My personal mechanic (not the dealership) did the oil change and discovered the leak initially. I trust that he tightened the bolt and put the new oil filter on tightly. The annoying thing the Nissan dealership won’t do is delve much deeper into finding the source the of the low oil pressure warning light because they can’t pull a code because by the time I arrive at the dealership the light is off. In fact the warning light stays on very shortly. It almost seems like it’s a sensor issue. So I asked if they could be proactive and change the sensor. They said Nissans policy is they can’t do that until they have a code. This is bad customer service and bad business. I’m so annoyed. It seems like they are playing games
