I worked for a major auto manufacturer for 24 years--closely with all facets of dealerships including parts and service.
Only time any dealership sees any of my vehicles is when the factory's picking up the tab. The manufacturers have given dealerships a license to steal when it comes to parts and service--especially with their maintenance packages. No thanks.
My last 600k miles driven on new cars have been without any warranty work being conducted.
Unfortunately, Chrysler engineered an oil filter just for the 3.0 diesel. That's a rarity in the auto world. $60 list price--$43.92 online. And outside filter companies have not come up with a replacement yet. Sorry about that.
