Tesla Model 3 headlights problems

Filed Aug 31, 2026 · Driver assistance, Electrical · CO

My 2022 Tesla Model 3 Long Range has developed a failure of the Autopilot/ADAS computer. The AP computer remains installed in the vehicle and is available for inspection. The vehicle operated normally before software update 2026.26.6. Following the update, Driving Visualization and Autopilot began going offline, along with automatic headlights, automatic turn signals, emergency braking, collision and traffic warnings. The failures have continued despite software/firmware reinstall, DAS reset, camera calibration, and hard reset. Tesla Service inspected the vehicle and confirmed that the AP computer is defective and recommended replacement at approximately $2,600. I paid $120 for Tesla's diagnostic assessment. Service Mode has recorded repeated AP watchdog/kernel-panic events, including APS_w169_TurboA_SCS_LKUP, APS_w134_appMIA, APS_w135_appCritical, and PM_a041_dasMIA. The vehicle has also recorded simultaneous exits of multiple camera streams, sometimes causing camera feeds to go black while driving. Service Mode has shown the AP ECU in Coreboot/INIT, intermittent loss of communication between the AP ECU and infotainment ECU, missing GNSS Ethernet communication, and unavailable AP temperature telemetry. This creates a safety concern because multiple safety-related driver-assistance and camera-dependent systems can unexpectedly become unavailable while driving. The vehicle remains manually drivable, but the driver must unexpectedly operate without previously available functions. The failure can also affect automatic headlights and turn signals, requiring manual operation. I am reporting this as a potential safety defect because multiple ADAS/camera systems fail simultaneously and the AP computer repeatedly crashes/reboots. The failure began after a software update, although Tesla has stated that some alerts predated the update. Due to the GPS board contacting the autopilot first before the infotainment, precise location is off and navigation is unavailable.

Incident / Safety Defect Summary: A certified Tesla mobile service technician improperly calibrated the low-beam headlights on my 2018 Tesla Model 3, causing a severe reduction in forward night visibility and creating an immediate roadway crash hazard in direct violation of FMVSS 108 illumination standards. Detailed Description of the Safety Failure: Improper Calibration Environment: The technician attempted to perform the headlight alignment procedure inside a closed residential garage with approximately 12 inches of clearance between the front bumper and the garage door. Standard automotive and manufacturer procedures require either a level 25-foot standoff from an aiming target or a dedicated optical aiming tool. At 12 inches, optical beam geometry and cutoff steps cannot be evaluated. Extreme Downward Misadjustment: The technician bypassed standard cutoff alignment and manually adjusted both headlights down to their absolute lowest mechanical limit using the vehicle interface. Safety Impact: The usable beam throw is now restricted to only a few feet in front of the vehicle's bumper. At standard driving speeds, especially during early morning and nighttime commutes, the vehicle completely overdrives the low beams, rendering road hazards, lane markings, and pedestrians invisible until impact is imminent. Manufacturer Failure to Triage Safety Rework: When reported to Tesla Service as an urgent safety-critical failure caused directly by their technician, the service center refused immediate safety triage/rework and scheduled resolution days out, leaving an unsafe vehicle in service.

The vehicle is experiencing severe, unpredictable software and hardware regressions related to the Full Self-Driving (Supervised) system (v14.3.7, Software build 2026.21.5) that create an immediate, active traffic hazard and a high risk of rear-end collisions. Primary Safety Issues: 1. TRAFFIC STALLS UPON DISENGAGEMENT: When Full Self-Driving (FSD) is engaged, auxiliary sensors malfunction, causing the headlights to cycle on/off and windshield wipers to run at full speed in clear, dry, midday daylight. When attempting to manually disengage FSD to correct these malfunctioning systems, the vehicle fails to smoothly transition control. Instead, it triggers critical red flashing alert lights, sounds severe warning chimes, and initiates an immediate, aggressive brake application—stopping the vehicle dead in active, live traffic. 2. PHANTOM BRAKING: The vehicle routinely experiences sudden, severe, and unprovoked phantom braking events while driving at speed, without any forward obstacles or environmental hazards present. 3. STEERING INSTABILITY: When navigating parking lot entrances, the vehicle exhibits extreme "indecisive behavior," resulting in violent, rapid shaking of the steering wheel before completing the maneuver. Tesla customer service was formally notified of these dangerous system behaviors on August 14, 2026. A formal remote engineering log review has been requested from the manufacturer, as these sudden braking actions in active traffic pose an immediate threat to public safety.

In the last 18 months I have had 8 service visits relating to electrical issues. In the last 30 months: - I had my car computer replaced after it shorted out, and then had to have it replaced again the next week. - I had the same taillight short out twice in a row. - I have had the 12V battery replaced three times. - I have had multiple low voltage controllers short out over multiple service visits. - The sound system has shorted out once as well. - One time, I was unable to shift to drive because a heater had shorted out. Now, I have to replace my right headlight and passenger airbag occupancy sensor due to shorts as well. The right headlight goes out intermittently and the passenger airbag alert fires sometimes. Tesla Corte Madera submitted a buyback request on my behalf after witnessing all these issues, but Tesla corporate denied it. I am sure the electrical issues will continue to affect the safety and drivability of my car. Thank you for your help.

The forward-facing camera and Autopilot computer system on my 2021 Tesla Model 3 has failed. The dashboard first showed intermittent warnings that "Automatic Emergency Braking is currently unavailable" and "Adaptive headlight features are unavailable." Over several weeks the problem worsened from intermittent to constant, and the vehicle progressively lost its forward road visualization and all active safety features. Using the vehicle's Service Mode diagnostics, the Autopilot computer's Primary (A) processing node reports a "CRITICAL" status. The fault log records repeated alerts including dasMIA (driver-assistance system not responding), aebFault (automatic emergency braking fault), and fisheyeCamInitFault and fisheyeCameraStreamExit (forward camera initialization and stream failures). The cameras themselves are physically clean and unobstructed. Safety risk: the failure disables Automatic Emergency Braking and forward collision avoidance, lane-keeping/driver assistance, and the adaptive auto high-beam headlights. AEB is a critical crash-avoidance system; losing it leaves the vehicle unable to brake automatically for an imminent collision, and the loss of adaptive headlights reduces nighttime visibility. A Tesla service center inspected the vehicle, confirmed the diagnosis, and determined the Autopilot computer — a sealed, solid-state control unit — had failed and required full replacement at approximately $3,400. The vehicle is well under 50,000 miles. This failure appears consistent with the same car-computer power-component shorting failure for which Tesla issued a recall on its newer model-year vehicles. The vehicle and the failed component are available for inspection on request. The vehicle has not been inspected by police or insurance.

I was involved in a collision while driving my 2019 Tesla Model 3. The incident occurred on April 2nd 2026 in [XXX] Prior to the collision, the vehicle was operating normally The crash resulted in damage to the front driver-side of the vehicle, including a destroyed headlight and body panel damage. At the time of the incident, weather and traffic was light and normal. The vehicle was set and supposed to head straight when suddenly at the intersection it jerked right and headed straight into another vehicle. I attempted to take control but was unable to due to resistance on the wheel and how quickly the incident occurred. There was no warning or emergency braking which should've also been expected from my tesla. I am submitting this report to document a potential safety concern and request review.

Incident Description (in my own words): This incident occurred in the parking lot of the [XXX] in Bretton Woods, New Hampshire. It was evening after sunset. The parking lot was dark but illuminated by overhead parking lights. My Tesla Model 3 headlights and vehicle lights were fully on. I was reversing slowly out of a tight parking space, traveling approximately 2–3 miles per hour. I was intentionally moving cautiously. My attention at the time was focused on the front right corner of the vehicle, as clearance there was tight. While reversing, the rear of my vehicle struck a parked truck behind me. The truck was relatively high (its headlights were positioned high on the vehicle). Neither I nor my passenger heard any rear collision warning, cross-traffic warning, or parking alert prior to impact. The vehicle also did not apply automatic braking. The contact occurred at very low speed and resulted in only minor cosmetic damage (a small dimple/deformation), but I was surprised that no warning or braking intervention occurred. Based on prior experience driving this vehicle, the collision and parking warning systems are typically configured to warn early, and I had confidence that a warning or automatic braking would activate in this scenario. Following the incident, I conducted a simple test by placing cones in front of the vehicle to see whether forward collision warnings would activate. They did not. While I understand cones may not trigger frontal collision alerts, this further contributed to my concern about object detection reliability in low-speed scenarios. The vehicle’s cameras were clean and unobstructed. I regularly clean the camera lenses. I am filing this complaint because my confidence in the vehicle’s collision warning and automatic braking systems has been shaken. I recently submitted a similar complaint regarding a collision involving our Tesla Model Y, and these two incidents—on two different Tesla vehicles—raise concerns for me INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

This car uses auto-dimming rear view and side mirrors. However, the rear view mirror is only able to be dimmed automatically, or be disabled in the settings. The issue is that the dimming is not based on a light sensor at all, it is merely timed to dim around 30 minutes after sunset and return to normal 30 minutes before sunrise. I have confirmed this timing on many drives and it is repeatable. The safety concern is that there is no way to manually dim the rear view mirror, which is a big issue around sunrise and sunset when cars headlights turn on before the mirrors dim. This is especially an issue with larger trucks behind a sedan like my Model 3. The only option I have to fight the blinding glare from headlights is to manually move my mirror so that I can no longer see out of the rear window, which makes lane changes much more dangerous.

While driving, the side mirrors closed and the doors locked by themselves. Then, the front trunk opened, the rear trunk opened, and when I opened the door, the headlights turned on and the front trunk opened again. When I opened the door another time, the side mirrors didn’t unfold, and the headlights started blinking. At high speeds (over 50 mph), I hear a ticking or metal-clanking sound, which is really scary. The car seems to be acting on its own, following some strange “manual” or behavior pattern. I feel unsafe driving it.
