I purchased a brand-new prius in 2011 had all my services done there. about 4 yrs later I started having an oil leak with no explanation why, so I ended up adding oil more often, that wasn't cheep. needless to say after my warranty was up I YouTube how to change my own oil so I can save money because before it had to be done by a certified mechanic so I watched how easy and much cheaper it was. so I slide under my car for the first time in 6 yrs to find out the door cover for my oil filter and drain plug was missing. so I take off the drain plug and there was no gasket on the plug. explanation for the leak....ive also came up with 2 missing hub caps that they said they didn't have in there garage when I asked what happened to them. it's a shame that you cant even trust the dealerships.
