Tesla's 2026.38 update adds Dynamic Headlight Leveling for HW3 cars — partial fix for a 20,349-vehicle NHTSA recall
Tesla began rolling out software update 2026.38 to legacy Hardware 3 (HW3) Model 3 and Model Y cars on September 30, adding a Dynamic Headlight Leveling feature — a partial, over-the-air fix for the low-beam glare issue behind NHTSA's August recall of 20,349 vehicles, but only for cars with matrix LED headlights. Older cars without matrix LEDs aren't fixed by this update and still need a physical repair — the first remedy in two months, but not a complete one.
Tesla began a staged global rollout of software update 2026.38 to legacy Hardware 3 (HW3) Model 3 and Model Y vehicles on September 30. At the time of reporting, less than 1% of the eligible fleet had the update installed.
The update's headline feature is Dynamic Headlight Leveling, which automatically adjusts low-beam aim based on driving conditions and nearby traffic to cut glare for other drivers while preserving visibility. The feature is limited to cars equipped with matrix LED headlights.
It directly addresses NHTSA's recall from this past August. The agency rejected Tesla's argument that the issue was inconsequential and confirmed a recall of 20,349 Model 3 and Model Y vehicles whose low beams exceeded the maximum intensity allowed under Federal Motor Vehicle Safety Standard (FMVSS) No. 108. No concrete remedy had been announced at the time.
The 2026.38 update is the first remedy to arrive, roughly two months after the recall, but it isn't a complete fix. Older cars without matrix LED headlights aren't addressed by this over-the-air update and still require a physical repair.
