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.
2024 Tesla Cybertruck transmission complaints

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.
Normal night charging . Morning I get into my car I have alerts PCS2 saying I can't charge anymore at home . This is a huge safety concern as it's happened to many Cybertruck owners. If we go on a trip we can literally be stranded due to range and accessibility of chargers with kids. This needs to be fixed as a constant warranty even past 50,000 miles as the vehicle is not proven and in its early years. It's not a matter of if , it's when and creates unreliability and extremely heavy repair costs for an owner not due to personal wear and tear. Clearly a manufacture recall that should be monitored for a long long time.
Vehicle Safety Complaint - Tesla Cybertruck Steering System Failure During FSD While driving my Tesla Cybertruck with Full Self-Driving (FSD) engaged, the rear steering system failed without any prior warning. FSD immediately disengaged, and a red steering system ERROR appeared on the instrument cluster. The rear axle steering was completely disabled, turning radius became severely limited, and vehicle speed was restricted. This occurred while actively driving in traffic and was extremely dangerous. I accessed the vehicle’s Service Mode and documented three fault codes that triggered simultaneously at 17:48:14 on March 4, 2026: 1.RSAM_a260_monitorTripDetected ∙Monitor trip detected, system degraded ∙Potential Impact: Steering system performance degraded, vehicle speed limited ∙Only clears on next power-up 2.RSA_a212_activeFault ∙Rear Steer Actuator (RSA) stopped at current position ∙Internal condition detected, defaulted to safe state ∙Fault Reason: CONTROLLER_IRRATIONAL ∙Previous State: RSASTATE_ACTIVE_STEERING (was actively steering when failure occurred) ∙rsamControllerRational = false 3.PEPS_a182_rearSteerDegraded ∙Primary Electric Power Steering (PEPS) detected RSA not functioning as expected ∙Reason: RSA_UNHEALTHY ∙rsaUnhealthy = true ∙rearSteerCommand = -0.59 All three faults were set at 17:48:14 and cleared at 17:50:55. Additionally, an earlier alert — EGGRIGHT3_a203_airwaveLeftLateralUnavailable — was logged on March 2, 2026 at 21:11:08, which may indicate a related or recurring issue. The simultaneous failure of the rear steering actuator and disengagement of FSD while driving at speed represents a serious safety hazard. The RSA controller was flagged as “IRRATIONAL” while the system was in active steering mode, meaning the steering hardware failed during operation — not at startup or in a parked state. I have photographic documentation of both the dashboard steering ERROR warning and all Service Mode diagnostic screens showin
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.
