2004 Buick Rainier Owner Comments

problem #1

Rainier 6-cyl

A 2004 Buick Rainier with full time 4 whell drive and locking rear differential which my wife and I bought the last week of November has a severe safety problem. The car slides out of control on corners under the slightest acceleration when any snow is on the road. The car was brought back to the dealer twice, the secound time I was told by one of the owners of mack Pontiac, GMC, Buick in hicksville, NY, rodney gomez, that all 2004 Rainiers have the same problem because of the locking rear differential. I realy think you should look into this as it is a very dangerous situation. Thank you.
