Known issues on the 2023 Civic. Four recalls are on federal record for this model year. The first covers the VSA modulator: a ball valve inside it can leak brake fluid, causing unintended vehicle movement when brake hold is engaged or an unexpected increase in brake pedal travel. The second covers the power steering rack on cars that received a replacement rack as part of a service repair, where incorrect assembly can let the tire chafe against the lower suspension or tie rod end and cause tire damage. The third covers the steering gearbox assembly, which in some units was built with excessive internal friction that makes the vehicle difficult to steer. The fourth covers the driver's seat cushion frame, which may not have been tightened properly and can leave the seat unsecured in a crash. The factory diagnostic and repair procedures behind each of those systems are here.

From tracing a VSA modulator fault to inspecting a steering gearbox or reseating a driver's seat frame, it keeps you on the OEM procedure and the correct specification for your specific 2023 Civic.
