What drivers notice on this 2016 Toyota Scion Fr-S

Owners of the 2016 Scion Fr-S often report a distinct pattern when this stalling occurs. It's typically not a sudden, high-speed shutdown but rather a loss of power as the vehicle decelerates. You might be approaching a stop sign, pressing the clutch in (for manual transmissions), or shifting to neutral, and the engine RPMs drop too low, causing the engine to sputter and die. This can manifest as a subtle shudder before the engine cuts out completely, or a more abrupt cessation of power. Sometimes, the car will restart immediately with no further issues for a while, while other times, it may crank but struggle to catch, requiring several attempts. This issue can be intermittent, making it particularly challenging to diagnose as it might not always happen during a mechanic's test drive.
