2020 TESLA MODEL X Unknown Or Other Problems

I am a software engineer and owner of two 2020 Tesla Model X (Raven) vehicles. Both exhibit a serious safety defect after installing firmware 2025.44.25.4 with FSD v12.6.4. Vehicle configuration: Model S/X with MCU2 (Intel Atom) and Hardware 3 (HW3). Defect description: When Full Self-Driving (FSD) is engaged, the vehicle intermittently enters a critical failure state while in motion: • The instrument cluster (driver display) suddenly goes completely black • The center screen issues a red “Take Control Immediately” alert with alarms • The infotainment computer performs a watchdog reset and reboots (Tesla logo appears) while the vehicle is traveling at highway speeds This has occurred multiple times on both vehicles. Suspected cause: The 2025.44 software update appears to introduce additional dashcam telemetry writes (speed, steering, FSD state) to the USB device while recording video. On MCU2 (Intel Atom), this creates an I/O and CPU bottleneck that starves display and safety-critical threads, triggering an operating-system watchdog reboot. Disabling Dashcam immediately stops the crashes, indicating a resource-exhaustion condition rather than driver error. Safety risk: During the blackout and reboot, the driver loses all visual feedback from the instrument cluster while being instructed to take control. This creates a high risk of collision, especially at highway speeds or in complex traffic environments. Severity: Loss of driver display and system reboot while driving constitutes a safety-critical defect. This condition could lead to serious injury or death. I request NHTSA investigation into instrument-cluster blackouts and system reboots on Tesla HW3/MCU2 vehicles when FSD and Dashcam are enabled.

Since Tesla did a recent software upgrade for the autopilot, the car on a single carriageway drives very close to the right side, and fairly frequently drives over the white line on the right side (i.e. departing from the travel lane). The car used to sit in the center of the lane. The problem does not occur on the highway where it still travels in the center of the lane. The problem occurs when autopilot is used on [XXX] in New Hampshire, southbound from Wakefield to Rochester, NH. Autopilot has to be disengaged to correct the problem.

I was traveling from Texas to South Carolina and unfortunately decided to take my Model X, which was a bad idea to buy after the worst experience my family had gone thru. During my trip I stopped at supercharger in Cottondale, Alabama while my car was in starting My Model X broke and couldn’t start due to some technical problem with the car (car is still in factory warranty). The called road side assistance and was shipped to service center. 2/7 I am still lingering in middle way off my home or destination. I tried calling service center but no answer and mailbox is also full couldn’t leave voicemail. After trying multiple times (15-18times) finally I was able to speak with someone. 3/7 I was told by Service Super at Fayetteville, GA that car cannot be fixed and they have not started diagnosis and I have to wait for minimum 10days. I told him my situation that I am traveling with my 2 kids ( 6yr & 8yr) and as I am in middle of my trip and not at my home town. 4/7 It’s hard for me to keep waiting for the car and ask him he can help me get the car fixed on priority giving the situation I am in. The Supervisor was not able to arrive on any agreement. I also told him to get the car fixed and ship to Texas since the car was having mechanical 5/7 problem and under factory warranty. I didn’t expect the answer what I got from Tesla service center and was told no. It’s hard to believe that Tesla didn’t care about customer service and after paying such a huge price they don’t care about its product. 6/7 I wanted to bring to Tesla attention and wanted to get some resolution. I am still here with my family and 2 young kids in Atlanta waiting for my car far away from home with zero support from Tesla. #tesla 7/7

Continental Cross Contact LX Sport tire on my Tesla Model X delaminated at only 15,000 miles causing extensive damage.

The rear back doors will not open. The car's computer says an obstacle is detected however there is no obstacle in the way of the doors. (I have a video to prove my claim) the safety of my passengers in the rear seat are at risk as they can not exit the car through the rear door. I have had the vehicle inspected by the dealer (Tesla) however they said they can not recreate what has happened. The warning light "obstacle detected" appeared however there was no obstacle in the way. After rebooting the car's computer it still happened. I was able to drive the vehicle to another location and try the back doors and then they finally opened. I feel the back doors should open any time and any place when the car is in park.

Was pulling out of the Starbucks drive thru when the car accelerated quickly on it's own. The brakes also failed. The vehicle only stopped after hitting a tree and a light pole. Very dangerous situation as this occurred in the morning when Starbucks is busy. State Farm insurance is in possession of the car currently. We are awaiting their findings. Police report is also pending. I did not see a warning indicator on the car or any indications of any problems. However, the car had been serviced frequently for different issues with Tesla. After the accident, Tesla offered no assistance regarding finding out if there was a safety issue and said we were on our own.

Had failure of leaking coolant fluid in my Model X. First time occurred November 2021. Second time April 2022. Both times the 3&4 way values failed and started leaking fluid which disabled my vehicle. This is the 3rd time in 1 year that I’ve gotten the low Coolant leak warning. This is a real problem and I’m concerned since my warranty is running out soon. The 3&4 way value shouldn’t last less then 6 months.

Tires wear out only inside All 4

As I was slowly backing into a supercharging parking space watching the rear view video on the car's LCD screen, unbeknownst to me the image from the rear view camera froze. To me it appeared that the car had stopped moving so I applied a little more juice and promptly ran into the protective bollard at the back of the parking space, at which point the rear view camera started working again. If there had been someone behind me, I would have hit them. As it was, I only damaged the car's rear hatch. I tried backing up again and had the image freeze again. I then re-booted the car's system and the problem was not experienced again on that trip. Since then I have had the problem occur one other time and re-booting the system again seemed to fix it. The problem appears to be due to a failure in the car's software as it relates to the rear view camera. I have not taken the car to a dealer yet to see if they can fix the problem and the car has not been inspected by another party. There were no warnings or messages when the problem occurred.

Rear Passager Falcon Door does not consistently close on on the first attempt. Would need a second or multiple pressing of the button to close. The wing door scrapes the C- Pillar and is misaligned. Apparently, there is a flaw in the calibration and sensors. Every time I close the wing, I have to wait around to make sure it is completely closed. Frequently, the wing just gets stuck halfway and the passenger has to go over the side to exit or enter. The other door operates perfectly fine. This is unsafe because it makes it more difficult for passengers to get out of the car if the door refuses to open or close completely as it should. Have taken the vehicle to the service center and complained multiple times. Telsa simply says it operates within their standards, which is absurd. They suggest cutting the glass on the C Pillar to stop the scraping, and pay for it out of my own pocket even though it's still under warranty.

While on autopilot or cruise control, the car would suddenly and abruptly slam on the brakes for no reason. There's no traffic or objects to avoid. It was very startling because it could have caused a massive rear-end collision had I not intervened to cancel the autopilot and speed up again. . Because of this, I have stopped using the autopilot feature altogether. I cannot trust it will work properly. I have mentioned it to Tesla and they simply say the software update will solve it. It has not!

Around 1:50 P.M May 27, 2021, I left my house driving my Tesla 2020 Model X with my son in the front passenger seat to his school. We returned to our home around 2:19 P.M. At our front gate, I slowed down to a close stop as I turned the vehicle into my driveway. Once descending the driveway, my Tesla vehicle suddenly accelerated to an extremely high speed. While I attempted to brake; however, none of the speed controls seemed to work. The vehicle hit my 2009 Toyota Camry parked on the left side of my driveway first, then took out the heavy duty wrought iron fence post and gate door located about 100 ft from my front gate. My Tesla vehicle kept moving at a very high speed and knocked down and damaged all trees, plants, and garden arbors along the vehicle’s path and, then, crashed through the rear wrought iron fences about 200 ft from my front gate. Finally, the vehicle stopped after crashing into two large trees and stop there. My son got injured and was taken to an urgent care facility after the crash. Two of my vehicles including 2020 Tesla Model X and 2009 Camry LE were totaled and a large portion of my backyard, fence and gate were destroyed due to this Tesla crash. This Tesla vehicle suddenly accelerated for no reason, indicating that there must have been something seriously wrong with this vehicle at that time. The resulting skid marks on my driveway discovered after the incident demonstrates that braking was applied even though the vehicle accelerated. I had reported this crash to Tesla on May 27 and followed up on May 29, June 1 and June 3 and have not received a response from Tesla at this time. The investigation shall be performed to find why this Tesla vehicle suddenly accelerated to prevent other Tesla vehicle drivers from similar dangerous incidents caused by the vehicle’s sudden accelerations. I have the videos and photos from the crash. Please let me know should you need this information for the investigation.

Sudden forward unintened rapid acceleration resulting in personal injury and property damage

WHILE DRIVING AT HIGHWAY SPEEDS, MY TWO INFO SCREENS THAT PROVIDE ALL FEEDBACK TO THE DRIVER (E.G., SPEED, WARNING LIGHTS, ETC.) GO DARK. THIS HAS HAPPENED ON MULTIPLE OCCASIONS AND I HAVE DOCUMENTED WITH TESLA. THEY ACKNOWLEDGED THE ISSUE AND SAID THEY ARE WORKING ON A FIX(?)

Mileage: 6,000

NEW SOFTWARE UPDATE HAS MADE THE FONT OF THE DISPLAY TOO SMALL TO READ SO THE DRIVER CAN NO LONGER SEE WHAT GEAR HAS BEEN SELECTED LIKE DRIVE, PARK, NEUTRAL OR RESERVE. THE FONT IS SMALLER THAN THE AVERAGE PERSON OVER THE AGE OF 42 CAN READ IF THEY HAVE ANY DEGREE OF PRESBYOPIA.

THE INSTRUMENT CLUSTER DOES NOT SHOW A VALID SPEED. SPEED IS SHOWN AS '0' EVEN WHEN VEHICLES IS TRAVELING AND EVEN WHEN CRUISE CONTROL OR 'AUTO PILOT' IS DRIVING.

I WAS DRIVING ON FREEWAY 99 NEAR CHOWCILLA, CALIFORNIA IN MY TESLA MODEL X WITH UNDER 7,000 MILES ON AUTOPILOT AND THERE WAS NO CARS IN ANY DIRECTION NEAR ME. THIS FREEWAY WAS A STRAIGHT LINE WITH NO BENDS OR CURVES. THE CAR WAS TRAVELING AT 75 MPH IN THE MIDDLE LANE ON AUTOPILOT AND THE CAR SUDDENLY DECELERATE VERY AGGRESSIVELY FOR NO REASON. THE TIRES SCREECHED AS THE CAR'S SPEED SUDDENLY CAME TO A NEAR STANDSTILL AT THE SPEED OF 10-15 MPH. THE DRIVER ([XXX]) TOOK MANUAL CONTROL AND DROVE THE CAR WITHOUT ANY POTENTIAL FATALITIES. IF THERE WAS A CAR OR TRUCK BEHIND US, WE WOULD HAVE DIED. THIS HAS HAPPENED ON TWO PREVIOUS OCCASIONS, BUT THE DECELERATION WAS NOT AS SUDDEN AS THIS LIFE THREATENING OCCURRENCE.
