My 2012 Prius V. Clear coat is shedding off. Like a sunburn.

Clear coat typically comes off the plastic spoilers in the rear. Usually caused by cheap car wash's roller brushes over a period of time. Not much can be done aside from a respray, perhaps from a discount place like Maaco.

Squeaks are usually from the front suspension which can't be greased. Sway bar links or struts are common squeak points.

 

No clear coat, but the finish on the top flip surface of my rear spoiler is just becoming dull. The rest of the car is still brilliant Winter Grey Metallic.

 

That's what happens when a car sits in the sun and doesn't get regular cleaning and waxing. Yes, those mechanical car wash brushes will do a number on your paint, but also those high pressure water guns too. If you can find a shop willing to just respray the clear coat is the only way to take care of that.
You can spray WD40 or rubber restorer on the suspension grommets should temporary relieve the squeak.
