Adaptive Cruise Control problems of the 2024 Tesla Model Y - part 2

1st incidence: the car with full self driving mode self-changed to shoulder lane on fwy 10 west bound for unknown reason. I had to steer back to my lane to avoid hitting the fwy divider. 2nd incidence: with autosteer/cruise control mode, the car self changed to left lane, again I quickly guided the steering wheel back to my lane to correct the action and it caused a car accident.

My family and I were on i680 heading toward sacramento when the Tesla y suddenly braked. We were using autopilot and going around 70 mph. The car was trying to pull a full stop in the middle of the freeway! I quickly disengaged the autopilot and stepped on the pedal to speed back up. I'm guessing the Tesla saw a hazard on the road and put on the brakes. The problem is there were no hazards. Our safety was put at risk because we could've been reared, and it could've caused a pileup. Luckily, it was early Sunday, and there weren't a lot of cars on the road. We stopped using the autopilot immediately, so the problem has not been reproduced. We have an appointment with Tesla in four days. I will be reporting the incident to them. I'll ask for an inspection then. There were no warning lamps or other symptoms prior to the sudden braking. It was a very jarring experience. I have my kids in the back seats.

I was driving down the highway with my wife and baby at about 65 mph. I was using regular cruise control with no one in front of me when all of a sudden, the car braked extremely hard. Luckily, the car behind me was far enough back to switch lanes and pass me. If it was closer, this could have resulted in a highway accident. The car stopped braking maybe around 30 or 40 mph. I may have it recorded in the Tesla camera system since I pressed the save button approx 4 min after it happened. I also scheduled a service call with Tesla that will hopefully happen on may 7th.

My wife and I purchased a Model Y 2024 just a few weeks ago. We have had multiple experiences when using cruise control where the car inexplicably slows down rapidly when there are no vehicles in front of us decelerating.

While using autopilot with beta self driving installed and stopped at a traffic light, left or right turn traffic signal turning green causes car to move into oncoming traffic (moves straight through intersection).

While driving to work, using fsd, the autopilot steered me into the path of an overtaking vehicle moving at about 20 mph faster than my vehicle. By quickly taking over steering and speed control, I was able to avoid a collision. A couple miles further down the road, the car could not decide on which exit lane to use, and weaved between two possibilities, probably alarming and angering drivers behind me. Again, I had to take over control. Taking over speed and steering control was necessary two more times in my 25 minute trip, most of it on well-marked multi-lane highways. Of the four incidents, only one would have resulted in a serious high speed collision, had I not taken over very quickly. Having coached robotics competitions, and piloted aircraft with autopilot, it is my opinion that the fsd (supervised) software is at alpha stage in development (not yet up to beta stage, at which it could be safely released only to select skilled drivers, with suitable disclaimers and warnings) . At delivery, no introduction to the car's controls is provided, so customers are on their own regarding finding out, by trial and error and the occasional potentially lethal collision, how to safely drive the vehicle with fsd engaged. The manufacturer should be required to instruct all customers on the very high level of vigilance required to operate with fsd engaged.

While using autopilot or beta self-driving - when a minimum speed limit sign is detected on I-75 in georgia, the system usually reduces to the speed of the vehicle to posted minimum speed (40 miles an hour) instead of maintaining current speed limit.

We purchased a 2024 Tesla Model Y approximately one month ago. We have experienced multiple occurrences (10-15) when traffic adaptive cruise control was engaged. Our car suddenly braked for no apparent reason. Last night, while traveling at 65 mph, on a four lane major highway, it happened again, nearly causing a rear end collision. We are hesitant to use cruise control because this feature (t. A. C. C. ) is built into cruise, no way to separate it. After researching online, we discovered this is not a new or unusual event and has been reported by hundreds if not thousands of Tesla owners, dating back at least 3-4 years (if not longer). There are no warnings prior to the event. The car suddenly slams on brakes in what seems to be a “panic stop. ” we understand a record of these occurrences are recorded and available from Tesla at your request. We have registered a complaint with Tesla as well.

Car decelerated drastically to a low speed when driving on the highway using cruise control.
