I was speaking with someone at work today about how I am due for a car service appt because my Mantenance Required light is on. He told me that his is always on because he takes his car to a local mechanic for servicing. He told me that it is a scam by the manufacturer and that outside mechanics cannot turn these lights off because the manufacturer does not give out the code to de-activate the light. It can only be turned off if you bring it to the Manufacturer for service. This has never been an issue for me since I get free oil service from my dealership, so I found this practice interesting. But I do wonder how the Manufacturers can do this. It seems to me like you buy a car from them but they use this maintenance light to hold you hostage for their servicing, at inflated prices, of course. If this is true, I have some resentment toward that practice. I know a light on the dashboard is not the end of the world, but it can be irritating to have that light on all the time unless take the car to your manufacturer for service.
