The engine on my 2009 Enclave was replaced in Feb of 2012 because it was cracked , at the time I had approximately 32k on the car. There was no indication of a problem the car just died on a major highway. The car again died a few weeks later due to a timing belt snapping. On 8/10/12 I was traveling from my home state of new york to virginia for vacation, with my family, and the car lost power again on a major highway at 10:30 at night we had to have the car towed, find a hotel and then rent a car to get to our destination. This time it was a fuel injector and an O2 sensor. We have incurred over $900. 00 in expenses we have contacted Buick and they are not willing to do anything about this car. We will no longer be covered by a warranty after 50k the car currently has about 43k. The car has broken down 3 times since Feb. Each time with my family in it, there is never any indication that the car is going to break down it just dies. I am fearful to keep putting my family in this car what do I do?.
