Nissan North America has informed the National Highway Traffic Safety Administration (NHTSA) of its intention to call back certain Infiniti M35 Hybrids to address issues with unexpected engine shutdowns.

The decision follows the company’s investigation into several field reports, earlier this year, the first of which came from foreign markets, and deep into the probe, the automaker uncovered a single incident in the United States.

In the affected vehicles, which have been manufactured from March 23, 2010, to September 9, 2013, at the Tochigi plant, in Japan, the hybrid cooling system can malfunction due to certain conditions. Informing the driver of the problem will be a warning light on the instrument cluster, but if this is ignored and the car continues to be operated for a long period of time, then the hybrid powertrain control module will shut down the engine, as it is programmed to do, in order to prevent damage.

Nissan will start notifying owners of the 1,140 potentially affected units by US mail in August and dealers will reprogram the hybrid control module, automatic transmission control unit and inverter software free of charge. The recall will kick off on September 6. In the meantime, the NHTSA reminds retailers that it is illegal to sell or deliver vehicles in their inventory that suffer from this condition until the campaign action is performed.
