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.
