It may be a DC motor, but there is still a lot of switching going on for
it to operate. DC motors don't turn without a switch somewhere. I don't
think there is a car built today that isn't a cluster of switching power
supplies regardless of the base power source.

There's a reason new cars are dropping AM radio for both ICE and EV
power.  Interference is manageable, but at a cost the manufacturers are
unwilling to pay. 

It's also more likely that not that you'll find that installation of any
transmitter voids your warranty.   I'm lucky as my VW allows
transmitters of up to 10W (!)  Don't ask me what I have installed.
You'll also learn if you read the really fine print in the third
appendix twice removed that drilling a hole for an antenna voids the
warranty (looking at you GM.)
