AUTOMATIC EMERGENCY BRAKING with Adaptive cruise control on. I was driving with adaptive cruise control on, at about 50 mph on a two lane road. the first experience I had was at dusk on a straight road when oncoming traffic with headlights seemed to trigger the braking system changing the speed of the car by about 10 mph repeatedly but not every car or truck. When I entered a curvy road section, it didn't trigger the brakes. The second experience was around noonish on a straight road, a large oncoming truck seemed to trigger the Automatic emergency braking and brought me suddenly to almost a stop from 50 mph. I looked behind me and saw no one close to rear ending me but it was scary to almost stop in the middle of my lane. no confirmation by dealer or service center, no inspection by others, no messages or other symptoms prior to the failure. No chimes or warning when it happened. The first experience appeared January 14, 2022 with approximately 350 miles on the new car. The second experience happened January 19th with approximately 450 miles on the car.
2022 Tesla Model Y driver assistance complaints
Page 19 of 19: complaints 521 to 531 of 531, newest first, as owners wrote them.
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.
2022 Tesla Model Y Long Range frequently experiences "phantom braking" and false emergency braking. Even without the use of "autopilot," the vehicle will abruptly slow down or even hard brake. No warnings, no messages, nothing. Each time, there is nothing in front of the vehicle, no curves, clear weather, etc. In another scenario, such as driving down a neighborhood street with curves, it thinks you are going to hit a parked car, and slams on the brakes as well. At least here you do get an alert indicating what the car was thinking. Even though it was clearly mistaken. Had it properly accounted for steering position, would have realized there was no danger. This is all extremely dangerous and is just asking for an accident due to being rear-ended. In addition, there have been many complaints about this on the forum for years, and even the latest software updates have not resolved.
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 with no option but to use their TACC or Autopilot both of which are utter garbage. Every couple or so miles my Model Y slows down in the best case scenario or slams the brakes for no apparent reason in the worst case scenario. My car has made me and my passengers sick because of this issue. Not to mention that at multiple occasions while driving on a highway my car has slammed the brakes when there was NOTHING in front of it, almost causing the car coming behind me to almost rear-end us. This is dangerous and stressful for my family and I and for people who drive behind my car. This is a massive safety issue which makes the car un-usable for long drives. Even the most basic car from the 1990s has a cruise control yet Tesla does not provide that option in their cars. So a person has to resort to using the TACC or Autopilot both of which are useless and dangerous because of this phantom braking issue. Please have Tesla provide a fix for this dangerous problem. This makes my car un-usable for long drives. Please help!!
I drive on a 2 lane undivided highway/road. When I have cruise control activated I have severe braking occurring when I drive past any larger truck/bus. It has almost caused me to be rear ended on more than one occasion.
The issue is with the standard self driving. When it is engaged while driving on the freeway it will randomly slams on the breaks. Very dangerous as someone could have rear ended me from behind. This occurs randomly and makes using this feature very dangerous!! I feel they should disengage the self driving until it gets fully tested.
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 federal safety agency 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 team insists that “These are known limitations of autopilot in some conditions”. “Reviewing my vehicle it is not reporting any faults, all cameras are reporting calibrated and the pitch angles are within speciation.” A test drive to confirm these settings was offered and accepted. The test drive confirmed Tesla’s opinion that the car was fine. The car has received three software OTA updates since I’ve received the car and I have catalogued similar issues with every update. After having Tesla inspect the car, they returned it to me without confirming any changes. Issues persist after inspection. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The manufacturer has inspected the car and found no faults. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lights, apart from Forward collision warnings that occurred at the time of use.
Passenger side b-pillar camera has condensation inside the glass and does not allow for it to opperate.
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.
While on cruise control the car brakes aggressively with oncoming traffic and when passing large vehicles on the highway. No way to disable this feature to use a standard cruise control. This seems to be a problem mostly with large vehicles on the road.
When using cruise control on normal two way traffic roads during the day or at night: the car will brake aggressively because of proper oncoming traffic from the other lane. The system has been very poorly designed such that it only works on wide separated highways and there is no way to switch off this feature. I have already had two near accidents where the vehicle behind me didn’t expect my car to slow down so quickly for no reason. This is extremely dangerous.
