Official summary
TT: During previous air conditioning service, leakage prevention agent (A/C stop leak) may have been added to the A/C system. Adding stop leak products to the A/C system is not a recommended or approved Scion repair process. During A/C service, moisture enters the A/C system, and can react with the previously added A/C stop leak, forming a gelatinous substance. The gel substance that forms can cause the A/C compressor to bind and or seize.

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.
