2016 Acura MDX fuel/propulsion system problems

“Driving home from a trip June 2019 on the highway at 60mph with 3 children and my husband, my 2016 Acura MDX experienced complete engine failure - alarms started to sound and I experienced a loss of acceleration, lights in the dash included Engine Problem, Transmission Problem, Emission System Problem, Critical Failure Detected Stop Driving When Safe etc. The vehicle shifted into neutral. I was able to pull off the road onto the shoulder. The engine was still running but would not shift into park. I contacted Acura TLC to have the vehicle towed but we were stranded on the side of a very busy highway in 90 degree heat with 3 kids waiting. Not only was it unsafe to be driving 60mph and lose engine power, I had to also negotiate three lanes of traffic to safely reach the shoulder. The dealership that serviced my vehicle stated it needed a "software update" - the vehicle was with them the week before this happened for regular maintenance and they failed to do the supposed software update. I complained about engine issue in this vehicle from the first time I took for service and nothing was ever done about my complaints. I have all my service records from Acura…”

“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.”

“While driving on the highway this vehicle shifted into neutral and lost power. Once pulled to the side of the road, the vehicle was able to be turned off and re started. This happened to my teenage daughter without warning.”

“My vehicle is showing the exact same symptoms that the 2016-2018 MDX fuel pump recall is stating but my VIN number is not part of the vehicles being recalled. I reached out to Acura relations and unfortunately, they cannot provide authorization to repair my fuel pump even though my vehicle falls under the same years that this model is being recalled for. I went to an independent shop to try and understand what the problem with my vehicle is and I was told that the high pressure fuel pump seems to be failing and was asked why I have not taken the vehicle to the dealership for the fuel pump recall. Due to this issue I am unable to properly use my vehicle. If i step on the accelerator too hard, the vehicle gets engine misfires and immediately goes on limp mode.”

““Emissions system problem” warning light has lit up on dashboard twice. This was checked and found to be a faulty code both times however, the second time it occurred, it correlated with the sway bars needing to be replaced.”

“We have a 2016 Acura MDX and it has automatically shifted to Neutral 3 times (twice while driving on the freeway and 1x yesterday while driving on the street at normal speeds) in the last 2 months. On the MDX dashboard, it will display "Emissions System Problem" and then display "Stop Driving When Safe. Transmission Problem. See Manual." However, the car will automatically shift to Neutral within seconds. My children's lives (7 y/o and 5 y/o) were placed in danger as a result of this system failure. I have contacted the Acura Honda Recall Specialists and Client Relations Representatives. The car is being diagnosed at Cerritos Acura dealership at the present time. A case number has been filed since our VIN shows no recall, despite it having recalls for other 2016 Acura MDXs.”
