Outside door handles loose and falling off. They feel cheap and are only glued on?!? Problem started in rear door where child gets in and out, but now happened in 3 out of the 4 doors.

Interior driver door handle broke off. I replaced it myself with a kit from ebay.
My outer drivers door handle broke and I waited as long as possible to get this fixed. It costed about $120.00 and than about 1 wk later after I got it fixed the inside drivers door handle broke. This costed me $350.00!!! Absolutely ridiculous!!
