Service bulletin S-TT-0109-17

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's 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.
