2022 TESLA MODEL Y Forward Collision Avoidance Warnings Problems

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.

When using autopilot, the car brakes at all sorts of non-events incl curvy roads, shiny puddles, undulations, trucks going the other way without incident, and more.

Phantom breaking happens consistently when cruise control is engaged. The phantom breaking happens every day and multiple times a day. Whether it be on a multi lane freeway or a two lane highway, serious breaking occurs and often can be quite dangerous when cars are following behind our vehicle.

Phantom breaking. While on traffic aware cruise control, we have experienced several episodes of sudden hard breaking for no reason. Fortunately, no one was following closely. The car is available for inspection. Hard sudden unexplained breaking increases risk of rear end collision. No inspections have been performed. But I did discuss it with a Tesla mechanic. He was familiar with the problem and stated that even tho my vehicle does not have radar, it has the bracket and the wiring so it can be installed later. Supply chain issues was mentioned as a possible reason for its absence. No warnings prior to breaking. Simultaneous with phantom breaking is audible alarm. This last occurred yesterday Feb 10, 2022 mid morning. Good road conditions.

When coming home from the dealer, it phantom braked twice. I thought at first maybe it was a shadow across the road. There was a software update the next day, and I hoped it was fixed. It was raining lightly and there wouldn't be any shadows.. a box truck came toward us in the opposite lane and it panic braked. As soon as I turned the cruise control back on, a semi came toward us, and it panic braked again. I've been afraid to use the cruise control since then.. if someone was inattentive behind me, they would probably hit me. Tesla says they have checked the systems on my car remotely and there is nothing wrong with it. (!!) It now has 200 miles on it.

The car does phantom braking and creates dangerous situation on the highway. Happened many times on cruise control and autopilot.

Phantom braking when on cruise control

I was driving on the highway using Autopilot, and the brakes engaged very suddenly without any warning signal nor was there anything in front of my car. (Aka “phantom braking” event).

Multiple occasions while using autopilot on 2 lane roads when semi trucks are coming in the opposite direction the Tesla will brake hard saying impending accident when the semi is staying in its lane ….it happens about 80 percent of the time. It’s so bad I will not use this feature till it’s fixed as it’s dangerous

The car is experiencing PHANTOM BRAKING. The vehicle incorrectly detects objects and brakes vigorously dropping speed really quickly. If traffic is following we could easily get rear ended. This happened over 10 times in a 100mile journey.

Phantom breaking. When I am driving my vehicle in both cruise control, and autopilot I experience these very very dangerous symptoms. On 2 lane highways is the worst. When I see a semi truck oncoming my vehicle will go from the 65MPH speed limit and SLAM on the brakes sending me from 65-15 MPH immediately. Have almost been rear ended 10+ times in 3,000 miles of owning the vehicle! This is the most dangerous machine I have ever driven. Tesla needs to fix this. It has to do with them removing the radar and going to camera only autopilot. My other older teslas with radar do not do this. There’s no on at Tesla to talk to other than to tweet at Elon musk on twitter and hope he sees it. Ridiculous.

With AutoPilot engaged both during the day and at night, though more frequently at night, and driving on two lane highways, the car automatically brakes sometimes very hard causing your neck to snap forward, whenever it detects oncoming traffic. This is amplified at dusk and at night. There is no warning or time to override this. Making the vehicle dangerous to driver, occupants, or cars travelling behind the Tesla. Tesla claims that this is a known issue, but other brands with similar safety mechanisms do not have this "Phantom Braking' condition.

While adaptive cruise control is engaged, the system seems to incorrectly interpret a potential head-on collision and brakes hard and usually plays the alarm sound. I've had this car around two months and have found that this usually happens on a two-lane highway while traveling at 50-60 mph and when a box truck or larger is approaching from the opposite direction. It's worst when the sun is bright and casts a shadow of the truck and trailer across my lane. But it occasionally happens at night and when conditions are cloudy. I have to keep my foot over the accelerator pedal and force the car to keep speed, especially if there is a car close behind me. Otherwise, I'm scared I'll cause the tailing car to hit me. It's not as bad if there is a car in front of me. If no cars are in front of me, and...

Driving on 2 Lane Rd. Using Traffic Aware Cruise Control (TACC). 45-50 MPH. Vehicle will brake suddenly when a large vehicle cement truck, school bus approaches in opposite lane. It also happens when I am passing a bicyclist on my right side. It also happens intermittently but not as severely when there is nothing around me. This is a very dangerous situation because of the possibility of a rear end collision caused by the sudden braking. It is a reoccurring problem. I have not contacted Tesla as I assume that was a known problem. There was no advance warning of the braking.

What component or system failed or malfunctioned, and is it available for inspection upon request? Traffic Aware Cruise Control and Autopilot How was your safety or the safety of others put at risk? Yes. Has the problem been reproduced or confirmed by a dealer or independent service center? It has been confirmed by Tesla. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning lamps or lights. The issue appeared a couple of days after I took delivery of my Tesla Model Y. Please read for details below. This car is UNDRIVEABLE due to its Traffic Aware Cruise Control (TACC) System. Tesla does not provide a basic Cruise Control that just conforms to a set speed. A driver is left...

What component or system failed or malfunctioned, and is it available for inspection upon request? Answer: AutoPilot / TACC - over the first 800 miles I've used this car for, AutoPilot has not worked correctly in the day or night. There is a hesitation once every 5-10 miles. There is a forward collision warning without reason approximately every 20 miles, day or night. Upon request, the NHTSA may contact me and I will provide off-board videos of the claims within this complaint. How was your safety or the safety of others put at risk? Answer: There is a sudden braking for no apparent reason. There is a good possibility of being rear ended when behind a Vision only Tesla. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem has occurred multiple times over the 700 mile ownership of the car. Tesla’s remote service...

Driving on two-lane highway, speed limit 55mph, with Tesla traffic aware cruise control enabled. Multiple instances of the car automatically applying heavy braking when cresting a hill or when a large vehicle oncoming. These incidents occurred when there was no traffic immediately ahead in my traveled lane. Luckily there wasn't a vehicle following me closely or I could've been hit from behind.
