In Nov 2019, while driving at night, the center touchscreen (MCU) of my 2015 Model S went blank and would not recover after restarts. I lost access to nearly all vehicle controls. The daytime running lights remained on, but the headlights did not illuminate despite being set to auto, and I had no way to turn them on manually because the headlight control is on the failed touchscreen. Climate control was inoperative and the windshield began fogging, reducing visibility. I could not open the charge port despite a low battery. I avoided the freeway and took local roads home. This is the failure covered by Recall 21V035 (8GB eMMC wear-out). Tesla service confirmed via diagnostic logs an internal fault within the MCU and replaced it with a remanufactured unit. I paid $2,045.47 out of pocket (invoice uploaded). The defect was not remedied. The remanufactured MCU contains the same 8GB eMMC; since the 2019 replacement the screen still goes blank 2-3 times per year, recovering only after 10-15 minutes of holding the reboot buttons. As of Aug 2026, the federal safety agency's VIN lookup shows Recall 21V035 as "Recall Incomplete": Tesla has never performed the free remedy (64GB eMMC daughterboard). Component available for inspection. In Feb-Mar 2021, Tesla notified me my vehicle was covered and invited a reimbursement claim per its the federal safety agency-filed plan (49 CFR 573.13). I submitted the claim through my Tesla account within the claim period. Tesla's portal confirms this: it displays "You have already submitted for the reimbursement" and blocks resubmission (screenshot uploaded). The plan commits to a decision within 60 days. Five years later: no decision, no payment. In Feb 2026, Tesla Support confirmed it has no mechanism to check or process reimbursement claims. I am reporting Tesla's non-compliance with its filed reimbursement plan and its failure to remedy this recall.

The vehicle has suffered a catastrophic, intermittent low-voltage network crash caused by a failing Body Control Module (BCM), resulting in multiple dangerous safety-critical failure modes. On a previous occasion, the vehicle woke up with severe network faults and automatically forced itself into Neutral. When the driver stepped out to get the child and shut the door, the system crashed entirely and the exterior electronic door handles failed to present, trapping an infant child inside the running vehicle. Most recently, while driving in a rainstorm, the vehicle suffered a complete failure of the windshield wipers, a total loss of the high-beam headlights, a total loss of the horn, and a total loss of electronic communication to the electronic parking brake system. Most critically, the vehicle experienced an uncommanded propulsion hazard where it hard-locked itself in the 'Drive' gear and absolutely refused to shift into 'Park' or 'Neutral,' forcing the driver to physically maintain heavy hydraulic brake pressure to keep the vehicle from creeping forward. Because the horn failed and the parking brake was disabled, the driver was trapped in the driver's seat holding the brakes and was forced to call 911 for emergency first responders to come and physically block the wheels so the driver and infant could safely exit. Tesla Service has diagnosed the issue as a failed central Body Control Module (Part #1010906-00-D), but the cascading network failure modes present an extreme, life-threatening hazard regarding vehicle control and child entrapment.

Vehicle lights turned off while driving home with my family. Pulling over and turning off and on the car reset the problem. When lights turned off I received a warning light identifying a faulty right headlight and faulty left headlight. No accident and vehicle is currently outside manufacture warranty.

Tesla designs a single piece headlight with no serviceable parts. This includes headlights, high beams, and namely daytime running lights. All of these components are on an LED strip that overheats and un-solders due to this high heat, which causes premature failure. Some owners have reported as little as 3 months of life before failing. The daytime running lights are essential for safety driving in low light situations. These daytime running lights are seemingly built to fail. The lights dim then eventually no longer work. Tesla's solution is to have the customer purchase a brand new headlight at $2,500. My vehicle is 2018 Tesla s with 43,400 miles and always kept in carnage. Tesla should either goodwill swap out these headlights for a non-built to fail component, or offer a repair for a quality LED strip with proper heat distribution. Without daytime running lights safety is a major concern on foggy, rainy, and low light situations. I have attached an image showing how the failure begins on top then slowly goes all the way down to the side of the headlight which fails later,.

multitude of electrical problems: Fuel/Propulsion System, Lighting, and body controls along with all ADAS: Adaptive Cruise Control, Automatic Emergency Braking, Blind Spot Warning, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance systems are impacted by random intermittent glitching as computer screen bubbling progressed with goo leaking out of the bottom of the main computer. Most recent symptom was disabling of ALL ADAS systems along with automatic high beam headlight switching. Long ago as screen began to bubble and express fluid the low windshield washer alert came on and remains even when the tank is full. Then the charge port responsiveness degraded and stopped automatically functioning requiring user to bypass by clicking the "open charge port", then waiting 3 seconds, then tapping "unlock charge port". User must perform this as remote manual operation from a NACS charging handle button push will FAIL. Long ago the computer controlled 'home link' module would have excessive time delays on the order of hours or days from when the user would program and or operate the function. I even had a "phanthom" car appear by the computer calculations with E-Braking before the ADAS system failed fully, a 1.0 Tesla system should not have that... Windows have randomly rolled down and the driver side rear door will unlock and open on its own as the door handles present themselves. The safety risk class is unknown unknown; if the root problem is the screen filling leaking on electronics any number of unknown, unplanned, unstudied risk failure modes exist that can not be predicted. Schematically the HOMELINK is on connector X429 sharing CANBUS connections impacting safety: Driver "Instrument Cluster", DAS systems connected to "Power Steering ECU", "iBooster ECU", "ABS / Stability ECU", "Passive Restraints Controller"... see CAN Network - Chassis drawing page 11 , "Energy System - Charger Logic Connections" "Instrument Cluster / LIN" pg35

The contact owned a 2014 Tesla Model S. The contact stated that while driving at an undisclosed speed on the highway, the vehicle exited into a tunnel. The contact stated that his hands were on the steering wheel and that the steering wheel did not move; however, the vehicle inadvertently made a sharp left turn, and the passenger-side headlight struck the tunnel wall. The vehicle spun rapidly, and the contact's head snapped to the right. The air bags did not deploy. The contact received medical attention for whiplash. Police were made aware of the crash but did not arrive on the scene. There was no police report filed. The contact pulled over on the shoulder of the road and then restarted the vehicle. The vehicle had driven for a mile when the tire pressure dropped to zero. The vehicle was towed to the residence and then to a tow yard, where it was deemed totaled by the insurance company. The manufacturer was made aware of the failure. The failure mileage was approximately 180,000.

Tonight, shortly after dusk, on a lightly traveled road near my home, the high-beams failed to function as described in the manual, or according to any alternative way to activate them. Traffic is 30 MPH with a single lanes divided by a double yellow center line with cat-eyes. This area frequently has deer and other wildlife. Accordingly, whenever possible, high beams should be activated. Conditions were dry, and clear, without oncoming traffic -- while driving at or near the posted limit. Pushing and persistently holding the high-beam light maintained high-beam only while pressing the high-beam marked part of the steering wheel. Typical operation, in the past, operated the high beam if the button (capacitative sensitive surface on the steering wheel) was held in for about a full second and then released. This is no longer how it operated tonight. Driver pushed the high-beam for a full second. Upon release the high beams reverted to normal low beams. Driver repeated this 2 more times. After doing this twice, the driver is already distracted from wildlife and starting to focus on the car -- looking for error messages of some kind. After three times, its clear that it is Tesla software that is broken. Although the car is in good repair, no messages were presented. Again, conditions were clear and dry. Failure to operate visibility mechanisms is highly contrary to safe driving. Some features which should always work: 1. Wind shield wipers; 2. Defogger 3. Defroster 4. head lights 5. high beams Hopefully, Tesla has not abandoned functional high-beams like they have with Full Self Driving. On the other hand, if FSD is no longer among the executive compensation goals, perhaps providing a visible landscape to the all-camera FSD algorithm is also superfluous.

I don't have this problem anymore because I had the circuit board replaced. The issue I have observed is the auto high beam feature doesn't work properly. They get stuck in the high setting and don't adapt to on-coming traffic. It's primarily in model y cars but all models have been observed. This might be as simple as needing the adaptive setting to be default or in my case a new control board replaced. The remedy before I got it fixed was to not have high engaged with the stock. I don't think there is a manual solution with the y or any newer teslas.
