Warranty.

My car had accident on the front bumper about an year ago, and My car needed to change to new radiator and condensor. these parts were covered by insurance. My car was fixed @ local bodyshop.( these parts are Nissan OEM parts.)
Last week, I got Service engine soon light on the way home, so i went to dealership to get repair. they scaned my car and found code that was the misfire. they found that my car had accident history and start to telling me my car might not be covered under warranty. and after a few days, i got phone call from dealership and they said still couldn't find what cause of misfire, but It might be ECU. so need to order ECU from japan and take 2weeks. so i asked them if the misfire is caused of the ecu,does it cover under warranty? and they keep said "Don't know". My Q is... if car has accident history does basic warranty will void whatsoever??
