More issues this week with automobiles, including an announcement from federal regulators they are investigating concerns about Ford Explorers. Some owners are complaining that they smell exhaust gas inside their vehicles. And another reminder about the Takata airbag recall. Owners of 300,000 older model Hondas (2001 to 2003) are being told to have their airbags replaced immediately. There is reportedly a 50 percent chance the bag could malfunction in a crash situation.
