I don't trust those numbers for the hybrids. I have a hybrid and replaced the hybrid battery pack. It was expensive. I'd expect a dealer quote for a replacement would run several thousand dollars. I'd also expect the average battery to be replaced at least once in those ten years. That cost would be most of the average upkeep cost You have options for non-oem battery packs that are less expensive, but you are going to have problems finding an independent shop who will work on it. Dealers won't work with non-oem parts, and most shops won't want to work on the HV electrical system in your hybrid. I haven't found a local independent shop who will work on the hybrid systems. You can do some work yourself, the companies that sell non-oem battery packs will tell you that you can. But you should definitely be comfortable working with HV electrical systems if you want to do it yourself. Some independent shops will work on hybrid systems, I found a mechanic with a great reputation that I'm really happy with. He was literally half the price of some of the dealer quotes. But he's in an entirely different state. Independent shops that specialize in hybrids are hard to find. Plus there are other systems involved with the hybrid, like the transmission, that I would assume would usually be a dealer repair. So I'm assuming this list isn't including the costs to repair the hybrid systems. I think those will usually be dealer repairs.
