As I posted the below in another thread at
Model 3 Trunk Issues
Yeah, it definitely takes a very hard slam to close it currently on mine.
Regarding the issues you, the OP and the videographer reported, I wonder if the force required to close the doors and trunk are actually within intended spec at the factory. Or, if it's a case of some actual production issue.
I watched a copy of this video AGES ago and as I posted elsewhere, I initially thought it was dumb to bother with this:
.
But then it occurred to me that if they didn't measure this and apply the same principles to other parts of manufacturing and quality control, an automaker could have many annoyed customers and potentially incur huge warranty costs, blowing the profit for a vehicle and/or the company. (And just as a reminder, Tesla has yet to have a single profitable year. For 2017, they lost over $2 billion and for Q4 2017 alone, it was over $670 million. This doesn't include cash burn for items such as capital expenditures.)
And those annoyances can add up and could spread by worth of mouth, social media, traditional media, etc. and lead to low customer satisfaction.
Also, note how much force the worker is using to close the door.
If you want to watch less of the video, watch about 1:20 to ~3:11 and 4:40 to 6:15. Optional: 3:11 to 4:03. And, for those watching on computers, you can always click the gear icon to adjust the playback speed.
