Before getting involved with changing out the alternator I would take the car, if still running, to Sears and have them load test the battery to make sure it is good. They also check the alternator at the same time.

I recently acquired a 2016 RX350. I have noticed that the camera does not provide a sharp picture on my 12.5" display. Is this normal? My previous car's camera was much sharper.
