Rear hatch handle on 2004 Scion Xb continues to break off. Had it replaced June 5 2009 and it broke off again March 2012. The engineering and materials are defective.
The rear door latch handle broke off in my hand after trying to open the rear door about 18 months ago. I replaced the part at the dealership at a cost of almost $300. This happened again in Nov. 2012. It is a high stress part that is held on by 2 very small cheap plastic brackets.
