Is this with your 110v charger that came with the car? I would inspect the plug receptacle in any case. My wires were loose in mine and needed tighten. Was arcing and was melting the rear side of the receptacle from drawing too much current
How can you have loose wires? The charging cable that came with the RAV4P has no loose wires.Can you show us some pictures so I know what you are talking about?My wires were loose in mine and needed tighten.
As you can see I noticed a smoke colored plug first which made me curious so I investigated
So the issue is the power supply from your house and not the cable from Toyota.
