the noise, and couldn't. The first time or two, I thought I was going crazy. The third time, I was driving to the dealer and the noise was present. I arrive to the dealer, and they sent a senior tech along with me to show the noise. We drove around for about 15 mins, and to my surprise it didn't want to appear. I felt like a fool, and then said I am CRAZY. I drop off the tech, and leave with my tail between my legs. Two weeks ago, I went in for my 75k service. The following evening, the noise was louder now. I made an appointment, and was ready for the dealer to hear it this time. I dropped off the vehicle this time, and was told they will look into it. The next day, I called back to the dealer hoping to hear what was the cause of the problem. I spoke with the service advisor who said he has taken my vehicle out, and also had the senior tech and they can not duplicate the noise. I was ANGRY. I said, I am on my lunch break and I am on my way up there and wanted someone to ride with me to point out the noise. I was given the shop foreman to ride, and to see if he hears anything. As we leave the parking lot, and get onto the highway the noise started. He asked me to take my foot of the gas, which I did and the noise disappeared. He said apply the gas pedal again, and the whining noise came right back. The foreman even said, wow this is annoying (tell me about it). He said I just don't know where it is coming from exactly though. I even showed him when I switch into another gear it would go away. He said yeah, this sounds like a transmission or a bearing issue. This was music to my ear, because I am not crazy now. They are replacing my transmission, and it is being ordered as we speak. I also brought up the torque convertor issue I see on a lot of blogs. They told me that my vehicle would feel like I am going over a rumble stripe if my torque convertor was going out.

    I am happy, I hope with getting a new transmission under warranty. But then again, I wonder if this is going to fix my issue. Based upon other comments, some people are working on the second or third replacement now. With the transmission being replaced, should I also request for the torque convertor to be replaced as well?

    To date, I have had my timing belt replaced, under warranty, my blue tooth under warranty, a serp belt, and a strut all under warranty. I have only had this vehicle for three years. Is this a sign to trade in this piece of junk now?
  • wwestwwest Posts: 10,706
    The symptom you describe, whining noise under acceleration, is most typically (hystorically for me) an indication of a failing rear diff'l. Front Diff'l for you.
  • dc1225dc1225 Posts: 53
    MDX 32, That's the same god dam whistling noise that my acura dealer says its normal...bearing sound, basturds and won't fix so consider yourself lucky I guess.

    When does your warranty run out? If I were you, I'd keep it til the warranty runs out then dump it.

    I have a 2006 MDX and had thought for the past few years there was a transmission problem. I felt vibrations and hesitations between 25-40 MPH when excelerating. Honda sent out a notice in jan. that I needed to bring the car in for a computer program update designed to eliminate the problem I described above. It worked, car was riding smoothly as intended.

    Now I have a new problem.
    will start new message in the hopes someone can advise.
