Bought my 2016 Acura MDX in September 2015. Immediately noticed issues with the transmission - jerking, lunging, rigid transition when switching gears. It was the most jerky ride possible for a brand new luxury vehicle. I complained about the transmission every single time I brought the car in for service or other minor issues. The standard response was that is how the 9-speed transmission drives. I brought the car to the dealership at 9,836 miles complaining about the transmission once again. They verified the problem, found a "bulletin" about the problem and did an update through the car's computer system. It didn't help. I continued to complain and in Dec 2017 they verified a problem existed and found a campaign for the ATF warmer and performed another update and replaced the warmer. Transmission still behaved erratically. In Aug 2018 I started hearing a chirping noise around 20 mph coming from the engine. This time they found an internal failure of the transmission and replaced the transmission. The transmission is still jerky and lunges. Worse decision I ever made to purchase this car.

transmission slipping and making a grinding noise

I purchased a 2016 Acura MDX from Jay Wolfe Honda in Kansas City, MO and so far my total overall experience is a "0" I have had my car in the shop for about 20% of the time I have owned it and my last repair was to replace the transmission with 10,000 miles on the vehicle! It still shifts jerky at low speed but I haven't taken the car back because I am going to pursue the lemon law and/or Acura arbitration. I had a loud noise in the rear end, after they replaced the struts (after 3 repair attempts) and it is better. There are 3 Service Bulletins out there for those of you who want to try them TSB No 16-035 replace rear suspension dampers and rear upper mount bushings. TSB No 15-039 Replace transmission end cover gaskets TSB No 15-054 Software update in powertrain and transmission control modules. I called Acura and none of these were linked to my specific vehicle VIN #. Had they replaced the gaskets, I may not have had a fluid leak which supposedly caused the transmission replacement. The module update is supposed to correct the shifting - that is questionable. The rear end work did help the noise in the rear end. I could continue with minor detail issued but suffice to say I WOULD NOT purchase nor would I recommend anyone to purchase an Acura MDX!!
