general problems of the 2017 Acura MDX - part 2

Sudden unexpected breaking of vehicle. The vehicles collission avoidance system kicked in and breaked from 30 mph to a complete stop for no reason. There was no vehicle or object in front of my vehicle. Clear dry day. Traveling on a 4 lane local roadway.

Acura Mdx 2017 bought brand new. Has shut off completely 5 times in the last 60days. 3 times in the last 2 days. Come to a stop, entire car shuts off along with electronics. Occured the last three times at an intersection waiting to turn left or at a red light. . Can't move. Have to restart the car. Dangerous. I've taken it to Acura and they say nothing is wrong. Service tech told me another Mdx owner is having same issue.

Hi, I have a 2017 Acura Mdx. My transmission shifts to neutral unexpectedly. It happens when I'm driving. Most of the time it shifts back to drive. Therefore, it never bothered me, it happened since I bough the car. It didn't happen often so I didn't think anything of it. However, lately it started to happen more often. Now when it shifts to neutral it doesn't want to shift back do drive. My concern happened when I was on a highway driving in a middle lane. I had to pull over and when it shifts to neutral. When it shifts to neutral you can't add gas and the vehicle starts slowing down. I received warning on my dashboard ((p))! - electric parking brake problem and (transition picture)- emission system problem came on. I turned the car off and then on. After, I turned on and press d or r the car doesn't want to go forward or reverse. I have to turn the car off for about 15 min and then when I turn the car on and press drive it drives without a problem. Recently, it started to happen more often. I happened to me today. I was on 2 line road on a left lane. My car stated to slow down. I was lucky nobody was on right lane, so I was able to change lanes and then I had to pull over and turn the car off. I waited 5 min turned the car on and it drove. I'm scared that I might not be as lucky as I was and get in an accident when the transmission shifts to neutral. My VIN is not on recall but there is a recall on 2016-2020 Acura Mdx with same problem. 16v640/kc2 recall. I already contacted my dealer with no luck. They told me to contact Acura. I made a case # [xxx] with Acura. I was told they can't do anything and the bounce the ball again this time to NHTSA. Here I'm looking for help. My dealer found a par 573 safety recall report on NHTSA site. I love the car. I was hoping you can help me with this problem or maybe you can tell me who can help me. Thank you, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was parallel parking my car and after I got the car in the space warning lights starting coming on the dashboard. The warning lights were; electric parking brake problem, emissions system problem, blind spot info system problem, tire pressure monitoring problem, transmission system problem. I tried to put it into park and it would not engage. Then I thought maybe if I drive it forward some and then park again it will reset. I drive out of the space and noticed there was a red flashing light that read park and the d was flashing. I think the car was telling me I needed to park the vehicle? I went ahead and parked again put it in park (it worked this time, but the p was flashing) and then turn off the vehicle. It would not turn off and instead it just beeped when I pressed the ignition button. After what felt like forever I decided to press and hold the ignition button. It finally turned off. The next day I went to move the car, again all the same lights came on but this time it would not let me put it in reverse. I put the vehicle in reverse took my foot off the break pedal and nothing happened. I put it in park and again tried to put it in reverse. Nothing happened again. I thought maybe the brake was engaged, so I tried to release the brake and tried to reverse again. Nothing happened! I even pressed the gas pedal thinking it was maybe in between gears, nothing happened. I tried putting it in park and then reverse several times before the car finally reversed. I've only had the vehicle 1. 5 weeks I bought it brand new with 26 miles on the odometer. Also, I noticed both of the display screens do not turn on immediately like they used to. When I turned on the car it was a full minute before they turned on and the ac turned on.

We have experienced many issues with our 2017 Mdx sh-awd. On a cold start when shifting from first to second gear there is a sudden lurch hard shift. Once warm this is still present but not as pronounced. The transmission seems to slip through gears and have sudden downshifts that decelerate the car or the vehicle will lurch forward without having your foot on the gas as it shifts itself into a different gear. When trying to 'punch it' and accelerate quickly it will often hesitate to go into the correct gear then suddenly rev high as it speeds up. Hunting up and down through gears while staying at a constant speed. The navigation system is extremely slow to come up and respond to inputs when the car is started. Acura has claimed this is due to cell phone bluetooth interference. Collision mitigation system has engaged twice. The first time by husband was in a parkinglot driving through a row looking for a spot to park. The car slammed on the breaks with no cars in his path and nearly caused the car behind him to rear end him. The second time I was approaching a stop light to turn right, there was a vehichle in front of me but the distance I was stoping from the rear of that vehichle was not an abnormal or alarming distance. The brakes locked up with lights flashing on the dash and an awful grinding noise coming from beneath the car. On one occasion from a parked position it would not allow us to engage it in drive. It flashed "shift to park" on the dash. It took three attempts to get it to go in to drive. The rear hatch hydrolics had to be replaced within the first 6 months as the power liftgate stopped working. One of the two key fobs also went out on us in the first 6 months, replacing the battery did nothing and the whole fob needed to be replaced.

Since christmas, the vehicle has had 8-10 occurrences in which the electrical system is going haywire. The instrument panel lists errors and code failures. And the vehicle cannot even be shut off. There is no cruise control when this occurs, and many of the 'add' on safety components (lane assist/etc) do not work. We stopped by the dealer last month, and they couldn't find any stored codes. Yesterday after my wife drove 6 hours home from detroit, with no cruise control and the issues occurring, she stopped back at the dealer. They took it in, as they believe there is a short in the abs system. They provided a loaner as they rectify the problem. Issues began around 2500 mile mark for mileage. Veh has 4500 miles on it currently.
