2016 Tesla Model S Electrical System Problems

I am writing to formally report a recall-related safety defect that occurred after the eMMC recall service on my vehicle’s Media Control Unit (MCU). Following the recall, the display adhesive began to leak and the screen started separating from its frame. The adhesive continues to drip onto the dashboard and the display shows signs of delamination. This is a safety issue that directly affects driver visibility and may result in electrical contamination inside the MCU. Under federal law, Tesla is required to correct any defect that is related to or arises from a recalled component. This obligation is clearly stated in 49 U.S. Code Section 30120 and 49 CFR Section 573.6. The adhesive leakage and display delamination meet the definition of a related safety defect under 49 CFR Section 573.5(c) because the problem is connected to the same system that was recalled and repaired. A manufacturer performing a recall repair must return the system to safe operating condition. Tesla is therefore responsible for verifying and correcting any new or worsening safety defect identified during or after recall service. Tesla’s own internal Service Bulletin SB-21-17-003 confirms this obligation. It states that if display delamination, bubbling, or adhesive leakage is observed, the entire MCU assembly must be replaced. The service department’s statement that Tesla is “not obligated” to inspect or replace the screen is incorrect and contradicts both federal recall requirements and Tesla’s own technical documentation.

The center touchscreen in my Tesla Model S developed a yellow discoloration and later began leaking a sticky fluid from the edges of the display. This fluid appears to be seeping from inside the screen and emits a noticeable odor. The touchscreen is the primary interface for controlling most of the vehicle’s safety-critical systems, including the backup camera, gear selection, climate control, lights, and driver assistance settings. The leak causes visible streaking and distortion on the display. This directly impacts the rearview camera feed — making it harder to see obstacles or pedestrians when reversing — which is a federally mandated safety feature under FMVSS 111. The problem worsens in hot weather and may result in fluid dripping onto electronics below, creating an electrical hazard or sudden display failure while driving. This appears to be a known design flaw in which the adhesive or seal inside the display fails over time. The issue can impair visibility of safety alerts, rearview camera images, and vehicle status, posing a significant safety risk to occupants and others.

While the car is parked and locked the rear driver side door opens in its own. The door handle does not present itself and is scheduled for repair. This is new and started happening today. Despite how many times I close it. It opens on it own. The door is locked when this happens. Door sitting still. Plugged in to charge and locked. The door opens on its own. It unlatches, Does not fully open.

The contact owns a 2016 Tesla Model S. The contact stated while attempting to park the vehicle, the brake pedal was depressed and failed to respond. There were no warning lights illuminated. The contact depressed the brake and the vehicle kept rolling forward. The contact opened the door for the vehicle to come to a stop. On another occasion, the contact stated that the ADAS feature engaged and while driving at various speeds, and the vehicle failed to recognize stop signs, traffic lights, or pedestrians. The contact stated that the function was a paid feature; however, the system failed to operate as designed. On another occasion, the contact stated that the steering will shift to one side while driving at various speeds, and the vehicle became difficult to steer. The vehicle was not taken to the dealer to be diagnosed or repaired. The dealer was made aware, and the contact had a pending appointment scheduled. The manufacturer was not made aware of the failure. The failure mileage was approximately 79,000.

Component Failure: The Tesla NEMA 14-50 charging adapter for my 2016 Model S malfunctioned, causing overheating that melted a prong and led to an electrical fire. The defective adapter appears identical to those in Tesla's November 2016 recall, though mine was designated "not affected." The damaged adapter and charging cable are available for inspection. Safety Risk: This malfunction created a serious fire hazard endangering myself and my property. The electrical fire damaged both my vehicle and charging equipment, and the fire could have spread to my home, potentially endangering my family and neighbors. Verification: I took the damaged adapter to the Tesla Service Center in Colorado Springs, where technicians acknowledged the damage but refused to replace it under the recall. They visually confirmed the melted prong and fire damage. Manufacturer Response: After the incident, I contacted Tesla Corporate requesting replacement of the defective equipment. They responded that they don't believe the electrical fire was caused by the defective plug, despite physical evidence showing the same issue as recalled units. Warning Signs: Prior to failure, I noticed intermittent charging interruptions and the adapter becoming unusually hot. These symptoms began approximately three weeks before the fire incident. There were no dashboard warnings about potential charging equipment issues.

The contact owns a 2016 Tesla Model S. The contact received notification of NHTSA Campaign Number: 23V838000 (Electrical System) however, the part to do the recall repair was not yet available. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Received and OTA notice on the dashboard that states "Battery Fuse replacement" is required. The fuse is due to a Li-ion battery that wears out for a safety system. Life expectancy of the battery is 10 years. It has not lasted 8 full years. This is stated as a safety issue and Tesla has since redesigned this item to not required the batteries. I have alerted Tesla about this issue, have not had a reply, as yet. The vehicle can be operated without this safety device, which seems inappropriate. I feel this should be replaced under warranty and/or recall - but it appears Tesla will want to charge an excessive amount of money.

The contact owns a 2016 Tesla Model S. The contact stated that while driving at undisclosed speeds, the instrument cluster became inoperable on several occasions. The contact stated that the failure had occurred several times. The vehicle was taken to the dealer; however, the contact was informed that the failure would reoccur unless the vehicle was updated with a new infotainment center and a faster processor. In addition, the contact stated that the vehicle had been taken to the dealer several times due to the failure. The contact stated that recently the instrument cluster and the ECM were replaced. In addition, the vehicle recently received a software update. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 73,000.

Sudden unintended acceleration appeared to cause the Tesla while parking the car on the street in front of home accelerate go out of control and crash into the home totaling the car and damaging the house. Two days prior the vehicle was brought into a Tesla service location where Tesla replaced the 12 volt battery that they believed was causing the car not to power on properly at that time. After the crash and googling to see if others suffered similar issues it appears the NHTSA recently reopened a review of sudden unintended acceleration and this incident seems to align with concerns of the petitioner [XXX] . The police filed a report and it’s at the towing place where the insurer Allstate is going to evaluate the car for a total loss.

Dear NHTSA, I am writing to file a complaint regarding a SUA incident that occurred on October 20, 2023, involving my 2016 Tesla Model S. On the day of the incident, I pulled into my garage and began to park my car. When I pressed the brake pedal, the car suddenly accelerated forward, crashing into the garage wall and totaling the vehicle. The garage wall was severely damaged and will need to be rebuilt. This is not the first time that my Tesla has experienced SUA. In 2017, I filed a complaint with NHTSA regarding a similar incident. In my previous complaint (issue # 11000097 dated June 19, 2017), I described a similar incident that occurred in December 2016. At the time, Tesla denied that the incident was caused by SUA and no further action was taken. I am convinced that the SUA incident on October 25, 2023, was caused by a defect in my Tesla Model S. I am also concerned that other Tesla owners may be at risk of similar incidents. I urge NHTSA to investigate this matter and take appropriate action to protect consumers. I believe that Tesla should be held liable for the damages to my vehicle and my garage wall, and that the company should be required to recall all Tesla Model S vehicles that are at risk of SUA. Thank you for your time and consideration. Sincerely,

At 22 degrees fahrenheit, the vehicles cabin heat shut off after hearing a noise. The Noise appeared to be a broken cabin heating element. The window screen quickly fogged, and water began attaching to the outside of the windscreen, building up as ice. The windscreen was completely almost blocked. This problem has appeared common in my online research. I was informed by a non manufacture repair business that the issue became apparent during the low temperature cold weather in December 2022. The vehicle will be inspected by the manufacture. No warnings, alerts, or service indicators were show. The vehicle is still showing proper operation.

The main display in the vehicle is leaking very sticky hazardous fluid. Sometimes display goes out, sticky fingers make screen issues worse when so many controls are handled electronically. Tesla refuses to correct issue without spending $2000+ with dealer. This started 3 years ago. Leaking fluid on LCD is both main display and driver heads up dashboard. Huge safety issue with sun reflects on the bubble portions. Hard to read.

CPU compatibility to existing OS and memory system causing multiple failures during driving with: 1. instrument cluster reset or reboot (temporarily disables all controls related to buttons/knobs on steering wheel and possibly other safety functions), 2. main nav/computer screen reset or reboot (temporarily disables all controls), 3. auto braking activation (cannot be disabled by user) enabled at dangerous and unpredictable times of city traffic, 4. backup camera picture not updating/frozen during backing uo vehicle, creating illusion of: a. not moving when in reverse while driving, b. not showing objects that may be directly behind vehicle when in reverse Manufacturer (Tesla) service ticket opened and closed as “resolved with memory reset” without follow-up if problems still occur

The contact owns a 2016 Tesla Model S. The contact stated that over time, the adhesive for both the forward display and center console had degraded to the point that both components were able to move freely. The contact stated that the center console eventually lost electrical power, and as a result, the contact lost control and visibility of important vehicle safety features and information. The vehicle was taken to the dealer, who was unable to provide a specific diagnosis, but the vehicle was repaired after replacing the forward display and center console. The manufacturer was not notified of the failure. The failure mileage was 58,000. The VIN was invalid.

I took my car in for the tesla video card replacement voluntary recall. After the "repair," my display screen acts erratically and visually becomes distractive. So far the service centers are trying to UPSELL me a new system to replace the current "repaired" system for $1500. I have had no luck with them taking responsibility for this issue. The big screen flickers the navigation screen and also distorts the items on the screen. As of yet, they keep saying this is normal function/behavior and all I have been asking is to have the screen operate as it is intended. (which it was prior to the chip update). Also, I believe the issue is also affecting the audio in the car.....at times the sound has become distorted and think that sound is absent from the turn signals. I know the audio system must have been impacted by their "repair" because initially the system sounded twice as clear than before the chip upgrade.

While on the road/highway, the screen goes blank and soon starts rebooting itself. This is a big distraction and a matter of anxiety for the driver who fears sudden stopping of the car till the screen comes back up in a few minutes. This has happened to me intermittently many times. I have reported it several times but nothing was done since the technician at Tesla couldn’t repeat it the one time they may have test driven the car. That is the problem with intermittent issues. But for me, that one more time it happens next time, and I get anxious and distracted, it may result in an accident. I think this is a serious safety issues that many other Tesla owners have reported as seen on the web. Since your form asks for one specific date of incident I have indicated one approximate date but this has happened several times over last three years.

My Tesla is under a recall for bad memory. My Tesla constantly reboots. I often have to wait several minutes from when I get in the car until it is ready to drive with all functions. I sometimes am forced to drive with the center screen not working. This takes away my backup camera. A required safety feature. Tesla says the part is not available. I request a reliable loaner until they get the part repaired under recall.

A heater which warms the large battery which powers Tesla's EVs burned out while I was charging my vehicle at a Tesla supercharger. It appears to have been caused by a high voltage 'short' from moisture. I was able to continue driving the vehicle for over 100 miles, but did not have 'regenerative' braking. This made the stopping distance much longer - nearly causing a collision. When I stopped at another Tesla supercharger the car would not charge and had to be towed. This defect should warrant a recall.

2 problems: 1.) the eMMC chip for the screen has not yet been replaced due to supply issue? 2.) the battery heater stopped working causing driving ability issues. This should be a recall. the car lost both acceleration and braking power and made it dangerous to drive. I was unable to charge the battery, and had to have the car towed a long distance, costing me over $1,000 to have repaired.

The doors on my Tesla are electronic from the inside and outside. Sometimes the car will not let me out or in, especially in the rear drivers side door where the kids are. It will not open the door and presents a huge safety issue. My sons was trapped in the door previously and we couldn't get the door to open - it took about 5 cycles of locking and unlocking the car for the doors electronic door handle to finally allow the door to be opened Recently there was a lawsuit for a similar issue in which a man became trapped inside a Tesla and died of smoke inhalation because the doors would not open and first responders couldn't get in the car either. I contacted Tesla, who was able to diagnose my car and create a repair estimate for the malfunctioning door handles without even looking at the car because the problem is so widespread and well known. They want $700 to repair my door handles that are locking me and the kids inside the car but i don't have money to repair right now.
