NEW YORK --- General Motors will be recalling 181,516 Chevrolet HHR wagons because some of the vehicles don't meet government standards for protecting occupants from head injury in a crash, CNN reported.

GM said that Chevy HHRs not equipped with optional roof rail-mounted airbags and sold between 2006 and 2008 have  failed the company's own side-impact tests. Roof rail-mounted airbags are designed to reduce the risk of head injury during a side-impact collision.

The recall will start in late March, when the parts become available. Dealers will install a piece of energy-absorbing plastic to the headliner trim.

In 2007, about 99,000 Chevy Cobalt sedans were recalled for a similar problem.
