I noticed that every time I drive my LR Disco 1996 by a rough road o bumpy road the Hazard lights turn on and the doors locks get up. The only way to turn it off is turning off the ignition and turning it on again; because is a manual trans. Few days ago is more frequent after I change to new tires Firestone AT. I know how to deal when its happen, but is a little disconforting when you are not alone in the vehicle. Do anayone can give me a hint how to fix it.......please !! Gracias (Thank you) !
