I was driving with my family in our new 2016 buick enclave when I went to pass someone on a city street and the engine went into full acceleration. I put my foot on the brakes as hard as I could but it did not stop the vehicle. I had to put it into neutral and turn off the ignition and coast to the side of the road. Luckly there weren't many cars around me at the time. I was unable to get the vehicle started right away and I notified on star sos and they notified the police. It was towed to a buick dealer where they are looking at it now. This was an extremely dangerous and frightening experience for me and my family.
