Tesla Model Y hesitation problems

Filed Oct 26, 2026 · Driver assistance · CA

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 am reporting two nearly identical safety incidents involving Tesla Full Self-Driving (Supervised) on my Model Y. In both cases, the vehicle failed to detect a stationary concrete pillar and did not apply automatic braking, resulting in collisions. First Incident – September 16, 2026 While using FSD (Supervised) to reverse into my residential driveway, the system hesitated due to a parked vehicle on the left side. Instead of completing the reverse maneuver, the vehicle moved forward and struck a door pillar / gate post. I intervened and took over control only after the impact had already occurred. The vehicle sustained visible damage (scuff/dent on the side/rear area). Photos are available. Second Incident – October 4, 2026 Again using FSD (Supervised) in a similar residential parking/driveway situation, I believed the vehicle was reversing and would correct its path. Without any warning or automatic braking, the vehicle continued and struck a concrete pillar. I had essentially no time to react before contact. I stopped the vehicle after the impact. Additional damage occurred. Photos of the vehicle position relative to the pillar and the resulting damage are available.

Yep — this follows the federal safety agency guidelines in your screenshots and avoids your name, VIN, phone number, or other personal information. You can paste this directly: While Full Self-Driving (FSD) was engaged, I was stopped in the left-turn lane at the intersection of [XXX] and the roadway that changes between [XXX] and [XXX]. The traffic signal was red, and I was waiting to make a left turn. When the protected left-turn signal turned green, the vehicle did not begin the turn. I pressed the accelerator to prompt the vehicle to proceed, as I have previously done when FSD hesitates at a green light. Instead of following the left-turn lane and turning left, the vehicle accelerated straight ahead toward another vehicle in front of me. The other driver had to swerve to avoid being hit. I immediately took manual control, steered away from the other vehicle, and completed the left turn myself. A collision was narrowly avoided. There was no impact and no injuries. The FSD behavior put both vehicles at risk because the vehicle attempted to proceed straight from the left-turn lane rather than following the protected left-turn signal.

I was using my cars FSD program and it nearly turned me in front of an oncoming Semi truck. This was after it hesitated to turn the car when it had a safer opportunity. I thought it would wait but then it started to turn and I had to stop it, which left me slightly out of my lane which was scary too, with a giant truck coming head on.

Separately, the system could not hold a consistent speed on open highway with no vehicle ahead. It would surge from a set 70 mph to roughly 72-73 mph and then drop back, repeatedly, producing a pulsing acceleration and deceleration. The system also hesitated frequently and issued repeated audible alerts without an identifiable hazard present. I previously filed a complaint regarding phantom braking on this same vehicle (ODI number 11450326, filed February 4, 2022), which described nearly identical behavior triggered by trucks on the same Georgia-to-New Jersey route. That complaint concerned FSD/Autopilot software from 2022. The behavior described here occurs on Tesla’s current v14 Lite software released to Hardware 3 vehicles in July 2026. The defect has persisted across more than four years and multiple software generations. Unexpected hard braking at highway speed with no hazard present creates a rear-end collision risk to my vehicle and to following traffic.

I am submitting this complaint to request an investigation into a serious safety defect involving my Tesla vehicle. On multiple occasions, the vehicle has experienced a significant and unexpected loss of acceleration when I attempted to enter or cross intersections. Despite pressing the accelerator, the vehicle failed to respond as expected, leaving me unable to accelerate normally while entering active traffic. This is not a minor hesitation or inconvenience. It is a serious roadway safety hazard. Drivers rely on immediate acceleration when crossing intersections, turning across traffic, or merging. A vehicle that unexpectedly limits acceleration can place occupants directly in the path of oncoming vehicles, creating a substantial risk of a severe collision, serious injury, or death. I reported this issue to Tesla Service and provided multiple timestamps documenting the events. Tesla was unable to identify any fault codes or provide a diagnosis and indicated that because no fault was recorded, the issue could not be confirmed. Through independent research, I found numerous reports from other Tesla owners describing substantially similar acceleration limitation events. Many reports specifically reference Obstacle Aware Acceleration as a possible cause, and some owners report that disabling the feature resolved the issue. If a safety system can falsely detect an obstacle and reduce acceleration while a driver is actively entering an intersection, the system itself may create a greater danger than the one it is designed to prevent. I respectfully request that the federal safety agency investigate whether Tesla vehicles are experiencing unexpected acceleration limitation or torque reduction during intersection entry and traffic merging situations, evaluate the role of Obstacle Aware Acceleration and related software systems, determine whether a broader pattern exists, and assess whether corrective action or a recall is warranted. This could cause serious injury or fatal crash

Hello, I am reporting a safety issue with the Full Self-Driving (FSD) system on my 2023 Tesla Model Y. The vehicle has been taken in for service four separate times for this issue. During these visits, Tesla service technicians were able to reproduce and confirm the problem. I have been explicitly advised in writing by Tesla service not to use the Full Self-Driving system due to safety concerns and to use standard AutoSteer instead. While FSD is engaged, the vehicle exhibits dangerous and unpredictable behavior, including: Crossing over double yellow lines into opposing traffic, Driving significantly below the speed limit (e.g., ~4 mph in a 25 mph zone), Stopping in the roadway without any traffic or obstructions, Swerving within the lane while attempting to maintain position, Hesitation during turns, stop signs and at intersections. Tesla has attempted multiple repairs, including replacing steering-related components and multiple cameras across separate service visits. These repairs did not resolve the issue. At my last service visit Tesla has since indicated that the problem is likely software or firmware-related and that there is currently no available fix, with a recommendation to wait for a future update of an unknown timeline. If their statement is correct, this issue should be affecting every vehicle out there on the same software. At this time, I have been advised not to use a system that controls steering, braking, and acceleration due to safety concerns, and no timeline or resolution has been provided. I am submitting this complaint because the system behavior presents a potential safety risk to myself, passengers, and other drivers, and the manufacturer has not provided a current fix despite multiple confirmed service visits. I am attaching my last service invoice only in regards to this matter where they indicated to not use FSD, but I can provide other documentation showing the replacement of cameras and steering parts as well as videos if needed.

Yesterday at about [XXX] I was driving using FSD. I was making a left turn on a green arrow turning from [XXX] onto [XXX] . My car hesitated, then accelerated and then abruptly braked nearly causing me to be rear ended by the SUV behind me who was angrily beeping at me. I had to rapidly accelerate to avoid being hit. The left turn signal was green before during and after my turn. I believe that the sun shining brightly on the traffic light made it difficult for my Tesla to accurately recognize that the turn signal was green. I felt this was very unsafe.

I am reporting a recurring safety defect involving the Full Self-Driving (Supervised) system on my pre-owned 2023 Tesla Model Y Dual Motor Long Range (VIN: [XXX] ), equipped with Tesla Hardware 3. Component/System: Full Self-Driving (Supervised) software and driver-assistance control system. The vehicle remains in my possession and is available for inspection upon request. Description: From the time of purchase (approximate mileage ~66,549), the FSD system repeatedly exhibited unsafe behavior during normal operation on public roads, including straddling two lanes, drifting toward lane markers, stopping at green lights or within intersections, hesitating mid-intersection, and failing to complete routine turns. These behaviors required frequent human intervention and made the system unsafe to use. Safety Risk: The behavior created a risk of collision with other vehicles and posed a danger to occupants and other road users, particularly when stopping unexpectedly at green lights or hesitating in intersections. Confirmation/Inspection: The issue was reported multiple times to Tesla Service and escalated internally. Tesla inspected the vehicle and confirmed in writing that the FSD behaviors were “behavioral” and not resolvable by hardware replacement at that time, with no known fix or timeline. Warnings: No warning lamps or fault messages were displayed prior to or during the incidents. Despite these issues, Tesla continued to advertise the vehicle as FSD-capable and accepted payment for the FSD subscription. I provided Tesla formal written notice via certified mail, delivered November 26, 2025, with no response within the stated timeframe. Although a recent software update has temporarily improved behavior, the defect existed at purchase and persisted through multiple service interactions. Additional documentation, service records, and communications are available upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While Full Self-Driving (Supervised) was fully engaged (blue steering wheel icon active), the vehicle approached an uncontrolled intersection, selected the wrong path, hesitated severely (camera shaking violently), provided ZERO visual or audible warnings, and completely ignored driver's emergency brake input (pedal depressed >90% approximately 1.5 seconds before impact). The vehicle continued forward by inertia and collided with a roadside curb, resulting in wheel damage. Attached dashcam video clearly shows: • FSD active throughout the event • No alerts or chimes • Violent steering oscillation/hesitation • Driver's foot slamming brake pedal with no deceleration • Impact despite timely braking This incident matches the ongoing the federal safety agency investigation PE25-012 regarding FSD intersection hesitation and failure to respond to driver input.
