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!.
