Had first rain since purchase of Prius v almost got stranded as our Prius would lose power not allowing us to move forward, we were able to reverse and accelerated. While driving at a higher speed than felt safe, and in power mode, allowed us to get to pavement our Prius would still lose power and almost came to stand still several times. As we have to traverse this road daily we are concerned heading into winter. Is this typical? Would different tires help?
Probably both the traction got bad then it lost power, we backed up fine got a running start and along with skidding a lot it would decelerate almost totally stopping again no matter how much gas was given.

Thanks for link to instructions on how to disable traction control. Will try it next time we have wet sand gravel.
