Why do my Arabica beans smell and taste of burnt rubber? I recently bought some Kenyan SL28, SL34 beans with a supposed blackcurrant note. It has an overwhelming burnt rubber flavor that I thought was exclusive to Robusta, how come?
First thing to keep in mind is that taste varies from person, so you may try other beans/brews that have similar descriptions, so you can learn about your own taste perception.

That been said, would be nice to know your equipment, in order to help you more. If you are using an espresso machine, maybe is time to have it cleaned. Mine was dirty a while ago and any beans would taste like burnt rubber, even light roasted ones. If you are using some infusion method (inverted aeropress or french press), try reducing the brewing time.
