Jul 7, 2021Transmission & drivetrainFuel system

Vehicle has stalled while in operation (at speed) 5 times since owning. All were very dangerous situations for my wife and surrounding drivers. All issues were apparently "fuel system" related. I purchased this vehicle on May 11, 2018 (POC) from Fields BMW South Orlando, FL. The car was most recently brought in for repair for a continued issue on May 3, 2021. Vehicle has never been in a wreck and has roughly 73K miles. •5/31/2018 – Issue with fuel system. Car started shaking and would not start. 2 weeks after purchase. •6/05/2018 – Issue with fuel system. Vehicle stalls while in operation. •8/21/2018 – Vehicle is losing acceleration while driving. Drive train malfunction light comes on. •3/5/2019 – Check engine light on. Faulty tank ventilation pressure switch. •6/23/2020 – Car stalls while driving (35 mph+) and strands me in the middle of an intersection. Car will not switch out of park. Police had to come to move the vehicle. Very dangerous situation. Wife is driving, 3 months pregnant at this time. •8/15/2020 – Car stalls while driving. Again, driving around 30+ mph. Wife had to quickly pull the car to the median. Dangerous situation. Car will not switch out of park. Wife is driving, 5 months pregnant. •5/3/2021 – Car stalls while driving. Luckily able to coast into a gas station under no power. Car will not switch out of park. Wife stranded with no AC with 3-month-old baby and 9 yr. old daughter. - 5/17/2021 - Transfer Case Needs Replacement Besides the fuel system issues, I believe there is a dangerous feature with this vehicle in that it cannot be switched out of park when it loses power. Being stuck in the middle of an intersection and unable to move a car into neutral (even with police officer) is extremely dangerous. Vehicle was inspected by a BMW TSE for transfer case issue. They say it needs to be replaced. This vehicle is a danger and should not be on the road.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2016 BMW X4 verdict →
