TPS54231: what kinds of failure mode if EN voltage is 6.2V?

Part Number: TPS54231

Customer found one issue of their mass production design, that the voltage of EN pin is 6.2V during normal operation, which is out of the Absolute Maximum range of 6V.  Actually, they did not need the enable/disable function, but with the wrong resistors presently, they want to understand the risk with 6.2V. If EN pin fails during this condition, what kinds of failure more will be for EN pin? Will it short to GND or open circuit? If the controller can still work normally with EN failed, they don't need to withdraw the present products. 

Highly appreciated with your help here!
