Looks like the trim panel issue is like what they had on the 93-8 Grand Cherokee's. You either tried to repair or just replace them. When I worked at the dealers, parts, the tech's just replaced the panels. That way no one got married to a comeback.
It's funny, I'd never heard of such a thing until I got my 2016. Got it in April 2018 w/ 2086 miles, it went in service in August 2017, front passenger door panel was already warped, two rear followed in short order, drivers front only developed a small "bump". These panels appear identical in every respect to what I had on my 2013, never a problem in 5 years. While I was researching it, I found it was wide spread affecting other even high end manufacturers. I found the gorilla glue and popsicle stick fix on the charger forums. My dealer replaced all four, said the problem had been corrected. Now I'm not so sure after seeing this class action suit.
