Tesla Model S grinding brakes problems

Filed Oct 26, 2026 · Suspension, Wheels · FL

On October 25, 2026, I was slowly pulling out of a residential parking space in my 2015 Tesla Model S, which has approximately 82,500 miles. Suddenly, I heard a very loud grinding noise, and the vehicle came to an immediate stop. Afterward, the car would not move either forward or backward. I had not hit any potholes, curbs, or other obstacles. There was no collision or external impact. When I inspected the vehicle, I noticed that the left rear wheel was severely tilted and misaligned. The vehicle became completely undrivable. Based on the visible damage, I suspect a serious failure involving the left rear suspension or wheel assembly. However, the exact component that failed and the cause of the failure have not yet been determined. The vehicle has not yet undergone a mechanical inspection. I have photographs documenting the condition of the rear wheel and suspension area. I am very concerned about the safety implications of this sudden failure. Had this occurred at highway speed, it could have resulted in a serious accident. I contacted Tesla regarding the incident. I am reporting this failure to the federal safety agency as a potential vehicle safety defect and requesting that it be reviewed for similar incidents involving the 2015 Tesla Model S.

The contact owns a 2016 Tesla Model S. The contact stated that approximately six days after purchasing the vehicle, while driving approximately 45 MPH, the vehicle drove over a bump in the road, and a grinding sound was heard coming from the vehicle. The contact stated that after driving over a bump in the road, the vehicle felt different while driving. The vehicle was taken to an independent mechanic, who reportedly observed significant corrosion and rust affecting the suspension system and advised the contact that all suspension components needed to be replaced. The independent mechanic advised the contact not to drive the vehicle due to safety concerns and indicated there might be structural damage to the vehicle. The contact stated that after the suggestion, the contact continued operating the vehicle. The following day, the vehicle was taken to the dealer where the vehicle was purchased, and the contact was advised that the failure was associated with worn brake pads. The dealer replaced the brake pads. The contact believed that additional repairs may have been performed but was not advised of any other work completed. The vehicle had not been modified and had not been inspected by Tesla. The contact believed that the vehicle may have an inaccurate odometer reading; however, no evidence was available to support the concern. The contact remained concerned that the corrosion and possible structural damage might exist within the suspension system even though the brake pad was replaced. The failure mileage was approximately 108,000.

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 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.

Front suspension has a popping and creaking sound when driving and turning steering wheel. Safety issue as sounds something is loose but Tesla says no issue it’s the body flexing which is even scarier to hear the panels rattling if this is in fact true. Tesla will not do anything about it. Additionally the brakes and rotors squeal when pressed at slow speeds coming to full hard stop. Both front and back. Both brakes and rotors have 90% life and according to Tesla shouldn’t need replacing until 90k miles due to the regen braking. The braking system does not engage as it should or how it is designed and car has 40k miles. Tesla uses the excuse that that they don’t cover this as it’s a wear and tear component. Which another issue because they don’t know the reason of why it’s doing this. They want customers to pay and replace the brakes and rotors. Many owners with same car experience this issue and is a design defect that can pose safety issues

This is the 3rd time a control arm on the car has cracked. I see tons of people online complaining about the same issue with the fault aluminum control arms. I have no damage and no rust and it just cracked on its on as i was backing out of a parking spot. I could have been seriously injured or my daughter had this happened on the highway. My dad is an issurance adjuster for 30 years and has never heard of any cars control arms cracking on their own. Please help as this is a huge safety issue and it seems Tesla has been putting the blame on the drivers. There was a grinding noise in reverse and the wheel was tilted inward. Multiple control arms have cracked in the car. A car that has no damage or accidents. This car is less than 10 years old and this doesn't happen with any other cars. It's a fault control arm part made out of cheap aluminum.

Front air suspension failed while driving on the highway at 70 MPH while traveling from El P Paso, Texas to Albuquerque, New Mexico in July on 2023. front end of the car hit the ground and could not steer without tire grinding into the wheel well. Upon getting the car inspected for the problem, it was found that the front left air suspension had malfunctioned and because of the way the air suspension works, neither right or left side of the suspension would hold air and keep front of the car off the road. Cost of repairs was $1258.95 which Tesla refused to admit there was a design flaw that would render the car undrivable.

As I was backing up out of a parking spot, I was turning the wheel when I heard a pop and a ugly grinding noise coming from my front driver side wheel well. Initially, I thought I ran over something, but did not observe and debris under the vehicle. I proceeded to slowly pull forward and continued to hear grinding, but not as bad. When I turned, the grinding continued. I got out again to observe that my wheel had caught the back half of my wheel well cover and ripped it off, sitting in the wheel well still. A firm tug pulled the cover from the well and I could see the wheel was not situated in the center of the wheel well. After contacting the manufacturer, they towed the vehicle and I learned that the control arm had snapped and they would need to replace the whole front suspension. They also noted a couple knicks under my carriage and very minor scrapes on my bumper and said that the failure was due to outside influence and, thus, would not be covered by my active warranty. They said I was in an accident which is completely false. After research, I presented numerous instances of control arm failure for the same year/model as my car at very low mileages, including recall for the same parts in China, but they still refused to cover the faulty part. There is an open class action lawsuit for the exact same parts because the manufacturer refuses to acknowledge the problem. I had to pay to upgrade the suspension system which they now use in the car as they obviously don't use the old faulty components when repairing. If this failure was at full speed on the freeway, I might have lost control of the vehicle and been killed and nobody would be the wiser after the disastrous accident. As there is only a recall in China for this part, I am forced to pursue legal action through court to recover the costs.

Tesla Model S began making clunking/grinding noise when reversing out of a driveway with the wheel fully turned. It turned out that the front left and right fore links have failed prematurely and caused the front wheels to rub on the wheel arch/fender. No potholes were ever hit to cause the damage. Car needed replacement parts totaling $979. A wheel alignment was also needed. Car only has 97,000 miles.

While pulling out of a parking space at less than 5 mph the front left suspension fore link broke, resulting in damage to the wheel liner. The left front wheel could be described as loose or wobbly and resting at less than 1 cm from the rear side of the wheel liner, making turning nearly impossible. If this had happened at a higher speed it could have been catastrophic. There was no warning measures on the vehicle but a series of unusual metal grinding noises could be heard immediately after the break. The vehicle was placed on a flatbed and towed to the local Tesla, Inc. repair location where it was inspected and repaired. All 4 front lower fore links were replaced both on the left and right side for a total cost of approximately $2000.
