2024 Tesla Model Y: false forward collision warnings

Filed Oct 30, 2026 · Driver assistance · CA

Following a software update (2026.38.3.2), without any prior warning messages or symptoms, the vehicle's onboard computer failed on 10/26/26, which resulted in the loss of critical driver-assistance and safety systems. The affected systems included the backup and side-view cameras, blind-spot monitoring, emergency braking, collision warning, lane departure warning/assistance, rear cross-traffic alert, GPS, and adaptive headlights. The loss of the cameras and blind-spot monitoring reduced my ability to identify surrounding vehicles and pedestrians, while the loss of automatic emergency braking, collision warnings, and lane-assistance features eliminated important safety functions designed to help prevent accidents. The problem was confirmed by a Tesla Service Center. According to Tesla's diagnostic findings: "In this instance, your vehicle's computer consists of both a primary and a secondary component. Our diagnostic findings indicate that both parts failed, not due to an internal short, but because of a complete loss of communication between the primary and secondary units." Tesla inspected the vehicle and determined that the computer required complete replacement. The vehicle is currently at the Tesla Service Center awaiting repair and will be unavailable for inspection. A previous recall (25V‑002) addressed a similar computer failure and relied on a software update as a remedy, however the recurrence of a related failure raises concerns about whether that remedy was sufficient. I am concerned that the automatic software update on 10/26/26 may have contributed to the failure of the car computer. The fact that the failure occurred after the update, without any prior warning, and resulted in the loss of multiple critical safety systems presents a serious safety concern. A software update should not leave a vehicle without essential safety equipment or render multiple driver-assistance systems inoperable.

My 2024 Tesla Model Y (VIN [XXX]) has lost all forward camera-based safety and driver assistance functions. The vehicle displays alerts that Automatic Emergency Braking is unavailable, Park Assist is unavailable, adaptive headlight features are unavailable, and that self-driving is degrading and the vehicle may stop. Autopilot and Full Self-Driving will not engage. The side repeater cameras and the rearview camera still display images normally on the touchscreen, so the failure is not a loss of video display. The loss of Automatic Emergency Braking and forward collision warning means the vehicle has no automated protection against a frontal collision, and the loss of adaptive headlights and auto high beam means the high beams no longer dim for oncoming traffic. I performed a touchscreen reboot and a full power-off reset, and the condition returned. The vehicle is equipped with HW4 hardware and falls within the model years covered by the federal safety agency campaign 25V002000 (Tesla SB-25-00-001) concerning a computer circuit board short, though my VIN was not included in that recall population. I am reporting this because a vehicle sold with these active safety systems is now operating without them, and I believe other owners of vehicles in this build range may be experiencing the same failure.

On 7/22/2026 between 6pm and 7pm PST, I was driving my Tesla Model Y on I-405 southbound in Orange County, CA, between the Westminster Blvd exit and Exit 73, with Full Self-Driving (Supervised) engaged. The incident occurred at an express lane ingress/egress transition zone where a physical barrier separates the express and general-purpose lanes. While in FSD mode, the vehicle initiated a lane change on its own. During the lane change, the FSD system misjudged the lane boundary and steered the vehicle into the lane divider/barrier. The vehicle struck the divider on the front right side. The failed system is the FSD/automated steering and lane change function. No forward collision warning sounded and no automatic emergency braking activated before impact with the fixed barrier. There were no warning lamps, alerts, or symptoms prior to the failure; the system initiated and executed the lane change without indicating any problem. The impact damaged the front right body panel, front right bumper area, and the right headlight. My safety and the safety of vehicles in adjacent lanes was put at risk, as the collision occurred at roadway speed during an automated maneuver I did not initiate. Had the divider been a vehicle or a pedestrian work zone, the outcome could have been far more severe. All FSD telemetry, camera footage, and vehicle data from the incident should be available from the manufacturer, and I have requested the vehicle data report from Tesla. The vehicle is available for inspection upon request and is being taken to a Tesla-certified collision center for repair. An insurance claim is being filed with my carrier. The vehicle has not yet been inspected by the manufacturer or police.

Incident Description (in my own words): We were driving southbound on [XXX] from New Hampshire back to Boston in our Tesla Model Y. Traffic became increasingly congested and slowed to a crawl. My wife was driving, and I was in the front passenger seat working on my laptop. As traffic built up, my wife became momentarily distracted and did not apply the brakes in time. I noticed, in my peripheral vision, the vehicle ahead of us—a truck—suddenly filling the windshield. At that point, I heard the forward collision warning alert, but it activated extremely late, essentially at the moment of impact. The vehicle did not automatically brake or stop, despite the low speed, close proximity, and clear visibility of the truck ahead. We collided with the truck in front of us. Damage was minimal (license plate damage and a small dimple on the front of the vehicle), but the safety concern is significant. Both of our Teslas are configured with forward collision warning set to “Early.” Under normal circumstances, this alert triggers frequently, sometimes conservatively. In this incident, however, the warning activated far later than expected, and there was no automatic braking intervention prior to impact. The front camera appeared clean and unobstructed. I am filing this complaint because this behavior undermines my confidence in the vehicle’s collision avoidance and automatic emergency braking systems. I am also filing a similar complaint for our Tesla Model 3. I am now anxious about whether the software will perform as expected in situations where driver attention lapses briefly—precisely the scenario these safety systems are designed to mitigate. I am requesting that the federal safety agency review this issue, as the system did not behave in a manner consistent with its intended safety function.

I continue to get completely FALSE forward collision warnings. Part of this is because my front camera housing keeps fogging up and over the past 529 weeks I’ve gotten a half dozen false FCWs. When these faulty alerts occur, a loud audible beeping is heard and red alerts are displayed on the screen. These faulty alerts are dangerous distractions, causing panic, fear, and uncertainty in the driver, causing them to take their attention off of the road while they assess what just occurred. This is a critical flaw in the functionality of Tesla vehicles that the company has refused to address. This also makes me insurance rate spike way higher and I’m getting charged extra for this.
