2024 Tesla Cybertruck: sudden loss of power

Filed Sep 28, 2026 · Airbags, Electrical · CT

While driving on a highway with Full Self-Driving engaged, I approached an exit and applied steering input to take control. I expected the system to disengage and the Cybertruck to follow my steering input. The vehicle did not respond in the manner I expected and left the paved roadway, entering a grass field. To my knowledge, it did not strike another vehicle, guardrail, tree, or structure. The airbags nevertheless deployed, and a collision event was indicated. I cannot determine from my observations what triggered the restraint system or whether contact with the ground or another condition played a role. After the vehicle came to rest, it lost power to the extent that it would not operate normally and I could not access parts of it by the usual means. Tesla personnel attempted to supply external power but could not restore normal operation. They ultimately had to force access to the trunk to retrieve belongings. The disabled vehicle was towed to Tesla’s Mechanicsburg Service Center and then to Sun Motors Collision Center. I notified Tesla and requested an explanation specific to this incident. Tesla has provided me with vehicle data through its privacy process. Unfortunately, Tesla stated most of the data was unavailable without explanation, such as video recordings and event data. In correspondence through September 17, Tesla referred to general driver responsibility and collision-related warranty coverage, but I have not received a technical explanation that resolves the steering behavior, the airbag deployment, or the power loss. I have followed up with Tesla multiple times. Their final response is "We don't comment on causes." They refuse to provide any other information or support the warranty. I do not know whether a vehicle system malfunction caused or contributed to the roadway departure or whether the later events were consequences of the departure.

PCS system has failed. This causes the vehicle to be unable to charge and can lead to loss of power if unable to get to a supercharger before the battery is depleted. It can now only be charged at full Tesla superchargers and not at other brands, hotel chargers, or home AC chargers. The vehicle did notify me of the PCS failure and recommended using a supercharger. Tesla proactively updated my account to allow for free supercharging, but this does not eliminate the risk when going to areas that do not have superchargers available. Parts are not currently available to repair the problem and my service requests are left in a "review" state. Vehicle is available for inspection if needed.

Beginning approximately December 2025, my vehicle produces a severe grinding sound when attempting to accelerate. The sound has been consistent and ongoing for approximately 6 months. Confirmed verbatim on recorded Tesla corporate support call May 21, 2026: "If I try to accelerate it's making this horrible grinding sound. This has been going on since December." Component: Drivetrain / power unit (unknown — Tesla has never inspected). Safety risk: Grinding on acceleration indicates mechanical failure in the drivetrain that could result in sudden loss of power or vehicle control. Manufacturer response: Tesla Pensacola GM intentionally cancelled 8 consecutive service appointments since December 2025 — confirmed on recorded Tesla corporate call May 29, 2026. Owner stated on Tesla's recorded line: "For the last two years it's been broken. I've literally had it in the shop more than I've driven it." Tesla has never examined the source of the grinding sound. As of May 29, 2026, vehicle is at Tallahassee Service Center. Tesla escalated to Regional Manager on May 29, 2026. Available for inspection: Yes — vehicle at Tesla Tallahassee Service Center.

This incident happens when driving home from work, it happened half a mile away from where I live on a local road. All of a sudden car lost all power, steering wheel and brake completely failed, drive train completely failed while the car was still moving. there was no way the car could be controlled to move to the side of the road or to break to completely stop it.. thankfully it coasted to a complete stop. As it was the middle of the day, there were no cars around the local road I was on. Once the car stopped everything shut off completely. There was no way to turn on the hazard lights or get out of the car either I had to use emergency exit.. car wash towed to Tesla service center where it stayed with them for a few weeks and I was told that it was PCS an ancillary auxiliary part that needed to be replaced. While searching the forums, I found out that this is becoming a problem where multiple cyber trucks have this issue going on which I feel is a safety issue as it can cause a major accident or fatalities if somebody was driving on the highway on highway speeds and this happened. I am opening this ticket to help others so hopefully a recall is done on this.

My Cybertruck’s Power Conversion System failed at ~65,000 miles. I received a PCS alert, AC charging became unavailable, and the vehicle displayed charging faults. The repair required major disassembly of the tonneau, bed, and air suspension and cost $7000 because it occurred after warranty. Why This Is a Safety Defect: The PCS is a critical component that handles onboard AC charging, DC-DC conversion to the 48V system, and power delivery. Failure can strand drivers, prevent charging, and (as seen in related drive-inverter recalls) contribute to sudden loss of propulsion while driving. This Is a Widespread Issue: PCS failures are occurring frequently (“left and right”) in Cybertrucks, especially early production models. Owner forums and polls show dozens of identical failures, with some samples reporting 18–40% affected. Many owners face $2,000–$7,000 repairs out of warranty. Tesla issued a limited recall for related drive inverters (the federal safety agency Campaign 24V‑832) that can cause sudden power loss, but no recall covers the broader PCS defect despite the clear pattern. I strongly urge the federal safety agency to investigate this common defect immediately and require Tesla to issue a full recall for affected Cybertrucks, including free replacement of the Power Conversion System for all owners. Thank you for protecting public safety.

While driving on a local road and thank fully at speed of 20mph vehicle lost all power, in few seconds of alerts steering failed as well as brake failed. Car slowly coasted to stop and died completely. Steering and brakes were completely unresponsive all of a sudden while driving. Was only able to get out of car via emergency exit. If this was on a highway at highway speed am very positive it would have been a disaster.

On [XXX], [XXX] was a right rear passenger in a 2024 Cybertruck. The driver lost control and struck a tree with the driver side against a wall. The truck immediately caught fire. The operation of the doors was powered by a small battery pack which was no longer operational after the impact. The passenger side doors operate off of that battery. Without power, the passenger doors could not open, trapping the driver and passengers in the Cybertruck. The fire moved quickly to the passenger compartment and towards the trapped passengers. The design of the electric doors required passengers who are not familiar with the vehicle to find the location of a manual release hidden from view beneath a panel to remove that panel and pull the manual release mechanism. There are no instructions present to explain to a passenger how to access the manual release. The truck has no exterior door handles. The only means to open the door from the outside was a button located at the base of the B&C pillars. When the electric system failed, that door release button became useless. A rescuer arrived but had no way to open the passenger side doors from the outside. The truck’s “armor glass” windows made forcing entry extraordinarily difficult. The rescuer was able to break the passenger side window with repeated strikes and attempted to rescue [XXX] by extracting her through the front passenger window but was unsuccessful due to the heat from the fire. She was forced to retreat back to the rear seat. She survived the initial collision with no injuries and was fully conscious. She was unable to escape the Cybertruck and was killed due to smoke inhalation and thermal injuries. The failure of the vehicle’s design to provide emergency egress in the event of crash, power loss, and fire created a foreseeable and unreasonable risk of occupant entrapment and death in the event of a collision resulting in power loss. It is available for inspection by the federal safety agency. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

I am leasing a 2024 Tesla Cybertruck and have experienced multiple serious and unresolved safety issues. When driving at speeds of 50–60 mph or higher, the Cybertruck begins to shake aggressively, particularly in the front wheels. The vibration makes it difficult to maintain control. I took it to the Tesla dealership, and service staff confirmed there is a known malfunction with the Cybertruck tires. They informed me they are waiting on new tires to arrive, but offered no timeline and sent me home with the issue unresolved. No loaner vehicle was offered, no workaround was provided, and I am still driving a vehicle Tesla knows is defective. In addition, the rear windows malfunction frequently. When I close the rear doors, the windows often jam or freeze. This concerns me because the Cybertruck is built entirely with electronic door systems—there are no manual overrides. If power is lost during a crash, occupants may not be able to exit. This is even more alarming in light of recent reports of Cybertruck-related deaths. Multiple individuals have died in crashes where the battery was damaged or the vehicle caught fire. Power loss caused the doors and windows to become non-functional, and due to Tesla’s armored glass, bystanders couldn’t break the windows to rescue the victims. These people burned alive while trapped inside. This is not a theoretical issue—it has happened. Despite these risks, Tesla has not issued a recall or urgent fix. I’ve made multiple efforts to resolve these problems, but Tesla’s delays, denials, and lack of proactive safety measures are deeply negligent. This is a dangerous vehicle, and I am requesting that the federal safety agency immediately investigate both the front-end tire instability and the entrapment risk caused by electric-only doors and unbreakable windows. I no longer feel safe driving this Cybertruck and believe others are also at serious risk.
