Tesla Cybertruck Reliability by YearBest & worst years, problems & recalls — NHTSA data

PCS2 failure. The PCS2 board manages charging and power conversion. Failures typically start by restricting home AC charging speeds (e.g., dropping from 48A down to 24A) and can eventually result in a complete loss of AC charging and a "Charging Unavailable" alert.

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.

My 2025 Tesla Cybertruck AWD (VIN: [XXX] ) was returned to me after the first service visit (Invoice XXX Tesla Palo Alto, 8/22/2025) with the Pedestrian Warning System (PWS) speaker disconnected. The disconnection occurred during front-end service work at that visit, which included front fascia inspection and removal. The technician did not reconnect the PWS speaker before returning the vehicle. The disconnection was not discovered until the second service visit (Invoice XXX, Tesla Palo Alto, 9/18/2025), at which point Tesla's own invoice documented: "The issue was caused by a disconnected front pedestrian warning speaker. Technician reconnected the front pedestrian warning speaker to resolve the issue." The [XXX] s therefore operated with a disconnected PWS for approximately 4 weeks — from August 22 to September 18, 2025 — without my knowledge. During this entire period, the vehicle was not emitting the required audible low-speed alert. The PWS emits an audible alert at low speeds to warn pedestrians, cyclists, and visually impaired individuals of the vehicle's approach. This system is required under FMVSS 141 (Minimum Sound Requirements for Hybrid and Electric Vehicles). This is a service-inflicted deactivation of a federally-required pedestrian safety system. The deactivation was caused by Tesla's Palo Alto service center (4180 El Camino Real, Palo Alto, CA 94306) during routine warranty repair work. The vehicle was returned to me without disclosure of the disconnection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

One to two times per month upon starting my Cybertruck I receive multiple notifications for systems not working including "Driver Assistance - Automatic Emergency Braking is unavailable" and "Steering & Braking - Adaptive ride control degraded/Ride comfort may be reduced." These alerts cause the disablement of the regenerative braking, auto-hold (braking), emergency braking, adaptive ride control, traction control, and the self drive features. While the vehicle is still drivable, my ability to control the vehicle is greatly diminished, as is the safety of the vehicle without any of the accident avoidance and stability systems working. After driving in this condition, if I park the vehicle, exit it, and let it sit for at least 10 minutes, all systems are normal upon reentry. On 1/5 I experienced this issue and opened a service request for warranty work and Tesla demanded that I agree to a $200 charge before they would even look at it and said if they were unable to see the issue then it would not be considered as warranty. Since I cannot reproduce this issue on demand I cancelled the service request as I do not want to pay them $200 to say they couldn't reproduce the issue. Internet searches have revealed that this is a common issue among Cybertrucks and despite multiple software updates since owning my vehicle, it has not gotten any better.

Brand-new 2025 Cybertruck developed moisture inside sealed HV battery pack with no submersion, off-roading, or flooding. Service photos show only trace condensation and crystallized residue—no mud, corrosion, or contaminants. Tesla denying warranty and quoting $37k replacement. Suspected manufacturing defect in pack lid gasket (known issue in early VINs). Safety risk if unaddressed.

The contact owns a 2025 Tesla Cybertruck. The contact stated that while the vehicle was parked, the contact exited the vehicle and the front driver-side door independently closed and slammed his right hand in the door, injuring three of his fingers. The contact sought medical attention and was informed that he had sustained internal bleeding and was prescribed anti-inflammatory medicine and instructed the contact to try not to move his fingers in order to avoid disturbing the healing process. The contact stated he also sustained emotional distress and described the incident as traumatic. The vehicle was taken back to the residence and was not diagnosed. A dealer was not contacted, and the vehicle was not repaired. The manufacturer was notified of the failure, and the contact stated that the manufacturer said they would send an email after the call; however, the manufacturer did not send an email and refused to provide a manufacturer case number. The failure mileage was approximately 7,857.

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

Since purchasing my Cybertruck with Full Self-Driving in July 2025, I have experienced a repeated safety issue whenever Autopilot/FSD is engaged on highways. The vehicle will consistently pull toward the left side of the lane, positioning itself directly on the left lane line. This feels extremely unsafe, especially when another vehicle is traveling in the lane beside me. This behavior happens at highway speeds and creates a significant safety concern because it reduces the buffer between my vehicle and adjacent traffic. The issue has occurred repeatedly over several months in different locations and conditions. I have brought the vehicle to Tesla service multiple times, and the issue has not been resolved. Tesla acknowledged the concern happened to multiple vehicles in the past two months, but was unable to fix it. They are now performing another inspection for my vehicle, and starting a buyback request that is under review. There are no warning messages before or during the behavior. This appears to be a malfunction with the vehicle’s lane-keeping or Autopilot/FSD behavior that puts my safety and the safety of others at risk.

I’ve had a model 3,model y and now a cybertruck, can’t speak on the rest of the fleet but didn’t had this problem with those cars or any my other cars in the pass, but the passenger side seat belt keeps locking up, if you have to reach down to get an item or reach back it locks up, even if you go a few inches over it locks up which which needs constant taking the seat belt off and resetting it which become a safety issues while driving for the passenger, I took it to the dealership and they said it’s normal, I feel like the seat belt is short which makes it lock up as it should or other defect, I tasted on another cybertruck and didn’t had that problem, tesla customer service didn’t wanted to help me and push me away, I google the problem and there a forum and people having the same problem
