This is strange and probably doesn't happen too often. Two handles on my car have broken off. A couple a weeks ago the passenger one broke off, and two days ago the driver's came off in my spouse's hand. The "chrome" handles, are plastic, and we think the heat over time has worn them out, though we never had a car have its handles fall off. We send my daughter in to unlock the door from the opposite side and to give it a push open.
Before she has to crawl in through the back hatch, I'm getting the driver's door fixed next week, and then one every couple of weeks, because each plastic handle is 100 and another 100 each to install. We went with a body shop, because their estimates were less than the dealers'. I'm so thankful that the car runs.
