Because , because , because, that's my job......
Car comes in for an oil change, my job is to do a 26 point inspection, in addition to the oil change.......I write up anything I find wrong....what is wrong with that?
Of course the shop is trying to up sell.....as am I......if we get a repair out of what I find, I get a %......that is the incentive for me to look for problems.....
No shop makes money on an oil change......they make money by up selling......if I see/hear a brake wear sensor touching a rotor, I shouldn't report it? When I see this, I take the time to pop the wheel off, and mic the rotor(during the oil change), so that there are no surprises later......so I take exception with what you said JCat.....Part of an oil change is checking the air filter.......I shouldn't report a fluid leak? Exhaust leak? Rusting fuel/brake lines? Looseness in the front end? Badly worn tire? A light in the dash? A front or rear light out?
Why do we do this? Competition, mainly.......if a car needs work, why let the car leave and go elsewhere for the work? We are in the business of repairing cars....if there is something wrong, we report it......We get way more praises from customers, for reporting this, then the negative attitude of the poster.....If you don't want to fix what we find, don't do it, but at least you are made aware of a problem.....I take pride in my work and the work my shop did.......
