Power Train Problems of Tesla Model S - part 1

I own three 2016 Tesla vehicles with the same known safety defect: two Model S p100d and one model x p100d, all equipped with the large drive unit (ldu). The component that fails is the rotor coolant seal in the rear drive unit motor. Coolant leaks internally into the motor and inverter, causing bearing wear, corrosion, isolation faults, and eventual complete drive unit failure. The affected drive units are still installed and available for inspection upon request. This defect puts my safety and the safety of others at risk because it can cause sudden loss of propulsion (especially at highway speeds), power reduction, or total drivetrain shutdown, potentially leading to a crash. Coolant in high-voltage areas also raises electrical fault/fire risks. The problem is widely reproduced and confirmed: Tesla service centers are familiar with it and replace failed units with updated “-u” revisions that include a coolant bypass. Independent ev shops confirm the exact root cause (rotor seal failure) via encoder inspections showing coolant intrusion and through disassembly. This is a documented pattern failure in all 2012–2020 ldu vehicles. No police or insurance inspections have occurred yet, as no crash or total failure has happened. Tesla is aware of the recurring issue through service records on similar vehicles. Early symptoms before full failure typically include rear motor whining/grinding (especially under load), reduced power warnings, “rear drive unit fault” messages, and visible coolant on the speed sensor. These can appear gradually. My vehicles have not yet experienced total failure, but the defect is known to be inevitable. I am proactively monitoring encoder sensors. Because this is a systemic design defect affecting thousands of vehicles with clear safety implications, I request NHTSA open an investigation and require Tesla to issue a recall for free repairs/replacements on all affected 2012–2020 ldu vehicles.

**incident / defect description for NHTSA safety complaint** **vehicle information** - make: Tesla - model: Model S - year: 2014 - VIN: [xxx] - approximate mileage: 148,129 miles - date of discovery / failure: 04/23/2026 **description of the defect** this vehicle is equipped with Tesla’s large drive unit (ldu / rear drive unit), which was used in the majority of 2012–early 2020 Model S vehicles (rwd and performance models). The ldu design routes coolant through the hollow rotor shaft. Over time, the rotor seal fails and allows ethylene glycol coolant to leak internally into the motor and inverter. Evidence of this failure is easily visible by removing the rear speed sensor, where blue coolant, corrosion, and debris are present. This is a well-documented design flaw affecting thousands of vehicles. **consequences of the defect** coolant intrusion causes: • corrosion and rust in the stator windings • washing out of bearing grease • high-voltage isolation faults • inverter damage • complete drive unit failure **safety risks** this defect presents an unreasonable risk to motor vehicle safety because: • drive unit failure can occur suddenly and without warning while driving, resulting in total loss of propulsion. This is especially dangerous on highways, in traffic, or at high speeds. • coolant inside high-voltage electrical components increases the risk of electrical shorts, arcing, or fire. • reduced power or complete shutdown can lead to loss of vehicle control and potential crashes. I have experienced complete drive unit failure. Many other owners report identical issues, often between 50,000–120,000 miles. Tesla has not issued a recall despite this being a widespread, predictable design defect. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The rear large drive unit (ldu) has coolant intrusion due to a known design defect in the internal rotor seal. Coolant from the stator cooling system is leaking past the seal into the motor, degrading the winding insulation. An independent inspection by the electrified garage (orlando, FL) on 04/08/2026 confirmed moisture at the rotor sensor (yellow condition) and degraded insulation resistance measured at 3. 0 megohms (should be hundreds of megohms on a healthy unit). The vehicle requires a complete drive unit replacement at an estimated cost of $7,000. This is a well-documented design defect affecting 2012-2016 Model S vehicles. Tesla has acknowledged the issue by redesigning the seals in later production units and performing "coolant deletes" on remanufactured replacement units, but has not issued a recall or extended warranty coverage. The vehicle currently has 53,542 miles and no prior drivetrain warnings, yet the drive unit is failing due to a manufacturing/design defect, not owner abuse or normal wear.

I am reporting a safety-related defect involving sudden loss of motive power on my 2016 Tesla Model S. During the drivetrain warranty period, the vehicle developed a persistent humming/buzzing noise from the rear drive unit. This noise was documented on video with a timestamp confirming it occurred while the vehicle was under warranty. At the time, there was no loss of performance or warning indicators. Due to the distance to the nearest Tesla service center (approximately 200 miles), the vehicle was not immediately inspected. When I later contacted Tesla service, the vehicle was approximately three weeks outside the drivetrain warranty. Upon inspection, Tesla advised that the rear drive unit was failing and would require replacement at customer expense. Tesla declined warranty coverage despite evidence that the failure symptoms began during the warranty period. The rear drive unit later catastrophically failed while the vehicle was being driven uphill, resulting in a complete loss of propulsion. Prior to this incident, Tesla service personnel had advised that if the rear motor failed, the front motor would allow the vehicle to operate in a limp mode to reach a safe location. This did not occur. When the failure happened, the vehicle lost all motive power and was unable to maintain position on an incline. The vehicle nearly rolled backward into traffic. Police assistance was required (911 call) to redirect traffic so the vehicle could be rolled backward down the hill to a safe location. A minor child was present in the vehicle at the time. I am aware that failures of rear drive units on 2016–2017 Tesla Model S vehicles related to coolant intrusion have been reported by Tesla service personnel and other owners. This incident demonstrates a serious safety risk involving sudden loss of power and incorrect guidance regarding vehicle behavior during drive unit failure. I believe this represents a safety-related defect warranting investigation.

The power train of my 2025 Model S failed similar to failure of 7-6-25 which I previously reported to NHTSA (complaint #11718413) and Tesla. Upon getting into my car on 2-7-26 and putting it in reverse, several alert messages displayed including "stability control disabled, traction control disabled, and emergency braking unavailable". I drove 1/4 mile to a safe area to call Tesla roadside assist, since my steering was noticeably degraded in real time and the car was not safe to drive. The car was towed to the nearest Tesla service center. Tesla made statements on their service report attached here, that this is a "known characteristic of the vehicle" and that if it happens again I should, "exit the car, let the car go to sleep and then once the vehicle is awakened the alert will not be present and it will operate normally". That is not a valid solution, and even though they told me they found nothing wrong when they looked at the car two days later on 2-9-26, I had walked away from the car for more than an hour on 2-7-26 when this happened and the alerts were still there. The tow truck driver who arrived three hours later also saw them and noticed the degraded steering when he drove it. Tesla's solution stated on their service report is not valid or safe. This issue has happened twice in seven months on this car of mine and it needs serious engineering attention.

While driving in traffic, the vehicle displayed warnings stating “unable to drive — pull over safely. ” the vehicle progressively lost power and became unable to propel itself, requiring me to stop in traffic. Additional warnings indicated reduced acceleration and performance. The vehicle remained powered (screens and electronics active) but could no longer drive. Tesla later diagnosed a high-voltage battery failure and provided an estimate for full battery replacement. The sudden loss of propulsion in traffic created a safety hazard because the vehicle could not accelerate or continue moving with traffic.

This is a supplemental filing to my prior NHTSA complaint (#11697718) regarding a high-voltage isolation fault and shutdown risk. The vehicle displayed warnings including “vehicle may shut down during driving,” “may not charge,” and repeated bms isolation fault messages. It became inoperable at a public charging station. The manufacturer confirmed isolation faults in the drive unit and the a/c compressor. Their own service notes stated that the vehicle “may shut down during regular driving” and that charging “may not be safe. ” despite this, the vehicle was left at 0% state of charge for an extended period and then charged by the manufacturer. They later stated to a regulator that the vehicle was “trickle charged at 1 amp for 6 hours,” but the vehicle’s range increased by approximately 100 miles, which is not physically possible at that charging current (1 amp at 240v for 6 hours = 1. 44 kwh ? 4–5 miles). This discrepancy suggests the vehicle may have been charged at a higher rate than claimed and without proper cooling, despite the documented a/c failure that is necessary for battery thermal management. Battery condition is unknown because the manufacturer refused to perform or provide a battery health analysis, isolation resistance values, thermal logs, or charging session data. The safety defect could not be verified as repaired. While this safety issue remained unresolved, the manufacturer rejected a Tesla roadside tow arranged under regulator instruction to second service center and instead arranged an unauthorized tow to remove the vehicle from their facility without my consent. The vehicle was taken to a non-manufacturer storage lot while still in an unsafe state. I am concerned about: • high-voltage isolation faults, • shutdown risk during driving, • unsafe charging performed by the manufacturer, • possible battery damage from low soc and charging without a/c cooling, and • mishandling of an active safety defect. The vehicle is available for inspection.

This is an update to NHTSA complaint #xxx with new safety information. My 2017 Tesla Model S (VIN [xxx] ) has a confirmed high-voltage isolation fault. Tesla replaced the rear drive unit under warranty, but Tesla’s own technician notes now state: “there is a risk of isolation alerts reoccurring during regular driving, use of hvac system, or DC charging. ” “vehicle may power off due to isolation faults when the air conditioning is used. ” this is Tesla acknowledging in writing that the vehicle may shut off during normal driving, even after repair. This presents a serious crash risk. The original failure occurred during supercharging, with warnings including: • “electrical system power reduced — vehicle may shut down unexpectedly” • “vehicle may not restart” • “air conditioning reduced — DC charging reduced” Tesla reproduced the isolation fault during diagnosis. Even after replacing the rear drive unit, Tesla documented that the isolation defect still exists and prevents a battery health check or DC fast-charge validation. Tesla has attempted to return the vehicle to me in this unsafe condition, while admitting the defect persists. They also stated they may charge storage fees or tow the vehicle, despite the unresolved safety issue. The defect affects the hv bus and can cause loss of propulsion, shutdown during driving, and charging failure. Tesla has not provided numeric test results (megohm isolation readings, insulation tests, or validation data) proving the vehicle is safe. This is an ongoing, manufacturer-confirmed hv isolation defect that can lead to sudden power loss. I request NHTSA review Tesla’s handling of this issue and link this filing to case #xxx. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

7/30/2025 the vehicle experienced a confirmed total loss of function to include steering, restraint, and braking functionality at approximately 60 to 65 miles per hour. This catastrophic failure placed myself and and others at severe risk. Although Tesla’s service notes confirm the event occurred, no corrective repair was performed. The vehicle was completely inoperative with a matter of seconds with no prior warning. At this point in time the car has continued to not operate the same steering and noises has been in the shop 5 times still no answer or repairs in regard to it shutting down or any other issues that continue to return. The last visit I was asked to purchase new tires because maybe that’s why, I did. I continue to be told nothing is wrong with the vehicle making me feel extremely defeated when I know the vehicle is not the same as it was.

The power train of my 2025 Tesla Model S failed. As a result, the car had several systems alert on my console that they were "unavailable" or "degraded", and in addition to the alerts I experienced their loss or degradation in real time. This included braking, steering, stability control, and traction control. Normally you don't have to hold the brake pedal down at a stop light on this electric vehicle, but when the failure occurred my car was rolling backwards at the stop light and so I had to hold down the brake. Also, steering was noticeably degraded and not stable. The car was also exhibiting behavior similar to a stuck accelerator whereby even with my foot off the accelerator the car would not slow up. Tesla had to tow my car to their nearest Tesla service center, and they replaced the front body controller and the battery controller which took three days. There were no warnings whatsoever or anything relating to the power train that were peculiar prior to this incident. It occurred all of a sudden after getting into my car and putting it in reverse to back out of a parking spot. I was then bombarded with several alert messages as mentioned above and drove only about half a mile until I pulled into a parking lot and called Tesla for roadside assistance as the car was obviously not safe to drive.

This is very comment of Tesla not responding to customer about the power reduced in the car is safe concerns is lot of people with the same problem and Tesla want pay for all the repairs of the car even with my car still warranty.

I wanted to bring a situation to your attention, report an incident and understand why model years 2012-2020 Tesla Model Ss have not been recalled for a defective drive unit. This is a known defect - known by Tesla. There have been no recalls for mine - VIN number [xxx] . On [xxx], my 2016 Tesla Model S suddenly lunged and jerked down to less than 5 mph from about 45 mph in 5-10 seconds as a result of a defective and failed drive unit, here in san ramon , CA. No warning. We forced the car to lunge and hop over to the median with traffic stopping, building up, honking, braking. . . . Truly a miracle no one got hurt. I later saw both front and back wheels turning in opposite directions, simultaneously, as the tow truck driver was pulling the car on his flat bed. The tow truck driver said he has never seen anything like this! the defective drive unit has been a known issue which they corrected in 2020. A master Tesla mechanic states that this is not about if the failure was to take place, but when it was going to take place. Tesla refuses to own up to the problem despite emailing their head, tom zhu. I came across this conversation on reddit and it appears that a comment made by the Tesla mechanic below is relevant. They could have prevented this by recalling the cars and changing the coolant seal. Here is his quote: "every single large Tesla drive unit will fail unless it's a recent revision u replacement (~2022 or newer) or has been retrofitted by a 3rd party. This applies to all rwd Model S made between 2012 and 2020, and all performance s/x made until 2020. The coolant seal will fail and destroy the motor. This is not an if, but a when. If you have a car with one of these motors, there are a variety of 3rd party shops who can fix this issue forever for a lot less money than a fully dead motor. An attorney on this thread commented on a 2015 Tesla Model S: "this is a known issue with older Model S/x cars, yes. A 2015 is highly at risk of that. Also, a information redacted pursuant to the freedom of information.

Coolant ingress found on second Model S large drive unit in rear. After this leak destroyed my first vehicle, second was checked as a precaution and was found to have coolant leaking into drive unit as well.

Large drive unit that has previously been replaced by Tesla failed due to coolant ingress leaking through rotor seal. Known issue per 3rd party technicians.

The contact owns a 2013 Tesla Model S. The contact stated that while driving 30 mph and depressing the accelerator pedal, the vehicle failed to respond as needed. The contact stated that the message "take to service" was displayed. The local dealer was contacted, and the vehicle was towed to the dealer by Tesla insurance to be diagnosed. The contact was informed that the drive unit was rusted and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure via email and a letter. The approximate failure mileage was 150,000.

The rotor seal on the large drive units on Tesla Model S and x fail, causing coolant to leak into the drive unit, flooding it and damaging the inverter. This leads to a replacement cost from Tesla for approximately $7 - $8,000. As this is a design failure this should be a recall and Tesla should at least repair all units prior to their failure or replace them with an updated motor.

My Tesla Model S 2022 unexpectedly shut down while parked in a covered garage on [xxx], after I had driven for an hour. This occurred after I returned from a family trip to lima, peru, where I did not use the car. Tesla service center diagnosed it as water damage requiring a $20,578. 50 battery pack replacement, which was covered by my insurance. There were no warning signs prior to failure. Within 20 minutes of the tow truck dropping off my car at Tesla, a representative informed me it was water damage, citing a system error and claiming over 20 vehicles had the same issue. This suggests a widespread problem and Tesla's awareness of it. This incident raises serious safety concerns about a potential design flaw and the lack of a water intrusion warning system. If this occurred while driving, it could lead to a sudden loss of power and an accident. I urge the NHTSA - investigate if a design flaw exists in the Model S 2022. - investigate Tesla's awareness of this issue and their failure to implement a warning system. - require Tesla, and all ev manufacturers, to submit water mitigation plans. - mandate water intrusion detection and warning systems in all evs. This incident highlights a critical safety risk for Tesla - and perhaps all ev - drivers, and I urge the NHTSA to take immediate action. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The component that Tesla has stated is the part that is failing is the mcu (media control unit) which was a recalled part at one point but then Tesla decided to replace only a single part of the mcu which was the emmc (embedded multimedia card). Luckily the vehicle was not driving when it completely shut down and would not start back up but I was stuck in a restaurants drive-thru for roughly 4 hours till I could get a tow truck to come tow it. The tow truck had to put the car on dollies as the vehicle would not enter tow mode nor would it enter its emergency neutral mode so the vehicle could be moved. The windows would not go up or down and luckily the trunk was able to open because if not then I would have been stuck outside my vehicle as the door handles did not come out after I got out of it and closed the door behind me. Please read the messages from the tech as you will see that they tried to act as if they did not know what was going on with my vehicle but then I asked something else and they stated exactly what the issue was but supposedly could not confirm it was that unless they charged me a diagnosis fee and "got hands on" which I'm sure that info of what was wrong with my vehicle was nothing they needed to get their hands on. There were no warning lamps or messages until the vehicle shut off on me in the drive-thru and then the warnings started to populate staying that the vehicle was off, vehicle could not detect brake being pressed, and that the vehicle was not detecting the key. The repair estimate is no longer available in my app for some reason, probably because I did not repair the vehicle as they were wanting me to upgrade to the new mcu that is in the current vehicles and it would have been roughly $2,400. 00. Just today, the vehicle would not start, would not move my seat or anything to its memorized position when I got in the vehicle and the screen was frozen, just as it did when the original recall happened of the mcu/emmc, photo/videoattached.

My 2014 p85d Model S electric rear motor failed. I heard a loud noise coming from it so I took it in to Tesla and they agreed the motor was failing and needed to be replaced, cost $6,582. 04. If I had driven the car and the motor seized up it while on the highway it would have been catastrophic. I would have lost control as the motor froze the rear wheel. Tesla knows of this problem, has replaced many of them, unfortunately post warranty. They know the seals leak and coolant leaks into the motor and causes the motor to fail. They have made a number of design changes including the latest where they eliminate a cooling branch going through the motor. Prior to this change none of the fixes have eliminated the problem.

The vehicle is over reporting it's speed by 5% this is a large discrepancy which effects safety by causing people drivers around you to change lanes because you are traveling under the speed limit. Tesla is unable to calibrate the speedometers are the service center. They have documented the failure. It also adds miles to the odometer prematurely. This problem started after Tesla upgraded the car with a track package which is a $24,000 upgrade.

The contact owns a 2016 Tesla Model S. The contact stated that while driving at 25 mph and coming up on a fork in the road, though the autopilot system was not activated, the vehicle suddenly veered to the right on its own, requiring the contact to quickly redirect the vehicle towards her intended route. Later, during a separate incident while driving at an undisclosed speed, the vehicle inadvertently lost all motive and electrical power. The contact was able to coast to the shoulder of the roadway, where the vehicle was able to restart. The contact also stated that she had previously become aware that there was condensation building inside the instrument panel as well as the center display and that the dealer had been notified but failed to address her concern. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure, insisting that the autopilot system was likely activated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

Driving my car and it completely gives out in the middle of traffic without any warning or alter almost causing an accident. When asked about the absence of alert they said I may or may not get one and I should be lucky it just cut off (randomly in traffic mind you) because if it didn’t it would’ve burst into flames. Being the rear drive unit is the second most important part of the vehicle an alert should be given 100% of the time as no alert could cause injury to myself or other drivers. This means there are other Tesla drivers out there with a probable chance of their randomly car stopping without any control of the vehicle endangering lives. This oddly happens 60 days outside my 8 year warranty when I haven’t any issues at all and receive alerts for everything down to my fob key being low on battery. In addition the whole time they were just trying to convince to get a new one because they just happen to be running a limited time promo that I can transfer my free supercharging to a new vehicle if I purchased. A lot of people have reported (down to the day) of their car dying suddenly after warranty but no avail Tesla says they won’t goodwill repair my vehicle although I could’ve died or been seriously injured.

Driving the vehicle and all of a sudden all these warning lights came on. The dash flashed warning signs stating: "power reduced - exiting and entering the vehicle may restore operation" "high voltage battery requires service - acceleration and charging performance reduced" and a turtle sign appeared. The vehicle was almost inoperable moving at 1-2 mph. Pulled into a parking lot, parked the car, and exited the vehicle. After reentering the vehicle the error continued. Had the vehicle towed to the Tesla service center. It is currently being diagnosed. An online search showed many Tesla forums with similar issues and there were suggestions to report the incident because there no consistent resolution that has been provided by Tesla thus far - issues range from 2020 - 2023.

I am writing to express my serious concerns regarding two critical component failures in my 2013 Tesla Model S within the past 12 months, both of which occurred shortly after the manufacturer's warranty had expired. These issues have not only been financially burdensome but also raise questions about the reliability and longevity of Tesla vehicles. Motor replacement: in sept 2022, I was compelled to replace the motor in my Tesla Model S at a cost of $6,304. 89. This occurred despite my vehicle maintaining a clean record and having only around 70k miles on it at the time. The timing of this failure, immediately after the expiration of the manufacturer's warranty, is concerning and suggests a potential design or manufacturing flaw. Battery replacement: most recently, I have been informed that the battery in my Tesla Model S requires replacement at an estimated cost of $15,545. 97. Like the motor failure, this comes as a substantial financial burden, and again, it has happened just after the warranty period has ended. I find these consecutive, high-cost component failures within a short timeframe to be unacceptable and have led me to question the overall reliability of Tesla vehicles. As a responsible and safety-conscious consumer, I believe it is vital to report these issues to the NHTSA to ensure the safety and protection of all Tesla owners and the general public. I respectfully request that the NHTSA investigates these repeated component failures in Tesla vehicles, particularly the motor and battery, and assesses whether there may be any systemic issues that warrant further action or recalls. It is crucial for the NHTSA to uphold and enforce safety standards in the automotive industry to prevent similar situations from occurring in the future. I have attached relevant documents and receipts as evidence of the mentioned repairs for your reference. -michael d. Roberts.

Bought the car used. Had issues with rear drive unit that was replaced under warranty. Similar issue before warranty expired and was checked out by Tesla and noted to be " normal" noise. Later the nose got louder and repeat diagnostic recommended rdu to be replaced at a cost of nearly $8500. I believe that the rdu on older models were defective.

Sept 9th, 2023 while driving on the interstate the vehicle lost all propulsion power, red lights shown in "gear, p n d" indicator area. I was in left lane and had to get to the side of the road, 4 lanes over, where putting the car in park and back in drive allowed for it to move forward again. I proceeded to a charging station to inspect the car and during this I hear a thump in the trunk area when going over bumps. Upon inspection under the car the rear access cover was hanging down but it was dark. The following morning a closer look revealed the rear subframe where the engine mounts had broken and a large piece of the frame was missing from the inside down. Mounting tab and hardware were still in place but pulled from the structure itself. The car was not handling correctly as if it had a low tire but tire pressure was correct. At drop off I noticed the rear camber seemed quite cambered. As a structural engineer I can see where the mounting tab weld to the aluminum frame failed. The frame appears to be cast and extruded tubing welded together and the failure is what would be considered a weak point at a weld. Car is currently at Tesla norfolk virginia for an evaluation and when I showed them the issue the staff did not want to document the issue and requested I perform a drive along with a tech. I asked why as the pics were evidence enough as to my complaint and issue. Cursory investigation online yielded this is not an isolated occurrence and with others having very serious failures I felt it important that perhaps it is severe enough for a modified part replacement. For reference no crash damage or any other like issues have occurred prior with the car.

The contact owns a 2017 Tesla Model S. The contact stated while approaching a stop light, while the contact was pressing on the brake pedal to slow down the vehicle accelerated on its own causing the contact to struck the vehicle in front. The contact stated that no warning light illuminated, and the brake assist did not activate. The contact stated when the vehicle struck the vehicle in front the vehicle continued driving forward and then the vehicle was able to come to a completely stop. The vehicle had front ended damages and the other vehicle had rear ended damages. No one was injured. The air bags deployed. A police report was not filed. The vehicle was towed to a repair shop. The vehicle was not diagnosed. The manufacturer was contacted and did not provide any assistance. The failure mileage was 54,000.

Front axle half shafts have failed two times requiring replacement (on 3rd set now). During acceleration the steering wheel vibrates violently. Tesla service center diagnosed both times that front half shafts needed to be replaced. There seems to be some design or manufacturing problem - these items keep failing. The cost to fix is ~$1,650 so I delayed as long as possible until vibration became unbarable. First replacement was done under warranty, second replacement was required ~16,000 later and I was forced to pay for it. There is a Tesla service bulletin about this which I saw online.

Power reduced error. Tesla do not even know how to fix this issue and it seems to be apparent in many of their cars. Please see here: https://teslamotorsclub. Com/tmc/threads/“power-reduced”-warning-and-turtle-icon. 229299/page-2.

The Model S, which was bought in 2015, had a sudden acceleration while I was trying to park near the entrance gate of the parking lot. The accident happened on may 25, 2023. Fortunately, nobody got hurt and the car was totaled. I feel strongly that this should be investigated, as this can be a very serious public safety issue. It was inspected by the insurance company. There were no warning messages prior to the failure.

In June of 2020 I reported a "wobble" noise coming from the front of the vehicle under normal acceleration. I took it to a Tesla repair shop, where the tech confirmed that they were aware of the issue, but Tesla was working on a fix for it and they would contact me when a solution was available. The issue was repaired in sept of 2021, which happened without me initiating it as I had taken my vehicle in for another maintenance issue and re-reported the noise, and they replaced the "half-shaft"s on the front of the vehicle. Now, about 19 months later, the sound has returned and the repair has failed. I contacted Tesla and they advised that I am now out of warranty and thus will have to bear the entirety of the cost associated with the repair.

I have the plaid version… and this care wears out the rear ties within 12-14 thousand miles. . Which is super fast and you can’t tell because it’s the inside of the tire. The metal shoes and is potentially dangerous and life threatening.
