“Vehicle stalls when accelerating from a stopped position. Several time, while stopped at an intersection with crossing traffic, I attempted to drive through the intersection but the car failed to accelerate. I tried shifting from auto to manual but the car still failed to accelerate for at least 5 seconds at which time it jolted forward. The issue started at around the 50k mile mark 3 years ago and continues still today (~90k miles). …”
NHTSA complaint #11402494, filed 2021-03, 55,000 miles“I was stopped at a traffic light so when the light turned green for the left turn I turned onto the middle lane of a 6 lane highway and started to accelerate when suddenly there was a vibration and the suspension light came on so I slowed down and moved to the far right lane where I noticed I had no acceleration. I limped into a parking lot and the car seemed to be vibrating and running rough so I shut it down and walked home. After towing it to Bmw of daytona I got the news that I blew a charge pipe. …”
NHTSA complaint #11121857, filed 2018-08, 44,000 miles“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. …”
NHTSA complaint #10598161, filed 2014-06, 33,000 miles“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.”
NHTSA complaint #11222668, filed 2019-06, 56,000 miles“Vehicle stalls when more than 1/8 throttle is applied, vehicle has difficulty starting. Check engine light comes on when applying small throttle inputs. The 4 previous years of this vehicle make and model, the high pressure fuel pump has had a known problem which resulted in a class action lawsuit that adjusted the warranty period for the four previous model years up to 120k miles. Bmw made slight changes to the engine for the next model years, but left the exact same part that resulted in the original lawsuit settlement. That part is the point that failed on my vehicle. …”
