Known issues on the 2021 Insight. Three recalls are on federal record for this model year. The first covers the DC/DC converter in the propulsion system: it may shut down and prevent the 12-volt battery from recharging, which can cause a loss of drive power and increase the risk of a crash. The other two both cover the front passenger occupant classification sensor: the seat weight sensor may crack and short circuit, and in each case that failure can lead to an air bag deploying unintentionally in a crash, raising the risk of injury. Owners have filed 24 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From a stalled drive-power fault to a passenger air bag inspection or routine hybrid service, it keeps you on the OEM procedure and the correct specification for your specific 2021 Insight.
