    Another symptom was smelling sulfur in the cabin. The issue happened on/off for several months before we took it to Toyota. The issue turned out to be an EGR valve. This is covered as part of a recall by Toyota, so take it to your local Toyota dealer and they should fix the issue for free!

    Welcome to Prius Chat (y).

    Since you are recommending something, can you provide some background:

    • Miles on your Prius?
    • When did you notice the issue?
    • Did it display a dash light ?
    • Did you have to pay a diagnostic fee?
    • Is the only thing they did was to replace the egr valve?
    • Did they replace the egr cooler?
    • If not, have you considered cleaning that?
    • Does your Prius consume any oil?
    Those are just some questions ;).

    Look forward to additional details from your experience (y).
