Hello i will help you with your question,
If you are determined to repair this yourself and the vehicle is running properly at this time I would record the freeze frame data if your scanner will let you do that and clear the code. Drive it through several warm, cold cycles and recheck the codes.
I believe your are covered with a 7yr 100k warranty so the dealer should repair it for no cost. If that is the case I would not clear the codes as the dealer tech needs all the information they can get
Please ask if you have questions
Thank you
