'23 with 22k miles. Bad, loud metallic squeak on dips in the road. At first, sounded like the subframe was loose, but has quieted some, and sometimes is a low growl and grinding sound. Seems to be coming from the left front suspension somewhere. We'll see what the lexus warranty is worth. I hate the full plastic bottom cover when I'm trying to diagnose something like this. I typically diagnose myself and bring them in so I'm not buffaloed. As the sound changes by the day, I can't get in for a week. Hopefully something just came loose and can be found easily enough.

 

"Nothing found." Guess I'll have to get underneath and find it myself. Sucks heading into winter, and I don't have a car hoist either. Oh well.
