Automatic Transmission Torque Converter problems of the 2005 Acura MDX - part 1

As driving to work the vehicle all of a sudden stop shifting gears in the middle of the highway I was lucky enough to be able to stop to the right shoulder lane without getting into an accident. Prior to the car not shifting gears I heard a grinding metal noise coming from the middle of the engine, a noise that I've been hearing for the past couple of weeks. Come to find out it was the torque converter apparently it's a known issue that has been forwarded to Acura but they have done nothing in reference to it.

There is a grinding noise when traveling 35-45 mph. The dealership says the torque converter needs to be replaced.

When traveling between 30-45 mph car has vibration and grumbling sound as if difficulty in changing gears. Took car to Acura dealer and was told torque converter needs to be replaced. I had the the transmission flushed and hoping to have the car recalled since this seems to be an issue with other Mdx's. Was quoted $3111 plus tax to replace torque converter and think this should fall under a recall due to faulty equipment. This is a one owner vehicle maintained by Acura service center and this seems unusual to have a torque converter fail at just over 100,000 miles.

I have code p0740 which is tcc function. My trans is operating erracticaly and undriveable. After faithful service intervals the trans died in my car. Acura denies knowledge of the problem even though there are thousands of people their torque converter failed due to a design flaw. I was almost killed when the trans shuddered and stalled innthe middle of the road. I am furious this car is expensive and no need for transmission failure at such low mileage. Please recall and help.

Transmission rough and noisy starting on 35 mph. It needs a torque converter and transmission replaced. These car is become dangers to drive, you don’t know what to expect any moment. This should be a recall due to many many other owners having the same issue. I just call Acura customer support and them sad that I have to pay for an estimate ($200-300) and then ($3000) for work which should be done, because warranty is expired. Is this some kind of catch for the customers right after the warranty period? it is too many complains on 55,000 to 80,000 miles for that car. Is this something that Honda invented to collect more mony from the customers? I perconaly cannot trust Honda anymore. This is redicules, a specialy if you compare the price on this car, which is already overpriced based on the fake reliability. That issue must be recalled by Honda immidiatly, if they want to keep good name and not follow the Toyota, with their problem. I was thinking I am buying god car, but I purchase nothing but the trouble.

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 it. . . . It's just a coincidence that 3 weeks after they worked on the trasmission that now it the d5 light is blinking? I don't think so.

2005 Mdx. Within one year of purchase, a high pitched ringing was identified to the Acura dealer. Sound was dismissed as normal. For the next four years the sound recurred on acceleration and uphill driving. At 64,000 miles the ringing sound was diagnosed by the dealer to be a failing torque converter. Torque converter was replaced by the dealer (warranty). One year later, the transmission began making a rumbling sound while accelerating between twenty and thirty five miles/hour. Also, the ringing noise re-emerged. Car was taken to dealer. Dealer informed us that there is a recall on our Mdx regarding the rumbling problem--told it is an electronic problem requiring a one hour fix. (though at this time I can find no information about this supposed recall). The Mdx was given to dealer for fix. After the first day, dealer informed us that the fix had not solved the problem, and they would try again (at the direction of Acura technical support) the next day. Again, the dealer informed us that the problem was not fixed. Dealer's mechanic has told us it is the transmission that is faulty, but unfortunately Acura technical support is refusing that diagnosis. The car is now going on its fourth day in the dealership and we have been told by the service adviser that Acura is unwilling to address the problem beyond the electronic adjustment. We have been advised by them to drive the car until the problem gets worse, then bring it back. The problem, prior to dropping the car off at the dealer this last time, occurred almost constantly while accelerating slowly between 20 and 30 mph, at times feeling as if the car may stall. It has yet to pose a safety hazard, but has completely eroded our confidence in the vehicle's ability to take extended trips. Fear of breakdown keeps our trips limited to twenty miles or less. We have spoken to a lawyer and will file lawsuit if Acura does not address this obvious and unacceptable flaw.

There's a shutter when driving between 35-45mph. I have read a few forums on this issue and it seems there is an update from Acura but, I have not received anything on this matter. According to other owners this has not fixed the issue. Other owners have to replace torque converters and even transmissions due to a manufacture defect which is not fair at all to us the consumer. Please help us.

The contact owns a 2005 Acura Mdx. The contact stated that while driving she heard an abnormal grinding noise. The vehicle was taken to a local mechanic who performed a diagnostic that located the failure at the transmission torque converter. The contact stated she had previously received a letter from the manufacturer in regards to the failure. The dealer advised that the letter was sent to caution owners about the possible failures and that the computer would be updated to prevent the failure. The dealer advised that because the contact had already experienced the failure, they were unable to assist. The vehicle was not repaired. The failure and current mileage were 80,000.

Torque converter slipped - failure of transmission - Acura Mdx 2005.

2005 Acura Mdx. A shuddering noise is heard between 35 and 45 miles per hour and the engine speed increases by a few hundred rpm. Most often occurs while holding this speed on a slight incline or level. Torque converter was replaced at 78,209 miles on 11/18/2009. This temporarily resolved the issue, but the problem recurred and the torque converter was again replaced at 89,370 miles. This failure rate is excessive.

My 2005 Acura Mdx is making a shudder or grinding sound between 25 and 40 mph while accelerating. I have found that this is a common issue and is related to a faulty torque converter. Nhtsa has issued a "service bulletin" for this exact same problem for all Acura's for model years 2003-2004. This bulletin has not been issued for 2005. All should be recalled and corrected at Acura expense. Nhtsa item# ch. Cfm 10022468 "torque converter shudder or vibration between 35-40 mph" .

Torque converter shudder or vibration between 35-40 mph.

2005 Acura Mdx torque converter failing at 75,000 miles. Reduces my ability to accelerate and has put my in a very dangerous situation when merging into traffic.

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.

I purchased the car pre-owned from the original owner. I have all their service records and all service was done at the Acura dealership. Within a month of purchasing the car at around 70k I noticed a grinding or growling noise when accelerating at low speeds between 25-40mph. Within a month it started to happen almost every time I accelerate. About a month after that around 73k miles I noticed that I have a vibration when accelerating at low speeds. I haven?t taken it to the dealership as of yet because my old Honda dealership I no longer trust, and the Acura dealership near me has extremely terrible reviews. I have had my mechanic look at it when this first started to happen and he believed it could be the torque converter. I owned a 2000 Honda accord before this and Honda eventually extended the transmission warranty to cover bad torque converters. Honda/Acura is aware of this issue and they are not being responsible.

Defective torque converter 2005 Acura Mdx.

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.

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.

2005 Acura Mdx has had issues on multiple occasions where the transmission vibrates or shudders at about 1200-1400 rpm and under a light to moderate engine load. The torque converter has been replaced twice and the issue is starting again. Mileage on vehicle is about 80k.

Had to replace the torque converter on my 2005 Acura Mdx. Seems to be a problem just by searching the internet. Now I hear a groaning noise in the rear as I accelerate and turn the wheel at low speed.

2005 Acura Mdx torque converter jutter at speeds of 25-40 mph.

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.

Transmission / torque converter judder at approximately 30 mph when applying light pressure to accelerator. Acura dealer applied 1255a9 software update, which seemed to correct the problem for awhile. The problem began reoccurring approximately 1 year later.

2005 Acura Mdx transmission rough and noisy between 35 and 45 mph. It needs a torque converter and transmission replaced. This should be a recall due to many many other owners having the same issue.

At 30 -45 miles per hour, get a rumbling noise. . Took to dealership and had to have torque converter changed.

Shuddering and wash-boarding, due to defective torque converter. Acura mailed out transmission software updates December 2009 and November 2010 to address this on-going issue. I have kept mine and can send you the documentation on it if you would like to receive it. Neither software updates fixed the issue. Now they are saying we need to replace the torque converter. This is a well-known safety hazard (check out the internet forums on it) and can cause fatal accidents. Please consider a recall, especially in light of Acura's knowledge of the issue and unwillingness to fix it the proper way by replacing the part. This cannot be fixed by a mere software update. This issue is just as big and on-going as the Toyota issue. Please issue a recall on this issue. I understand that some of the Acura sedans (tl's) also have this same transmission problem!!.

I have approximately 57,000 miles on my 2005 Acura Mdx. I had been experiencing a noise coming from the engine at speeds around 20 - 25 and 40 - 45. I was told by the dealer that I needed my torque converter replaced. This appears to be a common problem on this particular vehicle. I feel that is unacceptable on a $40,000 car with so few miles/years on it.

I took my 2005 Acura Mdx in to the dealership to have an unusual sound checked out. It occurs while accelerating slowly to about 40mph. I was told that the torque converter needed to be replaced. I had a warranty purchase when I bought the vehicle so I did not incur any expense for this repair. The next week, the d4 light was blinking indicating a possible problem with the transmission. I took it in again and I was told that the 4th gear pressure switch was probably defective, as it was just replaced along with the torque converter. Ironically, a friend was having the same problem. She took her 2005 Mdx in for service, had the torque converter replaced (unfortunately she did incur an expense), and the next day her d4 light was blinking. Her vehicle is being repaired as I write this complaint. My concern is that the transmission in this vehicle is defective altogether. As I have done a little research, I have discovered that this is fairly common with the Acura Mdx model.

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.

I have a 2005 Acura Mdx premium model. The car is only driven 56,000 miles. There are always a grinding noise when speed is about 25 -- 40 mph. I have been told it is a transmission torque converter problem.

2005 Mdx torque converter replacement @ 55,000 miles, out of pocket cost, $ 3000. 00 grinding noises @ 35 mph.

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.

2005 Acura Mdx. Transmission problem. Seems others on the forums have complained of an intermittent vibration in the car, the diagnosis was the torque converter the other cars. I am having the same experiences these other people have had. ,however since I cant replicate the problem at the dealer no one is doing anything.
