Have you taken a look at what's under the hood of your car lately? I can tell you one thing's for sure; they don't make them like they used to. With the way hybrid technology is taking off, it's only a matter of time before the gas engine is completely gone from under the hood.
For now, though, gas engines are here to stay. The gas-electric hybrid technology is complicated enough that you need a certified dealer to perform maintenance or repairs. But this story just goes to show, the guys at the dealership might not always know what they're doing.
One man took his car in for repair, but the dealership wanted $4,400 to fix it. He did some tinkering and repaired it himself for less than $10!
