My in-laws have a 2019 Pilot that has always been dealer serviced. Today I noticed oil spots on their driveway then I go to their garage and notice the spots coincide with the rear differential of their car. My in-laws had their diff serviced back in April. I crawl under the car and the fill plug is finger tight and dripping. Thankfully the drain plug was good and tight. This is the second incident with the same dealer. Last time it was the oil plug that was dripping after an oil change. This kind of service at a dealer nonetheless. I said next time I’ll do the diff service as it’s very easy to access on this car.
