2023 TESLA MODEL 3 Service Brakes Problems

Regen braking sporadically not working when going down mountain or steep roads. Sometimes they work and sometimes they won’t. This is after extensive driving on warm days while battery is between 70-80%. Support could not help me and they don’t have any technicians available. I’ve sent them videos and time stamps and they are ignoring the issue and unable to help due to lack of knowledgable representatives This is a serious safety concern

The vehicle’s brakes did not work, automatic emergency brakes and collision warning both did not work. I pressed on the brake for about 5 seconds but the brakes did not work, resulting in a collision with the car in front. Everything is available for inspection if needed. Both my safety and the driver of the vehicle in front of me was at risk. The problem has not been confirmed yet. The vehicle is currently at a shop, waiting inspection. There were no warning lamps, messages, or symptoms.

On [XXX], my 2023 Tesla Model 3 (VIN: [XXX] ) suddenly accelerated on its own and the brakes failed to respond despite repeated pressing. To avoid hitting other vehicles, I turned into a property driveway and struck a tree. The airbags deployed. This was a case of sudden unintended acceleration combined with complete brake failure, creating a serious safety hazard. Forward Collision Warning also did not prevent the impact. A police report was filed by the Dekalb County Police Department, GA, USA (Report #[XXX], Case #[XXX]), which specifically documented brake failure as the cause of the accident. The report also notes that the driver was injured by the airbag and that the vehicle had to be towed from the scene. A copy of the police report can be provided upon request.

Three times while driving at low speed and attempting to reduce speed—even while pressing the brake pedal—my 2023 Tesla Model 3 unexpectedly accelerated. During the first incident, the Dynamics screen did not allow me to change the Deceleration Mode. After rebooting the touchscreen, the options reappeared briefly, but later that same day they became unavailable again. Incident Times: 2nd incident: September 3, 2025, at approximately 4:15 PM EST 3rd incident: September 4, 2025, at approximately 4:50 PM EST

While driving to work on a local road, I approached a red light where there were no vehicles immediately ahead. However, my vehicle unexpectedly steered off the road in front of a construction sign, entering a ditch. Despite my attempts to regain control of the steering and braking systems, I was unsuccessful. The vehicle subsequently stopped automatically on an incline. Fortunately, I avoided a collision with a gas station and intersecting roadway, but sustained damage to my car’s front bumper. Law enforcement and a towing service were contacted to remove the vehicle. I tried calling the dealership almost half day without an answer, then I went to the dealership where they told me that the hardware is fine but they can’t do anything about the possible software issues which leaves me in a situation where I’m nervous to drive the car. I reached out to the company about the accident and didn’t hear back yet from them. I request a thorough investigation into this incident to determine the cause of the unexpected, highly dangerous, autopilot behavior. I am disturbed mentally and emotionally due to the accident. I also require confirmation of the vehicle's roadworthiness and assurance that it is safe to operate before resuming driving.

The contact rented a 2023 Tesla Model 3. The contact stated that while driving at 55 MPH in the rain, a vehicle in front of him abruptly slowed down. The contact depressed the brake pedal, but the vehicle jerked to the side. The contact stated that the emergency braking system unexpectedly activated ("slams on") while he was driving due to the Automatic Emergency Braking (AEB) system falsely detecting a potential collision. There were large rocks in the roadway, and there was no traction, causing him to crash into an embankment. The driver's side airbag did not deploy. The other airbags in the vehicle had deployed. The contact sustained a fractured rib, and medical attention was provided at the hospital. The vehicle was towed to a towing company. There were no reported fires. A police report was filed. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic, where an unknown diagnosis was completed. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was unknown.

My dad was driving to work in the morning in the Tesla in the left lane of the freeway. Then the car started swerving on its own. He tried to regain control with the steering wheel but he couldn’t control it. The car wouldn’t turn when using the steering wheel and he was not using autopilot or lane assistance. He said it felt like the steering wheel and the car were not talking to each other. And the brakes weren’t stopping the car at all and because he couldn’t control the car it turned left into the divider and hit the divider and the car turn again to the right and automatically stopped in the middle of the second lane. The airbags deployed for the driver side. Thankfully there weren’t any other cars on the road at the time so there aren’t any injuries. But this crash could’ve caused serious injuries to him or other people. There were no warning signs, alerts, or noises before this happened. He has filed a claim with the insurance company. And a crash report was filed by the police.

I was involved in an accident due to what I believe was a malfunction in my Tesla’s steering system. While driving, the car unexpectedly turned the wheel to the left on its own and collided with a parked car. Despite my efforts to regain control by turning the wheel to the right and applying the brakes, the vehicle did not respond, and I was unable to prevent the crash. Given the lack of control and failure of the braking system, I strongly believe there was a serious issue with the car that led to the accident.

during a hydroplaning incident on a ramp, the tesla refused to budge or give any steer. Major issue was no air bags deployed during collision.

Brake Feature Malfunction Vehicle Details: •Model: Tesla Model 3 •Year: 2023 (approximately 1 year old) •Mileage at Incident: ~11,000 miles Incident Description: On 10/29, while manually driving my Tesla Model 3 on a public roadway, I experienced a critical braking failure. As I approached a vehicle in front of me that was decelerating, I initiated regenerative braking, then immediately applied the brake pedal forcefully. Despite pressing the brake pedal hard multiple times, the vehicle did not decelerate as expected and ultimately collided with the vehicle ahead. Throughout this incident, no collision warning, automatic braking, or other safety features activated, despite having all safety features enabled. This failure significantly impacted my confidence in the vehicle’s braking and safety systems. After the accident, I reviewed the Tesla incident report, which shows I attempted to brake but that acceleration was not reduced until the collision occurred. Despite the report documenting my attempts to brake, the system did not function properly, suggesting a potential mechanical or software defect in the braking and/or safety alert systems. Aftermath: •My vehicle sustained considerable damage. •I now feel unsafe driving the vehicle, particularly on highways, as I am concerned the brake failure could recur. Request for Investigation: Given the severity of this issue, I am seeking an investigation to determine: 1.Whether there is a defect in Tesla Model 3 braking systems that could result in brake failure under normal driving conditions. 2.If there is an issue with the vehicle’s safety features failing to activate appropriately. This incident has raised significant concerns regarding my safety and that of other drivers, especially given the car’s relatively new condition and low mileage. I would appreciate a prompt investigation into these safety concerns.

With the TACC system activated when traveling on a 2-lane road with a right-hand curve, if there is a semi-truck in the opposing lane, the emergency braking engages with a hard brake application. It can be overridden with accelerator pedal, but it endangers the car from collision with a following vehicle. There have been multiple incidents. I attempted to report the condition to Tesla customer support.

The contact owns a 2023 Tesla Model 3. The contact stated that while entering a parking lot, the brake pedal failed to respond, the driver was unable to control the steering wheel and crashed into a Ford vehicle and a tree. The air bags deployed, and the vehicle stopped shortly after. The forward collision emergency braking system failed to engage. There were no warning lights illuminated. The vehicle was towed to a tow lot. A police report was filed. There was no reported fire. The contact sustained injuries to the neck and shoulder and had bruises. Medical attention was provided. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 12,166.

Mileage: 12,166

This is a duplicate of the letter I sent to Tesla on June 25, 2024. “For the past two weeks I have traveled to New Jersey and back to North Carolina. I’m writing to you because of my experience with TESLAS FSD. On one occasion I was traveling on [XXX] (NJ) heading to [XXX] -with my navigation and FSD engaged, I approached north and south exit ramps, my Tesla could not make a decision - I had to bring my car to a full stop before the apex of the exit. Cars wizzing by me on both sides. On [XXX] heading home on [XXX] somewhere in Virginia- with NO ONE around me doing about 65 mph, my car almost came to an abrupt stop ON THE HIGHWAY - once again, FSD FULLY ENGAGED - MY FOOT OFF THE BRAKE AND MY HANDS LIGHTLY ON THE STEERING WHEEL. WHY? I have NO CLUE - fortunately it reversed itself back into normal. Of course, both of the above incidents frightened me. I’m writing to you because I want a record of these events. I know my software is up to date and I’m not quite sure what to do about this.

Vehicle was in cruise control, and cruise control did not deactivate causing the vehicle to propel into a building, causing airbag deployment. Safety sensors of car failed to recognize building, other vehicles, and obstructions as required.

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.

On [XXX], I was driving my Tesla model 3 from California to my new home in Idaho as part of my move there. During the day, I had 6 or 7 situations where the car would suddenly go into full regenerative braking, or outright apply the brakes for no apparent reason. Most of these events took place of freeways at freeways speeds, or on highways (not freeways) at the local speed limit. Every situation was when I had supervised self drive or traffic aware cruise control enabled. These situations were extremely startling and in my opinion potentially dangerous. I don't want to imagine what might have happened if one of these "phantom braking" events had occurred with a heavy 18 wheeler behind me in traffic.

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.

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.

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

This incident is reported by a law office. The car being driven by our client was a TESLA Model 3 which made a SUDDEN UNEXPECTED ACCELERATION when our client was slowly looking for a parking space at a parking lot. The TESLA car suddenly accelerated at a high rate of speed without client pressing on the accelerator. On the contrary, our client was stepping on the brakes in an attempt to stop it but the TESLA did not stop but still continued to accelerate. This accident caused property damages and injuries to our client, his passenger, and others.

As I was approaching my off ramp (which has a very tight turn), my automatic brakes failed which caused me to slam onto the brakes, and skid into one of the off ramp signs. All 3 of my children were in the back, the back driver side window shattered, I lost my driver side mirror, and there was damage done to the back door and wheel well (all on the driver's side). Although the damage looked minimal, no one was willing to work on the vehicle and I was strongly encouraged by my insurance company to claim it as a total loss. Granted, I had this vehicle for approximately 2 months, and had put at least $4,000 into it.

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

Autosteer was engaged while approaching Weatherford, OK on I40 - Sporadically, the vehicle slammed on the brakes, even though nothing was in front of me, and nothing was behind. The vehicle dropped in speed by almost 20 mph.

Bought a 2023 Tesla model 3 performance that vibrates from the day I bought it. After 12 service visits, new wheels tires and even a new brake rotor the car is still vibrating. Tesla seems to say it’s normal and that all teslas drive like this but no other vehicle manufacturer has ever produced a car that vibrates. It’s unsafe and scary to drive this car the way it is. They tried fixing it at first hence why so many parts got replaced but since they don’t know how to fix it they wanna just push the “it’s normal and within spec” speech to me. Please get a recall going to address the ongoing steering wheel vibration problem faced by numerous owners as shown on numerous threads and forums. This is unacceptable.

On 2 separate occasions, the cruise control set to 80 and suddenly decelerates. Very scary. Term being used in Tesla chat rooms is 'phantom breaking'.

While driving with cruse controll, auto pilot, or adaptive cruise control my vehicle brakes suddenly without warning and without any reason or danger. This has happened many times. Today on the I8 traveling from Yuma az to Surpirse AZ the car braked around 15-20 times with out reason. I held the tesla car symbol on the screen to report the problem.

When cruise control is engaged, the vehicle suddenly decelerates, (at times dropping speed by more than 20 mph in less than 2 seconds). This occurs as often as 5-10 times in a single 60mi trip, and occurs at least once per trip on this same route (divided highway, sometimes with hills, often with no other cars ahead of or around the vehicle, speed 60-70mph) These events are unsafe because unexpected braking is a hazard for following cars and my passengers. My job as a driver is to be as predictable as possible, but when I use the cruise control the car behaves unpredictability Problem reported to dealer, confirmed by remote diagnostic, and car was serviced but the problem got worse. There are no warning lamps or error messages displayed in conjunction with these sudden braking events. First appeared when the car reached 2000miles on odometer

When on a recent trip from Salt Lake City to Denver Via I 15 to hwy 6 and on I 70 When it was in cruse control and also auto pilot the car would on it's own brake. Some of the time it would brake very harshly others it would not be so violet ,but would certainly be some thing that could cause a very bad accident. The only solution Tesla service would offer was to go on a test drive to see it happen. This could take posably many miles, and then said they did not have a solution.

I was driving on I-35 from Kansas City to Des Moines on 9-11-23, and three times the car experienced phantom braking (i.e. the car suddenly braked for no apparent reason) while the adaptive cruise control was activated. During these instances the car would suddenly brake and slow down and on one occasion I had to accelerate immediately to avoid possibly being rear ended. On all occasions there were no obstacles on the road or cars within 1/4 of a mile ahead of me.

On 09/11/2023 at approx. 6AM CST, my wife went to a nearby Walmart store for groceries. As she was parking the car in the parking space, the car started to accelerate by itself and went around the parking lot in random directions. She couldn't control the steering and brake despite the continuous tries. It was such a traumatic experience, and the car went on to hit couple of other parked cars and the cart return stations in the parking lot. After few seconds of random self-drive in multiple directions of parking lot, it finally came to a halt as it got on a curb that flattened the tires. By God's grace, the car stopped right before entering the main busy road due to flat tires and also no pedestrians at that time. Otherwise, the situation could have been worse as the car was going in an uncontrollable manner. The incident was reported to 911 and they got the car towed to a towing garage. We got the incident report from the police department. They also have the CCTV footage of this incident. We also have the dashcam videos recorded by TESLA and pictures taken after the incident. I will provide any supporting documentation you might need to understand this incident and address the issue. We are trying to come out of the trauma from this incident and would like to bring this issue to the attention of all concerned parties for next steps.

I was coming to a stop due to a train passing by. As I got closer to the other vehicles that were waiting for the train, I let go of the acceleration and then the vehicle on its own launched forward rear ending the car in front of me.

While using cruise control on a highway traveling between 65 and 75 MPH the brakes slammed on when there was absolutely no traffic in front of or beside us, no overhead obstructions, no upcoming corners, nothing at all but straight road ahead. If anyone had been behind us we could easily have been rear-ended. The car had only 1500 miles on it the first time it happened. There were 4 such events in our short 400 mile road trip. Took it directly to Tesla service and have been told there is nothing wrong with the car!

The contact owns a 2023 Tesla Model 3. The contact stated that while driving at an undisclosed speed with the cruise control activated, the vehicle experienced phantom braking. The contact stated that there were no objects or other vehicles nearby when the failure occurred. The vehicle seemed to return to normal functionality, but the failure recurred a second time. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 7,200.

Mileage: 7,200

Emergency braking applied when no other vehicles were in sight. Braking was hard enough to spill coffee. Seems to occur when adaptive cruise control is on. Happened about 10 times on recent road trip. Lucky no one was behind us! Felt very unsafe.

I was stopped before turning left into a parking space. I was driving slowly. The car stopped but I did not engage the brake as a Tesla will stop once the foot is removed from the accelerator. At that point the car leaped forward at full speed hitting parts of a building and a fence. I did NOT step on the accelerator. No one was injured. The airbags did not deploy even though there was $17,000 damage to the front of the car. There were no warning signals. The person inside the building was waiting for me and saw the car come to a stop.

on July 18th around, 7:00PM, the location is 1688 Hostetter Road Pacific, Rim Lane, San Jose, CA 95131. when I parked my car, and the car almost stop, the car suddenly unintended accelerated and hit another car. the car I used Creep mode, not Hold mode. I definitely sure my foot on the break.

While I was driving along a freeway using autopilot cruise control, the car suddenly slammed its brakes even if there was no cars in front of us. I thought it was just a fluke but it happened at least twice if not thrice during that trip. There was at least an approximate of 3 miles gap between us and the car in front, so practically no cars in front. Had there any vehicles behind us, it would for sure rear ended us.

I have had this car for 6 months. Three times within the past month sudden braking (phantom braking) occurred while driving on the high way with cruise control engaged. The car slowed from 70miles/hour to 35-40 miles/hour without warning on a clear day on a clear road. Then the car picked up speed. The cars in the front and the rear were far away to cause any incident. This happens in a random fashion and cannot be reproduced.

We have experienced several episodes of the car suddenly breaking for no reason when using cruise control. The speed is very quickly reduced a good 15 mph without warning.this is not only very alarming as drivers/passengers but it is incredibly dangerous. If there was a car following closely behind us, they would have hit us.

While in cruise control vehicle will brake hard as if it detects something in front but there’s really a clear road.

On several occasions ( 8 or 10 times) while driving at highway speeds, with little traffic, on an extended trip, the vehicle suddenly applied the brakes for no apparent reason. I have learned that this is called "phantom braking". On one such occasion, I narrowly avoided being struck from behind by another vehicle following me by applying the accelerator. I have not yet reported this problem to Tesla, but intend to.

While in cruise control, the car suddenly reduced its speed; there is no obstacle in the path of the cat that would warrant such an action. This deceleration is sudden and violent and when it happens is dangerous for following drivers.

Phantom braking. Traveling highway 5 Southbound between Red Bluff, CA and WIliams, CA at 70 mph, the vehicle suddenly and firmly applied brakes as if attempting to avoid a collision with an obstacle closely ahead. The braking force was enough to activate the seatbelt restraint. There was no traffic for at least a 1/4 mile ahead and behind and no obstacle. I managed to flip the ACC lever up to disable it during the braking but felt that I was losing control of the vehicle. After ACC was disabled normal operation ensued. Speculation: The incident occurred mid-May and the area is agricultural and therefore teeming with bugs that collect on the front of the car. The forward camera may have been hit by a bug and the visual recognition system may have mistaken the bug for a large obstacle.

Hello, I have experienced 2 times the same issue with this new car model. I was driving on a interstate with 2 lanes, no cars in front of me and fortunately no cars behind, I was in autopilot mode and emergency brake system got engaged for no reasons apparently (Phantom braking) and I had to take over immediately. It was scary and I was lucky that no car was behind as it could have created definitely a worse scenario. The first time I was entering a bridge and the color of the asphalt was a bit different from the main road that might have triggered this phantom braking. The second time I entered in a driving area in the shade, here the phantom braking might have been triggered by a sudden change in the sun light. Regards.

We were driving down the road, emergency braking enabled came on and car came to a complete abrupt start 10ft from railroad tracks and would not do anything. Could not reset it. Nothing.

My Tesla Model 3 was delivered on 14 December 2022. I first drove it on 16 December 2022 and that day I had an accident. I was about to park my car and I was already on the designated parking slot when the car made a sudden Un- commanded acceleration. I first hit the handicap sign, but the car did not stop and apparently the collision avoidance safety feature did not work. The continue to accelerate and I hit a restaurant establishment. The police came and I reported the incident to my insurance (Geico). The police (Mr. McClure) gave me the case number 2238293. Geico is taking care of the repair which would cost over $10K and the property damage, which added up to 10K. I went to the Tesla service center in Carlsbad and Mr. Hyuma said that I can request for the log. I guess it is the EDR. They gave me a link to request for the EDR but the start date is 23 January 2023 way after the accident date of 16 December 2022. I have not received any log or EDR from Tesla to date. I am uploading the pictures of the car before the repair. Please help me find out what exactly happened and why the car suddenly accelerated without pressing the gas pedal. I am a retired US Navy (20 years) and I bought a Tesla to save money because i have solar in my house. I have a fixed income and cannot afford to spend money on the EDR. I believe that here is a defect on the Tesla Model 3 that I bought and I will appreciate all the help you can provide.

sudden, abrupt braking on multiple occasions when passing a specific location along NJ Garden State Parkway (near exit 89) while driving on auto pilot.

Picked up car from the dealership same day and had only 40 miles total on odometer. The car was running smooth. I was driving with my daughter in the passenger seat (12 yrs old) and got 2 error codes and my car went limp in the carpool lane. Basically went into neutral. Deceleration from 75mph .I had to avoid cars next to me to get to the shoulder and was driving at most 30-40 mph hoping a car would not slam into my rear. By the grace of God I made it to the shoulder safely. “Acceleration and Top Speed Reduced” and “Automatic Emergency Braking is Disabled” were the two errors. I’d never been so stressed. That was highly dangerous and I’ve been reading online of several other Tesla owners suffering the same fate. Please don’t wait until someone gets injured or killed before making Tesla recall their cars. I’ve been hearing its the Rear Drive Inverter (Motor) that is faulty according to others online. The service center has not diagnosed the problem with my car yet but I think that is the same issue. I feel that Tesla is negligent and should be penalized for allowing these cars to be driven off the lot by unsuspecting customers.

While traveling on the interstate at 75+ mph, which the cruise control engaged, the vehicle emergency braked 2 times during on one trip. The first felt like a fluke, speed was reduced by 10ish miles per hour. The second time was terrifying. I was traveling approximately 77 mph on the interstate and out of no where my vehicle slowed down significantly. I was too scared of getting hit from behind to look at the speedometer to know how much it actually breaked but it felt like it dropped down to 30 mph out of nowhere. Luckily I was not on a busy stretch of interstate, the car behind me had enough time to slow down and there was no one else around. My husband and I were scared out of our minds, wondering why and how this happened. He immediately google and that is when we learned of 'phantom breaking" I have owned this car for less than a week and now I am scared to use cruise control. I don't even have the self driving or advanced auto pilot. Thank god no one was hurt. This is more than a safety issue, this could be life and death. I read that this particular issue has been reported more often lately. I reported the problem to Tesla but urge you to conduct an investigation that gets this matter resolved, not just for Tesla drivers but for the safety of everyone on the road.
