look, i really want to like this car but it's driving me insane. first of all i have that incessant squeel/high pitch frequency that only goes away when i dim the lights to a point where i can barely see the dash cluster. two, my back in creaks and moans when i go over things like speed bumps; it sounds like the car is a hundred years old! three, at low speed and low rpm (going up the hill to my house) i get a vibration that sounds like metal panels are vibrating to their resonance frequency somewhere behind the passengers side firewall. and lastly, i get alot of jerking and jarring at low shift points. its like the trans isnt catching and then finally gets ahold of the gear; usually from a slow roll or from coming out of any low speed. i took it to the dealer and they told me that all things were normal! that the last problem was indicative of all gm's torque converters and that i will always have that stutter and jerking motion. and that the vibrations were normal and the creaking/moaning from the rear is just something needing lubricated. its a 2010 black 1lt that looks pretty nice and feels nice to drive, however i expected more from my first brand new car. what should i do?????
