I had the same problem with flickering lights on my 05 300c. I work for Chrysler. The dealer did the following to try and solve the problem. Change engine controller which controls voltages...no luck. changed Instrument panel cluster....no luck...changed headlight switch....no luck. I have a friend that is an engineer and he took the car to Aubun Hills Mich....to Engineering garage and they had it for a week......Conclusion ....Battery in trunk...causing voltage drop...nothing to be concerned about....some folks in engineering think the battery should be moved to the Engine compartment. My lights only fickered at 1500 rpm
