I'm with you on that. I had my tire shop look carefully at my owners manual before I let them do the work on my volt because I saw the thread on crushed pipes (I think they were transmission fluid cooler pipes?) underneath.In 2 years I've had the tires rotated (2x) and the oil changed once. Done at a dealership and covered under the 24 month free maintenance from when I purchased the Volt.
I'm a little hesitant about letting anyone other than a dealer touch the Volt. In MA the yearly inspection includes frame and steering components. To check these, the mechanic uses a floor jack to lift the car. I go to the dealer because I'm afraid that in their haste, they'll miss the reinforced jack points and damage something. I think the Volt is just too new with too many quirks to leave to someone not versed in its Idiosyncrasies.
I don't worry about that myself with oil changes but you do have a valid point.Although I'm perfectly capable of changing the oil and rotating the tires, I have the dealership change the oil only because if they screw it up it's on them to honor the powertrain warranty.
Tire wear and rotating is a funny thing. On my Jeep the passengers side rear tire is the "driver" and that single tire is the one that wears faster than anything else. So a regular schedule of rotation shares that wear between all the tires giving me a nice long life for all four thus rotations make sense...for that vehicle.I used to rotate my tires, but I've even stopped doing that. I now wear down the fronts, then move the rears to the front and buy new rear tires. The first set of replacement fronts lasted 40k miles and are still going, where the rears should get me 70-80k miles after I move them to the front.
