Service bulletin TCH-11-004

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

Aftermarket service kits are available to enhance the robustness of the oil return channel in Bendix® electric compressors, particularly for instances where the oil separator cartridge exhibits corrosion. The oil management kits are recommended for preventive maintenance to maintain optimal compressor performance and as a corrective action to help prevent oil-related issues for both the Bendix® ESM2™ (Electric Screw Module 2) and Bendix® EVM1 (Electric Vane Module 1).
