NHTSA Complaint #11510127 — 2018 FORD F-150

My drivers windshield wiper arm broke 4 weeks ago in the rain because the little key popped off. The wiper hit the driver behind me and I almost got into an accident. Today my passenger windshield wiper arm broke for the same reason. The little metal key popped off. This wipers are very flawed. That little key should be welded to the wiper. It was snowing and a very little snow caused my wiper arm key to break. Now I have to buy a whole new one. This is my second arm in 2 weeks. I have now replaced both wiper arms. This could have killed me, my family and others. Corners should not be but while making wiper arms. They can cause a visual hazard and result in death. Not smart! Please do a recall on these.
