Outback battery basics
Subaru's handbook warrants the 12-volt battery for 2 years, well short of the car's 5 years, so a battery that tires at three or four years isn't unusual. Ask for a test of the battery and the charging system first, then a battery to the manual's spec.
Outbacks that tow, run a fridge or sit for weeks wear batteries harder. Tell the mechanic how yours is used, because that changes what they'd fit.

Reading the schedule
Those are Subaru's figures for normal driving, taken from the Warranty and Service Handbooks. The non-XT schedule runs eight services and then repeats. Subaru counts towing, dusty or rough roads and frequent short trips as reasons to service more often, which takes in plenty of Outbacks.
The CVT (a gearbox that uses a belt and pulleys in place of fixed gears) has no scheduled fluid change in the newer schedule unless the car works in extreme conditions. It's still inspected at every service.
Common Outback problems by era
CVT, 2010 to 2015 builds: CarsGuide says Subaru's CVT problems appear to mainly affect cars from those years. Owners reported slow selection of gears and lumpy low-speed driving, and Subaru's fixes were a fluid change and a software reflash.
2.5-litre petrol, 2014 build: CarsGuide's used review says to avoid one with a 2014 build plate because of oil use, with the fix not in place until 2015. Small oilways in these engines don't tolerate dirty oil.
Diesel: without regular highway running the particulate filter can clog. If a DPF warning light comes on, read that page before you book anything.
Timing: CarsGuide says the 2014 to 2025 engines all use chains. Older 2.5-litre four-cylinder Outbacks have a belt, while the six-cylinder uses a chain.
Warranty and who services it
Subaru's handbook excludes failures caused by work from someone other than an authorised Subaru Retailer, or by servicing that isn't to its specifications. That's about faults the work causes. A qualified independent mechanic servicing your Outback to Subaru's schedule and specifications doesn't by itself void the new car warranty. The regulators' guide adds that a defect an independent repairer causes is a matter for that repairer, so pick one who'll follow the handbook item by item.

Our take on an Outback
Go by the handbook column that matches your car, and ask for the estimate to name each item due at that service. If you tow or drive dirt roads, ask the mechanic whether the severe schedule fits. On a 2010 to 2015 CVT car, mention any hesitation now, while a fluid change and an update might still be the answer.
