I wound submit a warranty claim through Taylormade. On the website, they disclaim a 2 year window from purchase date, but I can attest that I just went through the same thing with my M6. Cracked the face and noticed when I was just hitting balls on the range. Taylormade got back to me within a day of submitting the warranty claim and replaced it with a SIM 2 (free upgrade) despite being outside of the 2 year warranty mark with no questions asked.
