One problem related to steering rack and pinion has been reported for the 2016 BMW 328. The most recently reported issues are listed below.
Vehicle has under 30,000 miles and requires a new power steering module which includes the rack and pinion steering assembly, new computer programming and wheel alignment. The factory installed power steering assembly module is turning off and back on; when off there is no power steering assistance make if very difficult to steer the car especially at slower speeds. When the power steering comes back on and the vehicle is at speed it creates a very sensitive steering wheel which causes driver to over steer the vehicle. When making a sharp turn like when turning onto another street and the power steering is out the driver has to "muscle" the steering wheel to make the turn; if during that turn the power steering assist returns this causes the driver to over steer the car either into traffic or off the road. As of 10/07/2020 the power steering assist is completely out and the vehicle is not safe to drive.
