I've had my S90D for 10 months and have 24k miles . I had been planning on taking it in at 1 year anniversary for the first service, but it seems like it might be a waste of money. Here's my thoughts: The brakes are great when I rarely use them. The tires still have good tread. The wipers work like new (ok). The hvac is doing well. I guess I could replace the cabin air filter myself for almost nothing. The battery coolant doesn't get changed for another 25k miles . I live near Cincinnati - not much snow /salt thus far. The steering tracks fine and tread wear is even. Not sure rotation is really needed. Do they automatically replace the 12v battery? I might just wait another year or so - when I'll need new tires and battery coolant change - or do it if an issue occurs. Am I being irresponsible? In previous cars, I kept up with oil and transmission maintenance, but this seems less important.
