THE RADIATOR'S COOLANT SYSTEM FAILED, RESULTING IN FLUID ACCUMULATION IN THE TRANSMISSION ON TWO OCCASIONS. WAS FIXED TWICE, CAUSING A TOW BY THE DEALER ON THE SECOND TIME. THE TRANSMISSION CONTINUED TO SHIFT HARD FROM FIRST TO SECOND, HAD ANOTHER DEALER LOOK AT IT, SAID IT WAS "JUNK." NOTIFIED GM, THEY DID NOTHING BECAUSE THE FIRST DEALER DIDN'T REPORT THE PROBLEM. HAD TO PAY FOR A TRANSMISSION OVERHAUL AT 70,000 MILES... VERY EXPENSIVE! THE FUEL INDICATOR HAS ALSO FAILED. THE FUEL PUMP HAS FAILED AND HAD TO BE REPLACED. THE DOOR HANDLES HAVE FALLEN OFF. THE WINDSHIELD WIPERS HAVE FAILED SEVERAL TIMES, BUT IS OVER THE 70,000 MILE LIMIT OF REPLACEMENT. ALSO HAD TO REPLACE THE MASTER CYLINDER. HMMM... MAYBE THE DEALER WAS RIGHT ABOUT BEING JUNK WITHOUT A WARRANTY. SO SAD THAT WE SPENT THOUSANDS OF DOLLARS FOR PRODUCTS LIKE THIS. *LA
