I was on the highway with no use of my gas pedal, which resulted in me rolling back all while being 5 months pregnant. June 18,2024, at 3:04pm ,my vehicle broke down again due to the same message that previously popped up “Drivetrain malfunction”.

“On Aednesday April 12th, I was driving on a busy road and the car died. There was no safe place for me to pull off which had cars swerving to miss me. There was no indication of coolant level low. The car just died. After extensive research, I found out this car was part of a service action that was never performed because I wasn’t notified of it. This is very dangerous to anyone who owns a 2019 BMW 430i and will cause bodily harm or death if not recalled.”

NHTSA complaint #11518866, filed 2023-04

“Car stalled because of coolant vent line in cylinder head Faulty coolant line like other models. I was lucky enough to get out of traffic without an accident. This car had to be flatbeded to dealership to repair their “service advisory” which I was never notified of. My papers from dealership says BMW recall and they are now refusing payment for tow!! This faulty part could cause someone to be killed!!! They need to be held accountable for tow because of a faulty part that could be deadly”

“The vehicle had previously undergone front-end collision repairs. Seventeen days after retrieving the vehicle, it suffered a sudden, catastrophic loss of engine coolant while driving. The dashboard flashed an 'Engine Temperature High' warning followed immediately by an 'Engine Overheated' warning. Due to immediate road conditions, the vehicle could not be safely pulled over or stopped right away, creating a severe safety hazard. The vehicle became completely undrivable and was towed. …”
