Lenovo certainly has been one of the better ones for many years. But they have had models, including in the T series, where you basically had to replace a huge part of the laptop for a minor thing.
My X1C Gen 8 got a new motherboard because of a broken USB-C port. A T14 Gen 1 had to replace the complete top-part of the frame as the keyboard was glued to it - and to replace it, you had to unscrew basically every single component inside the laptop; everything was attached to this frame.
Also, the overall quality seems to have dropped after the T460 models. I've had one service on a T450 and a T460. But had 3 services on the X1C Gen8 and 2 services on the T14 Gen 1. Currently, a X1C Gen11 has behaved nicely and properly, but that's also the newest one. Issues typically occurs after 2-3 years of use.
That said, the T14 Gen7 and T16 Gen 5 improvements begins to look more like the good old T4xx series again, in regards to repairability. That's definitely a good step in the right direction. Now that just need to happen with the X and X1 series too.
