RicedMr2 Posted March 27, 2022 Share Posted March 27, 2022 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. Quote Link to comment Share on other sites More sharing options...
Lexus Owners Club Posted March 28, 2022 Share Posted March 28, 2022 It sounds like an ADAS sensor which is sensing a crash and applying the brakes. Quote Link to comment Share on other sites More sharing options...
RicedMr2 Posted March 28, 2022 Author Share Posted March 28, 2022 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. 1 Quote Link to comment Share on other sites More sharing options...
Lexus Owners Club Posted March 30, 2022 Share Posted March 30, 2022 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 Quote Link to comment Share on other sites More sharing options...
RicedMr2 Posted March 30, 2022 Author Share Posted March 30, 2022 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.

RicedMr2 Posted April 10, 2022 Author Share Posted April 10, 2022 Minor update. Much more consistent today. So much so that with ign off the abs unit was trying to apply brakes. Quote Link to comment Share on other sites More sharing options...
