I own a late 2016 disco sport HSE. Unfortunately I experienced my first major safety critical issue with my disco sport this week. I just shut the passenger door, got in to the drivers seat and drove off, but whilst turning the second corner (onto the motorway) my passenger door flung open! I could’ve killed a cyclist. I grabbed the door and was unable to secure, the car door open alert also signalling. Once I managed to stop and inspect the door I realised all 3 bolts were missing from the door latch fitting on the door itself and so the lock had fallen inside the door. This was frightening for me as I usually have my kids in the car. I just had my Takata airbags replaced during my first service a few months but the LR service team assured me it was unrelated. Whilst LR repaired the issue under warranty I was really concerned with this as they did not have an answer as to the cause of failure. This is safety critical so I wanted to post it here - check all your car door bolts people!
