oh wow definitely a failure, they will say something like suspension mounting
area excessively corroded. while your there i would check under the ECU and
fusebox they are common areas for rotting as i have just welded mine recently - but mine was alot worse, had holes on strut mounts and under both ecu and
fusebox

didnt take long though!
heres how mine looked on the strut top :
