Hey Guys:
This article https://www.electro-tech-online.com/custompdfs/2012/01/2011-NASA-GSFC-whisker-failure-app-sensor.pdf seems to be a good read, including the referenced NASA site.
NASA did find a failure mode with the accelerator in Toyota Vehicles due to tin whiskers.
This reference article https://www.electro-tech-online.com/custompdfs/2012/01/2011-kostic-Pb-free.pdf is a very good report on the state of Lead Free and reliability.
Enjoy!
