2023 Tesla Model Y Driver assistance Problems

The vehicle experienced a hardware failure of its primary Autopilot computer module (Hardware 3) while parked overnight. Upon starting the vehicle, all advanced driver assistance systems (ADAS) were disabled, including Autosteer, Traffic-Aware Cruise Control, Automatic Emergency Braking (AEB), lane-keep assist, and blind-spot monitoring. The vehicle also completely lost its backup camera functionality, side-repeater camera feeds, and internal safety chimes. Vehicle Service Mode diagnostics showed that the primary processor (ECU Primary A) was stuck in a low-level boot loop, displaying a state of AP IN COREBOOT and a status of INIT. The vehicle gateway active fault code was PM_a041_dasMIA, indicating that the DAS CAN node is missing because the processor was non-responsive on the internal communication network. The failure also disabled the internal cellular modem network, preventing navigation from working unless connected to Wi-Fi. Tesla Service technicians diagnosed the failure as an internal short circuit within a sealed component. Because this module has no moving parts and failed while parked, it represents a premature electrical breakdown of a non-serviceable core component. The sudden loss of Automatic Emergency Braking, forward collision warnings, and the rearview camera creates a safety hazard during operation.

I recall Tesla Full Self-Driving (Supervised) being engaged throughout the trip. While negotiating the curved highway interchange, I experienced an unexpected, sharp steering movement toward the concrete roadway barrier that I did not intend. The vehicle collided with the barrier, multiple airbags deployed, and the vehicle sustained extensive damage, including apparent steering/suspension damage. The vehicle was rendered undrivable. I obtained the dashcam footage and Tesla's vehicle data export. The available records show self-driving features marked "Available" and "Unavailable" in the seconds preceding collision detection, with cruise control recorded as "Standby." A lane-departure/take-control warning was also recorded shortly before impact. These records raise questions about whether FSD unexpectedly disengaged, whether automated steering contributed to the vehicle's movement, and whether adequate warning was provided.

I am reporting a serious safety-related malfunction involving my 2023 Tesla Model Y, which has approximately 55,000 miles. The incident involved multiple vehicle systems, including the front drive motor, propulsion system, traction control, stability control, steering assistance, and braking-related functions. Prior to the incident, I noticed a water-sloshing sound coming from underneath the vehicle, possibly near the rocker panels, following heavy rainfall. After driving for approximately five minutes and parking, I received multiple warning messages indicating that traction control, stability control, and automatic emergency braking were unavailable. Approximately two hours later, I returned to the vehicle, and the warnings had temporarily disappeared. However, about halfway through my next drive, multiple warnings suddenly reappeared, and the vehicle’s driving and braking behavior changed significantly. The regenerative braking stopped functioning, causing the vehicle to continue rolling when I released the accelerator instead of slowing down as expected. When I applied the brake pedal, I experienced unusual vibrations, increased braking effort, and abnormal noises during braking. This was extremely concerning because it affected my ability to slow down and stop the vehicle normally, creating a potential risk of a collision. I documented the following warning messages with photographs: * DI_a138: Front motor disabled * DI_a223: Traction control disabled * DI_a222: Stability control disabled * GTW_w074: Steering assist reduced * DIR_a062: Propulsive power reduced * APP_w009: Automatic Emergency Braking unavailable Due to the seriousness of these malfunctions, the vehicle was towed to an authorized Tesla Service Center for inspection. But the issue was not resolved as they were not able to reproduce the problem.

The contact owns a 2023 Tesla Model Y. The contact stated that while pulling into a parking space with the brake pedal depressed, the vehicle unintendedly accelerated and struck an occupied parked vehicle ahead. Upon shifting into Reverse (R), the failure recurred, causing the vehicle to strike the front bumper of a parked and unoccupied USPS truck, which then struck a parked, unoccupied vehicle. The contact engaged the electric parking brake to stop the vehicle. The contact stated that the forward collision avoidance system failed to engage to prevent the collisions. The front driver's side air bag failed to deploy as expected. The vehicle sustained rear-end damage. The vehicle was towed to an auto collision center, where a superficial diagnostic inspection was performed, and the contact was informed that no failure was found. The manufacturer was notified of the failure and referred the contact to a Tesla Service center and to the NHTSA Hotline for assistance. The failure mileage was 30,616.

On October 7, 2026 at about 5:01 PM, on I-75 near Acworth, Georgia, in clear daylight, my 2023 Tesla Model Y was operating with Full Self-Driving (Supervised) engaged at about 76 mph. The vehicle moved from a general traffic lane into an express lane that was closed, and continued toward physical barricades and an impact attenuator at the end of the closed lane. At least three advance signs indicated the express lanes were closed, including an overhead gantry reading EXPRESS LANES CLOSED directly ahead, and the word EXPRESS was painted on the pavement under the vehicle. The vehicle did not slow, issued no warning or takeover request, and made no evasive maneuver. I avoided the barricades with a reflexive steering input. At that moment there was a concrete divider on my left, a tractor-trailer in the lane to my right, and, as I learned only from the footage afterwards, a vehicle following in the lane I moved into. There was no collision and no injury. Tesla's own vehicle data export confirms the sequence. The Self-Driving state was ACTIVE_FSD continuously from 3:53 PM until 5:01:09 PM, when it changed to UNAVAILABLE in the middle of a rising steering torque (0.42 to 0.92 Nm, peaking at 2.01 Nm). That is consistent with a driver override, not a handover request. No automatic emergency braking event, forward collision warning or takeover alert is recorded in the surrounding two minutes. Speed was 76 mph before the intervention and 63 mph six seconds later, with no brake event. I have preserved all six dashcam cameras for the six minutes around the event, the vehicle data export, and a recording of the in-car dashcam viewer showing "70 MPH, Self-Driving" shortly before the event. The vehicle received a software update on October 11, so I cannot confirm the FSD version active on October 7. Tesla's support interface cited FSD v14.3.11 and software 2026.33.5. When I reported this through the Tesla app, it directed me to submit a bug report and report to NHTSA

On 09/24/2026 at approximately 4:41 PM, my 2023 Tesla Model Y drifted toward the center divider. When I attempted to steer right, away from the divider, the steering felt locked and unresponsive, and the vehicle struck the divider at approximately 24 mph. Airbags did not deploy; no injuries. Vehicle data obtained from Tesla shows: cruise control was engaged approximately 7 seconds before impact and disengaged approximately 2 seconds before impact; about 1.5 seconds before my rightward steering correction, the steering wheel swung hard left (~24°) without driver input; I then applied rightward steering effort and the wheel turned right (up to ~91°) while I was braking; the vehicle displayed "Take control immediately — vehicle departing lane" at the moment of the event; after impact it reported "Automatic Emergency Braking is unavailable" and "Autopilot cameras unavailable." Damage was repaired at a cost of $11,467.75. I am reporting this because the steering behavior — the unexplained leftward swing and the unresponsive steering when I attempted to steer away — suggests a possible defect in the steering or lane-keeping system that could affect other vehicles.

Subject: Urgent Safety Defect: Post-Disengagement Touchscreen Prompt Causes Acute Driver Distraction Feature Involved: Full Self-Driving (Supervised) Post-Takeover Feedback Modal Safety Concern: When a driver manually disengages FSD (Supervised), it is almost always because the vehicle entered a complex, unexpected, or hazardous scenario that demanded immediate human intervention. At the exact second the driver assumes physical control of the vehicle—when 100% of driver visual attention and cognitive bandwidth must be on the roadway—the center display flashes a persistent multi-choice survey requesting feedback on why the disengagement occurred. The Hazard: Visual Diversion During Critical Moments: Presenting bright, interactive UI cards requiring glance time and manual touch interaction immediately after a takeover directly contradicts basic human-factors engineering and crash avoidance principles. Cognitive Overload: Instead of stabilizing the vehicle in manual control, the driver's attention is competed for by an on-screen prompt asking for data categorization. UI Contradiction: While the cabin camera actively penalizes drivers for split-second glances away from the road, the vehicle OS simultaneously prompts the driver to look at and touch the center screen during the most dangerous phase of a driving sequence. Requested Remediation: Provide a toggle under Controls > Autopilot to disable post-disengagement prompts entirely (e.g., "Prompt for Takeover Feedback: OFF"), or suppress all on-screen interactive surveys until the vehicle is placed in Park. Driver telemetry collection should never compromise active collision avoidance. --- This issues happens whenever disengaging fsd. Its not a one time thing. They have updated the software in my car multiple times but haven't fixed this. My location doesn't matter, speed doesn't matter. They added it in an update after more that two years of using the car and I cannot get rid of it.

While using cruise control, the Tesla- several times in the last two weeks- engages "curvature assist" on completely straight roads, slams on the brakes and attempts to steer the car, creating very dangerous situations. This is a very well-known issue with Tesla and they do nothing about it.

I am submitting this complaint regarding a safety defect in the human-machine interface (HMI) and Driver Monitoring System (DMS) of Tesla's Full Self-Driving (Supervised) software. ​1. Automation Complacency & Vigilance Degradation: When operating on highways, the system handles dynamic driving tasks in a manner that induces severe automation complacency and driver fatigue. Placing a human operator in an extended passive-monitoring role inevitably leads to degraded situational awareness, delayed reaction capability, and drowsiness. ​2. Defective In-Cabin Driver Monitoring: The system's interior cabin camera fails to meet effective driver-monitoring standards. When a driver experiences involuntary micro-sleep, closed eyes, or drooping head posture, the cabin camera repeatedly fails to issue audible alerts, escalation chimes, or forced disengagements in a timely manner. The system permits continuous hands-free operation while the driver is compromised by automation-induced fatigue. ​3. Mismatch Between Marketing and Safety Architecture: While the manufacturer classifies the software as SAE Level 2 to disclaim operational liability, the operational behavior and weak attentiveness safeguards encourage disengagement without adequate fail-safes. ​Because the system creates conditions that promote loss of driver alertness without a reliable monitoring system to detect and correct it, this design presents an unreasonable risk of high-speed collision. I have ceased using this software and request that NHTSA evaluate whether the cabin camera monitoring thresholds comply with defect standards under 49 U.S.C. Chapter 301.

I run FSD 96% of the time. It’s so good that I get somewhat complacent. That’s not a character flaw. That’s what a reliable system does to people. The failure mode is simple. Car is holding a curve. Foot accidently brushes the brake. Autosteer disengages. Assist steering torque goes to zero. Wheel unloads. At speed the path goes straight, worst cases, into barrier, pole, or oncoming lane. A heavy Tesla in that geometry is ugly. Tesla’s answer is always the same: the driver disengaged, so it’s not on us. The accident is losing lateral control because of another control (braking) that should only change speed. Brake pedal grazes are easy and inevitable. I can recover a braking event. But I may not recover an instant straight-line on a bend if my hands weren’t on the wheel. Simple fix: Disengage traction but don’t have FSD disengage AutoSteer until I force the wheel. That way FSD knows I have control instead of only assuming that. I love FSD but always feel there is a suicide/killer stick just inches away from my feet. To answer your question, there is no component failure and safety risk is obvious. I can reproduce the scenario by simply tapping the brake on a curve and feel the wheel try to jerk out of my hands. Tesla acknowledges that this is the way the system was designed: complete instant manual takeover. The normal FSD disengagement tone rings. But that is too little, too late for a surprised driver.

The windshield fogs up in front of the front facing camera. It can get dirty such that it is not just a matter of waiting for it to defog. During this time the self driving feature is impaired. The camera should be sealed to the window such that it can not fog up on the inside. The date of incident is the day tesla technician cleaned my camera and I learned how fragile this system is.

Tesla cruise control removed the speed limit functionality as part of its cruise control. I cannot set a maximum speed for the car. Nor can I set a minimum speed for the car. Tesla removed these features through a software update with their autopilot V14. I believe the vehicle is unsafe for myself and others as it does not allow me to set the speed using Traffic-Aware Cruise Control (TACC). Tesla is intentionally removing this feature.

2023 Tesla Model Y – HW3 Autopilot computer/camera system failure My 2023 Tesla Model Y has approximately 54,000 miles and is equipped with the Tesla Hardware 3 (HW3) Autopilot computer. After receiving Tesla's FSD v14 Lite software, the vehicle began intermittently losing camera-based driver-assistance functionality. I observed an APP_w141 ECU Thermal Issue alert. The vehicle subsequently experienced APS_w134_appMia and APS_w135_appCritical alerts indicating that the Autopilot Processor Secondary was losing communication with and detecting a malfunction of the Autopilot Processor Primary. When the problem occurs, camera/vision functions and driving visualization become unavailable or degraded, and the vehicle has reported Self-Driving Features Limited, Cruise Control Unavailable, Adaptive Headlight Features Unavailable, and other driver-assistance limitations. In Tesla Service Mode I have documented the primary Autopilot processor repeatedly changing between INIT, CRITICAL and COREBOOT while the secondary processor remains NOMINAL. A DAS reset can temporarily restore communication, but the failure returns. Tesla has proposed replacing the entire HW3 car computer at a cost of approximately $3,120. I am concerned that this may represent a safety-related HW3 computer failure, particularly because I observed an ECU thermal alert and because the failure removes multiple camera-based driver-assistance and safety functions. I have photographs documenting the alerts and processor states and have an open Tesla service case.

I own a 2023 Tesla Model Y (VIN: [XXX]) equipped with Full Self-Driving and Hardware 3 (HW3) computer. Over the last couple of years, while using Autopilot/FSD, my vehicle has repeatedly exhibited phantom braking, including sometimes coming to a complete stop for no reason. My vehicle has also swerved into the lane of oncoming traffic on many occasions. On one occasion, this happened three separate times in one day, and the following day the vehicle swerved off the side of the road while FSD was engaged. I have reported these incidents to Tesla Service repeatedly for years, including photos of related screen malfunctions and "What Happened" incident data, documented in the Tesla app as well as in-person at service center visits. August 2026 was the first time Tesla told my husband and me that this was a known hardware/software (Hardware 3) issue, despite years of prior reports. Tesla has given conflicting information about whether a hardware upgrade is possible: I was told the HW3 computer cannot be upgraded and was encouraged to purchase a new vehicle instead, while a service representative separately mentioned a $3,000 upgrade option that "probably wouldn't fix the issue anyway." I am concerned this vehicle poses an ongoing risk of a head-on collision or road departure to myself and other drivers.

My 2023 Tesla Model Y suffered a critical factory safety defect: under-torqued front suspension lateral link bolts, causing dangerous clunking noises under Autopilot. The official Tesla Invoice verified the defect and noted it was re-torqued to spec. Crucially, a close friend owning an identical 2023 Model Y in [XXX] experienced the exact same suspension noise. Upon inspecting his car, the Littleton facility attempted to exploit his lack of information by issuing a deceptive out-of-pocket diagnosis estimate of $240.00 instead of honoring the active bumper-to-bumper warranty. Tesla only backed down and waived the fee to $0.00 after being confronted with my personal repair invoice as leverage. This proves Tesla is actively executing predatory billing and hiding a systemic batch safety hazard from uninformed consumers. Regulatory investigators can verify this pattern by auditing the Littleton Service Center's internal torque check logs and warranty waiver histories for 2023 Model Y vehicles. Furthermore, after touchless app-pickup on XXX, Tesla staff omitted any key card communication. Two weeks later, after discovering my physical key cards were missing, I initiated a brand-new service request to inquire, and agent Tony admitted they were left at the front desk, exposing that Advisor Luis Rodriguez falsified records on XXX by logging that the vehicle was retrieved on XXX. This constitutes bad-faith warranty denial, record alteration, and predatory consumer deception. I formally reported this severe failure directly to Tesla Global Compliance on XXX, but have received absolutely zero response to date. Full PDF report of my personal logs provided.

On August 26, 2026, the vehicle’s Full Self-Driving system was involved in three separate incidents. Between approximately 1:00 PM and 3:00 PM, while exiting a parking lot onto a main major street with Full Self-Driving engaged, the vehicle struck the curb. At approximately 6:20 PM, while driving approximately 40 mph on a local road, one street before turning onto the highway, the vehicle began drifting out of its lane without warning for no apparent reason — it is unknown whether this was an attempted automated lane change or a system error. There was oncoming traffic in the adjacent lane at the time; I immediately took manual control of the steering wheel and applied the brakes to correct the vehicle’s path and avoid a collision. At approximately 6:45 PM, while exiting a different parking lot onto a main major street with Full Self-Driving engaged, the vehicle struck the curb a second time. No warning lamp, alert, or message preceded any of these events, and no collision with another vehicle occurred in any of the three incidents. The vehicle has since been returned to the dealer where it was purchased. I am uncertain whether the dealer has separately reported these incidents.

COMPONENT/SYSTEM THAT FAILED: The service brakes failed to stop the vehicle. While reverse-parking at low (parking) speed, I applied the brake pedal and the vehicle did not stop as expected, resulting in contact with an object and vehicle damage. The vehicle is available for inspection upon request; it has been preserved and driven only minimally since the event. HOW SAFETY WAS PUT AT RISK: The brakes failed with no warning. Had a person been behind the vehicle, the failure to stop could have caused injury. This is the only vehicle for a family with three children who are regularly transported in it, and I no longer feel safe driving them. REPRODUCED/CONFIRMED BY A DEALER OR SERVICE CENTER: Not yet. INSPECTED BY MANUFACTURER/POLICE/INSURANCE/OTHERS: The insurer opened and then denied the claim and stated that no vehicle telemetry/data was available to preserve. No independent forensic inspection has occurred yet. Police did not attend. WARNING LAMPS/MESSAGES/SYMPTOMS PRIOR TO FAILURE: NONE. There was no warning light, no alert message, and no audible signal before or during the event. The parking sensors did not beep as they normally do. No ABS or brake warning light appeared at any time before or after. ADDITIONAL RELEVANT DETAIL: Approximately one week earlier, the front lower control arms were replaced. It is UNKNOWN whether the ABS wheel-speed sensor or related wiring was affected; the vehicle displayed no related warning at any time. No injuries occurred.

On February 17, 2026, around 4:20 pm, as I was departing my agency's parking garage structure, my 2023 Tesla Y uncontrollably and un-prompted accelerated at a very high speed. I applied the brake and it would not stop. I nearly killed the security guard at the garage who was trying to direct my vehicle to the correct exit lane. The vehicle ran across a sidewalk adjacent to the garage, ran across a street, hit a street parking meter, ran across another sidewalk, ran across and toppled a perimeter fence around a parking lot across from the garage I exited, ran over concrete wheel barriers, and continued running for about 300 feet before it came to a stop on its own. This duration of this terrifying ordeal was 3 to 5 seconds. The air bags did not deploy. I called 911 repeatedly for Police investigation and report but the Police never showed up. I towed the vehicle to a Tesla Collision Center, which inspected and investigated the accident, and the Tesla Center stated that the FSD system was working properly and did not find anything wrong. I informed the Tesla Center that I did not subscribe to the FSD system service and was not using it during the accident, and they stated that they stand by the determination of their engineering division that reviewed the "blackbox", information gathering device of the vehicle. The vehicle was totaled and non-salvageable. Prior to the accident, the Tesla Collision Center, had repaired the vehicle from a previous accident that occurred on September 25, 2025. There were no warnings before the vehicle uncontrollably accelerated at a very high speed. I have copy of the accident videos. Your platform would not allow me to upload the videos.

I want to raise a serious safety concern with a recent Tesla software update related to Full Self-Driving (FSD). When I disengage FSD, a prompt immediately appears on the main screen asking why I intervened, with selectable options. Here is the issue: When I take over from FSD, it is almost always because something requires my full attention in that moment. That is the exact point where I need to be focused entirely on driving, not reading or interacting with a screen. Introducing a pop-up at that precise moment creates a distraction during a potentially critical transition from automated to manual control. From a human factors and safety standpoint, this feels backwards: - The highest-risk moment is the handoff from FSD to driver - The system is adding cognitive load and visual distraction at that exact time - Even if interaction is optional, the visual interruption alone pulls attention This is not just an annoyance—it has real potential to increase risk in already sensitive situations.

I was pushed to complete an update on my 2023 Tesla Y with an over the air update. This happened last week. Following the update i have been getting a slew of errors when driving my car related to the parking break, brake functions, automatic energy braking and steering are affected. The wording on the app / car says, Alerts - Steering & Braking - Parking brake functions degraded / Parking brake may not apply or release / Parking brake may not apply or release. This causes my auto brake to not engage, my hold break to not engage, my parking brake to not engage. This causes my car to roll at stop / red lights. I have to physically slam by brakes to stop. This is extremely unsafe and Tesla is trying to charge me $130 to diagnose the car to see why the update caused the issue. My car went from fully drivable without any FSD, normal driving to a runaway trainwreck. This happens roughly 20-30 minutes randomly into driving. Not immediately and it is completely random.
