Fremont Tesla replaced the "STEERING GEAR, LHD (1070801-00-D)" on my less than 3-month-old MS after verifying that there is a rattle coming from the front of the car. After this repair, it felt like the rattle went away, but it returned in less than a day, louder than before. I took the car in for service again and I was told that this is how it is going to be since they need to work with the steering rack part supplier to get them to update the design of the part and that they will bring it up with their engineering, and I don't buy that. The rattle is pretty bad and loud and bothers me the most about this car. I wonder if other people are having this issue as well since they told me that this is a defect in a part that they don't have a fix for. I also wonder why they replaced the part on my car to begin with (and made the rattle worse) if they knew that they did not have a fix for it. A new rattle was also introduced, which doesn't bother me that much, after this service. I am getting really frustrated with my Tesla quality issues. I have been to PA and Fremont SC combined at least 5 times with 4 of them being a day or more long repairs since getting the delivery of my car during the last week of September.
