Tesla Model S Electrical problems by year

publicly disparaged the vehicle in a crowded waiting room, falsely claimed "there is no recall," and threatened that "if we do the recall, the car may not operate or be drivable afterward," flatly refusing service. As a 40-year automotive industry veteran (former Service Manager), I recognize this as an egregious attempt to leverage mandatory safety recall work for retail service revenue, violating federal compliance obligations under 49 U.S.C. Chapter 301. The unrepaired MCU failure creates an acute safety hazard, disabling critical functions including defrosters, climate controls, and rear-view display visibility. Logistics & Scope: Consumer refuses return to Franklin, TN facility due to hostility/obstruction. Requesting NHTSA record this non-compliance violation and compel Tesla Corporate to coordinate mobile service or transport to an alternative regional facility with loaner coverage, with full restoration of vehicle operability at zero cost to the owner.

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.

exposure to oncoming traffic while disabled. • No alerts appeared before the failure • Fault codes appeared only after the vehicle stopped • Vehicle required towing • Incident occurred under normal driving conditions • Tesla has denied responsibility or involvement It was serviced by Tesla a couple days before. During servicing they stated on one side the drive axle was not completely installed upon arrival. They stated they "popped it in for free but the drive unit will likely need replacement soon." Prior to this visit i have had no issues or alerts with these parts or systems, I declined any work to these areas. The next day after receiving my vehicle back, I discovered the coolant reservoir was completely empty. No warning was provided that the coolant system had been left unfilled, and the lack of coolant may have contributed to thermal damage in the drive unit or inverter. They denied any work they did involve these parts and denied any responsibility. They denied my request to have the car towed to their service center and diagnose it unless i paid for it. They also estimated the repair to cost me 6k without any further investigation. I request that NHTSA evaluate whether this failure mode represents a broader defect affecting 2012-2015 Model S drive units/inverter electronics and whether further investigation or recall is warranted.

in their charging identification system. Because I blocked my credit card to prevent fraudulent charges, Tesla's system repeatedly flags my account as having unpaid balances and automatically disables my vehicle's access to the Supercharger network until those balances are resolved. This creates a situation where my vehicle can be denied access to charging infrastructure even though the charges are fraudulent and unrelated to my vehicle's actual activity. The issue has occurred multiple times over several months and requires repeated calls to Tesla customer support to restore charging functionality. Loss of access to charging infrastructure can significantly impact the usability and operational reliability of an electric vehicle. I am requesting that this issue be investigated as a potential defect in the Supercharger billing or authentication system that could affect multiple vehicle owners.

replaced before the diagnostic test. The vehicle was repaired, but the failure reoccurred. The vehicle failed to shift into drive or move. The jack mode was disengaged. While driving, the rear wheels were screeching. The contact stated that the failure was related to TSB: SB-21-33-002). The vehicle was towed to another local dealer, Tesla Service Arlington-Glebe Rd (2710 S Glebe Rd, Arlington, VA 22206). The vehicle was not diagnosed or repaired. The battery was at 19 percent. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 108,000.

instrument cluster malfunction to the officer at the scene and showed him the blank display. I took my vehicle to Tesla Service Center in Duluth, GA (3380 Satellite Blvd) on November 4, 2025 - as soon as I could get an appointment after the incident. Tesla cleared the filesystem caches but did NOT inform me about the existing eMMC recall (SB-21-21-001) that affects my vehicle, nor did they perform the recall repair. My 2013 Model S is equipped with the MCU1 with the 8GB eMMC that is subject to NHTSA Recall 21V-119. This is a known defect that NHTSA determined to be a safety issue because it affects critical displays including the speedometer, backup camera, and turn signal indicators. I have video evidence of the malfunction occurring and the Tesla service receipt documenting the issue. The fact that Tesla's service center did not notify me of the applicable recall or perform the free recall repair. This defect directly resulted in me receiving a traffic citation because I could not see my speedometer while driving INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

drain in this exact location, which this vehicle does not have. This design change appears to directly address the same water accumulation issue that caused the failure in my vehicle. The failure results in loss of the vehicle's ability to charge, rendering the vehicle inoperable. Tesla declined to repair the issue, stating the vehicle is out of warranty, despite acknowledging the design change in later models. This appears to be a latent design issue related to water ingress into critical charging electronics, which presents a safety and reliability concern due to loss of propulsion capability and water exposure to High Voltage parts.

provided photo evidence of the screen rebooting while driving. Tesla has refused to address this as a recall or safety repair. Tesla claims the recall was previously completed under a prior owner but refuses to provide any documentation proving that the recall repair was actually performed, citing prior owner privacy. Tesla has further stated that diagnosis of this active safety defect would be customer-paid due to the basic warranty being expired and has indicated that the only path forward is a paid infotainment upgrade. Tesla is effectively requiring payment to diagnose and resolve a known safety defect. As the safety defect is actively occurring while driving and Tesla has marked the recall as complete without providing proof or correcting the issue, I am requesting NHTSA review whether Tesla is improperly closing out recalls without ensuring the defect has been remedied and whether charging customers to diagnose known safety defects is appropriate. After entering my VIN into NHTSA's recall lookup, NHTSA shows Recall 21V-035 (MCU/eMMC failure) as Recall Incomplete for my vehicle. This directly contradicts Tesla's claim that the recall was previously completed. Tesla has refused to provide documentation and is requiring paid diagnosis and a paid infotainment upgrade despite the recall being listed by NHTSA as unresolved.

all ability to charge, loses all propulsion capability, and becomes a stranded hazard. This represents a safety concern because the vehicle can shut down without warning and cannot be moved, which could leave occupants stuck in unsafe conditions or traffic. The charge port failing to open is also a safety issue, as the vehicle cannot be charged in an emergency and the owner has no way to safely get the vehicle off the road once it loses power. Tesla quoted nearly $4,000 for repairs and refused goodwill assistance even though this is a known early Model S issue and these components have been redesigned in later models. My mother is on a fixed Social Security income and cannot afford the repair or even the diagnostic fee. This situation may cause her vehicle to be repossessed through no fault of her own. I am requesting NHTSA to review premature high-voltage component failures on early Tesla Model S vehicles, as these failures pose safety risks and leave owners stranded with no warning.

that it is safe to operate following the HV system failure and subsequent replacement of HV components. I am concerned the vehicle may have unresolved high-voltage or wiring issues that could pose a safety hazard.

Park and the emergency/parking brake would not engage. • The car became completely free-rolling, posing danger to myself, other drivers, and pedestrians. • When Tesla returned the car to my home, their technicians also could not get the vehicle into Park or activate any emergency braking system. • The car is currently stuck in Tow Mode in my driveway with physical objects placed behind the wheels to prevent it from rolling. Why This Is a Safety Hazard: A vehicle that cannot shift into Park, cannot use its emergency brake, and remains free-moving after a failure represents a serious safety defect. This occurred without warning and left the vehicle unsafe to operate or even store. Request: I respectfully request that NHTSA investigate this as a potential safety defect affecting the Tesla Model S when the high-voltage battery fails. A car should never lose all ability to secure itself.
