    Hemi 6.4 Gas Engine Knock

    Just adding an update. I emailed customer care and they have escalated the issue providing me with a case number and manager for this issue. He is supposed to call me today or tomorrow and I'll report what he says. I also received an oil test kit from Blackstone over the weekend and I'll be...

    Hemi 6.4 Gas Engine Knock

    Absolutely agree, but if I can't get it to happen again then I can't get them to tear it down and fix it. That's what sucks about it. I *know* there's a problem, and I'm kicking myself now for not letting the dealer 200 miles away tear it down while they were hearing it. Expensive lesson...

    Hemi 6.4 Gas Engine Knock

    2016 Ram 2500 with 23500 miles. The truck is still under warranty. So last week before my wife and I left on vacation I took it to my local dealer for an inspection, oil change, and tire rotation. The next morning we headed down the road. Stopped at about 100 miles and had lunch, no issues...
