It's all part of built in redundancy.
The car makers want you to buy a new car rather than fix the one you have so they actually design them to be "difficult".
The dealership workshop is usually a shop of horrors with bits often left off a car after it's repaired.
Or how many times have you heard of a friend having major problems getting their car fixed at a dealership?
It seems to be the standard thing... The story starts with "I took my car to the dealership and guess what..."
Things will only get worse from now on.
"Cheap Cheap" seems to be the in thing.
