My vehicle intermittently and without warning disables Autopilot/cruise control while driving, most consistently during hard acceleration from a stop or low speed. The touchscreen displays "Take Over Immediately" and Autopilot becomes completely unavailable for the remainder of the drive. The system only resets after the vehicle is parked and allowed to sit. This has occurred repeatedly over multiple weeks, documented via the vehicle's own Service Mode diagnostic logs, showing the following recurring fault codes occurring together, dozens of times between approximatelyXXX and XXX: PM_w041_dasMIA – "Pedal Monitor Warning: DAS CAN node is missing" DI_w124_cruiseFault – "Drive Inverter Fault: Cruise faulted," user-facing message "Cruise control disabled" I brought the vehicle to a Tesla Service Center. Technicians stated they could not identify a specific cause, but acknowledged they were aware of similar cases from other owners of this vehicle model reported on Tesla's internal systems. No repair or resolution was offered. This vehicle is equipped with an HW3 (FSD Computer 3) Autopilot computer and Full Self-Driving Capability (purchased package). Tesla CEO [XXX] publicly confirmed on the company's Q1 2026 earnings call (XXX) that HW3 computers do not have sufficient capability for current and future Full Self-Driving software, and announced a remediation plan for affected owners. I have not been offered any remedy. I am concerned this represents a safety-relevant defect: the sudden, unpredictable loss of Autopilot/cruise control during active acceleration, particularly on-ramps or intersections, could create a hazardous situation for the driver and surrounding traffic.

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 X owners say
Most recent owner complaints, unedited.
While driving on FSD (Full Self Driving) the vehicle was turning off the road into a parking lot and sped up and hit a vehicle while I was pressing the brake to the floor! I had to brace for impact when I hit the vehicle. I have requested the data and telemetry logs from Tesla. Everything was fine before the crash. Husband had a similar incident a few weeks ago where he was turning with FSD engaged and the vehicle stopped in the middle of the turn with a vehicle coming right at him, he had the gas floored to get out of the way but was completely stopped, could not move for 15 seconds or so.
Tesla X in full self driving mode failed to lower speed and detect stopped in-lane vehicle on a very sharp turn, crashing into the back of the vehicle at significant speed.
I was driving down the road and my car started shaking, I was about 5 or 6 miles from an exit so continued and within 1 mile a rod broke and fell on top of my tire causing me to catastrophically have to stop n swerve off the road in 5 o'clock traffic. I just purchased this car 3 months ago, no issues just happend all of sudden. There are reports of weak suspension parts for tesla specifically the model x and y. The suspension parts need to be recalled. I was VERY lucky to not have collided with another car and potentially causing a fatality.
Our Tesla Model X is failing recently with several issues as listed below: 1. 'Autiopilot disabled' - Autopilot was not available to use since 09/2024 after upgraded to 12.x FSD upgrade. Tesla service diagnosed in 11/2024 with some error connected to evaporator fan, advised me to replace the kit at an estimated $580 2. 'Unable to start' - HV battery failed on 03/06/2025 with series of failures that was reported to the federal safety agency (VOQ#11651899). Tesla replaced the battery, and service delivered vehicle on 03/24/2025 3. 'Hood unlatch' failure - while driving home from Service center on the same day at 70 mph on I-95 freeway, the 'hood' popped up blocking the front view, and had to pull vehicle to shoulder to safety. There was NO warning message on the screen at all. Took the vehicle to service immediately, and service team pointed that they forgot to turn on 'auto-latch' resulting hood failure. They offered the 'free' repair of hood. 4. 'ECU Autopilot failure' - while taking the delivery of 'hood' fix on 04/22/2025, I noticed the 'autopilot' was still NOT working. Serviced diagnosed with 'failed autopilot ECU' at an estimated cost of $1791.55. Currenlty the vehicle is with Tesla Service team. My vehicle is with service team since 03/06/2025, and has been identified with series of issues/failures. It has caused severe safety failure putting our lives at risk with 'unlatched' hood while driving on a freeway. Also with HV battery failure its completely unreliable on when it might fail during driving. Now with failed autopilot ECU, we are unsure of the vehicles ability to navigate, drive function and safety concerns. Service team is unable to provide precise root causes or fixes, or restore it to a functioning vehicle. Every visit with service team there is a new issue with vehicle. Our family is greatly concern with the quality of the vehicle, persisting issues, safety concerns and overall reliability of the vehicle. Please find enclosed all service records.
Based on thousands of posts, replies, etc, this seems to be a well known issue with this model/year Tesla as well as other years/models. It seems that the Wheel Sensor Cable is not fastened properly, and over time, the cable runs against the tire, causing the internal wires to be exposed, this in turn causes numerous faults to occur, which includes causing ABS, lane departure avoidance, traction control, stability control, ABS, and regenerative braking to stop working. This happens while driving resulting in an immediate change in how the vehicle functions which could easily lead to a major accident While there are numerous forums where this issue is noted, below is one that details the issue with photos [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
‘safety restraint system issue’ error pops up when ever car is turned on was told that can cause airbag to not be deployed when needed.
While driving on highway with autopilot on . I received the message "Steering Assist reduced .Vehicle will require additional force to steer". I believe I hit a rough patch on the highway and my steering lost power and became very hard to steer the vehicle. Somehow I managed to drive for 20 miles to safety. When I recached home I did power reset few times and the issue went away. I noticed similar issues with model x but not for year 2018 Model x. I have opened a service request with Tesla .Tesla send me an invoice of $5500 for repair.
I was driving on [XXX] from Carson City to Reno in Washoe Valley while on autopilot, the car suddenly alerted with very loud alarms, showed 1. steering assist reduced, 2. Automatic Emergency Braking is unavailable 3. Traction Control disabled 4. Stability control disabled 5. Park Assist unavailable. I pulled over to a safe parking area. Then the car locked out for 75 mins, in Neutral gear, can't shut off, can't park, can't reset the car at all even after talking to Tesla support. While waiting for the tow truck, I turned it into Tow mode, was able to change into Park mode finally, and hard reset the car. I took it in and Tesla told me the steering system was the problem and I was out of warranty so I had to pay A LOT OF money to repair/replace it.

The vehicle was in cruise control and had a phantom braking event. The vehicle was going at 70 mph and suddenly braked even though there was significant distance between the car in front and nothing on the road. The sun was glaring on the road and possibly the car detected the shadow on the road as an object and braked because of it.
