Known issues on the 2020 Civic. Five recalls are on federal record for this model year. Two separate campaigns cover the in-tank low-pressure fuel pump, which can fail and cause an engine stall while driving, increasing the risk of a crash. A third covers the brake master cylinder: a tie rod fastener connecting it to the brake booster may have been improperly assembled, letting the master cylinder separate from the booster and causing a loss of brake function. The remaining two campaigns cover the front passenger seat weight sensor, which can crack and short circuit, failing to suppress the air bag as intended and allowing it to deploy unintentionally during a crash. Owners have filed 221 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From tracing a fuel pump stall to inspecting the brake booster-to-master-cylinder connection or checking the passenger seat sensor, it keeps you on the OEM procedure and the correct specification for your specific 2020 Civic.
