Rough gear shift and cars seems to be rev-up at low gears. This can create a dangerous condition while accelerating from stops.

With 1000ish miles on car, while we were driving it shifted into neutral then into park by itself. We were unable to shift the car at all. Fortunately we were at an intersection and not on a freeway. The dealership working with Acura were unable to diagnose the problem. Then it magically worked but they didn't feel we should drive it. Because cause not determined.

I purchased the vehicle on 10/29/15. The car is not driven on a daily basis so there was only a little over 200 miles when my husband noticed a leak while the car was parked on the driveway. When it was taken to the dealer, the technician has confirmed that it was a transmission leak. Gasket and cover will be replaced. The service advisor mentioned to me that there was service bulletin for that problem dated back August. Don't know why the problem wasn't addressed before the car was sold.

I got my 2016 Acura MDX in July. Since then, I am having transmission problems. Off-the-line shifts are erratic, depending on how much throttle I give the engine. Give it 3/4 throttle and acceleration is great, but mileage suffers badly. Give it any less throttle and acceleration is meager, plus the engine revs very high between shifts. One time, I was pulling away from a stoplight after slowing to nearly a full stop (the light just changed as I approached), I pressed 1/2 way on the accelerator and the engine bogged to nearly zero rpms. I thought it died. I let up and pressed down again and it returned to normal. Merging on the highway is also very dangerous and scary. As I hit the gas to accelerate on the on-ramp, the engine hesitates so badly, I nearly run out of ramp. Passing on the highway is the same, unless I press the throttle to the floorboard. Another time, I floored the throttle on the highway while going 50 mph, to pass a car. The transmission down shifted then revved up to 5,000 RPM and stayed there, even after I took my foot off the gas pedal! I had to floor the pedal again to coax the trans to up-shift. I complained to Acura hq. They told me to talk to my dealer. I spoke to my dealer, and they said that's just how the transmission is. So disappointed with car. I suspect bad programming in the transmission on Acura's part. They need to fix this problem before someone dies in a highway traffic accident.

While driving, the MDX shifts into neutral and cannot be shifted out of neutral. This has occurred on the highway multiple times. The information display shows first emissions problem, then transmission problem. Acura has a tsb out for this B15-034, but won't apply it until the problem appears. Having your vehicle shift into neutral in a high speed environment is extremely dangerous. Tsb B15-034 needs to be a recall before their MDX shifts into neutral driving on the highway and they become immobilized and people are killed as a result....updated 09/22/15

The 9 speed zf transmission has unpredictable behavior including: Delayed shifting leading to pauses in power, delayed down shift during attempts at highway speed acceleration, jerky shifts, car remains in neutral when shifting from drive to reverse. Very unsafe condition due to unpredictable effects on speed and car control. This is now a widespread problem affecting the same transmission in Jeep, Chrysler, and Acura models. The Acura tlx has previously been described with this problem. Now the same transmission has been included in the 2016 MDX with the same out come......updated 10/20/15 the consumer stated the transmission was replaced. Updated 12/17/15.
