NHTSA Complaint #11512924 — 2023 TESLA MODEL Y

This is the second instance of this issue happening, first at 1800 miles ODO, and second at 4690. Both instances, when driving, the vehicle suddenly and violently shuddered to a stop. The first instance happened as I pulled out from a stop sign to take an unprotected left onto a street. In the middle of the intersection, the car shuddered to a stop violently and a lot of warnings and alerts came up on screen. Cars moving both directions had to suddenly stop to not hit my car dead in the intersection. The gear stalk inputs to put the car in drive or reverse and allow function of the vehicle did not work. I pushed the park button on the right stalk and then moved it into drive, which it allowed. I was then able to limp the car out of the intersection (with power vastly reduced and speed reduced) and await a tow. The second instance I had pulled into a parking lot at around the same speed (~15 mph) in which the car again shuddered violently to a stop with no ability to override. Traffic behind me had to brake as to not hit my vehicle which stopped in the middle of the lot. Again the car was inoperable until this time locking and unlocking the car from outside of it and reentering to limp it to a parking spot for tow. Safety of myself and others were put severely at risk suddenly and without warning from the car stopping itself. If this were to happen in other, less fortunate scenarios, risk to human lives is great. Problem has been confirmed by Tesla service center, but not reproduced while in their possession. The vehicle was inspected by Tesla service after the first incident and was explained to have found no faults with any hardware, but found a corrupt line of code in the firmware (no update or firmware change was noted to be available). Warning messages and alerts populated at time of incident and no sooner (no warning is given prior to issue). Alerts include power reduced, rear motor disabled, vehicle shutting down, automatic emergency braking disabled and more.
