2023 Tesla Model Y: false forward collision warnings

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.

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

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.

I have reported safety issues on this vehicle before, but a new one has arisen which is related to the same. It is the computer shorting out. While in the past I have reported lack of backup camera, lane keeping, cruise control, collision avoidance, now intermittently the power steering fails. I get an error. Thankfully, this occurs when starting up and not while driving (yet), but it is nearly impossible to turn the wheel. As of now, exiting the car, letting the car doors lock and then coming back to the car has solved the issue, but I worry about this occurring while driving. Tesla knows about the computer issues and should take responsibility via a recall rather than a pricey repair on my own as this is a well reported issue. I have received no communication or feedback despite the complaints I have lodged with you and with Tesla. Please intervene before someone gets hurt.

I was driving a Tesla Model Y with Full Self-Driving (FSD) engaged in Standard mode on a wet roadway post-rain. Shortly before the incident, my vehicle had completed a lane change on FSD and was traveling with traffic flow. A vehicle ahead braked suddenly after reacting to another vehicle merging unsafely near a lane split. The stopping occurred quickly, reducing available reaction time. The FSD system did not appear to respond with sufficient braking force or early enough given the conditions. A forward collision warning sounded shortly before impact, but there was limited time to avoid the collision. The vehicle ultimately rear-ended the car ahead. I am submitting this report because of the system’s delayed response in wet conditions, failure to ensure enough space on FSD- especially after a lane change and during a sudden/abrupt traffic slowdown may present a safety concern if experienced by other drivers.

I was operating my 2023 Tesla Model Y Long Range AWD with Full Self-Driving (FSD) engaged at low speed in a residential neighborhood. The vehicle took an incorrect turn into a neighboring driveway instead of continuing on the roadway. I attempted to correct the vehicle’s path. At that point, the vehicle unexpectedly accelerated. I experienced a sudden loss of control and was unable to stop the vehicle before it struck my garage door and entered the garage, causing structural damage to the garage wall. Notably, automatic emergency braking did not activate, and no effective front collision warning intervened, despite an imminent collision with a fixed structure. Tesla’s post-incident vehicle report states that accelerator pedal input was detected, which I believe occurred as a panic response while attempting to regain control after the vehicle took the incorrect turn. However, I am concerned that the vehicle’s software behavior, lack of braking intervention, and failure of safety systems contributed to the incident. This incident raises safety concerns regarding unintended acceleration behavior, FSD path selection errors at low speed, and failure of emergency braking or collision avoidance systems when approaching fixed objects such as garage doors or walls.

While operating my Tesla Model Y in a commercial parking lot at a T-intersection controlled by a stop sign, the vehicle unexpectedly and automatically accelerated without driver intent. The incident occurred during a low-speed maneuver. Upon the unexpected acceleration, I immediately attempted to regain control by applying the brake pedal repeatedly and firmly. Despite clear manual brake application, the vehicle did not decelerate as expected and continued to move forward. I also attempted to stop the vehicle by pressing the Park button, but this action did not stop the vehicle. The vehicle continued uncontrollably for approximately 150+ yards, traveling over curbs, striking a fence, and ultimately colliding with the garage structure of a residential home. Throughout this sequence, the vehicle remained unresponsive to braking and stop inputs. Vehicle data later confirmed that brake pedal application was detected prior to impact, yet braking response was insufficient to prevent continued motion. At the time of the event, the vehicle recorded system fault states, and collision avoidance systems did not activate. Despite significant structural impact and property damage, airbags did not deploy. The incident raises serious safety concerns regarding: •Brake-by-wire system execution during fault conditions •Pedal input arbitration between accelerator and brake •Failure of collision avoidance systems to intervene •Failure of restraint systems to deploy during a severe impact •Vehicle behavior when control systems are in a fault state This event occurred without warning and despite appropriate driver response. Based on vehicle data and system behavior, this appears to be a system-level failure rather than driver error.

While operating my Tesla using the Auto Park function (on 12/8/2025 between 8:45 am and 9:00 am) , which is part of the Full Self-Driving (FSD) system, the vehicle initiated an automated parking maneuver. During the maneuver, the vehicle was reversing into a parking space when it failed to detect a stationary wall located behind the vehicle. The vehicle continued reversing without issuing any visual or audible collision warnings and without performing automatic braking. The Auto Park system did not disengage or request driver intervention prior to impact. The vehicle subsequently collided with the wall, resulting in damage to the vehicle. Based on the vehicle behavior, it appears that the object detection and/or obstacle avoidance functions—relying on onboard cameras and proximity sensing—did not properly recognize the stationary obstacle during the automated maneuver. Following the incident, I contacted Tesla to request a review of vehicle telemetry and system logs to determine whether a fault existed within the Auto Park software, perception system, or associated sensors. Tesla advised that a service diagnostic fee would be required solely to access and review the logs, despite the incident occurring during use of an automated driving feature.

I am writing to formally lodge a complaint against Tesla, Inc. regarding multiple critical safety failures that occurred with my Tesla Model Y (VIN: [XXX] ) during a collision on Saturday, [XXX], while I was traveling eastbound on [XXX] from the [XXX] exit to the [XXX] exit in Pennsylvania. At approximately [XXX], I was driving in the left lane when a BMW SUV abruptly cut into my lane ahead of me, accelerated briefly, and then suddenly braked. I immediately applied the brakes multiple times in an effort to stop my car. Even though there was sufficient space to stop safely, the braking system failed to respond, resulting in a collision with the BMW in front of me. Despite my efforts to avoid the impact, the following dangerous and unacceptable failures occurred at the time of the accident: 1.Failure of Regenerative Braking / Deceleration: When I lifted my foot from the accelerator, the vehicle did not decelerate as expected under Tesla’s regenerative braking system. 2.Failure of Braking System: Despite pressing the brake pedal twice—including a heavy application—the braking system failed to prevent collision, contrary to Tesla’s advertised safety performance. 3.Failure of Collision-Avoidance Features: Critical safety systems—including Automatic Emergency Braking, Forward Collision Warning, and Obstacle-Aware Acceleration—did not engage to mitigate or prevent the impact. 4.Failure of Airbag Deployment: Despite the severity of the crash, none of the airbags deployed, exposing me to serious risk of injury and raising grave concerns about the integrity of the Model Y’s occupant protection systems. 5.Post-Collision Failure of Regenerative Braking: Following the accident, when I attempted to drive the vehicle, the regenerative braking system was completely non-functional, creating a continuing safety hazard and rendering the vehicle unsafe to operate.

My wife was driving the car on March 7th 2025. Before she leaves the house, she had her front defroster on and the windshield was clear before she leaves the house. 5 minutes later, the front windshield became so foggy to the point she could not see anything in front of her and the front defroster was still on. And because of that so foggy windshield she moved out of her lane with no lane departure warning or anything and then she hit the railway pole without any emergency brakes going off or any warning signs letting her that she is about to hit something. The whole front of the car was gone and the car was totally lost but no airbags deployed at all and that was also concerning. Also there was no issues or any warning lamps or messages before the loss. The car was taken to a body shop and was inspected by the body shop and I believe a representative from my insurance company went to inspect the car at the body shop. So these are the parts I felt faulty or causing the safety concern: - front defroster - automatic emergency brakes - lane departure warning - forward collision warning
