Had the towbar fitted by Mitsubishi at Portbury before being delivered to the dealer. When I got the car home I removed the detachable towball and tried to insert the plastic blanking plug into the recess but it fouled the lower rear bumper. I also noticed the towbar is hard up against the bumper and has distorted the bumper to a noticeable amount. I took the car into the dealer today to have this problem rectified only to be told that there is nothing they can do to fix the problem. Apparently in the instructions for the towbar it states that some deformation of the rear bumper will take place. The dealer has suggested trying to cut down the blanking plug, but this then will not be so secure and could fall out, or to cut a piece out of the rear bumper. Incredible that on a modern car they could get this so wrong. Has anyone else noticed the same issue or are aware of any fixes for this problem?
