2022 TESLA MODEL Y Complaints

While driving in Autopilot, the car rapidly decelerated from 55mph to 35mph two times about 30 seconds apart, when two separate semi trucks were approaching me in oncoming lane, not crossing the lane or anything on a two way road. Seems to be well known as "phantom braking", but i just got the car yesterday and have put less than 30 miles on the car and already experienced this phantom braking twice. (Car currently has 60 miles on it) To note i did test drive a 2020 Model Y in December 2020 and did not experience this at all when using Autopilot on that car.

The vehicle control system intermittently commands hard braking at highway speed when there are no obstacles or vehicles nearby. This sometimes happens repeatedly over a period of several minutes and sometimes doesn't happen for weeks at a time. The braking and deceleration is so rapid as to result in difficulty controlling the car and potential hazard to cars following behind. After repeated "bug reports" to Tesla, nothing has changed. They issue a software update with a new game, but don't fix the hazardous problems.

While driving on a two lane highway at 70 mph on cruise control oncoming semi’s will cause the automatic braking system to drastically put on the brakes to 20 mph in 1 second, causing everyone in the car to lurch forward and pissing off the cars behind me to the point of almost rear ending me and causing road rage. I don’t want to neither be rear ended or shot at by these drivers behind me so cruise control is worthless and unusable on this dangerous car

As per many similar complaints, my Model Y while on cruise control will suddenly brake for absolutely no reason. I have almost been rear ended on the highway while traveling at 74 miles per hour. The car drops 20-40 MPH seemingly for absolutely no reason. I believe that this has been dubbed "Phantom Braking". Add me to the list!

At highway speeds using adaptive cruise or autopilot, vehicle suddenly brakes and veers towards the shoulder of the road. This occurs when a large vehicle such as a bus or semi is approaching from the opposite direction. Emergency break came close to causing a rear end collision today 2/17/22. Contacted Tesla service for investigation and repair.

While operating the cruise control on two-lane roads, the Tesla Model Y will frequently engage the emergency stop/warning function. NOTE: no autopilot has been used. There is no lane swerving or concern of the car approaching in the opposite lane or is the Model Y in any unsafe operating situation. This occurs in almost every driving situation with the cruise control engaged (two-lane roads) and has been documented with other passengers in the automobile. Obviously, this creates a panic situation for the driver and passengers while also creating a very unsafe operation for following cars. Multiple dates/times and weather conditions were mostly clear, i.e. no rain. As a note, we have owned a 2016 and 2018 Tesla Model S that did not have this problem.

Phantom Braking While using Autopilot (cruise control), my Tesla Model Y without warning slows the car from the speed limit (ex: 60mpg) down to half the speed or less. This usually occurs when the is a large approaching vehicle (semi or box truck) or when going around corners with a solid background (trees or large rocks). I assume this is because the car believes a collision is imminent and is trying to avoid it. Once the vehicle is past the car continues as if nothing occurred. The first time this happened was very scary and I ad no idea why it happened. Now I keep my foot resting above the gas pedal which keeps the car from severe braking action if you depress pedal right away. I mostly do not use cruise control on two lanes roads with lots of traffic for safety reasons, especially if there's someone following too close. My last trip of 60+ miles this probably occurred half a dozen times until I turned it off.

While using the Autopilot feature, the car applied the brakes many times for no reason. One incident was so severe that I decided to disable the autopilot feature for the rest of the trip so as not to put the drivers behind me in a dangerous situation.

The vehicle, while in Autopilot, has demonstrated "phantom breaking" on three occasions, two of which occurred on the same trip. The first was at night traveling on a highway with no vehicles in front of the car while the car was traveling 70 mph (the posted speed limit). (details on speed and mileage included below) This almost caused the car behind us to rear end our car. The second occurred during the day as we were traveling over a bridge on an off ramp at approximately 50 mph and both my children, who were sleeping, were unprepared for a sudden stop and complained about pain from the safety restraint system. The third was on a highway at 70 mph, and there was less of an effect as I was holding my foot above the throttle in the event this happened again. My wife asked that I no longer use this system while she or the children are in the car. There is no indication that the system recognizes an issue as the automatic dashcam did not activate, but it has activated in other situations where vehicles have made sudden movements in our lane in front of the vehicle. It is available for inspection. It has not been inspected by service yet. They are scheduled for February 22. No other inspections have occurred. There was no warning of this or messages of any kind to indicate the system was not functioning properly.

The car applies brakes for no apparent reason while using adaptive cruise control. This occurs frequently and without warning. I have become afraid to use cruise control because I fear it will cause an accident.
