YES! I have this same issue currently - Lexus Concord is stating it is a $4600 repair job, and Lexus corporate has stated they will only kick in $1300 toward the repair, which is so lame, as I have been told that only 3rd generation Prius hybrid engines have this issue (of which our car has the same). So Prius and Lexus model years 2011-2016 are affected. Did you go forward with repairs? I am pushing Lexus corporate to pay for more, but it is going nowhere.2012 ct200h with about 132xxx miles on it. Recently the engine started studdering on start up and when accelerating from stop. Took it to south bay Lexus and was quoted at $4500 to fix. Didn't go through with repairs and decided to take my vehicle to car care automotive. Car care informed me that the head gasket is blown. Still waiting for repair estimate. Has anyone had this issue with their ct200h?
P.s. coolant leaked into cylinder 1. Codes P0300 0301 & 0302.
I also found a used engine for $1980 with no issues and have someone who can install it for $900. Thinking that will be my best option, any opinions/advice would be great.
