2023 Tesla Model Y driver assistance problems

Filed Oct 30, 2026 · Driver assistance · CA

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 federal safety agency 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 the federal safety agency

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.
