There is generally nothing very good about Cadillacs CUE system. Its touch screen infotainment system is riddled with haptic feedback, clunky design, and respectively outdated tech.
And now it appears to be the cause of a class-action lawsuit that one 2014 Cadillac ATS owner is pressing against GM.
A NHTSA technical bulletin makes the problem pretty clear.
The infotainment screen on certain Cadillac models from 2013 through 2017 are prone to cracking, bubbling, and delaminating, with the suggestion being a full replacement of the center stack.
