My 2019 GT had a massive oil leak last week w/ about ~32k miles and had to be towed to the dealership. I got a call on the next day and they informed me of the cracked cylinder head. I'm still waiting for an ETA on the parts. I also filled out a report with NHTSA. My dealership currently has no loaner so I'm trying to contact mazda for a rental. I'm just hoping they redesigned the repair parts to prevent this from happening again in the near future.
