general problems of the 2023 Tesla Model Y - part 1

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.

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 down a city street near my home and put my Tesla Model Y in full self driving and looked down for 1-2 seconds to retrieve something from my center console and the warning notifications started going off and before I had any time to react, the car drove into a parked car at approximately 39 mph. I have records showing the car was in full self driving for 5 seconds before impact.

On 05/31/2026, while Tesla full self-driving (fsd) was actively engaged, the vehicle was taking the la brea avenue entrance ramp onto the I-10 freeway in los angeles, CA. Fsd suddenly accelerated aggressively and the vehicle drifted hard to the left without any driver steering input. The driver was forced to hit the brakes and manually override steering to prevent a serious accident. The behavior felt like a system glitch. Both driver-side wheels sustained severe impact damage and are confirmed cracked. Tesla service center confirmed the damage in writing on 06/08/2026 and quoted $2,325. 74 in repairs. This dangerous fsd behavior matches the pattern currently under active NHTSA engineering analysis.

On xxx at approximately 12:30–1:00 pm, I was backing my Tesla Model Y out of my garage. While reversing, I felt unusual vibrations coming from the vehicle. After backing out, I shifted the car into drive and attempted to make a left turn. At that point, the vehicle would not turn, and it began producing significant noise and vibration. I exited the vehicle to inspect it for any obvious issues, such as an object lodged underneath the car or a flat tire. I found no visible obstructions, and all four tires appeared to be in good condition. I then drove the vehicle forward toward my driveway and garage area and inspected it again. During this inspection, I found a finger-sized screw or bolt underneath the vehicle. I attempted to reverse the car once more, but the same problem occurred: excessive vibration and an inability to steer either left or right. There were no warning lights, alerts, or notifications displayed on the Tesla screen at any point during this incident. I subsequently contacted Tesla roadside assistance and requested that the vehicle be towed to a Tesla service center. Tesla remotely accessed the vehicle data but informed me that they could not detect any issues based on the vehicle diagnostics. They suggested that I drive the vehicle to the service center. I explained that the vehicle was unable to turn left or right and that I did not believe it was safe to operate under those conditions. At the time of the incident, I was accompanied by my [xxx] father-in-law, and we were preparing to travel to an urgent care facility. The vehicle had been operating normally the previous day. The vehicle currently has approximately 32,077 miles and is approximately 2 years and 5 months old from the date of manufacture. The vehicle has no history of repair work or tire service performed outside of Tesla-authorized service. My primary concern is the significant safety risk presented by this failure on public space. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

While driving, a critical heavy-duty front lower control arm / lateral link bolt completely detached from my vehicle and was found intact on the ground with factory green threadlocker still visible on the threads. The undercarriage and chassis show absolutely zero signs of external impact, scrape, or road hazard damage. This structural failure caused an immediate, severe safety hazard, rendering the vehicle completely unsafe to drive due to a catastrophic risk of wheel separation and total loss of steering control. This exact component failure is identical to Tesla's historical safety recalls, specifically NHTSA recall campaign number 21v835000 and its expansions, which explicitly state: "the front suspension lateral link bolts may not have been secured to the correct specifications. . . Causing the fasteners to loosen over time and separate from the sub-frame. " because the bolt loosened and fell out over time due to insufficient factory torque, the loose component put uneven mechanical stress on the lower control arm, resulting in the complete failure and damage of the control arm assembly. Tesla service center has refused to honor this as a latent manufacturing defect, hiding behind warranty expiration. They have unconscionably misclassified a known, life-threatening production defect as standard "wear and tear," forcing me to pay a $265 diagnostic fee and the full cost of a complete control arm replacement under protest. I am filing this report because Tesla is actively endangering consumers by failing to expand their suspension fastener recall to cover vehicles experiencing the exact same catastrophic manufacturing defect outside the arbitrary warranty period. Nhtsa odi complaint records show multiple substantially similar failures outside Tesla’s recall VIN population, including odi nos. 11630487, 11554803, 11494976, 11493354, 11486040, 11689987, 11675200, and 11632785 for Model Y vehicles, and odi nos. 11720800, 11705487, 11675676, 11664858, 11637813, etc.

While making a normal right turn at low speed in a residential neighborhood, I heard knocking sounds from inside the vehicle and immediately lost steering control. I had to physically force the wheel back into position to regain control of the car. After the initial incident, every right turn and brake application produced a loud rubber grinding sound accompanied by significant loss of steering control. The vehicle was completely unsafe to drive. Tesla previously issued recall sb-22-31-002 for 2023 Model Y vehicles for improperly torqued front lower lateral link fasteners at the factory which are the exact same components that failed on my vehicle. Tesla confirmed my VIN was not included in the recall. The vehicle has been driven normally with no accidents or abuse. Mileage at time of failure was approximately 58,000 miles.

Bolt fell out of the lateral control arm on the front left wheel. Car was inoperable.

On Saturday 16th oct 2026 around 10 am est, while driving down the ramp from parking floor 2 to parking floor 1 in the jfk terminal 4 short term parking garage (john f. Kennedy International airport, new york), the Tesla vehicle suddenly accelerated forward very fast on its own without any input on the accelerator pedal. Either I was not pressing the gas pedal at the time, or I was slowing pressing as the car was going down on ramp. The car surged ahead with significant force and struck a fence at the bottom/end of the ramp area. There were two passengers in the vehicle. No other vehicles were involved. The impact caused: my Tesla Model Y to sustain severe front-end damage and appear to be a total loss. Injuries to both passengers. Minor scratches on my hands. Sequence of events: I was driving the vehicle at low speed down the ramp from parking level 2 to level 1 in jfk terminal 4 short term parking. Without pressing the accelerator, the car unexpectedly accelerated. Braking did not prevent the impact. The vehicle came to a stop only after hitting the fence. Today, I have reported this as a sudden/unintended acceleration event to Tesla and requested a full vehicle data log review. I would like Tesla to investigate following. 1. Why the car suddenly accelerated on very speed? 2. Why the steering got locked when it happened? 3. Since it is the closed parking lot, why Tesla did not stop automatically before hitting fence? I have been driving for more than 27 years, I never had any accident, and I never got any tickets in last 27 years.

On the evening of April 8th 2026, my wife was driving our 2023 Tesla Model Y home in san francisco, CA when she noticed unusual noise coming from the front left wheel area. The vehicle was otherwise functioning normally aside from the noise. The following morning, I inspected the vehicle and found a large hex bolt (class 10. 9 grade) on the ground directly beneath the car. The front left wheel was binding and the vehicle was completely undrivable — the wheel felt stuck and made grinding/scraping noises when attempting to move. Based on the bolt size, grade, and location, this appears to be a front suspension lateral link fastener that detached from the subframe. This is the same defect described in NHTSA recalls 21v-835, 22v-895, and 23v-235, involving under-torqued or improperly secured front suspension fasteners on Tesla Model Y vehicles. The vehicle had 28,482 miles at the time of the incident. There was no prior collision, impact, or road hazard event. No warning or alert appeared on the Tesla touchscreen at any point. The vehicle displayed no diagnostic message despite having a compromised suspension component.

While performing a low-speed reverse turn into a driveway, a loud clunk was heard and the driver side front wheel completely separated from alignment. The vehicle became immediately undrivable. Upon inspection, the ball joint retaining nut was found to be absent from the front driver side suspension assembly. No torque verification mark was present on the fastener. The vehicle is currently at an authorized Tesla service center for repair and is available for inspection. Safety risk: complete loss of wheel alignment and directional control. Failure occurred at low speed in a private driveway. Had this occurred at highway speed the consequences could have been catastrophic. Confirmed by dealer: an authorized Tesla service advisor confirmed that a technical service bulletin exists in Tesla’s system for this exact condition. No owner notification was issued prior to failure. The advisor confirmed the retaining nut is installed by an automated robot assembly process with no human torque verification step and no verification mark applied. Prior warning symptoms: none. No warning lamps, no messages, no audible symptoms prior to catastrophic failure. The absence of a retaining nut on a safety-critical suspension fastener with no quality verification process represents a systemic assembly defect potentially affecting all vehicles produced under the same assembly process.

The bolts attaching the front passenger wheel's lower lateral link to the body fell out. Luckily this occurred while pulling into a parking lot. Once both bolts had fallen out the vehicle was not steerable. There have been many instances of this reported online, but usually they occur with far fewer miles and I was not experiencing the symptoms. The day prior there was an alert stating that an alignment was needed but it was still okay to drive. I could tell there was a slight alignment issue while driving. The vehicle was towed to a Tesla service center and is currently being repaired.

I was parking my vehicle in my driveway, turning left to park in front of my garage and heard a loud pop. I got out, looked underneath the car and didnt see anything unusual. I later investigated by moving the vehicle and noticed my steering wheel was turning without any driver input, and heard the tires scrubbing more than normal. I got out of the vehicle and noticed my tires were not aligned, having one tire pointing to the left, and the other tire pointing straight. Then I noticed a large bolt on the ground. I called Tesla and they told me my car was 2000 miles out of warranty and would have to pay for towing and the repair. I feel the steering should still be covered under warranty.

Catastrophic axle failure, I was driving out from my driveway when this happened. Just the day before my wife was driving on the highway, and I was driving with my two boys. I have video of the complete failure of the left driver's side axle. The vehicle was towed by the dealer and is at the dealer as we speak. There has been no inspection by the police or insurance representative. We had reported it to Tesla at our last appointment but they said they could not recreate the noise.

While driving under normal conditions, without any prior impact, collision, or road hazard, the control arm on my vehicle suddenly detached. This occurred during active driving and caused an immediate loss of vehicle stability and control. The failure happened without warning and posed a serious safety risk. At the time of the incident, my children were in the vehicle, which significantly increased the danger. The vehicle had not been involved in any accident or misuse. This appears to be a potential manufacturing or assembly defect involving a critical suspension component. Tesla towed the vehicle and repaired it at no cost. However, a suspension/control arm failure during normal driving is a serious safety concern that could lead to loss of steering control and possible crash. I am reporting this incident for safety investigation purposes, as this type of failure may pose a broader risk to other drivers.

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.

Nature of defect: while operating full self-driving (fsd) at highway speeds, my vehicle exhibits involuntary lateral swerving — sudden, uncontrolled movement to the left and right without driver input. This behavior occurs repeatedly and unpredictably, posing a direct safety risk to the occupants of my vehicle and to other drivers. Tesla service diagnosed the root cause as a failed fsd computer and recommended full replacement at a cost exceeding $3,000. Crashes or injuries: none to date, though the behavior described above creates a significant risk of collision at highway speeds. Frequency: recurring during fsd engagement at highway speeds. Additional context: this defect was present during my vehicle's original warranty period. Tesla has been aware of this issue since my service visit and has not completed the repair. I have an active goodwill warranty request pending with Tesla that has gone unacknowledged for over two weeks. I am submitting this complaint because I believe this defect may affect other Tesla vehicles equipped with the same fsd hardware, and I want NHTSA to have a record of this failure mode.

On February 23, 2026, I was driving my 2023 Tesla Model Y under normal city conditions. While parallel parking at very low speed, I suddenly heard a loud metallic bang from the driver’s side of the vehicle. Immediately afterward, the vehicle lost mobility and the steering wheel became unresponsive and would not turn. I exited the vehicle and observed a detached metal suspension component and a bolt on the ground underneath the driver’s side. The vehicle was not drivable and required towing. I contacted Tesla roadside assistance through the Tesla app, and the vehicle was towed to Tesla service center in coral gables, florida. At the time of the incident, there had been no collision, no impact with a pothole, curb, or road debris, and no prior warning signs or noises indicating a developing issue. The failure occurred suddenly during a low-speed maneuver. Tesla service initially indicated that the vehicle was under warranty and that repairs would be covered if no external impact was found. However, after inspection, Tesla attributed the failure to an alleged “external impact” and declined warranty coverage, providing an estimate of approximately $4,000. After involving my insurance company, the vehicle was inspected by a Tesla-certified repair facility, which found significantly more extensive damage to the suspension system, estimating repairs at approximately $11,000. This incident represents a sudden and complete failure of suspension components resulting in immediate loss of steering control. Such a failure poses a serious safety risk, particularly if it were to occur at higher speeds, as it could lead to loss of vehicle control and a crash. I am reporting this issue as a potential safety defect involving suspension component separation and steering loss in a 2023 Tesla Model Y.

Like many have mentioned, the control arm bolt came off or broke. [xxx] / [xxx] / [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On January 29, 2026 my 2023 Tesla Model Y was serviced by Tesla for windshield repair and routine maintenance. Within a week after the service visit, the vehicle began displaying a service warning message on the dashboard. I contacted Tesla and was advised to bring the vehicle back for inspection. Before I could return to the service center, while slowly reversing out of my garage, a large bolt fell from the vehicle and the front left wheel assembly dropped, causing the vehicle to come to an abrupt stop. Tesla service later confirmed that a bolt from the front suspension link assembly had detached, resulting in damage to the front halfshaft, steering gear, wheel speed sensor, and other related components. The vehicle had approximately 38,000 miles at the time of failure. This appears to be a critical suspension hardware failure. If this failure had occurred at highway speed it could have resulted in loss of vehicle control and a serious accident. The vehicle had been serviced by Tesla shortly before the incident and had displayed a warning message prior to the failure.

While making a left turn at normal turning speed, the steering system became unresponsive. The steering wheel was able to move; however, there was no corresponding movement of the front tires/wheels. The front wheels appeared to remain stuck at approximately a 45-degree left position and did not return toward the straight-ahead position despite steering input. It is also possible that the steering wheel itself became locked or partially locked during this event. As a result, the vehicle could not be corrected and collided with the median and a pillar. The collision caused the airbags to deploy and resulted in severe front-end damage, with an estimated repair cost exceeding $40,000. This steering failure occurred without warning and resulted in a sudden loss of vehicle control, creating a serious safety hazard to the occupants and surrounding traffic. The vehicle was subsequently declared a total loss.

While traveling at highway speeds, the vehicle suddenly veered to the right without driver input. The autopilot/fsd system was not engaged. It all happened in a matter of seconds. There was no system failure message on the screen. The vehicle airborne and hit a tree. All side airbag were deployed. Was able to open the door and walk away without any major injuries. Software update : 2025. 44. 25. 5.

I was driving on the highway at around 70mph, switched lanes and the steering wheel randomly locked up. Gladly, I was aware of the situation and avoided a huge car crash but the steering started to work a few seconds later. I am very nervous to drive the car now.

All in the same day: 1) odd sound from behind the pedal area of driver side front quarter (sounded like a styrofoam cooler top rubbing against the cooler is the best way to describe - faint though). 2)bang when in a parking garage turning full right but still able to control without difficulty. Made it home without incident. 3)later that day, just after getting off of i4 in orlando I pulled into grocery parking lot and parked. When I returned to my car I again turned right and a loud bang and the car jerked to a sudden halt. I was able to back into a parking spot but there were 2 large screws in the driving land and the left wheel was toed slightly to the left. Ultimately it was detached when we tried to tow it we had to remove tire and put on a device to allow us to move it. Per Tesla “I have updated that estimate! the vehicle has very heavy damage, and this is the start. Once we replace these components their (sic) could be more damage, and it also could potentially need to go to a body shop!” thankfully this didn’t happen at speed with my daughter in the car on i4! this is unsafe and a simple internet search revealed it is not an uncommon parts failure at this mileage! this is dangerous. All of this at just 54,000 miles. (4k out of warranty).

A critical front suspension component failed on my 2023 Tesla Model Y without any accident, misuse, or external damage. While backing out of my garage at low speed, a loud “bam” occurred — the front lateral link bolt fell off, detaching the lateral link and causing the front body to drop onto the tire. My child was inside the vehicle. Tesla-certified technicians inspected the vehicle and service records confirm the lateral link bolt was loose and missing, directly causing the failure. Multiple suspension components were replaced under warranty, confirming a manufacturing defect, not customer-caused damage. This is a serious safety-critical failure. At driving or highway speed, it could have caused loss of steering, severe injury, or death. The day before, my spouse drove the vehicle on the highway with our younger child — by luck, a catastrophic event did not occur. Before and after the wheel detached, the Tesla monitor did not display any warnings. Even after the lateral link and wheel partially detached, the vehicle remained in driving mode and ready to operate, despite a wheel being unsecured — a basic condition that should trigger an immediate alert. This demonstrates a critical failure in Tesla’s safety systems. There were no recalls listed under my VIN. However, NHTSA records show similar failures, with recall notifications issued under NHTSA recall 21v-835 in 2021 for 2021 and earlier Tesla Model Y and model 3 vehicles. The same failure in my 2023 Model Y at 23,641 miles shows the defect was not fully corrected and continues to pose a public safety risk. I am reporting this to NHTSA due to the extreme safety risk and request a full investigation.

While driving approximately 5–10 mph and making a right turn on a local street, the vehicle suddenly produced a metallic pulling sound followed by a loud impact. The vehicle abruptly stopped and became undrivable. Upon exiting the vehicle, the left front wheel was visibly displaced from normal alignment and appeared to have shifted rearward into the wheel well. No collision, curb strike, pothole, or road debris was involved. The vehicle had exhibited a wire-tugging or metallic noise during turning in the days prior. The failure occurred without warning and resulted in a sudden loss of vehicle control at low speed. The vehicle was towed to Tesla, where the left front control arm was found to be disconnected/broken. Tesla has not yet provided a determination and is attempting to route the vehicle to a collision center despite no evidence of impact. This appears to be a suspension component failure that could have resulted in a serious accident at higher speeds. Safety impact: loss of steering control, risk of crash, inability to drive vehicle.

My Model Y experienced a sudden steering assist failure while driving. The wheel became extremely stiff/locked even though autosteer was off. Multiple thermal system faults appeared: vcright_a271_thssensorfault, vcright_a257_thsmia, gtw_w043_thsversionmismatch, and hvacsystemnotnominal this was very scary as I was driving and had no control of steering wheel because it locked.

Currently on the newest Tesla full self driving software v14. 1. 4, it is phantom breaking as well as phantom swearing out of nowhere. It is swerving and using the breaks so hard it actually affects the steering wheel and self disengages it's self (without the big-loud safety alert to immediately take over control), it just does the soft disengage audio notification, like if you wanted to cancel fsd yourself. The serious problem is that the car does not stop like it should, instead it just continues it seems like it just neutrally rolls on its own drive and twice in the last week it would swerve directly into oncoming traffic. It is not supposed to be doing this at all, especially now that the "hands off" approval is enacted. I drive about 450 miles a week and this has happened about twice a week for the last two weeks. Thank god I was paying attention all four times, but I am so worried this is going to kill someone. I have tried to call Tesla but they purposely don't staff their phones and no one answers.

I am writing to file a complaint regarding a safety issue with my 2023 Model Y performance Tesla vehicle. The steering wheel's faux leather covering is peeling and bubbling, causing the material to come off while driving. This poses a significant hazard as it compromises my grip and creates a distraction, potentially leading to loss of control. Additionally, Tesla does not want to repair this, even though I’m still under warranty.

While driving home from a shop, my Tesla Model Y suddenly stopped in middle of busy road and became unable to move forward. I had to press the accelerator hard, which caused a loud noise before the car moved slightly and I was able to pull over to side of road. I narrowly avoided being hit by another car. Upon inspection, it was found that front tire connecting rod and suspension had failed, causing rod to drop off. The tow truck who assisted me mentioned that this is common issue with Tesla vehicle. This was a terrifying experience and I feel extremely fortunate to have escape an accident. My vehicle is less than 24 months old and I am deeply concerned about the safety and reliability of this component . I strongly urge Tesla to issue a recall and investigate this defect. There is no assurance that this failure won’t happen again. And this is scary.

The bolt that holds the front lateral link portion the the lower control arm to the subframe fell out while driving. I lost the ability to steer the car and had to stop immediately and have the car towed. In searching the internet this is a know issue by Tesla but has not been recalled.

During normal driving on sat Sep 27 2025, unusual noises started to come from the front left wheel. There were no warning lamps or messages, and no indication of issues prior to onset of the noise. I had the vehicle towed to a Tesla service center the following day. Tesla's technicians found that the front lateral link bolt on the left hand side had backed out and fallen out of the subframe. They determined that the cause was related to improper torque specification or application of the original bolt. They reached this conclusion in part because the passenger side lateral link to subframe bolts were also under-torqued. Rear bolts were not affected. Tesla has replaced the front lateral links on both sides with new bolts. There was no vehicle accident or damage, so there has been no involvement or inspection by police or insurance. It is fortunate that this issue began when the vehicle was traveling at low speed, and that I chose to have the vehicle towed to the service center rather than driving it. The bolt has loosened when the noise started, and finally fell out at the service center. Had I been driving at highway speeds when the bolt fell out, I could have lost control of the car and injured myself and others. Online research suggests this is not an isolated incident for this model of car.

I picked up my son from school and got home at about 3:30 pm on Sunday 9/21/2025. My son got out of the car and I heard a “clicking” sound when turning my steering wheel to the left to prepare for backing into my garage. There were no warning lights or messages for this issue. I did get out of my car and checked, but did not see anything that hit my car underneath. I got back in my car and continued backing my car into the garage. The nightmare started happening - the bolts connecting the front control arm and steering knuckle fell off that caused the left “arm” disconnected from the steering knuckle. This had resulted a sudden total loss of steering control. Please see attached photos. I could not imagine if this would have happened on the freeway.

Two days ago a warning popped up on the Tesla screen saying to schedule service for something the car had detected. It said the car could still be driven. I submitted a service request in the app, and in the meantime researched the error. Per google, it said this was a potential issue with suspension / steering components that needed to be looked at. The next day, a Tesla technician called and asked what my appointment was for. I told him about the error and that I had found it said it was for a suspension or steering issue. He told me I was wrong, and that it was only for low tire pressure. The car did not have low tire pressure. He said the appointment wasn't needed, cancelled the appointment, and told me to drive 30-40 miles to clear the error. Literally 5 hours later, after my wife driving my kids down the freeway, when parking on the street in front go my house the car made a giant pop and the front left sank. We looked under the car and the front drivers side control arm had completely disconnected, popping straight down towards the road. More concerning, two bolts popped out, not broken, but just clearly loose and had finally unscrewed. You will see them on the ground in the pictures. If this had happened 5 minutes earlier while on the freeway I don't want to even think about what might have happened. These cars should be recalled, this is super dangerous. Not to mention the fact that Tesla explicitly canceled my appointment for this and told me not to bring the car in.
