[09Tregger]

I have a 09 Treg with a 3.6L. On random occassions, usually only 5 times/year, when I start the car and drive, the voltage meter stops at 11 volts. After driving a short bit, the warnings usually come on making me aware of the low voltage issue as it starts shutting down various accessory circuits. If I pull over and shut it off, wait a few seconds, then restart, it comes right up to normal operating voltage. I bought this used several years ago and it has done this randomly the entire time. My question is, is there some relay in the charging circuit that has to turn on that is maybe sticking? Any other ideas? It has me a bit confused, especially since it happens so randomly. Usually happens more in the winter time.

I have a 08 Treg that did this. I search the internet and forms and found the there was a TSB about faulty voltage regulators on some of the Alternators. I tore into mine and found that the brushes were worn down. I ordered the correct part on Amazon and replaced it. We have driven for more than 2 months and no more issues.
