When I start up the car I hear a weird clunk sound. It only does it about 50% of the time but I find that mostly when the engine is hot. Anyone else have this issue?

You sure it's not pre-detonation? Hot engine and low octane can cause the this. BTW there was a TSB late last year where the PCM calibration was updated to avoid knock during acceleration on the SXT. I would check to see if this update has been done on your challenger if not would be good to get the latest calibration.

Wow, I really appreciate your help. Maybe just using premium gas will help avoid this you think? I will hit up the dealership and ask them about that as well. Sorry I am new to all of this. Will pre detonation cause further issues?

Seems to be a V6 problem, although I've never heard it myself
