Franc I feel for you, your problems are practically identical to ours. How can GM live with the shame of screwing people out of their life's savings to keep repairing a vehicle that was supposedly a reputable 'Buick' model. I have not yet? had the rear differential, but all the other problems including rear wiper and now fan on 1,2 and 3 doesn't work. Show me any other vehicle on which this has ever happened?? uh, yes, GM Montanna!
In addition tires seem to wear funny, front outside tread is almost gone on second set of tires. We have 150,000 KM on it and have easily spent over $4K, PLUS we still owe moeny on it and found that we could buy a brand new one now for $8K less than the 1 yr old 02 we bought with 38K on it in 2003. That burns me more than anything. I think we could all write a book on the problems the RDV has. Most importantly they are common to all owners, neighbor just paid $3500 for transmission. Seems that 02 and 03 have the most problems, and GM should take some recent stock profits and reimburse us . God Willing.
