It has been a really busy week since I got home w/ HG 4336 and I haven't had time for making any reports, but yesterday I noticed the trailing end of the plastic trim piece in the roof gutter had come loose. I can see a white plastic clip underneath, but I think it may be a combination of not enough glue and a clip failure. I decided right then it was time to visit the local dealer Monday morning for an oil change (1550 miles now) and to hopefully get this repaired. Anyone else have this problem? Hmmm, might have to order one of those cool plenum covers, too!
