2006 Acura MDX 77,000 miles bad torque converter. My concern is I am warranteed until 10/2012 or 100,000 miles what happens if this happens again and I do not have a warranty. There are quite a few complaints in regards to the torque converter going on Acura MDX from 2001-2006 models at low miles.

2006 Acura MDX shudders and vibrates when accelerating, approximately between 30 - 40 mph. The shuddering is predictable, occurs nearly everytime the car is driven. Acura service advised us the torque converter is slipping internally and needs replacement (in writing). Now Acura service states they will conduct the transmission software update which should fix the issue. The car is still under warranty, however, only 1100 miles are remaining on the warranty. From researching the issue, it is clear other Acura MDX owners are experiencing similar issues. The dealer told me they had never heard of this issue when I originally reported my concern in November 2010, however, they would look into it. The issues being experienced with this car appear to be on par with other MDX transmission issues, this appears to be nothing new.

Acura MDX 2006 at 70,000 miles began making a grinding noise, sporadically at first, when car was running between 30-35 miles per hour. RPM's also jumped when grinding occurred. Took it to an independent transmission shop and was diagnosed as needing a new transmission. Took it to an Acura dealer for a second opinion. They diagnosed it as needing a new torque converter. Now in negotiations with Acura for the repair.

I currently own a 2006 Acura MDX. The vehicle currently has 86,000 miles and has been serviced exclusively by Acura. All recommended services have been performed by Acura. The car was just returned to me after having its 3rd transmission replaced. This time the car broke down during an acceleration onto a major highway almost causing a traffic incident. The transmission has been identified as a failure by Acura and has been replaced by them each time under warranty.

Torque convertor failed at 81,000. Replaced at dealership, very expensive to replace and no guarantee it won't cause problems to transmission or transmission will need to be replaced.

I bought 2006 MDX May 2010 with 107,000 km, now coming to 110,000 after putting 3K I am starting to get vibration/shudder/grinding between 40-65kmh while accelerating, lugging power when I turn right or left on slow 20kmh. I guess this vehicle still under power train warranty to fix this issues or do I have any other option to resolve this issues.

I have a 06 MDX torque converter was replaced in Dec 09, June 2010 back in for the same thing. Honda doesn't have a for sure fix, so it is possible I will have to drive it until they come up with something else that will fix the problem. Who knows how long that will take? this problem is unfair to those of us who own these cars, Honda needs to make this right and not be allowed to get away with this. I've owned this car for 8months, the dealerships are all aware of the problem with these cars, but failed to disclose this information. I've enjoyed this car maybe one month before the problems arose. Need help!

2006 Acura MDX can be stopped and keys removed without shifting to park. We noticed this in an incident in a shopping mall parking lot when car was parked and mistakenly left in drive. Keys were removed and cars started rolling as if it were in neutral. Since the incident we have verified that keys can be removed when it is not in park. The car will roll freely when it is in drive or reverse. From another report on your site on 3/24/2009 we are not the only ones with this issue. While there was no loss for us this appears that it is an issue that needs to be addressed.

I have a 2006 MDX and when it had about 55,000 miles on it I started to notice a shaking/lurching feeling when going about 30-40mph while accelerating. I took the car into and Acura dealership and they replaced the torque converter, under warranty. When I picked the car up they said that it should never happen again and if it did then there should be some kind of recall done. Well, 10,000 miles later and it is happening again. I took the car back to the dealership and of course they can't recreate the problem which means they don't have to fix the real problem. The car is no longer under warranty!!

I own a 2006 Acura MDX with funny sounds coming from drivetrain area. If U decelerate to 30-40 mph, then slightly accelerate, there is a vibrating/shuttering sound followed by a clunking sound as attempts to shift gears. I had a service manager ride with me and he said he has never heard about this. I did some research and found out on edmunds.com that there are numerous consumers having the same issue and they had to have the torque converter and in most cases a new transmission at their expense, because the car is out of warranty when this occurs. I am about to be in the same position, since I am having noise issues, I imagine it is only a matter of time before I have to have it replaced at my expense. I was told there isn't a recall as of yet on the 2006 Acura MDX, but read many people having this same issue. Can you please help me because I can not afford to outlay 5000 to 6000 dollars due to manufacturer's issue.

Acura MDX transmission failure / catalytic converter.

2006 Acura MDX with 68,500 miles has a shudder feeling at speeds between 35 and 45 mph. The vehicle has been into the dealer twice and the service technician has stated that it is a torque converter problem, however refuse to fix the problem.

I recently purchased a 2006 certified used Acura MDX base model. I was exiting the vehicle and accidentally left the gear in park (automatic transmission). I removed the key without noticing it was in drive and when I got out of the vehicle it started rolling backwards. I noticed and jumped in and hit the brake, but was surprised to realize it was in gear and allowed me to remove the key. So I tried again and same thing happened whether I was in drive or reverse, I am able to remove the key and the car will roll like it is in neutral. I cannot reinsert the key without moving the shifter back to park. I believe this is an issue with the vehicles interlock after doing some research on similar incidents with Jeep and Pontiac. This is very dangerous and I would really like to see a recall be done to fix this problem.
