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.

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.

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
