High-pitched noise
Has anyone else experienced a high-pitched sound when turning that car off that lingers? It usually, but not always happens after leaving the car with alerts of objects within camera range, but even happens when park assist is turned off. It happens all the time and is driving me nuts!

I've owned over two dozen vehicles over the last 30 years including nine Hondas. I first noticed a faint, high-pitched "whine" for a few seconds after key-off coming from the engine bay on a 2016 CR-V then a 2017 Civic then a 2018 Accord and now a 2019 RDX. I suspect it may be coming from either the electronic throttle actuator or the electric power steering motor. Whatever it is, it appears to be normal since I've noticed across multiple Honda/Acura models the last few years.
