2024 Tesla Cybertruck Electrical Problems

On XXX at approximately 5:15 AM, I was driving my 2024 Tesla Cybertruck (VIN [XXX], ~47,300 miles) on an interstate trip to [XXX] with Full Self-Driving (Supervised) engaged. I heard a loud pop from the front of the vehicle, immediately followed by an alert stating the left front turn signal was malfunctioning and that I needed to take over control. FSD disengaged and I was forced to manually drive in pre-dawn darkness with a failed turn signal until the next charging stop. The fault then behaved intermittently: it cleared on its own, returned, cleared again, and I resumed FSD for much of the trip. Then, with roughly 100 miles remaining, the left turn signal malfunction warning returned while the vehicle was actively driving itself, again forcing manual takeover and leaving me without a functioning left turn signal in traffic. This is a serious safety defect on multiple levels: (1) A failed turn signal prevents me from lawfully and safely signaling lane changes and turns to other drivers. (2) The failure occurred WHILE the automated driving system was operating and depends on functional signaling to execute its own lane changes — yet the system had been driving with a component that failed audibly and without warning. (3) The intermittent nature means the vehicle can re-enter a hazardous state at any time, without warning, at highway speed. (4) I cannot get a service appointment immediately, so I must continue operating a vehicle with an unrepairable intermittent signal failure, exposing me to citations and collision risk. This vehicle has an extensive repair history including body panel adhesion defects related to Tesla’s 2025 cant rail recall, and this electrical failure continues a pattern of defects across multiple systems. No warning preceded the pop. The failure is reproducible in the sense that it has recurred three times in one day. Service records and buyback correspondence with Tesla are available on request.

Incident

Jun 15, 2026

The vehicle has experienced an issue with its power conversion system (PCS2) that leaves AC charging unavailable. Based upon online forums and social media, this issue is clearly widespread amongst early VIN model Cybertrucks. The scope of the issue has lead to delays with repair. My vehicle has experienced this issue since early June 2026, and I am still awaiting repair. This is a safety concern because it could plausibly leave the vehicle stranded due to lack of ability to charge the vehicle. While Tesla and third party superchargers are widespread, they are not everywhere and cannot allow a vehicle to travel to most roads in the United States. There have been circumstances where, if AC charging was not an option, I would have been stranded in a desert and surely would have died of excessive heat exposure. With the PCS2 failure, this issue a plausible risk.

I paid Tesla to perform a safety inspection of my Tesla Cybertruck after I purchased it. During that inspection, Tesla determined that the vehicle's as built configuration was **not safe** and required me to purchase a newer revision of the Power Conversion System (PCS). The required PCS revision did not exist when my vehicle was originally manufactured, meaning the vehicle could not have been built with that revision. The original PCS installed in my vehicle has a widespread failure rate among Cybertrucks. When the PCS fails, the vehicle is unable to charge, leaving it stranded. I believe this is a safety defect that warrants investigation by the NHTSA. Tesla's own words on their invoice state that the as-built configuration was determined to be unsafe, and required me to purchase a newer revision of the PCS (1777777-T2-G) to address the safety issue.

The car would stop charging at home and an error showed up about two months ago. After reporting to Tesla, they did a diagnostic over the air and concluded that the battery (HVB) needs to be replaced. The car is at the shop for over a month, and they are still waiting on parts.

I am filing a safety defect complaint regarding my Tesla Cybertruck. Water entered the truck bed outlet area and caused corrosion to the mounting bolts and surrounding components, resulting in Tesla determining that the entire bed wall panel requires replacement. The bed outlet is designed for outdoor use and exposure to weather conditions. In my opinion, water intrusion into this area represents a design defect because moisture can enter the electrical outlet assembly and associated mounting hardware, leading to corrosion and component deterioration. My concern is that continued corrosion could potentially affect the integrity or functionality of the electrical outlet system and create an electrical safety hazard for owners using the bed power outlets in normal outdoor conditions, including rain or vehicle washing. Tesla inspected the vehicle and confirmed water ingress and corrosion were present and advised that replacement of the bed wall panel was necessary to correct the condition. I request that NHTSA review whether the design of the Cybertruck bed outlet and surrounding components adequately protects against water intrusion and corrosion during normal vehicle use.

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.

Incident

Jun 2, 2026

My Tesla Cybertruck has experienced a failure of the Power Conversion System (PCS), which prevents the vehicle from charging at home using the installed residential charging equipment. Tesla diagnosed the issue and advised that the required replacement part is unavailable, with no estimated date for repair. As a result, I have been forced to rely exclusively on public Superchargers for several months. While Tesla has provided free Supercharging, this does not restore the vehicle’s intended functionality and requires significant additional travel, waiting time, and disruption to my daily activities and business operations. The vehicle was purchased and represented as capable of convenient home charging, and the prolonged inability to repair a critical charging system due to parts unavailability substantially impairs its use, value, and practicality. I am submitting this complaint because Tesla has been unable to provide a repair timeline, and I am concerned that other owners may be experiencing similar failures and extended delays in obtaining repairs. The offered loaner vehicle is a Tesla Model Y, which is not comparable to a Cybertruck and does not meet the hauling and cargo needs associated with my business operations.

Incident

Apr 10, 2026

My vehicle achieves only 80-100 miles of real-world range per charge, requiring charging to 100% to reach even this reduced figure. On April 30, 2026 at 11:08 PM, I documented energy consumption of 460.8 Wh/mi — 37% worse than the specification required to achieve Tesla's advertised range of 318-340 miles. Component: High voltage battery / power distribution system. Safety risk: Severe undisclosed range reduction means the vehicle may reach 0% charge in locations and at times the driver does not anticipate based on advertised specifications, creating stranding and safety risks. Manufacturer response: Raised on May 21, 2026 recorded call with Tesla corporate. Tesla acknowledged the issue and said to discuss at service — but all service appointments have been cancelled since December 2025.

All vehicle cameras failed simultaneously on May 12, 2026 at approximately 4:41 PM. Tesla app displayed "Cameras Unavailable — Please try again later." All camera-dependent systems were completely inoperable: Autopilot, FSD, Sentry Mode, dashcam/TeslaCam. Component failed: Entire forward and perimeter camera system. Vehicle available for inspection at Tesla Tallahassee Service Center. Safety risk: Vehicle cannot safely operate driver assistance systems with all cameras dead. Total loss of rear/side visibility systems while driving. No warning prior to failure. Manufacturer response: Tesla Pensacola general manager intentionally cancelled 8 consecutive service appointments — confirmed on recorded Tesla corporate call May 29, 2026. Owner drove 2.5 hours to one appointment and the GM rescheduled it without any notice. Tesla corporate agent confirmed on record: "You shouldn't have to travel to a service center that's over 100 miles away when you have one that's close to you." As of May 29, 2026 vehicle is at Tallahassee SC — Tesla refusing to provide a loaner or complete repairs. Owner has been without vehicle 24-48 hours despite being promised a loaner at time of tow. Prior warning: TeslaCam left-repeater camera failure events auto-saved December 15, 2025 — system was already failing 5 months prior to total failure. Was defect reproduced by dealer: No — Tesla refused to inspect despite 8 cancelled appointments.

In July of 2025, I drive my vehicle on a 130 mile trip. About 25 miles into the drive, I started receiving errors about AC charging not available. I stopped at a Tesla supercharger Hannibal [XXX] but I couldn’t charge it there either. Drive it the rest of the way to my destination where I had an ac charger available. Tried there but I couldn’t charge there either. Tried resetting the car…still couldn’t charge. Opened service ticket. Tesla had to send a tow vehicle 110 miles to me and then tire the truck back to the service center in [XXX] . they had to keep the car 3 days and replaced the pcs system.

Incident

May 15, 2026

I have fell victim to the now infamous PCS failure. My truck stopped being able to charge from home, and Tesla requires me to use their Supercharging system in order to drive it. I was actually around the truck when it failed and could smell a potent odor of electrical smoke coming from outside the vehicle. I have observed the same odor every time I’ve charged it since. Tesla will not accept the vehicle at their service center because they are back ordered on the part by over eight weeks.
