Multiple indicator lights are coming on when nothing is wrong with the vehicle, gradual loss of battery charge. Then my vehicle will not start at all. Nothing wrong with the starter, battery is still good, the alternator is fine. My indicator console will not come back on when I try to turn the car back on, car will not start without a jump, but all the lights inside and outside of the vehicle are on. I have found that this model year has a recall already on it for this same issue id # 13v173000 - electrical system. Nothing else seems to be wrong with the vehicle. Not sure at this point if it is safe to drive.
