2017 BMW X3 brakes complaints

Filed Jan 28, 2017 · Brakes, Driver assistance · 600 miles · CA · crash

I was stopping my car at a red signal behind another vehicle. I applied breaks and vehicle reached to complete stop. Immediately, engine picked up and started moving forward even though breaks are completely pressed. I had to do something to stop the car rear ending. So, I released and re-applied breaks. Vehicle reached complete stop and again started accelerating forward. I repeated the process but the third time it hit the car infront of me. The car is equipped with : auto start/stop engine (which stops the engine when the car is at complete rest). Auto hold (which allows the driver to take the foot off of the break) both the functionality are turned on when the incident happened, but I didnt take off my foot from the break pedal. Also, AC was running. I found another driver complaining the same online. Http://www.bimmerfest.com/forums/archive/index.php/t-766433.html

During my normal city driving route the brakes started making an awful screeching noise. I pulled over within 1 city block of hearing the noise and my rear disc brake rotor had a large groove worn into it. The dealership said there was a rock that got stuck between the pad and the rotor and they would repair the car for free, which included ordering parts. I thought it was strange when I called the dealership & the clerk that answered the phone said that this happens often, so they just repair it for free. I asked if it was a defect in the design, they assured me it wasn't but it makes me question how often this happens and what is the accident rate associated with this issue. I've never had a vehicle get a rock lodged between the rotor and pad. The specs for the space between the two are typically micrometers. I bought the vehicle brand new less than one week ago.
