Automatic parking brake noise

[Julie Montgomery]

My 2017 RX350 has 60,000 miles.  At about 45,000 miles, it started making a noise occasionally when I put the car in park.  I took it in but they could not recreate the noise.  I took it in again for the 55,000 mile scheduled maintenance. That time I had recorded the noise. The service advisor brought a mechanic to listen.  He said it was normal...nothing wrong with it.  It has gotten worse. Has anyone else experienced this?

it might be the automatic parking brake motor.  i also get a short noise when turning off engine.  not sure if it is normal
