2005 Acura MDX: Leaving my neighborhood I took a right turn onto the main thoroughfare. After some acceleration (1st gear), I heard a loud squeal/blow. Immediately had no power to maneuver forward and off to side of road in busy traffic. Ironically, MDX was taken for maintenance at dealership. MDX seemingly tested with flying colors 43 days earlier. No cautionary comments from mechanics at dealership.

Hello, I am a very unhappy frustrated 2005 Acura MDX owner. My car 2005acura MDX at 82K miles, I noticed car shifting gear was not shifting smoothly. Having difficulty while shifting gear & which went worse & very stiff. Also, a grinding noise coming, while accelerating at low speeds ( 25-40mph). It started to happen almost every time I accelerate the car or holding this speed on a slight incline level. I have had my mechanic to look at it & was told this noise is a transmission/torque converter problem. It's common to Acura Mdxs. & also, advised to take it to Acura dealer. On Oct-2009 car was placed for service @ authorized Acura dealer. Where dealer state that it's out of company warranty. The gear shift cable as well as transmission was replaced with 3-year warranty Acura dealer at my (owner) expense 5K. Again, in June-2012 @ 89K mileages, same problem started. My car shift gear was not shifting smoothly. My car needed excessive force in order to shift gears. Again, car was taken to an authorized Acura dealer and the gear shift cable was replaced. Dealer state that the gear shift cable was covered with rust. Which I believe the failure was a Acura design flaw. The vehicle was repaired second time at my expense($400) for the same problem or cause. Recently, again (Sept-2012) same strange vibration/grinding noise started. It sounds identical to the issue I was having previously. However, this types of failure recurring every few months later. Unfortunately, I found the same problem still exists. It is very frustrating and feel very nervous while driving with my family. I even get scared to drive this Acura SUV in case it will stop on the middle of the way, while driving. I'm requesting you( NHTSA) to take this serious and possible life threatening matter with Acura and make them accountable and responsible for it.

While driving the SUV in a busy street 30-45mph felt the vibration, grinding, the triangle distress sign came on and felt the vehicle is going to stall. Managed to get the SUV to the parking lot on the right side. The SUV completely stalled there and we got it towed to the Acura dealer. They looked at it and the technician gave us the initial diagnosis as "radiator has blown coolant line, fluids have cross contaminated and will take a lot of time to bleed out, also possible transmission failure in the process would need to retest drive after radiator replacement to see if transmission works".

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.

At low speed and low RPM's up to 35 miles experiencing transmission jitter. Did software update at the dealer ( as per recall), problem re-appeared shortly after. Was advised to replace tranny for $4500. This appears to be well known issue with 2005 MDX's. seeking financial assistance since it is clear design flow.

I have code P0740 which is tcc function. My trans is operating erratically 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 in the 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.

Had trouble with gear shifting very stiff.brought to dealer in 06/11, dealer just greased the cable, brought back in Sept. 2011, told salt from roads caused it and would need new cable. Brought car to another Acura dealer they said cable and lever arm need to be replaced because it was a design flaw the company has since corrected the problem.I had problem a few years earlier but did not think much about it until my wife used my car and had great difficulty and almost had an accident due to the gear shifting. I called Acura (case number [xxx]) jonathan a Acura representative only was giving me approximately $150 off from $450. I told him it was insufficient amount and said I would report it to NHTSA. He said if I did, he would withdraw the offer. He in essence blacked mailed me not to report the problem.

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!!

My 2005 Acura MDX drive train will make a "judder" sound and can be felt in the vehicle all while loosing acceleration at around 30 to 40 mph. The resulting loss of acceleration leads to serious safety concerns while trying to merge into traffic on ramps. There was a recall regarding this problem from Acura. I took the MDX into the dealer and they did a PCM program update. This seemed to fix the problem for about two months but now the problem is back again.

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.

At speeds between 30-50mph when the engine is under a slight load and the rpms are attempting to hold between 1100-1400, there is a loud vibration and shudder. The rpms jitter back and forth jumping by about 100 rpms or so as it tries to hold a steady speed. I had it checked at a local transmission shop and they recommend that I replace the transmission because the problem will just continue to get worse until the transmission completely fails. The problem I'm facing with my 2005 sounds exactly like the problem described in the Acura service bulletin for 03-04 models: WW2.justanswer.com/uploads/thebesthonda/2010-02-04_181956_B06-003.pdf.

Grinding noise on Acura MDX 2005 model. Had the car for two years when problem started. The dealer could never identify the problem. Only when the car was out of warranty did they finally say that the transmission had to be replaced. I am the original owner and my car has 75K plus, but this problem started way before. This repair will cost me at least $5000. I'm sure Honda knew about this problem and decided to ignore it. I feel cheated! Honda must take responsibility for selling faulty cars and not owning up to it. I'm a million percent sure the dealers also knew it and didn't say anything about it. They are negligent as well. I am sure I am not the only one with this complaint.

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.
