Electrical System Problems of Tesla Model Y - part 1

I am reporting multiple safety-related failures with my Tesla Model Y, purchased December 18, 2025. Within four months of ownership, the vehicle has experienced escalating issues: on April 19, 2026, while driving approximately 70 mph on a freeway in heavy rain, the vehicle suddenly lost power and decelerated to approximately 20 mph. Multiple safety systems became unavailable simultaneously, including automatic emergency braking, traction control, stability control, and vehicle hold. I was able to pull to the side of the road, but the vehicle would not restart and required towing. This created a dangerous situation and significantly compromised my ability to safely control the vehicle. On April 9, 2026, a rear seatbelt unlatched under braking while in use. This is a serious safety concern, as the passenger was not properly restrained and had to brace themselves. On February 10, 2026, the vehicle experienced repeated software failures causing lockouts. In one incident, I was locked out while my [xxx] child was inside the vehicle. On January 2, 2026, the vehicle required service for a cracked window shortly after delivery. The vehicle has been taken in for service multiple times, and although repairs were performed, new and increasingly serious failures have continued to occur. I am concerned about the safety of operating this vehicle, particularly due to the loss of power at highway speed and failure of safety systems. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The rear subframe wiring harness on my Tesla contains a significant design flaw that creates an unreasonable safety risk. The factory-installed corrugated protective tubing (wire loom) terminates prematurely, leaving approximately 1 inch of critical wiring completely exposed at the connector. This specific harness uses soy-based insulation, which is a known attractant to rodents. Because of the 1-inch gap in protection, rodents have been able to sever the same connector twice within a 30-day period safety risk: the exposed wires in the rear subframe harness are responsible for rear drive unit communication / wheel speed sensors / brakes]. A failure of these wires while the vehicle is in motion could result in a sudden loss of propulsion, unexpected braking, or the loss of stability control systems. This creates a high risk of a collision, particularly at highway speeds.

I am reporting a serious safety concern involving my Tesla Model Y. While driving, the vehicle’s main center screen (mcu) suddenly failed and entered a continuous reboot loop. This resulted in the loss of critical driving information and controls, including navigation, camera display, and vehicle system status. The issue occurred without any warning and nearly caused a serious accident, as I was unable to safely monitor essential driving information. This failure made the vehicle extremely unsafe to operate. The problem appears to be related to a known mcu system failure affecting some Tesla vehicles. I am concerned that this issue may present a broader safety risk for other drivers. Please investigate this matter for potential safety defects.

**what component or system failed or malfunctioned, and is it available for inspection upon request?** the vehicle experienced a critical failure immediately on the same day of purchase, rendering it not functioning or inoperable. It was deemed to be preexisting from the dealership I bought it from. The battery is malfunctioning affecting the driving capacity and range. --- * was your safety or the safety of others put at risk?** the failure created a significant safety concern, as the vehicle was not operating reliably immediately after purchase. This placed me at risk of being stranded and potentially exposed to hazardous conditions, including loss of transportation in unsafe or uncontrolled environments. Or stopping while driving. --- * the problem been reproduced or confirmed by a dealer or independent service center?** the issue was immediately reported to the dealership, and they acknowledged the problem by agreeing to an exchange of the vehicle due to its defective condition. It was confirmed by a service center of the car's manufacturer. --- * the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?** at this time, the vehicle has inspected by the manufacturer. --- **were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?** yes, although the manufacturer can't pinpoint when they started but said they had been on since atleast March 10. My purchase was made April 1, undisclosed to me of this huge issue.

My 2023 Tesla Model Y suddenly became inaccessible via key card and phone key with no prior warning. The tow operator successfully jump-started the vehicle with a 12v jump and it powered on — suggesting a 12v battery failure, not an hv system failure. Tesla diagnosed water ingress in the hv battery pack and hv harness, citing an isolation resistance fault and open flood port. Their conclusion escalated from "water ingress" to "vehicle submerged," with an $11,000 battery replacement recommended and warranty denied. I am disputing this. The vehicle has never been submerged or exposed to flooding. The only physical evidence provided was clean water droplets on a single hv connector — no waterline staining, no sediment, no debris, no pin corrosion. No ingress pathway (seal, gasket, or breach point) was identified. The flood port mechanism was not explained and may activate from pressure changes or seal failure — not exclusively submersion. The vehicle powering on after a 12v jump is inconsistent with catastrophic hv failure from submersion. I believe this may represent a manufacturing defect in the hv battery pack sealing system allowing moisture intrusion under normal conditions. Tesla has classified this as owner-caused damage without sufficient physical evidence. If similar cases exist across 2023 Model Y vehicles, a systemic defect may be present. Safety risk: sudden, complete vehicle shutdown with no warning — potential loss of propulsion while driving. Vehicle is currently at Tesla service, undisassembled, and available for inspection.

Upon delivery of the vehicle the passenger door would not open from the outside. Multiple vehicle settings were reviewed, and a repair was scheduled to fix the issue.

On March 23, 2026, my vehicle experienced a sudden and simultaneous failure of multiple critical safety systems without any prior warning. The alerts displayed included: automatic emergency braking unavailable, traction control disabled, stability control disabled, and additional driver-assistance features becoming unavailable. This incident created a serious safety hazard, as the loss of these systems significantly reduces vehicle stability and braking assistance, increasing the risk of loss of control, especially at highway speeds or in adverse weather conditions. In addition, the front-facing camera exhibits fogging and reduced visibility during cloudy and rainy conditions, which further impacts the reliability of safety and driver-assistance systems. Based on my research, similar issues have been reported by other Tesla owners, suggesting this may not be an isolated incident but a potential pattern defect. I am concerned about the safety of operating this vehicle and request that this matter be investigated for potential defects affecting critical safety systems.

I was entering the on-ramp to [xxx] , from [xxx] , to merge onto the freeway east bound towards [xxx] , when my Tesla suddenly lost all power, the brakes did not work and the power steering completely failed making it feel like it was locked up. I was traveling approximately 40-50 mph at the time nearing the gore point to merge onto the freeway. Fortunately I was in the inside lane and I rolled to a stop away from other vehicles. I could not steer at all. Had I been completely on the freeway, I could have been rear ended badly. I had my two young boys in the vehicle with me, both [xxx] and [xxx] . We were completely trapped in the vehicle with no power. My [xxx] old remembered to use the manual latch to get out. I opened my door manually and it broke my driver side glass window. Vehicles were passing us rapidly to enter the freeway. I called my husband who is a police officer and he came and picked us up. We called Tesla who said they could not get a read on our battery whatsoever. We called a tow company and had this vehicle towed to Tesla repair center in [xxx] , after reporting our traumatic event. They claim our warranty is expired, but our vehicle only has 37,638 miles and should be covered under the 8 year, 120,000 mile warranty that covers a major malfunction like this. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While on my way to run an errand, I opened up the back door to strap my 2 year old in, when I closed the door, the car would not open whatsoever, after trying for a few minutes with the phone key app for Tesla and the physical key fob, nothing would work. I had to end up calling 911 and firefighters came out and had to physically open the door, which broke the window. The car was completely unresponsive and would not turn on. After researching what happened, it turns out the 12v battery had died. I was able to jumpstart the car with jumpers and that was able to open up the rest of the car's doors. However, during the time my son was stuck inside with the over 95 degree weather, the had no safety mechanism in place to open it physically like a traditional key fob would. It is very disheartening knowing my son could have potentially lost his life over something so simple that could be resolved with a physical keyhole on the outside like almost every traditional vehicle has. This is something that should not occur, ever. The fact that the car was able to open up once more before completely dying and perfectly at the wrong time after closing the door while my son was trapped in there in complete heat was very disappointing.

Following a "secondary" botched windshield replacement within 3 weeks performed by the Tesla service center in carle place, NY, my Tesla Model Y experienced a catastrophic structural water intrusion during rainfall. A great amounts of water dripping directly through the windshield seal into the cabin, soaking the dashboard electronics, floorboards, and much more water coming in from the brake pedal area while driving on lie. While I was driving the vehicle with my three children in the back seat, this water intrusion triggered an active electrical short circuit. The vehicle's hazard lights began flashing autonomously, and the electrical system became severely compromised, creating an immediate and life-threatening safety hazard on the road. The vehicle is currently grounded, completely undrivable, and poses a continued electrical fire risk. Tesla service has been notified in writing and has officially acknowledged via their app that the vehicle must be towed. This gross negligence in structural sealing has directly compromised the vehicle's electrical control modules, severely endangering the lives of the occupants. ".

My driver side headlight assembly stopped working. The headlight assembly includes the driving lights, high beams, and turn signals. I am open to having this product inspected upon request. This impacts the safety of me and others due to decreased visibility and the inability to appropriately indicate when I am turning. The dealer has not reviewed this yet, but I have a scheduled appointment on Friday, April 24. Vehicle has not been inspected by any third-party, improving manufacturer, police, insurance, or other representatives. There were no warning, lamps, messages, other symptoms of the problem prior to failure. The failure first appeared at around 55,000 miles, which was 5000 miles beyond my warranty. I believe that Tesla is pushing out updates that intentionally cause light assemblies and other high priced items to stop working after the warranty. There are multiple instances people replacing the same fixture after their warranty period has expired. Tesla charges $2000 to replace one light fixture. I believe this is fraudulent and corrupt business practices by Tesla.

The front trunk (frunk) actuator failed due to an under voltage condition. During repair, Tesla technicians also found corrosion in the wiring harness connectors. The vehicle has been garaged its entire life and has never been exposed to harsh environmental conditions. Tesla's own service documentation specifies that underwood and underbody connectors should be protected with anti-corrosion grease during assembly. Premature corrosion on a grade vehicle at 78,000 miles suggests a manufacturing defect in either the harness materials or the factory assembly process. Repair cost $860. 20, partially offset by a $200 goodwill credit. A non-functional frunk also represents a potential safety concern as the hood latch mechanism is part of vehicle safety systems.

On [xxx] I pick up my new Tesla y. On [xxx], while traveling at highway speeds on [xxx] with autopilot "fsd" engaged, my 2026 Tesla Model Y experienced a sudden vehicle shutdown and start giving multiple alerts without warning. The vehicle displayed multiple critical alerts: "vehicle shutdown", "pull over safely", "stability control disabled. " upon the failure, autopilot fsd disengaged, and the power steering immediately became extremely heavy ("hard"), making the vehicle difficult to steer. The car lost all propulsion. I had to manually maneuver the heavy, unpowered vehicle through active highway traffic to reach the shoulder, which created an immediate and severe safety risk. The vehicle was towed to a Tesla service center in fort lauderdale with only 130 miles on the odometer. Technicians confirmed a "major motor failure" of the rear drive unit requiring a full replacement. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle was delivered with a critical safety defect in the braking system and inoperable safety software (gps/fsd/navigation). Upon further inspection by the dealer's own technician, it was confirmed that the vehicle had 'extremely poor brake feel' and 'extreme rust build up' on all pads and rotors, which violated Tesla’s 6mm minimum safety standard for used vehicles. Additionally, a physically damaged windshield harness caused the failure of gps and fsd features. These defects posed a significant safety risk to myself and my family during operation. The dealer has documented and confirmed these safety issues but is now refusing a buyback and is retaliating with storage fees for my rejection of the unsafe product. No warning lights appeared prior to the technician's discovery of the brake defects.

Driver side front window auto rolled back up after pressing the button to once to roll it down. This happened while driving while the right hand was on the steering wheel. The left hand got caught inbetween the window glass and the window frame as it auto rolled back up on its own. It caused bleeding and pain to the left hand.

The contact owns a 2026 Tesla Model Y. The contact stated that the Model Year was advertised with a front trunk emergency release and interior lighting. The contact stated that after purchasing the vehicle, the contact became aware that the vehicle was not designed with the front trunk emergency release or interior lighting, which the contact considered a safety issue and a violation of fmvss no. 401. The Tesla service center was contacted and confirmed that the Model Year and other vehicles were no longer designed with the missing parts. The manufacturer was notified of the issue. The failure mileage was approximately 570.

Vehicle information 2025 Tesla Model Y approx. 30,000 miles purchased new ~11 months ago incident description while driving at highway speed, the front trunk (frunk/hood) of my 2025 Tesla Model Y unexpectedly opened. The hood immediately flew upward, flipped backward over the windshield, and shattered the windshield. The frunk had not been opened in approximately two weeks prior to the incident. The vehicle had not undergone recent service or repair involving the hood or latch assembly. There were no prior warnings or alerts indicating that the frunk was unlatched or not latched properly before driving. The hood appeared fully closed prior to the trip. However, after the incident once we pulled over, a bolt was completely out of place, as shown in my video. Even if the primary latch was faulty, the secondary latch / catch should have prevented the hood from opening all the way and slamming the windshield. This failure to notify improper latching created an immediate and total obstruction of forward visibility at highway speed and posed a serious crash risk. The vehicle has approximately 30,000 miles and is less than one year old. Given Tesla’s prior recall related to hood latch detection issues, I am concerned that either: •the latch system failed mechanically, and/or •the vehicle failed to properly detect and warn of an unlatched hood. This is a significant safety event and could result in serious injury or death if it occurs in traffic.

The vehicle display flashed red and then the vehicle turned off completely while in traffic with no ability to change gear, operate the electronic door releases, or turn the hazards on. Safety was put at risk because insufficient notice of failure was given so it was impossible to get out of traffic, the vehicle could not be put in neutral so could not be pushed out of traffic, further the hazard lights could not be turned on so I had to stand in traffic waiving people around the vehicle. Because the electronic door releases didn't work, the doors could not be opened from the outside, had a front window not been open, it would have been easy to trap our child in the car. The dealer confirmed that the failure took place from vehicle logs but was unable to reproduce the problem. The dealer/manufacturer inspected the vehicle. Prior to this happening the vehicle showed warnings that power was reduced and vehicle may not restart about 20 minutes prior to the event, but the warnings disappeared after a minute. Even though Tesla confirmed the failure, they refused to diagnose the problem or fix it so the vehicle remains dangerous.

Tesla Model Y 99,000 km it is known issue with many driver of same model and milage that wire harness connected to oil pump gets hot and damage. This can also cause fire. Many people have been complaining about similar issue on facebook group.

Vehicle experienced pcs (power conversion system/DC-DC converter) failure, rendering it completely undrivable—no 12v power, cannot charge or start. Pcs is physically integrated inside high-voltage battery pack per service manuals. High-voltage battery warranty active (8yr/120k miles). Tesla service denies coverage citing "associated component" in vague emails—provided only general warranty table, no specific exclusion language despite repeated requests for exact quote/formal written denial. Escalated to managers: offered "view-only" internal service bulletin on screen at meeting—no print/copy/photo allowed. Explicitly refused formal written denial letter.

All safety and most computer related features in the vehicle have failed. Cruise control, backup cameras, all other cameras, the navigation (assuming this is also impacting the projection of remaining battery life as my car always thinks it is at my home), warning signals for approaching obstacles/dangers, cruise control of any kind does now work, lane departure warning has failed, and automatic windshield wipers do not work. This happened without warning and was not related to an update. On January 13, 2026, the car worked in the morning and then all of these issues started happening. I made a Tesla service appointment, but they are not able to see me until February 3, 2026.

Observed intermittent center display/infotainment computer (mcu) crashes/reboots where the center display becomes blank and then restarts. In recorded events, when reverse was selected during an mcu reboot interval, the rearview camera image did not display until the reboot completed. Recorded rear camera unavailability during reverse was approximately 10–17 seconds. Mcu crash/reboot behavior was observed to be repeatable, including predictable occurrence while the vehicle was in the built-in service mode. After a factory reset, repeated/double boot behavior was also observed. Additional observations: - with the turn signal activated, light leakage was observed in the side repeater camera image (glare/bloom present in the camera view). - with each windshield wiper sweep, the forward camera image was observed to briefly flicker to a purple/green distorted state and then return to normal. - during driving, the on-screen message “auto lane change unavailable” was observed. A separate rear camera symptom has also been observed: intermittent freezing/stale frames (image appears not to update). This rear camera freeze behavior has not yet been captured on video. These conditions have been documented by video/screenshots and reported to the manufacturer/service center for inspection/diagnosis. No crash or injury occurred. The vehicle is currently located at the manufacturer’s service center and is available for inspection upon request.

Urgent safety defect – child injury 2026 Model Y, rear right window. While a child was entering the vehicle and the door was closing, the power window trapped the child’s fingers. Pinch protection failed to reverse. The vehicle locked and the windows closed while the child’s fingers were trapped. Injury occurred. Request immediate safety investigation, preservation of vehicle logs, and written findings. Vehicle must not be altered prior to inspection.

I got into my car two days ago and the computer screen was black. I have tried everything to reset it, holding down both scroll wheels with the brake pressed for up to 2 minutes, unplugging the low voltage battery overnight and plugging it back in, and even doing the hard reset at the disconnect under the rear passenger seats and my computer will not turn on. I can't see any information about my speed or how much charge I have, I can't turn on climate controls and it's the middle of winter and I live in the mountains of colorado. I can't even open my glove box without the screen. From everything I read, it sounds like an mcu failure, my vehicle has the newer mcu2. Tesla quoted about $800 for a tow and it sounds like the replacement costs could be $2500+.

Tesla decided to remove the safety unlock illuminated button from its front trunk (frunk) sometime in mid 2025. This can be a safety issue which was present in earlier models and against the federal motor vehicle safety standard (fmvss) 401, mandating an interior release mechanism for enclosed trunks to prevent entrapment. I contacted Tesla and they told me that my vehicle was made after Tesla decided to remove this safety feature.

A few weeks ago my seatbelt censor started acting up, and then two weeks later that my heater quit. They blamed chewed wiring because of soy based coatings, and set its not in the warranty and accused rodent damage since the rear seat was eaten. I got the call during diagnosis demanding I bring the loaner car because they wanted $1,349. 07 which I did not have because a 9/11 first responder and don't have other insurance accept mandated state minimums, they told me bring the loaner back, on the way home fsd worked till I got towards my putnam county rural route 22 when power steering fsd and power breaks died. I skidded at 25 mph managed to get to park and plug it and leaving it this. So the tech put the plugs together and made the situation worse by plugging chewed harness together. No heat, transport, no car, no door dash money for me, no medical appointment and cant risk losing all steering. When Tesla works, it works very and great car. Had they refused to use soy coatings and stayed with rubber coatings this issue would not be here. How many fsd crashes are result of rodent damage?.

The contact owned a 2023 Tesla Model Y. The contact stated that a software update (2025. 44. 25. 5) was performed on the vehicle, which was for a temporary free self-driving mode. The contact stated that while driving at approximately 75 mph, the vehicle independently accelerated sideways and crashed into the highway's concrete retaining wall. The air bags deployed upon impact. The contact was taken to the hospital by ambulance, where he was treated bruised left knee, cracked ribs, and several other bruises to various parts of his body. No property damage was reported. A police report was filed. The vehicle was towed from the scene to an independent mechanic, where it was deemed a total loss. Neither the manufacturer nor the service center had been notified of the failure. The failure mileage was approximately 22,500.

Incident summary: car computer (hw3) suffered internal hardware failure on 12/17/25 following software update 2025. 44. 3. While the media screen and rearview camera functioned, the autopilot board (apb) was "mia. " Tesla randolph (invoice #3000s0015357298) confirmed the internal failure and replaced the unit. Safety risk: failure disabled safety-critical adas: automatic emergency braking (aeb) and forward collision warning. Driving visualizations were severely compromised; the vehicle failed to detect pedestrians or lane markings while in motion, creating an immediate collision risk. The car’s active safety "intelligence" was essentially blind despite the camera feed being visible on the screen. Inspection & contradictions: Tesla service confirmed the "internal failure" (12/19-12/23). Note: the service manager verbally claimed "no codes," but the official invoice explicitly states technicians "found multiple alerts present. " part was retained by Tesla. Warning symptoms: failure followed a software reboot loop. Symptoms (mia board/power cycle failure) match recall 25v-002. Vehicle had only 36,289 miles. Reporting as potential hw3 defect expansion.

The car stopped in a busy freeway saying electric issue and doesn’t give sufficient time to drive to shoulder. This is the 2nd time this happened within 2 weeks. First time, Tesla said high voltage controller had an internal issue with voltage sensing. The hv controller was replaced along with pyrotechnic fuse. Tesla assured this shouldn’t repeat and it repeated again. This has kept us in a catastrophic situation. I request immediate attention to this error and matter.

Date of incident: December 8, 2025 mileage at failure: approx. 580 miles vehicle status: at Tesla service center since December 9, 2025 (no repairs started; status shows “preparing”) failure summary while driving 40–45 mph on a busy three-lane road in California, approaching a signalized intersection, the vehicle suddenly displayed multiple red warnings, a “reduced speed” alert, and numerous fault messages. Within 3–5 seconds, propulsion was completely lost. Incident details using residual momentum, I steered across two lanes into a nearby retail parking lot. The vehicle stopped at an angle, partially obstructing traffic. Towing delay & safety risk the vehicle remained stranded for ~4 hours. A flatbed tow arrived ~2 hours later but could not load the vehicle due to inoperative tow mode. A second dolly-equipped tow truck was required, adding ~90 minutes. During this time, the vehicle continued to block traffic and posed a safety hazard. Component/system failure complete propulsion loss and failure of major electrical/control systems, including doors, frunk, trunk, tow mode, and non-responsive key card and phone key. Vehicle remains inoperable. Safety hazard sudden shutdown in a center lane near a major intersection left almost no opportunity to maneuver safely. Extended roadside immobilization and inoperative tow mode further increased risk. Warning prior to failure none, except 3–5 seconds of simultaneous red warnings and fault messages. Problem status ongoing and unresolved. Tesla has not diagnosed or repaired the vehicle and continues to delay the estimated repair date. Inspections vehicle is under evaluation at Tesla service center. No repairs, police, or insurance inspections have been conducted.

I’m reaching out to document and summarize an incident that occurred in sanford, florida, and to ask for the appropriate next steps and any documentation you may need from me. Incident summary (sanford, FL – appaloosa court – Dec 2, 2025): in the early morning on Tuesday, December 2, 2025 (around 5:00–5:15 a. M. ), a fire occurred at a residence located on [xxx] . A Tesla located in the garage was reported as being involved, and the fire spread to the garage that totaled the house the vehicle was reportedly charging in the garage when smoke/fire was noticed. Emergency responders (sanford fire department and sanford police) responded to the scene. The incident resulted in property damage and at least one injury reported as non-life-threatening (per local reporting). Fire forensics stated that the fire started and caused by the Tesla around the charging plug area by the rear left passenger door. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

To the national highway traffic safety administration, I am filing a formal complaint regarding a dangerous safety defect in the 2021 Tesla Model Y. On December 2, 2025 at approximately 4:25 pm, my vehicle suffered a sudden, complete electrical shutdown while I was driving, with no warning and no opportunity to reach safety. Critical details: the vehicle displayed an electrical system message, then instantly powered down. I lost all ability to steer or move the vehicle, which remained immobilized in active traffic. Hazard lights did not function, leaving the vehicle unmarked and invisible to oncoming vehicles. Electronic systems failed, requiring manual release of the driver door. The incident occurred at dusk and blocked the roadway, placing myself and others at significant risk. This failure presented an immediate threat to life and safety. I have since discovered that other Tesla owners have reported similar abrupt electrical or drive-unit shutdowns, suggesting this may represent a broader systemic defect. I am formally requesting that NHTSA investigate whether this issue meets the threshold for a safety recall and whether Tesla’s systems contain a defect capable of causing sudden, uncommanded shutdown while driving. Thank you for your prompt attention to this matter. I am prepared to provide all supporting documentation, including incident details, screenshots, timestamps, and service correspondence.

On December 2, 2025, my Tesla was charging in the garage of my residence in [xxx] , when a fire appears to have originated in or around the vehicle area. Before the fire, I smelled smoke/burning and also heard popping sounds. The fire spread rapidly and resulted in the destruction of my home, creating an immediate and severe risk to the safety of all occupants and anyone nearby. This incident exposed those present to danger from flames, smoke inhalation, toxic fumes, and structural collapse, and it caused emergency evacuation and displacement. The fire department identified the garage or vehicle area as the origin. The exact component or system that failed is unknown at this time, but the circumstances indicate a possible failure involving the vehicle, charging system, battery system, or related electrical components. I am not aware of any prior battery, charging, or electrical warning messages before the incident. Emergency responders and insurance representatives were involved after the fire. I previously attempted to notify Tesla of this incident, but I did not receive a response. Because this event involved a catastrophic fire and total residential loss, I believe it should be reviewed as a serious vehicle safety matter and that all relevant vehicle data, charging data, components, and related evidence should be preserved for inspection. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I parked my Tesla vehicle in a friend’s driveway. When I returned and opened the driver’s door, I entered the vehicle and attempted to put it into drive. At that point, the vehicle display went completely blank and the vehicle became inoperable. I then attempted to open the door from inside the vehicle, but the door would not open and I was unable to exit the car. I was effectively locked inside the vehicle. I contacted Tesla customer support and remained on the call for approximately 1. 5 hours before receiving assistance. Tesla customer support confirmed that the issue was caused by failure of the 12-volt battery. At the time of the incident, the outside temperature was below 0 degrees centigrade. The incident occurred in cedar rapids, iowa. There was no prior warning or notification from the vehicle or the Tesla mobile app indicating that the 12-volt battery was at risk of failure. The failure resulted in loss of vehicle function and inability to exit the vehicle, creating a serious safety concern.

I have repeatedly had electrical failure in the vehicle in the form of a "reduced power alert" which renders the vehicle with significant limitation to drivability. This places the vehicle in "limp mode" and this frequently occurs on the highway. Once this alert appears the vehicle has limited propulsion, limitations to steering and braking as well as other electrical systems. It has been to the dealership for repair on 4 occasions without remedy. It is leaving us on the highway in a dangerous situation repeatedly. It's not a one time event. There were 20 alerts showing on the screen when I limped it into the dealership once again on [xxx] having nearly wrecked on [xxx] just before the [xxx] exit. The reason this is so dangerous is the failures occur at higher speeds such as highway driving. Leaving one with an immediate loss of forward motion as if you've hit the brakes but vehicles behind you have no warning. This is going to end up with someone getting rear ended or worse. Social media indicates it is a prevalent and not well understood recurring problem. Tesla has been quietly repurchasing vehicles from angry owners. Dreadful.
