Catastrophic structural failure of the rear driver-side (lh) brake caliper assembly on a 2023 Tesla Model S plaid at approximately 18,036 miles. While driving normally on a public roadway, the factory-installed rear lh brake caliper bolts backed out completely due to improper assembly torque or a latent material defect. The unbolted caliper detached entirely from its mounting bracket and collapsed into the spinning wheel barrel. The caliper became violently wedged between the wheel rim and the rotor, instantly puncturing the wheel, flattening the driver-side rear tire, damaging the passenger-side (rh) rear tire, and causing an immediate loss of vehicle control. The loose caliper acted as an unconstrained projectile inside the wheel assembly, severing the hydraulic brake line, shredding the electronic parking brake harness, destroying the suspension links (rear lower fore/aft links), and destroying the abs sensor/module. This failure created an extreme, life-threatening hazard of a sudden high-speed wheel lockup and total brake system failure. An independent pre-purchase inspection (ppi) was completed just 263 miles prior to this incident. The certified inspector completed an 85-mile test drive and verified the braking and suspension systems were operating in normal factory condition with zero abnormal vibrations or loose hardware. This establishes the failure as a sudden, latent assembly torque failure of factory hardware during normal operational stress. The manufacturer's authorized service center confirmed via technician notes that the caliper came entirely loose and lodged into the wheel. Despite this being a severe assembly workmanship failure within the active factory warranty window, the manufacturer is refusing to cover the repair, alleging third-party tampering without physical or forensic proof. The failed hardware is being retained for forensic inspection.
Tesla just sold me a car with defective front half shafts axles. The car makes a reproducible and very concerning accelerator pedal shudder that makes the entire vehicle front vibrate, including the steering wheel and brake pedals while the car is accelerating between 30-60mph. This interferes with safety features like, lane departure assistance and blind spot steering wheel feedback, confusing the driver and creating a distracting scenario where an accident can happen. Upon bringing this to the attention of the service center in fort myers florida, the service center manager took a drive test with me, and was able to replicate the issue, but immediately started dismissing it as "normal" and within Tesla specs. This is becoming a regular practice at that service center, where they deem warrantable issues as normal and within (their tolerance). I insisted that this issue is not to be taken likely by Tesla, because it is something that involves a safety hazard. Upon further research, I was able to find that this issue is happening to many Teslas Model S and x, where the front axles bend due to the weight and high torque of the vehicles. The issue falls completely under warranty and the half shafts should be replaced, but apparently Tesla has instructed their service centers to dismiss and disregard the symptoms, and just tell the customers that no warranty replacement will occur, because it is not necessary, we just have to drive the cars like this, until the car completely fails, or an accident happens because one of the bent axle shafts breaks on a highway during normal drive. I recording this report as evidence that the issue has been reported to the highest vehicle safety authorities, and I expect a corrective action so Tesla can fix my car under the existing unexpired warranty.
Driving on straight section of highway at dusk. No autopilot or other features on. Road slightly damp from earlier rain. Driving approximately 60mph. Without me moving my hands or feet then car suddenly slammed on the brakes and speed decreased to approximately 20mph. I pulled over and reset the car computer by pressing the two buttons on the wheel and no further problems but had someone been behind me there would have been a terrible crash and my daughter was in the backseat. Looking online it seems Tesla "phantom braking" is not uncommon. I am frightened to drive my car ever again but have a 7 hour drive home tomorrow.
This is the second time in the last two weeks that my backup camera has stopped working. I have talk to the service center about this I was told that it is not a safety issue but a convenience to the driver and that I should use my mirrors and turn my head around to see what is behind me. I have taken my car in the service center to see if they can fix the problem (8/23/2023). Backup camera worked for a while than stopped again . I have made another appointment with the service center to see if they can fix the problem (8/29/2023.
At least 6 times on two different trips, while driving with adaptive cruise control engaged, the car randomly and aggressively applied the breaks. It was so aggressive that if there had been a car behind us, they would definitely have rear ended us going 60+ miles per hour. It was difficult to hold the car in the lane when the breaks were applied so aggressively. We did some research and found that there were over 700 comments on this problem and it was being labeled as "fantom breaking". The breaking is very aggressive and very unsafe. The representatives at the dealership simply acknowledged the problem and said that Tesla will continue to try to correct it with a software download.
