Cooling system and CARB warranty

no one? i guess you can check the warranty book.

 

It is hard to know how to reply. You list a 2012 Prius, but posts in a Gen 2 forum.
Massachusetts has been CARB since 2004, so all of Gen 2 would be covered.
I can post the warranty of 2012 but I doubt it is the relevant one.

Page 27 of the PDF, page 25 of the manual. But I bet it is the wrong manual, I just do not know what year IS correct. (None of your items are covered in 2012, but then a 2012 Prius contains none of those parts)

 

Speaking from experience, most of the parts you listed should be covered, as they would definitely trigger a CEL, meaning emission(s) issue. And a CEL will absolutely produce a failed emission test (if the car needed to be smoged).

Jan 2014, 122K miles, DTC P1121 (3-way coolant control valve). Take the car to the dealer ship telling the service writer about the DTC, and suggesting that this should be covered under the CARB warranty b/c emissions related. A Technician assessed the car. A few hours later, pick-up the car after warranty work was performed.

However, I have heard people in California having to pay out of pocket for the 3-way coolant control valve, and they were no way near 10Year/150K miles. Guess their service writer doesn't know what is covered, doesn't want to push for warranty coverage, and/or the vehicle owner doesn't want to fight for this.
