2001 Pontiac Firebird

THE FRONT ROTORS/BRAKES HAVE BEEN REPLACED 5 TIMES SINCE I GOT THE CAR. THE FIRST TIME WAS WHEN THE CAR HAD 196 MILES ON IT, AND HAVE BEEN REPLACED ABOUT EVERY 8,000 TO 12,000. THEY HAVE BEEN REPLACED ABOUT 2,000 MILES AGO AND THE FRONT END IS VIBRATING AGAIN NOW. THE CAR HAS 45,000 MILES ON IT BOUGHT AND EXTENDED WARRANTY FOR 60,000 MILES. THE LEFT FRONT TIRE HAS LOCKED UP TWO TIMES WHILE DRIVING, CAUSING THE CAR TO SPIN ACROSS FOUR LANES, THE FIRST TIME AND DOING A 180 WHILE ON AN ON RAMP RIGHT AFTER LEAVING LONG PONTIAC OF CHATTANOOGA. EVER TIME I TAKE THE CAR TO THEM THEY JUST TELL ME THAT THEY CAN NOT DUPLICATE THE PROBLEM AND TELL ME IT IS OK. *JB

WHEN CAR IS SITTING STILL AND IN PARK OR NEUTRAL THERE IS A VIBRATION THRU OUT CAR @ 2200 RPM'S. WHEN VEHICLE IS IN DRIVE THE VIBRATION OCCURS AT 48-51 MPH. THIS VIBRATION IS WORSE WHEN THE VEHICLE IS IN MOTION. TWO DIFFERENT DEALERSHIPS SAY THIS IS A "NORMAL CHARACTERISTIC" OF THIS CAR. BOTH DEALERSHIPS HAVE AGREED THERE IS A VIBRATION BUT SAY "THEY CAN DO NOTHING ABOUT IT". THEY HAVE ALSO SAID THAT SOME OF THESE CARS VIBRATIONS ARE WORSE THAN MINE.

WHEN COMING TO A STOP, APPLIED BRAKES AND VEHICLE PULLS FROM LEFT OR RIGHT. VEHICLE HAS BEEN REPAIRED, BUT PROBLEM STILL EXISTS. DEALER CONTACTED. *AKALIGNMENT AND BALANCING OF TIRES HAS BEEN PERFORMED MANY TIMES ON THIS VEHICLE. CALIPERS, ROTORS, BRAKE HOSES, RACK AND PINION AND STEERING RACK HAVE ALL BEEN REPLACED AND PROBLEM WITH VEHICLE PULLING IS STILL PREVALENT. *JG

THROTTLE STUCK WIDE OPEN I HAD TO DEPRESS THE CLUTCH AND TURN THE ENGINE OFF. THIS HAS H APPENED FIVE OTHER TIMES AT VARIOUS SPEEDS AND UNDER DIFFERENT WEATHER CONDITIONS. GM KNOW OF THIS PROBLEM IT HAS CAUSED ACCIDENTS AND THEY REFER YOU TO THE DEALER. THEIR DEALERS DO NOT HAVE A FIX FOR THIS PROBLEM AND THEY KNOW THIS INFORMATION. THIS PROBLEM IS SHOWING UP IN ALL F-BODY GM CARS WITH THEIR 5.7 LITER V8S. I HAVE NOT REPORTED THIS PROBLEM TO MY DEALER BECAUSE I KNOW THEY CAN NOT FIX IT. THIS IS A PROBLEM THAT IS NOT CONSISTANT. IT DOES NOT HAPPEN IF YOU PREFORM A GIVEN TASK. ONCE I STARTED MY CAR AFTER IT WAS SITTING ALL DAY THE TACH RACED FROM 900 RPM TO 4,000 RPM. I SHUT THE ENGINE DOWN AND RESTARTED THREE TIMES BEFORE THE PROBLEM WAS CORRECTED. ONCE, I WAS EXITING I-96 FREEWAY AT ORCHARD LAKE ROAD EXIT I HAD BEEN DRIVING AT 70 MPH WITH THE CRUISE CONTROL ON. WHEN I APPLIED THE BRAKES TO TO SLOW FOR THE EXIT THE ENGINE SHOT UP TO 5,000 RPM FROM 2,100 AND THE CAR WENT FROM 70MPH TO 90MPH BEFORE I PUT THE CLUTCH IN AND APPLIED THE BREAKS. ANOTHER TIME I WAS DRIVING ON NORTH BOUND TELEGRATH ROAD BETWEEN 14 & 15 MILE ROADS AT 50 MPH IT WAS SUMMER TIME AND I HAD THE AIR CONDITIONING ON. I APPLIED THE BREAKS TO SLOW DOWN AND THE ENGINE AGAIN WENT FROM 1,800 RPM TO OVER 4,000 RPM. I AGAIN PUT IN THE CLUTCH, AND REMEMBERED THAT I HAD READ A POST ABOUT THIS PROBLEM ON THE INTERNET, SO I TURNED OFF THE AIR CONDITIONING AND THE ENGINE WENT BACK TO NORMAL. THIS IS A VERY SERIOUS PROBLEM, SOMEONE IS GOING TO BE HURT OR KILLED. IF YOU GO TO THE SLP ENGINEERING WEB SITE (HTTP://WWW.SLPENG.COM) YOU WILL FIND THAT THERE HAVE ALREADY BEEN ACCIDENTS CAUSED BY THIS PROBLEM. I BELIEVE THAT THERE IS EITHER A DEFFECT IN THE PCM OR IN THE WIRING HARNES THAT CONTROLS THE FUEL INJECTION SYSTEM. TAKING THE CAR TO A DEALER WILL NOT BE OF ANY HELP. THIS IS AN ENGINEERING PROBLEM. PLEASE HELP US! THANK YOU, [XXX]. *AK INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *JS
