2013 Tesla Model S Electrical System Problems

While charging my 2013 Tesla Model S, the vehicle experienced a charging system failure and would no longer charge. Upon inspection, I discovered water intrusion and corrosion on the lower portion of the charging-related electronic circuit board at the bottom of the charging port and right where the High Voltage cables are located as well. The affected electronics are located in an area that is not normally exposed to water and is not owner-serviceable. Later model Tesla Model S vehicles (2014 and newer) include a 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.

On [XXX], at approximately [XXX], I was driving my 2013 Tesla Model S (VIN: [XXX] ) on [XXX] in Barrow County, Georgia when the instrument cluster/speedometer display went completely blank while driving. This is an intermittent issue that occurs without warning - the display turns off and sometimes freezes. Because the speedometer was not displaying, I had no way to know my actual speed. I was pulled over by Barrow County Sheriff’s Office and cited for speeding. I explained the 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)

The instrument panel went blank permanently posing a safety hazard due to loss of vehicle function status indicators such as speed, direction, gauges, warnings, and signaling.

November 20, 2025 To the National Highway Traffic Safety Administration (NHTSA) Office of Defects Investigation Subject: Safety Defect Complaint – Tesla Model S I am submitting this complaint regarding a serious and dangerous safety defect involving my Tesla Model S. Safety Defect Summary:    •   After the high-voltage battery failed, the vehicle would not enter Neutral.    •   I had to use Tow Mode in the middle of a street on a hill to avoid blocking traffic.    •   Once in Tow Mode, the car could not enter 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.

2013 Model S VIN [XXX] : 'Voltage sense open detected' poses shutdown risk on May 2021 replacement battery. Tesla claims 4-year warranty vs. standard 8-year; local service redirects without resolution. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The screen abruptly shuts down and that is a safety hazard. Tesla has refused to fix this issue.

Tesla instrument cluster screens are leaking fluid and eventually failing. The instrument cluster is the only place I can see my speed, thus my car is now unsafe as I can not tell what speed I am driving at.

The contact owns a 2013 Tesla Model S. The contact stated that while attempting to start the vehicle, the message “unable to drive, voltage supply” and “vehicle may not restart” was displayed. The vehicle failed to start. The vehicle was towed to the local service center who diagnosed that the drive unit was faulty and needed to be replaced, due to water ingress coming from the rear of the vehicle. The vehicle was not yet repaired. In addition, while operating the vehicle, a warning alert was displayed regarding the battery system and that the battery would no longer recharge. The vehicle was towed to the dealer who diagnosed that the HV battery pack had failed due to corrosion caused by condensation from the HVAC system. The HV battery was replaced, and the vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 95,000.

My main center computer touch screen has been leaking a sticky toxic glue for over 5 years. This toxic sticky glue continues to leak all over the interior of my vehicle which regularly needs to be cleaned. This saftey issue has been reported to Tesla several times and Tesla refuses to take responsibility for this saftey issue. The sticky toxic glue leaks severly worse when exposed to higher temperatures and definitely is related to heat/thermal heat exposure. Tesla did not utilize an automotive grade computer screen on earlier production vehicles and has since changed the type of computer screens utilized in their current production vehicles. This is an ongoing problems with thousands of earlier production vehicles. Tesla is aware of this problem and refuses take responsibility to issue a recall which affects thousands of customers who are experiencing this same saftey issue. Tesla WILL NOT help or do anything to resolve this problem saying my vehicle is out of warranty. I had to take the interior of my vehicle apart to constantly clean this leaking toxic sticky glue. This glue has been leaking on other interior electrical components which is a serious saftey issue!

Screen in front of the driver froze. Speedometer did not change, odometer did not change, map and directions did not change, gearshift indicator did not change, clock was frozen.

Last week, my vehicle could no longer charge fast and I am unable to charge past 107 miles. The following message appears: BMS_u029 / "Maximum battery charge level reduced" After researching the issue, I found that hundreds of other Tesla drivers have experienced this problem (see: https://teslamotorsclub.com/tmc/forums/model-s-battery-charging.109/). Some were unable to charge after receiving this message, and some were capped at 30-50 miles, making the vehicles practically unusable. Tesla charges $15,000 (remanufactured battery pack) to $25,000 (new) to fix the problem. But many drivers are reporting that the defect is caused by a Tesla design, where the AC condensation drips onto the battery pack and create rust and corrosion, which then cause the batteries to malfunction.

The touchscreen failed and I need it replaced, but Tesla says it’s not part of what the NTSB negotiated with Tesla to do regarding these screens. 2014 model S. It’s not fair to me to have to replace what I believe is a defect. Also, I believe this car was salvaged in another state and then brought to CA and resold to me. There was a salvage record on Bumper and now it disappeared. There’s also a code on my car that reads that acceleration may be reduced and Tesla wants to replace connectors but I keep getting more and more parts added to the quote. They say this is a “preemptive” repair. They made a new firmware/software rollout which took away my Sirius XM capability and they say they know about it, but won’t reinstall my software. I believe their software/firmware has taken away attributes on my car. Tesla won’t give me the repair history to the car and I fear they are hiding all the recalls saying they’ve been done when in reality they haven’t. I’m worried about driving the car.

As I was driving the vehicle home one night on the highway, the vehicle had a 13% charge and told me to pull over safely as it was shutting down. I had it towed to a charging station and the issue seemed to be resolved. Then after a couple weeks, I was driving on the highway and revived another warning, “maximum battery charge level reduced- ok to drive- schedule service.” I brought it to the nearest supercharger and it only charges to 24% charge and it charges extremely slow. I took it in for service and the told me I need to replace the high voltage battery and quoted me at $19,414. I have seen reports of investigations taking place currently in Canada for the same issue. Apparently, these older Teslas have an A/C condensor unit that dumps water onto the battery and causes battery problems. Please look into this for me as I believe a recall is warranted. Thanks so much! I also included the contact information of the dealership where my car is being serviced

Battery packs on older Model S are dying WHILE driving. Puts the car non responsive and limp mode. No choice but to try and pull over. No acceleration and car dies. First occurrence warning happened, however went away upon charging the vehicle. Drove to a Tesla service center under its own power, left service center under its own power with no warning messages. Tesla is aware of the issue with older battery packs, demands 20k or to scrap your car, or they require a legal release pertaining to the battery pack. I was locked out of my vehicle and it was held without a mechanics lein. This legal release absolves them of all responsibility over the vehicle especially if you bring it to another shop. Owners have no right to repair their vehicles at shops with certified technicians. The second time this happened, luckily the vehicle was parked and died in a driveway. No warning messages prior. Tesla says it gave warnings however I was not aware. Car was towed by AAA to a service center where it currently sits. Reference to another vehicle which received international attention for exact same issue. https://www.newsweek.com/man-says-tesla-locked-him-out-until-pays-26-thousand-dollar-battery-1743016 These older cars are not safe on the road.

Main LCD screen has cracked. This screen controls all aspects of the car. I was told by Tesla repair that the crack will start to discharge toxic fluid and the car will cease to function.

Electrical system power reduced warning. Vehicle shutting down.

Center LCD SCREEN bubbling and leaking fluid from panel into car.

Appointment for the Federal Recall NHTSA Recall No.: 21V-035 - 8gb embedded multimedia card (eMMC) VIN: FP24819 APPT. DATE: 24 MAY 2022 INCIDENT: Racial Profiling, Tesla customer service told the owner that he MUST PROVIDE THE 'PINK SLIP' (NOT THE REGISTRATION SLIP) FOR THE VEHICLE IN ORDER FOR ANY REPAIR OR SERVICE WOULD BE PROVIDED OR PERMITTED. This is racism, and not the first time.

Bubbles are developing on the instrument cluster screen that may pose a safety concern by obscuring sight of important vehicle information, including speed and battery charge status. This is getting worse (more bubbles developing and becoming larger in size) by the day. This is a known problem that has been reported by other owners. Please see the following links: https://teslamotorsclub.com/tmc/threads/bubble-on-instrument-cluster.91537/ https://teslamotorsclub.com/tmc/threads/instrument-cluster-bubble.192922/ https://www.reddit.com/r/TeslaLounge/comments/h049ur/air_bubbles_appeared_in_model_s_ic_screen_anyone/

I brought in the car to be parked as part of NHTSA Recall No. 21V-035. The "fix" provided has led to my center console in the Model S to shutdown completely. I contacted Tesla to inform them that their fix as part of the recall has actually led to more problems.
