So for the last week or so the wife had mentioned that the rear end is making a pop bang noise once in awhile. told her it was probably the break sticking. Well tonight she pulls in a said it wont stop making noise. So I went out and could smell it before I got to the rear wheel. could feel the heat rolling out of rims when I bent over to feel the rim.. The rim was hot and that's a definite sign of a frozen brake caliper. So now I have to get in to see if that's covered under the warranty. If not I will fix it myself, which is bullshit if I need to fix it. We have had this vehicle now for 5 months and this is the second major issue and is making me think of getting rid of it already. If this is the kind of quality I can expect from Buick then I am done with them.
