NHTSA Complaint #11508613 — 2022 BMW X5

High pitched squeaking noise when steering (at~800 mi) -> Inconsistent resistance (at~1,200 mi) -> Delayed Steering (at~1,600 mi). A high-pitched squeaking noise happens in steering every time driving over 15 minutes. I took it to the dealer for repair at ~1,000mi on 9/29/2022 and 10/4/2022. They confirmed the problem and recorded the noise. They said they couldn't fix the problem after some attempts. They promised the X5 is safe to drive while waiting for the parts. But the steering starts to show inconsistent resistance. On 11/9, I called the dealer, and they said BMW hasn't sent them the parts. I talked to BMW NA customer satisfaction for help. The representative said she will escalate the case, but nobody ever contacted me until I contacted them again on 1/2/2023. Then the representative told me to wait 20-25 days for their administrative review. But after 20 days, the representative suddenly told me the review required BMW engineer's inspection. I told them they're welcome to inspect the X5, but the engineer never contacted me. On 2/7, my mom experienced delayed steering, and she was terrified. We basically haven't driven the car for safety concern. Since the delayed steering happened, BMW NA suddenly changes their attitude and urges me to drive the X5 to the dealership. Should I wait for NHTSA to inspect the car? Or I can just give it to the BMW dealership?
