Tesla Recalls Over 20,000 Model 3/Y Vehicles Due to Excessive Low-Beam Headlight Brightness

Recently, the U.S. National Highway Traffic Safety Administration (NHTSA) disclosed that Tesla has initiated a proactive recall affecting 20,349 vehicles, covering certain Model 3 and Model Y models. The recall stems from low-beam headlight brightness exceeding federal safety standards — real-world measurements reached as high as 230.1 candela (cd), while the regulatory limit is only 125 cd.

This recall covers 18,735 Model Y vehicles built between 2020 and 2023, plus 1,614 Model 3 vehicles built between 2017 and 2023. The defective component is the headlight assembly supplied by Magneti Marelli, with part numbers 1077371-98-L and 1077372-00-L. These assemblies were primarily installed on vehicles produced before June 2, 2023; an additional 432 vehicles produced between June 2, 2023 and May 3, 2024 also slipped through quality control and carry the same noncompliant headlights.

Notably, this issue is not new. As early as 2023, a certified Canadian laboratory identified during routine testing that the relevant headlights failed to meet standards. Tesla subsequently conducted internal verification and confirmed the findings. At that time, Tesla filed a petition with NHTSA seeking approval for a limited, partial recall — citing 'no reports of accidents or injuries' as grounds for exemption. However, NHTSA formally denied the petition in July 2024, mandating a full-scale recall.

Unlike many previous Tesla recalls resolved remotely via over-the-air (OTA) software updates — such as million-vehicle campaigns addressing brake chime alerts or camera calibration — this recall notice **explicitly states no software adjustment can correct the brightness issue**. Given Tesla's earlier efforts to seek exemption, industry analysts conclude the excessive brightness results from a hardware-level optical design flaw — one that cannot be remedied by tuning LED drive current or control logic, and thus requires full headlight assembly replacement.

Tesla has already notified all authorized U.S. sales and service centers to procure replacement parts and prepare workstations. Affected owners will receive paper recall notices by September 15, 2024, and may then schedule free replacement service per instructions provided.
