2024 Tesla Model Y driver assistance problems

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.

While preparing to make a left turn on a yellow turn signal with FSD (Supervised) engaged, an oncoming vehicle in the opposite lane approached at high speed. FSD apparently failed to detect it in time; the car hesitated and paused directly in the path of the oncoming vehicle. I had to press the accelerator to avoid a serious collision. FSD's judgment at complex intersections with fast oncoming traffic appears inadequate. Street name unknown.

I was slowing for a red light - I was nearly stopped a safe distance behind the car in front of me, then my Tesla applied automatic emergency braking. There was absolutely no danger or imminent accident. I was not injured, but my dog was thrown forward and hit the dashboard. This happened again when I went to accelerate as the light turned green - I got up to about 5 mph and automatic emergency braking was applied again, this time nearly causing the car behind me to rear-end me (and it generated a few honks as the Tesla wouldn't let me drive through the green light). This is the latest incident - AEB has been triggered two other times in the past year, both times worse than this, but I didn't have video and didn't know where to report it. This has been reported to Tesla, no response (yet). The vehicle/component has not be inpsected by anyone. No warning lamps were on prior to the failure. (note - i do have video of the incident, but i doesn't let me upload mp4)

When you disengage full self driving supervised, a nag screen asking you why you turned off Full Self Driving, blocks controls on your screen, and cannot be turned off without the driver being forced to respond. This is dangerous while parking and in other scenarios. Especially since the only way to get rid of it is by being a distracted driver, as you cannot use all controls without first answering the question as to why you decided to take over for the automated driving. This happens multiple times per drive, per day. I have included a picture of the bag screen from another driver as I did not feel comfortable taking a picture while driving.

1. i was using tesla self driving standard on my vehicle it accelerated up to 19 miles over the recorded speed limit. 2. The speed limit was 55 and it went to 74 way to high and no way to lower it manually 3. Confirmation by the MD State Police radar 4. No inspection 5. There was no warnings. Consumers should be able to set the maximum speed desired or lower it if it goes to high manually, but you can't if you are using self driving options. You can go to chill which is the next level down but that is to slow. Consumers should be able to manual put the speed where they want to drive and feel safe. I was between two cars in the right lane driving down the highway. I believe my vehicle was keeping up with the flow of traffic but no way to slow it down unless i went out of standard self drive. Chill is the one below standard and that is to slow.

I subscribe to tesla FSD and there's a pop up window every time I disengaged from FSD. There's no way to systematically stop it from popping up. It is a serious distraction from driving, as it blocks part of the map and causes me thinking there's something wrong with the car. I want a way to stop it from popping up.

The Full Self-Driving (FSD) system on my 2024 Tesla Model Y repeatedly causes the vehicle to weave or oscillate from side to side within its lane, particularly at highway speeds. The vehicle is available for inspection upon request. The most serious incidents have occurred at highway speeds while traveling in the left lane next to a concrete median. The vehicle has weaved so severely that it has nearly caused me to hit the concrete median. I attempted to steady the steering wheel with my hands, but this was not sufficient to stop the oscillation. I had to immediately disengage FSD to stop the behavior and regain stable control. This has happened more than once. The problem is independent of rain, wet pavement, poor weather, or unusual road conditions. I have experienced it in dry, clear weather and normal road conditions. There are no warning lamps or messages before the weaving begins. Tesla inspected the vehicle for this problem on July 22, 2026. Tesla Service found no physical defect and told me the behavior was a known software/firmware problem that could not be repaired at the service-center level. Tesla personnel indicated that similar behavior was known to be occurring in Europe. I was told that a future software update would correct the problem. Since then, Tesla has released multiple software/FSD updates and my vehicle has received subsequent updates. The weaving may have improved slightly on city streets and at lower speeds, but I have not observed meaningful improvement at highway speeds, where the greatest safety risk occurs. The weaving also creates a risk to surrounding traffic because the vehicle may appear to other motorists to be driven by an impaired or otherwise unsafe driver, potentially causing them to react to its unpredictable movement. Tesla has inspected and acknowledged the problem, but the high-speed safety issue remains unresolved and they do not expect any additional remedy from the dealer for my vehicle.

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.

SEVERE DEFECT: Unprompted autonomous steering overrides manual driving. When Autopilot is OFF, Emergency Lane Departure Avoidance (ELDA) violently yanks the steering wheel, steering TOWARD hazards like oncoming traffic on the left or a mountain/rock wall past the curb on the right. This creates a severe collision risk, overriding safe manual input.DOCUMENTED PROOF: Provided Tesla Service (Palo Alto) over 12 timestamps and several dashcam footage. Technicians physically verified NO internal/external camera obstructions across TWO separate visits. Moving a transponder failed to resolve it.TESLA REFUSAL: Service Center has canceled TWO other service requests without fixing the defect, claiming it the 'system is working as intended.' Crucially, the Manager Jay explicitly admitted this dangerous steering override is a 'known issue for vehicles without FSD' operating on an older, separate software stack prone to these errors. To resolve this critical safety hazard, he explicitly suggested I purchase Tesla's premium Full Self-Driving (FSD) upgrade, claiming the FSD stack fixes it. Tesla is fully aware their base active safety software stack is defective and steers into hazards, yet demands a paid consumer upgrade to resolve it rather than issuing a safety patch or recall.

On XXX at approximately 7:23 a.m., a 2024 Tesla Model Y was traveling westbound on [XXX] in [XXX] in the middle lane at approximately 71 mph with Full Self-Driving (FSD) engaged. While traveling in traffic, the vehicle suddenly initiated a lane change toward the right lane without providing a warning or sufficient opportunity for the driver to respond. While the Tesla was executing the lane change, a vehicle traveling behind it collided with the left side of the Tesla. Following the impact, the driver manually took control and brought the Tesla to a complete stop on the right side of the highway. The system suspected of malfunctioning is Tesla’s FSD driver-assistance system, particularly its automated lane-selection and lane-change functions. The exact cause has not been determined. The vehicle and its electronic data were preserved. Currently, non-inspection was done. The unexpected maneuver placed the Tesla and surrounding motorists at risk because it occurred without warning at highway speed in active traffic and resulted in a collision. The driver had to intervene manually after the impact to control and stop the vehicle safely. At the time of this report, the suspected malfunction has not been reproduced or independently confirmed by a Tesla service center or independent repair facility. No technical determination of the cause has been received. A police officer arrived immediatly after the accident. An inspection was performed by Insurance company over a video. Before the unexpected lane change, there were no warning lamps, messages, audible alerts, or other symptoms indicating that he vehicle was about to initiate the maneuver or malfunction. The lane change occurred suddenly while FSD was engaged. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
