Another round of headlight replacement got done recently (just before the warranty expires), in total, 2x for passenger side and 1x for driver side. So pissed off at this and my dealer says any further occurences of the same thing will NOT be warranted and I will have to take it up with Mazda Canada directly for any approval repair.

I said wtf, this has been an issue from day 1 and you, the dealer and Mazda Canada have known this ongoing issue and yet I was told this would be my problem when the warranty expires. If this is the case, Mazda Canada has just seen my last $ spent on the car ... certainly, I will never buy another Mazda car ever !
