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?

Front. Almost like when my old car would shift into drive you could feel it.

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

Mine sounds like it’s in the front. Like transmission clunk
