2021 Tesla Model 3 Speed Control & Cruise Problems

Incident Details: • Date of Incident: [XXX] • Time: [XXX] • Location: San antonio, Tx • Weather/Road Conditions: Clear, dry highway; 90 F • Speed: 60 mph; • Description: while driving my 2021 Tesla Model 3 with Full Self-Driving (FSD) software version 12.6.4 engaged, the vehicle unexpectedly changed lanes without my input, likely due to the Auto Lane Change feature. Immediately after, it braked hard for and unrecognized slowing traffic ahead. This sudden jolt caused immediate pain in my upper back, neck, and chest, which persists. I believe FSD misjudged traffic patterns or road conditions, a known issue with v12.6.4 based on online reports. The incident occurred in heavy traffic and no crash occurred, but the abrupt braking posed a safety risk and caused injury. I’m unable to see a doctor today but plan to soon for a diagnosis. This is a serious safety concern, as FSD’s erratic behavior could cause collisions or further injuries. Injuries: Yes, back, neck, and chest pain caused by sudden braking. No medical diagnosis yet; planning to see a doctor soon.

vehicle constantly phantom brakes while driving. i have reported 100+ incidents thru my tesla "report bug" feature. It will read the speed limit sign on the off ramp and slow the vehicle down 20mps abruptly, it will see a car on an onramp and slam the brakes on thinking there is a collision coming. it is every single day using cruise control

My Tesla was operating in Full-Self-Driving Beta when it experienced a sudden uncontrolled accelration event. I was driving on [XXX] at approximatley [XXX] this morning. The road speed limit was 40 mph. The car display was correctly showing that the road speed limit was 40mph. The speed offset in the cars setting was limited to 5 mph max above the speed limit. While the car was driving it suddenly accelerated very hard from approximately 40 mph to over 60mph before I was able to stab the brake pedal and kick the car out of full self driving mode. There were no errors, warnings, or signs that anything was wrong with the car. I have also notified Tesla via the service request function in the Tesla App under the section for "software performance".

The contact owns a 2021 Tesla Model 3. The contact stated while driving approximately 65 MPH, the braking system erroneously activated, causing the vehicle to abruptly decelerate. The contact stated that the failure was due to a failure with the computer reading the speed limit as 45 MPH instead of 65 MPH. The cause of the failure was not yet determined. The manufacturer and local dealer were not notified of the failure. The failure mileage was 35,000.

Ever since Tesla rolled out an update for everyone to beta test FSD, the adaptive cruise control has been changing speeds when near interstate type exits and entrances. I've had it change from 75 down to 40 mph which is dangerous in traffic. This change in speed some times is just a drop to the next 5mph increment, such as from 73 to 70. Sometimes it is more from 73 to 65 at the same place/exit. It is not consistent. The only thing consistent is it's near exits even when not in an exit lane or nearest lane to the exit. This "Feature" needs to be removed as it is unpredictable which makes it dangerous.

This car, like many Teslas, is experiencing what has been come to be known as phantom braking. When in the autopilot or full self driving, this car will occasionally to frequently, depending on the day, suddenly break where it will decelerate from say 65 mph to 45 or 50 in a very short period of time. This can happen in very busy traffic conditions. It seems to happen when I'm going faster rather than slower. For example, I haven't experienced it so much on City Street. It seems much more prominent on highways. This is an issue that has many YouTube videos about. It has been reported by many Tesla owners as well as the media.

Latest update changed the cruise control to force inclusion of autopilot. Cruise control function is now unavailable with without this autonomous feature. It's not only distracting, but aggravating. What's worse, is there's no online ability to inform or complain directly to Tesla. This isn't the first safety-related software glitch. Please get them to fix these issues.

While driving [XXX] on [XXX] in Texas, the Tesla autopilot abruptly and forcibly applied the brakes while I was driving approximately 77 mph. I was almost rear ended by a semi truck due to this issue. This happened again about 20 miles down the road and I disengaged the cruise control and autopilot altogether at that point. This is a continuous problem that needs to be addressed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owned a 2021 Tesla Model 3. The contact stated that after reversing out of a parking space, then shifting to the drive position and lightly pressing the accelerator pedal the vehicle suddenly experienced unintended acceleration and drove forward at a very high rate of speed. The vehicle drove across a street and crashed into a building. During the crash, the driver sustained an upper torso and neck injury and was transported to the hospital. One person inside the building was also injured during the incident. No further information was available. The vehicle was destroyed and towed away. A police report was taken at the scene. The manufacturer was notified of the incident. The failure mileage was 12,400.

The contact owns a 2021 Tesla Model 3. The contact stated that while attempting to park at 5 MPH, the brake pedal was depressed however the vehicle accelerated independently. As a result, the contact crashed into the two parked vehicles on the side of the parking space she was attempting to park. No air bags were deployed. One parked vehicle had an occupant and the other was unoccupied. There were no injuries or medical attention required. A police report was filed. The manufacturer was made aware of the failure and the vehicle was taken to an unknown dealer where it was unable to be diagnosed due to no available appointment. The dealer then suggested the vehicle be towed to the contact's residence where it currently remains in the garage. Tesla informed the contact that the brake system would not be inspected until she repaired the crash cosmetic damage to the vehicle. The approximate failure mileage was 33,000.

Driving on I-5 North from Los Angeles to San Francisco with adaptive cruise control activated. Suddenly and without warning car activates emergency braking as if it sees an obstruction on the road but obviously road was clear of any obstructions. This happened 4 times then I finally decided to no longer use cruise control. This happened on a clear sunny day around noon time 9/8/23.

This accident involved a high speed collision on the 2nd floor of a parking garage at a hospital in a suburb of Houston, Tx. Both the driver and the passenger were killed. A question has arisen as to how the vehicle could have accelerated at such a high rate, in such a short period of time, especially inside a parking garage? When we found out NHSTA was re-opening, the Tesla sudden acceleration issue, we thought it important to include the facts of our accident. Sudden acceleration in this case, raises some concern, taking into account the facts and circumstances surrounding this accident. We have photos of the vehicle if needed.

2021 Tesla Model 3 RWD; 21,000 miles I pulled into a parking spot creeping in like I am about to park the car. When I tapped on the break to stop the car, it suddenly accelerated forward. It jerked so quickly forward that the back of my head was pushed into the headrest like a whiplash. Luckily, there was not a car parked in front of me because I generally park away from other cars. I quickly hit the break and the car stopped. I am 100% positive I did not accidentally hit the gas pedal. If I did hit the gas petal, I would not have hit it hard enough to make the car jerk forward and accelerate like it did especially when in a slow creeping speed to come to a stop to park the car. In 36 yrs of driving I have not had one accident. This was quite a scary.

I was driving west bound on I4 August 12th 2023 at 1236pm at mile marker 45-47. I was in the left hand lane with the cruise control set at 73 mph. all traffic was moving well. there was no car in front of me. there was a car passing me slowly on the right. there was a retaining wall to my left. My car for no reason changed the setting on my cruise control from 73 to 35mph. this caused my husband and I to be thrown forward and I had to jam on the gas to try to regain speed. This was the 4th time this happened and the second time I have reported to Tesla who insists that there is nothing wrong with the car. I am scared if someone is following me closely I will be rear-ended at a high rate of speed. They continue to quote information from the manual and in the invoices insinuating that any incident occurring from this would be my fault. This is a terrifying thing to happen when there is no reason for the car to slow for any reason.

The vehicle was traveling in excess of 75 mph with only the autopilot system enabled. The vehicle brakes engaged by itself enough to squeal the tires and the rear end momentarily broke free from the pavement. I disengaged autopilot and drove for approximately 5 minutes. I reengaged autopilot and approximately 5 minutes later the brakes engaged again. I left autopilot disengaged for the remainder of the trip (~ 4 hrs) There were no other vehicles nearby but the breaking was severe enough that if another vehicle had been behind me, it could have caused a collision. The dealer acknowledges that this unintended breaking does occur on other vehicles. There was no warning that the vehicle would severely brake. The weather was clear with bright sun on route I25 south of Denver.

Just completed a 2week trip and the car attempted to stop on its own over 37 times (stopped counting) on the highway. 2times I had a semi within a block of my rear of the car. Since this occurrence is not anticipated it worries me that it's going to cause an accident. Reported to Tesla and it's days the feature is beta, I don't believe that for a second . This my 3td car with adaptive cruise control. I was not using the auto guidence feature.

Constant phantom breaking

When driving the Tesla model 3 in cruise control, It will without warning apply the brakes. I have to then accelerate and then take it out of cruise control. The issue has happened about a dozen times and only happens while in cruise control. It happened most recently today but has happened in previous days.

1:Brake fail when trying to stop the car after the accident. The car is available for inspection at Arrow towing service Oklahoma City. 2: After the car accident the car keep going can't stop got Tee boned and my passenger broke his legs and ankles, elbow. 3: No, the problem has not be discussed with the dealer or manufacturer yet. 4: No one, including police, insurance have been inspect it. 5: No warning lamp or any kind of warning.

The incident first happend (and has been happening ever since) on I-8, I-10, I-20 east bound 2 days ago. Driving on EB I-8 with speed limits 75MPH, engaged Tesla's well touted onboard Enhanced Auto Pilot (EAP) with Auto Steer control. There was no one ahead of us for over a mile. The weather was clear and sunny, time of incident around noon. Max speed was set to 75 on EAP. All of a sudden, we felt a jerky motion, and realized the EAP has activated brakes, dropping speed from set 75 to about 50mph. No visual or audible alarms, the EAP did not disengage. The driver took over to speed up to avoid being rear ended by vehicles coming behind us. It happened several times more during our trip and then we decided to manually drive. We have video documentation available.
