Recalls for the 2020 Honda Odyssey: 14
Water may enter into the rearview camera, which can cause the rearview camera image to fail to display when the vehicle is in reverse. A rearview image that does not display reduces the driver's view behind the vehicle, increasing the risk of a crash.
The front passenger seat weight sensor may crack and short circuit, which can cause the air bags to deploy unintentionally during a crash. Air bags that deploy unintentionally during a crash increase the risk of injury.
A software programming error can cause the side and side curtain air bags to deploy unexpectedly. Air bags that deploy unexpectedly can increase the risk of injury.
The front passenger seat weight sensor may crack and short circuit, failing to suppress the air bag as intended. An air bag that deploys unintentionally during a crash can increase the risk of injury.
The fuel pump inside the fuel tank may fail. Fuel pump failure can cause an engine stall while driving, increasing the risk of a crash.
Due to a faulty Media Oriented Systems Transport (MOST) communication coaxial cable connector, the rearview camera image may not appear on the display. A rearview camera that does not display an image can reduce the driver's rear view, increasing the risk of a crash or injury.
The heating pads behind both side-view mirrors may not be bonded properly, allowing the mirror glass to detach. Detached mirror glass can reduce driver visibility, increasing the risk of a crash.
A manufacturing issue with the front seat belts may cause the seat belt buckle channel to interfere with the release button, preventing the seat belt buckle from latching. An unlatched seat belt cannot properly restrain the seat occupant during a crash, increasing their risk of injury.
The fuel tank assembly installed by Braun may be susceptible to the fuel tank overfilling into the charcoal canister. If the charcoal canister fills with a sufficient amount of fuel, fuel may leak out. A fuel leak in the presence of an ignition source may increase the risk of fire.
Incorrect central network software programming may cause several errors to occur that can delay or prevent the rearview camera image from displaying. A delayed or inoperative rearview camera display can reduce the driver's view of what is behind the vehicle, increasing the risk of a crash.
Incorrect instrument panel control module software can cause the instrument panel to not display critical information, such as engine oil pressure, speedometer, and gear selector position until the next ignition cycle. Additionally, it can prevent the rearview camera image from displaying. Operating a vehicle without a functioning instrument panel or rearview camera display increases the risk of a crash.
Water may get into the rearview camera mounting holes and enter the camera lens and cause a distorted image, or no image at all. Additionally, if the rearview camera view mode is set to top-down view, or switched from that view to another mode in a bright environment, the image may not display. A distorted or inoperative rearview camera display can reduce the driver's view of what is behind the vehicle, increasing the risk of a crash.
Water may enter the outer door handle cables for the sliding doors. If this occurs, the outer door handle cables may freeze in cold temperatures, preventing the front and rear sliding door latches from securely latching. A power sliding door that fails to latch may open while moving, increasing the risk of injury.
The wire harness for the third row seat accessory power outlet may get pinched between the unibody and rear trim panel, possibly damaging the wires and causing an electrical short. An intermittent electrical short could overheat the wire harness, increasing the risk of a fire.
