I am in the middle of a deal to purchse a new Kia Sorento.I have been told by he garage that there isnt a detachable tow bar made for the Kia Sorento I know that thats nonsense but not the first porkie pie they have told me.They want to fit a standard fixed tow bar I dont have any problem with this.However, my question to this forum is will a fixed tow bar affect the rear sensors on the back of the car? I dont trust the dealer as he has been caught out telling porkie pies several times.Thank you in advance for any help you can give me.
