 2011 bmw z4, purchased new with approximately 7k miles. started to feel vibration when i braked around 5k mile mark.vibration lasts 1-2 seconds. happened 20 times so far. i was driving today, 7000k mile mark, and the engine failed and died. like somebody just turned it off. luckily i was on local street so i just came to a complete stop. this is very dangerous! then i restarted the car and it came back to life and ran like normal. took it to dealer and dealer said nothing was wrong. something is wrong if your car dies while you're driving!!
