# Service bulletins for the 2021 Nissan Sentra

VOLUNTARY SAFETY RECALL CAMPAIGN 2020\-2022 SENTRA; INNER TIE ROD INTRODUCTION Nissan is conducting this voluntary safety recall campaign on certain specific model year 2020\-2022 Sentra vehicles to replace both inner tie rods. This service will be performed at no charge to the customer for parts or labor. IDENTIFICATION NUMBER Nissan has assigned identification number R23B3 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.
