My 2017 Acura MDX has many issues with both the transmission and electrical. It has an issue shifting between gears, makes a loud sound like metal on wash board, then loses power for 3-5 seconds. I went to put the car in drive and it would not go in drive recently. I've now had to replace the transmission at 79,006 miles. The electrical system lights up when driving telling me my electronic parking brake has been engaged and also that there is emission system issues. My daughter was terrified and crying since i had a loss of power at the same time my dash lit up and I had to get across 5 lanes of traffic to the shoulder of road. The towing company had to remove battery cable to get my electric parking break to release. This is a dangerous and scary automobile

While driving suddenly all error warnings came up. It included Check Engine Light, Error messages included: Electronic Braking System error, Emission System error. The light indicative of parking P! kept blinking also the (P) came up on the dashboard. Interestingly after some time this all cleared on its own. Then came back again only this time it stayed on. I don't know if this has compromised the safety features of the vehicle including emergency braking (crash avoidance/vehicle proximity)

While driving on normal road with no other cars around, the emergency braking system/forward collision activated and immediately stopped my car with no danger present. This resulted in the car behind me swerve to avoid hitting me in the rear. No warning lights were on the dash or no audible warning either. This seems to be a malfunction in the system.

Incident #2 driving down city street approaching an intersection. No car in front and no car behind. In the middle of the intersection the car auto brakes to a complete stop before releasing back to normal. If a car were behind me I would have most surely been rear ended.

Loses power and unable to accelerate while driving at higher speeds. Has happened 4 times in 2 months

After receiving the vehicle from Acura in March 2020 with approximately 49,500 miles and noticed the vehicle was slipping around 20 to 30 miles per hour. My fiancee drove it as well and felt it slipping in a city stop and go under the same speed. We called Acura to complain about the slipping as well as the battery malfunctioning. They told us to bring it in and we did. The battery end up being dead a few weeks after receiving the vehicle. It was changed. We then were told that the vehicle needs a transmission fluid change and that this maybe causes the problem. We noticed with the vehicle records the fluid was changed at 42,376 miles prior. The transmission fluid ended up being changed and we were told that we would need to drive the vehicle a lot for the slipping to go away. Thousands of miles later the vehicle is still slipping with 53,000 miles. We feel Acura knows the is an issue but doesn't want to fix it. We need help. I'm not the only won having this issue with this particular vehicle when it involves slipping. I have a few documents supporting my case about the transmission fluid and the current issues with the vehicle.

Since owners and on 4 specific occasions. While driving at high speed upon acceleration at 70 mph auto went dead. Lost all power. After eight minutes auto restarted. 9 months ago, while placed into reveres to auto self accelerated T high speed. After brakes applied and vehicle placed into drive vehicle accelerated at a hgh rate of speed. Lock brakes put vehicle into neutral restarted. One month ago while turning left into traffic at a major intersection, car brakes applied awaiting left turn against traffic. Went to accelerate, car dash lights went wild all begin bling rapidly, dash went black, ABS brakes and brake pedal went to floor car went by itself into neutral. Took over 8 minutes to restart. On 9/24.19 Tuesday at 1:41 pm while traveling West bound on interstate 90, at 74 mph while passing a semi truck as I passed the truck, with a clear distance and proceeded to turn into the right driving lane in front of the truck as I pulled right the vehicle dash went black, the ABS and brake peddle went to the floor and the car decelerated rapidly from 74 to 50 mph within a second. The semi locked the brakes to avoid a serious rear end collision. As I reached 50 mph the dash re lite and all instrumentation appear to function and as I pushed down on the accelerator the vehicle regained speed. I can report perhaps 15 to 20 other major items with collision avoidance and electronic dash abnormalities. The vehicle has been in the Acura shop minimally 15 to 20 times over 24 months to no avail. Acura reports software updates or bad battery causing low voltage signals. This vehicle is dangerous and if not addressed will cause death.

While driving, I received the message "advanced driver support system: U3000-49". this is the second time this error has appeared on the console. First time this had occurred was on 9/28/18 and again on 8/13/19. The dealer says I dont drive the car enough and in turn the battery for the camera does not have sufficient charge. Every time I bring this car in for an issue they reset the error message and inform me to let them know to come back if the issue appears. This happened with my trunk and my jerky transmission. On another note, I have had issues with a choppy transmission. The car jerks from 1st to 2nd everytime. They know about the problem but refuse to fix it. The 2019 models dont have this problem as I test drove. It is a safety issue because when you press the accelerator it gives a jerk and in the winter if you are not prepared it can catch you off guard.

I own a 2017 Acura MDX. The VIN is [xxx]. on Sunday January 13, 2019 my wife was pulling into our drive way when she noticed smoke coming from under the hood. She got our kids out of the car just before the car burst into flames. It?S amazing no one was hurt. The car, however, is completely destroyed. The fire destroyed our other car in the driveway, the garage door, the gutters, windows, the front door and a large part of the roof. All four tires exploded and flaming pieces of rubber went all over our home and drive way. The car left an oil stain across our entire driveway. The car was still under the one year manufacture end to end warranty. The only service ever performed on the vehicle was done at john Eagle Acura in katy, Texas. We purchased the service package from john Eagle Acura which cost roughly $300 and was a complete waste of money. The car had no warnings and had no indication of a service engine soon notice. The car was reduced to smoking rubble. The car is a pile of broken glass and ashes. Thank you.

When pulling forward from a stop into a car wash, the zf 9-speed transmission dropped into neutral without warning, causing the vehicle to lose all ability to move forward. When this happened, all warning lights on the dash illuminated, including stability control, airbags, check engine, lane departure, and frontal collision system, and the digital display flashed through every component on the car saying there were system failures in them all. The immediate remedy was to stop, place the vehicle in park and shut off the engine. When re-started the vehicle was able to be driven, but all system failure lights and warning lights on the dash and digital display remained illuminated.

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.

Sudden unexpected breaking of vehicle. The vehicles collision 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. The consumer stated the dealership advised the E-Z pass toll transponder, which is placed at the top of the windshield, caused an interference with the collision avoidance system. The consumer found that difficult to believe.

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.

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.
