2022 Tesla Model Y driver assist problems

LANE DEPARTURE: ASSIST

On 8/22/2026, my 2022 Tesla Model Y Long Range with approximately 81,000 miles developed an Electronic Power Assisted Steering (EPAS) fault immediately after I felt a brief jerk while reversing. The vehicle displayed “Steering assist reduced / Steering may require increased effort.” Manual steering currently feels normal, but Full Self-Driving/Autosteer and Lane Departure/Lane Keeping functions became unavailable. Tesla Service Mode shows repeated faults EPAS3P_a072_motFeedFwdError, EPAS3P_a049_piCtrlError, and UI_a020_SteeringReduced. For EPAS3P_a072, Tesla’s diagnostic screen describes a “Motor control feed-forward correlation error,” lists the potential impact as “Reduced steering assist and EAC inhibited,” and specifically lists “Replace EPAS” as the clear condition. The faults return after vehicle power-off and reboot. The vehicle was updated to software 2026.21.6 / FSD v14 Lite approximately two weeks before this occurred. There were no previous steering warnings. I am not claiming the update caused the failure, but I believe the timing warrants investigation. NHTSA Complaint 11749826 describes a 2021 Model Y with the same EPAS3P_a072 and UI_a020 faults, including Tesla Service Mode stating “Replace EPAS.” Complaint 11758026 describes another 2021 Model Y steering gear failure and requests expansion of Recall 25V-092 to earlier Model Ys. My vehicle has not yet been physically inspected by Tesla. The vehicle and diagnostic information are available for inspection. I request NHTSA investigate whether this EPAS failure extends beyond the current recall population and whether recent software changes may be contributing.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

The Autopilot/FSD computer (driver-assistance ECU) on my 2021 Model Y (HW3) began failing intermittently on August 2, 2026, days after installing a software update -FSD v14 "Lite" branch. The component is in the vehicle and available for inspection. While driving at highway speed in high ambient temperatures (112–125°F), the system repeatedly disengaged with "Cruise control unavailable" (alert DI_a175) and "System error — take over immediately" warnings, and later alert APP_w46u on FSD engagement. Failures included: FSD and Autosteer aborting within seconds of engagement or disappearing from the menu entirely; complete loss of driving visualizations (no lane lines or vehicle overlays); rear camera blacking out; loss of speed-limit recognition and automatic turn-signal cancel. Both FSD and Autosteer Beta failed identically, indicating the fault is in the shared Autopilot computer/camera pipeline, not one feature. Because the same camera/compute stack supports automatic emergency braking, forward-collision warning, and blind-spot warning, the status of those safety systems during the failures is UNKNOWN — I had to complete long desert highway stretches fully manually, with repeated unrequested hand-backs of control creating a sudden-takeover risk. The fault is thermal-load related and intermittent: it recurred at high ambient temperatures, sometimes recovered after a rest or power-off reset, but on August 4 one full power-off reset at 88°F ambient failed to restore the system (it later self-recovered), suggesting progressive hardware degradation rather than ambient heat alone. Not yet reproduced by a service center: a Tesla service appointment is scheduled for August 13, 2026, and a service request with fault codes was filed in-app while the faults were active so remote diagnostics could capture them. No inspection yet by the manufacturer, police, or insurance. Public owner reports describe similar Autopilot-computer thermal failures on HW3 vehicle

Tesla released a new version of FSD: 2026.20.6.11 V14 Lite for my 2022 Model Y Long Range. I installed it overnight and the next morning, several systems become intermittent. The backup camera stopped working immediately, and FSD would drop out, with the message "Take control immediately". I would then lose traffic visualization and other advanced features. Eventually the system would recover and start the cycle all over again. Several times per drive. I took the car to the dealer and they diagnosed it as a failed HW3 computer. The cost to repair it was $2,939 out of pocket since my car was 2 months out of warranty. The car was 100% functional before the V14 Lite update. The dealership denied the problem was related to the update, but the internet now has numerous instances of this problem, and attribute it to the computer running much hotter under this new update, causing components to fail. Our update was installed while the car was in our garage at a temperature in the 70’sF and immediately caused the computer failure before the car even left the garage. I requested and was given the failed computer in case any independent investigation is needed

FORWARD COLLISION AVOIDANCE: WARNINGS

While operating my 2022 tesla model y, the vehicle suffered a catastrophic hardware failure of the onboard vehicle control computer. This total computer failure resulted in an immediate, sudden loss of electronic power steering assist while the vehicle was in motion. The steering wheel became incredibly stiff and heavy, creating a severe and hazarders driving situation. the vehicle was towed to a tesla service center, where technicians confirmed the onboard computer hardware requires a complete replacement. A vital computer failing prematurely on a 2022 vehicle presents an extreme safety risk of crash or injury due to sudden loss of vehicle control.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

As a 100% T&P Disabled Veteran relying on advanced driver-assistance for mobility, I purchased a 2022 Tesla Model Y Performance with Hardware 3 (HW3), which was actively advertised and sold as possessing all necessary hardware for safe, autonomous operation. In practice, the vehicle suffers from safety-critical driver-assist defects—including unexpected disengagements and erratic system choices—due to fundamental HW3 processing and memory bandwidth limitations. Operating a vehicle marketed as autonomy-ready, but constrained by hardware incapable of handling complex traffic scenarios safely, forces constant manual intervention and creates an unacceptable collision hazard for a disabled driver.

FSD / vision system , no warnings , the vehicle is turning left and right on a straight road sunny conditions. I have a video that it wouldn’t let me attach to the case. I had Tesla service review this and they told me it’s standard behavior, this never occurred before and is dangerous and unusable. Autopilot has an issue that Tesla themself can’t detect and when I get into an accident it’ll Be too late. I’ve been complaining about this for 3 months and Tesla keeps telling me it’s standard behavior, this never happened before the car used to drive straight, brand new tires front and back , blanket and aligned the car drives straight while not in autopilot, issue is directly related to FSD and Tesla autopilot.

This week, I was driving my Tesla at approximately 65 mph in the middle lane of a six-lane freeway. Autopilot was engaged. Traffic was moving normally, and I was not aware of any obstacle or hazard that would have required emergency braking. Without any warning, the vehicle suddenly applied the brakes and rapidly decelerated until it came to a complete stop in the middle travel lane of the freeway. I was not pressing the brake pedal. The event occurred unexpectedly and created a potentially life threatening safety hazard. my vehicle came to a stop in a high-speed traffic center lane! After I disengaged Autopilot and pressed the accelerator, the vehicle responded normally. Immediately following the incident, the display showed the message “Autopilot unavailable.” That message later disappeared, and no additional warning messages remained on the screen. I contacted Tesla to report the incident. Tesla reviewed the vehicle’s logs remotely and later discussed the results with me by telephone. During that conversation, I was told that the event was considered an “anomaly.” I was also told that the vehicle logs reflected the event approximately one hour from when it actually occurred and that the logs indicated the vehicle was not operating in Autopilot at the time of the incident. This information was inconsistent with the event, because Autopilot was engaged when the sudden braking occurred. I could not even move to berm. Tesla did not request that I bring the vehicle in for a physical inspection. Instead, I was told there was no reason to have the vehicle examined. During the same conversation, I was encouraged to consider subscribing to Tesla’s Full Self-Driving (Supervised) system, which requires an additional monthly subscription, rather than continuing to use autopilot as a result of a question I asked about two plans. Tesla closed my service ticket without performing an inspection indicating there was no benefit spending $$ to essentially receive no additional

While in Full Self Driving mode in my Tesla, it was making a right turn into a parking lot when it suddenly violently accelerated. Before I could gain control it crossed the parking lot entrance, climbed the curb, and came to rest on a lawn in front of a business. Luckily no one was hurt. It appears the car will be totaled by the insurance company at the completion of their investigation.

On Feb 25, 2026 My 2022 Tesla model Y with only 25k miles on it suddenly stopped knowing where it was and almost drove me into a ditch. All cameras stopped working and the gps was stuck in the same wrong location. (Service Mode showed Primary DAS ECU shows "AP IN COREBOOT" and "Status: INIT." Secondary B shows nominal. Features unavailable. GNSS shows 0 satellites in open sky.) Tesla service said I was outside of warranty and “There is an internal processor issue with your autopilot system that will prevent updates from installing. The only solution is replacing the computer on April 9, 2026, 12:22,” I had had other computer related issues I brought up during regular service visits but weren’t recorded and I was told software updates would fix such as: delayed rearview camera upon startup, navigation volume resetting, headlights staying on for extended periods after exit, and lockout issues. I asked Tesla to document the specific failure codes which they never sent. They said “Tesla diagnostics are showing the primary Autopilot computer is not booting properly, which is preventing cameras, software updates, and related systems from functioning. Because the computer is not initializing, a firmware reinstall will not complete successfully. At this point, replacement of the computer is the required repair to restore normal functionality.” My car had a safety recall during its service appointment that they could not install software for unless I paid $3200 to replace computer. I had total loss of rearview camera (FMVSS 111 violation) and loss of Active Safety Systems (AEB/FCW), but Tesla refused to repair a federally mandated safety defect if I didn’t pay the full repair cost.

I am reporting a serious safety concern involving my Tesla Model Y. While driving, the vehicle’s main center screen (MCU) suddenly failed and entered a continuous reboot loop. This resulted in the loss of critical driving information and controls, including navigation, camera display, and vehicle system status. The issue occurred without any warning and nearly caused a serious accident, as I was unable to safely monitor essential driving information. This failure made the vehicle extremely unsafe to operate. The problem appears to be related to a known MCU system failure affecting some Tesla vehicles. I am concerned that this issue may present a broader safety risk for other drivers. Please investigate this matter for potential safety defects.

The vehicle was delivered with a critical safety defect in the braking system and inoperable safety software (GPS/FSD/Navigation). Upon further inspection by the dealer's own technician, it was confirmed that the vehicle had 'EXTREMELY POOR BRAKE FEEL' and 'EXTREME RUST BUILD UP' on all pads and rotors, which violated Tesla’s 6mm minimum safety standard for used vehicles. Additionally, a physically damaged windshield harness caused the failure of GPS and FSD features. These defects posed a significant safety risk to myself and my family during operation. The dealer has documented and confirmed these safety issues but is now refusing a buyback and is retaliating with storage fees for my rejection of the unsafe product. No warning lights appeared prior to the technician's discovery of the brake defects.

Around 02/10/2026, all of ADAS functions of my 2022 Tesla Model Y has suddenly stopped working, and the rearview was just black. On 02/27/2026, Tesla service diagnosed the car and tole me that the car computer should be replaced and its total repair cost would be about $3,200. My car's mileage was 51,000 at the onset of the problem, so just passed the standard 50K warranty. My car has total loss of rearview camera (FMVSS 111 violation) and loss of Active Safety Systems (AEB/FCW), but Tesla refused to repair a federally mandated safety defect if I don't pay the full repair cost.
