Updated Warranty Extension to 7 years/84k miles for entire powertrain on Mazdas with valve stem seals issue

[Tchman2016]

Hot off the presses. For any 2021 vehicle that falls into the special service campaign for the exhaust valve stem seal oil consumption issue, the extended powertrain warranty has been updated to include ANY issue with the powertrain components listed in the owners warranty manual and NOT JUST any issues caused by the faulty valve stem seals and replacement. This includes everything the factory warranty on the powertrain normally covers

The new extension is upgraded to 7 years, 84k miles, up from the standard 5 year 60k miles factory warranty. I have attached documentation from Mazda outlining this. Again, This is only for vehicles that fall into the special service campaign for the valve stem issue.

Also, an oil consumption test is NOT required to have the seals replaced. Do not let them tell you otherwise. It is instructed in the dealer letter to their service dept personnel that it is NOT required and to do the repair if the customer asks.
Hope that helps all.

Haven't seen that document before, but it is also explained in this video from August 2024.

Hey, the video is good but talks only about the issue and remedy. The warranty extension per the class action lawsuit and campaign USED to be an extended powertrain for only issues related to the exhaust valve stem seal fix and not the entire powertrain. Now, it has been updated as of August 2025 to include the ENTIRE powertrain regardless if it had anything to do with the valve stem seals being defective. That is HUGE because it covers everything that is listed in the owners warranty manual for powertrain that is normally covered for 5 years 60k miles but has now been extended to 7 uears 84k miles. The previous extension was JUST for future damaged components related to the faulty valve stem seals which sucked. Now it is everything regardless of reason.

If only all of the Mazda techs were as conscientious as this guy....
