While using Tesla's Full Self-Driving (Supervised) software on the Pacific Coast Highway (PCH) and other highways, the vehicle’s automated steering system repeatedly malfunctions by failing to maintain lane centering. Specifically, the car drifts or actively steers across double yellow lines into the lane of oncoming traffic. This issue is a persistent failure of the Advanced Driver Assistance System (ADAS) and Lane Keeping Assistance. The vehicle has attempted this maneuver multiple times at [Approximate Speed, e.g., 40-60 mph], requiring immediate and forceful manual steering intervention to avoid head-on collisions with oncoming vehicles. The system provides no warning chimes, error messages, or "Take Over Immediately" alerts prior to crossing the lines; it appears to perceive the oncoming lane as a valid path or fails to recognize the double yellow boundary entirely. This has occurred during [mention conditions: e.g., bright daylight with high glare / night time]. The vehicle is equipped with Hardware 3.0 (HW3). I believe the 1.2-megapixel camera suite or the processing power of the HW3 computer is insufficient to safely navigate the geometry of the PCH or any roads within mountains/hills. I have attempted to "Clear Calibration" and performed system resets, but the life-threatening behavior persists. The vehicle and its internal data logs are available for inspection. I have also sent "Bug Reports" via voice command to the manufacturer immediately following these near-miss events.

I was driving on the highway when the touchscreen lit up with multiple error messages including: - Steering assist reduced (Steering may require increased effort) - Traction control disabled (Drive with caution) - Stability control disabled (Drive with caution) - Parking brake functions degraded (Parking brake may not apply or release) - Lane Departure Avoidance features unavailable (Features may be restored on next drive) Also, the speedometer changed to 0 (while we were going 70 mph). When I pulled onto the next off-ramp the steering was very heavy and the regenerative braking was not working. Pressing the brakes (even slightly) felt like the ABS was pulsating. This was extremely dangerous and easily could have resulted in a serious accident in heavy traffic or if the road had not been straight. It was a rental car so I have not seen the car since the rental company towed it away. I have not heard from the rental company about the car's status or their findings. Prior to the catastrophic failure of multiple systems, there were two other warnings messages: - Left front fender camera blocked or blinded (Clean cameras or wait to regain visibility) - Autopilot safety/convenience features unavailable (Features may be restored on next drive) These had been coming on and off for a couple hours but I had assumed they were due to driving through heavy rain.

Making a 90 degree right turn at an intersection traveling approximately 15 mph, my steering wheel suddenly got very stiff and unresponsive. This caused me to travel into the oncoming lane of traffic before wrestling the very stiff steering wheel back under control. This condition persisted for the rest of my drive home, accompanied by “Steering assist reduced” and “lane assist keep unavailable” error messages. This incident luckily did not result in an accident but easily could have if it happened at the wrong moment.

The steering wheel locked up while I was driving. I was driving on a country road and the road didn't have any painted lane stripes and the car got a lane departure warning and the steering wheel pull me hard to the left, I almost got out of the road and on the way of a incoming vehicle, I break and pulled hard to the right and managed to pull to the side. When I got into a complete stop I checked all the settings, I turned off the late departure Assistant and the steering wheel was still locked. There is no on or off button on the car so I walked away from the car, the car locked and unlocked to get back in and the steering wheel was back to normal. It was very scary, lucky I was driving slowly and I wasn't around heavy traffic.

Something occurred with the steering, automatic braking, or lane keeping assistance on [XXX] at approximately 6:35am while I was driving my 2022 Tesla Model 3 Long Range North in the carpool lane just south of [XXX] in Sandy Utah. The roads were a little slick so was proceeding cautiously at around 65 MPH when the car turned to the left slightly, then immediately to the right, which caused it to do a 180 degree turn in the same lane, I wasn't sure what was going on as the car felt like it was driving itself. Before I knew what was happening, the car then veered to the East across three lanes of traffic while driving backwards, it then stopped just as it was struck in front of the wheel on the front drivers side by a two trailer semi-truck which spun the car around. Luckily I was conscious so could slowly limp across the last couple lanes to the right side of the road where I called 911. I've driven all kinds of cars in all kinds of conditions and in many countries in the nearly 32 years I've been a licensed driver and have never lost control of a vehicle, I'm sure the steering or lane assist was trying to intervene so must've somehow inadvertently caused the crash! It's only through the grace of [XXX] that I'm still alive to tell about it! Also, none of the airbags went off even though the impact from the semi was very jarring!

I was traveling on Interstate 40 in Arizona in a 75 mph zone with my cruise control set at 77 mph. Suddenly and without warning the car’s emergency braking system activate despite nothing being in the roadway in front of me and no cars ahead at all. I had to take evasive measures to avoid being hit from behind by a semi truck. Approximately 10 seconds later I began receiving error messages for several systems including emergency braking, traction control, steering alignment, lane departure, stability control, cruise control, vehicle hold, and regenerative braking. In addition, other systems were not working, such as an alert tone for when traffic lights turn green would activate indicating the driver should go even if there was a car in front that has not moved. The car is currently at Tesla being evaluated, however I really don’t think these cars should be trusted.

my brand new tesla model 3's adaptive cruise control is unsafe and unusable while driving on a two lane highway, I took a 500 mile road trip last night and the entire time i was experiencing random hard breaking while driving. I have stopped using it since but it has me worried about my safety as well as other when using this program. I am also having issues with my lane keep assist activating despite it being fully disabled in settings, it pulls my steering wheel back into the lane when i am changing lanes, even with a turn singal, and the computer system screams like crazy telling me im departing my lane. This almost caused me to crash one time as I had to overcome the computer pulling me back into the lane I was already in, despite me intending to change lanes.

My Tesla Model 3 was on cruise control (not autopilot) and braked suddenly. I was driving 75 MPH and the car braked to 50 MPH in a matter of one or two seconds. It was a perfectly clear day and there were no cars in front or behind me within a mile distance. There were no objects on the road and absolutely no reason to brake so suddenly. The vehicle was only in cruise control. Lane keep assist (autopilot) was not enabled. Again, there was absolutely no reason to brake. Had a car been behind me, it would have been very dangerous and could have caused an accident. The car braked on its own quick enough that someone behind may not have had time to brake. Cruise control stayed on throughout the entire incident. I turned off the cruise control and took manual control and was able to drive without any issues. This is a serious safety issue that needs to be addressed by Tesla. I feel unsafe using any of the ADAS systems. Also, the car has 1K miles on it and this has occurred three times. The other two times when it occurred the car was in autopilot. All three time the car was driving on the highway in Texas and Oklahoma.

While driving at high speed on a freeway the car started braking without driver touching the brake pedal. Adaptive cruise control and lane departure were on. Fortunately no one was following close or it could have cause a serious accident. This happened twice on one day.

The autopilot applies the brakes when there is no obstacle in front of the car. One example - I was driving @ 60 mph on an entrance ramp from I-10 to SH 99 with the cruise control engaged but not the full autopilot (no lane keeping assist). There was a spot in the highway approximately 50 yards ahead where there was a slight dip and oil and lubricants had made a dark spot on the roadway approximately the size of a small car. Without any input from me the car slowed quickly from 60 to @ 30 mph. Fortunately no one was close behind me. Another example - I was driving @ 70 mph on SH 99 with the autopilot engaged. As we approached a gentle left hand turn the system apparently picked up the concrete guardrail as an obstacle and braked the car from 70 mph to @ 40 mph. As the autopilot continued the turn and maintained the lane the car sped back up to 70 mph. No one was behind me but there were cars in the lanes next to me that reacted when my car slowed down and sped up. My car is a 2022 Tesla Model 3 Dual Motor Long Range. It does not have the full self driving option.
