The 2007 Acura MDX started having intermittent problems during the latter half of 2016. When stopped at a stop light/sign the transmission disengaged. When accelerating from the stop the engine revved up and the car didn't move. After 30 seconds the car would jerk forward and start to accelerate. The acceleration was slow and when the car reached 30 MPH it would jerk a couple times. This made it difficult to drive in Atlanta because of the traffic. We ended up parking it most of the time instead of driving it. We had the car diagnosed by a couple auto shops and the problem never occurred while they had the vehicle. We brought the car to an Acura dealer and they held on to the car until it the problem occurred. They said the car needed a new transmission/rebuild. The cost is around $5,000. We wrote to Acura and they would not help out. The Acura MDX has been a big disappointment!

My navigation continues to shut down and reboot. Many times when this starts up, my car automatically shifts into neutral when I come to a stop. I can manually shift to neutral and back to drive and this seems to reset the transmission. I have taken my car to the Honda Serivce center multiple times for this problem. They have been unable to diagnose the problem. The first time I took it in, they tried topping off the transmission fluid. Didn't resolve. The second time, they sent me to the Accura Service center. The Accura Service center throught it might be the Nav disc, so I ordered and installed the latest version. Didn't resolve. The third time (I believe) I provided a video of the car acting up and let them keep it for two days so the mechanic could drive it home. They still couldn't figure it out!!! This has been going on for at least a year and a half.
