at highway speeds, the transmission unexpectedly shifts to neutral with no warning. The only indication is unexpected decrease in speed and accompanying engine rev. My typical driver response is to take foot off accelerator, then put back on again. Engine overrevs then shifts in to gear. I'd estimate it's out of gear for ~ 5 seconds, but hard to say in the heat of the driving moment. This happens 1-2X most highway trips, but not occur at lower speeds (it does not shift very smoothly in lower gears at times, but it's not currently a safety issue). I've taken it to my local dealer (Hendrick Acura, Durham, NC) and contacted Acura Customer Care, and am trying to get a diagnostic scheduled (it's been a process). The behavior started to worsen over the past several months (e.g. the slip to neutral has lengthened in time) but shorter slips have been occurring for a longer time period.
2017 Acura MDX fuel system complaints

I was on the feeder road of a major freeway in Houston Texas at a stop the brake fully applied. The auto engine idle stop was enabled. When I removed my foot from the brake the engine did not restart. The lights, radio remained on but I was unable to drive my car or change the gear shift. Being on a freeway feeder was a dangerous place to be stalled and had to wait in major traffic for a tow truck to come as the vehicle could not be started or turned off. Completely inoperable. The check engine light was on and oil light. I was towed to a nearby maintenance shop where a p2638 code was listed. After the car was towed the car would restart. Prior to the incident there have been other occasions where the vehicle struggles to restart the engine from the auto idle. However there were no warning lights. Additionally I scheduled service with the dealership the next day and they show an auto idle recall as an item for repair. There is no recall listed on the federal safety agency. Additionally I see a class action lawsuit was filed earlier this week for a potential ongoing, long term issue related to this product.
Fuel pump (High - pressure & low- pressure) failed which has caused significantly reduced acceleration and caused the engine to stall in mid operation of the vehicle. I (Driver) was the only person in the vehicle and there was no crash. I would say there is high risk of a crash and it is a serious safety hazard. There were no warning lamps, messages or other symptoms of the problem prior to the failure.This vehicle component was checked by an independent service center and got it repaired. Fuel pump & high pressure pump was ordered and replaced on the vehicle. I paid $1977.59 as the total cost for parts and labor plus tax.
The car several times now has stopped in traffic and died after the idle stop was initiated while stopped in traffic. It will not start up for at least 30 seconds to a minute. We were almost rear-ended because we were stuck in the middle of the road. I was told that Canada has issued a recall because of this issue
Issues have now occurred twice within an approximately 4 week period. First time was near the end of june and the second time occurred on 7/30/20. After stopping on the highway, once for a stoplight and the other time to turn off highway onto another road, the engine stalled/turned off. After vehicle was back in park, I was able to restart the vehicle each time.
I own a 2017 acura mdx. The VIN is [xxx]. On sunday january 13, 2019 my wife was pulling into our drive way when she noticed smoke coming from under the hood. She got our kids out of the car just before the car burst into flames. It?s amazing no one was hurt. The car, however, is completely destroyed. The fire destroyed our other car in the driveway, the garage door, the gutters, windows, the front door and a large part of the roof. All four tires exploded and flaming pieces of rubber went all over our home and drive way. The car left an oil stain across our entire driveway. The car was still under the one year manufacture end to end warranty. The only service ever performed on the vehicle was done at john eagle acura in katy, texas. We purchased the service package from john eagle acura which cost roughly $300.00 and was a complete waste of money. The car had no warnings and had no indication of a service engine soon notice. The car was reduced to smoking rubble. The car is a pile of broken glass and ashes. Thank you.
Dangerous loss of power while accelerating on the highway! There have been three separate incidences over the last 2 years. While I was trying to accelerate on the highway, the car severely lost power and the "check engine" light started flashing. The car seemed to operate normally after turning off and on the engine. The dealership claimed that there was no computer records of problems after each incidence. Acura just issued a recall of the fuel pump on this model year mdx. However, acura and the local acura dealership refused the repair due to the lack of computer record of failure.
The 2017 acura mdx has an unintended sudden acceleration failure condition. This analysis provides evidence of this issue, and the subsequent communications with acura client relations which ended with a refusal to acknowledge the issue. The purpose of this document is to provide data and evidence in order to influence acura to initiate a root cause analysis; with the objective of implementing a solution for all affected vehicles.
Acura mdx 2017 bought brand new. Has shut off completely 5 times in the last 60days. 3 times in the last 2 days. Come to a stop, entire car shuts off along with electronics. Occured the last three times at an intersection waiting to turn left or at a red light. . Can't move. Have to restart the car. Dangerous. I've taken it to acura and they say nothing is wrong. Service tech told me another mdx owner is having same issue.
