Owner report 11521077 · 2023-05-08 (May 8, 2023)
Around 5:48 pm Pacific time today, May 8, 2023, traveling westbound on Sunset Blvd (near the Drummond street intersection), the brakes suddenly engaged hard for a few seconds and then released and continued. Speed was around 35 mph and there were no obstructions around. This is the second incident of phantom braking that has occurred in 2 months. Luckily there was no car behind that could have collided into us from the sudden phantom braking.
