2013 Challenger SXT Plus ABS Brake Lights resetting and Neutral Safety Switch Clicking

Hi, I'm new to the forum and did some research already but couldn't find and exact answer to my issue.

My 2013 Challenger SXT+ is doing some weird stuff WHILE DRIVING; suddenly some of the dashboard lights (ABS, Brake, Traction Control) will go ON and OFF and the Battery light will come steady ON, while doing this the car keeps beeping, all gauges resets and the Neutral Safety Switch below the switch gear box is clicking.

I have 2 voltmeters attached to my car (one on the 12V outlet and one from my subwoofer amp setup) and they will peak up to 16V+ then come back to ~14V.

I also plugged a Foxwell OBDII (Chrysler) diagnostic tool and almost every module reads a voltage problem, check the codes below:

P0563 Battery/System Voltage High-
C004029 Brake pedal switch signal invalid
C210117 Battery voltage high - circuit voltage above threshold
C212A17 System voltage-circuit voltage above threshold
C212A85 System voltage - signal above allowable range
B210E Battery voltage high
B210B85 System voltage high - signal above allowable range

I am replacing the battery tomorrow but wanted to know if anyone has experienced this before and if the battery replacement is enough or should I be looking at something else?

Any comment or assistance will be VERY appreciated. Thanks in advance.

 

If the voltage is actually going up it's probably a intermittent bad diode in the alternator. You might be able to pinpoint this by having one of your DVM's set on AC volts and see if that really kicks up when you have the problem.
Also check around all the 12 Volt power supply areas for good connections on the plugs AND grounds. Battery, Power distribution in the engine bay and trunk, etc.
Welcome to the forum and keep us posted. We all like to read what the final solution was.
