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.
