i just got a used 2013 chrysler 300c 5.7 and the 2nd day of driving i noticed my speedometer hit zero then go back to the speed i was driving. The next time it did this some of the dash lights would turn on and back off. i searched far and wide to try and find a solution or even a similar situation but had no luck. my headlights, interior lights, and cluster lights all flicker, not all the way off but in a dimming kind of way. any advice or a point in the right direction would be amazing, becuase this is driving me crazy.
