Service Brakes Problems of Tesla Model X - part 1

During a recent incident where a tire issue caused damage to the wiring harness for the parking brake, resulting in a parking brake failure notification on the screen, the vehicle would not stop or turn off. The vehicle displayed n for neutral on the dash, but the vehicle would drive forward unless the brake was depressed. In addition, we were unable to place the vehicle in park, which meant that we were unable to shut it off. The only way to stop the vehicle from driving on its own and crashing into something was to place concrete blocks under the tires! unplugging the 12v battery also had no effect! the vehicle kept driving as if it was in drive, and there as no way to stop it without placing the foot on the brake pedal the entire time or placing the blocks I referenced. The only way I was able to shut it off, was to pull what's known as the fireman's loop, which I'm guessing firemen pull in the case of an accident. I wasn't aware of this mechanism, and only learned of it after posting on numerous social media apps regarding this issue. This is a major issue, as we are talking about a moving and unstoppable car! Tesla needs to build some mechanism that allows the car to be shut off by the driver or to override the screen and place the car in park. Pulling this firemans loop and unplugging the 12v battery, required me being in front of the vehicle, risking my life, as the vehicle could've easily moved if the concrete barriers didn't stop it, and also required me taking 30+ minutes to remove components from the frunk, just to access these components!!.

I am writing to formally document a life-threatening mechanical failure involving my 2022 Model X on January 30, 2026. While my wife was operating the vehicle, it suffered a simultaneous and catastrophic collapse of all primary safety systems. During operation, the vehicle experienced a total loss of steering and braking control. This was accompanied by a rapid cascade of critical system alerts on the primary display, including “abs malfunction,” “stability control disabled,” and “steering assist reduced/disabled. ” most critically, the vehicle exhibited sudden unintended acceleration (sua), increasing speed in direct opposition to the driver’s physical application of the brake pedal. This resulted in a near-miss where the driver narrowly avoided a construction crew.

While driving a notification popped up, parking brake may not be applied while driving. This notification appears in rain or snow making me think it is weather related malfunctioning.

I own a 2019 Model X which I have been driving for six years without any driving issues. I did have a few incidents in which the screen went black while driving. That was scary - driving without controls. These issues reported to Tesla and were addressed by Tesla. Today I was pulling into a parking lot when all of a sudden my Tesla automatically accelerated to high speed. I could not control or stop the vehicle despite applying hard brakes. The car crashed through a metal fence and continued to accelerate through the wall of a building. The only reason it finally stopped was because the back tires got stuck on the ledge of the wall. The Tesla went through the metal gates and walls of the building, but the safety airbag never deployed. The car has been towed away and reported to the insurance immediately after the police report. There was no warning messages or indication prior to the incident.

I am writing to report and formally document a very serious and distressing safety incident involving my Tesla Model X that occurred for a second time, on [xxx]. While driving routinely into the parking garage at my workplace, my vehicle suddenly and violently stopped without warning. There were no obstacles, vehicles, or pedestrians in front of me. The abrupt stop caused my body and head to jolt forward with force, resulting in whiplash. I am still feeling dizzy, dazed, and disoriented, and I believe I may need to consult a neurologist as I have a headache from the whiplash. This is not the first time this has occurred. A similar but less severe incident happened previously while I was driving on [xxx] . At that time, I dismissed it as a possible glitch, but after this most recent and violent episode, I am deeply alarmed. I am extremely concerned about the safety of this vehicle. What if this sudden stop had occurred on the freeway, or while my two children were in the car? the potential consequences could have been catastrophic.

I own a Tesla Model X, and for the past two summers I’ve experienced a repeating safety-critical issue during hot weather. After driving for a period in the heat, multiple systems begin to fail. The car displays numerous warnings including: •“parking brake requires service” •“traction control disabled” •“stability control disabled” •“steering assist reduced” •“automatic emergency braking unavailable” •“regenerative braking unavailable” •“lane departure avoidance unavailable” when this happens, the steering wheel becomes very stiff and hard to turn, which severely affects my ability to drive and control the vehicle. I’ve brought the vehicle to Tesla service twice. The first time (when it was still under warranty), they said they couldn’t replicate the issue. The second time, I brought it in while the warnings were still active. Tesla only cleaned some sensors and returned the car, but the issue returned again recently with all the same symptoms. This only happens in hot weather. Once the car cools down, the errors disappear. This intermittent issue is difficult for the service center to replicate, but it presents a serious safety risk, especially because steering and braking functions are compromised. I believe this is a deeper electrical or software issue affecting multiple safety systems under thermal stress. The issue has not been resolved, and the vehicle remains dangerous to drive in high temperatures.

My 2016 Tesla Model X has a persistent and dangerous issue with the electronic parking brake. The brake frequently fails to disengage properly, and the car becomes jerky when attempting to move. When the vehicle is parked, a warning appears stating: “parking brake not engaged. Vehicle may roll,” even when the brake is set. This poses a significant safety risk, especially on inclines. Additionally, the driver-side door latch mechanism has failed again. Tesla previously repaired this exact issue and charged me, but the failure has returned. The door sometimes fails to latch securely or does not open and close properly, creating a safety hazard. These issues have made me concerned about the safety of driving or parking the vehicle. I believe these components should be investigated as potential manufacturing or design defects.

Based on thousands of posts, replies, etc, this seems to be a well known issue with this model/year Tesla as well as other years/models. It seems that the wheel sensor cable is not fastened properly, and over time, the cable runs against the tire, causing the internal wires to be exposed, this in turn causes numerous faults to occur, which includes causing abs, lane departure avoidance, traction control, stability control, abs, and regenerative braking to stop working. This happens while driving resulting in an immediate change in how the vehicle functions which could easily lead to a major accident while there are numerous forums where this issue is noted, below is one that details the issue with photos [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Now I know it's called phantom or ghost breaking. When in cruise control or in autopilot, in certain highway areas from 65 or 70, it breaks down to 25 mph. Cars behind gets dangerously close, as well as the royal scare face I get! there has been two major updates since I bought it, and it still does the same. Since, more or less, I know the highway spots where it happens, I'm ready for it. However, when traveling elsewhere I'm not that lucky. At those high speeds it cam potential cause harm or even death!.

My 2016 Tesla Model X (VIN [xxx] ) was manufactured in March 2016 according to the sticker on the driver door. My car is experiencing the same issue as the Tesla service bulletin #sb-17-33-002 under NHTSA's recall # 17v2600 when putting the vehicle into drive or reverse from park. Tesla is stating they can not perform the service work because there is no recall specifically for my VIN# even though the car is showing the same error messages on the diagnostics screen and showing the same symptoms and failure as the recall and service bulletin. The repair requires the replacement of the parking brake calipers which is a safety issue if not replaced which could result in not properly functioning when needed. The vehicle is available for inspection. The vehicle displays warning messages not to drive the vehicle, the parking brake is not released and could cause damage to the brake pads if driven, and to take to the Tesla service center. Tesla is proposing the same repair and solution as the recall / service bulletin and wants to charge me $1,500 for something that should be under the recall, especially since my car was manufactured during the specified timeline of Feb 2016 to oct 2016 and should fall under the safety issue with the same issue as the recall. This recall needs to include my VIN # and any Model X built during this timeframe. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2025 Model X has a feature commonly called "one pedal drive", where lifting pressure off the gas pedal causes regenerative braking force. This feature is *forced at all times, and is unsafe in slippery icy conditions, especially turns, especially downhill. I don't know if this is because of a malfunction of their regen-braking anti-lock (the abs equvialent), or because it's simply not possible to drive safely in slippery conditions with one-pedal-drive regen braking. . . But either way, this situation is unsafe. I urge you to investigate this situation, and consider issuing a recall requiring Tesla to perform a software update to give drivers the ability to turn off one-pedal-drive, for safety in snowy and icy conditions. Note: Tesla's owners manual for the model y recommends drivers disable one-pedal-drive by turning regenerative braking to low, but they have disabled the ability to do this on all model s/x cars 2020+. From their model y owners manual: "warning: in snowy or icy conditions, model y may experience loss of traction during regenerative braking, particularly when in the standard setting and/or not using winter tires. Tesla recommends using the low setting in snowy or icy conditions to help maintain vehicle stability. " here is a video example of this happening to a driver (not me) for reference. This is snow not ice, and not even in a turn or downhill. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On two occasions while driving using Tesla’s fsd, the brake has failed to engage in emergency situations after engaging the brake pedal. I have reported this issue to Tesla as part of a broader buy back request for my car which has had multiple issues and continues to have multiple issues. Tesla simply stated they could not replicate this issue and denied my buyback request. I do not feel safe driving this car around.

Episode #2 'near-death-experience" Tuesday[xxx] Tesla Model X "auto steer" abruptly stopped on [xxx] between 1. 10pm - 1. 15pm sent a message to Tesla around 1. 30pm, exactly the same scenario happened on [xxx]. Coming from [xxx] going to [xxx] , after 10-15 seconds, car stopped abruptly. I do not know what happened and still shaken from episode #1, this incident happened with in 2 weeks apart. After Tesla's review, it was noted that autopilot was not active at 1. 30pm. Tesla can't do anything about this incident, as it is under beta version and it is the responsibility of the driver to be aware of such situations and should take full control of the vehicle. At that time in this situation, what control I have to take immediate control of when car stopped abruptly. Luckily no vehicles were coming behind and survived second time. Laptop screen blank, pressed gas pedal, breaks and after 30-45 seconds, laptop screen started showing up on the left side panel and quickly drove from the ramp. Basically malfunction of the software and/or a glitch caused car to stop abruptly. Now. We are shaken and worried what to do and go to work and do other chores. We have two Tesla and we are totally lost, now what to do and what options to choose for driving. Based on details posted on internet and number of complaints filed, it looks like that no action has been taken. What are the next steps from Tesla's perspective and NHTSA? f in the last couple of years, more than 1500 hundred complaints have been filed, fatal accidents and people died. Your help is much appreciated so that more lives could be saved, information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I had a reoccurrence of incident 11609414. After the original incident I had my car towed to the service center and "fixed". I paid out of pocket since my warranty did not cover the problem they claimed that caused my issues. 5 weeks later I had the same issue recur, while out shopping. My car would not shift into park, the emergency brake failed, my seat restraint failed, my airbag failed, my abs failed, my steering assist failed. I had to stay in my car with my foot on the brake until I could get my car towed to the service center. Had I taken my foot off of the brake my car would have moved forward into a coffee shop filled with people.

Episode # 1: Sunday, [xxx] near-death-experience 2 times in 2 weeks while driving Tesla Model X 2023 with fsd. Both myself and wife were travelling and coming from toronto to lake george, NJ all of a sudden car stopped in the middle of the highway. Laptop screen was blank. In the mean time, turned on the emergency light. After a minute or so, white ute came (white) color came behind us with in less than a minute came from behind but he was able to steer on the left, honked couple of times and drove. I started panicking and do not know what to do and kept on saying what happened, what happened,,. . . . And at the same time, my wife asked me to pull car aside quickly otherwise someone is coming from behind is going to hit and that is going to be the end of our life (die) in a crash. Somehow started pedalling gas, break and then noticed laptop screen lightning up and quickly put the car in drive and pulled the car on the right hand side (extreme right) and no service lane. Pulled the car partially on road and partially on the road. Reached lake george late evening and stayed in sleep in & suites, queensbury, stayed over night, Monday and left sleep in on on Tuesday, [xxx]. I just drove couple of miles and was not feeling and was looking unstable and wife did not let me drive all the way from lake george to new jersey. As we parked our car at quick chek for a short break for few minutes. She noticed that instead reversing car from the car park and put car in drive and immediately applied breaks and at that time she did not let me drive. As soon as we reached back and went straight to our son's house and as our son is a dr. , and when told him about the episode he took me straight to jefferson's er worrying that I may have small strokes. Emergency admitted me in the hospital and started diagnostics e. G. , ctc, mri and other blood tests. Next day they released from the hospital and referred for a followup to neuro dr. Next day reported to Tesla. Information redacted pursuant to the freedom of information act (foia),.

We parked the car in our drive way. On the next day, car says display a `park break fault` message saying 'parking break did not release - driving may result in break damage'. When I push the park button, car console says 'parking brake not applied - vehicle my free roll'. I believe this is the same faulty issue that was recalled in NHTSA recall 17v-260, manufacturing recall sb-17-33-002. For reference, here is the link to that recall: [xxx] . Our car's model year matches the model year specified in that recall. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

When applying the brakes the steering wheel vibrates and car has reduced stopping power. When I took it to Tesla service center they said the "rotor runout is out of spec" the car has 25k miles and new "performance pads" were installed by Tesla as an upgrade in December 2023. The shaking developed after this. Tesla says the rotors are a wearable part and not covered under warranty.

On July 29, 2024, when my husband backed the vehicle out of the garage slowly, the vehicle suddenly accelerated and it hit the stone column causing a big damage to the car. I believe the pedal speed control and emergency brake have problems. When I reported to Tesla, they said the vehicle was not at fault. They said the issue had been resolved remotely by the engineer and cancelled my service appointment. When I asked for the engineer report, Tesla rep told me to download the data report. After I downloaded the data report, it shows no data 2 hours before and after the time of the incident. When I tried to retrieve the video on the replay function in the vehicle, the video was not there anymore. Fortunately, my husband recorded the video on his phone and I have a copy of the video. I feel very disappointed and frustrated with how Tesla handled the issue. If they are not at fault, how come the data report and video are not available? I filed a claim under my auto insurance policy and got the vehicle fixed. This sudden unintended acceleration happened to me back in June when the vehicle accelerated by itself to 41mph. My daughter, who was sitting next to me in the front passenger seat, saw my foot was in the air but the vehicle kept moving at 41mph. We were so shocked and I had to use both feet to step on the brake to stop the vehicle. Tesla eventually replaced the steering column control in the beginning of July. Then, on July 29, the sudden acceleration happened again to my husband. This safety issue needs to be addressed by Tesla more seriously. I should at least get a written explanation of what happened and not just a phone call telling me the vehicle was not at fault. Since the damage to vehicle is fixed now, we would drive the vehicle more often. I don't want this sudden unintended acceleration to happen again, hitting something or someone on the road!.

Description of the problem: component/system failure: on [xxx], while using the full self-driving (fsd) feature of my Tesla Model X, the vehicle experienced severe phantom braking and unexpectedly veered off the road near rio vista, antioch, CA. The failure appears to be related to the fsd system, braking, and steering. The vehicle is currently in Tesla’s possession and available for inspection upon request. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6) safety risk: the malfunction put my safety and the safety of others at significant risk. The sudden phantom braking and veering off the road could have caused a serious accident. Fortunately, there were no immediate external damages or injuries, but the incident highlighted a critical safety failure. Reproduction/confirmation: the problem has not been reproduced or confirmed by an independent service center. Tesla has had the vehicle for over three weeks, claiming to conduct a diagnostic check, but has not communicated any findings. Inspection: the vehicle has been inspected by Tesla, but no results have been shared. No inspections have been conducted by the police or insurance representatives as there was no collision or external damage. Warning lamps/messages: there were no warning lamps, messages, or other symptoms prior to the failure. The incident occurred suddenly and without prior indication of a malfunction. Summary: the incident highlights a severe malfunction in the full self-driving system of my Tesla Model X, posing significant safety risks. Tesla’s lack of communication and failure to provide a loaner vehicle during the extended diagnostic period is unacceptable. I am requesting NHTSA’s assistance in addressing this safety concern and ensuring a thorough investigation.

On may 30, on a 55 mph highway, my Tesla Model X was traveling at highway speed in thick traffic. The vehicle was using cruise control, but not auto pilot. In other words, the auto steering function was not engaged. A vehicle that the Tesla Model X was following came to a sudden, unexpected stop. I applied the brake pedal with full force. The anti-lock brakes engaged and the brakes began pulsing (normal anti-lock brake behavior). However, while the brake pedal was depressed with full force, the anti-lock brakes stopped pulsing and the brake pads disengaged from the rotors. The car coasted as if the brake pedal was not depressed. The brake failure resulted in a frontal collision with the stopped vehicle. A police report was filed at the scene of the crash. There were no physical injuries and the Tesla Model X was driveable after the incident. However, the car that was struck had significant damage (but no bodily injuries). Because the Model X was driveable, I attempted to recreate the incident 12 hours later. However, as I tested the brakes, they behaved normally. With the fully depressed brake pedal, the antilock brakes stayed active until a full stop of the vehicle. Is it possible that the frontal collision system malfunctioned? as the frontal sensors detected an impending crash, did the car's computer disengage the brakes mistakenly? the car had no warning lights prior to may 30. However, at the exact time of the crash, two codes were registered. (I used the Tesla service mode to access them). One code states the anti-lock brakes were active. The second code registered exactly 2 seconds later and states "pedestrian safety system fault". There is a police report, but we have not received it yet. I had to check no in the form because the form would not allow me to move forward unless I uploaded the report. I can upload the police report when I receive it.

8:40am Saturday Apr 20 I was driving southbound on hwy 121 in dallas, TX (near spring creek exit) in Tesla modelx, with 2 kids in the back seat. It is raining. My speed is around 60-65mph and I am in the rightmost lane. Suddenly the vehicle skids a little, and my steering wheel and brakes are not working anymore. It seemed that the car took complete control and does a full 360 rotation, crossing 4 lanes on the highway. I recall the 10 seconds when I am facing the incoming cars and the only thought I had "this is the end". For whatever reason, the incoming cars slowdown and my Tesla makes a full circle, crosses 4 lanes again and gets positioned correctly in the flow of the traffic and in the rightmost lane. My speed now is around 20-30 mph and I suddenly regain control of the brakes and the steering wheel. My kids are crying in the backseat. I still am trying to figure out how and what happened, I cant believe I am alive and I did cry thinking that anything could have happened to my kids. We could have all died on the spot given the rain and how fast the highway traffic goes. I am 47 and have been driving for about 30 years. I know how to control minor skidding in rain. I go skiing frequently and can drive on ice (but this was no ice, just water). The only explanation is the malfunction of the Tesla mirrors/cameras (perhaps due to rain water), and taking the wrong decision to swerve the car completely across 4 lanes back and forth. I wish nobody has to go through such life-altering experiences due to a car malfunction, I will never forgive Tesla for the nightmares I still get and the trauma I and my kids had to go through due to the error of a machine. There were no issues before or after with the car, no damage, our tires were relatively new, no police was called. Tesla of course must record incidences like this and they did call me and escalated this to their highest level.

This is regarding two Tesla recalls: - NHTSA recall number: 23v-838; tc2023-657 - NHTSA recall number: 24v-051 as noted in both recalls, they are to be delivered via software updates. My car is currently running version 2022. 8. 10. 16 7477b4ff8e78 which is clearly lower than the version required for both recalls. I have taken my car to service as my software version is not updating. Tesla has refused to comply with the recall and update the software version on my car. It should be noted, although irrelevant for the recalls, that my car is still under manufacturer's extended warranty, which we purchased along with the car when buying it new from Tesla.

On 1/12/24 at 12:55pm my 2020 Tesla Model X long range plus suddenly started braking while on the highway. I was driving 75mph to san diego from arizona. There was no vehicles around or in front while using the cruise control. This also has been an issue with our 2023 Tesla model y and previous model 3 while driving to las vegas at 70mph. I really think this is safety concern. Luckily there was vehicles behind us with all incidents that took place. I recently took the 2020 Tesla Model X on 1/19/24 for the issue and the technician found no issues while driving it.

Display mcu1 is unsafe or at end of life and unsafe locks up goes dark and unresponsive for long periods of time, unable to drive sometimes my my car is under warranty either they should fix it or upgrade it, I was told I need to upgrade it but my car is still under new car bumper to bumper warranty either fix it or replace it, if mcu1 doesn’t work then replace it with mcu2 and honor the new car bumper to bumper warranty.

I had an interaction with this vehicle on snow/ice packed i70 in colorado, almost to the kansas border. This car passed me, then immediately cut in front of my truck in the right lane and quickly slowed to about 10 mph with no warning. The car then pulled over onto the snow packed shoulder.

The brake pedal feels off due to low brake fluid.

I was the passenger in this Tesla. When we turned the Tesla accelerated and the driver tried to brake but she screamed to me they weren’t working. The Tesla slammed into the back of my parked SUV and pushed my parked car and us through the garage and my car through the back brick wall. We were both at high risk of possibly dying in the car crash. We suffered injurys and still are suffering. There has been a recall on the model Tesla’s brakes I will attach a picture. Some of the questions are unknown because I was the passenger of the car.

The contact owned a 2023 Tesla Model X. The contact stated that while driving into her driveway, the vehicle unexpectedly accelerated, and conversely, with the brake pedal depressed all the way to the floorboard, the vehicle failed to come to a complete stop. As a result, the vehicle collided with the rear of another vehicle parked in the driveway, sending the other vehicle careening into the garage. The air bags did deploy. A police report was filed, and injuries were reported. The occupants transported themselves to an area hospital for treatment; the contact was treated for a broken hand and two broken ribs, and the passenger was treated for bruising and a sprained ankle. No warning lights were illuminated. The vehicle was towed to a tow yard and deemed a total loss. The manufacturer was notified of the failure but provided no assistance. After investigating the failure, the contact related the failure to NHTSA campaign number: 23v679000 (electrical system, service brakes, hydraulic), but the VIN was not included. The failure mileage was 5,000.

I was driving the car in stop-and-go traffic on a city street. After another stop, the car in front of me started moving. I pressed on the accelerator with the usual force, but my car took off like crazy. I pressed on the breaks, but the car didn't seem to respond to the brake pedal and ran into a car in front of me. Automatic emergency breaking system didn't engage as well. Luckily, nobody was injured. Had there been any pedestrians crossing the street, they would have been badly injured or killed. This uncontrolled response from the car is very dangerous and I cannot trust it anymore. As a result of this accident, the car in front suffered damage in the amount of a few thousand usd, and my Tesla Model X - $40k.

To whom it may concern, my name is [xxx] , and I am writing regarding unresolved issues with my 2016 Tesla Model X (VIN: [xxx] ). Despite multiple service visits, extensive repairs, and approximately $8,000 in costs, my vehicle remains undrivable and presents significant safety concerns. I initially brought my vehicle to the Tesla service center in richmond, texas, for motor-related issues. I was informed that mismatched tires and front-end components were contributing to the problem, and repairs were completed. However, the original issue persisted. Subsequent visits for additional repairs also failed to resolve the problem, and new safety concerns emerged. Complicating matters, the richmond service center has since closed, and its staff were terminated. When I contacted the westchase service center, manager andrea p. Informed me that no resolution or agreement could be reached. I have attached the following invoices for your review: invoice #[xxx], dated April 26, 2024 invoice #[xxx], dated November 9, 2023 I am requesting the following: a full review of my service history and unresolved issues. Immediate repairs to address motor and safety concerns at no additional cost. A clear explanation of Tesla’s policies regarding unresolved repairs, especially with closed service centers. This situation has caused financial and personal hardship. I urge Tesla to address these issues promptly to restore my confidence in your brand. Please contact me at [your phone number] or [your email address] to discuss this matter. Sincerely, [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I initially brought my vehicle to the Tesla service center in richmond, texas, to address issues involving the motor. During this visit, I was informed that mismatched tire sizes and worn parts in the front end were contributing to the problem. The service center proceeded with repairs, charging me for the work. However, the original issue persisted after I picked up the vehicle. Despite multiple follow-up appointments and additional repairs, the problem was never resolved.

Using Tesla autopilot I was passing a semi truck on ohio turnpike and as I was right next to the semi truck my Tesla suddenly started to flash red warning light and make a loud squealing sound and began to rapidly decelerate. Luckily no one was right behind us or likely a rear collision would have occurred. The semi truck was a little closer than normal to me but was still within its lane. This happened twice that day so I stopped using autopilot as it was dangerous and very frightening to me and my passenger.

Brakes will lock up a pre collision will activate in forward and reverse when no objects are present. It is a hazard to operate the vehicle since it will randomly slam in the brakes will driving down the road or reversing out of a parking space. Also electrical issues vehicle will no longer lock or unlock.

The autopilot was engaged and the system failed, it james the breaks hard and it started scraping the body above the tire.
