Yup. That’s it. Exhaust valves is what those are…I believe. The one on my drivers side is the one making the ****** terrible noise. With the hood open, the passenger side one has a rattle too just not as noticeable…yet. Good find…I’ll point this out to the service department and see what they say?
Are you running it in auto? I did after mine went out and I let it sit for an hour. Seems to work okay now, but I’m not confident it will hold up in the summer. At the time mine went out, it wasn’t hot out and only on a setting of 4 @ 68 degrees.
I traded in my ‘18 with 0 problems for this ‘23 that now has a couple issues. Love and learn I guess. Luckily, it’s not my daily so not a huge deal for me to take it to the dealer for a few days.
