At about 1566 miles on my 2WD, Touring, I heard a new maybe, small clunk today. I pulled into a small parking lot at Houston Med Center area doctor for wife. The small lot was full so I let her out and backed out into the street again. As I was in reverse, turning to the right but not to full-wheel-lock, I heard a minor clunk/thump at right rear. Or so it felt like it came from that area.
From what some have suggested here, it's hard to know if these intermittent sounds are part of the brakes/drivetrain/suspension system and are ok to live with? I guess, going to the dealership and have them check it out is the only way to really know.
I'll be watching here and following along....and listening to my Touring for any new noises, sigh.
