The National Highway Traffic Safety Administration said Wednesday it has opened two new investigations into Chrysler over complaints that the ignition key could shut the engine off involuntarily and may cause air bags not to deploy in a crash.
The investigations cover about 1.2 million Chrysler vehicles.
The agency started looking into problems with air bag deployments after similar ignition switch problems in General Motors Co. vehicles. GM has recalled 2.6 million vehicles cars with defective ignition switches. GM links the defective switches to at least 13 deaths.
