2023 Tesla Model 3 Complaint Log

Opening the car door of the Tesla, my fingernail got caught between the handle and the handle frame and was completely ripped off.

I am writing to file a claim regarding a safety issue with my Tesla vehicle, which is subject to the recall identified as NHTSA Recall Number 24V554. The recall involves a potential defect in the hood latch assembly, which may not detect an open condition. As a result, this defect can cause the front hood to unintentionally open while driving, potentially obstructing the driver’s view and increasing the risk of a collision. Safety Concerns: Although no crashes or injuries have been reported related to this issue, I experienced significant safety concerns while driving my vehicle. The possibility of the hood unexpectedly opening and obstructing my view caused considerable anxiety and distraction while operating the vehicle. Remedy and Actions Taken: Tesla has issued an over-the-air software update (firmware release 2024.20.3) to address this issue. However, despite the update, I remain concerned about the reliability of the latch system and the potential risk it poses to my safety and the safety of others on the road.

On 5/28/24, while pulling up the driveway, the car suddenly accelerated and it’s so fast that we couldn’t react. The car crashed into the garage, knocked down one wall along with the main electrical panel. It stopped because it got stuck on 10 in foundation’s of garage structure. The collision mitigation feature did not get triggered and didn’t give any alert or helped to stop the car from crashing into the garage. Airbags on both driver and passenger sides did not deploy. Prior to this accident, the car already had issue with the driver’s profiles and the seat just moved back and stuck at the easy entry mode. The car became inoperable because the driver’s seat can’t be moved forward to a position where I could reach the gas and brake pedal. I contacted Tesla service and was told to delete the driver’s profile and create new one , power off the screen, power cycled the car. I’ve done all of that but the problem kept happening on and off. The car was scheduled to be looked at by Tesla on 6-20-24 but the accident happened on 5-28-24. We’d like to find out the root cause of the accident whether the car has any malfunction that could’ve triggered the sudden unintended acceleration. We’ve reported the accident to both Tesla and my insurance company. Tesla confirmed that the data was downloaded and being reviewed and there is no available information to be shared with me at this time

The contact owns a 2023 Tesla Model 3. The contact stated while driving at various speeds with the Adaptive Cruise Control or ADAS Self Driving feature activated, the vehicle would independently decelerate without warning. During the failure, there were no other vehicles or objects nearby. The Service Center was notified of the failure through the Tesla App. The contact was informed that since a time stamp could not be provided for each failure, the Technician could not determine the cause of the failure. The manufacturer was not yet made aware of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 28,000.

I was turning onto a busy street and the car suddenly stopped and would not respond to the gas pedal. A message said "shift into drive". I had been driving for about a mile already and had not touched the shifter. I then tried to shift into drive and it would not change. I tried multiple times. I then opened the driver door, shut the door, pressed the break to put in my pin, and then it would shift into drive. This was very dangerous as it stopped with the car partially in the road. Luckily there were no cars around.

The contact owns a 2023 Tesla Model 3. The contact stated that while driving at an undisclosed speed in the rain with the windshield wipers activated, the windshield wipers became inoperable. The contact was able to turn the switch for the windshield wipers and the wiper blades started operating as needed. There were no warning lights illuminated. The local dealer was contacted, and the contact was informed that the contact was unable to determine the cause of the failure. The contact stated that the failure began after an OTA update. The vehicle was not diagnosed or repaired. The manufacturer was contacted. The approximate failure mileage was 11,800.

The contact owns a 2023 Tesla Model 3. The contact stated while driving approximately 72 MPH with the cruise control activated, the vehicle abruptly decelerated and nearly came to a complete stop. During the failure, there were no other vehicles or objects nearby. The cause of the failure was not yet determined. The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not yet contacted. The failure mileage was 6,730. The contact stated the primary concern is that unexpected emergency braking for no apparent reason on our 2023 Tesla Model 3 was dangerous. The dealer indicated that their review of the data for the approximate date and time did not show anything and cancelled the appointment.

The components that failed or malfunctioned include the braking system, steering system, and the airbag deployment mechanism. These critical systems experienced sudden and unexpected failures. Yes, the vehicle and its components are available for inspection upon request. -The sudden brake failure and steering wheel lock resulted in a complete loss of control over the vehicle. The inability to stop or steer the car properly led to it veering over the curb/grass area, posing a severe risk of collision. Additionally, the failure of the airbags to deploy during the impact further compromised my safety. This incident not only endangered my life but also posed a significant threat to the safety of other road users on Highway I676. -At this time, the problem has not been reproduced or confirmed by a dealer or independent service center. Further investigation and inspection are necessary to determine the root cause of these critical system failures. -There were no warning lamps, messages, or other symptoms indicating any issues with the braking system, steering system, or airbags prior to the sudden failure. The malfunction occurred without any prior warning, which exacerbates the concern regarding the vehicle’s safety systems.

Rattle sound in suspension and not sure if part is loose or bushing is worn out not even 1 year old car.

I was driving behind someone when a suv came over from left lane into the right lane in front of the cars that were in Front of me and made a sudden turn into a business. I was already applying the brake and was the 3 second rule behind the car in front of me, however the car did not stop as I slammed on the brakes as hard as I could. There have been other times that the car will automatically slammed brakes on because it feels that it need to…when it’s not necessary at all. But the other day when I needed the brakes to help me stop abruptly…they failed to do so. I hit the car in front of me and was cited as well. If I had been going faster..this could have been way worse. This definitely needs to be evaluated on Teslas. I have a dahcam video that I’m unable to upload.

When using cruise control, my 2023 Tesla Model 3 will aggressively brake without warning or apparent cause. The braking is near maximal - as though the vehicle is attempting to prevent an imminent collision. This defect poses a hazard to occupants of vehicles behind mine as well as myself and my passengers as sudden braking could cause a rear-end collision and cascading loss of control. Inclement weather would have exacerbated the problem. This problem is documented. From my brief research it appears Phantom Braking has been the subject of a NHTSA investigation previously but for prior model years. The issue persists. When I questioned Tesla Service regarding this life and limb threatening problem their staff was aware and well versed at requesting the customer report the issue as though it were a minor software glitch. This is a significantly more serious problem necessitating an appropriate response.

my model 3 is less than one year old, the both rear seatbelt buckles won’t latch

I was turning into a parking garage when my car suddenly slammed on the brakes very hard to a sudden stop. Like there was an imagined hazard. I did not have the car on auto Drive as I do not trust the technology, but Tesla had just offered everyone full self driving automation that month. I did not elect to use that, but I feel that technology had something to do with this. Not only the incident scary. The stop was so hard. I was in pain after.

when I was driving my Tesla Model 3 with FSD exiting [XXX] , the FSD directed me to a wrong routing. I corrected the direction by taking over the FSD, the car then lost its full braking system. I was not aware of it until my car slipped backward at a stop and hit a car behind me. The other driver is good enough to let me go, but my Tesla back bumper was damaged. When I got home and read the message on the screen, I was told that the braking hold was disabled, autopilot was disabled, braking charge was disabled, and wheel alignment was disabled, and more. I contacted Tesla and make an appointment half a month later. I was also told that the Tesla recommends to have alignment adjusted every 6000 miles or every 6 months- while I was not aware of this, I thought Tesla is maintenance free. This was what I told Tesla representative then: If this disfunction is safety related, it should be mandatory, not recommended! I feel I was lucky that I only have a small accident, it could be worse. I just dropped my car to Tesla for repair yesterday, the estimated costs was originally $275, then it went up to ~$1500, then ~$1800, When I was talking to a representative, the costs increased to $2167 in a few minutes! I asked why the prices go up, they said the previous prices are mistakes, and if I don't want to pay, I can drive my car home! I believe this happens to many other Tesla users as well, it needs to be addressed before more accidents and damages. The fragile safety operation and the way Tesla treat its customer are not acceptable, at least to my case. Thanks for your attention, if you need more information about my report, or have any question, please feel free to contact me.

Tesla Motors has two self-driving features, a mode they call enhanced autopilot and Full Self-Driving. Enhanced Autopilot is used primarily on freeways, and allows the car to switch lanes without driver's assistance, while maintaining the speed of traffic. Full Self Driving is a separate system in and of itself that relies on far more sensors, and is far more complex, as it needs to be in order to handle all the nuances of allowing a car to drive itself on and around city streets. During the month of April ,Tesla previewed the supposed improvements in its full self driving mode by releasing it to everyone for free for that month. I was exiting the 101 freeway in Los Angeles, utilizing the enhanced autopilot feature to navigate myself to my destination. At this exit, the car makes a right on Main St, drives downabout 500 feet and then makes another right so that you're briefly traveling underneath the freeway from you'd just exited. As the car made that second right, while on what should have full self-driving mode, the car failed to navigate the angle of that turn and ran right into a steep curb at a fairly fast speed, destroying the right drive train, the right tire, the entire front bumper, and the cars wheel chassis and suspsnesion system all still have to be fixed. I believe the malfunction was caused by the car failing to properly switch vbetween enhancd autopilot and full self-driving if they utilize GPS to mmake that determination, because it felt almost as if the car was trying to switch into the lane to the right (which didnt exist there was the curb there) and not like it was attempting to negotiate or preparing to make a wider turn maneuver. I don't believe it even decelerated as it hit the curb. I broke my toe but otherwise am all right. Tesla won't honor their warranty and is threatening to repo the car they won't fix.

Greetings, my name is --- My vehicle's VIN number is --- At the end of April 2024 I purchased a car from the seller, the seller claimed that my title was clean, he showed me pictures and it was indeed so When I came to Denver with this car, I put the car on the local registry and got a new title and it was clean too My wife was recently in an accident and the Tesla authorized service center didn't want to take the car in for service because the car has a salvage status in the title I started checking the car through several services that provide vehicle history, and found the following reports about it Source: [XXX] Date - [XXX] Type - Junk and Salvage Location - WESTCHESTER, IL Source: [XXX] Date - [XXX] Type - Total Loss Vehicle As we can see, this vehicle has 2 records of being Junk and Salvage and also a Total Loss vehicle But I was shown by the seller that the title is clean, also I was given a new title by the Arapahoe Motor Vehicle Services Office which is also clean. The official Tesla repair shops also refused to take my car for repair because they said that they do not support this title and that my car is salvaged. I would like to get the results of my car inspection from you if possible. I have also contacted the DMV of Texas and Colorado about this situation!

While the car was on the full self-driving it hit a metal block on the road. After the accident there was leakage behind the left front wheel of blue liquid and was suspected to be battery coolant. The car was not drivable due to safety concern. The car functions were degraded and air conditioning was not working. Sensors were on and off. The self-driving could not identify block and did not slow down. The self-driving system has major defect which is not safe to use at all.

The adaptive cruise control of the Tesla Model 3, like other Tesla models, rely on the cameras for determining speed. While driving on the freeway the Tesla Model 3 began to abruptly break almost causing a car to rear-end me. This has occurred multiple times since the full self driving was released to everyone. I discovered that the software reads the freeway's "Minimum Speed Limit" signs as the maximum speed limit. I reached out to Tesla and was told that there would be a firmware up-date but one has not come out since.

Design defect that caused the cooling system to fail and potentially not cooling the battery system. Per Tesla service center, leaves and debris which are common in everyday use got on top of the radiator, the fan on the back of the radiator sucked the debris and caused the damage to the radiator to leak. the radiator’s design may be inadequate, leading to the issue and caused potential damage to the battery pack or computer as a result of overheating which might leads to fatal accidents.

Using the Tesla "Autopark", the car backed right into a pole in back of the parking space. When the car hit the pole, it kept trying to back up rather than disengaging. It was a clear day, there was no traffic and there was no car in the adjacent parking space. This is using the latest version of Tesla's self-driving software, 12.3.3.

Automatic wipers are very erratic. Sometimes it works like crazy. Sometimes it never cleans the windshield even though it is soaking limiting visibility. Using it in manual mode is also very difficult as all adjustments are done on the screen forcing you to take your eyes off the road. There are no levers to adjust it.

Constant lane change while driving has gotten out of control. A couple of instance the vehicle has changed lanes without manual manipulation. This is getting out of hand and has certainly put risks on my family while operating vehicle.

The contact owns a 2023 Tesla Model 3. The contact received notification of NHTSA Campaign Number: 23V838000 (Electrical System) however, the instructions to do the recall repair were not accurate. While using the Tesla App, the Software version failed to display. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and confirmed that the instructions were not accurate to do the recall repair. The contact had not experienced a failure. VIN tool shows no open recall.

I am writing to express my frustration with the excessive nagging prompts I've been experiencing while using Tesla's Autopilot feature. While I appreciate the safety measures required by the NHTSA, the frequency and intrusiveness of the alerts have become disruptive and distracting, ultimately compromising the driving experience.The Autopilot system's constant reminders to keep my hands on the steering wheel, despite maintaining proper supervision, interrupts my focus and undermines the entire principle by forcing drivers to focus on the nag rather than the road. The frequency of these alerts feels excessive and unnecessary, especially on familiar routes where the system performs reliably. Requiring Tesla to nag the driver more often is an unreasonable measure that ultimately does little for driver attention.

The car phantom brakes constantly (at least every 10 miles) when using cruise control. You will be driving highway speed and the car will slam on the brakes for no reason,, making the cruise control dangerous and unusable

While driving in rain, the windshield wipers will randomly stop. This will happen both in AUTO and in MANUAL modes, especially at night in poor visibility. I contacted Tesla and they came and replaced the wiper motor assembly but the problem was not resolved. I believe it is a software issue. I nearly had a crash as this happened to me first at night in a very busy and complex highway intersection and resulted in me being stuck in the middle and blocking traffic until I could navigate the touch screen and find the wiper option to get it restarted.

When using FSD beta, vehicle would fail to stop for red lights. Vehicle also attempted to merge me both into a tractor trailer traveling the opposite direction and a jersey barrier. This is a very dangerous and unsafe system that will lead to many fatalities

Tesla autopilot drifted over two lanes and into the side of a semi-truck on the freeway. It was night time but with plenty of light, no rain, and clearly marked lines separating the lanes. Not only did autopilot fail, but the features to help avoid drifting out of a lane even when not using autopilot, also failed. Those features are supposed to auto-steer back into the lane and beep to alert the driver. None of this occurred. 1. Yes vehicle is available for inspection upon request 2. Could have easily led to extensive damage, injuries or fatalities. Everyone got lucky 3. Problem has not been reproduced by dealer, but I have video of the event 4. Vehicle has not been inspected by any 3rd parties

Driving normally down I-5, no other cars nearby and system suddenly phantom brakes. I am lucky no other cars were behind me as it may have well caused an accident. There were no other cars in front of me within at least 1 mile.

I have twice experienced a sudden acceleration when decreasing pressure on the accelerator pedal. It felt like the motor was producing full power. In both cases, I was able to quickly apply the brake which stopped the acceleration. Both episodes happened at slow speed, less than 20 mph, while either starting to slow for a stop or making a turn. Software on the car is fully up to date as of February 2024.

Unintended acceleration after I tried to park take off before I can parked it violently crash into the wall.

The contact owns a 2023 Tesla Model 3. The contact stated that while attempting to park the vehicle, the vehicle suddenly accelerated independently. The contact lost control of the vehicle, coming to a complete stop after crashing into two poles and veering into a brick wall, where the vehicle briefly continued to accelerate. The air bags did not deploy. A Police report was filed. There were no injuries were reported. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Action Number: DP23002 (Speed Control). The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 100,000.

Software updates caused failure notifications (seat restraint system) and disabled cameras/emergency brakes, happened immediately right after software updates. All hardware performed and properly functioned before the software updates. 1. First failure noticed on the begin of March 2024, component affected : " Rear center safety restraint system fault". Second failure noticed on [XXX] component affected: " Autopilot cameras unavailable", "Automatic emergency braking is unavailable" 2. I feel extremely unsafe now when using the vehicle with failure notification of the car's components, especially while driving my children to school. I am unsure if the system failure that could causes accidents and put my kids at risk or danger. 3. First issue was notified Tesla representative immediately right after the software update (happened over night). They scheduled an appointment, but I saw a charge bill that I have to approve before taking the car in for an inspection. It happened when my car is just out of warranty. I called Tesla dealership in Buena Park, CA to discuss about my safety concerns and got told it might be just a software glitch and I should be ok to drive. (??). Second issue was also notified Tesla and got a schedule for an inspection/service on December 10th, 2024, and again with an approval of $650 that I might got charged for ahead of the service ???? (Why do I get charged for something that wasn't my false until Tesla pushed a bad software to make us pay for their bad scripts?) 4. There was no failure notification "at all" before the last 2 or 3 software updates. Tesla offered some kind of 1 month free FSD then software updates to remove the FSD then everything started to fall apart. I am very concerned with Tesla software updates now and failures it might cause that put our family at risk because of their bad scripts or batches.

Unable to upgrade software. No yellow clock icon on my screen

My Auto Hold feature will intermittently malfunction. Although there's electronic (car's log) and I have pictures, Tesla service center is advising this is not a "serious" problem, I should pick up the car and re-create the error message and then return the car

Vehicle does not have the proper software updates needed to clear the two NHTSA recalls for my VIN.

The car has issue with suspension, i know it is sporty suspension, but I drove so many sport cars. But this is the only one that has jarring issue, my whole upper half is shaking back an forward on bumpy wavy roads causing me to have lower back pain and if i put my back head on head rest on these road my back head will be bouncing on it non stop. I went to service center and they say the car drive normally ,I told them mode 3 2024 does. Ot have that issue they say it is completely redesigned suspension. I told them from the sporty cars I drove non have that issue. They say model 3 is different than other models. It is so frustrating buying 2023 and having this issue and tesla is not will ing to fix it and have to suffer back pain .

The car went forward when in reverse mode. After going to other modes (drive/neutral/park) and back to reverse, the car kept going forward. Reset the system and the issue persisted. Finally resolved after third restart. The car bumped up against the driveway gate because it wouldn’t reverse despite the dashboard clearly indicating being in reverse. Contacted Tesla, who examined the system remotely and said no issue was identified. This was the second time this issue occurred, and Tesla offered no fix.

Wiper control is limited requiring the driver focus on the touch screen. Auto wipers activation is slow and does not keep windshield clear from rain, forcing the driver take the eyes off the road and find the small area on the touchscreen to control the various wipers speed.

The Autopilot feature of my Tesla Model 3 was safe and effective prior to the update mandated by NHTSA. With the recent update, I now receive multiple warnings during my drive on a daily basis for checking my mirrors or adjusting the radio. These are loud and startling. This update was completely unnecessary and counterproductive to my safety. I'm sure some Tesla drivers drive recklessly, but it makes just as much sense to require ICE vehicle manufacturers to install hardware/software to prevent drivers from doing donuts. Please reconsider the "recall" you mandated of Tesla. It was unhelpful. Respectfully, [XXX] Palmdale, CA INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving down the highway at less than 60 mph the rear drivers side window spontaneously exploded. There was no one next to me at the time. Nothing hit the window. It exploded and most of the glass blew out of the car onto the highway. I have video of the incident but can't upload that.

Ever since software release 2023.44.30, there has been a serious issue with automatic wipers and visibility during driving. It has been documented by drivers on the internet, however I simulated driving conditions in a car wash that has triggered auto wipers atleast a dozen times in the past. Today I recorded a 4 minute and 30 second video where there was zero activation of wipers at all with torrential rain simulated as well as soap fully covering the field of view. Since the auto wipers are tied to the autopilot and FSD system this could cause serious injury or death if not rectified.

I turned into a parking lot across a gutter filled with ice from a snow plow and drug a block of ice under the car about 50 feet. When I stopped there was a blue fluid leaking out from under the car. I had the car towed to a collision repair shop. Estimated cost to repair $21,591.79. Damage seems excessive for a low speed collision.

Driver seat will adjust itself while driving down the road. While the seat is moving by itself it will also roll the da window down and no way to roll it up. While all things happening the heat will also stop working.

On [XXX], around 1:00, I was driving normally on the highway. I remember using autopilot, and the speed limit was 55 mph, but I'm not very sure. At that time, it was raining heavily, and I was following the car in front, not doing anything else. Suddenly, I noticed that the Tesla car turned sharply to the left by itself! I couldn't control it. Let me repeat: the Tesla car suddenly turned left by itself. I instinctively grabbed the steering wheel, turned in the opposite direction to correct it, and pressed the brakes, but it was too late. I collided with a car in the adjacent lane, and the car later turned about 180 degrees and stopped! The left side airbags in the front and back all deployed! However, I were not injured. I got out of the car, immediately called the police, and contacted the owner of the collided vehicle. Later, the police arrived to document the incident. I believe it was a malfunction of the Tesla that caused the accident! I did not make a left turn manually! It was in normal driving mode. What component or system failed or malfunctioned, and is it available for inspection upon request? I have no idea, should check Tesla's driving records and the recorded video from the incident. Has the problem been reproduced or confirmed by a dealer or independent service center? No. 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? On the day of the accident, in the morning, I noticed that the car exhibited a slight phenomenon of accelerating and then stopping on its own while I was driving, It was first appear but it wasn't severe.

Car windshield cracked when the defrost run after snow fall. Car was parked in the driveway.

The contact owned a 2022 Tesla Model 3. The contact stated while driving at an undisclosed speed and merging right, the contact lost control of the vehicle and the vehicle stalled after crashing into the center median. The vehicle was totaled. No injuries were sustained. Medical attention was not sought. The contact stated that a Police report was not filed. The manufacturer was made aware of the failure. The failure mileage was 500.

1. My 90 year-old mother-in law got trapped inside the car in very bad weather because my phone key wouldn't open the door after I got out and walked her elderly friend to the door of her house about 20 feet away, and then walked back to the Tesla. I've been able to reproduce the problem repeatedly, of course without my mother-in-law in the car. 2. Several near-misses because, unlike most other cars, the Tesla's blind-spot warning system, and many other basic control functions such as adjusting the windshield wipers, opening the glove compartment, etc, require you to take your eyes off the road. For example changing lanes requires you to look away from the lane you're about to move into to check the blind spot display on the touch screen. 3. Several near misses because easing up on the accelerator slows down the car forcefully 98% of the time, but does nothing 2% of the time. Specifically, accidentally flicking down on the right-hand control stick, which turns on the windshield wipers in most cars, activates cruise control and gives minimal feedback to the driver that cruise control has indeed been activated. In this circumstance, easing up on the accelerator pedal doesn't slow down the car at all. This is very frightening and unexpected and could easily cause an accident.

When involved in a rear-end collision the drivers seat malfunctioned. It went into a laid down position and twisted causing a back injury.
