I bought this vehicle in feb. 2015. About a week after purchase I was going to work one night and the vehicle suddenly veered to the left and brakes locked. The stability light then came on. I pulled over and shut the van off and restarted it . No light was on then. About one month later it did it again. This time I was going about 50 miles ph. A car behind me almost hit me from behind due to the sudden stop.another month went by before it started doing it again. This time it veered into the path of a semi tractor trailer. I then called the dealership and they agreed to have it fixed. I got it back a week later and it still has the same issue. This problem is going to cause a major accident and hopefully no one gets killed!!!!!! Buick needs to recall these vans immediately.
