Tesla taillight and headlight recalls: dark lamps or too-bright beams
Tesla's exterior lighting recalls split between lights that go out and lights that shine too hard. On the dark side: a 2020 Model Y software error that prevented trailer brake lights from illuminating on tow-package cars, and one or both taillights intermittently failing to light on 2023 Model 3 and 2020-2023 Model Y. On the bright side: low beams exceeding maximum light output on 2017-2023 Model 3 and 2020-2023 Model Y, and front parking lights too bright on 2024-2026 Cybertrucks running software before 2025.38.3 — both FMVSS 108 failures that hurt oncoming drivers' vision. The Cybertruck also has a mechanical one: a service-installed off-road light bar bonded with an incorrect surface primer that can loosen and detach.
Warning signs to watch for
- One or both taillights not lighting, often noticed only by drivers behind you or in a reflection at night
- Trailer brake lights that stay dark when a trailer is hitched to a 2020 Model Y
- Oncoming drivers flashing their high beams at you
- A service-installed Cybertruck off-road light bar that feels loose or has shifted on the windshield
Is it safe to keep driving?
None of these five notices tells owners to stop driving or to park outside. The taillight and trailer-light recalls mainly affect how well others can see you, so be extra careful at night and confirm trailer lights work before towing. The two over-bright recalls put the risk on oncoming drivers rather than on you. For the Model 3 and Model Y low-beam recall the remedy is still under development, with owner letters expected October 3, 2026, so you can keep driving while you wait.
What the free repair involves
Trailer brake lights, the intermittent taillights and the Cybertruck's over-bright front parking lights are each corrected by a free over-the-air software update, with no appointment needed. The Cybertruck light bar is a service job: Tesla inspects it and adds a mechanical attachment, or replaces the bar with tape plus an attachment. The Model 3 and Model Y headlight remedy is still being developed. All free.

Common questions
What do I do while the Model 3 and Model Y headlight remedy is still being developed?
Keep driving — the notice sets no restriction. Watch for owner notification letters expected October 3, 2026, and keep your contact details current with Tesla so you hear when the repair becomes available. Nothing you adjust yourself changes the light output.
Can a software update really fix a taillight that won't light?
For this recall, yes: the intermittent failure on 2023 Model 3 and 2020-2023 Model Y is addressed by a free over-the-air update. If a light still stays dark after updating, have Tesla inspect it as a separate problem.
Does the light bar recall apply to every Cybertruck?
No. It covers 2024 Cybertrucks fitted with the service-installed off-road light bar accessory, where an incorrect surface primer was used. Trucks without that accessory are not included, though 2024-2026 Cybertrucks are covered by the front parking light recall.
