Among the 6 model years of Tesla Model 3 in our records for lighting problems, this one ranks #3 by owner-complaint volume.
No new NHTSA lighting complaint has been filed on this vehicle in over 3 years — the issue may be aging out of the active population.
Headlight low beams that are too bright can reduce visibility for oncoming drivers, increasing the risk of a crash.
The manufacturer has issued service bulletins covering lighting on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
On some Model 3 and Model Y vehicles, the Occupant Classification System (OCS) signal might be affected by electrical interference in the seat electrical harness, causing the airbag indicator to display on the touchscreen.

Display brightness issues tie directly to FSD Beta activation. Multiple owners describe the center display switching to AUTO brightness that's too high when FSD engages, forcing them to manually reset it multiple times per drive—a distraction at night especially. The behavior is buggy: sometimes menu adjustments hold in AUTO mode, sometimes the scroll wheel forces it back to AUTO set point. One owner notes this was supposedly fixed in an earlier release but reappeared in build 2023.44.30.14.
Rear tail light failures center on water ingress and condensation buildup in the light housing. Two separate owners report this, with one experiencing complete failure at 4,000 miles after Tesla initially dismissed the condensation as normal. One owner also raises the proximity of the charging port to the tail light as a concern.
Headlight problems include failure of the passenger-side assembly at 22,000 miles and a failure of AUTO mode to turn on headlights during rain and low-light conditions despite windshield wipers activating automatically. Owners also report FSD Beta inconsistencies—turn signal and blind spot video fail to activate when first merging onto highways under FSD control, even though they work for subsequent highway maneuvers. One complaint describes fog lights physically installed but software-locked and unavailable.

When Full Self-Driving Beta is engaged, the center display brightness automatically switches to AUTO mode and increases to a level higher than the driver's previous setting. Drivers report this requires repeated manual adjustment throughout a drive, diverting attention from the road. The behavior is inconsistent: adjusting brightness via menu holds the setting in AUTO mode, but adjustment via scroll wheel may reset to AUTO set point depending on whether driver setting is above or below AUTO set point.
When: Occurs with FSD Beta activation (reported with builds 2023.27.7, 2023.44.30.14)
Symptoms owners cite: Display brightness switches to AUTO when FSD engaged; Screen becomes too bright, particularly at night; Brightness reverts to AUTO set point after manual adjustment via scroll wheel; Inconsistent behavior between menu adjustment and scroll wheel adjustment; Requires driver to divert attention from road to reset brightness
Recalls/TSBs owners mention: Issue documented in NHTSA Complaint ID 11555478 and reportedly remedied in later FSD Beta releases; re-appeared in build 2023.44.30.14
When FSD Beta controls the vehicle on controlled-access highways, the turn signal and blind spot video display activate automatically during lane changes and exits. However, when first merging onto a highway, the turn signal does not activate and blind spot video does not display, requiring manual driver intervention. This appears to be an inconsistency in FSD Beta behavior.
When: Occurs with FSD Beta Version 2023.27.7 on highway entry merge
Symptoms owners cite: Turn signal not activated during initial highway merge under FSD control; Blind spot video not displayed during initial highway merge; Turn signal and blind spot video work correctly for subsequent highway lane changes and exits
Headlights set to AUTO mode fail to activate automatically during rain and low-light conditions despite wipers activating automatically. Driver must manually switch headlights from AUTO to ON via center display menu. The low beam headlamp telltale icon on the display does not show when lights are in AUTO mode during these conditions.
When: Occurred during rain on freeway; possibly related to software updates
Symptoms owners cite: Headlights do not turn on automatically in AUTO mode during rain; Windshield wipers activate automatically but headlights do not; Low beam headlamp telltale icon missing from display; Requires manual menu navigation to switch to ON mode
Water leaks into rear tail light assembly causing persistent condensation buildup. Initially reported condensation was dismissed as normal by Tesla, but eventually led to tail light dimming and functional failure. Reports indicate condensation is a recurring issue in rear light assemblies. One complaint noted proximity of charging port to affected tail light.
When: Failure occurred at 4,000 miles; condensation issue may develop earlier
Symptoms owners cite: Condensation visible inside tail light assembly; Water leakage into tail light housing; Tail light dimming due to condensation; Complete tail light failure; Affects driver's side rear tail light (at least two separate reports)
Repairs/costs cited: Tail light replacement required; pending at service appointment
Passenger side headlight assembly failure reported on 2020 Model 3 at 22,000 miles. Limited detail provided in narrative.
When: 22,000 miles
Symptoms owners cite: Passenger side headlight assembly failed
Fog lights are physically installed on vehicle but locked out via software. Tesla stated fog lights were not part of the purchase and refuses to enable them, despite hardware being present. Owner claims this creates hazard in fog or low-visibility conditions.
When: Ongoing issue since vehicle purchase
Symptoms owners cite: Fog lights installed but non-functional; Unable to enable fog lights through any controls; Software prevents operation of installed hardware
Recalls/TSBs owners mention: Tesla stated fog lights not part of purchase and will not enable via software
Synthesized from 11 NHTSA owner complaints — unverified consumer allegations, summarized for patterns. The verbatim filings appear below.
Recall 21v-00d was registered DEC 2021, notice said waiting for parts. It's been OVER 12 months and no parts yet? Also, the phone number Tesla has listed on the recall notice and their recall info on your website goes to a self-service site that states to use your Tesla app to schedule a repair so there is no way of contacting the company directly to find out about the status of the recall.
Tesla issues an update to software that forces drivers to go through a jumble of menus to do important tasks like turning on defrosters and windshield wipers. These used to be one touch items on the home screen, but now require drivers to take their eyes off the road for a dangerous amount of time.
It's a documented issue but not catastrophic. 11 complaints have been filed. Repairs average $250 and most owners catch it before it causes a breakdown.
Based on the 11 complaints filed, lighting issues most often appear around 4,000 miles. Some report problems earlier; some make it well past 150,000 with no symptoms. Maintenance habits matter — vehicles that received timely fluid services and were not regularly overworked tend to last longer.
Independent shops typically charge around $250 for lighting repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
