When driving around 75 mph on the interstate I went to switch lanes and when pressing the accelerator nothing happened and acceleration was not possible. All warning lights came on, including all wheel drive system problem, emission system problem, all wheel drive system problem, transmission system problem. Check engine and sh-AWD. The power steering and brakes still worked and was extremely lucky to get the car to the shoulder without getting injured or killed. Had car towed to chattanooga Acura dealer. Car was operating normally when they received it. Acura tech support advised dealer to replace transmission and transmission control module (tcm). Also was told Acura is working on a software update for the tcm but it is not available yet but I have little confidence in the fix and little confidence that this won't reoccur. Strongly considering replacing the car

9 speed transmission lurches forward when trying to stop - sending the car forward while trying to brake. Happens when the car should shift between gears 3-2 and 1-2/2-1. Acura dealership said it's the fuel saver once, normal the second time, and updated the tcm/PCM another. There is no one addressing this when it could send my car into another car when trying to stop. The last time I drove it on Sunday 7/15 I was slowing down to turn into a shopping center, going around 20mph when the car jerked forward, snapping my neck forward 12"-14" then back again. The car is at the dealership now with the service adviser saying the lurching is the fuel saver and that Acura won't pay for a warrantied item unless the service light/codes are there.

While driving or parked the "transmission system problem" illuminated on the dashboard. The "D" light also began flashing on console and then car goes into neutral by itself. In addition another warning light came on the dashboard that said "blind spot warning malfunction" followed by 3rd message that said "transmission system problem" and D light disappears from dashboard. When driving, the car continues at same rate speed thankfully. When parked, cannot put vehicle in park and have to use emergency brake. When this happens the car cannot be locked since it recognizes car in drive. Taking to dealership tomorrow. I don't like driving the car since I'm concerned it will go into neutral as I'm driving. I believe this could become a significant safety issue for myself and other drivers at risk. Any time a car does this without explanation on the highway warrants an investigation.

The car overheated and was leaking blue fluid, started smoking and had a weird chirping noise coming from the engine. The car was parked and was jumping another car with a dead battery.

The contact owns a 2016 Acura MDX. While driving 72 mph with the cruise control activated, the vehicle lurched twice and all the warning indicators illuminated, displaying transmission system failure, fuel emission failure, and lane departure failure. The vehicle stalled and was coasted to the side of the road. The contact attempted to restart the vehicle, but was unsuccessful. The vehicle was towed to an Acura dealer (Acura of jackson, 828 adcock St, ridgeland, ms 39157) where it was determined that there was a computer glitch. The computer system was reset. The dealer stated that this was a known failure with Acura and no permanent remedy was unavailable. The dealer also stated that the failure could recur in 10 to 10,000 miles. The contact was concerned that the failure would recur and took the vehicle to david mcdavid Acura of austin (13553 research blvd, austin, tx 78750). The contact informed the dealer that she felt unsafe driving the vehicle and wanted to trade it in for another vehicle. The manufacturer was notified and advised the dealer to attempt to duplicate the failure. The vehicle was currently at the dealer awaiting a new diagnosis and possible repairs. The failure mileage was unknown.

While accelerating and switching lanes on the interstate around 70mph the car reduced power and then downshifted and revved up to over 4K rpms. The car would not accelerate with foot all the way into it and reduced speed to 50mph. Emissions system error, transmission problem error, sh AWD error and blind spot assist error were all illuminated.

In different settings I have experienced a lag or hesitation when I press the accelerator. The hesitation is sufficient that it makes it dangerous to shift lanes at highway speeds as well as to turn left at a stop sign on a local street. I have disengaged the auto-idle feature to minimize the issue at stop signs and I am now driving in sports mode 100% of the time because this minimizes the hesitation; however, it is necessary to "gun" the engine to ensure that the hesitation does not result in a major accident. I have discussed the issue with the Acura service department each time I have brought my car in for an oil change over the past 1.5 years, and they deny that there is an issue with the power train. I do not allow other members of my family to drive my MDX as I fear their inexperience with the transmission problem will result in a major car accident.

While driving on the highway the "transmission system problem" illuminated on the dash board. The "D" light also began flashing. In addition another warning light came on that said "blind spot warning malfunction". the car slowed down. It would not go faster than 15-20 mph on the highway while the RPM's surged to over 4,000 RPM. The car had to be towed to the dealership yesterday. As of today they still have not been able to identify why this happened. I believe this is a significant safety issue that put myself and other drivers at risk. Any time a car does this without explanation on the highway warrants an investigation.

The car rpms do not keep up with the speed. When decelerating in traffic rpms remain high and the car surges forward. Going down hills when taking foot off the brake the car surges forward. When sitting at a stop sign and starting again the car would surge forward. The engine is very erratic and the software updates do not remedy the situation. Very scary driving the car. Cold weather makes the symptoms worse. Need to warm up the car a minimum of five minutes. It is very sluggish in the cold and the surging is more prominent. Not good if you live in cold climates. I need to drive through a residential area of a city with children crossing the street. I am afraid if the car surges when I break there may be an accident with a pedestrian or I may rear end the car in front of me. I have another appointment with the dealer to address the problem. Looking to trade in the vehicle with a different transmission. This vehicle should never be resold!

The transmission on this vehicle is unsafe & the car surges uncontrollably driving downhill. My wife & I can no longer drive this car & our local oakland, ca Acura dealer has not corrected the problem - we have taken it in for correction several times. We have 3 kids so we can't drive around in an unsafe car & dont want someone else driving an unsafe car. Acura recently issued a warranty extension on this issue - this car is leased & we want to turn it in now. Please assist.

I was mailed a letter about a warranty extension for my associated VIN. I definitely have experienced associated issues with my MDX. After calling the Acura dealership on 11/24/17, I was given an appointment for 11/28/17 and I was told they would inspect my car over 2 days and provide a loaner car. My experience was "to say the least" the inverse; extremely disappointing. The service technician took my car for a test drive and told me nothing was wrong. In addition, the service team was extremely unprofessional as once again, the customer was wrong. Please advise about the next steps for service. I am extremely disappointed with Acura unwillingness to listen to the customer. I did take the car for service associated with this issue about a month prior. Overall problem is many times I experience shifting and accelerating hesitation that is jerky. Which indicates a problem with the transmission: This is what the warranty extension states.... the transmission shifts poorly.

We bought a new MDX 2016 and the car was acting very strange.the powertrain was off, 30000 miles engine was out in the middle of the road, noises everywhere. It is in the shop now and it has been 2 months now since repair.it is still in the shop and it has been over 2 months.

As the vehicle is moving at 60 -70 mph and you decelerate or reduce acceleration the RPM goes to zero, car cannot accelerate and you do not control over acceleration in moving traffic. If the car iis coasting and not able to have a stable speed with moving traffic this is can be dangerous. Suddenly, the transmission will engage with a sharp engagement (metal sound) of the transmission after about 6-10 seconds. I complained to the dealer as this has happened several times. They said they could not help me since there was nothing wrong at the time of inspection and they have not heard about this problem. Last week similar situation occurred except the dashboard error lights showed sh-AWD, emissions, transmission problems and rear side warning indicator fault. I had to pull of onto the side of road. Once in park the car would only go into sport mode in first gear. Called Acura roadside assistance and they towed to a local dealer. Next morning they said it was ok. Once they tested via diagnostics they said there were errors in the transmission modulator. Hope this fixes the problem. Car has 36K miles on the odometer. The dealer was very helpful and helped me get temporary transportation to my home city 4 hours away. Other people on the internet are having similar problems that have occured to me. My biggest concern is once the car is out of warrantee this becomes my problem not the manufacturer. What recourse do I have if this a design or quality defect for me and other consumers. Current repairs have being completed and unknown if this problem will occur at future date.

I got in my car this morning an as soon as I put it in reverse, it lurched forward before finally moving backwards (there was no slope). Then, as I approached a traffic light on a city street and applied the brake, the car felt as though it accelerated slightly before slowing down.

Un intended non acceleration. Due to severe lag, delay, and sluggish transmission response. Acura has replaced my transmission under warranty at 11,000 miles and did not admit fault and say there was a problem. Here's more on my experience..in my 1 year of ownership.. to whom it may concern: 2016 Acura MDX 13,000 miles, purchase new from Sierra Acura, alhambra, ca I am writing to request buy back of my vehicle this car is a lemon. Since taking ownership a year ago, my 2016 MDX purchased new has experienced nothing but one problem after problem. Acura replaced transmission a month ago but the problem is still there. Is it engineered and designed to perform in a not safe manner " many times I experience shifting and accelerating hesitation and jerky/jolting. My family and I do not feel safe operating and riding in this vehicle. Several times gas pedal depressed and vehicle lagged at 20 mph for more than 10 seconds before accelerating. A few of the latest new and ongoing problems are below. Driver door now appears off set and at different angle protruding out now. Appears that the door is not closing properly and therefore not sealed at closing. Furthermore every single window has experienced faulty mechanisms with motors, actuators, and seals. When closing the doors it feels like the windows are loose. There are also squeaks and rattles eminating throughout the cabin area. I secured and collected all loose items and the sound is still there. At engine start up each time, there is a high pitch whining noise for a few seconds before engine starts (perhaps something else faulty") I have video / sound documentation of this with 2 seperate recording dates. With regard to the navigation, multimedia unit, it has been lagging, slow (er) to function, and severe delay in backup camera actuating, and audio functions delay in response sometimes.

Hi, I bought a MDX 2016 from autonation Acura last year. I had a problem with the car this week. When I was driving(moving), merging onto a freeway, as the traffic was more, it was slow merge, suddenly I was not able to accelerate as the transmission moved to "neutral" from "drive" automatically. I don't think this is normal behavior and I did not touch the gear buttons or steering wheel shift paddles. This could be a problem with car and its dangerous issue. I was lucky that the traffic was slow moving and I did manage to push to drive again and accelerate. What if this is on a fast moving freeway.

Engine does not start and all the warning lights come up on dashboard. After a few seconds, each of the system comes up as failed. Dashboard shows as acc failed, lane warning failed, emission failed, engine check failed. This is a second failure in last 45 days. First failed on Nov 20 and car was in service till Dec 21. Again the engine failed on Jan 02, not allowing to start at all.

While in transit with just 15000 miles on the car the transmission system problem light illuminated. Car was immediately taken to dealer. This vehicle has a center console push button control for the transmission. The dealer said that there was residue in the controller most likely due to a spilled drink. The controller would need to be replaced and it would not be covered under warranty. To the best of our knowledge we spilled no drinks on the controller. However, what a poor design. The drink holders are right next to the controller! could a spilled drink cause the transmission to lock up based on this design?

There is no way to place the car in neutral without turning the engine on. Today I was at a gas station when a fuel pump malfunctioned and there was a fuel spill that needed to be cleaned. The procedure was to move the car without turning on the engine so they can access the area to clean up the spill. After speaking to my local dealer and to the main contact phone number for Honda North America, there is no way to get the car in neutral without the engine being on. This caused a significant delay in getting my car moved since a tow truck with a dolly was needed.

As I drive my car I experience very strange behavior from my 9 speed transmission. It occurs both while accelerating and decelerating. During deceleration: (1) by only taking your foot off the gas to decelerate creates transmission confusion (the car doesn't know which gear to be in), which can cause the car to lung forward or jerk backward (2) this also makes it hard to stop, requiring lots of extra brake pressure. During acceleration the car can feel unresponsive, which can prove scary when pulling out into traffic.
