The Power Conversion System (PCS) in the Tesla Cybertruck is experiencing a high rate of hardware-level failure (specifically the PCS2 module) that poses three distinct safety risks beyond the loss of AC charging. Loss of Steer-by-Wire Integrity: The Cybertruck utilizes a full steer-by-wire system and a 48V low-voltage architecture. The PCS is responsible for managing the 48V bus and charging the LV battery. A hardware failure in the PCS (common alerts: PCS2_a094, PCS2_a137) threatens the stability of the 48V system. Any sudden collapse of the 48V bus while in motion could result in a total loss of steering control and vehicle maneuverability, creating an immediate risk of a high-speed collision. Loss of Propulsion and Stranding: PCS failure frequently leads to "limp mode" or a "no-start" condition where the vehicle cannot engage Drive or Reverse. Experiencing a loss of propulsion while in active traffic or being stranded on a highway shoulder without the ability to move the vehicle creates a severe life-safety hazard for occupants and other motorists. Failure of Visibility Systems: Critical safety components, including the primary windshield wiper and exterior lighting, are powered via the 48V system managed by the PCS. Hardware instability has led to reports of these systems failing during inclement weather, severely compromising driver visibility. Tesla has implemented software bypasses (OTA updates) to allow DC Supercharging when the AC hardware fails, but this is a "band-aid" that does not address the underlying hardware defect—likely MOSFET degradation. With replacement parts on backorder for 8+ weeks, owners are forced to operate vehicles with compromised electrical architectures. I am reporting this as a systemic hardware defect that requires an official safety recall.

My 2025 Tesla Cybertruck AWD (VIN: [XXX] ) has a recurring failure of the right rear seat occupant detection system, which governs airbag deployment and is certified by Tesla to meet FMVSS 208. The same alert (internal code RCM2_a698) persisted through two official repairs at Tesla Palo Alto: 1st repair (Invoice XXX, 8/22/2025): seat belt buckle replaced. Alert recurred 2 days later, August 24, 2025. 2nd repair (Invoice XXX, 9/18/2025): harness assembly replaced. Tesla then performed a Visual Quality Check, recording in the invoice: "Technician performed a visual quality check to ensure its condition meets our standards." Vehicle returned as repaired. Relying on Tesla's written certification, I reinstalled my [XXX] son's car seat in that position. He rode there daily for approximately 7 months (September 2025 - April 2026). On April 21, 2026, I tested the seat and found the sensor still actively failing - unable to detect an adult occupant. My spouse witnessed this. I have 30-second video. Alert RCM2_a698 remains active in Tesla's systems today, confirmed by screenshot. This is my family's only vehicle. My wife currently uses the right rear seat. Airbag deployment for that seat cannot be relied upon. Tesla has been notified and has not resolved this issue.

HTSA Safety Complaint Description The 2025 Tesla Cybertruck exhibits a persistent and recurring air suspension system defect that impairs safe vehicle operation. From the moment of delivery, the air suspension failed to raise or lower properly, displaying a fault message indicating potential restoration on the next drive. This did not occur. The issue included repeated overheating warnings, multiple system failure alerts, excessive compressor noise/knocking, steam and water discharge from the undercarriage, and the vehicle remaining stuck in a lowered ride height, causing scraping damage to underbody trim and mud flaps. The vehicle underwent a major warranty repair where the air suspension compressor was replaced due to a stuck exhaust valve and damaged air line, followed by recalibration. Despite this, suspension overheating warnings and intermittent system failure notifications continued to appear. On December 23, 2025, while driving at moderate speed in clear conditions, the vehicle suddenly and uncorrectably migrated off the roadway. Adaptive steering correction, braking intervention, and lane assist failed to engage. At the time of the incident, the display actively showed service notifications indicating suspension system failure and overheating. The vehicle veered into a ditch, resulting in a significant drop and requiring specialized heavy-duty extraction. This defect has impaired the vehicle’s handling, stability, and safety from delivery onward, with no resolution after attempted repair. The recurring nature and active failure alerts during the loss-of-control event suggest a serious safety risk.

Tesla sold me a 2025 Cybertruck RWD without disclosing that no compatible bed cover exists at all for this model. We test-drove the vehicle at Tesla Clermont and took delivery at Tesla Tallahassee. At neither location were we told that the RWD trim cannot use the powered hard tonneau cover OR the soft tonneau cover. After delivery, Tesla confirmed in writing that the only cover associated with this model is out of stock with no ETA, and they “cannot speculate on availability.” No third-party manufacturer offers a compatible cover. This means the vehicle’s truck bed cannot be covered or secured in any manner. As a result, we experienced two serious safety incidents. Both times, the vehicle was operating in SFD (self-drive) mode at speeds below the posted speed limit, with items properly tied down using rope. Even under safe, controlled conditions, items flew out of the truck bed twice, nearly causing a collision behind us. Vehicles had to brake and swerve to avoid debris. These incidents created a direct hazard to us and the surrounding traffic. The Cybertruck RWD cannot safely retain cargo under normal driving conditions without a cover, and no cover exists or can be purchased. Tesla buried a clause in a 45-page contract saying they may “remove parts from commerce,” but this does NOT excuse failing to disclose that no safe cargo-retention solution exists for the RWD configuration. A pickup truck that cannot keep cargo from ejecting onto the roadway presents a serious safety defect. I am reporting this because the inability to secure a load is a safety hazard for both occupants and other drivers, and Tesla has no remedy available. Thank you
