NHTSA Complaint #11459815 — 2021 TESLA MODEL Y

When driving the vehicle primarily on highways and with the Adaptive Cruise Control active, the car randomly reduces the cruise speed by up to 35 mph and then proceeds to slam the brakes. This happens intermittently on open road, 4 lane highways, with and without any traffic nearby. We logged the times that these occurred and took them to our local Tesla service center and they said “This is a software bug that we have to wait for Tesla to fix. There is no way to disable the adaptive nature of the cruise control either.” We informed them that this has been occurring for about 6 months now and they said “You’ll just have to wait until Tesla fixes the code. It gets better every release so eventually it won’t do this anymore”
