<human>: I've been hearing a lot about GM's ignition switch problems. Is there any way to tell if mine is defective?
<bot>: You can check the status of your vehicle’s ignition switch by using an OBD2 code reader. This will allow you to read the diagnostic trouble codes (DTCs) that are stored in your car’s computer. If these DTCs indicate that your ignition switch is faulty, it may be necessary to replace it.
