I finally got tired of looking at the hood gap, so at the advice of
@mrcleeaan I contacted Genesis USA instead of visiting the dealership and opened a case with pics attached. Very good experience with them and they seemed to genuinely care about the issue. They said the first step is to take it to my local dealer for evaluation and they were kind enough to make the appointment for me. Since I didn't want to waste my time, I called the dealer and was told they's look at it, but if it turns out to not qualify as warranty work, I'd be charged for the loaner car. I reluctantly agreed and continued with the appointment. To my surprise, a few minutes later the sales manager called me to setup a valet appointment and said I should not worry about being charged for the loaner car. Very cool! Hmm I wonder if this happened because I called Genesis USA first??
They picked up my car, an hour later I was called by the service advisor where he agreed it should be within warranty to have it repaired. He then asked for my permission to take it to a local body shop, I said sure. In my case, there was both a gap and flushness issue with the hood. After a couple hours he called me back saying the flushness issue was resolved (likely by adjusting the latch and rubber stops), but the gap is still there. He said he was told by the body shop manager that the hood on the G70 CANNOT be adjusted at the hinges to close the gap. They said this car was built with no means for hood alignment, only the height/flushness relative to the fenders and front fascia. It seems true that there are no "oval" slots that I can see, so technically I guess that means they are not adjustable.
Overall I was very happy with how the dealer handled the issue, but unhappy with the result. The service advisor told me that if I can find a body shop that can fix it, I should call him back and he'd see about arranging the repair.
So my question to you all is... has anyone successfully had their hood realigned for better fitment? Looking at the hinges, there are 4 bolts (2 upper, 2 lower) on each side. I would think that by loosening these just enough to allow slight movement, then re-tighten, it may be enough to correct the issue. I just hate to try this myself for fear of chipping paint. I may visit another local body shop and ask if it can be done. Thoughts?
