The plastic piece on driver's seat with electric controls is hanging due to broken tabs. I'm shocked to find this is $267 to replace and not under warranty. The dealer has the part in stock and admitted it is a common problem. After discovering this blog, I see it has been a problem for years. Why don't they fix this obviously poor design? I'm sure it is an inexpensive part for them and a huge money maker. No more Buicks in my future!
