Service bulletin 9004352

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

CAUTION: Denso relay part number 68244159AA can only be used in the Run/Start relay location. Premature relay failure will occur if used in other locations. Other locations require relays which can handle higher duty cycle requirements. Note: Only the Run/Start relay will require replacement for the issue identified in S2108000002 REV B. No other Song Chuan relays should be replaced for this condition.
