well I have a 2.2 auto and some times when I start it I get a grinding sound but it goes away when I apply gas. when I slow down I get like a grinding/whinnying sound from the front breaks. and I have a busted heat shield on the exhaust. What should I do about these? took it to the dealer where I got it and it did not do it for them so they just said drive it and see what happens. any information would be very helpful. car has less than 2000 miles.

 

Take it back for warranty work again. Maybe try another dealership.
