Service Brakes Problems of Tesla Model Y - part 1

Screen provides alert that "center brake light condition deteceted". Shows up as vcright_a487. Tesla has said it is a software condition that will be fixed in an update, yet several updates later, the condition persists with no fix in sight. This error has appeared since the time of new vehicle delivery in early may 2026 to the present.

Fsd (supervised) was engaged while the vehicle was traveling toward a freeway entrance. The vehicle was expected to turn right, but instead began veering left. The driver applied the brake in an attempt to slow the vehicle and disengage fsd. According to the driver’s recollection, the vehicle did not respond as expected and continued accelerating until it left the roadway and crashed into a ditch. The incident created a serious safety risk to the driver and an infant passenger. Emergency services responded, and the driver and infant passenger were transported to an emergency department for evaluation. The vehicle was subsequently towed from the scene. The suspected malfunction involves fsd/vehicle control behavior, including whether the system properly responded to brake input and whether commanded acceleration continued after the driver attempted to intervene. The vehicle and its electronic systems should currently be available for inspection, and a request has been made to preserve relevant vehicle telemetry, driver-input data, fsd engagement status, accelerator and brake inputs, commanded motor torque, speed, steering inputs, camera footage, event data recorder information, diagnostic logs, and software/fsd version information. A police report has been filed and both Tesla and Tesla insurance have been contacted.

On August 15, 2026, at approximately 5:00 pm, the vehicle was being driven with full self-driving (supervised) engaged during light rain. As the vehicle approached traffic ahead, it did not slow or brake as expected. The driver recognized that the vehicle was not slowing and attempted to intervene manually by pressing the brake pedal multiple times. The driver reports that despite these attempts, the vehicle did not slow or respond to the brake pedal as expected, and a collision occurred. There were no known warning lamps or warning messages indicating a braking-system problem prior to the incident. The vehicle has not yet been inspected to determine the cause of the reported braking behavior. The incident has been reported to the manufacturer, and a request has been made to preserve and review available vehicle data surrounding the collision, including braking inputs, vehicle speed, full self-driving status/actions, warnings, diagnostic information, and safety/event data. The vehicle is available for inspection. At this time, the cause of the failure to slow as expected is unknown.

My Tesla Model Y was driving on fsd (full self driving) and just did hard full stop brake at a traffic light and brought the car to a complete stop even when the light was green. Both of toddler kids in the back got pulled jolted forward where the seat belt hurt them. This stopping was random was unnecessary as no threat of other cars or the light was present. Luckily no one was behind us or they would have rear ended our car causing a serious accident. This really left my children in shock.

2026 Tesla Model Y (VIN [xxx]) running fsd supervised v14. 2. 2. 5 / software 2026. 14. 200 experienced two unintended phantom braking events while fsd was active. Incident 1: xxx, approximately 9:16 am, xxx southbound off-ramp at [xxx] exit heading [xxx]. Vehicle braked abruptly and without warning at highway approach speed with no obstacle present. Incident 2: xxx, approximately 2:08 pm, [xxx] westbound atxxx northbound on-ramp [xxx]. Same abrupt, unwarned braking with no obstacle present. Tesla service performed diagnostics xxx, at the delray beach service center. No hardware fault was found. Vehicle has been unable to receive ota software updates. A nearly identical vehicle, a 2026 Tesla Model Y in the same household (VIN [xxx]), is currently running software 2026. 20. 6. 11 and fsd v14. 3. 6, several versions ahead of the affected vehicle. Tesla confirmed the software disparity is due to VIN batch rollout scheduling and cannot be manually accelerated. Tesla regional management and engineering review team have been notified. While children were not in the vehicle at the time of these specific incidents, they are frequent passengers in this vehicle and this braking behavior represents a serious safety concern for our family.

My car will randomly break while I’m driving straight on a road. It seems to happen when I’m going between 30 and 45 mph. It breaks so hard that if a car behind me was following, they could run into me. Whenever it breaks, I have to put my foot on the accelerator to get the car to go back forward.

I was driving at approximately 30-35 mph on a 30 mph residential road with my son in the front passenger seat. My vehicle unexpectedly collided with a parked, unoccupied car on the right side of the road, impact occurring between my front passenger side and the rear driver side of the parked vehicle. Following the initial collision, the vehicle continued past a small tree, mounted the sidewalk, and struck a second parked car before I was able to manually bring it to a stop 2–3 houses further down near an intersection. Throughout this sequence—with the vehicle traveling at ~35 mph—neither the automatic emergency braking (aeb) activated nor did any airbags deploy. Fortunately, neither my son nor I sustained catastrophic injuries, though my chest struck the steering wheel during the impact, causing ongoing pain my and mental trauma for my son. I am currently receiving medical advise. Given the speed and sequence of impacts, it is terrifying that the vehicle’s primary safety systems failed to engage before, during, or after the collision. I am seeking a thorough technical investigation into why automatic emergency braking and airbag deployment failed in this scenario with Tesla Model Y.

I was pushed to complete an update on my 2023 Tesla y with an over the air update. This happened last week. Following the update I have been getting a slew of errors when driving my car related to the parking break, brake functions, automatic energy braking and steering are affected. The wording on the app / car says, alerts - steering & braking - parking brake functions degraded / parking brake may not apply or release / parking brake may not apply or release. This causes my auto brake to not engage, my hold break to not engage, my parking brake to not engage. This causes my car to roll at stop / red lights. I have to physically slam by brakes to stop. This is extremely unsafe and Tesla is trying to charge me $130 to diagnose the car to see why the update caused the issue. My car went from fully drivable without any fsd, normal driving to a runaway trainwreck. This happens roughly 20-30 minutes randomly into driving. Not immediately and it is completely random.

**incident report — Tesla Model Y safety system failure** the subject vehicle, a Tesla Model Y equipped with full self-driving (fsd) technology and advanced safety features, was involved in a collision at an estimated impact speed of 40–45 mph. The vehicle's onboard recording system captured the incident and clearly documents the impact dynamics, vehicle speed at impact, and the contributing actions of the other party involved. **incident details:** - **impact location:** left front side of vehicle - **impact speed:** 40–45 mph - **damage assessment:** vehicle declared total loss by insurance - **recorded evidence:** onboard system footage available **safety system failures:** despite the severity of the impact and speed involved, the following safety systems failed to activate: - emergency braking system did not engage - forward collision warning failed - seatbelt pre-tensioning/locking mechanism did not activate - airbag deployment systems failed (front, side, curtain, and knee airbags) **concern:** the vehicle's advanced safety features—which are primary design components marketed for collision mitigation—did not function as designed or expected. Given the impact speed and severity, these safety systems should have either mitigated the collision or deployed to protect occupants. The failure of multiple redundant safety systems raises questions regarding the reliability and function of these critical systems at the time of impact. **available evidence:** - onboard system footage (speed, impact angle, timing) - insurance total loss assessment - medical records (if applicable) - vehicle service history.

I purchased a new 2026 Tesla Model Y standard and took delivery on approximately 30 may 2026. Within the first week of ownership, the vehicle displayed multiple safety-related warnings, including: * steering assist reduced * power braking assist reduced * automatic emergency braking unavailable * lane departure avoidance features unavailable * automatic vehicle hold disabled the warnings have occurred more than once. They initially disappeared and then returned on a later drive. Both incidents occurred while the vehicle was operating with full self-driving (fsd) engaged. During the most recent occurrence, while parking at less than 3 mph, the vehicle’s braking assistance appeared reduced and the brake pedal required significantly more effort than normal. As a result, I nearly struck a curb because the vehicle did not slow as expected. The warnings indicated that increased steering and braking effort may be required. Because the vehicle is brand new and these warnings involve steering, braking, and collision-avoidance systems, I believe this creates a significant safety risk. I no longer feel the vehicle is safe to drive until it is inspected and repaired. Tesla has been notified and a service request has been initiated.

Phantom brake incident today,5/26/26. Traveling 35mph, brakes slammed on for no apparent reason. Seatbelt tightened and my head launched forward. Neck is very strained.

A 2023 Tesla Model Y experienced a sudden electrical failure while parked/being prepared for use. Multiple warnings appeared on may 26, 2026, including high-voltage system service required, low-voltage electrical system power reduced/vehicle shutting down, cabin climate control limited, and steering/braking/parking brake functions degraded. The vehicle could not be driven normally and required flatbed recovery. The failure created a safety concern because the vehicle showed high-voltage and low-voltage faults together with steering/braking/parking brake warnings and could have left the vehicle disabled without reliable restart or parking brake function. The manufacturer service center inspected and repaired the vehicle after several days. The component should be available through manufacturer service records, and screenshots of the warnings, tow/recovery, and service records are available.

I was driving my Tesla in self drive mode, and ibecause it started raining. I reduce the speed to standard. I had a notification on the screen, an alert in red. That the Tesla reached the maximum speed in that mode “standard”. I was surprised and decided ti canceled the fsd feature and took control of the vehicle. Then when I was driving in the expressway very close to my exit on the right lane, the car accelerated by itself and turn to the left unexpectedly. I tried to returned the car to my lane and I never had control again of the car. Not the steering wheel, not the breaks responded. I was spinning on the expressway until I hit the concrete barrier with the rear bumper. Hopefully I did not hit any car nor they didn’t hit me. The car shutdown after the impact. Tesla sent me the footage of the impact, ignoring the moment that caused that incident that was some seconds before. The brakes were automatically turned onz and the wheels did not move. I know something wrong happened. Specially because the incident some minutes before when I was driving in standard mode and accelerated with no reasons. I have safety concerns. Also I noticed that after the last upgrades the car was havung navigation issues that I reported immediately when the autopilot was removed and we have to select the options.

Am reporting a serious safety concern involving a 2025 Tesla Model Y, VIN [xxx] . On [xxx], the vehicle was being driven on [xxx] in columbus, ohio while the driver was traveling to columbus preparatory academy. During the trip, the steering reportedly stopped responding properly, and the driver struggled to control the vehicle. Witnesses at the scene reported that the driver appeared to be fighting with the steering and trying to stop the vehicle or prevent it from drifting. The vehicle then lost control, accelerated or continued moving uncontrollably, flipped/rolled over, and sustained major damage. A police report was created by the columbus police department under report number [xxx]. The vehicle involved is a 2025 Tesla Model Y. This was a serious crash involving a possible steering malfunction, loss of control, and rollover. The vehicle is currently located at pro-cars, 400 stimmel rd, columbus, OH 43223. Tesla was contacted after the incident, and the representative advised that the vehicle should be taken to a collision center. I am filing this complaint because the incident appears to involve a potential safety defect affecting steering control and vehicle control. I request that NHTSA review this matter as a possible vehicle safety defect. The vehicle has not yet been repaired, and I am attempting to preserve it for inspection. I have supporting materials including the police report, photos/videos, witness information if needed, towing/storage documentation, and communications regarding the vehicle. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I have written several times before about my car's phantom braking in cruise control. When the santa fe Tesla dealer, where I bought the car, told me recently that the problem had been fixed, I was disappointed they didn't bother to tell me, but thrilled to hear the news. On may 12-13 I drove over 900 miles. I tried cruise control for significant portions of both drives and did not experience one problem. Finally, I thought, they fixed the problem. . . And how nice it was to have cruise control for extended drives. Not so soon: on may 19th I was driving 2 friends up to volunteer at the wildlife refuge on I-25 in northern new mexico. The phantom braking happened again. My friends were dismayed. . . One thought I had seen something in the road that she didn't see. The other, in the back seat, tried to understand what happened. Please, this is beyond the pale! of course I will call and take the car in to the dealer. . . An hour's drive for me. I will be surprised if they fix it, and if they do it under warranty. I did just buy new tires (see previous report about original tires with multiple flats and not even making it to their 40,000 mile warranty) so I'm no longer worried about getting a flat in the rural areas where I live and drive.

Service concern — front suspension / rattling noise vehicle is experiencing a persistent rattling/knocking noise from the front area when driving over bumps, uneven pavement, or rough roads. Noise is noticeable at low to moderate speeds and appears suspension-related. Condition seems consistent with known Tesla Model Y service concerns regarding: * front upper control arm mounts, * front damper assemblies, * and wiper bracket pencil braces. Requesting inspection and evaluation * front suspension components, * damper assemblies, * upper control arm mounts, * and any applicable Tesla service bulletins related to front-end nvh/rattling concerns. Noise has become increasingly noticeable during normal driving conditions and is affecting ride quality. Please document findings and advise whether repairs are covered under warranty. The symptoms typically include: * rattling noise over small bumps * knocking or clunking from the front suspension * noise on rough pavement, speed bumps, or uneven roads * sometimes vibration or looseness felt near the dashboard/firewall area the repair procedure mentioned is consistent with a Tesla internal service approach for addressing front-end nvh issues (noise, vibration, harshness). Here’s what each item means: front upper control arm mounts these are suspension mounting components near the top of the front wheel assembly. If worn, loose, or improperly isolated, they can create: * metallic knocking * clicking during suspension travel * vibration transferred into the cabin replacing them helps stabilize suspension movement. Front damper assemblies the dampers (shock absorbers/struts) control suspension rebound and compression. Faulty or noisy dampers can produce: * hollow clunks * rattles over expansion joints * repetitive knocking on rough roads replacing the assemblies usually resolves internal damper noise. Wiper bracket “pencil braces” these braces sit beneath the cowl/wiper assembly area. On some vehicles they c.

Car makes loud noise from front axel.

The contact’s wife owned a 2022 Tesla y. The contact stated that while the vehicle was parked, his wife shifted the gear shifter into drive(d), and the vehicle independently accelerated. The autonomous feature was not engaged. The brake pedal was depressed; however, the vehicle failed to respond as needed, and the front center of the vehicle crashed into a pile of cinder blocks, drove through a gate, and crashed into a dumpster, where it came to a stop. As a result of the impact, the front driver's side tire detached, and the dumpster was damaged. The contact stated that another person helped remove the driver from the vehicle due to the front driver door being unable to open. The air bags deployed as intended. No warning lights were illuminated. The vehicle was towed to a tow yard and was deemed a total loss. A police report was filed. The driver had pain in the back and sought medical attention. The contact's wife was informed of a slight fracture of an unstated bone in her back and ribs, and had to return to the doctor several times for medical assistance. The contact was certain there was no user error to have caused the crash the manufacturer was notified of the failure. The failure mileage was unknown.

Purchased used 2023 Tesla Model Y from Tesla on April 17, 2026 at ~16,300 miles. Pre-delivery, Tesla notified me by text that the vehicle failed state safety inspection due to front upper ball joint play (a known Tesla model 3/y defect). Tesla repaired it at its own service center and certified it as passing on April 8, 2026. No warning lamps or messages. ~12 days post-delivery a family member reported a noise from the left rear; the vehicle was then parked. On may 10, 2026, I removed the left rear wheel and found the left rear brake caliper completely detached from the rear knuckle. Both caliper bracket mounting bolts were missing. The caliper was held only because it had seized on the rotor. Vehicle unsafe to operate. Towed by flatbed to Tesla may 11; available for inspection on request. Properly torqued caliper bracket bolts do not back themselves out in ~800 miles of light use. Realistic causes: (a) bolts installed but not torqued to spec, worked loose in service; (b) bolts missing at state inspection and certified anyway; (c) suspension disassembled during the pre-sale repair, bracket reassembled with bolts omitted. All implicate Tesla's workmanship; (b) and a visibly-loose (a) also implicate the inspection. Tesla previously acknowledged this failure mode in recall sb-21-33-002 ("loose brake caliper bolts," 2019-2021 model 3 / 2020-2021 Model Y): caliper bolts "may not be torqued to internal specifications" and "may be loose, allowing the brake caliper to separate. " my vehicle is outside that range but the recall shows this is a known Tesla pattern. Risk: caliper detachment can wedge the wheel, lock the brake, damage tire/wheel, boil brake fluid, or break free at speed — any can cause loss of control. Vehicle driven ~800 miles in this condition. Dealer confirmation pending; Tesla instructed in writing not to repair pre-inspection. State police ased complaint filed; formal dispute filed with Tesla resolutions.

Our 2022 Tesla Model Y long range had a braking system failure due to a flawed routing of the rear flex brake lines. When applying the brakes at a red light the vehicle rolled into the intersection despite the brake pedal being pressed to the firewall. There were no warning lights at this time. After arriving home, large amounts of brake fluid were visible under the car. I removed the rear passenger side wheel to inspect the source of the leak. It was immediately clear that the flexible brake line was the source of the leak. It was installed (at the factory) in a position that allowed it to rub against the thin and abrasive edge of the wheel well. Over time, this cut into the brake line until a hole formed. The same issue was occurring on the rear driver side brake line. I took the car to a Tesla service center where they insisted that this was not a Tesla issue. They claimed that the faulty routing of the brake lines must have occurred within the last three weeks, and that they had never heard of this happening with another Tesla. Only after they looked at the problem did a brake warning appear on the screen showing there was a problem. I paid an independent service center to replace the lines and reroute them. I’m filing this report because I’m worried there are other customers, (especially those that have Model Ys that came off the line when mine did) driving around unaware that their brakes may fail when they need them most.

There was a grinding sound coming from the lf wheel. This was progressively getting worse. Car was shaking while driving so dropped it off with my mechanic due to safety concerns. Per the mechanic that fixed the issue: inspection found lf wheel bearing is loose. A bolt backed out on inside rubbing through axel shaft. Allowed wheel bearing to damage to damaged from moving in place. Axle shaft damaged from rubbing on backed out bolt. Replace lf axle shaft and wheel bearing. Informed by mechanic that wheel could have fallen off while driving. No prior work. Mechanic believes most likely issue was not having the bolts appropriately installed at time of manufactue.

The rear subframe wiring harness on my Tesla contains a significant design flaw that creates an unreasonable safety risk. The factory-installed corrugated protective tubing (wire loom) terminates prematurely, leaving approximately 1 inch of critical wiring completely exposed at the connector. This specific harness uses soy-based insulation, which is a known attractant to rodents. Because of the 1-inch gap in protection, rodents have been able to sever the same connector twice within a 30-day period safety risk: the exposed wires in the rear subframe harness are responsible for rear drive unit communication / wheel speed sensors / brakes]. A failure of these wires while the vehicle is in motion could result in a sudden loss of propulsion, unexpected braking, or the loss of stability control systems. This creates a high risk of a collision, particularly at highway speeds.

On April 11 2026, I was involved in a serious accident involving my 2026 Tesla Model Y. At the time of the incident, I was returning home from my daughter’s event in downtown and had just entered my residential driveway. As I approached the driveway, I applied the brakes and slowed the vehicle. While momentarily stationary or near-stationary, I spoke to my wife, who was seated in the front passenger seat, advising her to secure the food she was holding due to the uneven surface of the driveway. Upon removing my foot from the brake pedal, the vehicle suddenly and unexpectedly accelerated without any input . The vehicle proceeded forward and collided with my garage door. Notably, no collision warning alerts were issued, and no automatic emergency braking system engaged prior to or during the impact. Following the initial collision with garage door, the vehicle failed to stop and instead continued to accelerate into the garage, striking a refrigerator. The impact resulted in substantial damage to the refrigerator and caused extensive structural harm to the property, affecting the garage, adjacent living space, floors, and interior walls. The severity of the collision triggered deployment of the front airbags. At the time, my wife was seated in the front passenger seat, and my [xxx] daughter, along with her friend, was seated in the rear of the vehicle. Emergency services were called, I have forehead bruises and a burn on my hand from airbag deployment. My wife is advised physiotherapy for severe back pain and my daughter has since experienced ongoing emotional distress, nightmares. I am dealing with car and home claims issues for damages I am seeking a formal investigation into the cause of this incident, specifically addressing: 1)the unexpected and unintended acceleration of the vehicle 2)the failure of the vehicle to stop after the initial collision with the garage door 3)the absence of forward collision warnings and failure of automatic emergency braking . Information redacted pursuant to the freedom of info.

I am reporting a serious safety concern involving my Tesla Model Y. While driving, the vehicle’s main center screen (mcu) suddenly failed and entered a continuous reboot loop. This resulted in the loss of critical driving information and controls, including navigation, camera display, and vehicle system status. The issue occurred without any warning and nearly caused a serious accident, as I was unable to safely monitor essential driving information. This failure made the vehicle extremely unsafe to operate. The problem appears to be related to a known mcu system failure affecting some Tesla vehicles. I am concerned that this issue may present a broader safety risk for other drivers. Please investigate this matter for potential safety defects.

On March 23, 2026, my vehicle experienced a sudden and simultaneous failure of multiple critical safety systems without any prior warning. The alerts displayed included: automatic emergency braking unavailable, traction control disabled, stability control disabled, and additional driver-assistance features becoming unavailable. This incident created a serious safety hazard, as the loss of these systems significantly reduces vehicle stability and braking assistance, increasing the risk of loss of control, especially at highway speeds or in adverse weather conditions. In addition, the front-facing camera exhibits fogging and reduced visibility during cloudy and rainy conditions, which further impacts the reliability of safety and driver-assistance systems. Based on my research, similar issues have been reported by other Tesla owners, suggesting this may not be an isolated incident but a potential pattern defect. I am concerned about the safety of operating this vehicle and request that this matter be investigated for potential defects affecting critical safety systems.

I was entering the on-ramp to [xxx] , from [xxx] , to merge onto the freeway east bound towards [xxx] , when my Tesla suddenly lost all power, the brakes did not work and the power steering completely failed making it feel like it was locked up. I was traveling approximately 40-50 mph at the time nearing the gore point to merge onto the freeway. Fortunately I was in the inside lane and I rolled to a stop away from other vehicles. I could not steer at all. Had I been completely on the freeway, I could have been rear ended badly. I had my two young boys in the vehicle with me, both [xxx] and [xxx] . We were completely trapped in the vehicle with no power. My [xxx] old remembered to use the manual latch to get out. I opened my door manually and it broke my driver side glass window. Vehicles were passing us rapidly to enter the freeway. I called my husband who is a police officer and he came and picked us up. We called Tesla who said they could not get a read on our battery whatsoever. We called a tow company and had this vehicle towed to Tesla repair center in [xxx] , after reporting our traumatic event. They claim our warranty is expired, but our vehicle only has 37,638 miles and should be covered under the 8 year, 120,000 mile warranty that covers a major malfunction like this.

Following a "secondary" botched windshield replacement within 3 weeks performed by the Tesla service center in carle place, NY, my Tesla Model Y experienced a catastrophic structural water intrusion during rainfall. A great amounts of water dripping directly through the windshield seal into the cabin, soaking the dashboard electronics, floorboards, and much more water coming in from the brake pedal area while driving on lie. While I was driving the vehicle with my three children in the back seat, this water intrusion triggered an active electrical short circuit. The vehicle's hazard lights began flashing autonomously, and the electrical system became severely compromised, creating an immediate and life-threatening safety hazard on the road. The vehicle is currently grounded, completely undrivable, and poses a continued electrical fire risk. Tesla service has been notified in writing and has officially acknowledged via their app that the vehicle must be towed. This gross negligence in structural sealing has directly compromised the vehicle's electrical control modules, severely endangering the lives of the occupants. ".

I've noticed periodically when the car is braking at start stop traffic in autopilot mode, the brake is very jerky and I can actually hear the pedal jerking and engaging. I wrote it off at the time in my head as normal operation of the car. I have brake pressure offset codes and brake booster mia codes. Sometimes I've noticed when I brake, randomly the pedal is super stiff and it feels like the car is driving on ice, as if the brakes aren't working or slowing me down at all, but I thought nothing of it at the time. Today on the 14th, I got into an accident at a relatively slow speed that in any other scenario I should have been able to stop. Yet I hit a parked car because as I was braking, I felt the pedal go very very stiff and unresponsive, and I carried the same speed as when I started braking right until impact, it seems as if I didn't slow down one bit. The brakes did not respond as they did mere seconds before and I hit a parked car. I understand Teslas may throw codes left and right in service mode that may mean nothing, but I am worried about the brake booster code and wonder if maybe it caused the accident I was involved in. My friends told me they heard about Tesla brake issues and that I should look into it and when I went to go check the codes hours later there they were.

Incident date?March 07, 2026] current mileage, 31625 miles ? I am reporting a catastrophic structural failure of a safety-critical suspension component on my Tesla Model Y. ?upon inspection, I discovered that one of the bolts securing the driver-side lower control arm has completely detached and fallen off. A second bolt is approximately 50% loose. This has caused a significant safety hazard, as the control arm is no longer properly secured to the subframe, leading to a high risk of total steering loss and wheel detachment while driving. ?furthermore, when I contacted Tesla service, they demonstrated extreme negligence by instructing me to drive the vehicle in this lethal condition to their service center. They also initially refused to cover the towing and repair costs, claiming it was not a factory defect despite the clear evidence of fastener failure (improper torque or thread locker application during manufacturing). ?this is a clear manufacturing defect that poses an immediate threat to the driver, passengers, and other road users. I am requesting NHTSA to investigate this batch of Model Y vehicles for suspension fastener integrity issues to prevent potential fatal accidents.

The vehicle was delivered with a critical safety defect in the braking system and inoperable safety software (gps/fsd/navigation). Upon further inspection by the dealer's own technician, it was confirmed that the vehicle had 'extremely poor brake feel' and 'extreme rust build up' on all pads and rotors, which violated Tesla’s 6mm minimum safety standard for used vehicles. Additionally, a physically damaged windshield harness caused the failure of gps and fsd features. These defects posed a significant safety risk to myself and my family during operation. The dealer has documented and confirmed these safety issues but is now refusing a buyback and is retaliating with storage fees for my rejection of the unsafe product. No warning lights appeared prior to the technician's discovery of the brake defects.

I was at full stop on [xxx] facing [xxx] at a red traffic signal at intersection. Then while still at light which was red the vehicle unexpectedly accelerated toward [xxx] on its even with feet on brake, I attempted to maneuver to avoid colliding with vehicles traveling on [xxx] , then made a sharp right turn on sidewalk of [xxx] drove striking a "bee line bus" sign located in front of [xxx] . I was able to maneuver not hitting any pedestrians and crashing vehicle out a brush on sidewalk without putting passengers/family in car at risk of injury information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On February 17, 2026, around 4:20 pm, as I was departing my agency's parking garage structure, my 2023 Tesla y uncontrollably and un-prompted accelerated at a very high speed. I applied the brake and it would not stop. I nearly killed the security guard at the garage who was trying to direct my vehicle to the correct exit lane. The vehicle ran across a sidewalk adjacent to the garage, ran across a street, hit a street parking meter, ran across another sidewalk, ran across and toppled a perimeter fence around a parking lot across from the garage I exited, ran over concrete wheel barriers, and continued running for about 300 feet before it came to a stop on its own. This duration of this terrifying ordeal was 3 to 5 seconds. The air bags did not deploy. I called 911 repeatedly for police investigation and report but the police never showed up. I towed the vehicle to a Tesla collision center, which inspected and investigated the accident, and the Tesla center stated that the fsd system was working properly and did not find anything wrong. I informed the Tesla center that I did not subscribe to the fsd system service and was not using it during the accident, and they stated that they stand by the determination of their engineering division that reviewed the "blackbox", information gathering device of the vehicle. The vehicle was totaled and non-salvageable. Prior to the accident, the Tesla collision center, had repaired the vehicle from a previous accident that occurred on September 25, 2025. There were no warnings before the vehicle uncontrollably accelerated at a very high speed. I have copy of the accident videos. Your platform would not allow me to upload the videos.

The contact owns a 2026 Tesla Model Y. The contact stated that while driving at approximately 10 mph into a parking spot, the contact depressed the brake pedal, but the vehicle failed to stop. The vehicle drove over a parking bump, struck a bench, and the automatic emergency braking system engaged, preventing the vehicle from hitting the wall. The air bags did not deploy. The contact stated that she had back pains, but was unsure whether they were related to the failure. There was no medical attention received. A police report was filed. The vehicle was able to be driven away from the crash site. The vehicle was taken to the dealer, who test-drove the vehicle. The contact was informed that the vehicle was not equipped with a manual parking brake; however, the brakes were functioning normally according to the computer, and to wait for corporate's report before taking the vehicle to a collision center for front-end repairs. The vehicle was not repaired. The manufacturer was made aware of the failure and opened an investigation. The contact was informed that the vehicle was safe to drive. The failure mileage was approximately 6,000.

It was snowing and I was driving slow. About 8:40am, Feb 6th, 2026, I got a "one pedal driving disabled" alert just for a moment, then tried to stop before an intersection because a signal was turning to red. However, break didn't work and I had to enter the intersection under a red signal. Fortunately, there was no car in front of me, also a car coming from the side didn't notice signal changed. No accident, but very very scary. On Dec 6th, I also got an alert "one pedal driving disabled" and even after I released an accelerator pedal, speed didn't slow down. I reached Tesla on Feb 6th, but the service scheduled 4 weeks later. It's not safe to drive at all, thus, I will try to have them to check my vehicle ASAP.
