Our 2008 Toyota Highlander Hybrid has a leak that the local Toyota dealer (in Spokane) says is at the silicone transmission seal. The shop manager indicated that they have never seen this before and don't get many Hybrids in. The car is about 10 years old. Some part of me says, I should probably call the Toyota dealer in Seattle because they probably see tons of Hybrids. Is it rare for a transmission leak to show up in a Hybrid? It seems like it should be just as common as a regular car. Any recommendations on where to take the car to be looked at?
