"The side-impact sensor calibrations may be overly sensitive, and as a result, the side airbag curtains and/or seat airbags may unexpectedly deploy when the ignition is on and the door is slammed or there is an impact with road debris," NHTSA said in its recall summary. "Airbags that unexpectedly deploy increase the risk of a crash or injury."
There are 19 injury claims, 311 warranty claims and 160 field reports, Honda told federal safety regulators.
A stop-sale order on the cars was issued to Honda dealers on October 20.
