NHTSA Complaint #10194086 — 2005 CHEVROLET AVEO

I HAVE TAKEN MY CAR IN SEVERAL TIMES TO SEE WHY THERE IS SUCH A BAD SHAKING WHEN I REACH SPEEDS IN EXCESS OF 55 MPH AND THERE SEEMS TO BE NO REASON AFTER BALANCING MY TIRES, ON TOP OF HAVING ALL REPLACED AND ALLINING THE TIRES THERE IS A HORRIBLE SHAKING OF THE STEERING WHEEL AND A VERY LOUD NOISE LIKE A ROARING OISE IN THE BACK OF MY CAR. ALSO I HAVE A HUGE CRACK IN THE WINDSHILED THAT I THOUGHT CAME FROM A PEPPLE OR SOMETHING HITTING THE WINDSHIELD HOWEVER THERE IS NOT A DENT SO TO SPEAK OR ANY MARKS THAT WOULD INDICATE A ROCK HIT IT, THE CRACK STARTS UDER TEH RUBBER LINING AND GOES ALL THE WAY DOWN THE WINDSHIELD FROM ONE END TO THE OTHER.
