I'm wondering where you experienced the "fairly severe limp mode" -- our REx can keep up with 75mph driving on a level highway, and will recharge the battery even at 65. Rain and hills have been able to overpower our REx, but never anything that prevented us from maintaining 55mph. Not really limping.

I grant that other climates and situations may have different experiences. We're on the west coast.
