I have a 2011 regal turbo with 30.000 miles and when you first start up the car with the air on a terrible rattle comes from the the belt or compressor. Does anyone else have this problem? If so what is it? Thanks!
Welcome. You probably have the Serpentine Belt and Belt Tensioner issue that is very common in this car. I had it done at 13000 miles two years ago. I am starting to hear the beginning of it again at around 25000 miles. Grrrrrrr.
