What 365 owners told NHTSA about the 2014 Tesla Model S Bev

Agency: National Highway Traffic Safety Administration I am submitting a complaint regarding repeated denial of access to charging infrastructure for my electric vehicle due to fraudulent billing activity within Tesla’s Supercharger network. I own a 2014 Tesla Model S located in Alabama. My Tesla account has repeatedly recorded Supercharging sessions in California that were not performed by my vehicle. Tesla customer support representatives have acknowledged that this issue appears to involve VIN cloning or a flaw 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.

I am the current owner of a 2014 Tesla Model S equipped with MCU1. While driving, including at freeway speeds, the center touchscreen has rebooted unexpectedly, showing only the Tesla logo before recovering. During these reboots, critical vehicle functions are unavailable, including the rearview camera, HVAC/defrost controls, and other essential features. This failure matches the exact safety defect described in NHTSA Recall 21V-035 related to the MCU/eMMC failure. I reported this safety issue to Tesla Service and 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.

My [XXX] mother owns a 2014 Tesla Model S P85+ (VIN: [XXX] ) with only 50,367 miles. The vehicle suddenly became completely inoperable without warning. It would not turn on, would not charge, and the charge port would not open. The vehicle had to be towed. Tesla diagnosed failures of the high-voltage battery contactors, the onboard charger assembly, and HV circuit integrity. These are essential high-voltage components that should not fail at such low mileage. When these parts fail, the vehicle loses 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.

After a high-voltage junction box repair performed by Tesla, the vehicle shut down 15 miles after leaving the service center. Tesla replaced the high-voltage harness at no cost but provided no explanation. After the HV harness replacement, new proximity/sensor alerts began triggering that were not present before their HV work. Multiple reasonable diagnostic procedures were refused, including bench-testing the sensors. Tesla is pressuring me to take possession of the vehicle without providing written confirmation 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.

Overnight while plugged in and after the battery showed it was fully charged, the battery suddenly lost charge, and the car sent repeated alerts to immediately pull over and stop driving. A notice on the car showed mileage was reduced and to immediately schedule a service call. After returning home, I downloaded to the car a recent software update that cleared the error. However, after the software upgrade, Tesla messaged that they did removed tests and the high voltage battery must be replaced.

LCD dashboard is bubbling and liquid seems to be leaking within the dashboard screen. In some online research, there are concerns that contaminants can infilitrate the cabin when this happens. The problem seems to be pervasive for cars made by Tesla from 2012 to 2014. There were no warnings for when this problem ocurred. Tesla is saying that the part needs to be replaced at a cost of $1900.

Tesla has a Salvage Vehicle policy - when a vehicle has been branded as salvaged, regardless of future repairs, they will remotely disable the vehicle's ability to DC Fast Charge and require a DC System Inspection and DC Fast Charging Inspection at a cost of $870 that can only be performed by Tesla in order to service the vehicle and restore the DC Fast Charging feature. In my case Telsa has refused to perform the eMMC recall using the fact that I have not had the DC System Inspection service performed as their basis for refusing to perform the recall. Please seek an injunction against Tesla to ban them from using any pre-conditions such as first requiring a DC System Inspection in order to perform any recalls. Thank you.

My car has the Gen 1 master charger assembly which is the stock part. The part malfunctioned and is a well-known issue with this vehicle. Luckily, I was not placed in harm's way when the part failed but there are many of those that have no been so lucky. This failure is not caused by the operator but is caused by the faulty factory part. This is a $3,000 repair for the owner of the vehicle alone not counting the potential risk of harm to the operator. The manufacturer must know that there is an issue with this part due to them replacing it with the Gen 2 model.

The air conditioning system is also the battery management system for keeping the car at optimal operating temperatures. If this system fails then the car will shut down to protect the integrity of the batteries. I have had my car air conditioning system serviced four times and the front louvers that direct air flow continually fail. The service center has decided there is nothing they can do because the problem doesn't have a dedicated error code for them to address. However, when I supercharge the car and the car gets hot the louvers aren't functioning properly and the car will not charge. Once I let the car cool down and drive, if the louvers are still malfunctioning the car will reduce power to the point that I have to pull over on the freeway and allow the batteries to cool down. This has happened multiple times where I have to stop on the freeway because the car reduces power and won't drive. When I ask Tesla to look at the problem they say because there is no dedicated error code for this malfunction, nothing is wrong with the car and I should keep driving it.

My original eMMC failed and Tesla at first wanted to charge me to replace it. Then, online, I found out my car had the 8gb eMMC that Tesla was supposed to “voluntarily” replace. I told Tesla this and they agreed to replace it at no charge. The next day, my MCU failed. The car wouldn’t unlock, wake up, or connect to the Tesla App. The next day it woke up and drove fine. The following day, it wouldn’t wake up again. I had the car jumped and taken to Tesla. They now say the original MCU needs an “upgrade” and I have to pay about $3400 for it. From my understanding, the eMMC is part of the MCU. It seems the replaced eMMC won’t work with the original MCU. So-they voluntarily replaced a part that caused another part to fail. This seems like a scam rather than a fix.

In 2014, I ordered this Model S P85D, received it on 12/20/2014, I also purchased a 4-year extended service plan. Starting from March 2017, it started to encounter random yet serious problems. The car would randomly produce critical errors, displaying several types of error messages, while losing most of its driving power; the driver would have to perform emergency pullovers onto the road shoulder, if available, before the power rapidly reduce to zero. Then the driver need to restart the main computer (sometimes several times), to reset the error messages. Only after that, the car became drive-able again. I wrote an email to ServiceHelpNA@tesla.com on 03/23/2017 describing the problem, since then, this became a chronic issue; Service centers in Virginia, Maryland, and San Juan PR have performed numerous attempts on this problem, none of them was able to fix it. According to my records, for this issue, the car has been in the shop for more than 10 times, and more than a dozen components have been replaced. The total time it has been out of service is more than 380 days. I now consider it "unfixable" by Tesla. This kind of problem have created many dangerous situations when it occurred on the road, especially when the driver doesn't know how to handle it, doesn't pull over on the shoulder quickly, or there's no safe place to pull over.
