general problems of the 2012 BMW 328

I left my car in my driveway for nearly 2 months without driving it over the winter months in new england. Upon starting the car on nicer weather, my steering wheel would not move. I can drive the car in a straight direction but the steering wheel just wouldn't budge. Had a BMW dealership diagnose the issue and fingers were pointed at hitting a pothole that caused impact and therefore damaged 4 bolts holding the steering rack to the motor. However, they could not figure out how I was driving it perfectly fine before storing it for winter, and how 3 bolts was already missing and the last bolt was corroding and eventually fell off. Nice, not a mechanical issue so not BMW's responsibility. This means I was driving the car with 1 bolt holding the steering rack to the motor for an unknown period of time. The car gave no warnings whatsoever and I am lucky that the last and final bolt held together until the car was not being driven. If the last bolt gave up when the vehicle was moving, then I may not have been so lucky. Why would an impact that strong, as described by the BMW technician, not fully rip apart the bolts? why was I able to drive normally for weeks without issues? how did it not cause any other issues around the wheel or suspension and only 4 secluded bolts were affected? what would have happened if all the bolts gave up while the car was being driven? how does a BMW cannot withstand normal impact with its fine german engineering? Ford had recently recalled almost 1 million vehicles because their bolts were faulty and would corrode under water/snow with salt. Tesla did the same recall earlier this year. Please note Tesla uses the same manufacturer for these aluminum bolts which are susceptible to corrosion as BMW.

The contact owns a 2012 BMW 328i. While driving approximately 40 mph, there was a complete loss of power steering with an illumination of the power steering warning indicator. The contact applied significant force to the steering wheel in order to maneuver the wheel. The vehicle was maneuvered to the side of the road where the engine was turned off. Upon restarting, the steering wheel functioned normally with the warning indicator illuminated. The vehicle was taken to an authorized dealer for inspection where they advised the contact that the battery was low voltage. The vehicle was not repaired. The manufacturer was not notified of the problem. The approximate failure mileage was 5,000.
