The main issue was a catastrophic failure of the VC_FRONT module which is one of the critical onboard computers that manages things like the 12v battery and low voltage power distribution (basically a "smart" fuse box). Without it the car is bricked and cannot be driven.
That took several weeks and some back and forth around the extended warranty to resolve, and then even after that module was replaced, on my first drive after the repair it went straight into limp mode and then spent another week at the service centre having that diagnosed.
During this time I decided it might be time to start looking for a new car, ended up selling it a few months later and took delivery of a new Polestar 2.
No shit. Chess programs are specifically built and optimised to the nth degree for this specific use case and nothing else. They do not share the massive compute overhead and convoluted nondeterministic nature of an LLM.
This is like drag racing an F1 car and a Camry and being surprised at the result.
