general problems of the 2010 Volkswagen Tiguan

This model has a push to activate emergency brake. The emergency brake will engage without touching it whenever it wants. It has happened a few times while I was going in reverse with no notice nor does the light indicator go on. I have took it to mohegan vw dealer and they did find any problem with the vehicle . I tried to explain to them that it engages at any given time but they informed me that without a brake indicator on there was nothing they can do. I need help with this issue before it engages while I'm driving and kills me or anyone on the road.

Was waiting at a red light, on an incline, car stopped, with multiple cars ahead. Knew I would be waiting for a while for the light to change, so gently released some pressure on the brake. Car lunged forward hitting car ahead of me and each time I depressed the brake the car lunged, hitting the car in front of me three times. Stopped the frightening ordeal by depressing the brake and turning off the ignition. Caused neck and back injury, (reported by the injured, but not confirmed) of sheryl brown, driver of car I hit. Googled searched this problem and apparently others have reported lunging after braking in both Tiguan and toureg.

I purchased a new 2010 Volkswagen Tiguan I've had it in the shop 3 times going on the 4th tomorrow due to the braking system. In reverse the brakes squeal so bad, how safe is this to drive? the automobile shop is basically telling me there is not thing they can do. While I drive the call and have to apply brakes sometimes I have to punch the brake pedal all the way down to the floor for the car to stop.
