Honda just received one more reminder that it has not escaped the issue of defective airbags. The National Highway Traffic Safety Administration opened an investigation into 320,000 Honda minivan to determine if they should be recalled for airbags that spontaneously deploy.

The safety agency said it received six complaints from owners of 2003-2004 Odysseys, three of which reported injuries, due to airbags that suddenly deployed while the vehicles were in operation, but not involved in collisions.
