I have a 2008 Mazda Trbute with about 23,000 miles. Twice in the past three months or so I have I applied the brakes to go into a left curve. When I took my foot off the brake and started to accelerate the car began to buck like the brakes were stuck. I have the car at the dealers right now and they called back and said they ran all the diagnostics on the car and nothing is wrong. What could be causing this problem? With the most recent experience, I was going a moderate speed and there was a car behind me when my vehicle decided not to continue going forward! It makes me very nervous to drive the car again since they say there is nothing wrong with it.
