   While driving, the vehicle experienced a sudden internal mechanical and electronic transmission failure. Without warning, the vehicle shifted itself directly into Park while navigating the busy intersection of [XXX] and [XXX]. This caused a complete loss of propulsion and left the vehicle entirely immobilized in the middle of a high-speed junction. The vehicle could not be moved, creating an immediate, severe highway safety hazard that required an emergency 911 police…

   While driving at highway speed, the vehicle suddenly lost the ability to accelerate. Immediately prior to this, the vehicle was making an abnormal engine noise, which continued until the failure. "Drive" light turned off and the "Neutral" turned on its own. I tried to get it to shift back to "Drive" and it wouldn't. I pulled off to the side of the highway. The engine stalled and the vehicle would not restart. The vehicle was towed from the highway and we were told to have it…

   The transfer case is blown, with metal debris collected in it. This has caused the all wheel drive to not work because the transfer case is not sending any power to the rear wheels. The car dashboard doesn't register that that transfer case isn't working, so it it thinks the all wheel drive is working, when it isn't. A bad transfer case can cause the car to lose control or traction when it needs to use the all wheel drive system or completely stop while on a highway because…

   I was driving at about 65mph on the NJ Turnpike at 7:45pm on 8/28/25 when suddenly the accelerator pedal was non-responsive over a period of about 3-5 seconds. The RPMs dropped (engine did not stall) and the vehicle speed began to diminish. No warning lights showed and the dashboard remained lit as usual. The road was wet from a recent downpour. This was a very scary moment as my vehicle was surrounded by trucks. I further depressed the accelerator pedal and was able to…

   My 2019 Acura MDX which was owned for less than two years, broke down due to a transmission failure. The vehicle had an open recall (one of many recent) delayed by Acura for months, which research shows can cause engine and transmission damage. Acura of Reno denied the recall link and misattributed the failure to “incorrect fluid,” despite admitting the fluid was correct to myself and other businesses. I believe this breakdown was directly related to the open recall and…

   At only 44,318 miles, my 2019 Acura MDX began showing clear transmission problems in the lower gears — including delayed acceleration, gear slipping, and jerky movement when starting or turning at low speed. These symptoms posed an immediate safety risk, especially when merging into traffic or making turns across oncoming vehicles. I first brought the car to Oakland Acura, which incorrectly diagnosed it as a transfer case issue. Their misdiagnosis delayed the repair process…

   Rear differential SWD light came on was told it was my tires but in fact it is water corrosion in the rear differential oil pump and subframe wiring harness. Acura is aware of the issue but will not warranty the work. This should be a recall

    In front of the red light on the way to work in a morning, I stopped my MDX, then when the red light changed to green, I pressed gas pedal to cross over the street, but unfortunately, my car was pulled backward, and meanwhile, I heard a loud sound of Bang from my mdx. I suspect that the loud sound must be from the gears conflicting in the transmission when automatic transmission shifts. Moreover, the car jerks at around 45 mph speed sometimes. Acura must recall fixing this…
