I know this is now a very late reply. Have a 22 Corolla se with 61k miles just past the powertrain warranty. Called Toyota manufacturer’s recall dept and while they admit and see that there is a defective valve as stated previously the only CSP is for Rav 4 in response to the class action lawsuit. Which leads me to the next point…. If you’re having this issue with your Corolla or Camry as well, report it to let them know and follow in the footsteps of those before us to get a class action lawsuit in place so they can respond it with appropriately with a CSP!
