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 bulletin announces availability of a new CVT electric oil pump developed to address DTC P173B: ELECTRIC FLUID PUMP \(CVT\) PERFORMANCE. The related customer concern describes the Auto Start Stop warning lamp flashing and the system becoming inoperative under certain circumstances. When Auto Start/Stop is inoperative, the vehicle operates like a traditional vehicle not equipped with this feature. The new pumps contain revised judgement logic to eliminate false illumination of the warning lamp.
