Pros
Deep pockets of former owner (Nokia) plus current owners (BMW/Audi/Daimler) lets you get away with wasting a lot of time, effort, and resources. It takes so long to get anything done (on order of months to quarters) that there's no sense of urgency. No reason to work hard and no consequences to delivering late.
Cons
Many competing groups fighting to justify existence. A lot of "we're the most important group because..." Lack of vision. Lots of efforts still alive due to momentum versus opportunity. Confusing/overlapping roles (Business planner vs Product Owner vs Product Manager vs Program Manager? Leads vs functional managers) Organized such that a single group isn't able to deliver anything to a customer, leading to lots of completed deliverables sitting on the shelf for months, to an end customer in years. Lots of mega-processes/tools, inefficiencies that scaled. Process for the sake of process that don't really make things easier.
