Manufacturers want their dealerships to be the ONLY one allowed with access to repair their cars- yet the dealerships no longer have techs that can diagnose. When a car gets beyond 5 years old corrosion and age mandate the ability to track down and troubleshoot. Instead they fire the parts cannon and make the customer pay knowing very well the root cause may not have been identified and fixed.
Yep this.
Their hope is that if your service experience is bad enough, you will just say "the heck with it" and trade it in on a new one.
Last year I dealt with a dealership--the young tech was in over his head. They wanted to throw $3500 worth of parts at it. About an hour on Google and Youtube and I fixed it myself with a $30 sensor and about 2 hours of my time.
