I am having problems a couple times a week, I get in my new Buick Enclave with 3,000 miles on it and I step on the brake and push the start button and the car won't start. Sometimes the horn honks twice when I attempt to start the car. Normally after it won't start, I take my foot off the brake, and then reapply my foot, then push the button again and the car starts, but once I had to call a tow truck. When the tow got there, the car started. I now record a video every time I start the car, and finally got a video of the car not starting, and another one of the horn honking twice. I've sent those videos to the dealer hoping it helps them find the problem. The car has been in their service department twice for a total of at least 13 days and they haven't found the problem. Its going back in to the service department again today for the third time. Has anyone else had a starting problem like this?
