I wouldn't lose any sleep over a reflash. But that's just me. "If it ain't broke, don't fix it".I also ordered and replaced the box myself while also adding the synergy track bar brace. My dealer kept telling me they wouldn't replace it because they couldn't duplicate the problem. I had about 1.5 inch play in the steering wheel and a pull to the right.
Drives great now, no pull, no wandering, and no dead spot.
Is it necessary to get the software update?
