Using Tesla FSD 14.3.3. It began raining hard, causing standing water to pool on the road. The standing water was making the car lose traction and started sliding within the lane, it did change its speed or driving to account for the rain. FSD was doing over the speed limit and would not slow down slower than the speed limit. Changing the Tesla speed profile from Standard to Sloth slowed it down to exactly the speed limit but no lower. At this point the car could not maintain its lane, I feared for our safety, so I had to disengage FSD to regain control of the car. Tesla have removed all methods of allowing the driver to maintain accurate speed control of the car and it often ignores speed limit signs, which means it is traveling too slow or too fast for the currently posted speed limit.

This is a safety concern for visibility. How can a brand new, barely used windshield crack like this? There are no rock chips and it has barely been driven to fall as wear and tear on the vehicle. This is not okay and incredibly unexceptional for vehicle standards. This vehicle spends 90% of its time in a garage. I have contacted my insurance company.

While operating a 2026 Tesla Model Y on Full Self-Driving (FSD) Supervised, the vehicle's vision-based lane-keeping system failed on an unmarked residential road. At approximately 26 MPH, the vehicle approached a blind crest of a hill. Due to the lack of painted center lines, the FSD software miscalculated the road geometry and drifted significantly into the center/oncoming lane exactly as it reached the top of the hill. This lane departure created an immediate, severe safety hazard, as it placed the vehicle directly in the path of potential oncoming traffic with zero forward visibility over the crest. Due to the critical lane positioning error, immediate driver intervention was required. The driver took manual control of the steering wheel to force the vehicle back into the correct lane, causing the FSD system to instantly disengage. Simultaneously, the driver applied manual braking to reduce speed drastically down to 10 MPH to safely clear a resident working on the right shoulder and stabilize the vehicle. Prior to the failure, there were no warning lamps, error messages, or symptoms indicating the system would fail to maintain proper lane positioning. The system appeared to be functioning normally up until the crest of the hill. The vehicle and its Autopilot/FSD components have not yet been inspected by Tesla, police, or an independent service center following this specific event. The vehicle remains available for inspection upon request

On XXX at approximately 9:30am, my 2026 Tesla Model Y suddenly accelerated without driver input while parking at The Center at [XXX], [XXX]. Vehicle surged forward unexpectedly. I immediately applied brakes. No warning messages appeared before or during the incident. Vehicle struck parking lot curb. Police responded and vehicle was towed. Physical evidence including tire drag marks and vehicle debris remain at scene. Requesting full EDR data log preservation.

The right rear aluminum rim on my 2026 Tesla Model Y (Juniper trim) has a crack in it, causing a slow air leak. I discovered this issue approximately 2 weeks ago when I noticed the tire was repeatedly losing pressure. I have had to refill air in the tire every 2-3 days. The crack is located on the rim itself, at the sidewall area between the rim and the tire, where air bubbles can be observed escaping when submerged or sprayed with soapy water. I have no recollection of hitting any potholes or curbs that would have caused this damage. The rim appears to be defective from the factory. The vehicle component (rim) is available for inspection. No crash, fire, or injuries have occurred at this time, but continued driving poses a safety risk due to the potential for a sudden tire blowout. Photos and a short video documenting the crack and escaping air are available.
