2015 Ford Mustang GT: Self-Clearancing Trunk Deck Lid
by Jason Kavanagh, Engineering Editor on October 28, 2015
This scar on the underside of our long-term 2015 Ford Mustang GT trunk lid is self-inflicted. That is, it's the consequence of a build-quality issue rather than something that was user-induced.
Let's zoom out a bit. I noticed the abraded spot on the deck lid when I popped the Mustang's trunk. At first I assumed this was the outcome of some improperly-loaded cargo. But when I took a closer look it became obvious that it was not caused by impact.
That, and the half-inch scar is duplicated on the corresponding opposite end of the deck lid (see yellow arrows above).
The bit that's fouling the deck lid is circled above. The bottom edge of the plastic trim pieces adjacent to the taillights rubs the decklid.
Here's a zoomed-in look at one of the offending areas. Note the witness mark on the plastic and the paint dust on the bumper cover.
A quick search suggests we're not the only Mustang owners to observe this phenomenon. Were it my car, I'd probably hit the protruding plastic bits with some emory paper, give the scuffs a once-over with touch-up paint and call it good. But I am curious whether there's a proper fix to this issue that's been ginned up by Ford, like a set of replacement plastic panels or simply a trunk readjustment.
