I just noticed this evening that there is a bar on the underside of my 2012 Prius v which runs across the width of the car just in front of the rear wheels. The reason I noticed it is because one side of this bar was hanging loosely just inches above the pavement! I stuck my head under the car and could clearly see that bolts were missing. The side which was still attached had 2 bolts (remaining)... both of which had worked themselves quite loose. I have tightened them down and applied nylon tiestraps to both sides of the bar to hold it in place until I find replacement bolts... preferably to be replaced by Toyota service. The car has only 5000 miles on it and was recently in for regular service at a Toyota dealer. I am completely shocked to find bolts on the underside of this new car coming off! Had this bar come off at highway speeds, it could have caused a serious accident for those behind me. Unbelievable. Has anyone here experienced the same problem with a 2012 Prius v? Can someone explain to me what this bar is? (it appears to simply bolt to the undercarriage, so I assume it is just there to deflect obstacles from hitting cables, etc.) If you don't have this bar on your Prius v... perhaps you've already lost it on the road somewhere. Yikes. Toyota service is getting a call first thing in the morning... I wonder what else is destined to start falling of my "reliable" family car? It is somewhat ironic that I just had a discussion with my wife earlier in the day that I might be in need of a new socket set for the garage. Perhaps I should send it to Toyota.
