“I just purchased z4. Did not notice any problem during test ride. On my way home during purchase steering became an issue. The car would be driving fine then what I would a dead spot would appear. The steering wheel will suddenly shift left or right what seems a few inches. This causes driver (me) to compensate to avoid going in ditch or crossing a lane or getting into an accident. This happened many times on my 70-mile trip home.”Owner report · Steering · Apr 2021
