My 2019 BMW X1 with 21k miles is still under warranty. It developed excessive play in the steering wheel. The dealer has tried to fix it in conjunction with BMW of North America for almost 5 months without success. The dealer now points to BMW corporate and corporate is ghosting me. This appears to be a clear breach of contract. Has anybody had an experience with this steering issue or another issue under warranty that BMW could not fix? What's an owner to do?
