loud "pop" sound from under the touchpad ( late 2016 MBP 15")

A few minutes right after I lift the lid from the late 2016 MBP 15"(After the machine loads.) I get a loud "pop" sound at random times (maybe 1 to 3 pops) from under the touchpad and then I might not hear it again until I restart the machine again.

I've done the SMC and NVRAM reset and nothing... I still get 1 or 2 from time to time.

It almost seems like the force touch magnet/motor might be misfiring?? any ideas??
