NHTSA Complaint #11601365 — 2023 TESLA MODEL Y

In May 2023, after I took my car from the Tesla service center in Santa Ana, I realized there was an issue of shaking and shredding from the motor, and it got worse when I pressed the brakes. That happened when I drove the car down a steep road from [XXX] down to [XXX] in the city of Laguna Beach; Then I drove the car to a different road from [XXX] , then down from [XXX] to [XXX] and [XXX] , where it is down steep as well. Then the same issue showed up, and I couldn't keep pressing break because the shaking got worse, so I let the car roll with shaking till it reached the straight road and stopped. Since then, I have started to avoid steeping, but once, it showed up on another downhill street, which was not as steep as the others. Still, it was a longer downhill, coming from [XXX] down to [XXX] till it splits to [XXX] and [XXX] . At that time, I did not have time to take it to the service because I was very disappointed with them after taking it for several issues several times. They never fixed them, and because I had my mother, who was in critical health issues, I needed to be with her all the time and take her to her appointments for her surgeries and wound care for several months until this year in March. Then I realized that the issue keeps changing from existing to disappearing to existing again. Still, instead of starting at a speed of 1 mile, it begins at 9 miles and disappears at a speed of 11 - 12 miles. It does not have a high level of shaking, but it still exists. I am unsure if that changes with the different updates they do through the air for the car. But the issue still exists, and the shaking levels change. Lately, they have taken it seriously after several attempts to report it and bring it to the service center. After nine days, they concluded that they had tried a similar car. This issue does exist, and it is normal when I have tried multiple cars, including their several demo cars at different times.
