| Sep 2023 | UNKNOWN OR OTHER | When I purchased this automobile the dealer told me it had to be built, so it was my thought I was getting a brand-new car. I was not anticipating the problems I would have in the same year I leased this vehicle. I leased the automobile for 3 years with an agreement to drive 12,000 miles or less a year. Later after agreeing to the mileage set in the original contract, I learned through my own research that I could leased this automobile agreeing to drive up to 20,000 miles. My contract was not explained or expressed to me in detail, even after conveying to them that the automobile would be used as a vehicle for my business in transportation. They did not go over every possible option. Secondly, just a few months into having this vehicle, I took the automobile in for service April 6, 2023 Feb 23, 2023 Jan 3, 2023 Nov 7 of 2022 and Oct 6 of 2022, for the same issue, breaks making noise in the reverse position and while driving. Each time I had to pay a service fee. I had one agent to convey to me that I needed a brand new break system because they were not able to fix the problem that was causing the vehicle to squeak. After researching this specific problem and talking to other Tesla owners, I have learned that this is a common issue with Tesla manufacturer. I believe that this was not due to neglect or error on my part. Before this recurring issue with both my Model 3, I was very pleased with my Tesla and in a few years I will need to upgrade to a larger one as I grow, but not I hesitate to choose one. A few of my clients and family members also one Tesla, that are functioning perfectly, and they aren't so sure that they will stick with the brand after watching my experiences. | Crash: No Fire: No | Unknown |
| Sep 2023 | STEERING | I was driving my car on the highway I275 approximatley 5 miles North of St Petersburg Florida. When without reason the car spun to the left very quickly, I did not have any steering control at that moment. If the car had hyro plained it would not have spun out of control so quickly. The road was slightly wet as there was a drizzle but not to any extent to allow the car to spin out of control due to heavy water. My vehicle hit the highway guard rail and was badly damaged. | Crash: Yes Fire: No Towed | Unknown |
| Sep 2023 | FORWARD COLLISION AVOIDANCE | Recently on a trip between Wichita Falls and Quanah Texas, my Tesla Model 3 while on autopilot repeatedly braked hard while traveling at 75 mph in moderate traffic. While this is a frequent occurrence with my model 3, this is the first time I felt at risk of an accident due to how hard the vehicle was breaking. | Crash: No Fire: No | Unknown |
| Sep 2023 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |
| Sep 2023 | VEHICLE SPEED CONTROL | 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. | Crash: Yes Fire: No Fatalities: 2 Towed Medical attention | Unknown |
| Sep 2023 | FORWARD COLLISION AVOIDANCE | While driving on a divided four lane interstate state highway, during daylight hours, sunny, clear, dry, minimal crosswind, the car spontaneously braked while under cruise control from approximately 75mph to 45mph. There was no oncoming traffic or mirages. Fortunately no following traffic either because they would have either struck us or run off the road. This happened three times in a very short period and we haven’t used it since. | Crash: No Fire: No | Unknown |
| Aug 2023 | FORWARD COLLISION AVOIDANCE | While the Traffic-Aware Cruise Control was engaged, my car abruptly tried to stop 8 times on the interstate while traveling at 80mph (the speed limit on the open stretch of road in central Utah). The weather was clear, no clouds, no wind, very light traffic, very good roads, no debris on the road, about 85 degrees, no shadows were cast on the road and during the day. I was on a 5 hour road trip. Out of the blue on at least 5 of the occasions, with a vehicle about a half mile or more ahead of me and no vehicle next to me my car abruptly braked - like emergency breaking - for no apparent reason. Two of the phantom braking occurrences happened when after passing a vehicle and I signaled and pulled back in to the right lane with at least a 3 second space, and my car emergency braked. This about caused an accident and thankfully it did not cause a road rage incident. Two of the times we were snacking once on vegetables when the car phantom braked and the bowl and vegetables went flying forward. Thankfully none of the times did I have my cup to my mouth as I would have gotten hot coffee on me and could have burned myself or have caused some destruction to my car. The passenger in my car safety was at great risk as well as everyone on the road near me. No warning that the car saw something or was going to emergency brake. My vehicle is available for inspection. I have not taken it to a dealer or elsewhere for replication nor has the vehicle or component(s) been inspected. There were never any warning lamps, messages or other symptoms of the problem prior to the failure. Also, the problem occurs 100% of the time I am at one particular place on a local freeway so it can be replicated. I do know that it will occur there so I plan for it. When I travel this road south bound there is never a problem but when I travel north bound 100% of the time my car will phantom brake regardless if it's day, night, clear or wet. Tesla needs another option for cruise control now! | Crash: No Fire: No | Unknown |
| Aug 2023 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Major phantom Braking at 70mph on interstate 5, 4 times the brakes slamed on as if yo had done an emergency stop from 70mph to 20mph fortunately we were not rear ended as I had my son and grandchildren in the car. The car was in cruise control on each occurrence I finally had to stop using it for fear of a major accident | Crash: No Fire: No | Unknown |
| Aug 2023 | FORWARD COLLISION AVOIDANCE | Intro: This is a well known problem with Tesla cars. It's referred to as "phantom braking" in the Facebook Tesla groups and is wide spread. Using only cameras since around 2021 for adaptive cruise control, the car will "slam on the brakes" even though the road is completely clear ahead. This can easily cause an accident if there is a car following you. It has occurred several times since I bought the car Jan 2022. - malfunction component adaptive cruise control. yes available for inspection - a rear end collision could occur when the car's brakes are activated so hard that the car decelerates from 70 to 20 in seconds - the problem is well documented - no, no inspection by any entity. Tesla knows the problems exists - no, no warning of any kind | Crash: No Fire: No | Unknown |
| Aug 2023 | STRUCTURE,UNKNOWN OR OTHER | Wide gap on left back side of trunk whenever it’s closed shut. Opens and close fine but it’s not properly closed. Water gets in through the gap and gets in the trunk whenever it rains or I go to the car wash | Crash: No Fire: No | Unknown |
| Aug 2023 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |
| Aug 2023 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | My Tesla Model 3 Phantom Brakes when using Cruise Control, particularly in the morning when the road is clear, no cars or obstacles in front or behind me. The NHTSA KNOWS THIS IS A PROBLEM AND I HAVE PREVIOUSLY MADE THIS COMPLAINT. I contacted Tesla to no avail. They did nothing. WHY HASN'T THE NHTSA DONE ANYTHING ABOUT THIS ISSUE. THIS IS DANGEROUS AS AN ACCIDENT IS WAITING TO HAPPEN. | Crash: No Fire: No | Unknown |
| Aug 2023 | VEHICLE SPEED CONTROL | 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. | Crash: No Fire: No | Unknown |
| Aug 2023 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | While the car was parked in a parking lot, I get two notification stating “Sentry mode has turned off due to a sentry system error.” When I checked out the car, the car has completely failed to do any of the computer related task, leaving only the gear, AC, and Bluetooth was working. None of the cameras, GPS, sensors, brightness mode and many others were completely stuck. This continued until the next day. This happened without prior symptoms or warnings. I would have been in deep trouble if I have been driving at the time of the incident. When I took the car to the shop, tesla didn’t update the status for a week. After a week, Tesla told us that the Turbo A, Autopilot main processor chip failed. This caused the autopilot to go on loop. Therefore the whole motherboard needed to be replaced. This happened to a brand new purchased Tesla 2021 standard range. Which cost me $2404.00. | Crash: No Fire: No | Unknown |
| Aug 2023 | VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |
| Aug 2023 | UNKNOWN OR OTHER | I am getting less miles than advertised on full charge. Six months ago I was getting 185 miles on full charge now I get 156. The vehicle has a little over 5k miles and 2021. FSD does not work as advertised, fails to turn and it makes sudden turns and stops | Crash: No Fire: No | Unknown |
| Aug 2023 | SEATS | The driver's seat automatically adjusts when I get into the car. Normally this is a good thing, right? But when my wife and I both get in the car, and I'm going to drive, the car often assumes my wife is the driver and adjusts the seats to her settings as I'm getting into the car. This is a serious problem that has the potential to injure me. Since I'm tall, and my wife is short, the seat starts moving forward as I get in, and it starts to crush me. It's too hard to get back out, and I'm not always able to select my seat configuration quickly enough. If I happen to be carrying something as I get into the car, then that object usually is compressed between me and the steering wheel. There have been times where I didn't have my legs in fully, and they started to get crushed by the seat pushing them forward into the steering wheel. I've talked to Tesla about this several times. Tesla employees have told me that they hear about this problem regularly, but they don't have a way to fix it. And when I ask how to contact Tesla, they tell me use Twitter. I think Tesla's service department should have a method to communicate customer complaints directly. No one has given me any feedback indicating that they intend to do anything, even though they acknowledge that this is dangerous. I also wonder if it is possible that this might happen while I'm driving! For example, what would happen if the battery on my phone drained? The bluetooth connection would be lost. Would the car then pair to my wife's phone and readjust the seats? Of course, there is a simple fix. Instead of doing the automatic but stupid and dangerous adjustment, it should just ask for my confirmation. And never automatically go into a mode of "let's crush the driver"! I only want a computer to think for me if it's going to reason properly, in every situation, every time. Clearly Tesla didn't think this one through. | Crash: No Fire: No | Unknown |
| Aug 2023 | STEERING | When performing a u-turn, at low speed, the steering wheel locked in position, only allowing the car to go straight. I was able to regain the ability to steer, after approximately 5 seconds. I didn't notice any alerts or warnings, as it was happening. It was in the middle of a busy intersection and I was fortunate I managed to regain control of the vehicle, in time. I have scheduled a service appointment with Tesla. the earliest available appointment is the 20th, in my area. I have since driven the vehicle, approximately 40 to 50 miles, without incident, but I am concerned that this might happen, again. | Crash: No Fire: No | Unknown |
| Aug 2023 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |
| Aug 2023 | FORWARD COLLISION AVOIDANCE | When cruise control is activated at highways speeds, vehicle sometimes brakes abruptly for no reason whatsoever. Issue is phantom braking. No other cars in sight, no changes in speed limits. Happened repeatedly on CA Hwy 46 between Interstate 5 and US 101 on 7/31/23 and 8/2/23. Similar instances observed on other highways, too. | Crash: No Fire: No | Unknown |
| Aug 2023 | FORWARD COLLISION AVOIDANCE | My 2021 Tesla Model 3 is having MORE occurrences of phantom braking than ever before when I drive with the Tesla Autopilot/Full Self Driving system activated. I paid extra for Full Self Drive (FSD) and engage it mostly on highway driving. A recent software update from Tesla pops up a message on my screen any time I DIS-engage the FSD asking me "What Happened?" and offers me the chance to record a 10-second voice message regarding why I turned off the FSD. Yesterday, on 07/31/2023 between 12pm PST and 2pm PST I must have made at least five such recordings, each time for phantom braking suddenly jerking my car slower while I drove on major highways. In each case I was on a 55 mph highway (or faster). In all the cases, my lane was wide open with NO cars even remotely close to me. Sometimes there was oncoming traffic in the approaching lane of traffic, but not always. It certainly should not be braking due to oncoming cars in THEIR CORRECT LANE. Yet the car slowed down suddenly over and over again. This is a repeated problem, but I haven't had so many instances in one long drive. Yesterday I got fed up and resorted to driving without Autopilot for a large portion of my 150 mile trip home. Sudden braking - for no reason - substantially increases the risk of getting rear-ended by the car behind and frankly causes near-panic with people in the car itself. | Crash: No Fire: No | Unknown |
| Jul 2023 | UNKNOWN OR OTHER | My car has a Homelink that will automatically open the garage door when approaching the door. Unfortunately, if the garage door is already open, this will unexpectedly close the door with no warning. This has resulted in damage to the trunk lid of another can that was parked in the garage with the trunk open. It is a dangerous situation for the door to close when others near the door are not warned or something in the path of the closing door. The Homelink does show the status of the door (open or closed) so it would be easy to not close the door if it was already open. When the Homelink is used to remotely close the door, it has a delay and will flash the lights before the door is closed to warn people who are in the way. This is an easy fix and I hope something can be done. Other Tesla owners have had the same problem. | Crash: No Fire: No | Unknown |
| Jul 2023 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | “Phantom Braking”. Driving on the interstate approximately 75 mph using cruise control, auto steer, not auto pilot. Within a span of three hours today we experienced at least six episodes of the car emergency braking for apparently no reason. Immediately going from 75 to 40 mph. Thankfully no one was close behind us. We finally stopped using the cruise control. Now afraid to use it at all. | Crash: No Fire: No | Unknown |
| Jul 2023 | FORWARD COLLISION AVOIDANCE | The contact owns a 2021 Tesla Model 3. The contact stated while using a self-driving mode at 50 mph, it would not stay in the lane and drive slowly into the next lane. The contact stated on April 9, 2023, while using a self-driving mode at 15 mph, a pedestrian walked into the lane and the vehicle did not detect the person and hit the pedestrian. No air bags deployed. The contact did not sustain any injuries. The pedestrian sustained an unknown fractured leg and a fractured arm and sought medical attention for his injuries. A police report was filed. The vehicle was not drivable. The vehicle was towed to a Tesla collision shop and had the front windshield replaced. The contact took the vehicle to the local dealer but was informed no failure was detected. The vehicle was not repaired and continued to experience the failure. The manufacturer had been informed of the failure. The failure mileage was 48,570. | Crash: Yes Fire: No Injuries: 1 Towed Medical attention | 48,570 |
| Jul 2023 | UNKNOWN OR OTHER | This is a report of the accident I was in on July 15, 2023 at 3:00 PM. I was going south on two lane Hwy 160 a couple south miles of Hwy 12 when I pulled out onto a wide, long pullout. When I decided to get back on the highway, I looked back to see a long line of cars coming. My Tesla’s Full Self Driving has Auto Lane Change which switches lanes for you when safe. I figured I would use Auto Lane Change to merge onto the road when safe. I already had the Tesla Navigation on. I turned on the Full Self Drive and my blinker, thinking that it would be a while before the Tesla decided it was safe to merge onto the road. However, the car started moving toward the road almost immediately. I realized that there couldn’t have been a break in traffic already. I turned in disbelief. Just then the left side of the was smashed. I looked ahead to see a SUV swerving back and forth down the road trying to regain control. Then the blur of another car. The SUV was sailing through the air, then it was sliding on its roof. I rushed to the SUV feeling like there was a good chance that people were really hurt or dead. I couldn’t see inside because of the airbags.The driver’s door wouldn’t open. I rushed around the back of the car and saw a dog getting out of the front passenger door followed by a man. The man helped his wife out. Thankfully, they were not hurt. While waiting for the tow truck, one of the fishermen who were hanging around for some reason asked me for my ID. I asked why. He said his car was in the accident and pointed across the highway to over a 15 foot embankment and to about 500 hundred yards away where I saw his car. He said that his car had been parked and was hit by the SUV. With the stress and adrenaline of the accident and because there was only my car and the SUV on the side of the road, I realized that this was the car I had seen in a blur during the whirlwind accident. | Crash: Yes Fire: No Towed | Unknown |
