The 2016 Toyota Prius belongs to the 4th generation XW50 (2016-2022), built with 1.8L 2ZR-FXE with an improved hybrid transaxle, plus an available all-wheel-drive variant. It takes 0W-20 full synthetic. Oil changes run 10,000 miles. This is the first model year of that generation, so it is the build most likely to carry early-production quirks and the most likely to have accumulated technical service bulletins.
A 2016 Toyota Prius is 10 years old in 2026, which at an average 12,000 miles a year puts it around 120,000 miles - high mileage. Near 120,000 miles you are past spark plugs, likely on a second set of brakes, and into suspension bushings, hoses and the water pump. Repairs start to outnumber scheduled services, and a written history is what tells you whether an item is due or already done. On that mileage estimate it should already have had spark plugs on most long-life applications at 120,000 miles, and the next milestone is 150,000 miles - transmission fluid again, plus hoses, mounts and suspension bushings - roughly 2.5 years away at average use.
The fault most worth knowing about on this generation is Hybrid battery cooling fan blockage remains the most preventable fault. Owners also report Brake actuator faults on some builds prompting recall attention; and Friction brake components can seize from underuse, since regeneration does most of the work. None of these are certainties on any individual vehicle - they are the patterns worth checking for when you buy or when a symptom appears.

The table above is indexed by service interval. This is the same schedule indexed by odometer reading, for when you know your mileage and want the list. If your odometer sits between these figures, work back to the last one you passed and catch up anything skipped.

Maintenance keeps these away, but when the dash does light up these are the codes this vehicle throws most often - each with what it means and what the repair actually costs.
