I bought a new 2012 CTS. When I get on it a little bit just before it shifts gears it makes a sound that sounds like all the baffles in the muffler or cat is going to fall out. I took it my dealer and they hear it also. They took another 2012 CTS and it does the same thing.
I got a case number from GM (71-1061884386). They tell me there is mothing they can do. I have had 5-6 people tell me that the car sounds like it is falling apart when I step on it. The dealer hears, GM knows about it and will not do anything. What do I need to do to get some results. I did not buy a new $45,000.00 car to have something that sounds just awful. I am not bad mouthing the dealer, they have done everything they can at this time.
Anybody else have this problem?
