Air Suspension Failure - Damping Control Disabled (Code TAS_a313)" Description: "Vehicle is 2 days old. Suspension control module lost communication with CAN bus. Vehicle is in 'fail-safe' mode. Tesla Service Center has refused to assist. Safety risk due to loss of adaptive ride control." Manufacturer Response: "No response / Ignored."

The vehicle's Indirect TPMS showed a "Pressure Sensor Fault (may clear next drive)" without issuing any "Low Tire Pressure" alert. On July 20, 2026, while driving, the rear right tire lost pressure and disintegrated over a 10-minute drive. Despite severe tire failure that triggered multiple safety system alerts (Traction Control, Stability Control, Automatic Emergency Braking, and Lane Departure Avoidance disabled), the vehicle software FAILED to issue a critical "Do Not Drive" command or explicit "Flat Tire" warning. Furthermore, the official Tesla App automated response advised that "Most alerts may resolve automatically on your next drive," encouraging continued driving. This total absence of critical emergency alerts and misleading system guidance created an extreme, life-threatening road hazard and resulted in severe tire and wheel destruction.

On many occasions in the year we have owned our Tesla Model Y, we have experienced sudden, unexplained braking while using the Traffic Aware Cruise Control (TACC) feature. We have experienced several near-misses of cars or semi tractor trailers rear-ending us. These incidents were avoided by quick reaction of the Tesla driver to override the TACC. I have documented several incidents using the dash camera on the car and have assembled a spreadsheet of times and places of occurrence that correspond to the videos. One Tesla service representative dismissed my complaint by saying the feature is working as designed, so nothing further was done. A representative at a different dealership acknowledged that it is a known characteristic in the current firmware and they expect it to be addressed in a future software update. As I said, we have been experiencing this for over a year. It is a clear safety hazard, not only for the Tesla driver and passengers, but also for any vehicle following who has to react to the sudden, unexpected braking.

Tesla's FSD system has ZERO opportunity for the driver to adjust what the car believes is the speed limit. My car often has no idea what the speed limit is. More often than not, it believes the speed limit is lower than it actually is, by as much as 30 MPH. This causes the car to impede traffic if I do not intervene. I can press and hold the accelerator to force the car to drive the speed limit, however I am then faced with a warning that the car will not automatically brake in an emergency. I run my car in "Sloth" or "Chill" 99% of the time to prevent speeding (something you should actually enforce), and this is really where the issue becomes somewhat problematic. If I'm on a 55 MPH road driving 55-57 and the car suddenly decides the speed limit is 30, in sloth, it will decelerate aggressively, making people behind me think I'm nuts... could potentially be dangerous. Recently I was on a "new" road into a campground, a couple days after school ended and there were children around, the speed limit on the road is posted at 20... the car said [XXX], and proceeded to accelerate aggressively of course I terminated the FSD session and just drove the car myself. But no matter which way it is, it's insane that I cannot adjust the speed limit to whatever the speed limit actually is. I own this car, and I pay for FSD for one reason, I'm getting older [XXX], and my driving skills and reflexes are not what they used to be. I'm spending my money to increase safety... please insist that Tesla allow us to adjust the speed limit, or provide a way to get them to do it in a timely manner. I report these situations to Tesla often... not once have they adjusted whatever they use in the background... same problems on the same roads over and over and over, day after day. Please force them to do the right thing! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Lane keeping assistance turns on with every drive no matter how many times I set it to off. Where I live there are many potholes and poorly paved roads, along with poorly marked roads. As I am swerving around obstacles the car will fight the steering inputs I am giving it, trying to steer me back into whatever I was avoiding. This is a safety issue, and is not a problem on our older Tesla model 3 performance, as once that vehicle is set to off, it stays off. Now, as I start every drive I am navigating through a couple screens to turn off this "safety" feature.
