Consumer Description

SINCE DAY 1 OF PURCHASING NEW,TO CURRENT DATE, THERE IS VIBRATION AT IDLE. THERE IS VIBRATION AT HIGHWAY SPEEDS OF 60 MPH PLUS. IT HAS BEEN TO THE DEALER 5 TIMES FOR TESTING. THIS IS A KNOWN PROBLEM WITH THOUSANDS OF VEHICLES. GM SAYS IT MEETS THEIR SPECIFICATIONS. THE DEALER BALANCED THE TIRES 3 TIMES, NO LUCK. THE DEALER REPLACED THE TIRES, SAME ISSUE. I AM TOLD THE VIBRATION AT IDLE IS NORMAL. THIS PROBLEM IS DISTRACTING WHEN DRIVING. I HAVE BEEN DEALING WITH GM AND THE DEALER FOR 7 MONTHS WITH NO RESOLVE.
