I received that email. Letters are mailing out to owners 11/10/24. There is a web site where people can file their claim for reimbursement from Mazda for most out of pocket expenses for a repair
You may be able to get the dealer to make it a CPO when you buy out the lease for a small fee. Esp if you've already put new tires. That will add 1 year/12k miles to the basic warranty and get the powertrain warranty to 7 yrs/100k miles
You probably added way too much from the can. Have you installed a new cabin air filter that is more restrictive than the OEM ones? That can hurt air flow
