Tesla Headlight Recall 26V507: Is Your Model 3 or Model Y Affected?
Too-bright low beams put 20,349 Model 3 and Model Y cars under recall 26V507. Here is who is affected, why no OTA fix works and what 2026.38 changes.
Quick answer
Tesla recall 26V507 covers 20,349 U.S. cars: 18,735 Model Y (2020–2023) and 1,614 Model 3 (2017–2023) built or serviced with Marelli low-beam headlamps that are brighter than federal rules allow in the upper corners of the beam. Software can't fix it, so the remedy is a free service visit. Tesla's latest filing says that remedy is "currently under development."
The new "Dynamic Headlight Leveling" feature in update 2026.38 is a separate thing. It tilts the low beams to cut glare, but it has only reached a small number of Model 3 and Cybertruck vehicles so far, and Tesla and NHTSA have not called it a recall fix. To check your car, enter your VIN on NHTSA's recall lookup or check the Tesla app.
Two headlight stories collided this week. Tesla's 2026.38 update quietly added a feature that re-aims the low beams on the fly, just as owners of older Model 3 and Model Y cars started getting recall letters saying their low beams are too bright.
Put those together and you get the question all over owner threads right now: is my car part of the recall, and does the update fix it? Here's what the official filings actually say, what the new feature does, and what to do while Tesla finishes the remedy.
What owners are saying
Owners on a Cybertruck forum
Several owners called the motor-driven leveling a reasonable stopgap for trucks without matrix headlights, while others argued true matrix lights still do a better job of cutting glare.
Owner on a Cybertruck forum
One owner with an engineering background worried that small motors moving the headlights all the time will eventually wear out, and said they would rather not rely on it.
Owners on a Cybertruck forum
Some owners first assumed this was just auto high beams. Others pointed out the difference: the new feature physically moves the low beams up and down, using adjusters that were already there for service-mode aiming.
What is Tesla headlight recall 26V507?
Tesla filed recall 26V507 with NHTSA on August 4, 2026. According to the Part 573 safety recall report, the low-beam output "exceeds the maximum allowed intensity in the outer upper-right and outer upper-left areas" of a test zone defined in Federal Motor Vehicle Safety Standard No. 108.
In plain terms, the beam is fine where it hits the road. The problem is light spilling up and out toward the edges, where it can reach the eyes of oncoming drivers and people in the cars ahead.
The headlamp assemblies come from supplier Marelli Automotive Lighting. Notebookcheck reports that the limit in that zone is 125 candela, and that measured output reached 230 candela.
Is my Model 3 or Model Y affected by the headlight recall?
Not every older Model 3 or Model Y is included. Tesla picked the specific VINs from its build and service records, so a car can be affected because of the headlamp it was built with or the one it got during a repair.
| Model | Model years | Build dates in the recall | Vehicles |
|---|---|---|---|
| Model Y | Model years: 2020–2023 | Build dates in the recall: Feb 11, 2020 – Dec 24, 2023 | Vehicles: 18,735 |
| Model 3 | Model years: 2017–2023 | Build dates in the recall: Jul 24, 2017 – Dec 2, 2023 | Vehicles: 1,614 |
Here's how to check your car:
- Find your 17-character VIN. It's in the Tesla app, on the touchscreen under Controls > Software, and on your registration.
- Enter it on NHTSA's recall lookup. If 26V507 shows as open, your car is included.
- Watch the Tesla app and your mailbox. Tesla's filings schedule owner letters in phases starting mid-September 2026.
- Not sure, or the VIN doesn't show up yet? Ask through the Tesla app's service section or call Tesla customer support.
Why can't Tesla fix the headlights with a software update?
Tesla fixes most of its recalls over the air, which is why this one surprised people. But brightness in the upper zone comes from how the lamp is built: the light source, the optics and the lens. Software can't change that.
The NHTSA filing lists the remedy as "currently under development" and doesn't name a part yet. Not a Tesla App expects owners will need a service center visit or a Mobile Service appointment. Notebookcheck notes that if Tesla swaps the whole unit, some compliant replacement lamps have the matrix beam function.
The repair costs you nothing. Federal safety recall remedies are free, and Tesla's filing says the affected cars are covered by the new-vehicle or extended service warranty.
Why did NHTSA force a recall?
Tesla had tried to avoid one. Notebookcheck reports that in 2024 Tesla asked NHTSA to rule the noncompliance "inconsequential" to safety. Tesla argued the extra light sits outside the driver's natural line of sight, and it said it knew of no crashes, injuries or complaints linked to the issue.
NHTSA denied that petition on July 17, 2026. The agency said Tesla's testing used ideal conditions, and that rain, snow and fog can make glare worse for other drivers. Tesla filed the recall a few weeks later. It ties back to an earlier headlight recall, 24V208, from March 2024.
What is Tesla Dynamic Headlight Leveling in update 2026.38?
The 2026.38 release notes describe it in one line: "Low beams will automatically adjust their aim based on driving conditions and nearby traffic to maximize your visibility while reducing glare for other road users."
According to Teslarati, the feature uses internal motors to tilt the low-beam projectors. It makes up for changes in the car's pitch from hard acceleration, steep climbs or a heavy load in the trunk, all of which can aim the beam into oncoming traffic. You don't need to change any setting.
So far the rollout is very limited. Not a Tesla App has seen it on some Model 3 and Cybertruck vehicles in the U.S. and the UAE, and Tesla hasn't published a wider schedule.
Does the 2026.38 update fix the headlight recall?
Not as far as anyone can confirm. Autoblog says there's no sign it addresses recall 26V507 and that it shouldn't be treated as a remedy. NHTSA hasn't said otherwise. Re-aiming a beam also doesn't lower its peak intensity, and intensity is the problem the recall describes.
| Feature | What it changes | Who gets it | Recall fix? |
|---|---|---|---|
| Recall 26V507 remedy | What it changes: Hardware fix for over-bright low beams | Who gets it: 20,349 specific VINs | Recall fix?: Yes, once Tesla finalizes it |
| Dynamic Headlight Leveling | What it changes: Tilts low-beam aim up or down as the car's pitch changes | Who gets it: Select Model 3 and Cybertruck so far (2026.38) | Recall fix?: Not confirmed |
| Adaptive (matrix) high beams | What it changes: Dims individual LED segments around other cars | Who gets it: Cars with matrix headlights | Recall fix?: No, high beams only |
What should I do until the remedy is ready?
- Look up your VIN now so you know whether the recall letter applies to you.
- Turn on notifications in the Tesla app. That's usually the first place recall scheduling shows up.
- Don't pay a third-party shop to replace the headlamps for this issue. The recall repair is free at Tesla.
- Check your headlight aim if other drivers keep flashing you. Tesla's service menu has an aiming tool (Controls > Service > Adjust Headlights), but a misaimed beam is a different problem from this recall.
- Carrying heavy cargo or a full trunk tilts the nose up. That raises the beam on any car, with or without automatic leveling.
