Driving on highway at 75-80 mph, car starts vibrating, and the steering wheel starts shaking. Took it to the deal to check since I have a warranty (only 51K miles) and they claim they cannot duplicate problem.

MDX 6-cyl

  • 107,600 miles


I own a 2005 Acura MDX touring, just purchased 3 weeks ago. 2 days after purchase a heard a grumbling/scraping noise coming from under the center console area, and over the past 3 weeks the noise has gradually started occurring more often. After getting an aamco technician to look at the problem he stated that the torque converter on the transmission would need replacing at a cost of $2,700. After researching online, several people have had problems with the MDX transmission across many year models, along with the Acura TL's transmission, all seem to be faulty torque converters. Many online bloggers have stated to me that even after getting the torque converter replaced it ended up failing again, anywhere from a month to a year later. Acura doesn't seem to have a real fix for the problem, they just replace one faulty part with another. This part, after researching online, seems to malfunction way too often, and I believe would be grounds for a company recall. My MDX is currently sitting in the garage until I come up with the money for the fix, but am extremely concerned it will just happen again. The fault in this part seems to be a design issue and not from normal wear and tear given the time between recurrences other MDX owners have addressed. Thank you for your time and I know that together we can address this issue, bring it to Acura's attention and then hopefully they will make this right.

  • 67,533 miles
Purchased a 2005 Acura MDX in September 2008 - approximately 48,000 miles - still under factory warranty. About 6 months later noticed a noise/vibration at about 20 - 30 mph while accelerating when car was cold. Around 60,000 miles this noise/vibration became more frequent and louder at 30-40 mph. This also began happening while accelerating. Would downshift to have power to make it over a hill or overpass without noise/vibration. Took to local Acura dealer in March 2010 to check out and was told it was the torque converter. Acura dealer replaced torque converter at 67,533 miles with new Acura torque converter (so I was told) - Acura paid for some of replacement. Car now has 73,400 miles on odometer and same noise/vibration is beginning. Noise/vibration occurs everytime you drive the car and once again is getting much louder and more frequent.

  • 106,705 miles
The 2005 Acura MDX that I purchased from an Acura dealer was brand new when I bought it. While the car was in my possession, I did not abuse the car and I performed all of the maintenance on it. Once the car reached 100,000 miles, the torque converter began to break and at 106,705 miles the torque converter had to be replaced by an Acura dealer. Replacing this torque converter cost me $2793.85.

2005 Acura MDX makes grinding noise when accelerating between 35 and 40 mph. This started occurring around 30,000 miles and continues to this day. There are many reports of this exact same problem on various automotive forums. This was reported to the dealer while the vehicle was under warranty, however, it was not addressed until I took the vehicle in approximately one year later with significant documentation regarding the problem. The dealership presented the case to Honda and they are willing to replace the transmission torque converter however I must pay 25%. this does not see fair.

The contact owns a 2005 Acura MDX. The contact stated that the vehicle had been experiencing a recurring failure with the transmission which would intermittently skip. The vehicle was taken to an authorized dealership where the contact was informed the failure was not a safety concern. The failure continued to occur and the vehicle was taken back to the dealership where the transmission was then replaced. The contact was told that the replacement transmission was new but upon speaking with the manufacturer, he was informed that the transmission was re-manufactured. The failure mileage was approximately 70,000. The current mileage was approximately 151,000. Updated 11/03/10.

Around 40,000 miles my Acura MDX 2005 began making a low groaning noise at 25mph and 35 mph took it to the dealer and found it was the torque converter. I also suspect that the transmission needs to be replaced due to the medal shavings in the fluid. This is the 2nd Acura MDX I have owned. The first was a 2003 but the dealer assured me that the problem was addressed in the 2005 version. Im thinking about a class action law suit.

I have a 2005 Acura MDX touring model which is making grinding noise which seems to be transmission related. This has been going on for about a year. I asked my mechanic to check it and he could not come to a remedy. I have read of other 2005 Acura MDX owners finding the same problem which means it is systemic/manufacturing flaw. This is an ongoing problem. I use premium gasoline so it isn't anything related to low grade gas. It is a loud grinding sound that happens when the car is just starting to get going, around 20-25 mph and if I slow down and accelerate again. I am sure it will continue to get worse. I also had the catalytic converter shield checked to make sure it wasn't loose and rattling and it was ok.

Beginning in 2006 I started to experience a hesitation and a hissing sound in my 2005 Acura MDX at hwy and local rd speed for the past three years I have taken the vehicle to the dealership only to get the same response of unable to duplicate. I recently took the vehicle to the dealership again on 11/09 and this time they were able to duplicate the problem which was a bad torque converter which required the replacement of the transmission. The dealer claimed the issue started at 58,000 mile and therefore out of warranty. The dealer wants $4000 to replace transmission. Still contemplating offer. I have discovered blogs that states an ongoing torque converter and transmission problem with the Acura MDX from 2001--2005 including a recall for 2001-2002.

I own a 2005 Acura MDX. This summer I began noticing a strange vibration and noise when accelerating in 4th gear. Also, the starter motor produced a grinding noise when starting the engine. After only 57,000 miles, I had to return it to the dealership for a new starter motor, torque converter and motor mounts. Fortunately, it was still under warranty and the dealership replaced all parts gratis. This was an expensive vehicle and I expected quality engineering. After reading about the ongoing issues Acura MDX is experiencing regarding torque converters and transmissions, I decided to put this on the record.
