Electrical Issues that cause the interior devices to turn on and off.
2004 Kia Optima EX V6
My car used to have flickering lights and dim headlights. The sound of the radio would go in and out. One day, my car stopped while I was driving it. It turned back on immediately and it stayed on. This happened twice more, it started immediately both times. My alternator didn't have the proper output amps so I had it replaced. My battery and surrounding connections were tested and check out fine.
My car is acting crazy now, it doesn't turn off anymore but while I am driving, the radio, A/C, digital clock and dash lights (ABS, Emergency Break, Check Engine) turn on and off. Sometimes my car jolts when this happens. Everything turns on and off for a few seconds, sometimes a few minutes and then it drives normally. This is sporadic, I can't tell when it is going to happen and it can happen multiple times on one trip or not at all.
The mechanic kept my car for days and said they could't find the issue. My car has about 167K miles. Please help!
