I know that other model year RAV4s (and several other makes and models of cars) have been know to exhibit a click from the wiper relay only when the wipers are set to intermittent mode. I've had my RAV4 Hybrid for about two months now, and today is the first time I noticed the relay click. Wow is it annoying! Just checking in to see if anyone else with a RAV4 Hybrid has noticed the same issue. You'd think for as much as we pay for these vehicles that there would be some sound dampening measures in place for the relay.
