The vehicle shifted to neutral while driving at 70 mph and the dash started showing transmission and fuel system errors. The vehicle would not shift back to drive mode. After pulling over to the shoulder and turning the vehicle off and on the vehicle could not be put in drive. After about 30 minutes of repeatedly turning off and on the vehicle shifted to drive and was drive able. This could have lead to an accident if there were vehicles behind me.

Acura is refusing to address a serious problem with the engine and power train with the vehicle, this may have already caused accidents on other cars in other states. Please see the historical data which gives a complete audit of the issues I have had. 9/22/18 11 days- vehicle taken to the dealer and dropped for service, punch list of issues since purchase that needed addressed. Alignment report is signed off on 9/24/18, battery check 10/1/18, service was started on 9/29/18, car sat for a week with no service attempt made. Oil stains on roof liner were left there and was told they would not clean them off (later proven to be mechanics grease by merrillville) and spider was my problem not theres per 'rob' in service. Issues the car was taken in for. All of the below service was comleted in 5 miles according to odometer readings. On 10/12/18 I took the vehicle to Acura of merrillville per 'anthony' from Acura client care to have it checked. I drove it with the tech and the tech was able to validate a lot of the issues right away. It was returned to me on 11/2/18 22 days on 11/24/18 I returned the vehicle to Acura of merrillville due to the transmission issue returning, also addressed a couple of issues. Car returned on 11/28/18 4 days vehicle loses power when shifting to accelerate, often have to downshift using paddle shifters to make power or car acts like its going to stall. Brakes do not function unilaterally, hit the brakes heavy while in traffic and the back will begin to come around as though one of them does not grab. Engine loses power when in traffic it struggles to accelerate which could cause a crash if needing power to accelerate onto a expressway from an entrance ramp, or anywhere that requires power to move the car.

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

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.

- Winter Garden, FL, USA

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.

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.

- Allentown, PA, USA

Vehicle making high-pitch chirp after engine is warm. Noticable at idle. Not noticable during driving/cruising speeds. Took vehicle to dealer regarding high-pressure fuel pump tsb. Dealer stated that high-pressure fuel pump was not involved. Stated it may be due to the starter (defective solenoid or drive piston not disengaging). No current tsb exists for starters. Please investigate.

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.

I thought it was the transmission but they replaced the timing belt pulley and it's still making the same chirping sound. The car is very jerky when it shifts gear while driving. Also, the car accelerates when it's going down hill while in motion. Also the drive 1, 2, 3 button is on the steering wheel and when you accidentally hit it, the car abruptly slows down and will not move forward and I had to literally turn off the car and turn it back on while driving in a parking lot and another time while in traffic, had to keep pushing the button because the car would not go but only idle. (city street.) this happened multiple times on different dates. The accelerating while going down hill happens all the time.

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.

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.

- Arcadia, CA, USA

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.

- Lorton, VA, USA

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?
