Hey gang, I think I'm having a voltage issue with my GT. When the AC is on the volts go from 14.5v to 13v then in a few seconds go right back up to 14.5v and when that is happening, you can hear the fans power down and power back up again.

And when I was driving home CLEAR Traffic. I voltage was a steady 13.1v

Am I bugging or did this happen to someone else?

Steffon:
I would have the battery load tested to rule it out. If it passes, the alternator or section of the PCM that controls it might be in question.

I had the exact issue on my 2019. I plugged my obd reader and gave me a code about voltage drop for a while. I took it to the dealer and they said it was both batteries were defective. replaced both of them under warranty

RIP-

Thank you. My Gt is at the dealer now. They said there was no codes but they diagnostics to my car. Hopefully they find something.

So just brought my 21’ SXT in for a different issue. I also noticed the same thing with the voltage on the battery display. I also checked it with a Fluke meter at idle 12.8 volts. Dealer ran a scan no issues and also told me there is a clutch on the alternator. The alternator will turn on/off per the technician and not to worry about the fluctuations in voltage. I have never heard of that on a alternator but okay. The issue I brought it in for was at hard acceleration the engine seems loud almost like a air intake leak. They did not find any issues. This is a company lease vehicle already put 16k miles on in 6 months! Other than that I really enjoy driving this thing.
