Tesla Model X grinding brakes problems

Filed Sep 16, 2026 · Transmission · CA

The car was making a grinding and knocking sound which varied with the engine speed. This noise was confirmed to be coming from the rear drive unit by the Tesla technician. The vehicle has approximately 105,000 miles. An internet search revealed it was a common problem. The repair costed $6,502.20. It appears the problem was related to the original part which had a high failure rate and this was corrected with an updated part (ASY, DRIVE, UNIT, 3.0-150, REAR (1037000-00-F)). I understand this the drive unit that would address the coolant-ingress/seal failure of the Model X Large Drive Unit

I own a 2016 Tesla Model X P100D 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 the federal safety agency open an investigation and require Tesla to issue a recall for free repairs/replacements on all affected 2012–2020 LDU vehicles.

My 2023 Tesla Model X Plaid's falcon wing doors have had a persistent rattling/squeaking defect since August 2023 that has not been resolved after 9+ repair visits to Tesla service centers. More critically, in November 2025 (Invoice #3000S0014846906), the left falcon door's ultrasonic sensor failed to detect an adjacent vehicle's side mirrors, causing the falcon door to strike and scratch the other vehicle's mirrors — a safety incident for which I was forced to pay out-of-pocket. Tesla replaced the ultrasonic sensor under warranty but did not compensate me for the third-party damage. Additionally, in January 2026, the right falcon door was showing a "press and hold to override" error approximately 20% of the time despite no obstacles being present, requiring replacement of the sensor carrier (Invoice #3000S0015725078). The door sensor failures represent a serious safety hazard as the falcon wing doors can strike pedestrians, cyclists, other vehicles, and property. These issues have not been permanently resolved despite repeated warranty repairs spanning nearly 3 years.

Making a loud squeaky noise and knocking while I turn. The noise is coming from the steering and front suspension arms I believe.

Control arm squeaks. Only way Tesla fixes is to replace. Smoke fix is a 2$ grease application to ball joint but they charge 1500$. I have done it 2 times and now again happened.

The steering wheel is hard to turn while driving. Also, heard a clanking/ squeaking sound while driving.

The contact owns a 2020 Tesla Model X. The contact stated while depressing the accelerator pedal, the vehicle was making an abnormal sound. The contact stated there was a grinding and whining sound coming from the vehicle while driving approximately 30 MPH and the sound was constant. There was no warning light illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the front-end half-shaft needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 46,000.

Steering Stuck: It happened several times that the steering wheel completely locked up while driving on the road. Today it happened again. It does not move, cannot turn left or right. I was in the middle of the road, the only thing I could do was to back up. I had to stop in the middle of the road and reboot the car. Luckily the cars behind me were able to stop before crashing into me. In May 2024, I addressed the same issues, but it happened again. I think it is their defect which I have serious concerns for my safety. I heard other people also experienced the same as mine. I believe this is the defect which will cause the danger of drivers. Suspension and tires: I went to several tires shops every year and they all told me that my tires have been worn quickly because alignment was not properly installed. I went to Tesla, but they said there were no issues. The fact is that my tires have been worn quickly than normal and we can hear the squeaky noise from the suspensions when turning. My friend has the same issues with his tesla. This is also a defect that Tesla needs to repair it. WiFi: My Tesla cannot connect to WiFi for all of those years for updates. I have asked Tesla to help but they cannot connect to it either. This is a defect that they cannot fix which cause my car not being able to update it automatically.

Problem #1: The Components that failed are the front wheel fenders, they blew off while driving down the highway, they have since been repaired. the repairman said that these blow off all the time due to how they are installed with plastic clips and glue. My families safety was put at risk because the moment that this happened the sensor was showing something that was about to hit us. had the auto drive been enabled at this time the car could have taken measures to avoid what it thought was an object. We were also put at risk as well as others driving behind us by the parts blowing off onto a highway while driving at high speeds. The component was inspected by the service tech that worked for Tesla. I took the car into Tesla to have the car serviced before driving to California, they cleared the car and said that everything looked great, no warnings or symptoms. Problem #2: On the same drive to California, we had a error that showed as "Safety Restraint System Fault". This error seems to come and go so it may be available upon request depending on the day it is. The safety of my children are put at risk because we will not know when they are taking off their seatbelt due to this error. The Error has been inspected by Tesla on multiple occasions and they cannot seem to find how to fix this. I have another appointment with them on [XXX] to try again to fix it. There is a Warning, but it is very vague and does not let you know where the problem is. Problem #3: Tesla's Front Suspension Arms lose all Grease and start to make a grinding noise while going over minor bumps. This puts people at risk because at any moment the cars suspension could fail while driving due to the ware on the suspension. The component has been inspected by Tesla and they said that I should wait until the other arm starts to fail to replace them both at the same time. No warnings or anything has been shown due to this. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Squeaking noise on the passenger rear side was noticeable when I am hitting the breaks then a thump sound as if I landed on some big pothole occurred. So I drove as slow as I can until we reach home. I inspected the vehicle and to my surprise the control arm had torn and the tires were hanging loose.
