This is a supplemental report to document a severe, recurring safety hazard involving an uncommanded loss of motive power and delayed acceleration from a complete stop. The vehicle is a 2018 Acura RDX with approximately 75,000 miles. The automatic transmission 4th clutch fluid pressure switch (diagnostic trouble code P0873) has failed twice in less than a six-month period. The switch was initially replaced in early July using a brand-new OEM dealership part. The vehicle had also previously undergone a full transmission fluid flush. Despite verified wiring and clean fluid, the replacement OEM component has prematurely degraded and failed yet again under identical driving conditions. The…

The light comes on due to an emission system warning, shaking, and a lack of power; the engine is severely misfiring. This is the second time I have complained about this to the NHTSA

The transmission went into limp mode one day after coming to a stop. When I safely got home, I turned the car off. Upon restarting, the issue was gone, but this has now happened several times. Each time, putting the car into park, shutting it off, and restarting it "resets" whatever was going on. Eventually the CE light came on, got the code, and it came back as P0873. The CE light was off after once again shutting the engine off and then restarting. I've purchased the necessary materials to complete the repair, but I've read on many forums this is a common issue, with some even reporting it recurring even after replacing the pressure switch. Acura should issue a recall and absolve all…
