Well, I looked under the car from the rear but I'm not "young" enough to crawl under enough to get a decent picture. I have a flat driveway into my garage but my neighbor has a steep grade in his driveway. When I see him outside, I'll ask if I can back up to the entrance of his garage and that should allow a better picture. But, I did cancel my appointment for a lift on Monday because something else came up. However, from what I can see, I do NOT have the dented area you have in the lower right of your left control arm assembly.
I also stopped by the car wash and talked to a knowledgeable manager. I explained that most of the time I get hard hits on the control arm while going through the wash but I have been through without the hits. I explained that I wasn't blaming the wash but trying to figure out why the control arm hit some times and not other times. Especially since the stated clearance for the Genesis V6 AWD sedan is 5.1" and my previous Chrysler 300S V6 AWD was 4.8 and I never hit anything in the wash with it.
The manager had me bring the car around so he could align it for a wash and check the clearances--it went through without a control arm hit! He told me to tell whoever is aligning cars for the wash that the sides of my left-side tires have to be 1" away from the guide bar that runs along the left side of the car.
Yes, everyone, I know not all car washes are the same, but this is what worked for mine at this car wash in Charles Town, WV. If I can get the car aligned this way every time, I won't hesitate using this car wash again, especially during the winter months.
