Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

If this occurs when her knee hit the key area or key itself this can be a fault with the electronic ignition switch ( EIS ).Usually a key wont cause this as when the key fails it prevents it from starting but an internal fault in the electronic ignition switch can cause an issue like this here.

The dealer will check fault codes as this will help them to locate the fault.It is a good idea to tell the dealer exactly how this occurs so they can drive and try to duplicate it to see if this helps them pinpoint the fault but this does sound like the EIS is at fault needing replaced possibly.

If more help is needed, use the reply tab to continue our conversation.
