The first thing I'd look at is the car's battery. Most modern cars, these not excluded, are very sensitive to voltage. Numerous systems can/are adversely affected when voltages are off, & many times they only have to be off just a touch to cause havoc.
Get a multi-meter & check the battery standing voltage then check things with the car running to see if your alternator is putting out.
