What 22 owners told NHTSA about the 2025 Tesla Cybertruck (all Variants)

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.

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.

Driving the cybertruck on a road going straight no set destination on the cars navigation with autopilot on so it should have continued straight for the most part…. but the car decided to make an abrupt illegal right turn from a straight only lane after passing the appropriate right merge lane. After which the car swerved illegally into 2 oncoming traffic lanes before briefly missing an oncoming car then me driver manually pulled back into the correct lane. By the way my 12 pound dog which sits in the passenger seat was swung so hard hard by the abrupt turn that she literally ended up in the driver foot well by my ankles. This has never ever happened from my regular driving! I’m not so upset about my dog so much as I am trying to convey the amount of abrupt rough turn the car did. Very last minute and doing anything but let the car do the turn may have resulted in me crashing into oncoming traffic had there been any. A terrible illegal scary occurrence by Tesla autopilot. I was left very stunned. Please contact me for additional information I did record the dashcam footage and would like to share that.
