Service Brakes Problems of Tesla Model Y - part 1

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.

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 .

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).

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.

While driving, the front left brake caliper detached, causing immediate damage to the wheel and a tire blowout. There was no recent brake, wheel, or suspension service (over two years). Tesla is repairing the vehicle for an estimated $2,336. 41 but did not clearly identify root cause. This was a sudden brake system failure that could have resulted in loss of control. I am reporting this as a potential safety defect.

We live on a road with a steep embankment. My wife backed across our driveway and when she put the car from reverse to drive it accelerated uncontrollably. She hit our mailbox, then a power pole across the street, a driveway across the street then over the embankment where she hit a retainer wall another wooden railing and finally came to rest against our neighbors house. If she wouldn’t have caught the edge of the house she would have went down approximately 150 foot embankment. Not only the car accelerated on its own it is supposed to automatically brake, it didn’t and the airbags never deployed. This all this happened right after it went through an automatic update. The car was totaled, with my wife getting a concussion and a lot of muscle injuries. There was no warning lights prior to event and we reported it to Tesla and all they did was send camera images which we had. The car is now in possession of wawanesa insurance because it was a total loss.

When driving with cruise control engaged the car randomly brakes and shows a "curvature assist " indication. The car quickly slows from 55 to 35 with no warning. This primary happens on a straight road, not a curve. I am concerned about the traffic behind me.

Any time you drive my vehicle there’s either violent shaking in the brake pedal, steering wheel, tires. When you try to brake it stutters. Using fsd it failed to stop instead almost hit a pedestrian on scooter and reported the time and date to Tesla. It stuttered and thank god I was able to jam in brakes. After 9 service visit the admitted they missed something and wheel alignment was off and tires were cupped. Along with a bracket for suspension. Which has not solved issues. It scary driving this vehicle especially as a single father who has to make long trips in the weekend for hockey.

Picked up car from Tesla service on 12/30/2025. On [xxx] at around [xxx] I had pressed the car break and suddenly accelerated and lead to crashing into the pole. I am concerned about the safety and if it is drivable. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am writing to formally report a serious safety incident involving a Tesla vehicle and to document multiple critical system failures that occurred during an accident, resulting in physical injuries to me. On the 12/24/2025, while operating Tesla under rainy conditions, I experienced a sudden and dangerous malfunction of the vehicle. During the event, the steering system became unresponsive and appeared to lock, preventing me from maintaining control of the vehicle. Simultaneously, the braking system failed to respond as expected despite my attempt to apply the brakes. These failures significantly impaired my ability to avoid or mitigate the collision. Most concerning, the vehicle’s airbag system did not deploy during the impact. Given the severity of the collision and the resulting injuries, the lack of airbag deployment represents a serious failure of a critical safety system designed to protect occupants in such events. As a direct result of this incident and the apparent malfunction of multiple safety systems, I sustained physical injuries that required medical evaluation and treatment. Beyond the physical harm, the incident caused significant emotional distress and raised serious concerns about the safety and reliability of the vehicle. I am submitting this complaint to formally document these safety failures and to request a thorough investigation into the performance of the steering, braking, and airbag systems involved in this incident. I believe this matter presents a significant safety concern not only for myself but also for other drivers and passengers who rely on these systems to function properly in emergency situations. Please confirm receipt of this complaint and advise me of the next steps in your investigation process. I am prepared to provide additional documentation, including medical records, photographs, vehicle data, and incident details, upon request. Thank you for your attention to this serious matter.

There is a serious safety-related fsd (full self driving) fundamental design flaw with stop sign behavior. On previous versions and on the latest and best version of fsd (currently that is v14. 2. 1. 25) when fsd approaches a stop sign and there is no white painted stopping line, fsd will make its full initial stop (also called the zero-speed stop) directly at or behind the stop sign instead of making the initial full stop beyond the stop sign at a location where the driver can see cross traffic. Sometimes the fsd initial full stop is 20, 30, 40, even 50+ feet back away from the edge of the road. At these distances from the edge of the road, most of the time, there is no visual of cross traffic left and right. The fsd stop then turns into the fsd "creep" where fsd, after stopping 30 feet back will then commit to the turn from 30 feet back giving drivers little to no time to see cross traffic. If I am the supervisor of fsd who is liable for my safety and my vehicle's safety, I need to be able to see cross traffic before my car (with fsd engaged) decides to commit to the turn, but fsd does not care if the driver can see. The "creep" is perhaps the least human-like manuever that fsd performs. From the stopped location directly at the stop sign, they creep may inch up and stop again, it may inch up a couple times and stop again, it may pull up to the edge of the road and stop again, or it may just pull out into oncoming traffic in one swift motion. Bc of this behavior, fsd has almost got rear ended countless times at stop signs. Also, cross traffic see's the creep and thinks I'm about to pull out in front of them drivers go beyond the stop sign to a location where they can see to make their one and only full stop. To avoid this issue, fsd needs to do this too (I. E. Make initial full stop at the edge of the road) this is legal in mostly every state (I live in PA) Tesla has not provided a single response to these reports and nothing seems to be getting done about it.

The contact owned a 2025 Tesla Model Y. The contact stated that while the vehicle was parked in a school zone area, and while engaging the brake pedal, the vehicle unexpectedly lunged forward with no warning light illuminated. The contact stated that after lifting their foot from the brake pedal, they heard a hissing sound and the vehicle accelerated. The contact attempted to avoid a collision by making a left turn; however, the vehicle traveled into a bushy area and rolled down a hill. The contact sustained injuries, including head, neck, and back injuries, and received medical attention at a local emergency room. The contact stated that the air bags deployed during the incident. A police report was filed. The vehicle was towed and deemed a total loss. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 7,213.

On several occasions, my Tesla Model Y has braked for no reason while using traffic aware cruise control as well as when using autopilot. I can re-create this situation on the same parts of the highway. The sudden, uncommanded stopping creates a hazardous situation with the cars being me as I may get rear ended. At this point, I do not feel safe using autopilot or tacc. I submitted a ticket to Tesla but they declined to work on it.

On 11/29/2025 at 1635 hours, our Tesla Model Y - awd was parked on our driveway with a less than 1% incline after it was snow blowed, cleared of snow. The Tesla was plugged in to its charger. The vehicle then unexpectedly, uncontrolled began moving forward, striking the car in front of it shortly after I walked in front of these Tesla. This incident could have seriously injured myself or one of my children. Tesla said car is operating as designed and was due to cold temps, snow and slight grade of driveway. Video is available from security cameras on house which can be supplied upon request as you system doesn't support the video upload.

When driving on slippery surfaces, if I release the accelerator pedal—even slightly—the vehicle automatically activates regenerative braking to recapture energy. On ice, this sudden deceleration mimics applying the brakes, which can cause an immediate loss of traction and control. This happened to me recently while driving in snowy and icy conditions. As soon as I eased off the accelerator, the car engaged regenerative braking, the wheels lost grip, and the vehicle began to slide, similar to what would happen if hard braking were applied on ice. I momentarily lost control of the car, creating a serious safety hazard. This behavior is not intuitive and can surprise drivers, particularly in winter climates. Unless regenerative braking is manually adjusted or turned off—something not every driver knows to do—the system can unintentionally put the vehicle into a skid. I am requesting that NHTSA review this issue. A software modification or warning may be needed so drivers are not placed at risk due to unexpected regenerative braking on slippery surfaces. Thank you for your attention to this safety concern.
