we don't have the free oil change plan in Canada unless individual dealerships do it and I don't miss the extra paying gimmicks like the charge to add windshield fluid and it's time for new air and passenger air filters and we notice you should get new brakes at the next oil change etc and tire rotation which most garages use the dreaded air gun set at who knows what lbs.
I know we can say no thanks but I'm sure it's routine at dealerships...I've done almost all work on my vehicles like brakes and exhausts and air filters and wiper blades, tire rotations and used torque wrenches on most of the things I've done, and other things like anti-freeze and plugs just to name a few, and as an example on my 99 Camaro SS I've done exhaust modes, replaced a bad steering pump which is no easy job and time consuming, added strut tower brace and added sub-frame connectors and many other things during warranty and out of warranty, and other time consuming jobs like spark plugs, which on some vehicles have at least one plug that's hard to get out and install a new one, which I know there's been mechanics that never changed that one and just left it...the last time I had my SS taken to a garage was to replace a hydraulic clutch cylinder which I couldn't do myself because you need a lift because when the external hydraulic cylinder is replaced, they also do the one at the clutch area and it requires pulling the transmission out to get at that clutch cylinder.
I know my Venue isn't like a Camaro SS, and it's my daily driver and it's still under warranty, and I may have warranty issues by doing my own oil changes, but it's hard to teach an old dog new tricks...I always had a very good relationship with the dealerships where I've bought my vehicles, and I live in a small area where we almost know everyone, and because of this, I think the relationship with customers are closer here then large cities...and so far, the only time I needed recent warranty work, was only minor, like my radio/cd player needed to be replaced and a clocking spring in a steering wheel was broke...and because I buy the service manuals for my vehicles which are the type the mechanics will use, I'm able to diagnose and sometimes able to prevent problems...this is why I do many things myself and I don't tell people to do what I do...as well the way our vehicles are getting it gets harder for us backyard mechanics to do things, other then things like oil changes.
