pedropromo60,
More food for thought. The human body model is about 1500 Ohms resistance which limits the discharge rate of a large charged object (AKA vehicle). Any object that is isolated from earth by for example tires can easily build up a large static charge under the right conditions. The resistance of the body can make a discharge feel like and affect the body as though a continuous currrent was flowing even though it was a discharge limited by the impedance of a body and the stored charge. Believe me, I've been hit by 350Vdc with one hand in my pocket (this prevents the current from going through the heart and causing defib) and it put me out of comimssion for several minutes

...won't do that again! You may want to consider a ground strap that connects to the vehicle and drops to the ground when stopped to discharge the vehicle as some locals are more prone to static charge build up.
It is very very remote that there was a complete circuit between the HV battery, earth ground and the vehicle and your Daughter, however there is a very remote possibility that something could be going wrong that could cause this to happen so make sure due diligence is done by Ford engineering.
Sincerely, Don
