Phantom braking on other Model Y years

Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2025.

What this problem usually is

Phantom braking is a car that brakes hard on its own, often at highway speed, with nothing in the road ahead. About one owner in five mentions a near miss with the car behind.

What owners wrote

“I was driving with cruise control on and the car violently hit the brakes when there was no one in front of us. We have noticed this is more common when cresting a hill. This happens at least once every time we are on a road trip. This needs to be addressed. We know we are not the only person having these issues with the Tesla and the “phantom braking””

Filed Oct 3, 2023

“We were driving on a highway and suddenly we got a red steering weel image with a sharp noise and a warning message something about automatic emergency braking disable and we can't use a cruise control feature. I don't feel safe to drive. Tesla can't tell me when it will be fixed.”

Filed Nov 2, 2022

“Driving 1400 miles Santa Fe-Austin TX-Santa Fe, experienced phantom braking over 15 times. Generally happened while cruising on autopilot at 70-80 mph. Phantom braking occurred with no warning and for no apparent reason. The car suddenly jerked and lost 5-10 mph, and the autopilot went off.”

Filed Sep 24, 2022 · 1,400 miles

“The car keeps phantom braking at highway speeds when there are changes in the color of the road surface or sometimes when overtaking a slower car or truck in the right lane.”

Should you keep driving it?

This page can't tell you that. 3 of 47 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
