My engine light enabled & my car slowed < 30 mph while driving on a frwy on 2/4/23. I exited & turned the engine off. It was late at night in a rural area, so I waited a bit & turned the car back on. Engine light was no longer on, so I continued to my destination (GA). On 2/5/23, while driving on the frwy, my engine light enabled & my car quickly slowed to < 20 mph. The light stayed on & my car had little power (limped along). After a few hours, there was no change & my car was not drivable. I got a hotel for the night & took my car to the nearest Honda dealer on 2/6/23. The service dept told me my car needed a new engine because the bearing or rod had gone bad (terminology may be slightly off). My car had UNDER 100K miles & I was told it needed a new engine. The Honda serviceman told me he had 3 other vehicles in house with the same issue & he wouldn-??t be able to get to my car for a while. I called the nearest Acura dealer & spoke with a serviceman there, he told me to ask the Honda serviceman to clear engine code & slowly drive the car to the Acura dealership. The Honda serviceman warned me that my car may not make it to the Acura dealership but might if slowly. He cleared the code & I slowly drove to the Acura dealership. I reached the Acura dealership shortly before closing time on 2/6/23, I dropped my car off with the service dept & got a hotel room. I was contacted the following day, 2/7/23, by the Acura serviceman & he confirmed a new engine was required. There-??s now a recall on the same issue my car experienced for same make, model & year, however Acura states my VIN was not affected. It is highly unlikely that my same make, model & year vehicle that experienced the exact issue for the recall is simply coincidence.

First on off glitching when ever accessory mode is used WHILE IN MOTION, FIRST BRAKELIGHT HAD WARNING THEN WARNING ABOUT TRAILER STABILITY ASSIST. WHEN I WENT IN REVERSE, THE WHOLE DASHBOARD INCLUDING THE NAVIGATION SCREEN WENT BLACK AND THE CAR FELT LIKE THE ENGINE STOPPED. THIS HAPPENED A FEW TIMES. I DON'T THINK THE ENGINE ACTUALLY STOPPED THOUGH BECAUSE I DID NOT HAVE TO RESTART THE CAR. THE BRAKE LIGHT ERROR MESSAGE HAS OCCURRED DRIVING FORWARD AS WELL, BUT NOT ACCOMPANIED BY THE BLACKOUT OF THE DASH AND NAV PANEL. Steering becane stiffer ALL OF THIS HAPPENED WHILE IN MOTION.

On a multi-day road trip, the car had a temporary complete loss of power on two separate days. Both times this happened after several hours of driving at highway speeds on I-15 in California, outside temperatures were in the 90s. After a slight deceleration and then applying the accelerator again, there was a 'clunk' like sound possibly from the transmission, and then a complete loss of power. The first time I tried to pull over to the breakdown lane, and then regained power after about 2-3 seconds. The second time, we were in the middle of traffic and were not able to pull over, but again after 2-3 seconds, the power came back. The engine did not rev up when applying the accelerator and there were no dashboard lights. This appeared to be either a transmission, fuel delivery, or engine management/drive by wire issue. While we luckily did not get into an accident, we did slow down significantly on the highway, requiring other drivers around us to break, or change lanes. I have made an appointment with my independent mechanic, but the car has not been inspected yet and I am not able to forcibly reproduce the issue.

This 2016 Acura MDX with the 9 speed automatic transmission and the Auto Engine Shut Off function will sometimes fail to restart the engine after cutting off. This presents a safety issue as the car stalls in traffic. This has happened multiple times over the last 4 years (most recently 06/02/2022). This issue was noted to the Acura service department who stated they could not find an issue.

- Richmond, VA, USA

when air conditioner is running in hot summer days, the car hesitates to restart (sometimes) following idle stop engine shutoff after coming to a full stop at a stop sign or red light. I strongly feel this is a safety concern as this impedes traffic and can causes road rage. If needed I can share video of this situation recurring time to time. Car starts just fine every single time outside of idle stop situations and battery health is near perfect. There are hundreds of forums talking about this exact condition across acura models.

Acura has an open recall that shows the symptoms or malfunctions my vehicle is having for my year, make, and model, but the vehicle I.D number doesn't show this type of recall for it. Now, these things do not add up give the malfunctions I'm experiencing. First and foremost, the car stalls, I could be on the NJ turnpike and as soon as traffic slows down car goes into neutral on its own and engine just shuts off in the middle of traffic, do not know when its going to happen, it just happens. Car then turns on once fully stopped and foot is on break but probably after another hour same thing and it is continuous. I have replaced a number of things and it is still malfunctioning. NHTSA Recall # 19V-060. No check engine light recorded since i bought the car and when running, car runs smoothly. It is preowned vehicle, called Acura and I was told that the fuel pump was replaced, but according to the recall it also needs a software update to fix the malfunction. At this point I just need help on taking the proper steps on getting this safety issue fixed.

Purchased a certified pre-owned 2016 Acura MDX sh-AWD w/ tech a few weeks ago & from day one there have been issues with acceleration off a complete stop like a stop sign, stop light, coming off park or upon putting it into drive. The vehicle will not move when the gas pedal is depressed, will rev high through first, jump into 2 still revving high before finally moving when it hits 3rd. It is a huge safety issue when other traffic is oncoming as you are expecting to "go" & nothing happens when pressing the gas pedal. The dealership inspected the vehicle upon purchase at our request on two occasions but told us it is normal & will adjust to my driving style. This is not normal.they said they updated the software but found nothing wrong with the vehicle. I'm feeling like we paid for a lemon & driving something which is very unsafe especially with children in the car.

My 2016 MDX has a fuel pump failure which has caused my MDX to stall and led to problems with my fuel injectors. There is a recall but my Acura dealer refuses to honor it. On 10/18 my wife was driving the car on the free way and it slowed to a stall. This is a known issue. I have pasted a url to the recall below. The dealer refused to fix my fuel injectors or replace my fuel pump. The are offering a free fuel pump software upgraded but they want me to pay to replace the fuel pump and fuel injectors.

All dash display warning lights will come on sporadically while standing or in motion, last from a few hours to a few days or so, which causes vehicle speed to decrease and certain features to not work. Dealer service unable to resolve problem, but will clear error codes in computer to shut off warning lights.

When slowing down at a yield or a right turn on a green light to about 5-10 mph and then when pushing on the gas pedal there is no acceleration. The car feels like it loses power and then after a second or two, the car will jerk and accelerate very quickly while reving the RPM very high. This has happened on numerous occasions and is extremely dangerous when making a right turn. There have been times where I make the turn and the car does not accelerate and then there are cars behind me that must swerve to avoid me.
