Unexpected phantom braking was experienced in this vehicle on a sunny day at mid day on I-30 going east through arlington. The car was operating on traffic aware cruise control. Travelling at approx 70mph the vehicle suddenly slowed very quickly below 50 mph before I interceded to resume control of the accelerator to resume my speed before I was rear ended. This occured as I was approaching an overpass in my middle lane.
Cars computer froze and I was stuck in cruise control. Hitting the brake would not disengage. Pressing up on the stalk would not disengage. I could manually slow/accelerate the car with the brake/accelerator but after letting off the car would continue on at that speed while everything else remains frozen. No turning signal function. I was afraid to attempt to stop the car fully as it would not disengage. Screen eventually went black and reset after what felt like forever. Functions returned to normal.
The car exceeds the speed limit with adaptive cruise control/autopilot, despite all the available settings being set to strictly obey the speed limit. Driving on the highway in a 60mph zone enabling autopilot will set the speed to 60mph, as expected. If the speed limit increases, the car will change to the new speed limit, e. G. 70mph. Now, if the speed limit drops back down to 60, the car will not slow to 60, although the correct speed limit is displayed. Also happens on streets.
The emergency automatic brake, cruise control and auto pilot feature gets disabled frequently. All 3 features gets disabled at same time. Contacted Tesla service center in decatur-GA. They are saying they cannot find the problem and hence cannot solve it. They say the engineers are looking into it, and my car needs a firmware update. No estimated time to fix these issues is given. The service center advised that the car is safe to drive! please help. Thanks.
Vehicle was at a stop with brake engaged and then it proceeded to go full speed into a vehicle two meters away without acceleration pedal engaged. Emergency brake did not activate during or slightly before the collision. The brakes had to be engaged manually, but vehicle was already past a certain velocity on its own accord to be able to stop properly without damaging property or harming pedestrians.
My Tesla Model 3 is equipped with standard auto pilot (no full-self driving) and traffic aware cruise control (tacc or otherwise known as adaptive cruise control). While engaged, I experience, on average, per 60-mile trip a minimum of 1 phantom braking event. Note this is not on residential, county or state roads, this is on divided highways. The vehicle will slam on the brakes for no reason and will at times activate the forward collision warning system. It's so bad I've disabled many of the safety systems for fear I will cause an accident. Traffic aware cruise control on a two lane road (this does not steer or lane center the vehicle), is unusable because it constantly brakes for oncoming traffic in other lanes, or aggressively brakes for vehicles turning in front of you, even with plenty of distance to clear. The system will even continue to brake, after the turning vehicle has fully cleared the road. This requires the driver to slam the accelerator to cancel the braking action. When I first purchased the vehicle in February of 2020, there were no issues with phantom braking. This issue has become worse with over-the-air updates. I canceled my full-self driving subscription because the phantom braking was even worse with that software. Additionally, Tesla uses a driver safety score to determine insurance rates if you are using their branded insurance program. When these phantom braking events occur it sometimes registers as an emergency braking event which deducts from your overall score and can ultimately cause your rates to increase. When I enrolled in fsd, before Tesla would release the software, they required a certain safety score over a week's time. During that time the system falsely reported running red lights, emergency braking events, and aggressive stopping, while only using the regenerative braking system. They system will also flag you for tailgating with auto pilot engaged.
Phantom braking can occur when vehicles are passing at night and during the day for no reason. There is no adequate control to enable the windshield wipers. Many menus to access the wiper controls. Not safe.
There is a complete failure of the autopilot (cruise control) feature and sudden braking when using. There is an extreme risk to personal safety when using this feature. On several occasions, I have been using this feature on the highway while going the posted speed limit of 65 or 70 mph. Suddenly, the vehicle will decelerate aggressively and violently causing any vehicles behind me to slam on their brakes to avoid a collision. This feature of the vehicle is not recognizing road signs, or other inanimate objects, correctly and mistakes them for some hazard that requires braking. Very dangerous.
On Tuesday 2/1/2022 approximately 9:20am est, as I was sitting in a stop-and-go traffic, as the traffic was freeing up and started moving going roughly 5 to 10 mph, the vehicle automatically applied phantom brake - with a notification of emergency braking applied. I was not on cruse control or autopilot. I was in full control of the car yet it suddenly applied the ebrakes nearly causing someone to rear end me since the traffic had started moving.
Using either cruise control or full self driving mode, driving on divided highway, experienced sudden hard braking not due to any highway obstruction, road hazard, other vehicle, or weather. Without warning car dropped out of assisted control and abruptly applied brakes. This happened yesterday at 2:10 pm, 2:53 pm and 3:01 pm.
The contact owned a 2020 Tesla Model 3. The contact stated while driving 25 mph, the vehicle accelerated independently and jumped forward and hit another driver that was standing outside in between the driver's side front and rear door. The hood opened and obstructed his view which caused him to crash into another vehicle. There was no injuries sustained by the contact. The two other drivers sustained unknown injuries. One driver received medical attention and was transported by ambulance. A police report was filed. The vehicle was towed to a body shop and deemed to be a total loss. The vehicle was currently at the contact's place of business. The manufacturer was not made aware of the failure. The failure mileage was 2,500.
The contact stated that while idling and waiting to pick up the elementary school kids in their vehicle, a 2020 Tesla Model 3 suddenly experienced unintended acceleration causing the driver to lose control of the vehicle and crash into the rear of the contact's vehicle and trailer. During the incident, the contact sustained a lower back injury and the driver of the Tesla Model 3 suffered a chest injury. A police report was taken at the scene. No further information was available. The failure mileage was unknown.
We had Model 3 with instance of unintended acceleration at the gate of a parking lot. This car was bought in may 2020. On December 6, 2020, she was on the way out of the parking gate and suddenly the car accelerated, hitting the side wall of the gate. The car flew over a two-way street, resulting in a compound fracture of her right hip requiring internal fixation and transfusion. The vehicle was inspected by the police. There were no warning lamps, messages, or other symptoms prior to failure.
Just purchase the auto pilot, when coming to a stop, sometime it pass the white line. While going stright,when signal to change lane to bypass the slow car, it merge into left turn at the stop light. When the vheicle is going around a left corner, it veer to the right and drove on the should lane. The same thing happen going to the right corner. When take off from the green light, sometime it slowly,slowly,slowly increase speed even though there is no car in front of it. When slow down, it wait the last minute and turn the car. All my stuff on the seat fly every where . When approaching a corner, it would speed up and make a quick turn. . When using a navigation, it turn intoi a dead end instead of the right route.
Slowed down to make a left turn and the car suddenly speed forward when I put my foot on the brake. I let go my foot and slammed the brake once more. It took a second to respond.
The contact owns a 2020 Tesla Model 3. The contact stated that while his wife coming to a stop sign, the vehicle accelerated independently without warning and crashed into the rear of a pickup truck. The air bags failed to deploy. A police report was filed. There was no injury information provided. The vehicle was towed to independent mechanic but not diagnosed. The contact mentioned that Tesla performed a diagnostic testing remotely but refuses to inform the contact of the results. The manufacturer was notified of the failure and informed the contact that after an internal investigation the contact would receive a callback. The failure mileage was unknown.
While navigating on autopilot on the freeway the car took the intended exit ramp, however never slowed down until I had to intervene. Reminiscent of the characteristics which led to the recent fatal crash reported over the last week.
