Titleist warranty is for 1 year from date of purchase. Keeping the receipt is all that is needed to have dealer get a pickup to be reviewed for defects.
Older than the 1 year or purchased through a secondary market is beyond the warranty. The chances of any relief drop at that point.
All modern drivers will have failure points especially made with multiple materials. The unfortunate effect is drivers can wear out and the owner has to assume responsibility to replace if beyond the warranty period.
