2023 Tesla Model Y: headlights failing or too dim

Filed Nov 2, 2026 · Brakes, Electrical · AZ

I am writing to formally escalate the recurring and increasingly serious technical and safety issues with my Tesla Model Y. Since July 2026, my vehicle has experienced multiple system malfunctions despite three service appointments, including the replacement of the vehicle computer during the most recent service. The frequency, severity, and nature of these failures have raised serious concerns regarding the vehicle’s reliability, roadworthiness, and overall safety. What initially appeared to be intermittent system alerts has now escalated to situations involving reduced propulsion, loss of critical vehicle functionality, and the vehicle becoming completely immobile while driving. I am extremely disappointed that these issues continue to occur even after multiple service interventions. I no longer have confidence in the vehicle’s ability to operate safely and reliably. he above incidents, combined with the repeated failures since July 2026, demonstrate a pattern of unresolved and potentially serious vehicle malfunctions. My concerns include: Repeated Park Assist and Adaptive Headlights malfunctions. Camera failures and abnormal vehicle visualizations. Vehicle computer replacement without lasting resolution. Electrical system power reduction and potential vehicle shutdown. Front motor disabling and reduced propulsion. Sudden reduction in acceleration and maximum speed. Windshield wiper failure during rainy weather. Automatic Vehicle Hold becoming unavailable. Automatic Emergency Braking becoming unavailable. Lane Departure Avoidance becoming unavailable. Vehicle becoming completely immobile while driving. Potential inability to restart the vehicle. Failure of driver-side door and trunk access. Unpredictable vehicle behavior and loss of confidence in its safety. These are not merely inconvenience-related issues. They involve fundamental vehicle operating systems and safety-related functions.

2023 Tesla Model Y – HW3 Autopilot computer/camera system failure My 2023 Tesla Model Y has approximately 54,000 miles and is equipped with the Tesla Hardware 3 (HW3) Autopilot computer. After receiving Tesla's FSD v14 Lite software, the vehicle began intermittently losing camera-based driver-assistance functionality. I observed an APP_w141 ECU Thermal Issue alert. The vehicle subsequently experienced APS_w134_appMia and APS_w135_appCritical alerts indicating that the Autopilot Processor Secondary was losing communication with and detecting a malfunction of the Autopilot Processor Primary. When the problem occurs, camera/vision functions and driving visualization become unavailable or degraded, and the vehicle has reported Self-Driving Features Limited, Cruise Control Unavailable, Adaptive Headlight Features Unavailable, and other driver-assistance limitations. In Tesla Service Mode I have documented the primary Autopilot processor repeatedly changing between INIT, CRITICAL and COREBOOT while the secondary processor remains NOMINAL. A DAS reset can temporarily restore communication, but the failure returns. Tesla has proposed replacing the entire HW3 car computer at a cost of approximately $3,120. I am concerned that this may represent a safety-related HW3 computer failure, particularly because I observed an ECU thermal alert and because the failure removes multiple camera-based driver-assistance and safety functions. I have photographs documenting the alerts and processor states and have an open Tesla service case.

I am filing a complaint regarding the low-beam headlights on my Tesla. The headlights emit an excessively bright glare that impairs the visibility of oncoming traffic and surrounding motorists, creating a hazardous driving condition. This issue corresponds to federal safety non-compliance under FMVSS No. 108 and the federal safety agency Recall Campaign No. 26V507, where the low beams were found to output up to 230.1 candela, nearly doubling the legal federal limit of 125 candela. The excessive illumination creates a 'veiling glare' that threatens highway safety, particularly during inclement weather conditions such as rain, snow, or fog. I request that my vehicle be physically inspected and serviced with compliant hardware components as outlined by federal regulators.

On XXX I retrieved my 2023 Tesla Model Y (VIN: [XXX]) from Tesla Motors NV, Inc. ([XXX]) after their third attempt to correct a severe panel and component misalignment following a collision repair (Invoice #XXX). The facility replaced major front-end structural components, including the Front Bumper Beam (1687601-00-E), Front Subframe Crush Can (1109193-00-C), and Cast Front Underbody Left Hand Crush Can (1608453-00-D).Tesla's official guidelines require a mandatory 3D structural measurement test whenever these specific cast aluminum underbody and subframe parts are replaced. The repair facility verbally claimed the damage was minor/cosmetic and that only a manual tram measurement was performed. However, a manual tram gauge cannot detect 3D frame twists or height deviations in cast aluminum components, making it wholly insufficient.As a direct result of this unverified structural alignment, the vehicle's front end remains warped. After the first repair, the headlamp shifted and protruded on the right side. After subsequent attempts to fix it, the left headlamp is again protruding outward. Because the structural frame is misaligned, the forward-facing cameras are out of calibration. Under Autopilot, the vehicle exhibits dangerous behavior, including misidentifying a standard bike lane as an extended vehicle lane. Furthermore, the repair facility has since removed or hidden the conversation logs regarding these complaints, and I can no longer find the messages in the Tesla app. Operating a vehicle with unverified structural alignment and compromised driver-assist vision systems poses an immediate, severe safety risk.

The car's computer shorts out and disables all safety features including navigation, blind spot monitoring, all cameras, emergency braking, autopilot, lanekeeping, auto headlights and wipers. This is a known issue that Tesla will not repair. This resulted in a collision due to poor rear visibility, lack of cameras, and disabled emergency braking. In addition, intermittently there is loss of power steering. Despite this being a known issue, Tesla will not replace my computer, insisting I pay several thousands of dollars for the repair. I feel they must issue a recall and cover this safety defect. The car software cannot be updated, either. Please intervene. [XXX] [XXX] [XXX] I do not have the claim information for the other car involved, but can get from State Farm. I do have the repair costs for my vehicle.

While using Full Self-Driving on my 2023 Tesla Model Y, the automatic high beams repeatedly activate in active traffic conditions, including when following other vehicles and when oncoming traffic is present. The system does not consistently dim the lights, creating glare that could impair visibility for other drivers. The driver is unable to permanently disable automatic high beams while FSD is engaged.

This started at about 65000 miles in my 2023 Model Y. The rear camera first lost picture and I received a warning that it may be intermittent. It has progressed now to the point that autopilot, navigation, all cameras, cruise control, auto headlight, and auto wipers are all nonfunctional. The car does not know its location. All safety features such as lanekeeping, cross traffic alert, auto braking are disabled. The rearview camera no longer functions. Software updates no longer complete downloading. While there are numerous reports of computer short circuits in hardware 4 cars, the only solution I am offered is to have the computer replaced at my own cost of just under 3000 dollars. And that would be warranted only for one year or 12500 miles. Reviewing the submissions on the federal safety agency website as well as searching online, this problem is not infrequent. I do not feel safe letting my wife or daughter drive the car. Certain 2024 and 2025 models with this problem have been recalled for new computers. This must be expanded to include 2023 models as well.

Subject: Urgent Safety Concern – Steering Component Failure in 2023 Tesla Model Y Dear Tesla Customer Support / the federal safety agency Safety Division, I am writing to formally report a serious safety issue involving a critical steering component failure in my 2023 Tesla Model Y (VIN: [XXX] 38,917 miles). The failure led to a loss of control and resulted in a collision. On [XXX], my wife, [XXX] , was driving the vehicle on our residential street, shortly after leaving our driveway. At a low speed of approximately 8-10 mph, she suddenly lost steering control as the car rapidly veered to the right. Despite attempts to steer, the vehicle was unresponsive, leading to a collision with a parked car. Damage Summary: •Our Tesla Model Y: Damage to front bumper, headlights, right wheel cover and right fender. •Parked Vehicle: Deep scratches and dents on the rear driver-side bumper and passenger door. Upon inspecting the vehicle after the incident, it became apparent that a suspension or steering component (likely the lower control arm) had failed (broken). After researching online, I discovered that multiple Tesla Model Y owners have reported similar sudden failures of the same part, indicating a potential manufacturing defect. Request for Immediate Action: 1.Tesla Inspection & Full Repair at No Cost – Since my vehicle is under warranty and this appears to be a manufacturing defect, I request a full investigation and repair at Tesla’s expense. 2.the federal safety agency Investigation into a Potential Recall – Given that similar failures have been reported by other Tesla owners, I urge the federal safety agency to review this issue for a potential recall before more accidents occur. 3.Tesla’s Official Response – I would like Tesla to confirm whether this component has been investigated for defects in other vehicles and what steps are being taken to prevent other accidents. This incident could have been far worse had my wife been driving at higher speeds. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA)

Driving Incident with Auto High Beam: I was driving on the freeway early in the morning with the auto high beam feature activated. However, due to heavy fog, I wanted to turn it off. I asked my passenger to help me find the option on the screen. Unfortunately, she clicked the wrong button, which completely turned off all the lights while we were driving. This caused a moment of panic, and I had to slam the brakes, realizing I had veered off the road. Thankfully, there was no one behind us. While it was an oversight on my passenger’s part, I can’t help but wonder: shouldn’t there be a warning or a disabled button while driving, especially in the dark? I’m not sure if this qualifies as a safety issue, but it certainly felt life-threatening at the moment. Had there been another vehicle behind us or if we had hit a divider, the situation could have been much worse. Suggestion for Improvement: To enhance safety, I suggest implementing a feature that disables the off button in light controls while the vehicle is in motion, especially in low-visibility conditions. Additionally, a clear warning message could pop up if a driver attempts to adjust the lighting settings while driving, ensuring that safety remains the top priority.

I had the vehicle wrapped on July 5, 2024. The vehicle has never been in a collision. The shop whom did the work did a video of the install showing it was a manufacturer defect. Took the vehicle to Tesla and they denied my warranty even when showing them proof. Both left and right side headlights have the mounting issue which could cause undesired beam to incoming traffic. Bumper is the only thing holding the headlights.

The backup camera failed to display any image, even with a vehicle restart by pushing the 2 buttons on the steering wheel to force a vehicle restart. I cannot see the back of the vehicle without the camera as the rearview window is so up high that it creates blind spots that I cannot see to safely get in or out of a parking spot and this creates a huge safety risk. Warnings that displayed was emergency braking unavailable and park assist unavailable. Also, the headlights on this vehicle is too bright that other drivers are flashing their high beam at me believing that I had the high beam on when I only have the low beam on. This creates a safety risk as the lights blind other drivers on the road and the same make and model of the vehicle can also create visibility problems when traveling in the opposite direction as it can also blind me. Those matrix headlight that can dim certain areas and not blind other drivers should be standard and enabled by default on all vehicles, including this one.
