BACK OVER PREVENTION: WARNINGS, ELECTRICAL SYSTEM
I am submitting a safety complaint regarding my 2016 BMW 435i. My vehicle experienced a sudden water pump failure while I was driving on the freeway. Without warning, the vehicle immediately entered “limp mode,” causing a sudden and dangerous loss of power in active traffic. This created a serious safety hazard because surrounding vehicles had to quickly avoid my car to prevent a collision. I am aware that there is an existing recall and/or known issue involving electric water pump failures on certain BMW vehicles, including similar 2016 BMW models, but my VIN does not qualify for recall coverage despite experiencing the exact same failure and safety-related symptoms. I believe this defect should be investigated further because it creates a substantial risk to driver and public safety when the vehicle suddenly loses power at highway speeds. Additionally, my vehicle has an ongoing issue with the parking collision warning/driver assistance system. The system will randomly trigger collision warnings and emergency alerts even when I am driving safely with no obstacles or vehicles in front of me. These false warnings are distracting and could potentially cause unsafe driver reactions or unnecessary braking events. I request that NHTSA investigate both issues: 1. Sudden electric water pump failure causing immediate limp mode and loss of power while driving. 2. Malfunctioning collision warning system producing false collision alerts without hazards present. These issues present significant safety concerns and appear consistent with known defects affecting similar BMW vehicles. Vehicle Information: * Year: 2016 * Make: BMW * Model: 435iThe I would like to mention I am an active first responder (EMT) and would recommend addressing these safety concerns

POWER TRAIN
I WAS DRIVING MY VEHICLE IN DALLAS, TX AND MULTIPLE TIMES THE CAR ENGINE & ALL POWER SHUT OFF, AND THE CAR SHIFTED ITSELF INTO NEUTRAL. I SUSPECT THERE IS AN ISSUE WITH THE AUTO STOP/START FEATURE OR SOMETHING MORE. A CAR SHOULD NEVER SHIFT ITSELF INTO REVERSE WHEN YOU ARE DRIVING. BOTH TIMES ALMOST CAUSED AN ACCIDENT ON THE FREEWAY AS THE CAR CAME TO A SUDDEN HALT AND I HAD NO CONTROL WITH IT SHIFTING INTO N. THE BMW DEALERSHIP & BMW ARE CLAIMING NOTHING IS WRONG. I DO NOT FEEL COMFORTABLE ACCEPTING THIS VEHICLE BACK UNTIL THIS ISSUE IS RESOLVED AND FEEL THE GOVERNMENT SHOULD LOOK INTO ANY ISSUE OF A VEHICLE AUTOMATICALLY SHIFTING INTO N AND POWERING DOWN WHILE DRIVING.
