There are 11 owner-reported fuel system complaints for the 2016 Acura MDXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Hi, Vehicle experienced sudden loss of power and inability to accelerate while driving. Engine entered limp mode and would not rev beyond approximately 2,000 RPM. Vehicle became unsafe to operate in traffic due to lack of acceleration. Dealer diagnosed fault code P0087 (fuel rail/system pressure too low) and confirmed failure of the high-pressure fuel pump. Vehicle had hard starting, delayed throttle response, and multiple warning lights related to engine, emissions, and drivetrain systems. This appears to be a fuel system failure affecting vehicle safety. Acura previously issued fuel-system-related recall(s) for similar vehicles, and this failure occurred despite prior recall-related service. Repair cost is approximately $2,400. Failure resulted in loss of engine power and posed a safety risk, especially when attempting to merge or accelerate in traffic. Vehicle mileage is approximately 160,000 miles.

The vehicle was taken to an independent mechanic; however, the failure was not duplicated. The dealer was made aware of the failure.

The auto engine idle stop on my 2016 Acura MDX has left me in precarious situations at stop signs and/or traffic lights at least twice before the recall notification I received in the mail a couple of weeks ago. The engine turned off as designed but then would not turn back on like it should without a delay. The worst incident was when my teenage Daughters were in the car with me! After receiving the recall notice recently and taking the vehicle into the dealership within days of the notification, my “software update fix” by the dealership (Napleton Acura in West Palm Beach) completely disabled my auto engine idle stop! After calling the service rep I dealt with later that day and telling him about it, I was told the software update made the “turn-off” feature more specific and mine didn’t meet the parameters! My engine was at normal operating temperature, my air conditioner was NOT on and I stopped at at least 12 lights on the way home with no engine stop. That was a week ago and still no engine idle stop has taken place! I’m a pilot and don’t appreciate being talked down to by a supposed “racing champion” named Zeke that feels the need to advertise his prior win on his service uniform! Not only that, but now my safety related “object approaching” notification for front driving and “rear warning” for close objects during parking/reversing are now non-existent! I paid extra for these safety related options and I’m not happy that they’ve been disabled because of the “software update!” How do I become part of the class action lawsuit against Acura/Honda?
My mechanic replaced the battery on May 9th and could smell gas but I had just fueled the vehicle. Two days later is when it got worse while driving back home I pulled over and could smell gasoline inside the vehicle as if an open gas can was sitting in the passenger seat. I stopped using the vehicle and took it to my mechanic and he discovered a crack in the weld on the front fuel rail. This could have harmed my family, pets or myself if it had caught on fire. In 1 hour I used a quarter tank of gas because of the high pressure pushing the gas on to the engine. Vehicle taken to Anchorage Acura and the Acura mechanic confirmed what my mechanic found. There were no warning lights or indications of anything wrong until I could smell the gas.
Stalling when accelerating. Safety hazard because the car basically dies temporarily and slows down. I have to pump the gas pedal for several seconds to get it going again.

WHILE DRIVING, THE MDX SHIFTS INTO NEUTRAL AND CANNOT BE SHIFTED OUT OF NEUTRAL. THIS HAS OCCURRED ON THE HIGHWAY MULTIPLE TIMES. THE INFORMATION DISPLAY SHOWS FIRST EMISSIONS PROBLEM, THEN TRANSMISSION PROBLEM. ACURA HAS A TSB OUT FOR THIS B15-034, BUT WON'T APPLY IT UNTIL THE PROBLEM APPEARS. HAVING YOUR VEHICLE SHIFT INTO NEUTRAL IN A HIGH SPEED ENVIRONMENT IS EXTREMELY DANGEROUS. TSB B15-034 NEEDS TO BE A RECALL BEFORE THEIR MDX SHIFTS INTO NEUTRAL DRIVING ON THE HIGHWAY AND THEY BECOME IMMOBILIZED AND PEOPLE ARE KILLED AS A RESULT....UPDATED 09/22/15 *BF
