Transmission failure.
After owning the car for approximately 3 weeks I was comuting to NY from my residence in nh. The cars transmission was not responding well. I arrived near finchburg massachusettes when I decided to turn back home. Power and response were very inadequate. My wife called the dealership where I dropped off the car in exeter nh (not the selling dealer. . But a Buick/gm dealership that they recommended to have check it out since it was still under the manufacturer warranty. After inspection and a full diagnosis by the certified gm mechanic, he informed me that the "transmission was toast". They made a full repair by replacing the existing transmission. They believed it would have been impossible to rebuild considering the nature of the problem. Further, my wife did a through check prior to making an offer to purchase the vehicle. We knew that this model vehicle has a history of transmission problems. However serveral Buick /gm certified shops indicated that very few of these newer vehicle have transmission failue. It would be like a 1 and 4million chance. . . Well that is our luck. It happened to us.
Transmission failed. Yh.
