Every time I press, my horn and error pops up that my cameras are unavailable, and that features may be restored on the next drive also it sends an error that my regenerative brakes are also out and will be restored on the next drive. It does this consistently every day which causes a safety hazard when driving my vehicle.

On September 12, 2026, at approximately 2:05 PM, while operating on Full Self-Driving (FSD v14.1 Lite) on Hardware 3 (HW3), the vehicle experienced a critical, unprompted loss of path control. While traveling on the highway, the vehicle sharply veered off the left side of the roadway, caught air, and violently impacted an emergency barrier, resulting in the destruction of 9 steel poles and causing physical injuries to both the driver and front passenger. Despite the severe frontal impact and structural collision, neither the front nor knee airbags deployed, raising serious concerns regarding the vehicle's crash-sensing algorithms, structural impact detection, and restraint system integration under this software version. This incident highlights major safety risks associated with running computationally heavy FSD stacks on legacy HW3 architecture: 1. Uncommanded Steering Deviations: The system abruptly executed a violent, unprompted hard turn away from the path of travel, indicating severe lane-detection or path-planning failure. 2. Restraint System / Safety Failure: Critical secondary safety systems (front and knee airbags) failed to deploy in a high-impact structural collision involving multiple steel barrier poles. 3. Hardware Constraint Risks: The compounding computational and thermal load on HW3 hardware running v14.1 Lite continues to manifest in erratic vehicle control, latency, and hazardous tracking behavior. This severe safety defect requires an immediate federal investigation into both FSD trajectory control on legacy hardware and secondary restraint deployment failures.

Tesla rolled out FSD 14 Lite to hardware, including to my vehicle and it’s become extremely unsafe.The past several days the vehicle will suddenly slow down/break causing people to almost crash into me, make sudden and indecisive lane changes, and constantly rocking the steering wheel left and right. I hope someone takes this seriously and has Tesla revert back to the old software or make changes before someone is killed.

I was using Full self driving (FSD), but I notice the autopilot gets "impatient" when (correctly) stopped for a "long" period of time (~2 minutes), but will then try to proceed in dangerous conditions. 1. I had FSD engaged while waiting to make an uncontrolled left turn. The street I'm turning onto is busy, so both lanes are going at a steady pace. After about 2 minutes of waiting, the autopilot decided to make the left turn while BOTH directions had cars approaching. It turned towards a motorcyclist (which might be why it thought the lane was "empty"), and cut off a rather large car behind the motorcycle which almost caused a collision. I was honked from both sides (rightfully so) and put in a very dangerous position as my car was now stopped in the middle of the row of both lanes. 2. I was at a red light intersection with no traffic coming from either side with FSD engaged. After about 2 minutes of waiting, the car tried to go on its own while the light was still red. After manually stopping the autopilot, the light naturally turned green a few seconds later.

Tesla FSD on HW3 vehicles has become very unstable. Users complain the car ping pongs within the lane and occasionally will steer onto the left or opposite lane. This seems to have happened after a recent update between Feb/March 2026. Growing reports of the same issue reported on Reddit. Ping pong tesla fsd Sources: r/TeslaFSD, r/TeslaLounge, r/TeslaSupport Tesla FSD Ping Pong Effect Software Updates Recent Updates: Many users have reported that the ping-pong effect started after recent software updates, particularly 2026.8.6 and 2026.14.3. "Yes, this started for me after the update to 2026.8.6 and continued on 2026.8.6.1" HW3 Issues: Some users with Hardware 3 (HW3) have noted that FSD has become unusable due to this effect. "I'm HW3 Software 2026.14.3 FSD Software V12.6.4 Driving on the highway is completely unusable and would result in a crash if I kept it on." Troubleshooting Steps Camera Calibration: Several users have suggested recalibrating the cameras, which can sometimes help. "Try a camera housing cleaning and a camera calibration" DAS Reset: Performing a Driver-Assist System (DAS) reset has also been recommended. "Also reset the DAS" Cleaning Cameras: Ensuring the cameras are clean can improve performance. "Ask SC or mobile service to check camera alignment AND clean the front cameras, and recalibrate cameras." Hardware Issues IMU/Gyroscope: A few users have been told by Tesla service that the issue might be due to a failing gyroscope/IMU in the HW3 Autopilot computer. "The tech told me it might be a failing gyroscope/IMU inside the HW3 Autopilot computer." HW3 Replacement: Replacing the HW3 computer can be costly, and some users are considering waiting for a HW4 retrofit. "Their solution is to replace the entire HW3 computer — quoted around $2,500–$3,000." User Experiences Ping-Ponging on Highways: Many users have reported the ping-pong effect specifically on highways. "While using FSD on higher speed interstates (multiple) my car acts like a

There was a failure of a rear camera to detect the proximity of a closed garage door when in reverse in a driveway. The result was hitting the garage door and damaging the garage door as a result. This could be dangerous as there was no warning on the backup camera screen and no audible warning. This was a very expensive repair given the garage door was a unique color and design.

I was involved in a collision while driving my 2019 Tesla Model 3. The incident occurred on April 2nd 2026 in [XXX] Prior to the collision, the vehicle was operating normally The crash resulted in damage to the front driver-side of the vehicle, including a destroyed headlight and body panel damage. At the time of the incident, weather and traffic was light and normal. The vehicle was set and supposed to head straight when suddenly at the intersection it jerked right and headed straight into another vehicle. I attempted to take control but was unable to due to resistance on the wheel and how quickly the incident occurred. There was no warning or emergency braking which should've also been expected from my tesla. I am submitting this report to document a potential safety concern and request review.

What component or system failed or malfunctioned, and is it available for inspection upon request? The steering system failed due to corrosion and water ingress affecting both the steering rack and the associated steering wiring harness. These components were replaced by Tesla and are no longer available for inspection. How was your safety or the safety of others put at risk? The steering system is a safety-critical component. Corrosion and water intrusion created a risk of reduced or sudden loss of steering assist while driving, which could lead to loss of vehicle control and increase the risk of a crash. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Tesla service confirmed water ingress and corrosion affecting the steering rack and wiring harness and performed a full replacement of both components. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The vehicle and steering components were inspected by Tesla at a Tesla Service Center, which identified water ingress and corrosion as the cause of failure. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The vehicle displayed steering-related warning messages prior to repair, including reduced steering assist alerts, which prompted inspection by Tesla service. The warnings appeared shortly before the repair was performed.
