Acura MDX Transmission Problems



  • wwestwwest Posts: 10,706
    Undermine, no, just more detail, more depth in the explanation.

    First, since about 2005 to improve FE the lockup clutch is engaged at any and all speeds EXCEPT under acceleration or when the brake are applied. That's why I often refer to transaxles as having 6(10) speeds, the lockup clutch use is enabled in the top 4 gears.

    "..the 4WD drive system.."

    Get into an actual 4WD, transfer case, and with center differential LOCKED, drive it for, say, 20 miles on a highly tractive surface and then take it directly to a shop for repair. The only difference is the MDX has the "center diff'l" LOCKED only under acceleration or during low speed turns.

    But sooner or later you will have accummulated that same highly stressful, OVER-STRESSING, ~20 miles.

    I have about 20k more miles to go. I have another issue now, and I think it is time to say good bye to Acura.

    what's the other issue?

    I know I am through w Acura after this mdx. I am finally going to pay slightly more and move up to Lexus.

    my 04 has made the same whining noise ever since I got it 06 with 54k. I never did anything about it and have not had any problems

    that's great to hear...I hope I follow the same route as you. How many miles do you have on it now?

    Unless you mean the GX or LX, which have gas-guzling V8's, a new MDX would be a better value.

    The 99-00 RXes were dogs insofar as premature transmission failures.

    The newer, 2010 and after RX350 models have a muchly improved F/awd system but still remains FAR below the F/awd standard set by the SH-AWD system.

    It appears that the early failures of the MDX transaxles/TC were the result of the use of the VTM-4 F/awd system.

    On the other hand, for the new RX or the MDX (or even the new Explorer) I would disable the rear drive engagement clutch except for times of suspected need.

    No reason to needlessly chance a transaxle, TC, rear clutch system, or PTO failure.
  • I bought my first Acura in RL and it was magnificent ..never a problem. In 2005 I bought an MDX and has been relatively trouble free. 2 months ago I got the recall notice for "electronic upgrades " for the transmission. I took it to the dealer and in 2 hours they "fixed" the transmission by adjusting the shift points electronically. Now my miles per gallon have gone from 19 city down to 14.8 MPG and the highway mileage has gone from 24+ to 19.7 (or less). It feels like the top gear (overdrive ?) has been eliminated. Since we had had no problems before they did the work I asked that they return it to the original shift points so I could get my 25% mileage reduction back...they refused and gave me the phone # for Acura national customer I have to decide between MPG similar to my Ford F-150 V-8 or a transmission doomed to failure...pretty crappy options for a $45000 automobile..the last Acura I will own...anyone had a similar experience ??? Is there a class action suit ???

    I have no knowledge of a lawsuit but my 2003 MDX had the same gas milegae drop after they replaced my transmission. You solved that mystery, thanks. next car will be a Ford.

    Good luck re: "moving up to Lexus". I owned an rl330 and the hourly rate for the servicing for the Lexus was twice the cost of servicing my Acura rl, and now mdx. And the parts for Lex was likewise more than Acura.

    I figured the Lexus would continue to be expensive compared to my Acura so I switched over to Acura.. Both are excellent vehicles but I'll stick with my Acuras.

    Good luck to all and stay safe.

  • I know this is kind of an old post bt problem with my ut I am having this same exact problem with my 01 MDX and was wondering if any one has any info about it before I take it to a mechanic!!

    I have a 2006 Acura MDX with 83000 miles on it about 20000 miles ago it started to make a rumbling/vibrating noise at 45mph going up a slight hill. The tach will jump back and forth while doing this. Also while i was backing out of a parking lot i moved into gear and felt a shuttering from the trans as if it was slipping. to add to this while i was pulling out of an intersection the tach would not go above 2500 and go out of 2nd gear with the pedal literally on the floor nothing would happen. besides the trans problems multiple other problems have started. the dvd player quit,homelink never would work no light or anything,the adjustment handle on the passenger side fell out, the leather center console has had peeling leather, rust on the back door and security problems. we have always had chevy/gmc cars and trucks all over 100000miles with little to no problems they will run for ever. compared to this [non-permissible content removed] crap. save time and money buy American! will never buy another "Crapura" :lemon: :sick:

    "we have always had chevy/gmc cars and trucks all over 100000miles with little to no problems they will run for ever"

    If your chevy/gmc's were so great, why didn't you stick with them?
  • dc1225dc1225 Posts: 53
    because its chevy/gmc and some people don't want to be lumped in w the farmers hilbillies and low class people that drive them.

    A Honda product normally gets 250k to 350k miles, a lot better then GM. Also, GM products have high failure rates with their electronics, and they won't stand behind all the experimental failures with the Cadalac products. It's just that Acura dropped the ball on the MDX.

    Keep in mind that GM is just an middle-rate product. Acura is suppose to be a premium model. Maybe they hired some GM engineers?

    It's common knowledge that the forgien companies are learning to make cars cheaper in quality. My next car will be a Ford.

    "...why didn't you.."

    Wanted to try out some of this new, more exciting, technology...?
  • wwestwwest Posts: 10,706
    Ford, FORD...!!!

    These days to get a decent Ford you have to have the kind of deep pockets it takes to buy a Lexus.

    LOL so I get a letter from local Infinity dealer telling me that they would give me 20,600 for my 06 mdx. I guess apparently people are looking for used mdx and that they are having hard time finding used mdx.

    My cars worth 21600 according to KBB(excellent). This got me thinking maybe i can dump my mdx and get a hummer h3?

    Anyway, guys, apparently used mdx's are very much in demand right now so I guess you will get back every penny and then some if you decide to unload it.

    But then I just read this article today about used car prices are going up unbelievably. I noticed that edmunds 06 mdx rating is 4.7 even w the tranny issues. 0621,0,5778742.story

    "We need your car" letters have been a marketing tool for dealers for a long time.

    If you want to trade, go check out your options. Used car prices are nuts right now so you may indeed like the deal offered. Don't get your hopes up too high - Kelley's numbers are asking prices. Check for the TMV under the Used Cars tab above; chances are it's a bit lower, especially the trade-in value.

    But the letter isn't unique to you or to MDX owners (but you don't have to let the dealer you know that). :shades:

    hahah, yeah the thought REALLY crossed my mind let me tell you as I continue to hear my torque converter whistle....I am on the fence. The thing is I can get a 06 07 hummer w 60 70k miles for 15 to 17k, no problem in my area.

    I have to research da hell outta H3 about reliability. I am not about to go from a headache to a bigger headache or migraine! If the H3 was 7 seater, I'd be at the dealer already.
  • kyfdxkyfdx Posts: 27,643
    The H3 is just a re-bodied Envoy/TrailBlazer...

    I'd guess that reliability/repair is poor..
