Hi there I have a 2014 i3 with REX. And I never have had a problem before today. No error message no nothing battery slowly went down to 3.5 % and Rex didn't kick in.

I was going down to the interstate and luckily by rest area. Pull off road and eat send the hatchback got back in hit power button put foot on accelerator pumped brakes 3x hit start and REX turned right on and in 20 minutes charged back up some.

My question is REX works or would not have turn d on in emissions mode. What could be preventing it from turning on driving.

Has anyone had this problem before. Also no Check Engine light came on no warning of REX power failure.

Anyone and any information would be welcome.

Thanks
