hello all  ,  here is the problem ,  two weeks after buying our lexus ux 200 f sport i decided to install a towbar  which are available thru dealers . however i discovered SHOCK / HORROR that before installation the REAR KICK SENSOR has to be PERMANENTLY de activated and relocated  [ no big deal ]  i have rang high and low and get the same answer from LEXUS    ie   rear kick sensor cant be relocated  whilst towbar is installed ,therefore one of the features that attracted wife to car in the first place  is LOST  !!!!   WIFE not happy with that . has anyone encountered this prob  ???   thx   les     p/s towbar is genuine and rated @  750 kgs
