Both outside door handles on left driver side and back passenger side have fallen apart when opened. Each occurrences has happened at different times. About a year apart. My concern is what if there was an accident with children in the back seat and I was unable to open the door. Same with the driver side. I have been driving 65 years and never had door handles fall apart. (more cheap quality we pay for). This can't be happening to just me!!

From approx. 60,000 miles drivers door would stick in the locked position regardless of lock solenoid actuation. Cycling door lock solenoid several to "many" times usually loosened it up, however, at 80,000 miles it stuck for 3 days. Dealer that replaced the mechanism advised that when the door unlocks, there is a metal gear in the door lock mechanism that engages a plastic gear that moves to engage the door handles (in & out) so when you pull on either handle the door opens. So, when the plastic gear wears out, your done. Dealer had to break into the car because the door will not open with this malfunction. Drivers door, passenger door and now, last week at 180,000 miles the rear driver side door have all malfunctioned and needed replacement. Approx. $250 - $300 each time depending on need to break in. Safety issue if you get locked in when it malfunctions.

On a cold morning in february, outside driver's side door handle broke off during normal opening function. Upon further investigation, it turns out that the entire handle is merely chrome-plated plastic, with pem nuts inserted into the rear side of the handle. The entire tensile load of the handle is carried on these two points, and this is where the plastic fractured. Having no luck finding replacement parts, and no reason to believe that putting a similarly-designed handle would prevent the problem from recurring, I repaired the handle by drilling through the handle and putting 2 bolts and 2 nuts through the body of the handle to secure it to the door.
