Sadly Thinkpads no longer are what they used to be. I got the X1 Extreme Gen 5 couple of years back and have had all kinds of problems with it. Blue screens, problem with fans sometimes getting stuck at 100%, constant problems connecting to the dock, not to mention bad battery life... My coworker had to get a warranty replacement when the usb-c port stopped working without any apparent reason only after a month of use. And other coworkers with newer models are also reporting issues.
It's a damn shame too. I love my T530 so I got a T460 and it is so shite. Although I did get unlucky with a cracked mobo but still. Even the x260 I have feels slower than my 530
