We took a test drive locally around the dealer on city streets and drove mostly under 35 miles per hour. Later that day we took delivery of our new 2016 Acura MDX. As we started driving it we experienced problems with shifting. It was abnormal jerking and hesitating at speeds between 10-55mph. It would shift through gears randomly. So much jerking and hesitating that my family complains of jolts to their body. I have taken my car in several times and they insist that this is normal to due 9 speed operation. The only way that I am driving the car smoothly is by babying the pedal. I do not feel safe and do not feel confident in driving it. You would hit the accelerator the car will hesistate before the car goes forward. The buttons while being a cool new feature presents a safety problem because you have to look down and frequently cannot engage in the proper gear. If you need to go fast or ever get chased?? then you can't do so in a quick manner! car now has 9800 miles and this problem still exists.

Transmission failed. This 9 speed transmission has a fluid heater in it that has radiator water supplied to it. Car was not shifting correctly and making a beeping noise at 20 to 25 mph. Car was taken to dealer on 06/11/16 with 8,800 miles on it. They called to tell me that the 2 way valve between the coolant and transmission was faulty and coolant got into the transmission. Acura told them to replace the transmission entirely. Will take 2-3 weeks. Have been having issues the entire time we have had the car. When taking off the car does not accelerate quick, in fact, tends to stall then lurch. Have had issues with the sensors coming on, not sure if this is related to the transmission, but is a continuous issue.

Very similar to NHTSA id number: 10762375. After 3-4 days of driving the check engine light came on along with transmission system U0401, vsa problem, hill start assist problem etc etc etc. The SUV would not speed above 35-40 miles and shake. Dealership replaced cracked spark plug, ignition coil - cause - possible moisture in spark plug. They were nice enough to take the car back and currently waiting for it to be replaced.

On 9/3/15, I was pulling into my garage when all the warning lights on the dashboard went off - transmission, check engine, lane detection light etc. Since I was going out of town the next morning, I put it in reverse and drove directly to the dealer. The car was in "limp mode" and I could only drive 35-40 mph. I showed the tech in the service dept. All the warning lights going off, and he said he had never seen anything like this before. He wrote up a work order with the following info: Inspect for check engine light on, check engine light flashing and every warning light in the vehicle is on, would not accelerate over 35 mph. The following day I was contacted by the service dept. And was told they could not find a problem; there were no lights on, they even drove it for 40 miles. The service dept. Said they are only allowed to hold the car for five days. Today, 9/8/25 I picked up the car. The dealer's invoice reads: Cause: Light on 123505 diagnostic trouble codes/programmed fuel injection (pgm-fi) retrieve codes with the hds, read data, 74 WA3. Inspected for check engine light on, found dtc P0303 (cylinder # 3 misfire) recorded freeze data and cleared codes, at time of inspection vehicle was running perfectly, test drove vehicle twice on extended test drives and engine ran perfectly, no dtcs are reset no problem is present at this time. Since the service dept. Could not find the problem and fix it, this means the car has not been repaired and I am driving a defective car. The next time the warning lights go on, I could be travelling on a crowded freeway at a high rate of speed (with my family inside), the car goes in to "limp mode - 35 mph and an accident occurs. This is a safety issue. How can Acura manufacture a $50,000 car and their dealership not be able to find the problem and repair it?
