Is the FA24F engine in the 2022+ WRX more reliable than the EJ25 in earlier generations?
The FA24F 2.4L turbocharged boxer is a modern architecture with direct and port injection, integrated balance shafts and improved thermal management compared to the EJ25 it replaced. Early feedback from Canadian owners at 60,000 to 80,000 km is positive — no head gasket seepage characteristic of the EJ, no oil consumption pattern typical of the older block. The FA24F requires 0W-20 full-synthetic oil and a strict 6,000 km change interval. Avoid aggressive driving before 2,000 km on a new example, and on any used post-2022 WRX request documentation of all oil changes from new.
