    Correction: Retrofit SBR in OCS Equipped Front Passenger Seat - Remove and Replace. FIRST ROW - SEAT BELT REMINDER SENSOR BOX CLIP (1130363-00-B), FIRST ROW OCCUPANCY SENSOR(1099592-00-F) FIRST ROW SEAT HARNESS ASSEMBLY - RIGHT HAND (1489060- 03-G). This car has 69k miles and I'm informed this is out of warranty and has a cost of $696.75 to repair on a car that is less than 4 years old. Saying the sensor failed is not accurate as the error does not exist unless there is someone in the passenger seat which tells me the sensor is working somewhat. Tesla will not inform me of what will and will not work in the event of a collision but that these items need to be replaced to ensure safety of occupant's. I am skeptical since safety is your number one concern and should be the concern of every auto manufacturer. Unless damage by the owner specifically, how and why is this not covered for the life of the vehicle?

    While using traffic aware cruise control or autosteer, the car occasionally detects a nonexistent person in the center of the lane I’m driving in, the proceeds to slam on the brakes when no hazard exists. It seems that tire markings in the road and certain lighting conditions cause the car to think there is a person in the road. Additionally, when driving on a highway with rolling hills, the car detects a forward collision alert and hits the brakes and disengages the autosteer. Both of these could cause a rear and collision at highway speeds. The dealer has claimed that the cause is functionally normally and I already tried to get it serviced but the car continues to have these issues. I do have video evidence of the car slamming on the brakes and detecting a forward collision.

    While backing up, the rearview camera feed occasionally displays a noticeable delay, which prevents objects and pedestrians from appearing in real time. This lag creates a significant safety risk, as the visual information on the screen does not accurately reflect the vehicle's current surroundings. Additionally, the display on the left side (vehicle proximity visualization) does not match the camera view or actual situation, further contributing to confusion and potential danger when reversing. This issue persists despite software updates and appears to be a systemic flaw that compromises driver awareness and vehicle safety. Cross-traffic alert appears impacted.

    The interior rearview mirror exhibits tiny bubbles around the edges and streaking or cloudiness within the layered structure of the auto-dimming (electrochromic) mirror. The problem has occurred in multiple potential replacement mirrors, indicating a design or manufacturing defect. The issue first appeared as small bubbles around the outer edge, then progressed to visible streaking and cloudiness within the mirror surface. These symptoms impair rear visibility, particularly at night or in bright light conditions, when glare and distortion are most severe. This creates a safety hazard by: 1) Obstructing the driver’s clear view of approaching vehicles. 2.) Reducing reaction time Increasing the risk of rear-end collisions or unsafe lane changes. 3.) It compromises overall driver situational awareness, especially in high-speed or congested traffic environments. The defect is not isolated to a single part. Defective mirrors have been retained for documentation and are available for inspection. Mirror replaced with same part number under limited warranty, but the replacement option showed same failure, suggesting a broader defect not yet addressed by a permanent fix. Additional replacement parts offered show similar defects.

    Incident Details: • Date of Incident: [XXX] • Time: [XXX] • Location: San antonio, Tx • Weather/Road Conditions: Clear, dry highway; 90 F • Speed: 60 mph; • Description: while driving my 2021 Tesla Model 3 with Full Self-Driving (FSD) software version 12.6.4 engaged, the vehicle unexpectedly changed lanes without my input, likely due to the Auto Lane Change feature. Immediately after, it braked hard for and unrecognized slowing traffic ahead. This sudden jolt caused immediate pain in my upper back, neck, and chest, which persists. I believe FSD misjudged traffic patterns or road conditions, a known issue with v12.6.4 based on online reports. The incident occurred in heavy traffic and no crash occurred, but the abrupt braking posed a safety risk and caused injury. I’m unable to see a doctor today but plan to soon for a diagnosis. This is a serious safety concern, as FSD’s erratic behavior could cause collisions or further injuries. Injuries: Yes, back, neck, and chest pain caused by sudden braking. No medical diagnosis yet; planning to see a doctor soon. Crash: No Fire: No Police Report: No accident Attachments: i have video INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    On [XXX] at approximately [XXX] on [XXX] in Oakland, CA, I was intending to park the car on the street at the curb. As I started to pull to the side of the road to park, the brake suddenly fully engaged, bringing the car to an immediate complete stop. My foot was not on the brake at the time. There were no obstructions of any kind in the road or in front of the vehicle. No warning sounds, messages or lights were activated before, during or after the incident. The incident caused no injuries, because of the low speed at the time, just a sudden jerk forward. However, if the event had occurred at a higher speed, some kind of injury would have been likely. I am also reporting the incident directly to Tesla. There has been no testing or inspection of the vehicle. The vehicle will be made available for inspection or testing if requested.

    Attempting to park. Slowly inching forward while turning left. Vehicle accelerated. (Sudden Unintended Acceleration: SUA) Vehicle jumped a curb, bounced off a tree, dropped off the curb before comping to a stop. Internet search shows other similar reports; attributed, by Tesla, as pedal misapplication. This was not "pedal misapplication". I am not looking for anything. But NHTSA should increment occurance counter by 1. Tesla has a problem. Electrical or Mechanical...do not know. They have also lost me as a customer. The car will be sold. I have video...mp4

    my 21 M3P 27K miles threw BMS_a079 I've never used a supercharger and rarely charge over 80% mostly charging at work on lvl 2 & occasionally at home on lvl 1 vehicle will no longer charge I've tried 2 Button reset and HV disconnect no help. 27k miles seems unreasonable for a battery malfunction on a vehicle that has been cared for meticulously.
