Official summary
Dealer Message - We have identified a potential concern with GUIDE, AC COMP SEAL 07AAG-5AAA100, which was a part of 6CVC SEAL REPLACEMENT KIT, 07AAC-5AAA1Z0 that was recently sent to all Honda dealers. These tools have the tool number and manufacture date laser marked on a critical surface that may contact the new A/C compressor seal during installation. The added roughness of the laser markings may cause damage to the seal and potentially result in an oil and/or refrigerant leak.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
