Technical Service Bulletin SSPD5b — 2021 MAZDA MAZDA3

SPECIAL SERVICE PROGRAM - SSPD5 - WARRANTY EXTENSION - MULTI-MODEL - VALVE STEM SEALS CLASS ACTION In conjunction with a Class Action Settlement, Mazda Motor Corporation has decided to conduct an extension of the Engine powertrain warranty related to excessive oil consumption. In addition, there is a Reimbursement Program, for limited qualifying out-of-pocket expenses (prior oil changes and additional oil purchased before the normal oil change interval due to oil consumption concerns) on certain CX-9, CX-5, Mazda6, Mazda3, and CX-30 vehicles equipped with a 2.5L turbocharged engine with the affected valve stem seals. For all Mazda dealers, an FAQ document for this Class Action Settlement and all documents for SSPD5 will be available on Mazda Global Service Support (MGSS) on or before May 13, 2024 concurrent with notification to the Settlement Class. Please review this entire communication in regards to updated coverage for Special Service Program SSPD5 and vehicles out of Powertrain Warranty. Parts & Warranty Information and Dealer FAQ’s on Mazda Global Service Support (MGSS) have been updated. REMINDER! – An oil consumption test is NOT REQUIRED if a customer verbally asks for a valve stem seal replacement and the vehicle otherwise already qualifies for a valve stem seal replacement (e.g., it has the original or defective valve stem seals). If a customer asks for replacement, please proceed with the repair WITHOUT an oil consumption test. An oil consumption test is only required after valve stem seals have already been replaced previously.
