VOLUNTARY SAFETY RECALL CAMPAIGN 2020 LEAF; AV CONTROL UNIT
This bulletin has been amended. See AMENDMENT HISTORY on the last page. Discard all previous versions of this bulletin.
CAMPAIGN ID #: PC743
APPLIED VEHICLE: 2020 LEAF (ZE1)
Check Service COMM or Dealer Business Systems (DBS) National Service History to confirm campaign eligibility.
INTRODUCTION
Nissan is conducting this voluntary safety recall campaign on certain specific model year 2020 LEAF vehicles. The AV control unit will be reprogrammed. This service will be performed at no charge to the customer for parts or labor.
IDENTIFICATION NUMBER
Nissan has assigned identification number PC743 to this campaign. This number must appear on all communication and documentation of any nature dealing with this campaign.
DEALER RESPONSIBILITY
It is the dealer’s responsibility to check Service COMM or Dealer Business Systems (DBS) National Service History for the campaign status on each vehicle falling within the range of this voluntary safety recall which for any reason enters the service department. This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in a dealer’s inventory. Federal law requires that new vehicles in dealer inventory which are the subject of a safety recall must be corrected prior to sale. Failure to do so can result in civil penalties by the National Highway Traffic Safety Administration. While federal law applies only to new vehicles, Nissan strongly encourages dealers to correct any used vehicles in their inventory before they are retailed.
