NHTSA Complaint #10357039 — 2005 BUICK RENDEZVOUS

I PURCHASED A 2005 BUICK RENDEZVOUS IN FEB 2006, WITH AROUND 12,700 MILES ON IT. I ALSO PURCHASED THE EXTENDED WARRANTY ON IT (THANK GOD) AS I'VE HAD SEVERAL ISSUES GO WRONG WITH IT. MOST RECENTLY, LAST FRIDAY, I BROUGHT MY VEHICLE IN FOR A SUPPOSED ROUTINE OIL CHANGE (I PURCHASED THE LIFE-TIME OIL CHANGES ON THIS VEHICLE), SO EVERY 3 MONTH'S I BRING IT INTO THE DEALER; AFTER I MADE MY APPT. ON THE PHONE, THE VERY NEXT DAY, MY BACK WINDOW, BEHIND THE DRIVER STOPPED FUNCTIONING (ALL POWER WINDOWS); I ALSO HAD, WHAT I BELIEVED TO BE OIL SITTING ON MY GARAGE FLOOR. I HAD A CRANKSHAFT SEAL REPLACED IN JULY, SO I KNEW I SHOULDN'T BE SEEING OIL ON MY FLOOR. BY THE TIME I BROUGHT IT IN ON FRIDAY, I HAD A LIST OF THINGS I WANTED THEM TO KNOW ABOUT, ESPECIALLY AN AWFUL WHINING, SQUEALING NOISE EVERY TIME I MADE A CORNER. SO, THEY DECIDED WITH ALL OF THESE THINGS TO BE DONE, AND CHECKED, THEY WOULD GIVE ME A LOANER CAR AND KEEP MY BUICK. YESTERDAY, 9/21/2010 I GET A CALL FROM THE DEALER TELLING ME THAT THERE IS ABOUT $7,000 WORTH OF WORK TO BE DONE!! MY POWER STEERING PUMP WAS SHOT, THE ELECTRICAL NEEDED TO BE REPLACED IN THAT WINDOW, AND THE LOUD, OBNOXIOUS NOISE I WAS HEARING WHILE TURNING WAS THE DIFFERENTIAL, GONE, SHOT! MY VEHICLE ONLY HAS 40,000 MILES ON IT!! I USED TO HAVE ALL THE FAITH IN BUICKS; MY FATHER USED TO TRUST THEM 100%, AS I DID, BUT NOW? I'M THINKING THEY SHOULD STICK TO JUST CARS! MY BUICK CENTURY ROCKED! I LOVED IT, BUT THESE AWD SUV'S SEEM TO BE OVER THEIR HEADS!
