Example complaints

Engine: “My vehicle has 64,000 miles and I was exiting the driveway and accelerating up to 45mph when all the sudden I encountered a complete loss of power with sounded like a bang in the engine. My car immediately slowed down to under 30mph and started shaking. Luckily I was only 2 minutes from my house.

NHTSA complaint #11311609, filed 2020-02, 64,000 miles

Fuel system: “My 2014 Bmw 435xi stalls on while driving without warning. The same issue was reported on NHTSA campaign number: 15v189000 for my vehicle model and year. When I input my VIN for the recall, the fuel pump issue isn't shown. For this reason, bwm will not pay to replace the fuel pump. My girlfriend had the same issue on her 2013 Bmw 328i and Bmw replaced her fuel pump and the problem was resolved. I believe the clean point established by Bmw for this fuel pump issue wasn't correct or bad parts were still in vehicles outside of the clean point. …”

The first time I was crossing a very busy 3 lane northbound road to get to the left turn lane when without any warning the car just stopped. They was no engine light on dash. I was lucky that I was not hit as I didn't even have the opportunity to brake, to indicate to drivers behind me that I was slowing down. The lights, chassis stabilization and drivetrain malfunction came on the dash. …”
