Four problems related to car stall have been reported for the 2012 BMW 135. The most recently reported issues are listed below.
Vehicle almost stalls when accelerating from a stop. Vehicle will also surge forward when vehicle comes to a stop. Both issues are worsened when the temperature is warm outside and the air conditioning is on. Have taken vehicle to the BMW dealer several times to correct, but they never find anything wrong.
Vehicle exhibits an intermittent hesitation (like a stall) where there is an apparent total loss of power at low speeds (coasting) or from stopped. On several instances this has happened while in a left turn lane with oncoming traffic and creates a serious safety hazard. The vehicle more frequently, but not always surges in rmp without throttle input when coming to a stop. In many instances, the vehicle lurches forward and extra braking is required. This has resulted in near miss, rear end, assured clear distance issues. These two problems occur during city/residential driving including at slow speeds through school zones (a major concern). I purchased this car used, but with low mileage and encountered these issues on the day of delivery. Dealer reprogrammed an engine control module according to a BMW safety bulletin which I found online. The drive home was noticeably improved, however the conditions returned shortly there after and persist to this day.
I have brought my car into schomp BMW twice for this issue, the latest being last week telling them I believe there is a recall for my vehicle and it feels as if it will stall as I am turning a corner or stopped and begin accelerating. They showed no recall and hooked my car up to computer and no codes came back with any issues. I am really scared that my car will stall in the middle of turning in front of traffic. It has hesitated to where I have had to press the accelerator to the floor to get the car to move. I am afraid for my safety and for the safety of others. I received the official recall notice in the mail Wednesday and called schomp and told them I want it repaired immediately if that is the issue. They told me they don't have parts and that I will receive another notice and that I have to wait. I am nervous that something will happen and someone will be injured. What can I do for now?.
When driving in traffic the BMW 135i dct transmission will stall when coming to a stop. This results in a loss of power steering. Sometimes before the car stalls, the engine will rev without driver input to 2500 rpm and drop the clutch which results in a rapid acceleration if your foot is not on the brake this can be extremely dangerous. I have almost crashed the car many times as a result of this. BMW issued a technical service bulletin to dealers that can be found if you google the issue, but there is no known remedy. The car has been in and out of the dealer close to 10 times and they claim there is no issue. I believe the issue to be with software of the engine and transmission.
