Today I was changing my rear brake pads for the first time on my 2006 sonata. Like for many cars, I jacked it up on the rear tow hook at the back of the car. Big mistake! Now the bottom side of my trunk where the spare tire sits is caved in a little. Darn car doesn't have any jack points besides the pinch welds in between the tires! Question is how important is it to get it fixed? Does it connect to anything else that would cause it to become a safety hazard or is it just a cosmetic issue? Is it worth it to get it fixed or would it cost too much for a non-issue? I wonder if I could use a rubber mallet to pound the insides back out to even it a little. I feel kinda bad as I should of researched it more. Any help is appreciated! Thanks!
