Nissan is conducting a voluntary service campaign to reprogram the Engine Control Module (ECM), and if necessary, the Transmission Control Module (TCM) on certain specific 2013 Nissan Sentra vehicles at no charge to the customer for parts or labor. The reprogramming will prevent a condition in which the vehicle's engine may stop running under certain unique conditions at cold start. The vehicle still meets and exceeds applicable safety standards and there is no unreasonable risk to motor vehicle safety. Campaign ID #: P3212 See this bulletin for further detail.
