“On saturday 8/8/15, I was parking my Bmw 335I car to get groceries, and while entering the parking spot, the engine began racing out of control. I hit the brakes hard, but the car would not stop. I tried to shift into neutral, but the shift control was locked in drive and would not move. Lastly I finally hit the stop engine button, and the car finally stopped, but not after I had bumped into the car in front of me in my parking space. …”

“My 2012 Bmw 335I couple m sport package (automatic) engine stalls randomly (5 times since purchasing the car in november of 2013). As a result, the power steering fails and power brake assist also fails. Resulting in some scary situations indeed. This typically happens between 5-40 MPH. Engine typically restarts after 10-15 min. The last time this has happened was on 5/21/14 at around 9am pst. I was stranded on ca highway 85. Vehicle has only 7k miles. No engine fault codes register when taken to dealership and they send me back telling me that the car is safe to drive. …”

“on my car there is what is called the bowden cable that works to open and release the hood so that it can be opened. The problem with the design of the cable is that it sits right over a coolant hose leading to the engine. What happens is that the coolant hose gets very hot and the bowden cable that sits right over it melts along with the coolant hose. I just noticed this and felt it is a huge problem that could cause the coolant hose to either burst over time.”

“The contact owns a 2012 Bmw 335I. The contact stated that there was an abnormal noise emitting from the vehicle and suddenly it stalled. The vehicle was taken to an independent mechanic where it was diagnosed that the vanos bolts were loose and fractured. The vehicle was not repaired due to it not being included in NHTSA campaign number 14v176000 (engine and engine cooling). The manufacturer was notified of the failure and confirmed that the vehicle was not included in the recall. The approximate failure mileage was 69,000.”
