Cybertruck MOSFET failure at 31,250 miles
- Tesla owner reporting through Torque News said on May 16 a 2025 Cybertruck AWD logged a PCS2 MOSFET health-check failure at 31,250 miles. - The service-mode screen showed code “PCS2_a136_cycloAMosfetHealthCheckFailed,” while the owner said Tesla enabled free Supercharging after a 9:30 p.m. service request. - Owners can check Tesla and NHTSA recall tools for open campaigns while waiting for Tesla service scheduling.
A 2025 Tesla Cybertruck AWD developed a PCS2 MOSFET health-check failure at 31,250 miles, according to a May 16 Torque News report that cited the owner’s service-mode screen and account of the service process. The report said the owner opened a Tesla service ticket that night and later received an automated response saying free Supercharging had been enabled while scheduling was pending. Tesla has issued a separate Cybertruck recall tied to MOSFETs in drive inverters on some 2024 vehicles, but the reported truck in this case was described as a 2025 model. NHTSA’s recall lookup page says VIN searches show unrepaired recalls and that manufacturer service campaigns that are not safety recalls may not appear there. ### What exactly failed on this truck? Torque News said the active alert on the truck’s service screen was “PCS2_a136_cycloAMosfetHealthCheckFailed.” The description shown on that screen said the Power Conversion System self-performed MOSFET health check was unsuccessful on “Cyclo Converter A,” according to the report. (torquenews.com) The same May 16 report said the truck was in Service Mode and displayed “Speed Limited” on a red lower bar. Torque News also said the charging panel showed the battery at 54%, an 80% charge limit, 6 kW charging power, 24/24 amps, 241 volts, and an estimated 4 hours 55 minutes remaining. ### Did the truck stop charging completely? (torquenews.com) Torque News reported that the truck could still be plugged in, but the screen showed a power-conversion health-check failure alongside what it described as reduced-looking AC charging behavior. The publication said that combination suggested a symptom pattern rather than a complete reconstruction of the repair outcome. (torquenews.com) Drive Tesla reported on April 22 that Tesla had begun offering free Supercharging to affected Cybertruck owners waiting on repairs tied to Power Conversion System failures. That report, citing an update from Kyle Field on X, said a firmware update was being rolled out to restore limited functionality and allow Supercharging while AC charging was down. (torquenews.com) ### Is this the same issue as Tesla’s Cybertruck MOSFET recall? Tesla’s Cybertruck drive inverter recall covers certain model year 2024 vehicles built from November 6, 2023 to July 30, 2024 that were equipped with specific MOSFET components in the drive inverter, according to Tesla’s support page. Tesla said a fault in the drive inverter may cause it to stop producing torque, creating a loss-of-propulsion risk, and that the remedy is inverter replacement. (driveteslacanada.ca) The May 16 Torque News report said Cybertruck owners had already seen MOSFET language in another issue, but it did not say the 2025 truck’s PCS2 alert was itself part of that recall. Based on the documents reviewed here, the reported failure involves the Power Conversion System, while Tesla’s published recall concerns MOSFETs in certain 2024 drive inverters. (tesla.com) ### Why did Tesla enable free Supercharging? The owner cited by Torque News said Tesla enabled free Supercharging after the service request was submitted on May 15 at about 9:30 p.m. Eastern, with an automated response arriving around 10 p.m. The publication said that showed a temporary charging accommodation in this reported case while service scheduling was pending. (torquenews.com) Drive Tesla reported earlier in April that Tesla was extending free Supercharging to affected owners because some trucks with PCS failures could not use Level 2 AC charging at home while waiting for parts and repairs. That report said Tesla had not announced a formal recall for the broader PCS issue. ### How can owners tell whether their truck has an official recall? (torquenews.com) NHTSA says owners can search by VIN or license plate to see whether a specific vehicle has an unrepaired recall. The agency also says VINs can be added continuously and that non-safety service campaigns may not appear in recall results. Tesla says Cybertruck owners affected by the published drive inverter recall can also check their VIN through Tesla’s recall search and schedule service through the Tesla app. (driveteslacanada.ca) For the reported 2025 Cybertruck PCS2 case, the next concrete step described in the available reporting was Tesla service scheduling after the May 15 ticket and the temporary use of free Supercharging while the owner waited.
