Acura MDX Problem Report
Acura MDX Automatic Transmission May Fail
The automatic transmission tends to fail more often than in similar models.
Recently purchased a 2004 MDX and after taking it to the Acura dealership I learned the transmission is bad. Acura has to have been aware of this issue for several years and I am proposing to launch a class-action lawsuit to sue for damages. I would like anyone who has had transmission issues with their Acura to please email me at firstname.lastname@example.org and leave your First initial and last name, current email address, state of residence, year, make, and model MDX. I believe that once we have enough support we generate some interest from high profile law firms. -Devon - devhop18
getting this humming/drone noise whenever the car is in 5th gear. The noise starts around 60mph+ either I'm accelerating or letting off the gas the sound is still there. But when I down shift to 4th the noise goes away. - Visitor
when we pressed on the accelerator it would slip, causing the engine to race up to 5-6k RPMs. The car revs/shudders on and off up there for a few of seconds before finally catching into gear. Now it no longer catches - Visitor
Fantastic design and build quality. However, there is a very severe problem when trying to merge and having to accelerate quickly. The car stalls and acts like you are using the brakes for a few critical and sometimes fearful seconds before it "kicks in" and starts to accelerate as it should before getting hit by the on-coming traffic. I brought it back to the dealer who checked it out and said that it was working fine and that they couldn't find any problems. Well, there is a problem and I think that Acura knows about it, but won't admit to it in fear that it might affect sales. I'll have to tolerate it for now, but no more Acuras for me ever again. - Visitor
transmission failure due yo poor design. They made me pay $1000 - Visitor
Transmission failed at 8500. Gears would not shift resulting in high engine RPM. Dealershp replaced whole transmission and then the PCM (powertrain monitoring computer). I am still experiencing minor transmission issues with the new transmission and car is under diagnostics at the dealership. - Visitor

Or 2004 Acura MDX transmission failed with no warning light or sensor indicators. Reading Honda dealership refused to assist us with the repair, despite my mentioning that this is a well known faulty part. They stated their refusal to assist was because it was out of warranty; and when we had presented the Acura service bulletin stating that this repair is to be done in and out of warranty, they stood firm that they would not assist us because we had not serviced our vehicle at their "stealership" automotive department. Neither reason was valid, but they also would not allow us to take our vehicle to another garage. They also attempted to insist that we needed to replace our motor because the torque converter shudder vibrations had loosened the motor mounts before breaking the radiator hose and resulting in the damage to our transmission. Transmission+radiator+engine+motor mounts totaled $13,000!!! Our Reading Honda dealership receipt stated a warranty repair at $0.00 but we were billed $4900....????? Although the Acura Service Bulletin stated the torque converter / transmission as a known problem to be fixed at the good will of the dealership, they continuously refused.We paid it, in order to get our vehicle back...6 weeks later! Yes, let us know when a class action lawsuit is in effect. We would be more than willing the help. - acuramdxowner
Problem with torque conveter cause the car to shudder at 25-40 MPH. Acura denies that it is a common problem with the MDX. The don't see a problem with multiple failures at 75,000 miles. The want $5,500 to fix the problem. - jrader01
WHILE DRIVING MADE RIGHT TURN, THE ENGINE SHUT OFF, BATTERY WENT DEAD, MDX ACURA 2006. - Visitor
Transmission slipping between 4th and 5th gear - Visitor
Car shift issue engine lite yellow Quoted me 7500 to fix and without further examination just "reporting a failure" - Visitor
My transmission is slipping. I have trouble putting it into gears D5 and Reverse. I'm not mad though because I bought my car from a car auction in February 2013 and it had around 170,000 miles on it. It has ran good without any major maintenance needing to be done. I love my MDX but I can not afford to replace the transmission so I'll just buy another used car. - Visitor
Transmission fails to engage shortly after a cold start. - Visitor
We experienced the same transmission failure and despite a clear Acura Service Bulletin and much additional documentation to support this known faulty part, as well as reference of others who had been to the dealership due to the same transmission failure, we incurred much of the expense ourselves. Contact Acura USA in California with your claim. They will assist in some of the expense but they avoid committing to full responsibility knowing this would cause a full recall of the transmissions. Best Wishes. - Visitor
The transmission makes whining noise with high pitch sound when accelerating. The gear is intermittently slipped when driving on high way (60MPH+) and hesitate when shifting. The 5th gear (Drive mode) was completely out once. I will take it to an auto shop in next few days (appointment). - Visitor
