As I was pulling into my assigned parking spot in my building complex. Both me and my 6yr old daughter were in the vehicle. As I was pulling into my parking spot and went to brake and put my vehicle in park- my brakes locked, gave out and the vehicle continued to proceed forward. As it proceeded forwarded, I immediately kept trying to brake- but because the vehicle is all wheel drive it accelerated forward pushing through the concrete parking bumper guard located on the floor of the parking spot. Because of the acceleration, the vehicle crashed into the storage units connected to the building structure. I immediately tried reversing and forced the car into park without braking. Thankfully my daughter was still in her car seat. It was terrifying and we were in so much panic and scared. My neighbors came to our rescue- because I was distraught knowing that we had literally just come off of the highway and that could have happened at any point with my child in the car. My insurance is able to cover the damages - but, the auto repairs do not consist of checking the brakes/malfunction. I cannot see myself staying with this vehicle and putting the safety of myself and daughter in jeopardy. I am praying that BMW takes the necessary measures to assist in addressing this

Twice on rainy days, when stopping on a hill at a traffic light, the brakes would not hold. Luckily the light changed and I did not hit the car in front of me. I brought it in with once, but nothing was "wrong". I am going to try again this week. I am afraid to drive the car in the rain.

Driving on the freeway for approximately 40-50 minutes. Take exit, cruise to off ramp light, the car is in motion and the brakes are applied. The car in motion initially responds and 3/4 of the way to the light (almost at intersection brakes fail, no brakes and the car makes a clicking noise' similar to when a battery is almost dead, but the car is on, electrical and everything seems ok except for the brakes. The ramp is at an incline (uphill a little) so the car stops. The car is partially in the intersection. Thankfully no car in front or cars crossing the intersection. The car is turned off and back on and we continue another mile to our final destination without further problems.

Causing the car to jump forward. By putting car in neutral and depressing the brake on a grade, when I had completed, I noticed the the RPM gage was at 4000 RPM with brake on. The vehicle was stationary at the time. Three times it has happened as I slowed down and it lurched forward striking obsticalls. When braking it possible to engage the gas pedal

August 19, 2017 I pulled into my driveway at a very low speed and applied the brakes to park. The car aggressively accelerated even though my foot was on the brake. The car went through my neighbors fences and it finally stopped between two garages behind my property on the next street. I could not open the doors or windows for a minute or two. I do not feel safe driving this car again.

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. 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.
