2013-2014 Subaru BRZ FA20 Valve Spring Recall (WTY-84)
A major safety recall affecting 2013-2014 BRZ models where defective valve springs can fracture, causing the engine to stall unexpectedly or suffer catastrophic internal damage.
Last updated: 2026-05-15
What goes wrong
The valve springs in the 2.0L FA20 Boxer engine may fracture while the vehicle is in motion. If a spring breaks, the valve can drop into the combustion chamber, leading to a catastrophic collision between the piston and the valve. This results in immediate engine failure, loss of power, and an increased risk of a crash. Post-recall, many owners reported 'spun rod bearings' due to excessive RTV sealant clogging oil pickups during the re-assembly process.
Symptoms to watch for
- Engine misfiring (P0300-P0304)
- Unusual metallic ticking or knocking from the cylinder head
- Sudden loss of power while driving
- Engine stalling and inability to restart
- Check Engine Light (CEL) illumination
Root cause
Manufacturing defect where the valve springs in the FA20 engine were prone to high-stress fracturing due to design tolerances, leading to potential engine failure or stalling.
Buy time with these
- • Check VIN on NHTSA or Subaru website immediately.
- • If the recall has not been performed, avoid high-RPM driving until the vehicle is serviced.
- • After the repair, monitor for oil leaks or 'knocking' sounds which may indicate technician error during resealing.
Permanent fix
- Replacement of all valve springs with updated, redesigned components featuring higher fatigue resistance.
