Problem: Tesla, Inc. (Tesla) is recalling certain 2019-2021 Model 3 and 2020-2021 Model Y vehicles. The brake caliper bolts may be loose, allowing the brake caliper to separate and contact the wheel rim.
Risk: Contact with the rim may cause a loss of tire pressure, increasing the risk of a crash.
Fix: Tesla Service will inspect and tighten, or replace the caliper bolts as necessary, free of charge. Owner notification letters were mailed July 23, 2021.

Phantom brake incident today,5/26/26. Traveling 35mph, brakes slammed on for no apparent reason. Seatbelt tightened and my head launched forward. Neck is very strained.
I was entering the on-ramp to [XXX] , from [XXX] , to merge onto the freeway east bound towards [XXX] , when my Tesla suddenly lost all power, the brakes did not work and the power steering completely failed making it feel like it was locked up. I was traveling approximately 40-50 mph at the time…
When driving with cruise control engaged the car randomly brakes and shows a "curvature assist " indication. The car quickly slows from 55 to 35 with no warning. This primary happens on a straight road, not a curve. I am concerned about the traffic behind me.
