2005 Acura MDX Owner Comments

problem #6

MDX 6-cyl

  • 135,000 miles


The transmission cooler connection blew out of the radiator, unfortunately there is no oil pressure switch for transmissions so I had no idea that the trans fluid was pouring all over the road. Lucky for me I was just leaving the house and my friend saw it and stopped me. Upon looking at the part -it has only 3 threads and I have found out this is a common thing for MDX and Pilot SUV's. I could have been in an accident due to the transmission failure that has resulted from this failure by others as I have seen on your site example:. ( Pilot ex-L 244hp 3.5L SOHC 24-valve automatic transmission failure).

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".

Engine mounts on the Acura MDX from 2003-2006 seem to fail regularly resulting in excessive torque on the transmission and potential steering input shimming. Honda/Acura is well aware of the early failure of these mounts per referencing tsb 06-014. Further evidenced by numerous inputs of multiple mount failure within a year. This is a significant defect that Honda/Acura should address with either enhanced design or warranty. www.mdxers.org/forums/14-problems/29355-broken-engine-mounts-send-me-your-information.html

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.

: the contact stated while driving 20mph the airbag light illuminated without warning and the engine stalled. The engine would not restart and the battery was discharged. Afterwards, the airbag and tire mounting light illuminated. The vehicle was seen by the dealer and the battery was replaced. The dealer determined the navigation unit was draining the battery. The engine stalling persisted and the vehicle lost all power. The engine was restarted but continued to stall. The vehicle was towed to the dealer who determined there was a short within the airbag SRS module wiring. Although the airbag problem was corrected, the stalling continued. The vehicle was taken to the dealer for further inspection, but the dealer was unable to duplicate the stalling problem.
