Assist problems of the 2024 Tesla Model Y

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).

On [xxx], while operating my 2024 Tesla Model Y in full self-driving (supervised) mode, the vehicle experienced an uncommanded steering input leading to a collision. The vehicle was traveling at a very low speed of approximately 5 mph in a clear, simple environment. Despite this walking pace, the fsd software failed to identify a visible concrete curb and initiated a sudden, sharp turn directly into the obstacle without any prior warning or driver input. The fact that the system executed such a violent and erroneous maneuver at 5 mph indicates a fundamental failure in the neural network's object detection and path planning logic. If this logic failure had occurred at higher speeds or near pedestrians, the results could have been catastrophic. The local Tesla service center (watertown, MA) refused to conduct a physical inspection or a log review of the steering torque. They issued a repair estimate of $1,217. 26 while claiming 'no hardware fault codes' were present, thus ignoring the documented software malfunction. As a leaseholder of this vehicle with only 15,489 miles, I am reporting this as a significant safety defect that the manufacturer refuses to investigate.

Date & time: December 25, approximately 6:00 pm location: northbound I-880 between the mowry avenue and thornton avenue exits, fremont, CA weather & road conditions: heavy rain at the time of the incident. Road surface was wet with reduced visibility. Vehicle & system state: Tesla Model Y. Driver assistance / self-driving functionality was active at the time of the incident (traffic-aware cruise control / autopilot functionality). Description of the incident: while driving northbound on I-880 in heavy rain, the vehicle had been operating normally. Without warning, the vehicle appeared to incorrectly detect that it was drifting out of its lane and attempted to correct this perceived drift. Instead of a minor lane correction, the vehicle abruptly applied heavy braking and initiated a sudden and aggressive left steering maneuver. The car crossed approximately four lanes of traffic in the same direction of travel and continued rotating, ultimately performing an unintended u-turn while remaining on the northbound side of the highway. As a result, the vehicle came to a stop oriented against the direction of travel, facing oncoming northbound traffic. Immediately afterward, the vehicle unexpectedly began reversing at high speed without driver input, creating an additional imminent risk of collision with the outer highway wall (noise barrier separating the highway from adjacent residential areas). During this entire sequence of events, I was unable to regain control of the vehicle despite attempting to intervene. There were no vehicles immediately surrounding us at that moment. Had there been nearby traffic, this incident would likely have resulted in a severe or fatal multi-vehicle collision. Occupants: my wife and two young children were in the vehicle. The children were asleep in the back seat, secured in car seats. Outcome: no physical collision occurred. However, the incident caused extreme fear and distress, and we remain shaken by the event.

On 11/01/2025 at (12:15 pm]) my Tesla Model Y (VIN: 7saygaee8rf983245) was **parked in park/hold mode** in the winchester park parking lot, los angeles ,California the * navigation was set to an address in the center of the park**. The address on the address log of the car navigation system. The **Tesla gps navigation destination was set to a point marked in the middle of the park** (not a parking spot or road). **without any driver input** (no accelerator pedal pressed, no hands on wheel), the vehicle **suddenly shifted into drive, jumped the curb, and accelerated approximately more than 30 feet] into the park grass**. This caused **damage to wheels, and all the passenger side of the vehicle to impact with a large rock placed in the park **zero pedal input** — confirmed by driver and will be verified in Tesla server logs. No injuries. No other vehicles involved. **root cause**: **full self-driving (fsd) software / navigation system** incorrectly engaged **lane keeping assistance** while parked, triggering **unintended acceleration** via **speed control** logic. The car was on software update and suddenly disappeared. The car **autonomously drove itself** toward the gps point **from a complete stop**. Police report filed to lapd (case #251102900293). Tesla vehicle data report requested. **request NHTSA investigation** into * navigation-induced unintended acceleration from park**.

I would like to report a significant incident involving the auto-corrective steering in my vehicle. While driving on the highway, the steering wheel experienced a strong jolt, which I believe was caused by the auto-corrective steering system. This resulted in the vehicle spinning three times and ultimately coming to rest on the grassy center divider. Fortunately, no damage occurred at that time, and I initially attributed the incident to road conditions. I continued driving for approximately 30 minutes in rainy weather without further incident. However, a few hours later, during my return journey, the same forceful jolt to the steering wheel recurred about 20 minutes into the drive. On this occasion, the car spun 1. 5 times and subsequently collided backward with the concrete center divider. It is fortunate that no other vehicles were involved, given the heavy traffic and rainy conditions at the time. During both of the incidents, I had both hands on the steering wheel and was not able to correct steering due to the strong force from the steering wheel jolt. I did have a police report filed, but have to get number when I return home.

I would like to report an incident where Tesla fsd got confused by tire marks on a bridge deck and, soon after, by shadows on pavement. On both occasions, fsd steered the car across the double yellow before returning to its lane. There was no traffic and the car slowed down, so I let it play to see what would happen. Your site does not allow uploading videos so I'm providing youtube links to the videos showing the incidents. [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.

Navigation is frozen. No cameras work. No full self driving features work. No cruise control.

All cameras not working with latest software update - told need new ap4 computer on 2024 Model Y which is 2 months old. Tesla service advisor states - car is totally safe to drive with just mirrors till appointment in few weeks. No backup camera, navigation, battery life dying faster. It seems like a liability to me to drive this way and very negligent to me.

I was on [xxx] heading towards chicago and following the traffic. I started changing the line to pass the vehicle in front of me and suddenly my Tesla completely lost control and started drifting to the sides. I released the accelerator right away but it made it even worse. It seems that acceleration continues to happen that’s what made car to drift. Eventually car slowed down and I was able to make it to my line. I don’t understand why line assistance didn’t work to keep the vehicle stable, why after releasing accelerator the vehicle continued to gain the speed. It was sunny day and dry road. No foreign objects on the highway. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
