A clogged fuel filter restricts fuel flow to the engine, causing starting issues, poor acceleration, engine misfires, and even stalling. Prius owners should replace the fuel filter according to the manufacturer’s schedule, which is typically around every 30,000 to 50,000 miles, o r sooner if symptoms arise.
