PROBLEMS WITH BRAKES ON 1999 PONTIAC BONNEVILLE. *MR THE VEHICLE SHIMMIED WHEN GOING ON DOWNGRADES AND WHEN USING THE BRAKES. NEW BRAKES WERE JUST INSTALLED AT AROUND 30K MILES AND THE SHOES WERE WORN ALMOST TO THE METAL. THE SHOES WERE WEARING UNEVEN BUT THE DEALER TOLD THE CONSUMER THAT THEY WOULD BE FINE. THE VEHICLE SEEMED A LITTLE BETTER, BUT THE VEHICLE STILL SHOOK AND COULD HAVE THROWN THE CONSUMER OFF OF THE HIGHWAY, BUT THE CONSUMER HELD ON TO THE STEERING WHEEL. THE NEW ROTORS WERE PLACED ON THE VEHICLE AND WAS THOUGHT TO BE THE FAULT, BUT THE PROBLEM RECURRED WHILE THE VEHICLE WAS BEING DRIVEN IN THE MOUNTAINS. *SC *JB

WHILE DRIVING 65 MPH, THE STEERING WHEEL STARTED SHAKING UNCONTROLLABLE. THE DRIVER WAS ABLE TO MAINTAIN CONTROL THE VEHICLE AND PULL OVER.

THE MECHANIC INFORMED THE DRIVER THAT THE VALVE STEM IS DEFECTED AND WILL REPLACED THE TIRE. MICHELIN MXV4 225/55HR17. *AK

IN MID MAY I HAD A AUTHORIZED PONTIAC DEALER REPLACE THE INTAKE MANIFOLD WHICH HAD RUPTURED AFTER A BACKFIRE UPON INITIAL START OF 1999 PONTIAC BONNEVILLE WITH A 3.8 L ENGINE. ON JUNE 1, 2004, I WAS NEARLY NEAR ENDED ON INTERSTATE 80 IN COUNCIL BLUFFS AS I RETRUNED FROM A TRIP BECAUSE VEHICLE LOST POWER. TOOK TO DEALER AND THEY SAID LOWER BEARING WAS GONE, MEANING A NEW ENGINE. I KNOW THERE HAVE BEEN NUMEROUS CONSUMER COMPLAINTS. IT'S MORE THAN THE COST OF A NEW ENGINE THAT I'M CONCERNED ABOUT. WITH MY NEAR INCIDENT THAT COULD HAVE RESULTED IN SERIOUS INJURY TO ME OR ANOTHER PARTY, I THINK IT'S TIME THAT GM TAKE RESPONSIBILITY FOR THESE ISSUES AND A RECALL IS GONE TO COVER THE ISSUE. *AK

WITHOUT WARNING, MY 1999 PONTIAC BONNEVILLE, EQUIPPED WITH 3.8 ENGINE, LOST POWER AND DIED. THE INTAKE PLENUM (SITTING ATOP THE ENGINE, AND PROVIDING AIR AND COOLING OF ENGINE WATER, RUPTURED AND SENT WATER INTO THE CYLINDERS, AND INTO OIL PAN.

I WAS ON VACATION DRIVING INTO A REST AREA WHEN THE CAR MADE A "THONK" SOUND AND THE TRANSMISSION JUST STOPPED. I COULD SHIFT IT INTO ANY GEAR, BUT IT WOULD NOT GO ANYWHERE. WE HAD TO PUSH THE CAR INTO THE PARKING LOT AND HAVE THE CAR TOWED TO A REPAIRMAN. WHEN THE TRANSMISSION WAS TORN DOWN, IT WAS FOUND THAT THE GEARS HAD BLOWN A PART. THE MACHANIC COULD NOT FIND A USED ONE AND IT WOULD HAVE TAKEN 4 OR 5 DAYS TO GET ONE FROM AC DELCO, SO HE REBUILT THE EXISTING PART. THE MECHANIC SAID HE HAD THREE OTHER CARS WITH THE SAME TRANSMISSION COME IN WITH THE SAME PROBLEM IN THE MONTH OF APRIL 2004 ALONE. I ONLY HAD 48,000 MILES ON THE CAR. WE WERE LUCKY WE WERE NOT ON THE OPEN ROAD WHEN THE INCIDENT HAPPENED.*AK
