Model 3 does not have the option to install a trailer hitch by Tesla at least not in North America! I tried having an e-trailer hitch installed by my local body shop . Experience was not good as it seems I managed to order the wrong hitch off their web site! Dispute this the shop got the hitch on but with great difficulty. Then my back sensors stopped functioning and lost functions like parking assist. As soon as hitch was removed the sensors worked fine. My shop also verified that the trailer wiring was present so why does Tesla not offer the option as so many of us bicycle and do not want a trunk rack!
My question to E-trailer was how did the web site let me order the wrong hitch but got no good answer. They did say the correct one is the Stealth model but it requires making a hole that I think might void the warranty. Not a good thing .
Wishing there was a Tesla approved solution or an alternative to E-trailer that someone could recommend.
