driverside door wont lock , headlight condensation, DTC symbol on dash

my driver side door will not lock????
and my headlight assemblies, driver and passenger side, have constant condensation due to deterioration of rubber seals on headlight assembly, seems to damage headlight control module. Everyone seems to have this issue , is it a recall? will dealer fix free of charge???
and my DTC symbol is appearing on dash(orange triangle with ! ) . this also seems like a common problem with this model.. is this also a recall issue? .. should be!! HELP!!!!
