On September 30, 2026, Yai V10, owner of a well‑known garage, became a hot topic online after appearing on a popular program to discuss how to inspect and repair flood‑damaged cars. Critics said he could not fully explain technical details due to time limits. In a recent live stream, Yai V10 affirmed his genuine experience in automotive repair and flood‑vehicle work, saying "the truth is the truth" and that he wants to share knowledge to help affected car owners avoid repeat repair costs. He stressed that after a vehicle is submerged, owners must prioritize the electrical system and control boxes, especially the MCU, which commands various vehicle functions. Although high‑voltage battery packs are designed with water protection, the entire car is not immune to flood damage. Inspections of EV electrical systems and control units should be performed by technicians with specific expertise or at authorized service centers; owners should not randomly open, test, or tamper with these systems themselves, as it may cause further harm. Yai V10 listed four essential steps for post‑flood vehicle care: 1) Check engine and gear oil for signs of water contamination, such as a milky appearance or over‑full dipstick; 2) Verify that all ECU boxes are free of water to prevent electrical shorts; 3) Clean the entire wiring harness; 4) Do not attempt to start the engine if any abnormality is found, particularly if the flood depth is unknown or the vehicle was heavily submerged—have a specialist inspect it first. He also warned owners not to rush to start the car just because water has receded, as hidden damage may still exist. A systematic inspection by qualified professionals is crucial to prevent additional loss.
