Having worked in the auto industry, dealers are independent businesses with varying levels of quality. My fathers newish F150 was having many electrical problems and a Ford dealership could not fix it (really they claimed nothing was wrong because maybe they caused the issue in another repair), so he eventually had to take it somewhere else and they swapped the body ecu. Dealerships are no silver bullet to fixing everything, it depends on the quality of the people who work there.
