2000 GMC SUBURBAN Suspensionfront Problems

WE PURCHASED THIS SUBURBAN NEW. OUT OF THE DEALER'S LOT THE VEHICLE PULLED RIGHT, AND VIBRATED AT A MAGNITUDE THAT INTERFERED WITH NORMAL STEERING AT SPEEDS BETWEEN 55 AND 70 MPH. I HAVE TAKEN THIS VEHICLE BACK TO THE DEALER FIVE TIMES, COUNTING TOMORROW. THE FIRST TIME I RETURNED THE CAR A REPRESENTITIVE OF MAC HAIK TOLD ME "THE PULL (TO THE RIGHT) IS A SAFETY FEATURE". I AM IN CONTACT WITH OTHER OWNERS OF 2000 SUBURBANS WHO HAVE WORSE PROBLEMS INVOLVING THE FRONT END OF THE VEHICLE. SOME HAVE BEEN FORCED TO CHANGE TIRES DUE TO WEAR WITHIN 10,000 MILES. TOMORRPOW I WILL, AGAIN, TAKE THIS VEHICLE TO MAC HAIK CHEVROLET FOR REPAIRS. I HAVE ALSO CONTACTED THOMAS GOTTSCHALIC, EVP AND GENERAL COUNSEL ,GENERAL MOTORS, WITH DETAILS ON THIS PROBLEM. THANKS FOR YOUR HELP, BYRON DUNN*AK
