Known issues on the 2021 Odyssey. Eight recalls are on federal record for this model year. Braun-modified fuel tank assemblies can overfill into the charcoal canister, allowing fuel to leak near a potential ignition source. Improperly bonded heating pads behind the side mirrors can let the mirror glass detach, cutting into the driver's rear visibility. A faulty MOST communication cable connector can knock out the rearview camera image entirely. The front passenger seat weight sensor can crack and short circuit, twice named across separate recalls, which can either suppress an air bag when it's needed or deploy one unintentionally in a crash. A fuel pump inside the tank can fail and stall the engine while driving. Wheelchair restraint retractors on Odysseys built for mobility conversions may not lock, leaving a wheelchair unsecured in transit. And a software error in the air bag control module can trigger the side and side curtain air bags to deploy unexpectedly. Owners have filed 136 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're tracing a rearview camera fault, inspecting a mirror mount, or servicing the fuel pump, it keeps you on the OEM procedure and the correct specification for your specific 2021 Odyssey.
