Automatic Emergency Braking Problems of Tesla Model Y - part 2

Safety features on vehicle stopped working after software update was pushed to my vehicle. Gps, all cameras including backup camera and ones used for blind spots, and cruise control have all stopped working. Time displays incorrectly due to gps issue and night mode stays on so rear view & back window stay dark making it hard to see other vehicles around me during the day. I’ve followed all recommended steps to resolve and issue persists.

Yesterday evening, my wife and I had friends over to our house, and we were excited to show them our new Tesla. We offered to take them on a short drive around town using the full self-driving (supervised) feature. At approximately 8:00 pm, we entered the address of our local sam's club as the destination. As the vehicle approached sam's club, it entered the parking lot through the gas station entrance, which appeared to be the expected route. However, instead of proceeding to a parking space, the vehicle unexpectedly continued driving and attempted to make another loop toward the gas station entrance. At that moment, an SUV was exiting the gas station. The Tesla steered toward the SUV and then continued toward a brick wall where there was no roadway. It appeared the vehicle was attempting to drive into an area that was not a valid path. I immediately disengaged full self-driving, took manual control of the vehicle, and reversed to avoid what could have been a collision with both the SUV and the brick wall. The occupants of the other vehicles were understandably upset because the situation appeared unsafe. This was a very dangerous situation that placed my wife, our friends, and me at risk. Had I not intervened immediately, the incident could have resulted in a collision causing property damage or personal injury. I am reporting this event so your engineering team can investigate the behavior and improve the full self-driving software. I hope this information helps identify and correct this issue to improve the safety of the system for all Tesla owners and the public.

Systemic powertrain safety defect: catastrophic loss of propulsion & failure of dual-motor redundancy. 1. Incident & safety risk: while traveling in the far-left hov lane of a 6-lane interstate highway, the vehicle experienced an uncommanded, unwarranted automatic emergency braking (aeb) intervention during a controlled lane change. This sudden deceleration instantly triggered a complete powertrain collapse and total loss of propulsion. The vehicle came to a dead stop in a live highway lane. The driver (me), passenger, and our [xxx] infant were stranded in lane 3 of a 6 lane highway for ~35 minutes until highway patrol units arrived to manually push the vehicle across live traffic to the shoulder. This near-miss was an immediate, severe life-safety crisis not just for the occupants but also to others on the road. 2. Symptoms & alert codes: there were zero warning symptoms prior to the incident. Immediately upon the power collapse, the touchscreen displayed critical faults. Active diagnostic telemetry confirmed alert codes: di_a137 (no capable drive units) di_a063 (system graceful power off) 3. Manufacturer confirmation & inspection status: the failure was confirmed in writing by the manufacturer’s service center. The diagnostic invoice explicitly states: "the rear drive inverter experienced an unintended reset due to an error. Sudden power reduction and shutdown while driving. " the vehicle is currently held at the manufacturer's facility and is fully available for inspection. 4. Engineering assessment: as a mechanical engineer, my assessment is the surge through the aeb event to the inverter’s DC-link was unable to damp this load, forcing a hardware logic reset. Crucially, the software logic failed to partition this fault. In a dual-motor architecture marketed as having built-in powertrain redundancy, a localized rear inverter reset should be isolated, leaving the front motor operational to safely navigate out of traffic, this did not happen.

On June 23, 2026, at approximately 7:45 am central time, I was operating my Tesla in full manual drive mode on us highway 35 westbound between denton and fort worth, texas. No driver assistance, autopilot, or automated steering system was activated or engaged by me at any point prior to or during this incident. Without warning and without any driver input, the vehicle autonomously activated an automated steering and driving assistance system, assumed full control of the vehicle, and did not return manual control to me despite my attempts to intervene and regain control of the vehicle. The incident occurred during active rainfall and wet road conditions. The vehicle, while operating under its own autonomous system control without driver consent, drifted and struck the guardrail on the driver's left side. Following the initial impact, the vehicle continued moving and did not stop. The automated system remained active and did not disengage following the collision. The vehicle did not return control to me until a wheel separated from the vehicle. This incident was not caused by driver error. The vehicle's automated system activated without driver input or consent, overrode manual driver control, prevented the driver from regaining control of the vehicle, caused a collision with the guardrail, and continued operating after impact until mechanical failure occurred in the form of wheel separation. I am requesting a formal investigation into this uncommanded autonomous system activation as a safety defect. This type of failure poses an extreme and immediate safety risk to drivers, passengers, and the public.

On June 7, 2026, while full self-driving (fsd) was engaged, my 2025 Tesla Model Y drove itself forward out of a parking spot and struck a stationary landscape rock directly in its path. The vehicle did not slow, brake, or steer to avoid the obstacle before impact. The rock was a fixed object roughly 20 inches tall, clearly visible in the vehicle's forward (windshield) camera from a complete standstill, before fsd began moving the car. It stayed visible as the car advanced and dropped into the camera's near-field blind zone just before contact. The vehicle struck it with no apparent detection or avoidance. This is a serious safety concern beyond the resulting property damage. An obstacle of this height is in the same range as a small child or a crouching person. An automated driving system that fails to detect and respond to a fixed, clearly visible object in its direct path presents a significant risk of injury. The dashcam footage (windshield camera) is available and shows the obstacle visible from a standstill. The vehicle's front bumper camera feed is not saved to dashcam, so only the manufacturer's internal logs can confirm whether the obstacle was detected and how it was classified. I reported this to the manufacturer's service team and requested a log review; they declined to confirm detection and directed me elsewhere. No warning lamps or alerts appeared before the impact. Footage and repair documentation available on request.

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 NHTSA 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.

On xxx, at approximately 8:01:49 am eastern time, my 2024 Tesla Model Y (VIN: [xxx]) was operating under full self-driving (fsd) software version 14. 3. 3 when the system directed the vehicle into the outer wall of my residential garage without driver input. Fsd was actively engaged at the time of the incident. The vehicle sustained significant damage to the front bumper fascia and wheel well trim. Additional damage includes a cracked front fog light/corner lens assembly with surrounding fascia stress, also caused by the same incident. The incident also caused paint transfer damage to the garage wall trim. I have preserved dashcam footage documenting the incident, which is consistent with fsd-directed vehicle behavior. I am referencing NHTSA preliminary evaluation pe25012 as this incident is consistent with the pattern of uninstructed fsd-directed maneuvers currently under federal investigation.

Tesla Model Y is experiencing a front passenger airbag sensor failure (OCS) covered by factory bulletin sb-23-20-002 alongside tmps and eaeb alerts. Tesla corporate resolutions is refusing to fix these safety system failures with out charging $1400 out-of-pocket, citing warranty expired.

Incident report – 2026 Tesla Model Y date of incident:xxx time of incident: 12:30 am location: [xxx] I was operating my 2026 Tesla Model Y and was driving manually. Full self-driving (fsd), autosteer, and other self-driving functions were not engaged at the time of the incident. While traveling on highway 16 at approximately 60 mph, the vehicle approached the right-side white lane line. At that point, I experienced a sudden steering intervention that turned the vehicle sharply to the left. The steering input was unexpected and occurred while I was manually controlling the vehicle. Following the steering intervention, the vehicle crossed the centerline into the opposing lane of travel and continued off the roadway into the ditch on the opposite side of the road. The incident resulted in damage to the vehicle. Road conditions were dry. Weather conditions were safe. Lane markings were clear. I am requesting that Tesla preserve and review all vehicle telemetry, event logs, steering-assistance records, and any other relevant data associated with this incident. Specifically, I request an investigation into whether lane departure avoidance, emergency lane departure avoidance, or any other driver-assistance feature activated and contributed to the steering maneuver. I am also requesting a determination regarding responsibility for the resulting vehicle damage and whether Tesla will reimburse repair costs if a system malfunction or defect is identified. Supporting documentation, including photographs, dashcam footage (if available), repair estimates, and other evidence, can be provided upon request.

Phantom brake incident today,5/26/26. Traveling 35mph, brakes slammed on for no apparent reason. Seatbelt tightened and my head launched forward. Neck is very strained.

I have written several times before about my car's phantom braking in cruise control. When the santa fe Tesla dealer, where I bought the car, told me recently that the problem had been fixed, I was disappointed they didn't bother to tell me, but thrilled to hear the news. On may 12-13 I drove over 900 miles. I tried cruise control for significant portions of both drives and did not experience one problem. Finally, I thought, they fixed the problem. . . And how nice it was to have cruise control for extended drives. Not so soon: on may 19th I was driving 2 friends up to volunteer at the wildlife refuge on I-25 in northern new mexico. The phantom braking happened again. My friends were dismayed. . . One thought I had seen something in the road that she didn't see. The other, in the back seat, tried to understand what happened. Please, this is beyond the pale! of course I will call and take the car in to the dealer. . . An hour's drive for me. I will be surprised if they fix it, and if they do it under warranty. I did just buy new tires (see previous report about original tires with multiple flats and not even making it to their 40,000 mile warranty) so I'm no longer worried about getting a flat in the rural areas where I live and drive.

While my vehicle was operating in full self-driving (fsd) mode, it encountered an accident upon attempting to park in my garage. The collision resulted in substantial damage to the driver’s side rear end and the garage wall. Notably, there was no manual intervention during the entire journey from my son’s school and the parking attempt. The fsd system failed to detect the proximity of the garage and did not initiate braking or provide any warning before impacting the wall. In this instance, the fsd system exhibited multiple failures. I have subsequently reported the incident to Tesla.

I am writing to formally raise a serious concern regarding the functionality of Tesla’s full self-driving (fsd) system. On may 11th, while the vehicle was operating under fsd, I experienced an unexpected disengagement of the system, which then reengaged on its own without any input from me. This erratic behavior caused the vehicle to hit the garage door and resulted in a crash.

The full self driving system has malfunctioned and is failing. I was put in incredibly dangerous situations that were near potentially fatal accidents. Had someone been a little bit closer when following me, I would not have had enough time to counter the issue. Yes it has been confirmed but not nearly to the extent that I have experienced it it has been inspected by a local service center from the company. There have been some visibility warnings but nothing else.

In the 5 years we have had this vehicle there have been multiple issues with the self driving feature including: 1)phantom braking on busy freeways in twin cities 2)swerving randomly into the other late on a curve on 4 lane hwy at 65 mph (hwy 10 near little falls, mn) 3)attempting to switch lanes into fast traffic when we were at a standstill in rush hour traffic (interstate 35e southbound) 4)slamming brakes on on a 2 lane road on a curve because there was a semi in the other lane (that had not crossed the line) mn hwy 64 5)being a short way from exiting the freeway and having the car jump back into traffic (interstate 35e northbound at hwy 96) 6) slammed on brakes when the car in front of us was exiting hwy 10 normally on an offramp going northbourd around the city of rice, mn. These are some of the most egregious errors the car has made, but there are more not listed. I try it on occasion when there is a software update. It is not safe though- almost without fail I need to take over each time I try it. As elon musk said on 4/22/2026 "hardware 3 simply does not have the capability to achieve unsupervised fsd due to physical computing and memory limitations. " the full self driving is dangerous, yet each time I get in the car the computer encourages its use.

Component: suspension: front — lower lateral and compliance link assemblies; missing and backed-out lateral-link-to-subframe fasteners; torn bushings beginning in xxx, the vehicle produced a reproducible knocking noise from the front end when reversing and turning at parking-lot speeds, with no dashboard warnings. Tesla service ([xxx], invoice xxx) verified the noise and documented on the invoice that the cause was: 1. A front left lateral-link-to-subframe mounting bolt missing entirely; 2. A second lateral-link fastener significantly backed out; 3. Torn bushings in both front lower compliance links. The technician replaced both front lower lateral link assemblies and both front lower compliance link assemblies with new hardware (invoice line items: xxx lateral links; xxx and xxx compliance links). Total customer cost for the suspension work: $1,539, out of warranty; goodwill and defect coverage were denied in writing as "wear and tear. " a structural fastener missing entirely from a primary front suspension link is not ordinary wear. It is the precursor condition to the lateral-link separation investigated under pe26006, which covers this vehicle by year and model. With one bolt absent and the second backed out at under 30,000 miles, this vehicle was effectively one fastener away from the detachment event the investigation documents. The contemporaneous torn bushings in both compliance links reinforce premature component failure, not age-related degradation. No crash, fire, or injury occurred, and the vehicle remained drivable. However, the failure occurred without warning on a safety-critical steering and suspension load path.

C. 552(b)(6).

On xxx at approximately 8:30 pm, the vehicle was operating under full self-driving (supervised) mode when it failed to detect or react to a stationary pole, resulting in a front-end collision. 1 system failed: the full self-driving software, Tesla vision camera system, and automatic emergency braking (aeb) failed to detect the obstacle or apply brakes. The vehicle is available for inspection upon request. 2 safety risk: the autonomous driving software drove the vehicle directly into a fixed object without warning, creating a severe collision risk for occupants and nearby pedestrians. 3 confirmed by dealer: yes. The vehicle was taken to the Tesla service center in [xxx] on xxx, where technicians officially captured and logged the diagnostic vehicle data for this specific incident under my active service file. 4 inspected: the physical hardware and system logs have been initially inspected and captured by Tesla service technicians. 5 prior warnings: there were zero warning lamps, chime alerts, or visual indicators on the center console display prior to the impact. The system treated the obstacle as navigable space information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

### summary: sudden unintended acceleration (sua) from a stationary position. ### vehicle configuration: 2023 Tesla Model Y long range awd. Battery type: nmc. ### incident details: on April 19, 2026, at approximately 10:00 a. M. , the vehicle was stationary on a flat surface at 6722 vista del Mar Ave, san diego. I was in the driver's seat with the vehicle "on" but stopped, conversing with two witnesses. My feet were completely clear of both the accelerator and brake pedals. ### the event: without driver input, the vehicle suddenly and forcefully accelerated forward. I immediately slammed the service brake with full force. The vehicle traveled approximately 20 feet before the brakes brought the car to a halt. ### evidence & gaps: two eyewitnesses confirmed the vehicle moved autonomously without pedal interaction. A manufacturer data report was requested, but it showed a specific data gap for the exact seconds of the acceleration event, despite providing second-by-second logs for the rest of the day.

While in self driving the car veered into a driveway and hit a house.

On April 11 2026, I was involved in a serious accident involving my 2026 Tesla Model Y. At the time of the incident, I was returning home from my daughter’s event in downtown and had just entered my residential driveway. As I approached the driveway, I applied the brakes and slowed the vehicle. While momentarily stationary or near-stationary, I spoke to my wife, who was seated in the front passenger seat, advising her to secure the food she was holding due to the uneven surface of the driveway. Upon removing my foot from the brake pedal, the vehicle suddenly and unexpectedly accelerated without any input . The vehicle proceeded forward and collided with my garage door. Notably, no collision warning alerts were issued, and no automatic emergency braking system engaged prior to or during the impact. Following the initial collision with garage door, the vehicle failed to stop and instead continued to accelerate into the garage, striking a refrigerator. The impact resulted in substantial damage to the refrigerator and caused extensive structural harm to the property, affecting the garage, adjacent living space, floors, and interior walls. The severity of the collision triggered deployment of the front airbags. At the time, my wife was seated in the front passenger seat, and my [xxx] daughter, along with her friend, was seated in the rear of the vehicle. Emergency services were called, I have forehead bruises and a burn on my hand from airbag deployment. My wife is advised physiotherapy for severe back pain and my daughter has since experienced ongoing emotional distress, nightmares. I am dealing with car and home claims issues for damages I am seeking a formal investigation into the cause of this incident, specifically addressing: 1)the unexpected and unintended acceleration of the vehicle 2)the failure of the vehicle to stop after the initial collision with the garage door 3)the absence of forward collision warnings and failure of automatic emergency braking . Information redacted pursuant to the freedom of info.

On [xxx] 1512pm. Drive on [xxx] with auto pilot driving. Seen on construction and hit some object driver side by front bumper , fender, side mirror,door and wheel. Couldn't avoid crash by control handle. There is none of airbag action. All deployed. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Car was in fsd mode, backing out of a parking place very slowly when it accelerated and crashed into a post and wall. No other cars or people were involved, but no alarms, beeps, or warnings were sounded and the screen/monitor/camera systems went blank simultaneously. This caused over $5000 worth of damage per the estimate provided by the only body shop in the area allowed to fix Teslas. There is also a gap in saved data per our retrieval from the usb and camera installed in the vehicle.

The vehicle was delivered with a critical safety defect in the braking system and inoperable safety software (gps/fsd/navigation). Upon further inspection by the dealer's own technician, it was confirmed that the vehicle had 'extremely poor brake feel' and 'extreme rust build up' on all pads and rotors, which violated Tesla’s 6mm minimum safety standard for used vehicles. Additionally, a physically damaged windshield harness caused the failure of gps and fsd features. These defects posed a significant safety risk to myself and my family during operation. The dealer has documented and confirmed these safety issues but is now refusing a buyback and is retaliating with storage fees for my rejection of the unsafe product. No warning lights appeared prior to the technician's discovery of the brake defects.

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. [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle: 2023 Tesla Model Y VIN: [xxx] mileage: approximately 40,531 miles software version: 2025. 45. 9 fsd (supervised) version: v14. 2. 2. 4 while driving on [xxx] near the [xxx] entrance in mission viejo, California, the vehicle was operating under full self-driving (supervised) mode. As the freeway lane ended/merged, the vehicle unexpectedly performed a sudden full stop at freeway speed. There was no visible obstruction in front of the vehicle. Multiple vehicles behind me had to brake abruptly to avoid a rear-end collision. The system did not provide any audible or visual warning before the sudden braking. This has created a serious safety risk due to the high-speed freeway environment. This issue appears to be related to lane-ending or merge interpretation by the fsd system. I am concerned that this behavior could result in a rear-end collision. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle will suddenly apply brakes while using standard cruise control for no apparent reason. This is extremely dangerous as it has almost caused several accidents on the highway. I have almost been rear-ended several times. This is a very common problem and well documented problem referred to as "phantom braking" on Teslas and something needs to be done immediately.

On February 17, 2026, around 4:20 pm, as I was departing my agency's parking garage structure, my 2023 Tesla y uncontrollably and un-prompted accelerated at a very high speed. I applied the brake and it would not stop. I nearly killed the security guard at the garage who was trying to direct my vehicle to the correct exit lane. The vehicle ran across a sidewalk adjacent to the garage, ran across a street, hit a street parking meter, ran across another sidewalk, ran across and toppled a perimeter fence around a parking lot across from the garage I exited, ran over concrete wheel barriers, and continued running for about 300 feet before it came to a stop on its own. This duration of this terrifying ordeal was 3 to 5 seconds. The air bags did not deploy. I called 911 repeatedly for police investigation and report but the police never showed up. I towed the vehicle to a Tesla collision center, which inspected and investigated the accident, and the Tesla center stated that the fsd system was working properly and did not find anything wrong. I informed the Tesla center that I did not subscribe to the fsd system service and was not using it during the accident, and they stated that they stand by the determination of their engineering division that reviewed the "blackbox", information gathering device of the vehicle. The vehicle was totaled and non-salvageable. Prior to the accident, the Tesla collision center, had repaired the vehicle from a previous accident that occurred on September 25, 2025. There were no warnings before the vehicle uncontrollably accelerated at a very high speed. I have copy of the accident videos. Your platform would not allow me to upload the videos.

On February 11, 2026, the 2025 Tesla Model Y "vision autopark" system initiated an uncommanded high-speed reverse acceleration into a stationary yellow concrete bollard in a parking lot. The vehicle's vision-only parking assist hardware failed to detect a clearly visible, fixed obstruction and displayed a clear path on the system interface immediately before impact. No warning lamps, chimes, messages, or other alerts preceded the failure. The system provided zero indication of the imminent collision. The vehicle closed the distance to the bollard in under one second, exceeding human reaction time and making manual braking intervention impossible before impact. This failure mode — autonomous acceleration toward a stationary object without detection or warning — creates a severe crush hazard for pedestrians and property. The vehicle and its onboard data logs are available for inspection upon request. High-definition video evidence of the failure has been preserved showing the system ignoring the visible obstacle. The problem has not been confirmed by a dealer. The manufacturer's service center refused to inspect the vehicle or review data logs on the date of the incident despite an immediate in-person request. The vehicle has not yet been inspected by insurance, police, or the manufacturer. The failed component is the Tesla vision-only autopark system, including its camera-based object detection and autonomous vehicle control software.

Around 02/10/2026, all of adas functions of my 2022 Tesla Model Y has suddenly stopped working, and the rearview was just black. On 02/27/2026, Tesla service diagnosed the car and tole me that the car computer should be replaced and its total repair cost would be about $3,200. My car's mileage was 51,000 at the onset of the problem, so just passed the standard 50k warranty. My car has total loss of rearview camera (fmvss 111 violation) and loss of active safety systems (aeb/fcw), but Tesla refused to repair a federally mandated safety defect if I don't pay the full repair cost.

I am submitting this complaint regarding a newly leased 2026 Tesla Model Y premium rwd, which I took delivery of on February 6, 2026 from Tesla watertown, MA. I am a returning Tesla customer and entered this lease after test driving the same model on January 24, which did not exhibit any issues. Immediately upon driving the vehicle off the lot (approximately 12 miles), I noticed a persistent rattling noise from the front suspension area. The noise occurs over normal road conditions and has been present since delivery, significantly affecting the quality and value of the vehicle. On February 9, Tesla watertown evaluated the vehicle and later replaced both front upper control arm (fuca) mounts. On February 10, before repairs were completed, multiple safety systems suddenly disabled while driving, including regenerative braking behavior, traction and stability control, lane safety features, and automatic emergency braking, creating a dangerous situation. I returned the vehicle immediately and was provided a loaner. I picked up the vehicle on February 13 and was told the suspension issue was resolved, but the noise remained. I then sought a second opinion at Tesla peabody, where a master technician conducted a ride-along and confirmed the condition. He verified that the latest fuca parts had been installed and the front structural “pencil braces” had been removed per Tesla guidance. I was informed the vehicle falls into a known noise category affecting 2026 rwd Model Y vehicles and that there is currently no repair or engineering solution available. This defect has existed since delivery and remains unresolved after multiple service visits and component replacements. I have contacted Tesla regional leadership and customer support multiple times without response.

Rear-end collision. My Tesla impacted the rear of another vehicle at approximately 15–18 mph. No forward collision warning observed. Owner-provided data shows aeb status as sna. Impact is such that the car is totaled.

On January 20, around 9:35 am, phoenix time, I had the car in self-driving mode for a left-hand turn at the intercession of camino real and river road in tucson, arizona. A real-time view shows that it’s a tricky and dangerous left-hand turn. For the past 3 weeks, the car navigated it well, waiting until it was perfectly safe to do so. Today, however, the car moved quickly and unexpectedly into the center of river road, narrowly escaping a head on collision with a west-bound car, and then paused, squeezed in between west and east-bound lanes when I tapped the brake and took the wheel. Everything happened so quickly. I made the left turn into the east-bound lane, but, looking back, I don’t know how an accident didn’t occur, as traffic was still moving in east-bound lanes rapidly. There must have been enough distance between two cars at just the right time, that nothing hit me.

On January 17, 2026 the vehicle self-accelerated when put in reverse and crashed into a parked truck. This was the second time this occurred. The prior incident occurred on November 29, 2025 when backing out of the garage at our home. The new incident occurred the first time we put the car in reverse after receiving it back after repair from the prior accident (we received it on January 15. 2026 and this was the first time we drove it since then). We had driven the car forward with the full self driving feature turned on and engaged (part of the time and part manually) without incident. However when placed in reverse with the full delf driving turned on but not enagaged the car "took off. " it is only through good fortune no one was seriously injured or killed. Self acceleration in reverse only occurred after the vehicle was serviced by Tesla to repair the full self driving system which, at that time, would only engage intermittently.
