2023 Tesla Model 3 Complaints

On XXX at around 3:30 PM EST, I was driving my 2023 Tesla Model 3 on [XXX] about 10 miles outside of [XXX]. I had the adaptive cruise control set at 75 mph. I was driving in the right lane of the two available lanes of travel in that direction. I noticed an unattended car on the right shoulder about a 1/4 mile up the road and continued my drive as normal. The car was at least 5' to 6' off the highway. As i got about 30 yards from the car, my car suddenly slammed on the brakes automatically, which forced me to react in a corrective manner. Thankfully there was nobody behind me or the severity of the braking would have likely caused a rear end collision. To my understanding, this phantom braking is a known issue with Teslas, so I wanted to document my experience to add to the record. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On 8/24/2026 at approximately 12:02pm, my 2023 Model 3 was parked in my assigned space in a covered apartment carport, with a concrete support pillar approximately one to two feet from the passenger side. I entered a destination and activated FSD (Supervised) from Park, a Tesla-designed feature. Vehicle telemetry recorded in the dashcam clips shows FSD shifted into Drive, activated the right turn signal, turned the steering wheel to near full right lock, and accelerated to 3 mph, contacting the pillar with the passenger mirror and front door approximately 1.5 seconds after first movement. No accelerator or brake input was recorded from me before the collision. I applied the brake within one second of the impact beginning, and FSD disengaged. The pillar was within view of the vehicle's side cameras throughout. No warning was given. Damage to the passenger door; no injuries. Dashcam video with telemetry overlay and photos available.

I am writing to report several safety incidents that occurred while using Full Self-Driving (FSD) mode on my 2023 Model 3. Below are the details of the specific behaviors observed: - Right turn on red almost crashed into an oncoming car from the left - Hard emergency brake due to a bird that was in the opposite lane - Additional emergency brake around 10 seconds later for no reason - Running a red light by more than a second

Two separate incidents occurred on July 10th and July 12th 2026 involving adaptive cruise control. While adaptive cruise control was engaged my car slammed on the brakes for no reason. There was nothing in the roadway to cause abrupt braking. The second time it occurred my car was close to being rear ended by a vehicle driving behind me. I took the car which is still under warranty to Tesla who confirmed there is a known firmware issue. No time frame was provided as to when the issue will be fixed.

Whilst driving on highways which feature multiple speed limits - eg. 70 cars, 65 Trucks, 60 Buses. If full self driving more or when in adaptive cruise control - the car systems fail to recognize the restriction linked to the lower speed limits. As a result, you can be driving on Full Self Drive at 75mpm, the car sees a 65 followed by a 60 speed limit (neither applicable to cars), but the car brakes hard dropping the speed from 75 to 62 almost instantly and, on more than one occasion, a closely following car has almost collided with me. Until such time as the Tesla system can recognize the 'sub text' on a speed limit - the FSD and Adaptive cruise should not be certified. I also drive a BMW i4 and this reads all signs correctly, only applying those applicable to a car to the vehicle.
