Three months after purchasing my 2017 BMW X1, the back hatch without warrant inadvertently starting closing, at one time almost closing on my just about 3 year old granddaughter. there was no movement and the key was placing remotely on a table. Soon after, while opened, it came down on my sisters hand. Then on Sept. 21, while removing groceries from the trunk, it started beeping and rapidly came down on my head and neck while I tried to hit the open button, causing a concussion and swelling on my neck. I have had to go on short term disability from work to deal with the long term effects of the concussion. I informed BMW North America immediately, had them do an inspection. Although the report was sent to me stating SIB states to replace Control Unit, Smart Opener for closing concern, BMW takes no responsibility and refused to pay to replace the unit.
