Service campaign C7000
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
This Warranty Field Campaign is being issued to address o-ring replacements at the air compressor coolant lines on certain X15 and X12 engines. This will prevent potential coolant leaks due to non-conforming o-ring material. Through this Campaign, it is authorized to repair applicable components at certified repair locations if all criteria are met in the Action section. This is an update to a previously submitted communication.
