Known issues on the 2021 Accord. Four recalls are on federal record for this model year. The first covers the second-row center seat belt retractor, whose automatic locking feature can deactivate improperly and leave a child restraint system unsecured. Two separate recalls cover the front passenger seat weight sensor, which can crack and short circuit, failing to suppress the air bag or causing it to deploy unintentionally during a crash. The fourth covers the in-tank fuel pump, which can fail and cause an engine stall while driving, increasing the risk of a crash. Owners have filed 224 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From a seat belt retractor check to a fuel pump diagnosis or hybrid-system service, it keeps you on the OEM procedure and the correct specification for your specific 2021 Accord.
