'13 LS460L brakes apply on their own at any speed.

[RicedMr2]

as the title states.

I have a 2013 LS460L

The brakes randomly apply on their own at parking lot and highway speeds.

Previous to my ownership the Skid control Ecu, And the Brake actuator  for this issue.

Obviously to no avail.

It sounds like an ADAS sensor which is sensing a crash and applying the brakes.

Maybe, But I don't think My 13 has any of that.

It feels more like the Ebrake has been applied.

I have an IR temp gun in the car to see which brakes are getting hot, but it hasn't done it   since I put that in the car.

This can happen gradually with a seized caliper which stays applied and generates heat which you could easily measure with a temp gun to identify which wheel/brake it is

[RicedMr2]

it's not gradual though.  It does not appear to be just one as it does not pull to one side.

the first time it did it at parking lot speeds it was a sudden lockup of at least one wheel.

 and the first highway one when it did it the auto down shifted 3 gears like it was going up a decent hill  all of a sudden.

Minor update. Much more consistent today.

So much so that with ign off the abs unit was trying to apply brakes.
