2022 Tesla Model 3 driver assist problems

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

My 2022 Tesla Model 3 Long Range has developed a failure of the Autopilot/ADAS computer. The AP computer remains installed in the vehicle and is available for inspection. The vehicle operated normally before software update 2026.26.6. Following the update, Driving Visualization and Autopilot began going offline, along with automatic headlights, automatic turn signals, emergency braking, collision and traffic warnings. The failures have continued despite software/firmware reinstall, DAS reset, camera calibration, and hard reset. Tesla Service inspected the vehicle and confirmed that the AP computer is defective and recommended replacement at approximately $2,600. I paid $120 for Tesla's diagnostic assessment. Service Mode has recorded repeated AP watchdog/kernel-panic events, including APS_w169_TurboA_SCS_LKUP, APS_w134_appMIA, APS_w135_appCritical, and PM_a041_dasMIA. The vehicle has also recorded simultaneous exits of multiple camera streams, sometimes causing camera feeds to go black while driving. Service Mode has shown the AP ECU in Coreboot/INIT, intermittent loss of communication between the AP ECU and infotainment ECU, missing GNSS Ethernet communication, and unavailable AP temperature telemetry. This creates a safety concern because multiple safety-related driver-assistance and camera-dependent systems can unexpectedly become unavailable while driving. The vehicle remains manually drivable, but the driver must unexpectedly operate without previously available functions. The failure can also affect automatic headlights and turn signals, requiring manual operation. I am reporting this as a potential safety defect because multiple ADAS/camera systems fail simultaneously and the AP computer repeatedly crashes/reboots. The failure began after a software update, although Tesla has stated that some alerts predated the update. Due to the GPS board contacting the autopilot first before the infotainment, precise location is off and navigation is unavailable.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

With its latest upgrade, 2026.20.6.11 with full self-driving V14 Light, Tesla no longer allows users to set a max speed. This is very dangerous, especially in school zones where the vehicle, with Full Self-Driving, consistently misreads the speed limit. There is no way to revert this "upgrade." Many people have posted about this concern, but Tesla is ignoring it.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

The horn on the steering wheel rarely works UNLESS it is pressed directly in the middle. I have tried to honk the horn when there is a safety event but it rarely works. This is definitely a safety issue. This has been going on since I bought the car June 2022. Full self drive is also unsafe and it will make sudden turns, accelerate too quickly, or have phantom braking. This can be unsafe for other drivers. I heard that this is improved with newer models, but if it is unsafe for older models like my 2022, it should not be available.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Tesla software update 2026.20.6.11 v14 Lite NA-2025.44 removed manual speed control for Full Self-Driving. The driver can no longer set a maximum speed. The vehicle chooses its own speed and it is frequently wrong and dangerous. Curves are the worst failure. The car enters curves too fast. It accelerates through curves. It does not slow to a safe speed before the curve begins. The driver has no way to cap the speed. The scroll wheel is dead. There is no override. Posted speed limits are ignored. The vehicle uses bad map data instead of reading visible signs. It will do 65 in a 55. It will not slow down when the sign says 55. The driver cannot force it to obey the posted limit. Speed control is gone. The driver is a passenger watching the car make bad decisions. This is not safe. This is not driver assistance. This is loss of control. NHTSA must require Tesla to return manual speed control immediately. A human driver must be able to cap the speed at all times. The current software removes that ability and creates a clear safety hazard.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

On XXX, while Full Self-Driving (Supervised) was engaged, my 2022 Tesla Model 3 RWD abruptly decelerated without any visible vehicle, pedestrian, debris, or other obstacle requiring braking. Based on my best recollection, this occurred on approximately five separate occasions in clear daylight with clean cameras. On XXX, the first event occurred near XXX while traveling from [XXX] toward the [XXX]/[XXX] area. I took manual control for about 30 minutes. After I re-engaged FSD, a second event occurred and included approximately three rapid braking pulses. The occupants lunged forward during both episodes. On XXX, the drive from [XXX] to the Ukiah Costco was normal. On the return toward [XXX], FSD suddenly braked hard at approximately 63 mph and reduced the vehicle's speed by about 25 mph, to approximately 38 mph. Family members and friends in the vehicle were startled and moved forward. Later that day, there were two additional unexpected braking episodes while traveling from XXX toward XXX. I used accelerator input to override the unwanted braking. The unexpected highway-speed deceleration created a risk of being struck from behind and made the system unpredictable to supervise. No crash, fire, injury, or property damage occurred. I do not recall a warning message before the braking. The vehicle has not been inspected or diagnosed for this issue and is available for inspection upon request. As of XXX, the vehicle reports Tesla software 2026.20.3 and FSD (Supervised) v12.6.4; it has Hardware 3. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle was operating under Tesla Full Self-Driving (Supervised) on [XXX], on [XXX]. While FSD was engaged, the vehicle struck a large object/debris that was present in the travel lane. The system did not appear to detect or avoid the obstacle. The impact caused severe damage to two wheels and two tires, and the vehicle required towing. Tesla Service later confirmed that the damage was caused by road debris and replaced the damaged wheels and tires. I am submitting this report because I am concerned that the FSD system failed to identify or respond to a significant roadway hazard.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

I was driving my Tesla 3 back from LA yesterday. The car has "AI3" hardware not "AI4". The software is fully up to date. I do *not* subscribe to "Tesla FSD (Supervised)" but the car is equipped with "Autopilot". I was driving in "Autopilot" mode driving southeast on [XXX] between Eloy, Arizona and Marana, Arizona, on a clear freeway in bright daylight, at about [XXX] PT on [XXX]. The car suddenly slammed on the brakes for an emergency stop for no good reason. There was nothing in front of us. Fortunately it was clear behind me so no one slammed into us. We came to almost a complete stop. The "Autopilot" disengaged. I'm not sure why. I might have pressed the accelerator out of instinct to keep moving. During the incident a message in bright red briefly came up on the screen. I didn't get a chance to read it but I did catch the word "error" like some error in software was triggered. Once we got moving again and all was fine although my wife was in shock. I did not engage "Autopilot" again for the rest of the trip and I'm reticent to do so ever again.

I purchased the Full Self-Driving (FSD) package for approximately $10,000 on my 2022 Tesla Model 3 Long Range AWD. Tesla marketed FSD as a feature that would enable autonomous driving capabilities including Navigate on Autopilot, Auto Lane Change, Autopark, Summon, and city street driving - all to be delivered via software updates. Tesla has since confirmed my vehicle's HW3 (Hardware 3.0) computer cannot support FSD as advertised. There is no hardware upgrade path. The FSD Transfer Program that allowed owners to move their purchase to a new vehicle ended March 31, 2026 with no accommodation for affected owners. The system regularly fails to perform as advertised. It requires constant human supervision despite being sold as "Full Self-Driving." I have sent three formal complaints to Tesla's executive team (May 7, 8, and 12, 2026) with zero response. Tesla's own support chatbot confirmed I am not eligible for FSD transfer.

LANE DEPARTURE: ASSIST

While using Tesla's Full Self-Driving (Supervised) software on the Pacific Coast Highway (PCH) and other highways, the vehicle’s automated steering system repeatedly malfunctions by failing to maintain lane centering. Specifically, the car drifts or actively steers across double yellow lines into the lane of oncoming traffic. This issue is a persistent failure of the Advanced Driver Assistance System (ADAS) and Lane Keeping Assistance. The vehicle has attempted this maneuver multiple times at [Approximate Speed, e.g., 40-60 mph], requiring immediate and forceful manual steering intervention to avoid head-on collisions with oncoming vehicles. The system provides no warning chimes, error messages, or "Take Over Immediately" alerts prior to crossing the lines; it appears to perceive the oncoming lane as a valid path or fails to recognize the double yellow boundary entirely. This has occurred during [mention conditions: e.g., bright daylight with high glare / night time]. The vehicle is equipped with Hardware 3.0 (HW3). I believe the 1.2-megapixel camera suite or the processing power of the HW3 computer is insufficient to safely navigate the geometry of the PCH or any roads within mountains/hills. I have attempted to "Clear Calibration" and performed system resets, but the life-threatening behavior persists. The vehicle and its internal data logs are available for inspection. I have also sent "Bug Reports" via voice command to the manufacturer immediately following these near-miss events.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

All safety and driver-assistance systems on my 2022 Tesla Model 3 failed due to an internal short in the vehicle’s computer, as confirmed in writing by Tesla’s technician. All cameras (rear, side, front) are non-functional, navigation does not work, and all ADAS features (Autopilot, lane-keeping, collision warning, blind-spot monitoring, emergency braking, etc.) are disabled. The vehicle has no visibility when reversing and no active safety protections while driving. Tesla documented the cause as an internal computer failure, not related to damage or misuse. This creates a dangerous condition on public roads since the car loses all safety systems. Tesla quoted ~$2,900 for a new computer even though the failure involves critical safety components. This may indicate a broader safety defect.

The central computer in my 2022 Tesla Model 3 failed unexpectedly. This is a critical component that controls essential vehicle functions, including safety alerts, battery management, regenerative braking, Autopilot features, navigation, and over-the-air updates. The failure makes the vehicle unsafe to operate. The car is only 2–3 years old, and such a major systems failure in such a short time frame suggests a defect or premature failure in a component that is expected to last the life of the vehicle. Tesla has not offered a remedy despite this being a safety-critical system. I believe this failure presents a serious safety risk to myself and others on the road and should be investigated.

Tesla Model 3 while using the “FSD” or auto pilot mode will do what’s called “phantom breaking” with its emergency breaking system. This is very scary and has almost caused more accidents than preventing them in my experience. Tesla had not addressed or fixed this issue even with their constant software updates. How is this FSD considered legal I wonder.

Tesla M3 RWD 2022 - 79750k miles. Touchscreen keep restarting throughout the day , in the morning when I am backing out of the garage, while I am driving, while I parked. It is dangerous specially while I am backing out of garage, car will stop sometime, because whole system reboots. I have no visibility I have to wait till its finish restarting. Tesla's main computer handles everything in the car, A/C, Turn signals, speedometer, backup cameras, forward collision warning and many more necessary function of the car. Tesla service center diagnose stats "The cause was identified as kernel panics detected in the system. The internal memory of the car computer is corrupt and will not allow enough data transfer and causing the computer to reboot to clear space" They suggested to replace the computer and its a out of warranty fix, since I drove 79k miles. This is a crucial of the car and it should not fail in 3 years, driving 79k in California is not unusual, Tesla service also blamed that we didn't extended our warranty after 50k. We couldn't find any correspondence from Tesla on service app or email regrading warranty extension. $3000 to replace a computer is a very high price.
