Do you subscribe to any Lexus Enform services? If not, I don't believe you will see any impact.

I don't know for certain about your IS, but my LS uses HD radio to obtain the traffic information and is not associated with Enform services / 3G retirement.

 

Cars had navigation before 3G network existed. Point being, no, your car won't be effected, we're just going to lose the Enform app capability.
