NHTSA Complaint #766986 — 2002 CHEVROLET SUBURBAN

WHILE DRIVING ON HIGHWAY, EXPERIENCED SEVERE VIBRATION X 3 TIMES. TIRES HAVE BEEN COMPUTER BALANCED LAST THURSDAY AND I TOOK SUBURBAN IN FOR A CHECK TODAY AFTER SEVERE FRONT END VIBRATION WHILE DRIVING ON HIGHWAY AT 70MPH. I COULD NOT REPRODUCE THE VIBRATION WITH THE SERVICE FORMAN IN THE CAR. THE FRONT END VIBRATION HAS STOPPED NOW WITHOUT ANY FURTHER ADJUSTMENT FROM SERVICE DEPARTMENT. I THOUGHT YOU WOULD WANT TO KNOW ABOUT THIS SITUATION SINCE IT IS A FIRESTONE TIRE THAT HAD PREVIOUSLY BEEN RECALLED LAST YEAR. MY TIRES DO NOT HAVE THE RECALLED SERIAL NUMBERS ON IT. I AM VERY PLEASED WITH TERRY CULLEN CHEVEROLET SERVICE. BUT CONCERNED ABOUT THE VIBRATION IF IT RETURNS AGAIN. COULD THIS BE A NORMAL PROCESS FOR THESE TIRES?*AK
