NHTSA Service Bulletin 10203440: 2013-2018 Nissan Altima
Official manufacturer communication context for 2013-2018 Nissan Altima, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Halogen Headlamp Class Action Owner Notification Beginning October 25, 2021, current and former owners and lessees of certain 2013-2018 Altimas will receive a postcard from a Settlement Administrator informing them of the terms of a proposed class action that, subject to final court approval, could extend the warranty on the halogen headlamps. The class action lawsuit alleges that 2013-18 Altima models manufactured with halogen headlamps have a defect that causes the internal reflecting surface to delaminate, resulting in dimming of the low beam headlamps. Nissan denies all allegations of wrongdoing and liability but has agreed to this customer service initiative in order to resolve the dispute. Beginning in December 2018, all genuine Nissan replacement parts were manufactured with a new design. The proposed settlement is still subject to final approval by the court presiding over the class action lawsuit. The court will determine if the settlement will be approved at or shortly after a hearing that is scheduled for December 20, 2021. If approved, the warranty extension will become effective 31 days after the approval is granted. Additional communication will be distributed prior to the warranty extension going into effect. To be clear, unless and until the proposed settlement is approved by the presiding court, there is no warranty extension and you should proceed with halogen headlamp-related claims as outlined below in #3 under what dealers should do. The proposed settlement, and the associated potential warranty extension, include many terms and conditions. Rather than attempting to address questions about the proposed settlement terms from customers, it is strongly recommended that you refer customers to the websites and/or telephone numbers listed below so that they can receive information from appropriate sources and to avoid providing incorrect and/or incomplete information.

Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications.
