The National Highway Traffic Safety Administration has announced that it is looking into problems reported on two Saab and Toyota vehicles. The Saab investigation involves 49,932 9-3 Aero sedans equipped with the 2.8L turbocharged engine.

Although no recalls have been issued, the NHTSA is investigating five complaints of a loss of braking power involving 9-3 Aero sedans. No injuries have been linked to the problem, although one accident has been reported.

The NHSTA has also announced that it is investigating complaints involving 2006-2007 Toyota Tacoma pickup trucks for unintentional acceleration. That investigation could impact 362,000 vehicles.

Toyota has had similar problems in the past with its Prius and Lexus ES due to defective floor mat.
