BOUGHT A USED 2002 RENDEZVOUS IN DECEMBER OF LAST YEAR. FIRST MONTH OF OWNERSHIP, OIL LIGHT ON. TOOK TO PENNZOIL. OIL CHANGED. TWO WEEKS LATER, LOW OIL LIGHT ON. TOOK BACK. LOW ON OIL. TOOK TO GARAGE, SAYS IT'S LEAKING FROM AROUND THE TRASNSFER CASE (THEY THINK) AND CAN'T FIX IT. NOW BIG PROBLEM: TRAVELING TO AN APPOINTMENT. HAD JUST FILLED GAS TANK ABOUT 30 MILES BEFORE, LOW FUEL LIGHT CAME ON. FUEL GAUGE WENT TO EMPTY. STARTED SURGING AND IDLING SO FAST IT COULD DRIVE ITSELF. JUST QUIT AT 60 MILES AN HOUR IN THE MIDDLE OF THE ROAD. CAUSED A SLIGHT FENDER BENDER, BUT NO ONE WAS HURT. EVERYONE AGREED IT WAS OK NOT TO CALL THE POLICE FOR A REPORT. (MISTAKE) CALLED ONSTAR. THEY SAID SOMETHING ABOUT A RELAY GETTING TOO HOT, PROBABLY CAUSING PART OF THE PROBLEM, BUT NOT ALL OF IT. HAD IT CHECKED OUT BY A MECHANIC FRIEND. RELATED HE HAD NO IDEA WHAT IS CAUSING THE PROBLEM. HUSBAND TOOK IT OUT A FEW DAYS LATER TO SEE IF IT WAS ACTING ANY BETTER, DROVE JUST FINE AND THEN DID THE SAME THING. QUIT IN THE MIDDLE OF THE ROAD. WILL HAVE TO TAKE IT TO THE DEALERSHIP, BUT HAVE NO MONEY. STRETCHED OUR BUDGET TO BUY RELIABLE TRANSPORTATION FOR OUR FAMILY. WAS TOLD BUICK WAS A RELIABLE AUTOMOBILE. HAS TURNED OUT TO BE THE WORST WE'VE EVER OWNED. ALSO, HAVE HAD TO HAVE THE WHEEL BEARINGS CHANGED TWICE, AND WE'VE ONLY HAD IT SINCE DECEMBER. MECHANIC SAYS IT'S A CHRONIC PROBLEM WITH RENDEZVOUS. THE ONES WE GOT TO REPLACE THE BAD ONES WERE EVEN BAD. HAVE NO IDEA
