I'd pick up the two parts from Kia and a tube of their 'special' lube, take the whole lot to a decent mechanic along with the TSB that explains how to deal with it, and let the independent shop have a go at doing it the way Kia recommends.
Think about it. Even if the track were warped/bent and had to be replaced, why on earth would anyone replace the glass panel? You're getting quoted the entire assembly+ from the dealer. You're getting hosed there, friend.
Thanks! Just saw someone posted that TSB up earlier in the thread. This thread is gettin so long its gettin hard to sift thru. $150.00 for the Kia lube, must be real good stuff.
All the discussion on panoroofs was lookin at mine and it needed a little maintenance clean and lube too. A lot of dust and some pine needles in the gutters. No pine trees around me. Cleaned up now just waitin on lubes in the mail.
Yeah, here it is again for any who started late. Third iteration.
To the recent poster with the dealer with the crazy prices, the TSB specifically states "Do NOT replace the sunroof assembly for this concern."
