Severe defect: unprompted autonomous steering overrides manual driving. When autopilot is off, emergency lane departure avoidance (elda) violently yanks the steering wheel, steering toward hazards like oncoming traffic on the left or a mountain/rock wall past the curb on the right. This creates a severe collision risk, overriding safe manual input. Documented proof: provided Tesla service (palo alto) over 12 timestamps and several dashcam footage. Technicians physically verified no internal/external camera obstructions across two separate visits. Moving a transponder failed to resolve it. Tesla refusal: service center has canceled two other service requests without fixing the defect, claiming it the 'system is working as intended. ' crucially, the manager jay explicitly admitted this dangerous steering override is a 'known issue for vehicles without fsd' operating on an older, separate software stack prone to these errors. To resolve this critical safety hazard, he explicitly suggested I purchase Tesla's premium full self-driving (fsd) upgrade, claiming the fsd stack fixes it. Tesla is fully aware their base active safety software stack is defective and steers into hazards, yet demands a paid consumer upgrade to resolve it rather than issuing a safety patch or recall.

Subject: safety hazard caused by emergency lane departure avoidance on [2026 Tesla Model Y] description: I am writing to report a serious safety issue regarding the emergency lane departure avoidance (elda) feature on my us-spec Tesla. Starting with recent software updates, the vehicle forces the lane departure avoidance setting back to "assist" upon every single drive cycle, with no option to disable it permanently. This behavior creates an immediate safety hazard, especially in cold climate regions and during winter driving conditions. When attempting to steer around immediate road hazards such as open manholes, deep potholes, or debris, the vehicle's cameras fail to recognize the object in the road. If the driver maneuvers to avoid the hazard without a pre-activated turn signal, the elda system aggressively intervenes, jerking the steering wheel back into the path of the danger. On slippery, icy, or wet roads, this unexpected electronic intervention causes a sudden loss of traction, risking a severe crash. Forcing a driver to navigate multiple sub-menus on a touchscreen to change a safety-critical setting before every single drive is dangerous and distracting. In the united states, there is no federal mandate requiring this setting to reset to "assist" on every drive. I request that NHTSA investigate this aggressive software behavior and compel Tesla to restore the option for owners to permanently set lane departure avoidance to "warning" or "off".

On 8/22/2026, my 2022 Tesla Model Y long range with approximately 81,000 miles developed an electronic power assisted steering (epas) fault immediately after I felt a brief jerk while reversing. The vehicle displayed “steering assist reduced / steering may require increased effort. ” manual steering currently feels normal, but full self-driving/autosteer and lane departure/lane keeping functions became unavailable. Tesla service mode shows repeated faults epas3p_a072_motfeedfwderror, epas3p_a049_pictrlerror, and ui_a020_steeringreduced. For epas3p_a072, Tesla’s diagnostic screen describes a “motor control feed-forward correlation error,” lists the potential impact as “reduced steering assist and eac inhibited,” and specifically lists “replace epas” as the clear condition. The faults return after vehicle power-off and reboot. The vehicle was updated to software 2026. 21. 6 / fsd v14 lite approximately two weeks before this occurred. There were no previous steering warnings. I am not claiming the update caused the failure, but I believe the timing warrants investigation. Nhtsa complaint 11749826 describes a 2021 Model Y with the same epas3p_a072 and ui_a020 faults, including Tesla service mode stating “replace epas. ” complaint 11758026 describes another 2021 Model Y steering gear failure and requests expansion of recall 25v-092 to earlier Model Ys. My vehicle has not yet been physically inspected by Tesla. The vehicle and diagnostic information are available for inspection. I request NHTSA investigate whether this epas failure extends beyond the current recall population and whether recent software changes may be contributing.

Component failed: electronic power steering (epas) system / steering rack. The vehicle is currently displaying the active safety alert code: ui_a020 ("steering assist reduced / disabled"). The vehicle is available for inspection. Safety risk: a sudden loss of primary power steering assist creates a severe safety hazard, requiring extreme physical effort to steer the vehicle. This increases the risk of a crash during sudden maneuvers or at low speeds. Confirmation & warning lamps: the ui_a020 warning message is actively displayed on the vehicle's touchscreen. Tesla service has remotely acknowledged the alert code and required a diagnostic fee approval via the mobile app. Inspection status: the vehicle has not yet been physically inspected. Due to severe service backlogs, the earliest available appointment Tesla could provide is more than a month away, on September 30th. I am forced to either park the vehicle or drive it with a known, I think there's active steering system fault until that date.

Safety defect report: unmapped recall expansion / component commonality my 2021 Tesla Model Y experienced a sudden, dangerous loss of electronic power-assisted steering (epas) while driving, instantly displaying the alert: "steering assist reduced / steering may require increased effort. "an official diagnosis by Tesla service (estimate #3000-009-0038060635, attached) confirmed a catastrophic failure of the steering gear assembly, requiring a full replacement of the unit. The specific component listed for replacement is steering gear - left hand drive, part number: 1188832-00-b. This is the identical engineering architecture and part family (1188832) targeted in NHTSA safety recall 25v092 for an overvoltage breakdown of the internal epas printed circuit board. While my vehicle falls outside the current 2023 Model Year production window defined by Tesla for 25v092, it uses the exact same component architecture and suffered the exact same failure mode. This represents a clear pattern of failure and component commonality expanding into earlier Model Years (2021). I am submitting my official itemized Tesla repair estimate of $3,072. 50 as physical documentation. I request that the NHTSA review this component match and investigate an expansion of recall 25v092 to protect other owners of earlier Model Years from this sudden loss of steering control.

The contact owns a 2023 Tesla Model Y. The contact stated that while the vehicle was in self-driving mode and driving approximately 5-8 mph, the vehicle suddenly turned towards the left into oncoming traffic. The contact immediately manually started steering the vehicle. The contact stated that there was an abnormal popping and snapping sound coming from the steering wheel. The vehicle eventually came to a stop, and the contact became aware that the steering wheel was bent inward. The vehicle was towed to the dealer, who was unable to diagnose the failure. The vehicle had not been repaired. The manufacturer was not made aware of the issue. The failure mileage was 10,500.

The contact owns a 2023 Tesla Model Y. The contact stated that while driving at an undisclosed speed, the vehicle became difficult to maneuver and independently veered into the other lane. No warning lights were illuminated. The vehicle was taken back to the residence. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 42,335.

Failed component & availability: 2023 Tesla Model Y front suspension (suspected lower lateral link detachment), steering system, and airbag system (failed to deploy). Preserved intact, but will be at hendrick collision ([xxx]; poc: dendi [xxx]) under allstate claim #xxx. Available for immediate NHTSA inspection. Safety risk: at highway speed on aviation parkway, the car suffered an unprompted, violent directional loss, zig-zagging uncontrollably in the lane and risking a multi-vehicle crash. Operating manually. Do not have autopilot or fsd. I was at the mercy of the vehicle's sensor/chassis failure. The car crashed into the grass median, sustaining heavy driver-side damage. Airbags failed to deploy during impact. Confirmation by repair center: physical teardown is on hold pending event data recorder (edr) "black box" imaging and chassis alignment inspection. Inspections to date: allstate level 1 claim #xxx assigned. Evidence preservation and cloud telemetry extraction notices served to Tesla legal and allstate. Warnings & prior repair history: no warnings appeared immediately prior to steering failure. Software was fully updated. This crash occurred 14 days after a 2nd high-voltage (hv) battery replacement: xxx: hv battery error code -> 1st hv battery replacement (returned xxx) xxx: recurring hv battery error -> 2nd hv battery replacement (returned xxx) xxx: unprompted directional failure and crash. Investigative context: matches NHTSA pe26006 investigating 2021-2023 Model Y front lower lateral link detachments causing sudden loss of control. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

A front bar on the lower front left of the car collapsed leaving 2 screws on the groung and steerling wheel not usable.

I own a 2021 Tesla Model Y with an hw3 car computer. At approximately 54,000 miles, the vehicle developed intermittent failures of the cameras, gps/navigation, and cruise control. On two occasions during the same routine drive, about 40 minutes into the trip, the gps, cameras, and cruise control abruptly stopped functioning at approximately the same location. The first occurrence was about July 7, 2026 at 9:15 am and the second August 7, 2026 at about 3:15 pm. I made the same trip once between these events without a failure. I had also previously experienced a frightening incident while driving northbound on I-280 approaching the lane division for 19th avenue in san francisco using autopilot. Where my lane widened and a new lane began, the vehicle abruptly attempted to follow the new lane to the right. I had to intervene firmly with the steering wheel to maintain control. I do not know whether this event was related to the later diagnosed computer failure, but report it because of its possible safety significance. Tesla serviced the vehicle in sunnyvale on August 16, 2026 at 54,565 miles. Tesla's invoice states: “technician addressed the intermittent loss of gps, cameras, and cruise control. The car computer had board-side failures and was replaced. ” Tesla replaced the hw3 computer with a hardware 3. 2 computer, part 1775000-s0-l. Tesla also found corrosion at the 12v input and replaced the 12v battery. My concern is that the hw3 computer failure was intermittent and simultaneously affected cameras, gps/navigation, and cruise control. The vehicle operated normally between failures, so a driver could not know when the problem might recur. I ask NHTSA to determine whether similar hw3 computer failures are occurring in other 2021 Model Y vehicles.

On August 3, 2026, my Tesla Model Y was traveling at approximately 50 mph with Tesla full self-driving (fsd) engaged. At approximately 4:12:47 pm cdt, fsd became unavailable and then became available again. At 4:12:51. 628 pm cdt, fsd was recorded as active_fsd again. Approximately 2. 36 seconds after fsd was re-engaged, at 4:12:53. 987 pm cdt, the vehicle's steering began a sudden and rapid rightward movement. I did not turn the steering wheel or intentionally provide a rightward steering input that initiated this maneuver. The recorded steering angle increased rapidly from approximately +11. 4° to +20. 7°, +33. 3°, +83. 3°, +137. 9°, +154. 7°, and ultimately approximately +282° within about 1. 6 seconds. Importantly, fsd was still recorded as active_fsd when the steering movement began. Fsd changed to unavailable at approximately 4:12:54. 364 pm cdt, about 0. 38 seconds after the steering movement had already started. The steering continued to escalate after fsd became unavailable. The vehicle subsequently experienced severe lateral acceleration of approximately 0. 96 g, and crash detection activated at approximately 4:12:55. 710 pm cdt. The accelerator was recorded at 0% during the developing steering event and increased only after crash detection. Hard braking and abs activation occurred afterward. I do not have Tesla dashcam footage, but I have retained Tesla's vehicle telemetry export containing fsd state, steering, steering-torque, accelerator, braking, vehicle-speed, stability-control, and crash-event data. I am concerned that Tesla fsd may have initiated or contributed to the unexpected steering maneuver that resulted in the collision. I am certain that I did not initiate the sudden rightward steering maneuver. I request that NHTSA investigate whether this represents a potential safety defect or unexpected fsd behavior, particularly the sequence of fsd re-engagement followed approximately 2. 36 seconds later by the unexpected steering event while fsd was still active_fsd.

I was driving the car inside the parking garage of the ucla medical plaza in westwood at around 3:10pm on xxx, looking for an appropriate parking spot. When entering the second basement floor and turning the steering wheel right, to follow the road, the steering wheel was unresponsive and the car felt as if in neutral gear. As the car was on a downward slope, it went straight into the car parked in front. It happened so fast, but it seemed as if the brakes were ineffective. The air bags on the sides were deployed. On the front, the airbag in the steering wheel came out but did not inflate. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

This issue occurred on August 02, 2026 at around 3pm. I was parked and put my 2023 Tesla Model Y in reverse to give myself enough room to drive forward from being parked on road next to my house. While going into reverse, I heard a really loud bang noise coming from under the front section of the car. I put the car in park and got out to take a look around. At first I thought I had hit something while backing out but did not see any object in the reverse camera. So then I kneeled down and looked under the car and that's when I saw the passenger side front lateral arm of the suspension detached and left hanging down from the wheel. I let Tesla know what occurred using their app to message the company.

Vehicle can become difficult to steer in certain situations.

The contact owns a 2021 Tesla Model Y. The contact stated that while the vehicle was parked, there was an abnormal sound while turning the steering wheel to the left or the right. There was no warning light illuminated. The vehicle was taken to an independent mechanic, and the contact was informed that the lower and upper control arms were failing. The contact was informed that the lower and upper control arms needed to be replaced. The contact was advised to take the vehicle to the dealer. The dealer was made aware of the failure. The contact stated that a service appointment was scheduled. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 100,000.

While operating my 2022 Tesla Model Y, the vehicle suffered a catastrophic hardware failure of the onboard vehicle control computer. This total computer failure resulted in an immediate, sudden loss of electronic power steering assist while the vehicle was in motion. The steering wheel became incredibly stiff and heavy, creating a severe and hazarders driving situation. The vehicle was towed to a Tesla service center, where technicians confirmed the onboard computer hardware requires a complete replacement. A vital computer failing prematurely on a 2022 vehicle presents an extreme safety risk of crash or injury due to sudden loss of vehicle control.

On 7/22/2026 between 6pm and 7pm pst, I was driving my Tesla Model Y on I-405 southbound in orange county, CA, between the westminster blvd exit and exit 73, with full self-driving (supervised) engaged. The incident occurred at an express lane ingress/egress transition zone where a physical barrier separates the express and general-purpose lanes. While in fsd mode, the vehicle initiated a lane change on its own. During the lane change, the fsd system misjudged the lane boundary and steered the vehicle into the lane divider/barrier. The vehicle struck the divider on the front right side. The failed system is the fsd/automated steering and lane change function. No forward collision warning sounded and no automatic emergency braking activated before impact with the fixed barrier. There were no warning lamps, alerts, or symptoms prior to the failure; the system initiated and executed the lane change without indicating any problem. The impact damaged the front right body panel, front right bumper area, and the right headlight. My safety and the safety of vehicles in adjacent lanes was put at risk, as the collision occurred at roadway speed during an automated maneuver I did not initiate. Had the divider been a vehicle or a pedestrian work zone, the outcome could have been far more severe. All fsd telemetry, camera footage, and vehicle data from the incident should be available from the manufacturer, and I have requested the vehicle data report from Tesla. The vehicle is available for inspection upon request and is being taken to a Tesla-certified collision center for repair. An insurance claim is being filed with my carrier. The vehicle has not yet been inspected by the manufacturer or police.

I was backing out of my residential driveway when I suddenly noticed the steering wheel required much greater effort than normal, indicating a loss of power steering. There were no prior warning messages or symptoms before this event. As I began driving, multiple warnings appeared on the display, including “steering assist reduced,” “stability control disabled,” “traction control disabled,” and “vehicle hold unavailable. ” the steering immediately became extremely heavy, making the vehicle difficult to maneuver safely. Because the failure occurred without warning, I did not feel it was safe to continue driving except to move the vehicle as necessary. The vehicle was subsequently inspected by a Tesla service center, which confirmed that the steering rack and front vehicle controller required replacement. The repair was performed by Tesla after diagnosis. I am submitting this report because a sudden loss of steering assist without any prior warning presents a significant safety risk. Although this occurred while pulling out of my driveway, the same failure could occur while a driver is traveling at higher speeds or in traffic, where maintaining control of the vehicle could be much more difficult.

Tesla took off from a parking lot and was uncontrollable, went through the grass, crossed the street and construction before hitting the barricades and fell into a sewer as the road ended there. There were 2 passengers in the car and luckily both passengers came unharmed. But fsd needs to be investigated on why this happened.

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.

While driving straight ahead in my lane on a wet freeway in an active construction zone, the vehicle abruptly and without warning lost traction and spun out of control. I was traveling in a normal, controlled manner with the flow of traffic and was not turning, braking hard, or making any abrupt maneuver when the loss of control occurred. It was so sudden that I initially believed another vehicle had struck me. I was unable to recover control, and the vehicle left its lane and was involved in a collision that resulted in the vehicle being declared a total loss. This is a nearly new all-wheel-drive vehicle, approximately 17 months old, equipped with electronic stability and traction control. I am an experienced driver with a clean record and had driven this same vehicle through mountain roads the week prior without any issue. A vehicle of this type is not expected to suddenly lose control while traveling straight. The specific component or system that failed is unknown. No warning lamps or messages appeared before the loss of control. The vehicle data available to me as an owner is limited and does not reflect the full diagnostic logs the manufacturer retains. The vehicle is a total loss but is preserved and available for inspection upon request. The manufacturer has not inspected or responded. A police report was filed.

On 07/16/2026, I was driving my 2023 Tesla Model Y when the vehicle suddenly began swerving rapidly left and right across multiple lanes without my intended steering input. The vehicle became difficult to control, and despite my attempt to correct the direction, it continued to move unpredictably and resulted in a collision. There were no prior warnings or indications of a steering or control issue before the incident. After the collision, I reviewed the Tesla usb drive and found that dashcam and sentry mode recordings from immediately before and during the incident were not available; only recordings after the incident were present. I am concerned that a possible steering, electronic control, or software malfunction may have contributed to the loss of vehicle control.

This is what happened: while full self-driving (fsd) was engaged, the vehicle approached an intersection and appeared unable to correctly follow the roadway. Instead of following the intended road path, the vehicle continued forward, drove over the curb, and struck a road sign. The impact knocked the sign down, and the sign subsequently struck the vehicle, including the roof glass. The roof glass shattered and small pieces of glass entered the cabin, exposing both the driver and front passenger to a safety risk. Vehicle data obtained after the incident shows that the vehicle was in active_fsd leading up to the collision. Fsd changed from active to unavailable approximately 1. 5 seconds before the crash algorithm wake-up. Significant braking occurred only very close to the collision, and no automatic emergency braking intervention was recorded during the incident window. The data also shows multiple substantial steering movements shortly before the collision. Accelerator-pedal data does not establish driver acceleration as the cause of the collision. The available samples show an accelerator position of 2. 0% shortly before the collision and 0. 0% in the next recorded sample. The driver applied the brake shortly before impact. There were no prior warning lamps or messages indicating that fsd was about to become unavailable before the vehicle departed the roadway. The vehicle has been inspected/repaired following the collision, and vehicle data relating to the incident has been obtained and preserved. Police responded to the collision, and the incident was also reported to insurance. A police report was filed, and the case number is 2026-07160174. I have not yet received the formal cr-4 crash report. Following the collision, I experienced significant psychological distress and trauma-related stress symptoms as a result of the incident.

Vehicle safety complaint on xxx, between approximately 9:45 pm and 9:52 pm, we were driving our Tesla Model Y eastbound on [xxx] and exited at [xxx] toward [xxx]. As my husband was making a left turn after exiting the freeway, the steering wheel suddenly became stuck or extremely difficult to turn. There was no warning, no unusual driver input, and no use of autopilot or full self-driving. The vehicle does not have full self-driving capability. My husband had to use significant force to regain steering control to avoid striking the left side of the roadway/median. Because the vehicle did not respond as expected, the car behind us nearly rear-ended us. Our two children, ages [xxx] and [xxx], were properly restrained in the back seat. Fortunately, no collision or injuries occurred, but the incident could easily have resulted in a serious crash. This incident raises significant concerns about the safety and reliability of the steering system. I am requesting that this complaint be investigated and that Tesla review the vehicle’s logs from the time of the incident. The vehicle has also been reported to Tesla for inspection. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Safety defect report: sudden power loss & falsified records 1. Incident & 5-hr towing (xxx): on xxx at ~16:30, while executing a low-speed (<10 mph) left turn in cambridge, MA, the vehicle had a sudden, total high-voltage failure mid-turn, losing all motive power and power steering without warning or error codes. Photos/videos were taken on-scene confirming zero physical impact or undercarriage collision. The dead vehicle stopped directly in the active lane, completely blocking traffic. With zero power, the driver and several helpful bystanders had to use extreme physical effort to manually push the dead car out of the road. Aaa arrived at 18:00 but could not tow because total power loss completely locked all 4 wheels/brakes (no tow mode). Aaa dispatched a 2nd specialized flatbed with dollies (arrived 21:00). Driver was stranded on-site for over 5 hours. Car reached Tesla dedham service at 22:00. On xxx at 10:00 am, driver reported the driving power loss in person at dedham, handed over key, and got a loaner. 2. Written notice (xxx): on xxx, explicit written notice was sent to Tesla service manager taso, re-confirming the exact mid-driving power loss hazard. 3. Tesla diagnosis & repairs: invoice #xxx confirms a severe high-voltage failure: "a hardware overcurrent event caused small high voltage battery brick imbalance and rear inverter failure. " Tesla replaced rear drive unit inverter (3du) and pyrotechnic battery disconnect (pyrofuse). 4. Falsification of safety issue: despite 5-hr towing from wheel lock-up, xxx in-person report, and xxx written notice detailing mid-turn power loss, Tesla falsely recorded on invoice: "customer states: vehicle will not charge. " this is deliberate falsification and deceptive practice by Tesla to downplay a critical road hazard into a benign charging issue. I request NHTSA to investigate this high-voltage overcurrent/inverter failure pattern and Tesla's practice of altering safe information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Car making excessive noise, service department refuses to address at Tesla even though various cases of the same issue are easily available online. Issue is with half shaft lubrication being dried but Tesla is trying to charge and claiming that the part hasn’t failed. But to me a part failing due to lack of lubrication can lead to hazard road conditions. I don’t want to put my kids safety in harm but Tesla tells me that no lubrication will not result in part failure.

The electronic power assisted steering (epas) rack on my 2021 Tesla Model Y experienced an internal electronic failure. The failure first occurred while the vehicle was performing an automated parking maneuver (autopark) at low speed. The vehicle displayed the warning "steering assist reduced / steering may require increased effort" (alert ui_a020_steeringreduced). Using the vehicle's built-in service mode, I retrieved the underlying diagnostic fault: epas3p_a072_motfeedfwderror, described by the vehicle as "motor control feed-forward correlation error," set when the difference between estimated motor torque and commanded torque exceeds 1. 2 nm. The vehicle's own diagnostic screen lists the clear condition for this fault as "replace epas," indicating an internal hardware failure of the primary epas module. The listed potential impact is "reduced steering assist and eac inhibited. " the fault initially cleared after approximately three minutes but returned and is now latched: it persists through vehicle reboots and multiple drive cycles. While the fault is active, power steering assist is reduced and lane keeping assistance / active safety steering features are inoperative. Safety risk: steering assist can degrade without warning during low-speed maneuvers, requiring sudden and substantially increased steering effort, and lane keeping assistance is disabled. The failure occurred while an automated driving feature was in control of the steering, with no curb impact, collision, or abnormal use.

Power steering is giving difficulty while driving on the highway, stiffens up and hardens and makes it difficult to steer to the left or the right. Took it to the dealer, they confirmed needed a new steering rack, checked online quite some people with the same issue especially with their cars coming from the same year. No warning lamps doesn’t show up on the screen, took to Tesla dealership and they ran a diagnostics and then confirmed.

Error ui_a020 "steering assist reduced" appears without any noticeable steering changes at the moment, but with a warning that steering may become increasingly harder and harder. There were recent recalls on other models of Tesla.

Unintended violent steering intervention at highway speeds causing an immediate safety hazard. Almost caused a fatality pulling the car off the highway nearly hitting light posts and highway sign.

I was driving the vehicle and heard a lot crack and felt the steering wheel unstable. Whenever I would turn the steering wheel the car would make crackling noises and I would feel the car go up as I was driving. When I was turning into my driveway the car felt like the whole left wheel had fallen off, according to my spouse she said the wheel looked like it was folding in as a turn and the car was elevating. We made an appointment with Tesla service senter and we had to get our car towed since it was not drivable. I went to speak with the Tesla agent and they had told me there was wear and tear on both lower front arm links and that they had replaced them. My car has only 19,000 miles so that seemed extremely strange and fast. The following day as I was cleaning my driveway I noticed a big suspension bolt on the ground, I took a picture of the bolt and sent it to my agent and he confirmed it was form the suspension bolt. Something they never mentioned until I found the bolt in my driveway. They repaired the issue according to them, we had no messages or indications of something going on. We also noticed that our wheels were getting worn down unevenly due to this. This is a family vehicle which is concerning that we could’ve had a more serious accident if it would’ve happened at a highway or on a trip.

While driving my 2026 Tesla Model Y in June 2026, the vehicle suddenly applied steering input on its own and began swerving left and right even though there were no obstacles in the road. I was driving on a straight section of roadway, centered in my lane, when the steering wheel started moving by itself as if the lane keeping system and steering were confused. I had to fight the wheel in both directions to keep the car from veering toward the curb and toward the adjacent lane. It felt like struggling against another person at the wheel. Fortunately there were no vehicles directly beside me at that moment, so I was able to avoid a collision, but this behavior could easily cause an accident for a typical driver. This incident is part of an ongoing pattern of safety issues with this vehicle. Since late 2025, I have experienced multiple events where the car fails to respond to the accelerator after shifting into drive and behaves as if it is in neutral until I shift back to park and then into drive again including a complete loss of propulsion while driving in moderate traffic. Tesla has already performed recall repairs on the battery/battery contactors and multiple diagnostic visits for intermittent loss of propulsion and steering concerns, but the problems continue. I am filing this complaint because I believe there is a serious defect involving the steering, propulsion system, and lane keeping driver assist systems that could cause loss of control and a crash.

Steering wheel vibration occurs at highway speeds between 70 and 75 mph on a 2026 Model Y with under 1,000 miles at time of complaint. The vibration was reported to the dealer, who performed a tire balance and alignment check and confirmed both were within specification. The vehicle was tested by the dealer during a service ride-along and no vibration was detected by the technician. However, vibration was independently confirmed by the owner in a same-model loaner vehicle on the same road, suggesting the issue may not be isolated to a single vehicle or tire set. Similar vibration issues have been reported by other owners of the same Model Year in online owner forums, with no documented fix currently available. Safety concern: reduced steering feedback at highway speeds. The vehicle remains available for inspection upon request.
