Loss of rearview camera
On November 20, 2020, the Office of Defects Investigation (ODI) opened Engineering Analysis (EA) 20-003 to investigate incidents of media control unit (MCU) failures resulting in loss of rearview camera in model year (MY) 2012-18 Tesla Model S and model year (MY) 2016-2018 Tesla Model X vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device. During its investigation, ODI learned that the expected usage life rating for the 8GB eMMC NAND flash memory device is approximately 3,000 “P/E” or Program-Erase cycles, after which the eMMC NAND flash memory device would become fully consumed and no longer be operational, leading to a failure of the media control unit (MCU). At a daily cycle usage rate of 1.4 per block, accumulation of 3,000 P/E cycles would take only 5-6 years. Historically, the expected life of a vehicle generally far exceeds 5-6 years of service. ODI believes that a 5- or 6-year life expectancy for a component integral to providing the driver with safety functions is insufficient. During our review of the data, Tesla provided confirmation that all units will inevitably fail given the memory device’s finite storage capacity. Tesla provided its own statistical model showing the number of projected weekly MCU repairs from 2020 to 2028, estimating that replacement rates for MCU failures will peak in early 2022 and gradually decline until (near) full part turnover has been accomplished in 2028. According to Tesla, for subject vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device, the eMMC NAND cell hardware will fail when reaching lifetime wear, for which the eMMC controller has no available memory blocks necessary to recover. With this failure mode, the only recovery available is a replacement of the eMMC device, achieved by physical part replacement of either the MCU assembly or visual control module subcomponent. Tesla provided information concerning the effects of MCU failure on vehicle function, which include in loss of rearview/backup camera and loss of HVAC (defogging and defrosting) setting controls (if the HVAC status was OFF status prior to failure). The failure also affects the Autopilot advanced driver assistance system (ADAS) and turn signal functionality due to the possible loss of audible chimes, driver sensing, and alerts associated with these vehicle functions. Based on this analysis, ODI issued a Recall Request Letter (RRL) on January 13, 2021. The RRL was based on ODI’s tentative conclusion that a defect related to motor vehicle safety exists in the subject vehicles because the eMMC NAND flash devices have a finite lifespan based upon the number of program/erase (P/E) cycles, after which the MCU fails due to memory wear-out, which constitutes a premature failure of safety-critical part. Tesla responded to the Recall Request Letter (RRL) on January 27, 2021, and disputed the tentative findings of the RRL. Nevertheless, on January 29, 2021, Tesla filed a safety recall (21V‑035), recalling (MY) 2012-2018 Tesla Model S and (MY) 2016-2018 Model X vehicles with a center display equipped with a NVIDIA Tegra 3 processor and an 8GB eMMC NAND flash memory device. In this recall, Tesla is providing a free hardware remedy in addition to the over-the-air (“OTA”) firmware updates that the company had previously implemented. the federal safety agency will continue to monitor the issue as part of its ordinary processes for overseeing the effectiveness of recalls. However, based on available information, at this time, Tesla’s recall appears to address the unreasonable risk to motor safety presented by the premature failure of the component. Accordingly, the investigation is closed. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to

Loss of rearview camera
On June 22, 2020, the Office of Defects Investigations (ODI) opened Preliminary Evaluation PE20-010 to investigate incidents of media control unit (MCU) failures resulting in loss of rearview camera in model year (MY) 2012-2015 Tesla Model S vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device. EMMC NAND flash devices have a finite lifespan based upon the number of program/erase (P/E) cycles. The subject MCU allegedly fails prematurely due to memory wear-out of the eMMC NAND flash. Tesla used the same MCU with the Tegra 3 processor in approximately 159 thousand 2012-2018 Model S and 2016-2018 Model X vehicles built by Tesla through early-2018. In response to ODI's Information Request (IR) for PE20-010, Tesla provided ODI with 2,399 complaints and field reports, 7,777 warranty claims, and 4,746 non-warranty claims related to MCU replacements. The data show failure rates over 30 percent in certain build months and accelerating failure trends after 3 to 4 years-in-service.According to Tesla, for subject vehicles equipped with the NVIDIA Tegra 3 processor with an integrated 8GB eMMC NAND flash memory device, the eMMC NAND cell hardware can fail when reaching lifetime wear, for which the eMMC controller has no available blocks to recover. With this failure mode, the only recovery available is a replacement of the eMMC device, achieved by physical part replacement of either the MCU assembly or visual control module subcomponent. Tesla provided the effects of MCU failure on vehicle function which result in loss of rearview/backup camera, loss of HVAC (defogging) setting controls (if the HVAC status was OFF status prior to failure.) There is also an impact on the advanced driver assistance support (ADAS) Autopilot system, and turn signal functionality due to the possible loss of audible chimes, driver sensing, and alerts associated with these vehicle functions. There are precedents for addressing defects that result in loss of either backup camera, defogging, or turn signal functions under safety recalls.Tesla has implemented certain Over-The-Air or OTA updates to subject vehicles to mitigate the effects of MCU failure. These updates include firmware changes to reduce memory usage of the subject memory card, improve eMMC error correction and storage management strategies, changing the control logic for turn signal activation, and defaulting the HVAC system to Auto (71.6F) for drives after MCU failure to address windshield defogging. Tesla indicated that the MCU failures are likely to continue to occur in subject vehicles as vehicles continue to operate and use available memory in the 8GB eMMC NAND flash memory until 100% of units have failed. This investigation has been upgraded to an Engineering Analysis (EA20-003). The VOQs associated with the upgrade of this investigation are identified in the attachment to this resume.

What 2018 Tesla Model S owners say
Most recent owner complaints, unedited.
Car was in summon mode and crashed into a fence . Caused damage to frond end of the car
Recently right side blind spot monitor camera stopped working. As result, majority of safety features in vehicle has been disabled to include forward collision warning, adaptive cruise control, and many other safety features of the vehicle.
both vehicle displays have stopped functioning, therefore there is no indication of speed, remaining charge, blind spot protection, or back up camera. also, turn signals are non-functional. This is a safety concern to yourself and other drivers.
On [XXX], my 2018 Tesla Model S (VIN [XXX] ) experienced a complete brake system failure while in motion. The brake pedal was pressed multiple times, but the vehicle did not stop, resulting in a collision. The emergency brake also failed to engage. 1. Component/System Failure: The braking system, including both the standard hydraulic brakes and the electronic emergency brake, failed to operate. The vehicle is available for inspection upon request. 2. Safety Risk: This put my safety and the safety of others at immediate risk, as I was unable to stop the vehicle to avoid an accident. 3. Confirmation of Problem: The problem has not yet been reproduced or confirmed by a Tesla service center since the accident, but the vehicle previously had recalls in 2021 and January 2024 for brake and emergency brake issues that Tesla claimed to have remedied. 4. Inspection: The vehicle has been involved in an accident and has been documented by police and insurance representatives. Tesla has not yet inspected the car after the most recent failure. 5. Warning Lamps/Messages: There were no warning lamps or error messages on the dashboard prior to the failure. The brakes appeared normal until the moment they failed completely. This incident demonstrates that the recall-related brake defects remain unresolved and present a serious safety hazard. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
In July 2024 all the cameras on the Tesla Model S except the rear stopped working after a failed software update. This meant that all of the driver assistance systems as well as GPS, adaptive cruise control, blind spot monitoring, lane departure warning, forward collision warning etc stopped working. The lack of availability of this system meant that the car no longer had any advanced safety features that came with the car. It took many months for Tesla service to diagnose and fix the problem, which they identified as a failure of the Auto Pilot computer. After I was finally able to get an appointment with the Service center, they replaced the Autopilot computer at a cost of over $1500. The failure first appeared in July 2024. The symptom was GPS location being stuck and Autopilot and all safety features being not available.
While driving both North (in the evening) and also South (in the morning) on [XXX] between Washington, DC and Richmond, VA I have experienced an issue with Tesla’s Auto Pilot that can be very dangerous and scary. While using the navigation system and with Auto Pilot on while in the left most line on this divided highway, the car made multiple attempts to steer into the Express Lanes even when the large gates are closed and the red lights are on to indicate that the Express lanes are closed in the direction of traffic. To counteract this, it is necessary to quickly take control of the steering wheel and to get it to cancel Auto Pilot, otherwise the car would go into the gates and cause an accident. This has happened to me several times when I was traveling in the left most lane and when the gates were closed. This happened in November, December and in January. The system has not learned to handle this situation and to avoid steering into the barriers. I reported these incidents to Tesla’s Support Team by phone and after several weeks I received a phone call whereby the local service center (Rockville, MD) called me. Josh, the person that called me read a lengthy text to me that essentially reviewed the driver’s responsibilities when using Auto Pilot. I asked if there was any indication that they will work on fixing this issue and I was told that the explanation I got (which was no explanation at all, just a reminder of driver responsibilities) was the entire response. I informed him that I would report the incident to the federal safety agency. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
While driving in Autopilot mode, approx 70 mph in light rain the vhicle began to drift side to side almost crossing over the lane dividing line. Upon grabbing the wheel to take control the vehicle entered multiple 360 degree spins crashing into "K" rail. In the past I have noticed when taking control of the vehicle from Autopilot the wheel jerks.
My car was left on the driveway for a weekend where I was out of town. Upon returning, as I got into the vehicle and started reversing to get out of my driveway; several alerts popped up on my car. The alerts included "Steering assist reduced", "Stability control disabled", "Automatic emergency braking unavailable" and lastly, "Parking brake Fault." Immediately the power steering was gone and it took several pounds of force to turn the steering wheel even a little bit. Then, the parking brake engaged. No matter how many times I put the car into Drive, it would engage the brake again. My vehicle was halfway out of the driveway and into the road and I was causing my neighbors angst. After several reboots, it still was not working. I was unable to even get the car into neutral to push the car back on to my property and out of the street. After nearly 20 minutes of trying and almost giving up; the parking brake disengaged for a few minutes and allowed me to get back to the driveway. However, when driving the brakes were extremely loud when the car was in motion. The car was completely fine with no signs of wear and tear or issues prior to the out of town weekend. The car was also fully charged so to not run into any batter issues upon my return. After some internet sleuthing, this issue is decently common and is caused by faulty housing in the steering rack. The nuts/bolts that were used by the manufacturer could not withstand more than a few years of wear and tear. I believe there was a recall on the previous years for this exact situation. I am afraid I will have to take it to Tesla service and pay several thousand dollars as the warranty expired last year.
Received and error message, Lane Departure Avoidance features unavailable and steering assist reduced simultaneously while driving between 65-75 mph. Steering will required extreme effort to turn. I was about 5 minutes from home exited the highway and took the backroads. Steering did require extreme effort. The following morning, car worked fine.
