Hey all. First post here though I'm a member over at JeepForum as well. Bought my TH in July. Tired of freezing my buns off in my '74 CJ5 during Colorado winters. 05/15 birthdate. Haven't had any "issues" so far but I have noticed this same hard to describe noise if what I'm hearing is the same thing. I notice it most when I'm decelerating for a stop below 30 mph. "Grinding" is not a good description of it but there isn't anything better. If I didn't know better I'd say it sounded like deceleration exhaust note but that isn't it. And it seems to be intermittent. I believe it has something to do with the traction control system as it goes away if I turn off the system. In fact I can be hearing it and press the button and it immediately stops. Anybody else have this same experience? Other than that I've logged about 2600 miles and have had no other issues. The noise doesn't seem to be impacting anything else so I'm taking the same approach as others in asking the dealer at the first oil change. No impact on fuel mileage as I'm averaging 20-21 in town. Just got home this evening from a trip over the mountains to the west side of the state and averaged 27 mpg both to and from (four adults and gear loaded, AC on, over the continental divide from 6000' up to about 10k'). Interested in others experiences and if anyone gets a confirmed answer at some point.
