While driving on the interstate, I received a warning about an electrical system malfunction. As I neared my home, I received warnings about transmission failure, suspension malfunction, steering malfunction, sensor failure, and more. After a tow to the dealership I was told it is a generator/alternator (?) failure and the part is on national backorder and may be 3 months or more.
