No issues with radio in my car.
I think they just want to cut costs and push subscription based media.
Yeah I have AM in my EV as well, though I can't say I've tried it. Plus if the EMF were the actual reason, wouldn't the alternator in ICEs cause similar interference?
you will actually hear junk from the alternator in the AM band if the voltage regulator(s)/rectifier goes bad or a ground gets corroded... the lead acid battery provides a nice smoothing function (almost ideal voltage source) since the alternator and engine have a low impedance bond to the negative terminal (system ground). the low frequency spectral emissions (very low harmonic content) from 1 alternator and associated circuitry is a much simpler problem than all the computers, ac inverters (induced high frequency currents running around everywhere), wiring harnesses, etc. that all act as rf generators/antennas.
