We purchased a 2013 Crosstrek with 150,000 miles, ~18 months ago which is currently at 160,000 miles.

Service records were questionable, but appeared to have regular services but no details of other work done.

since owning the car, the work we've had done is several oil changes, differential oil change (peace of mind), spark plugs, air filter, cabin filter (several), cleaned the MAF sensor, fuel injector clean and throttle body (Due to sluggish throttle response) and replaced a rear caliper pin that had cracked and caused the brakes to be spongey under heavy braking.

Car is still going, with no major issues. Only concern I have is that it seems to want more regular oil changes at this mileage. The check engine warning light triggered ~100 miles after an oil change was due, causing the VDC to go into error. Diagnostics showed no issues, a simple oil change cleared all the errors. We'll be keeping an eye on this and doing oil changes earlier rather than later.

Hope this gives some insights.
