#12 of 89 2005 MDX Transmission Vibration @ 35 mph
Jun 26, 2010 (5:44 am)
Starting around 30,000 miles, I began to notice a vibration/grinding noise while accelerating through 35 to 40 mph. The noise would last for 10 to 15 seconds and then stop. I took my MDX into my Acura dealer at 35,000 miles while it was under warranty and they said they could not reproduce the problem. The problem continued to worsen however I was now out of warranty. I did some research on the internet and found 14 reports of the exact same problem on the NHTSA (www.hntsa.gov). Out of 30 total complaints, 14 were this specific transmission problem. I also found a 2004 MDX service bulletin (#6003; NHTSA # 10022468) that states "Torque converter shudder or vibration between 35 and 40 mph". I presented this info to the Acura dealer and they acknowledged the problem and agreed to pay for 75% of the torque converter replacement (the care is 6 years old and has 45,000 miles). Why hasn't someone started a class action law suit regarding this problem given the significant amount of data pointing to a general problem?

My 2001 MDX, while the AC is on, begins idling (engine runs hard) when I am at stop lights. I turn of the AC and it stops. Anyone ever experience similar problems? What could it be?
#14 of 89 06 MDX Torque Converter
Jun 30, 2010 (4:07 pm)
I have an 06 MDX had the torque converter replaced in Dec 09, June 30th,2010 back in for same problem. Dealer is telling me that Honda will do one of three things replace torque converter again, replace tranny or nothing until they have a for sure fix, evidentally replacing those things hasn't cured the problem in some cars..I am so frustrated don't know what to think, does anyone have any ideas or have heard of such a thing? Should I hire an atttorney?

Can you tell me, when you took yours back in, how many miles did it have on it? I am at 70,000 miles and I am wondering if they will still replace the torque (AGAIN) outside of warranty...I can tell you, I wont go silently if they dont...because its obvious they have a big problem with them.

The first tme I took in was in dec 09 2months after I bought the car..Second time was In feb and they did hear it , but told me it was the way I was driving it, wasn't loud enough so this last time june 30th 2010. It's definetly bad again, it has 59000. There definitly is a big problem, I've had this car 8 months and totaly disgusted. I would call American Honda Corp, to report it again the more you complain the better the chance for them to make it right. Not sure what their going to do for me, because obviously the torque converter didn't cure it the first time. I may have to talk to an attorney. All I know is they need to make it right, who wants to go through this every 6months or so. Good Luck!

Acura has decided to put new transmission in my MDX they didn't say they were going to replace torque converter too. Does anyone know why they shouldn't? A lot unsure about this car only had it for 8months,has already had torque converter replaced in Dec,09. Let me know any ideas.

I have a 2006 Saturn Vue with the same engine and transmission. Saturn owners have tried a few different things. Some people have drained and refilled with Honda ATF Z1 3 times, while driving a few miles in between, and that has worked. Some have had the PCM re-flashed. That seemed to work for a few days but the problem would come back. I think the problem is a mixture of bad calibration in the PCM and torque convertor wear. I have tried the refill and got no better results. Honda needs to figure out what is going on and fix it!!!! People are getting their torque convertors replaced and the problem is coming back. It's like replacing a faulty smoke alarm with a faulty smoke alarm. I feel like I wan to call Honda and Saturn and yell at them until I get a torque convertor replaced, but that is not fixing the problem, so what;s the point?
#20 of 89 2005 MDX Torque Converter Issue
Jul 13, 2010 (6:43 am)
Just picked up my 2005 MDX from dealer after replacing the torque converter. It appears that the vibration/grinding between 35-40 mph has now been eliminated. For background, I reported this problem in March 2009, a couple of months prior to the expiration of my warranty. The service tech stated that he/she could not reproduce the noise I was hearing. Over a year later, the noise was now continuous. I took the vehicle in and this time the service tech could hear the noise. I was told that the vehicle was out of warranty (45,000 miles, but over 60 months) and that it would cost $2,000 to $3,000 to fix the problem. I opened up a case file with Honda America. After several calls, I was offered a repair for $500. I continued to complain and mentioned that I had uncovered over 100 complaints for the exact same issue. The Honda rep. still would not budge on the $500 cost to me. Finally, I mentioned that I might pursue a "class action suit". He said he would speak to the district supervisor. Miraculously, he came back and said that Honda America could cover 100% of the repair. I would suggest that anyone battling this issue out with Honda America mention "class action suit". There attitude seems to change quite significantly! Good luck!

ust so everyone who follows this thread is aware, there are several other threads reporting the vibration/grinding 35-40 mph transmission problem (torque converter). The tread entitled "Acura MDX Torque Converter Scam" and "Acura MDX Repairs & Maintenance" also have reports of this same issue. Also, if you look at the Honda Pilot forum, there are several complaints of this very same issue with Honda Pilots. If you search for Canadian Pilot and MDX forums, you will find once again many reports of the torque converter problem. If there are say 500 complaints between all these forums specifically addressing the vibration/grinding noise while accelerating between 25-50 mph, it is obvious that there are probably thousands of Pilots and MDXs that have this problem. Many owners probably got their transmissions repaired under warranty. Many may have just born the cost if their vehicle is out of warranty and many may not be computer savy to investigate this issue on the internet. This is a much bigger problem than any one forum can address. There are probably many vehicle owners that have this problem and are not aware either because they never turn their radio down to hear it or have been told that the dealer cannot reproduce it. It would certainly appear that this issue would be a prime candidate for a "class action law suit". I am sure there are several law firms that specialize in "class actions" that would love to get there hands on this issue!!!
